FG-02-FP: 电暖器/取暖器正常使用

有人在房间且温度上升后趋于稳定（不是持续飙升），无烟雾报警触发

No safety anomaly detected; the evening routine including cooking and locking is consistent with normal household activity.

Explanation: The kitchen temperature rise (23.4°C to ~27.1°C) correlates directly with the activation of the cook surface at 18:49 and its deactivation at 19:34, indicating a standard cooking event rather than a malfunction or fire hazard.

Explanation: The 'unattended cooking' hypothesis from the investigator is refuted by the context: the user was continuously present in the adjacent living room (Occupancy=1), making it highly probable they were supervising the cooking process despite the lack of explicit kitchen occupancy logs.

Explanation: The transient `None` value for the kitchen temperature sensor at 18:50 recovered immediately and did not persist, which is insufficient evidence for a device fault or sensor malfunction according to Matter protocol standards.

Explanation: The front door lock sequence in C19 shows a successful auto-lock operation after the contact sensor confirmed closure, establishing a secure state for the night without any signs of intrusion or lock failure.

Explanation: Overall, the sequence of events (entry, cooking, cleanup, locking) forms a coherent and safe daily routine.

C15/C16: Cook surface turned on at 18:49 and off at 19:34, with temperature spike confirming usage.

C15-C19: Continuous Living Room occupancy indicates presence during cooking and evening activities.

C19: Successful auto-lock event at 22:13 confirms security system functionality.

Monitor future cooking events to see if automated alerts are desired for unattended stove duration.

Kitchen temperature anomaly indicating active cooking or appliance usage

Evening entry/lock sequence at front door

Occupancy patterns correlating with activity zones

These two chunks provide the necessary context for both environmental hazards (cooking heat) and physical security (locking up), covering the primary safety dimensions requested.

Normal evening routine with active cooking and subsequent cleanup. The kitchen temperature rise was caused by the cook surface being turned on, and the risk was mitigated when the user manually turned it off after ~45 minutes of use.

C15 shows kitchen_temp_sensor rising from 25.75°C to a peak of 27.14°C between 18:15 and 18:35, correlating with the activation of kitchen_cook_surface at 18:49:30 (Note: Timestamps in C15 show temp rise *before* explicit 'on' log for cook surface, but temp rise is consistent with appliance usage).

C16 explicitly logs `kitchen_cook_surface | OnOff.OnOff = off` at 19:34:00, confirming the hazard source was deactivated.

Post-19:34, kitchen temperatures drop rapidly from ~22.8°C to baseline (~22.5°C) by 19:40, indicating no sustained heat generation.

Front door lock sequence in C19 (22:13) shows a successful auto-lock event (`LockOperationType=0`) with contact sensor confirming closure, establishing a secure state for the night.

Occupancy patterns show continuous presence in living_room/entrance during the evening, suggesting supervision.

The specific moment the cook surface was turned 'on' is not explicitly logged as an 'OnOff' transition in the provided chunks (only 'off' is seen in C16), relying on inference from temperature rise.

There is a brief telemetry gap (`None`) for the kitchen temp sensor at 18:50:00, which coincides with the start of cooking activity, though it recovers immediately.

Unattended Cooking Risk / Potential Fire Hazard. The cook surface was activated around 18:49 (inferred from context/temp) and remained on until 19:34. During this ~45 minute window, there is no evidence of direct supervision in the kitchen (occupancy sensors only track Living Room/Entrance/Bathroom/Bedrooms), and the kitchen temperature spiked significantly before dropping. While the stove was eventually turned off, the lack of explicit 'supervision' logs or immediate mitigation raises a safety concern regarding unattended heating.

C15: Kitchen temperature rises steadily from 25.75°C (18:15) to 27.14°C (18:35) and stays elevated through 18:45.

C15: `kitchen_cook_surface | OnOff.OnOff = on` occurs at 18:49:30.

C16: `kitchen_cook_surface | OnOff.OnOff = off` does not occur until 19:34:00, a duration of ~45 minutes.

During the 18:49-19:34 window, `kitchen_occupancy` is not reported (only bathroom/living_room/entrance are tracked), meaning we cannot confirm a person was physically present in the kitchen.

No smoke_co_alarm or water_leak_detector events were triggered, implying the situation did not escalate to an emergency, but also that no automated safety check-back occurred.

The user was likely in the house (Living Room occupancy was high), so 'unattended' might refer to leaving the room briefly rather than leaving the house entirely.

The stove was successfully turned off, preventing actual fire damage.

Temperature readings recovered quickly after shutdown, showing no thermal runaway.

Sensor Telemetry Glitch. The kitchen temperature sensor reported `None` at 18:50:00, exactly one minute after the cook surface was turned on. This suggests a potential transient communication fault or sensor overload due to heat proximity, although it recovered instantly.

C15: `kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None` at 18:50:00.

C15: Immediately following, at 18:50:00 (same timestamp block), a valid value `26.24 C` is recorded, indicating recovery.

Similar `None` reading appears again at 19:35:00 in C16, shortly after the stove was turned off, suggesting intermittent connectivity issues rather than a permanent failure.

The glitch was isolated and self-correcting within seconds.

It did not prevent the eventual detection of the 'off' state or the temperature drop.

C16: `kitchen_cook_surface | OnOff.OnOff = off` at 19:34:00 confirms the end of the heating event.

C15-C16: The ~45 minute duration of the cook surface being 'on' without explicit kitchen occupancy confirmation creates the unattended cooking risk profile.

C19: Successful auto-lock at 22:13:47 confirms the security system functioned correctly for the night cycle.

C15/C16: Transient `None` values for kitchen_temp_sensor at 18:50 and 19:35 indicate minor sensor instability but not total failure.

Direct `kitchen_occupancy` data to confirm if a person was present in the kitchen during the 18:49-19:34 cooking window.

Explicit `OnOff` 'on' event for the cook surface to precisely define the start time (currently inferred from temperature trends and the 'off' log timing relative to activity).

Smoke detector status logs to definitively rule out any hazardous byproducts (smoke/gas) during the cooking period.

The investigator relies on the absence of `kitchen_occupancy` logs to infer 'unattended' status. However, Matter occupancy sensors often report only on state changes or periodic heartbeats; a lack of explicit 'occupied' log does not prove the room was empty, especially given the concurrent activity in adjacent rooms (living_room) and the presence of cooking events.

The 'sensor_malfunction' hypothesis is based on a single transient `None` value that immediately recovered. This is insufficient evidence for a device health fault conclusion without repeated failures or persistent errors.

The investigation fails to explicitly check the `smoke_co_alarm` status during the cooking window to rule out hazardous byproducts, relying instead on the absence of an alarm trigger as proof of safety (which is weak evidence for 'no risk', though strong for 'no emergency').

The query asks for a comprehensive safety assessment, but the analysis focuses heavily on interpreting telemetry gaps rather than synthesizing the full sequence of events (entry, cooking, locking) into a coherent safety narrative.

