FG-01-FP: 煲汤/慢炖（正常长时间开灶）

温度上升后稳定（不持续飙升），住户定期回来检查，烟雾传感器未触发

The home is currently safe; the transient sensor glitch at 19:44:00 was a temporary connectivity issue that fully recovered within one minute, and no security breaches or equipment failures were detected.

Explanation: The kitchen temperature sensor reported 'None' at 19:44:00 immediately following a sequence of appliance state changes (cook surface off, window contact open), which initially raised suspicion of a fault or environmental hazard.

Explanation: However, the sensor recovered and reported valid data (26.38 C) exactly 60 seconds later, with subsequent readings showing a stable cooling trend consistent with ambient conditions, indicating the device remained functional.

Explanation: No explicit DeviceFault, Alarm, or OperationalError events were logged during this incident, and the coincidence of events with other sensors suggests a momentary network latency or power fluctuation rather than a hardware failure or security breach.

kitchen_temp_sensor reported MeasuredValue = None at 2026-06-01T19:44:00, followed by recovery to 26.38 C at 2026-06-01T19:45:00.

Absence of any system-wide alarms or fault codes in the logs surrounding the glitch event.

Monitor the kitchen temperature sensor for recurring 'None' values to rule out intermittent hardware degradation.

Verify the configuration of the kitchen window contact to ensure it is correctly linked to the alarm system if intended for intrusion detection.

C12 provides context on the high alarm count (27) occurring during evening occupancy, helping verify if the anomalies were isolated incidents or part of a broader system instability affecting the living area.

Transient network latency or momentary power fluctuation caused a single data packet loss for the kitchen sensor, which fully recovered within seconds without indicating hardware failure.

At 19:44:00, kitchen_temp_sensor reported 'None' immediately after cook surface turned off and window contact changed state.

By 19:45:00 (60 seconds later), the sensor reported a valid value of 26.38 C, showing immediate recovery.

No explicit 'DeviceFault', 'Alarm', or 'OperationalError' events were logged in the surrounding timeframes.

The sensor continued to report stable, physically plausible temperatures (dropping from ~26C to ~22C) throughout the evening as ambient conditions cooled.

The coincidence of the glitch with other sensor events (window contact, cook surface) suggests a potential correlation, though causality is not proven.

Kitchen window contact reported 'false' (open) at 19:43:30 represents a legitimate opening event by an occupant, not a security breach, given the subsequent locking sequence and lack of intrusion alarms.

At 19:43:30, front_door_contact and kitchen_window_contact both reported false states simultaneously.

Following this, at 21:55:37, the front door lock automatically locked and the front door contact returned to true (closed).

Occupancy sensors indicate humans were present in the living room during these times.

No security system alarm was triggered during the window opening or door closing sequence.

If the window remained open while cooking, there is a theoretical fire risk if the cook surface had been active, but logs show the cook surface turned off at 19:43:00 *before* the window opened.

Potential sensor malfunction or environmental interference affecting the kitchen temperature sensor, indicated by a transient data loss event ('None') coinciding with appliance activity.

At 19:43:00, the kitchen_cook_surface turned off.

At 19:43:30, the kitchen_window_contact reported 'false' (open).

At 19:44:00, the kitchen_temp_sensor reported 'None' instead of a value.

This pattern of consecutive state changes followed by a null reading is unusual compared to the stable readings seen before and after.

The sensor recovered fully within one minute (by 19:45:00), reporting values consistent with the cooling trend.

There are no explicit fault codes or alarm events generated by the system.

The 'None' value could be explained by a temporary connectivity drop rather than a device fault.

The specific timestamp sequence: Cook Surface OFF (19:43:00) -> Window Open (19:43:30) -> Temp Sensor None (19:44:00) -> Recovery (19:45:00). The proximity of these events links them temporally, but the lack of persistent error states or alarms keeps the 'transient glitch' hypothesis strong against 'hardware failure'.

Absence of any 'DeviceFault' or 'SystemAlarm' events in the entire log despite the occurrence of the 'None' reading.

Raw network heartbeat logs to confirm if the 'None' value corresponds to a dropped packet vs. a sensor read failure.

Explicit configuration for the kitchen window contact (is it linked to the alarm system? If so, why no alarm triggered when it went 'false'?).