Protocol Misunderstanding: The investigator treats missing occupancy logs as definitive proof of an unoccupied room ('unattended cooking'). In Matter/Smart Home contexts, occupancy sensors may have debounce times, reporting intervals, or may simply not log if the state hasn't changed since the last heartbeat. The presence of the user in the Living Room (adjacent to Kitchen) makes 'unattended' less likely than 'cooking while nearby'.

False Alarm Risk: High. The 'unattended cooking' risk is speculative because it depends entirely on the assumption that no one was in the kitchen, which is not supported by direct evidence (only absence of specific logs). The 'sensor malfunction' is also low-confidence due to immediate recovery.

Evidence Gap: While C15-C16 cover the cooking event, the analysis should verify if any other devices (e.g., range hood, dishwasher) provide context for the kitchen activity. More importantly, the conclusion about 'safety' needs to weigh the successful lock-down (C19) against the cooking event. The current output is too focused on potential faults rather than the overall safety posture.

Action: Refine the investigation to clarify the definition of 'unattended' in this context. If the system lacks kitchen occupancy sensors, the risk assessment must account for that limitation explicitly rather than inferring absence from silence. Do not conclude 'device fault' from a single transient glitch.

Normal evening routine with active cooking and subsequent secure locking.

C15 shows kitchen temperature rising from 25.75°C to a peak of 27.14°C between 18:15 and 18:35, consistent with cooking activity.

Kitchen cook surface turned ON at 18:49:30, correlating with the elevated temperatures.

Kitchen temperature began decreasing after 18:45 (26.71°C -> 25.82°C -> ... -> 24.52°C), suggesting the heat source was removed or turned off before the end of the chunk.

C19 shows the front door lock engaging automatically at 22:13:47 with LockState=locked, indicating successful security protocol execution.

Occupancy sensors show people present in Living Room and Entrance during these times, supporting normal household presence.

Does not fully explain the brief `None` reading for the kitchen temp sensor at 18:50:00, though this is minor.

Assumes the temperature drop implies the stove was turned off, but doesn't explicitly confirm the `OnOff` state change for the cook surface in C15 (only the 'on' event is logged).

Potential unattended cooking risk due to lack of explicit 'off' confirmation and temporary sensor dropout during active heating.

Kitchen cook surface turned ON at 18:49:30.

Kitchen temperature peaked at 27.14°C at 18:35 and remained high (26.71°C) at 18:45, just before the stove was turned on.

At 18:50:00, exactly one minute after the stove was turned on, the kitchen_temp_sensor reported `MeasuredValue = None`, creating a blind spot in monitoring the immediate post-ignition phase.

While temperatures later decreased, there is no explicit log entry in C15 showing the cook surface turning OFF, leaving a gap in verifying that the hazard was actively mitigated by the user.

The combination of an active heat source, a momentary loss of environmental telemetry, and no explicit 'off' command creates a window where unattended cooking could have occurred without detection.

The temperature did decrease significantly after 18:50, which strongly suggests the stove was eventually turned off or the cooking finished, making a catastrophic fire unlikely.

The `None` reading might be a transient network glitch rather than a failure caused by heat, as other sensors continued reporting.

No smoke alarm or CO alarm events were triggered, reducing the likelihood of a severe fire event.

Sensor malfunction or communication error indicated by intermittent data loss.

At 18:50:00, `kitchen_temp_sensor` returned `MeasuredValue = None` while all other room sensors (living_room, master_bedroom, second_bedroom) returned valid values simultaneously.

This isolated dropout suggests a specific issue with the kitchen sensor or its local connection, rather than a system-wide outage.

It was a single, isolated event (`None`) followed immediately by a valid reading (26.24°C) at the same timestamp (likely a retry or next cycle).

Matter notes specify that scaled temperature values alone are not enough for fault conclusions, and a single transient dropout is insufficient to claim permanent malfunction without repetition.

The sequence in C15: Kitchen Temp rises -> Cook Surface ON -> Temp Sensor None -> Temp drops. The 'None' value coincides with the start of active cooking.

The absence of an explicit 'Cook Surface OFF' event in the logs, despite the temperature dropping.

The successful automatic lock event in C19 confirms the lock mechanism is functional, ruling out lock_malfunction.

Explicit 'Off' state change for the kitchen_cook_surface after 18:49:30.

Status of the smoke_co_alarm device mentioned in the query anchor (no logs provided for it in the chunks).

Confirmation of whether the kitchen occupancy sensor detected anyone remaining in the kitchen after the cooking activity ceased.

C16 explicitly logs `kitchen_cook_surface | OnOff.OnOff = off` at 19:34:00, confirming the hazard source was deactivated.

Occupancy patterns show continuous presence in living_room/entrance during the evening, suggesting supervision.

C15: Kitchen temperature rises steadily from 25.75°C (18:15) to 27.14°C (18:35) and stays elevated through 18:45.

C15: `kitchen_cook_surface | OnOff.OnOff = on` occurs at 18:49:30.

C16: `kitchen_cook_surface | OnOff.OnOff = off` does not occur until 19:34:00, a duration of ~45 minutes.

C15: `kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None` at 18:50:00.

C15: Immediately following, at 18:50:00 (same timestamp block), a valid value `26.24 C` is recorded, indicating recovery.

Verify if kitchen_cook_surface turned OFF in chunks C16-C18 to confirm mitigation of fire risk.

Check for smoke_co_alarm or water_leak_detector events in the full report as requested by query anchor.

Confirm if the 'None' reading was a transient glitch or persistent fault by checking adjacent timestamps.

The investigator correctly identified the cooking event and the subsequent temperature drop, but failed to verify the critical 'OFF' state of the cook surface within the provided chunks (C15 ends before the stove is confirmed off).

The 'unattended_cooking' hypothesis relies heavily on the absence of an 'OFF' log and a single 'None' telemetry gap. Without confirming the stove was turned off in the immediate following minutes (likely in C16-C18), the safety conclusion is speculative.

The query explicitly asks about 'smoke_co_alarm' and 'water_leak_detector', which are completely ignored in the current analysis despite being listed in the target devices.

Marking false-alarm risk as high because the primary safety concern (fire) is inferred from missing logs rather than positive evidence of hazard escalation or explicit alarm triggers.

Requesting adjacent chunks to close the loop on the cooking activity and to check the status of other targeted safety devices.

FG-03-FP: 烟雾报警器自检触发CO检测

Cooking activity lasted approximately 43 minutes with a significant temperature spike in the kitchen, followed by immediate window opening and stove shutdown, suggesting potential unattended cooking or reaction to heat/smoke despite no alarm triggering.

Explanation: The investigator identified a security risk (unlocked door) which was resolved by auto-lock at 21:58. However, the supervisor noted that C19 is needed to confirm the final state, but the cooking event occurred earlier and presents a distinct safety concern.

Explanation: Evidence from C15-C16 shows the kitchen cook surface turned on at 19:02 and remained on until 19:45 (43 minutes). During this time, kitchen temperature rose from ~23°C to a peak of 26.86°C.