Historical data on the frequency of 'None' values for this specific sensor to determine if this was an isolated incident or part of a recurring pattern.

Verify kitchen window contact configuration (alarm linkage) to definitively rule out security breach hypothesis.

Check raw network heartbeat logs around 19:44:00 to distinguish between packet loss and sensor read failure.

The investigator correctly interpreted the Matter-scaled temperature values (e.g., 2750 -> 27.5°C), avoiding the false-alarm risk of treating them as literal impossible temperatures.

Evidence is sufficient to conclude the 'None' reading at 19:44:00 was a transient glitch rather than a persistent hardware fault, given the immediate recovery and lack of explicit error events.

The sequence of events (Cook off -> Window open -> Sensor glitch) appears coincidental; no causal link to fire or intrusion is established.

While the current data supports a conservative 'normal operation with transient noise' verdict, noting the missing window alarm configuration and network logs adds necessary context for future audits without changing the immediate safety assessment.

Verify network connectivity/heartbeat logs to distinguish between sensor hardware failure and temporary packet loss causing the 'None' value.

Check for explicit device fault or alarm events in the logs surrounding the 19:44:00 timestamp to confirm a hard failure vs. transient glitch.

Analyze C13 to determine if the sensor recovered fully or entered a persistent error state after the dishwasher cycle began.

The Investigator correctly interpreted the raw value 2750 as ~27.5°C (per Matter notes) rather than an impossible 2750°C, avoiding a false-alarm risk regarding temperature magnitude. However, they flagged A1 as a potential malfunction due to the 'None' value.

Evidence is insufficient because the single occurrence of 'None' followed by immediate recovery does not definitively prove a hardware fault; it could be a momentary network timeout or power blip. The lack of explicit 'Fault' event logs creates ambiguity.

Chunk C13 is required to see the post-recovery behavior and ensure the system stabilized before the dishwasher started heating, which would validate if the sensor was robust enough to handle the thermal load.

Recommend conservative stance: Do not classify this as a confirmed safety breach yet. Treat as 'investigating sensor reliability' until C13 confirms stability or reveals a pattern of failures.

活动从卧室开始（住户起床），路径合理（卧室→客厅→厨房→卧室），最终回到卧室

The household is in a safe state; the temperature spike was caused by normal cooking activity which was properly managed by active HVAC cooling and device shutdown.

Explanation: Temperature analysis confirms that the kitchen temperature spike (reaching ~27.17°C) occurred during evening hours when residents were present and coincided exactly with the activation of the kitchen cook surface at 18:59:30.

Explanation: System behavior demonstrates effective safety response: the living room AC activated shortly before the heat load increased, maintained low temperatures to protect the home environment, and the cook surface was turned off at 19:48:00, leading to rapid stabilization of kitchen temperatures to baseline levels (~22.6°C).

Explanation: No fault indicators were found; transient sensor 'None' readings are identified as reporting gaps rather than failures, and no smoke alarms or fire events were triggered during the incident.

Sequence of events: Cook Surface ON (18:59:30) -> Temp Spike (18:30-18:59) -> AC Active (18:21) -> Cook Surface OFF (19:48:00) -> Temp Stabilization (19:50+).

Kitchen temperature returned to pre-cooking baseline (~22.6°C) within minutes of turning off the appliance, indicating no residual heat hazard.

Occupancy logs show consistent presence of residents in the entrance and living areas throughout the event, ruling out unauthorized entry.

Continue monitoring standard environmental parameters.

Ensure kitchen ventilation fans are used regularly during future cooking sessions to minimize ambient heat buildup.

综合所有信息，判断家庭当前的安全状况，指出任何潜在风险。

Normal evening cooking activity with active HVAC cooling and subsequent stabilization.

At 18:59:30, kitchen_cook_surface turned ON while occupants were present in the living room/kitchen area.

Kitchen temperature spiked from ~23°C to a peak of 27.17°C (raw=2717) between 18:25 and 18:30, coinciding with high ambient heat load from cooking.

Living room AC was activated at 18:21:18 (SystemMode=3) and maintained low temperatures (~22.9-23.0°C) throughout the event.

Cooking surface was turned OFF at 19:48:00, followed by rapid cooling of the kitchen sensor back to baseline levels (~22.7°C) by 19:50.

No alarm events or fault codes were generated during the temperature excursion.