Explanation: At 19:45, immediately after the stove was turned off, the kitchen window contact sensor changed to 'false' (open). This correlation suggests the window was opened to vent heat or smoke, or as part of a hasty shutdown sequence.

Explanation: While no smoke/CO alarms triggered, the duration of cooking combined with the environmental response (window opening) and lack of explicit kitchen occupancy logs creates a plausible scenario for unattended cooking or near-miss fire risk.

Explanation: The supervisor's request for C19 pertains to the *current* security status post-21:58. Since the door locked successfully at 21:58 and no further breaches are logged in C18 (up to 22:10), the current security state is likely secure. However, the question asks for an analysis of the *comprehensive* report to identify *potential risks*. The cooking event represents a verified past risk that fits the 'unattended_cooking' profile better than 'fire_risk' (no actual fire) or 'intrusion'.

Explanation: We must distinguish between the resolved security lapse (door unlocked) and the cooking anomaly. The door lock issue is a behavioral anomaly/security lapse, but the cooking event involves a hazardous device (stove) and environmental changes. Given the rules for `composite-safety`, we should flag the most significant safety hazard. The cooking event is a strong candidate for `unattended_cooking` due to the duration and subsequent ventilation action.

C15: kitchen_cook_surface OnOff=on at 19:02:30.

C16: kitchen_cook_surface OnOff=off at 19:45:00 (43 min duration).

C16: kitchen_temp_sensor peaked at 26.86 C at 19:35.

C16: kitchen_window_contact BooleanState=false (open) at 19:45:30, immediately following stove shutdown.

Review kitchen occupancy logs if available to confirm supervision during the 19:00-19:45 window.

Check if the window opening was intentional ventilation or accidental.

Verify the front door lock state in C19 to ensure no late-night breaches occurred after the auto-lock.

Unsecured entry point (door unlocked/open) during occupied hours

Potential security risk due to lack of immediate lock engagement after entry

Normal occupancy patterns vs. security state mismatch

The home is currently secure. The front door was left unlocked for an extended period (approx. 3 hours) after entry, likely due to occupant activity or forgetfulness, but the auto-lock mechanism engaged successfully at 21:58, securing the perimeter.

C17 shows continuous occupancy in the living room and entrance from 20:12 to 21:58, indicating the house was occupied during the unlocked period.

C18 records `front_door_lock` Event: LockOperation with `OperationSource=Auto` and `LockState=locked` at 21:58:37.

No smoke/CO alarms were triggered during the cooking event (C15-C16), suggesting no fire occurred.

Kitchen temperature returned to baseline (~22.5 C) by 21:15 (C17), indicating the heat source was removed and ventilation/cooling normalized the environment.

The long duration of the unlocked state (18:21-21:58) represents a significant security lapse if not intentional (e.g., waiting for someone).

Relies on the assumption that 'Auto' lock implies a successful mechanical operation without fault, though the state change confirms it.

Cooking activity was supervised and safe. The cook surface was turned off promptly, and the kitchen temperature spike was consistent with normal cooking, dissipating quickly.

C15 shows `kitchen_cook_surface` turned on at 19:02:30.

C16 shows `kitchen_cook_surface` turned off at 19:45:00, approximately 43 minutes later.

Kitchen temperature rose from ~23 C to ~26.8 C (C16) then dropped back to ~22.5 C (C17), showing a clear peak and recovery curve typical of cooking.

Occupancy sensors in the living room remained active throughout the cooking period, suggesting occupants were nearby.

Does not account for whether the person cooking was actually present in the kitchen or just left the appliance on while moving to the living room.

Does not explain the window contact state change at 19:45.

Security Risk: Unsecured Entry Point. The front door remained unlocked for over 3 hours (18:21-21:58) despite being occupied. While it eventually locked automatically, this represents a prolonged vulnerability window where unauthorized entry could have occurred.

C15: `front_door_lock` set to `unlocked` at 18:21:00 via Manual operation.

C15-C17: No lock engagement events recorded between 18:21 and 21:58.

C15-C17: `entrance_occupancy` and `living_room_occupancy` consistently report `occupied` (raw=1) throughout this entire period, confirming the home was inhabited but the primary entry point was open.

C18: Lock only engages at 21:58:37 via Auto-lock, ending the insecure state.

The eventual auto-lock resolves the immediate threat, making it a resolved anomaly rather than an ongoing emergency.

Could be explained by normal behavior (e.g., user forgot to lock, or kept it open for ventilation/pets) rather than malicious intent.

Potential Fire Risk / Unattended Cooking. The cook surface was active for ~43 minutes. Although no alarm fired, the lack of explicit kitchen occupancy logs during the peak heat phase (19:00-19:45) combined with the window opening suggests a potential lapse in supervision or a reaction to heat/smoke.

C16: Kitchen temp peaks at 26.86 C at 19:35, then drops slightly as cook surface turns OFF at 19:45:00.

C16: `kitchen_window_contact` changes to `false` (open) at 19:45:30, immediately after the stove is turned off. This correlation suggests the window was opened possibly to vent heat/smoke or as part of the shutdown process.

C15-C16: No explicit `kitchen_occupancy` sensor data is provided in the focused chunks (only living_room/entrance are detailed), creating a blind spot on direct supervision of the hazard zone.

No smoke/CO alarms triggered, which strongly argues against a dangerous fire condition.

Temperature rise was moderate and recovered quickly, inconsistent with uncontrolled fire.

Living room occupancy was constant, implying someone was in the adjacent space.

Sensor Telemetry Gap / Blind Spot. The kitchen temperature sensor reported `None` at 19:03:00 and 19:46:00, coinciding with high-activity periods (cooking start/end). This may indicate sensor malfunction or temporary disconnection during critical safety monitoring windows.

C15: `kitchen_temp_sensor` | TemperatureMeasurement.MeasuredValue = None at 19:03:00 (1 minute after stove on).

C16: `kitchen_temp_sensor` | TemperatureMeasurement.MeasuredValue = None at 19:46:00 (1 minute after stove off and window opened).

Values return to normal immediately before and after these gaps.

Isolated incidents of `None` values are common in IoT devices (network dropouts, sleep cycles) and do not necessarily indicate permanent failure.

Other sensors (living room, etc.) continued reporting normally, suggesting the issue is local to the kitchen device or network segment, not a system-wide outage.

C18: `front_door_lock` Event: LockOperation(LockOperationType=0, OperationSource=Auto) at 21:58:37 resolving the 3-hour unlocked state.

C15-C16: Timeline of cook surface ON (19:02) -> Temp Peak (19:35) -> Cook Surface OFF (19:45) -> Window Open (19:45).

C15: `front_door_lock` DoorLock.LockState = unlocked (raw=2) at 18:21:00 with no subsequent lock event until C18.

Direct `kitchen_occupancy` logs to confirm if anyone was physically present in the kitchen during the cooking event.

Confirmation of why the window was opened at 19:45 (ventilation vs. security breach attempt).

Logs for any other entry points (back door, garage) to rule out simultaneous intrusion attempts during the unlocked front door period.

C18 records `front_door_lock` Event: LockOperation with `OperationSource=Auto` and `LockState=locked` at 21:58:37.

No smoke/CO alarms were triggered during the cooking event (C15-C16), suggesting no fire occurred.

C15 shows `kitchen_cook_surface` turned on at 19:02:30.

C16 shows `kitchen_cook_surface` turned off at 19:45:00, approximately 43 minutes later.

Occupancy sensors in the living room remained active throughout the cooking period, suggesting occupants were nearby.

C15: `front_door_lock` set to `unlocked` at 18:21:00 via Manual operation.

C15-C17: No lock engagement events recorded between 18:21 and 21:58.

C18: Lock only engages at 21:58:37 via Auto-lock, ending the insecure state.

C16: Kitchen temp peaks at 26.86 C at 19:35, then drops slightly as cook surface turns OFF at 19:45:00.

C15: `kitchen_temp_sensor` | TemperatureMeasurement.MeasuredValue = None at 19:03:00 (1 minute after stove on).

C16: `kitchen_temp_sensor` | TemperatureMeasurement.MeasuredValue = None at 19:46:00 (1 minute after stove off and window opened).

Values return to normal immediately before and after these gaps.

Verify the final state of the front door lock in the post-21:58 period (Chunk C19) to confirm it remained locked and did not reopen.

Check for any smoke/CO alarm events in the full log set, as they are critical for ruling out fire risk definitively.

Confirm if 'kitchen_window_contact' state change at 19:45 was a transient event or persisted, to assess ventilation vs. security breach intent.

The investigator correctly identified the primary security anomaly (unlocked door during occupancy) and the cooking timeline.

However, the investigation is incomplete because it stops at Chunk C18 (ending ~22:10). The query asks for the 'current safety condition'. We need to see if the auto-lock held or if there were subsequent breaches in the evening (C19+).

The 'sensor malfunction' hypothesis (A3) regarding temperature `None` values is flagged as medium risk. While isolated `None` values are common, the investigator should explicitly state that this does not constitute a device fault without further evidence (repeated failures, alarms), which is currently absent. This prevents over-diagnosing hardware issues.

The fire risk assessment relies heavily on the absence of alarms and normal temp recovery, which is good, but the missing kitchen occupancy data remains a blind spot. However, given the lack of alarm triggers, the risk is likely low, but the 'current status' cannot be fully certified until the end-of-day logs are reviewed.

Requesting C19 to close the loop on the night's security status.

Normal evening routine with temporary security lapse: The resident entered the home, left the front door unlocked (possibly for convenience or due to a delayed auto-lock), and proceeded to cook dinner. The kitchen temperature rise is consistent with cooking activity, and the eventual shutdown of the cooktop indicates normal completion of the meal.

C15 shows entrance_occupancy = occupied starting at 18:21, coinciding with lights turning on in the entrance and living room.

C15 shows front_door_lock = unlocked (raw=2) and front_door_contact = false (open) at 18:21.

C15 shows kitchen_cook_surface turned on at 19:02.

C16 shows kitchen_cook_surface turned off at 19:45.

Kitchen temperature rises from ~23°C to ~26-27°C during cooking (C15/C16), which is expected behavior for a heated appliance in a small space.

Living room and entrance occupancy remain high throughout the evening, suggesting someone is present in the house.

The front door remained unlocked for over an hour (18:21 to end of logs) while the house was occupied, which is a security risk even if intentional.

No explicit 'lock engaged' event is recorded after entry, leaving the state ambiguous regarding whether it was forgotten or malfunctioning.

Security Risk: Unsecured Entry Point During Occupancy. The front door was left open/unlocked for an extended period (>50 minutes) immediately after entry, creating a potential vulnerability for intrusion or unauthorized access, despite occupants being present.

C15: At 18:21:00, front_door_lock is 'unlocked' and front_door_contact is 'false' (open).

C15: Entrance occupancy is 'occupied' continuously from 18:21 through 19:15.

C16: No lock engagement events are recorded between 18:21 and 20:11.

C15: Living room and entrance lights/AC activated, indicating active habitation, yet the primary entry point remains unsecured.

Occupancy sensors confirm people are inside, reducing the immediate likelihood of successful intrusion compared to an empty home.

It is possible the user manually locked the door via a physical key or app not captured in these specific Matter logs, though no log evidence supports this.

Potential Fire Risk / Unattended Cooking Hazard. Cooking activity occurred in the kitchen while the primary occupant presence was logged in the living room/entrance, and the kitchen temperature spiked significantly. While the cooktop was eventually turned off, the lack of direct kitchen occupancy confirmation during the heating phase presents a mild safety concern.

C15: Kitchen cook surface turned ON at 19:02.

C15: Kitchen temperature sensor reads None at 19:03, then jumps to 24.26°C at 19:05, rising to 26.86°C by 19:30.

C15/C16: Kitchen occupancy is not explicitly logged as 'occupied' in the same frequent manner as entrance/living room; only entrance and living room have dense occupancy pings.

C16: Cook surface turned OFF at 19:45, ending the heating event.

The cooktop was turned off within ~43 minutes, which is a reasonable duration for cooking, not necessarily 'unattended'.

Temperature rise, while notable, is consistent with normal cooking heat output and did not reach critical levels.

C15: front_door_lock | DoorLock.LockState = unlocked (raw=2) at 18:21:00 with no subsequent lock event.

C15: front_door_contact | BooleanState.StateValue = false (raw=False) at 18:21:02, confirming the door was physically open.

C15: entrance_occupancy | OccupancySensing.Occupancy = occupied (raw=1) continuously from 18:21 onwards, proving the house was inhabited during the insecure state.

Logs for any manual lock engagement commands or physical key usage that might explain why the door was left unlocked.

Direct occupancy data for the kitchen itself to confirm if someone was actually present near the stove during the heating phase.

Status of the front door contact sensor after 18:21 to see if it changed state (implying the door was closed but not locked, or opened/closed multiple times).

C18 records `front_door_lock` Event: LockOperation with `OperationSource=Auto` and `LockState=locked` at 21:58:37.

No smoke/CO alarms were triggered during the cooking event (C15-C16), suggesting no fire occurred.

The long duration of the unlocked state (18:21-21:58) represents a significant security lapse if not intentional (e.g., waiting for someone).

Relies on the assumption that 'Auto' lock implies a successful mechanical operation without fault, though the state change confirms it.

C15 shows `kitchen_cook_surface` turned on at 19:02:30.

C16 shows `kitchen_cook_surface` turned off at 19:45:00, approximately 43 minutes later.

Occupancy sensors in the living room remained active throughout the cooking period, suggesting occupants were nearby.

Does not explain the window contact state change at 19:45.

C15: `front_door_lock` set to `unlocked` at 18:21:00 via Manual operation.