The temperature spike was significant (+4°C above baseline), though consistent with unvented cooking in an enclosed space without immediate extraction.

Sensor data briefly went 'None' at 19:00:00 and 19:49:00; however, values resumed immediately, suggesting a transient reporting gap rather than a permanent failure.

Correlation of high occupancy in entrance/living room with the activation of cooking surfaces and AC cooling suggests planned resident behavior rather than intrusion or malfunction.

The specific sequence of 'Cook Surface On' -> 'Temp Spike' -> 'AC Active' -> 'Cook Surface Off' -> 'Temp Stabilization' forms a coherent causal chain typical of normal home usage.

Status of kitchen ventilation fans or range hood operation during the cooking window (18:59 - 19:48) would confirm if heat buildup was mitigated or exacerbated.

Investigator correctly interpreted Matter-scaled temperature values (e.g., raw=2717 as 27.17°C), avoiding the high false-alarm risk of treating them as literal impossible temperatures.

The causal chain established in the Investigator Output (Cook Surface On -> Temp Spike -> AC Active -> Cook Surface Off -> Stabilization) is robust and supported by the provided chunks C15 and C16.

Transient 'None' sensor readings were correctly identified as reporting gaps rather than device failures or anomalies.

No safety risks were found; the situation represents normal residential cooking activity with effective HVAC response.

All relevant temporal windows for the incident are covered; no additional chunks are needed to reach a definitive conclusion.

CH-04-FP: 家长在玄关操作门锁

The home environment is safe with no evidence of intrusion, fire risk, or device failure; observed events align with normal occupancy patterns and transient communication glitches.

Explanation: Security integrity is confirmed: Manual door unlocks occurred only when entrance occupancy was active (C06, C18), and the end-of-day auto-lock sequence executed correctly after lights and AC were turned off (C27).

Explanation: Fire and cooking risks are mitigated: The cook surface was used briefly in the morning (C06) followed by immediate shutdown, and subsequent temperature readings remained stable within normal residential ranges (approx. 23-25°C).

Explanation: Sensor reliability is verified: Intermittent 'None' readings from the kitchen temperature sensor were immediately followed by valid data points, indicating a transient network glitch rather than a stuck sensor or malfunction.

Explanation: Occupancy and environmental logic hold: All room occupancies show logical transitions consistent with daily living activities, and there are no signs of unattended cooking or unsafe temperatures.

C06 & C18: LockOperation events source=Manual coincide with OccupancySensing.Occupancy=occupied, ruling out unauthorized entry.

C06: Kitchen_temp_sensor recovered to valid values (e.g., 25.18 C) immediately after reporting None, refuting hardware failure.

C27: Standard secure-down automation completed successfully with lights/AC off and door locked automatically.

Monitor kitchen temperature sensor signal strength periodically to ensure transient gaps do not become frequent.

No immediate intervention required; system status is nominal.

C27 shows the standard end-of-day automation sequence (locking doors, closing windows/curtains), providing a baseline for normal 'safe' behavior to compare against anomalies.

The home security system is functioning correctly with automated secure-down routines and manual interventions occurring only when occupants are present.

C27 shows a standard end-of-day sequence: lights off, AC off, curtains closed (window coverings fully retracted), followed immediately by an 'Auto' lock operation and door contact closing.

C06 and C18 show 'Manual' lock unlocks occurring while entrance occupancy was confirmed as 'occupied', indicating authorized user access rather than breach attempts.

Temperature readings across all sensors remain stable and within normal residential ranges (approx. 22-25°C) throughout the day.

Occupancy patterns show logical transitions between rooms consistent with daily living activities.

None significant; the observed behaviors align perfectly with expected smart-home automation logic and human behavior.

Kitchen temperature sensor intermittently failing to report data during peak usage is a transient communication glitch or temporary calibration delay, not a permanent device fault.

In C06, `kitchen_temp_sensor` reports `None` at 07:11:05 and 07:21:00, but immediately resumes reporting valid values (e.g., 25.18 C at 07:15:00 and 25.06 C at 07:20:00).

The surrounding context (cook surface on/off, other room temperatures stable) suggests the environment is safe, implying the sensor hardware is likely functional but experiencing brief packet loss or processing delays.

While recovery is quick, repeated gaps could indicate a marginal connection issue that warrants monitoring, though no explicit error state was logged.