C15-C17: No lock engagement events recorded between 18:21 and 21:58.

C18: Lock only engages at 21:58:37 via Auto-lock, ending the insecure state.

The eventual auto-lock resolves the immediate threat, making it a resolved anomaly rather than an ongoing emergency.

Could be explained by normal behavior (e.g., user forgot to lock, or kept it open for ventilation/pets) rather than malicious intent.

C16: Kitchen temp peaks at 26.86 C at 19:35, then drops slightly as cook surface turns OFF at 19:45:00.

No smoke/CO alarms triggered, which strongly argues against a dangerous fire condition.

Temperature rise was moderate and recovered quickly, inconsistent with uncontrolled fire.

Living room occupancy was constant, implying someone was in the adjacent space.

C15: `kitchen_temp_sensor` | TemperatureMeasurement.MeasuredValue = None at 19:03:00 (1 minute after stove on).

C16: `kitchen_temp_sensor` | TemperatureMeasurement.MeasuredValue = None at 19:46:00 (1 minute after stove off and window opened).

Values return to normal immediately before and after these gaps.

C18 records `front_door_lock` Event: LockOperation with `OperationSource=Auto` and `LockState=locked` at 21:58:37.

No smoke/CO alarms were triggered during the cooking event (C15-C16), suggesting no fire occurred.

C15 shows `kitchen_cook_surface` turned on at 19:02:30.

C16 shows `kitchen_cook_surface` turned off at 19:45:00, approximately 43 minutes later.

Occupancy sensors in the living room remained active throughout the cooking period, suggesting occupants were nearby.

C15: `front_door_lock` set to `unlocked` at 18:21:00 via Manual operation.

C15-C17: No lock engagement events recorded between 18:21 and 21:58.

C18: Lock only engages at 21:58:37 via Auto-lock, ending the insecure state.

C16: Kitchen temp peaks at 26.86 C at 19:35, then drops slightly as cook surface turns OFF at 19:45:00.

C15: `kitchen_temp_sensor` | TemperatureMeasurement.MeasuredValue = None at 19:03:00 (1 minute after stove on).

C16: `kitchen_temp_sensor` | TemperatureMeasurement.MeasuredValue = None at 19:46:00 (1 minute after stove off and window opened).

Values return to normal immediately before and after these gaps.

Verify if the front door was locked after the evening logs ended (post-20:11). The current evidence shows the door remained unlocked for over an hour during occupancy, but does not confirm if it was eventually secured or left open overnight.

Check for smoke/CO alarm status in C15/C16 to definitively rule out fire risk associated with the cooking event.

Confirm if 'kitchen_window_contact' state change at 19:45 correlates with any ventilation activity or security breach.

The investigator correctly identified the primary security risk (unsecured door) and the potential fire risk (cooking).

However, the investigation is incomplete because it stops at 20:11. The critical question for 'current safety' is whether the door was ever locked after entry. Without C17 (or later logs), we cannot determine if this was a temporary lapse resolved by the user or a persistent hazard.

The fire risk assessment is reasonable but relies on the absence of alarms rather than positive confirmation of safe conditions; however, the temperature data supports normal cooking behavior.

The main gap is the lack of resolution for the security event. We need to know the final state of the lock.

No protocol format misunderstandings detected (temperatures scaled correctly, booleans interpreted contextually).

BA-04-FP: 传感器触发延迟导致顺序看似跳跃

客厅occupancy在阳台和主卧之间有触发（2秒时），移动路径合理

No confirmed safety anomaly; the home appears unoccupied with stable environmental conditions, though a transient sensor event in C08 remains unverified due to missing log data.

Explanation: The provided evidence (Chunks C09-C15) consistently shows all rooms as 'unoccupied' and temperatures stabilizing within a normal range (approx. 22-25°C), indicating no active fire, leak, or sustained intrusion.

Explanation: The Investigator hypothesized an anomaly based on a 'occupancy spike' in Chunk C08, but the Supervisor correctly identified that C08 is missing from the Focused Chunks, making this hypothesis unverifiable.

Explanation: Without C08 data, we cannot distinguish between a real brief presence (intrusion/pet) and a sensor glitch. However, the subsequent stability in C09-C15 (no lock changes, no alarms, return to baseline occupancy) strongly suggests that if an event occurred, it was either non-threatening or resolved immediately without consequence.

Explanation: Per the rules for composite-safety, we should not conclude an anomaly based mainly on missing supervision assumptions or sparse access logs. The absence of corroborating evidence (lock flips, alarms) in the available chunks makes the intrusion/malfunction hypotheses speculative rather than confirmed.

Explanation: Therefore, the most supported conclusion is that the home is currently safe and unoccupied, but confidence is low because the potential trigger event (C08) was not inspected.

Chunks C09-C15 show consistent OccupancySensing.Occupancy = unoccupied (raw=0) across all monitored rooms.

Temperature readings in C09-C15 are stable and gradual (25°C down to ~22°C), ruling out fire or overheating risks.

No DoorLock state changes or Contact Sensor triggers are recorded in the verified chunks, negating evidence of physical entry/exit during this period.

Chunk C08, which contained the alleged anomaly trigger, is missing from the evidence set, preventing verification of the initial event.

Retrieve and inspect Chunk C08 to verify the nature of the reported occupancy spike.

Check for any pet activity logs or video footage corresponding to the C08 timeframe to rule out animal movement.

Continue monitoring for any recurrence of similar transient occupancy spikes in future logs.

Unoccupied state across all rooms (potential absence)

Stable temperature trends (no fire/overheat risk)

No lock state changes or contact sensor triggers (no intrusion)

No smoke, gas, or water leak alarms triggered

The home is unoccupied and secure. The occupancy spike in C08 was a transient sensor glitch or brief false positive, as all rooms returned to 'unoccupied' status immediately in C09 and remained so for the rest of the day. No security breaches, fires, or leaks occurred.

C09-C17 show consistent 'OccupancySensing.Occupancy = unoccupied (raw=0)' across all monitored rooms (living_room, master_bedroom, second_bedroom, bathroom, entrance).

No DoorLock state changes or contact sensor triggers are recorded in C09-C17, indicating no entry/exit events.

Temperature readings in C09-C17 show stable, gradual cooling trends (approx 25°C down to 22°C) consistent with an empty house losing heat or HVAC adjusting, with no sudden spikes indicative of fire or cooking.

No smoke, gas, or water leak alarms were triggered.

Relies on the assumption that the C08 spike was purely noise without seeing the exact transition back to zero, though C09 confirms the return to baseline.

Transient Security Event / Intrusion Attempt: An unauthorized person briefly entered the home during the C08 window (midday), triggering occupancy sensors, but left before being detected by locks or causing further damage. The lack of lock activity suggests they may have had access (open door/window) or bypassed the lock, or the intrusion was limited to interior rooms not protected by the main door lock.

C08 showed a significant occupancy spike (337 counts) in living_room, master_bedroom, and second_bedroom, contrasting sharply with the baseline of ~48-336 in other chunks and the balcony's 1 count.

C09 shows an immediate reset to 'unoccupied' (raw=0) for all these rooms, suggesting the presence was short-lived or the sensors cleared quickly after departure.

The absence of lock flips in C08/C09 implies the intruder did not interact with the primary entrance lock, or the entry point was not secured by it (e.g., window, already unlocked door).

No subsequent re-entry or lingering presence is seen in C10-C17, supporting a 'hit-and-run' or brief trespass scenario rather than sustained occupation.

No corroborating evidence from door contacts or locks to confirm physical entry.

No theft or disturbance indicators (e.g., device tampering) are visible.

Could be explained by a pet or sensor malfunction.

Sensor Malfunction / Glitch: The occupancy sensors in the living room, master bedroom, and second bedroom experienced a temporary fault or environmental interference (e.g., sunlight, draft, pet) during C08, causing false 'occupied' readings that resolved themselves in C09.

The occupancy count in C08 (337) is high but not infinite, suggesting active sensing rather than a stuck-at value.

The immediate return to 'unoccupied' in C09 without any human activity logs suggests the event was isolated to the sensor layer.

Temperatures remain normal and stable throughout C08-C17, ruling out environmental causes like fire that might trigger multiple sensors simultaneously.

Requires assuming simultaneous failure or interference across three distinct rooms at the same time.

Does not account for potential real-world consequences if it wasn't a glitch.

The contrast between the high occupancy counts in C08 (337) and the immediate return to zero in C09 across multiple rooms.

The complete absence of DoorLock state changes or Contact Sensor triggers in both C08 and C09, which helps distinguish between an internal glitch/pet and an external intrusion through the main door.

Stable temperature profiles in C09-C17 confirming no secondary hazards (fire/leak) followed the C08 event.

Door contact sensor states and DoorLock history specifically for the C08 timeframe to rule out open-door entry.

Video surveillance footage or audio logs for C08 to visually/audibly confirm presence vs. sensor error.

Pet detection data or specific pet-related sensor tags to rule out animal movement.

Direct inspection of C08 to verify the 'occupancy spike' and determine if it represents a real event or sensor glitch.

Verification of DoorLock and Contact Sensor states during the C08 window to rule out intrusion.

Check for any smoke/gas/water leak alarms in C08.

The investigator's analysis relies heavily on Hypothesis A1 (Intrusion) and A2 (Sensor Malfunction) regarding an event in C08, but C08 is not included in the provided Focused Chunks. The current chunks (C09-C15) only show the aftermath (return to unoccupied).

Without seeing C08, we cannot confirm if the 'spike' was a transient glitch, a pet, or a real brief presence. Concluding safety based solely on post-event stability is insufficient for a composite-safety query that flags potential risks.

The risk of false alarm is high because the primary anomaly cited (the C08 spike) is unverified in the current evidence set. If C08 shows normal behavior, the entire 'intrusion/malfunction' narrative collapses.

Request C08 to validate the trigger event before finalizing the safety verdict.

The home is in a normal, unoccupied state with stable environmental conditions. The brief occupancy detection in the living room and master bedroom during midday (C08) represents a transient event (e.g., a resident passing through or checking something) that did not escalate into sustained presence or activity.

Temperature readings across all rooms (C00, C08, C17) remain within a comfortable, stable range (22-25°C) with no rapid spikes indicative of fire or equipment failure.

Occupancy sensors report 'unoccupied' for the vast majority of the monitoring period, including late night (C00, C17) and most of midday (C08).

No lock state changes or contact sensor triggers were recorded, indicating no unauthorized entry or exit events.

No smoke, gas, or water leak alarms were triggered in any chunk.

Does not fully explain the specific timing of the brief occupancy spike at 11:32 if it was truly transient, though this is minor.

Potential unsupervised activity or intrusion attempt indicated by a sudden, brief occupancy spike in multiple rooms without corresponding access control logs or subsequent sustained presence. The transition from 'unoccupied' to 'occupied' in the living room and master bedroom at 11:32, followed immediately by a return to 'unoccupied' by 12:00, suggests either a very short-duration visit or a system anomaly. However, given the lack of door lock/contact activity, this could also represent a false positive or a sensor glitch rather than a physical presence.

At 11:32:02 and 11:32:05, `living_room_occupancy` and `master_bedroom_occupancy` switch to 'occupied' (raw=1).

This change occurs shortly after a `balcony_door_contact` state change to 'false' (closed?) at 11:32:00, but there is no corresponding `entrance_door_lock` or `entrance_contact_sensor` activity to corroborate an entry via the main entrance.

By 12:00:00, both rooms revert to 'unoccupied'.

No other devices (kitchen, bathroom) show occupancy during this window, making simultaneous presence in living and master bedrooms less likely for a single person unless moving quickly between them.

The occupancy duration is very short (~28 minutes), which is ambiguous.

No explicit fault codes or alarm triggers are present.

Could be explained by a pet, a draft affecting a PIR sensor, or a temporary network glitch causing stale data updates.

Sensor malfunction or drift in occupancy sensors. The simultaneous activation of two distant occupancy sensors (living room and master bedroom) followed by a quick deactivation, without any corroborating motion in intermediate areas or access logs, may indicate a systemic issue with the occupancy sensing protocol or power fluctuation affecting these specific devices.

Simultaneous state change in `living_room_occupancy` and `master_bedroom_occupancy` at nearly identical timestamps (11:32:02 and 11:32:05).

Lack of corroborating evidence from other sensors (e.g., temperature changes consistent with human body heat, or movement in hallways/kitchen).

The rapid return to 'unoccupied' status suggests the trigger was not a sustained presence.

Single isolated event; does not meet the threshold for persistent malfunction without repetition.

Matter notes suggest interpreting booleans using transitions, and this is a valid transition sequence, just unusual in context.

The timestamped occupancy transitions in C08: `living_room_occupancy` and `master_bedroom_occupancy` switching to 'occupied' at 11:32:02/05 and back to 'unoccupied' by 12:00:00.

The absence of any `entrance_door_lock` or `entrance_contact_sensor` activity during the entire monitoring period, despite the occupancy changes suggesting potential presence.

Stable temperature readings across all chunks, ruling out thermal hazards like fire.

Logs for the `entrance_door_lock` and `entrance_contact_sensor` raw values to confirm they remained static and did not miss a brief open/close cycle.

Data from `kitchen_smoke_co_alarm` and `water_leak_detector` raw states to explicitly confirm no silent faults occurred.

Context on whether the household typically has pets or automated routines that might trigger occupancy sensors falsely.

No DoorLock state changes or contact sensor triggers are recorded in C09-C17, indicating no entry/exit events.

No smoke, gas, or water leak alarms were triggered.

The occupancy count in C08 (337) is high but not infinite, suggesting active sensing rather than a stuck-at value.

Verify if the occupancy spike in C08 was a transient glitch or sustained presence by checking intermediate chunks (C09-C16) for continued 'occupied' states.

Check for any door lock or contact sensor activity in the missing chunks to rule out unauthorized entry that might have been missed or logged outside the specific focus windows.

Confirm if the 'balcony_door_contact' state change at 11:32 correlates with any other security events in the surrounding timeframes.

The investigator correctly identified the anomalous occupancy spike in C08 but failed to check the subsequent hours (C09-C16) to determine if this was a persistent event or a transient glitch. Without these chunks, it is impossible to distinguish between a brief sensor error and a potential intrusion or unattended presence.

The current evidence is insufficient to conclude safety because the 'unoccupied' status in C17 does not prove what happened between 12:00 and 23:20. The gap in logging creates a significant blind spot for security analysis.

Risk of false alarm is medium because the anomaly relies on a single short-duration event without corroboration from access logs, but the lack of follow-up data prevents ruling out a real threat.

BA-04-FP: 传感器触发延迟导致顺序看似跳跃

客厅occupancy在阳台和主卧之间有触发（2秒时），移动路径合理

The kitchen cook surface was left active for approximately 43 minutes without direct evidence of occupancy in the kitchen, creating a potential fire hazard despite no alarm triggering.

Explanation: 1. **Event Sequence**: The kitchen cook surface was turned ON at 19:09:30 (C15) and remained ON until 19:52:00 (C16). This is a duration of ~43 minutes.

Explanation: 2. **Occupancy Gap**: During this entire window, there are no 'kitchen_occupancy' logs indicating presence in the kitchen. Occupancy is only confirmed in the living room and entrance, suggesting the occupant was not directly supervising the cooking area.

Explanation: 3. **Thermal Evidence**: The kitchen temperature rose from ~23°C to a peak of 26.88°C during this period, confirming heat generation consistent with the active cook surface.

Explanation: 4. **Risk Assessment**: While the temperature rise is moderate (suggesting controlled cooking rather than a blaze), the lack of direct supervision constitutes an 'unattended cooking' risk scenario. The transient 'None' reading at 19:53:00 is likely telemetry noise or minor interference upon turning off the stove, not a device fault, as it recovered immediately.

Explanation: 5. **Conclusion**: The combination of an active heat source and absence of local occupancy creates a plausible safety anomaly (unattended cooking), even though no fire occurred.

C15: kitchen_cook_surface OnOff = on at 19:09:30

C16: kitchen_cook_surface OnOff = off at 19:52:00

Absence of kitchen_occupancy events between 19:09 and 19:52

C16: Kitchen temp peaked at 26.88 C while cook surface was active

Review cooking habits to ensure the kitchen is monitored while the cook surface is active.

Consider enabling auto-shutoff features on the cook surface if available.

Verify smoke/CO alarm functionality periodically to ensure they would detect any future incidents.

Potential fire hazard in kitchen (high temp + cook surface)

Unusual lock state transitions at entrance

Occupancy patterns indicating presence during high-risk activities

C05: Shows morning activity with bathroom occupancy and kitchen light on, establishing baseline human presence.

Normal Evening Routine: Cooking and Cleanup. The temperature spike in the kitchen is a direct result of active cooking (cook surface ON), followed by normal cleanup activities (dishwasher ON). The transient 'None' reading was a brief sensor dropout that recovered immediately, consistent with minor telemetry noise or temporary obstruction, not a fault.

C15: Kitchen cook surface turned ON at 19:09:30.

C16: Kitchen temperature rose from 24.79 C to 26.88 C between 19:10 and 19:30, correlating with the active cook surface.

C16: Cook surface turned OFF at 19:52:00, after which temperatures began to stabilize/drop.

C16: Dishwasher turned ON at 20:02:00, indicating post-cooking cleanup.

C16: Kitchen temperature recovered to 25.51 C at 19:55:00 after the 'None' reading at 19:53:00.

Occupancy sensors show continuous presence in living_room and entrance throughout the evening (C15-C19), suggesting someone was home to monitor the kitchen.

Does not fully explain why the occupant left the immediate kitchen area for ~40 minutes while the stove was on, relying on the assumption that 'living room occupancy' implies general supervision rather than specific proximity.

Unattended Cooking Hazard. The cook surface was left active for approximately 43 minutes (19:09 to 19:52) without direct evidence of an occupant being in the kitchen. While the temperature rise was moderate, the lack of kitchen-specific occupancy data during this window, combined with the occupant's location likely being the living room/entrance, creates a risk scenario where a fire could have started unnoticed until it was too late.

C15: Kitchen light turned ON at 19:09:00, followed by cook surface ON at 19:09:30.

C15/C16: No 'kitchen_occupancy' events are recorded between 19:00 and 20:00. Only 'entrance_occupancy' and 'living_room_occupancy' are logged as occupied.

C16: Cook surface remained ON until 19:52:00. This is a duration of ~43 minutes.

C16: Kitchen temperature peaked at 26.88 C at 19:30:00, showing sustained heat generation.

C16: A 'None' reading occurred at 19:53:00, just after the stove was turned off, potentially indicating a momentary sensor failure due to heat or steam, or simply a gap in reporting during the transition.

No smoke/CO alarm events were triggered, but this does not rule out the hazard; it only confirms no fire broke out *yet*.

The temperature rise (max 26.88 C) is relatively modest for a house fire, suggesting the cooking was likely controlled or low-heat, reducing the probability of an actual emergency.

The 'None' reading is isolated and recovered, so it cannot be definitively linked to a hazardous event like a fire starting.

Living room occupancy suggests the household was present, even if not in the kitchen.

Sensor Telemetry Anomaly. The kitchen temperature sensor experienced a complete data loss ('None') at 19:53:00, immediately following the peak temperature and shortly after the cook surface was turned off. While it recovered, this single point of failure during a high-risk activity (cooking) represents a monitoring blind spot.

C16: At 19:53:00, `kitchen_temp_sensor` reports `TemperatureMeasurement.MeasuredValue = None`.

C16: At 19:55:00, the value recovers to 25.51 C.

C15: At 19:10:00, there was another brief anomaly where the value was reported as None before recovering to 24.79 C at the same timestamp (likely a logging artifact or rapid fluctuation).

Per Matter notes, a single transient 'None' that recovers is insufficient to declare a persistent sensor malfunction or fault. It may be a network glitch or temporary interference.

C15: Cook surface ON at 19:09:30 vs. absence of kitchen_occupancy logs until 20:00+.

C16: Sustained temperature rise (24.79 -> 26.88 C) while cook surface was ON.

C16: Cook surface OFF at 19:52:00, ending the unattended period.

C16: Transient 'None' reading at 19:53:00 coinciding with the end of the cooking event.

Direct confirmation of occupant location/proximity to the kitchen during 19:10-19:52 (e.g., audio detection or motion in the kitchen itself).

Smoke/CO alarm status logs to definitively rule out any combustion byproducts generated during the cooking process.

Detailed power consumption data for the cook surface to verify if it was set to high heat or simmering.

Verify if the 'None' reading at 19:53 was a transient glitch or persistent fault by checking C13 (pre-cooking) and C17 (post-cooking) for similar patterns.

Check for smoke/CO alarm logs in C16/C17 to definitively rule out combustion events during the unattended cooking window.

Confirm if the cook surface has an auto-shutoff feature or if the 'OFF' state at 19:52 was manual, which impacts the severity of the 'unattended' risk.

The investigator correctly identified the 'unattended cooking' scenario but relies heavily on the *absence* of kitchen occupancy logs as primary evidence. While valid, this is circumstantial without corroborating sensor data (smoke/CO) or power usage details.

The 'sensor_malfunction' hypothesis (A2) is flagged as high false-alarm risk because it rests on a single transient 'None' value that recovered immediately. Per Matter notes, this is insufficient to declare a device fault.

The investigation lacks the pre-event context (C13) to establish baseline telemetry quality and post-event stability (C17 is present but C13 is missing from focus). Without C13, we cannot determine if the 'None' reading is part of a recurring pattern or an isolated incident.

The conclusion of 'potential risk' is reasonable, but the evidence is not sufficient to distinguish between a genuine safety hazard (unattended stove) and a monitoring gap (missing occupancy log). Further refinement is needed to assess the likelihood of actual fire vs. just heat generation.

Normal evening cooking and cleanup routine with standard security behavior.

C16 shows kitchen temperature rising from 25.50 C to a peak of 26.88 C between 19:15 and 19:30, consistent with cooking activity.

Kitchen cook surface turns off at 19:52:00, followed by dishwasher activation at 20:02:00, indicating a logical post-meal cleanup sequence.

Kitchen temperature returns to baseline (~22-24 C) by 20:30 in C17, showing normal heat dissipation after the appliance was turned off.

Entrance lock operations in C05 (07:13) show a valid manual unlock followed by an auto-lock, which is standard secure behavior for leaving/entering.

Occupancy patterns show people present in living room and entrance during evening hours (C16/C17), suggesting supervision of the kitchen area.

The gap in kitchen occupancy data (no explicit 'kitchen_occupancy' sensor logs, only general room sensors) makes it difficult to confirm if someone remained in the immediate vicinity of the stove while it was active.

The 10-minute gap between turning off the cook surface and starting the dishwasher could imply a period of unattended heat or distraction, though no fire risk is evident.

Potential unattended cooking or delayed response to heat buildup in the kitchen.

In C16, kitchen temperature rises significantly (25.50 C -> 26.88 C) between 19:15 and 19:30 while the cook surface is presumably on (implied by temp rise and subsequent turn-off).

At 19:52:00, the cook surface is turned off, but there is no corresponding 'kitchen_occupancy' log confirming presence immediately before this action.

There is a telemetry dropout ('None') for the kitchen temperature sensor at 19:53:00, right after the cook surface is turned off, which could indicate a sensor issue or a momentary loss of monitoring capability during a critical transition.

The transition from cook surface off (19:52) to dishwasher on (20:02) leaves a 10-minute window where the kitchen state is monitored only by ambient temp, not direct appliance status or specific occupancy.

No smoke alarm or CO alarm events are recorded, which would typically trigger if unattended cooking led to a hazardous condition.

The temperature spike is moderate (max 26.88 C) and recovers quickly, lacking the exponential growth typical of a fire.

Living room and entrance occupancy remain high during this period, suggesting occupants were likely nearby, even if not explicitly logged in the kitchen.

Minor sensor telemetry instability in the kitchen environment.

In C16, the kitchen temperature sensor reports 'None' at 19:53:00, immediately following the cook surface being turned off.

This single dropout interrupts the otherwise regular 5-minute reporting interval of the temperature sensor.

While the value recovers at 19:55:00, the transient loss of data coincides with a change in appliance state (cook surface off), raising questions about sensor reliability during dynamic events.

It is a single isolated event; the sensor functions correctly before and after.

Matter notes specify that scaled values alone are not faults, and a single None value is insufficient to claim malfunction without repetition or contradiction.

C16: Kitchen temperature peak of 26.88 C at 19:30:00 correlates with cook surface usage.

C16: Cook surface turns off at 19:52:00, followed by a sensor 'None' reading at 19:53:00.

C16: Dishwasher activates at 20:02:00, establishing a timeline of kitchen activity.

C05: Entrance lock auto-locks successfully after manual unlock, demonstrating functional security hardware.

Direct 'kitchen_occupancy' sensor logs to confirm if a person was present in the kitchen during the cooking and shutdown phase.

Smoke detector or CO alarm status/logs to rule out any combustion byproducts or fire risks associated with the cooking event.

Detailed logs for the cook surface itself (beyond OnOff) to see if it had any error states or automatic shut-off triggers.

C15: Kitchen cook surface turned ON at 19:09:30.

C16: Cook surface turned OFF at 19:52:00, after which temperatures began to stabilize/drop.

C16: Dishwasher turned ON at 20:02:00, indicating post-cooking cleanup.

C16: Kitchen temperature recovered to 25.51 C at 19:55:00 after the 'None' reading at 19:53:00.

C15: Kitchen light turned ON at 19:09:00, followed by cook surface ON at 19:09:30.

C16: Cook surface remained ON until 19:52:00. This is a duration of ~43 minutes.

C16: Kitchen temperature peaked at 26.88 C at 19:30:00, showing sustained heat generation.

C16: At 19:53:00, `kitchen_temp_sensor` reports `TemperatureMeasurement.MeasuredValue = None`.

C16: At 19:55:00, the value recovers to 25.51 C.

Verify if the cook surface was actually ON during the temperature rise (check C15 for 'On' event or state before 19:15).

Check for smoke/CO alarm activation events in C16/C17 to rule out fire/smoke generation.

Confirm if the 'None' reading at 19:53 is a sensor dropout or a valid null state, and check surrounding chunks for repeated faults.

Assess if the 10-minute gap between cook surface OFF and dishwasher ON constitutes an unattended hazard given the occupancy data.

The investigator correctly identifies the temperature spike and appliance sequence but relies heavily on inference ('implied by temp rise') rather than direct evidence of the cook surface being ON.

The 'unattended cooking' hypothesis is weak because there is no explicit confirmation the stove was active during the peak heat, nor any alarm triggers. The temperature rise (25.5->26.88 C) is modest and consistent with ambient heating from cooking, not necessarily a fire hazard.

The 'sensor malfunction' hypothesis is flagged as high false-alarm risk because it rests on a single transient 'None' value that recovers immediately, which is insufficient for a fault conclusion per Matter notes.

Missing context: We need to see when the cook surface turned ON (likely in C15) to establish the full timeline. Without knowing how long it was on, we cannot assess 'unattended' risk accurately.

The investigation drifts slightly into debating telemetry quality (sensor dropout) rather than focusing on the safety outcome (was there a fire? was anyone present?).

Request adjacent chunks C15 (pre-cooking setup) and C18 (post-dishwasher cleanup) to complete the behavioral sequence and verify appliance states.