The immediate resumption of valid temperature readings after `None` events in C06 rules out a stuck sensor or total failure.

The correlation of `LockOperation` events with `Occupancy = occupied` in both morning (C06) and afternoon (C18) chunks confirms legitimate user activity.

The strict sequencing of 'off' commands for lights/AC followed by 'Auto' lock engagement in C27 demonstrates robust automation integrity.

Historical logs for previous days to establish baseline frequency of kitchen sensor `None` values.

Signal strength metrics or network status for the kitchen sensor to rule out interference causing intermittent drops.

Historical baseline for kitchen sensor `None` events (to distinguish transient glitch from recurring hardware fault).

Network signal strength metrics for the kitchen sensor (to rule out interference).

The investigator correctly interpreted the Matter-scaled temperature values (e.g., raw=2518 = 25.18°C), avoiding false alarms regarding impossible temperatures.

The analysis of the 'Manual' lock unlock at 07:14:35 is sound; it occurred while occupancy was confirmed as 'occupied', strongly indicating authorized user activity rather than a breach.

The kitchen temperature sensor's intermittent `None` readings are supported by immediate recovery in subsequent logs, suggesting a transient communication issue rather than a critical safety failure. However, without historical data to determine frequency, this remains a low-priority monitoring item rather than an active alarm.

No evidence suggests fire risk, unauthorized entry, or system malfunction requiring immediate intervention. The current evidence supports a conclusion of 'Normal/Safe' with minor operational notes.

CH-01-FP: 孩子生病请假在家（家长陪护）

家长也在家（多个房间有活动），不只是儿童房，说明有成人陪护

Current evidence indicates normal household activity with no active safety threats, though critical life-safety device states and continuous lock monitoring are unverified.

Explanation: Temperature data across all rooms (C05, C14, C19, C20, C23) remains within safe residential ranges (approx. 22.5°C - 25.2°C), showing logical cooling trends when the AC was activated in the evening (C20/C23).

Explanation: The temporary 'None' readings from the kitchen temperature sensor were transient and immediately followed by valid values after a cook surface operation, indicating a momentary communication glitch rather than a sensor malfunction or stuck state.

Explanation: Occupancy patterns show consistent human presence throughout the day, and the single door unlock event at 18:03 correlates directly with entrance occupancy changes, confirming authorized entry without signs of intrusion or tailgating.

Explanation: However, the analysis cannot definitively rule out fire, carbon monoxide, water leak, or unauthorized entry during gaps where these specific devices were not logged or where lock states between events are unknown.

All recorded temperatures fall well below hazardous thresholds.

Kitchen sensor recovered from 'None' to valid readings immediately after appliance use.

Door unlock event at 18:03 matches subsequent occupancy trigger, indicating legitimate access.

No explicit alarm, fault, or intrusion events were recorded in the provided log chunks.

Verify the current armed/disarmed and operational status of Smoke/CO detectors and Water Leak sensors as they were absent from logs.

Review full-door-lock state enumeration history to ensure the front door remained secured during periods of high occupancy where no lock transition events were logged.

Standard residential daily routine with normal HVAC cycling and sensor readings within safe operating ranges.

Temperature readings consistently fall between 22.5°C and 25.2°C across all rooms, well within normal comfort and safety limits.

Occupancy patterns show logical progression: entrance sensors trigger occupancy in common areas (living/dining/kitchen), while bedrooms show mixed states consistent with family members moving between spaces.

HVAC activation (Living Room AC turned ON at 18:03) correlates immediately with a temperature drop from ~23.15°C to ~22.7°C by 20:00, indicating effective climate control.

No explicit fault events, alarm triggers, or impossible state transitions are recorded in the logs.

Absence of data for Smoke/CO detectors and Water Leak detectors prevents full verification of fire/flood safety systems.

DoorLock state transitions are sparse; only one unlock event is visible, leaving the status during other occupancy periods unverified.

Kitchen_temp_sensor returning 'None' values at 06:52:00 and 06:53:03 was followed immediately by the cook surface turning ON and subsequent valid temperature readings (24.96°C, 24.95°C) shortly after, ruling out a permanent sensor failure.

The correlation between front_door_lock unlocking (raw=2) and entrance_occupancy becoming occupied confirms authorized entry rather than an intrusion attempt.

Smoke_CO_Alarm and Water_Leak_Detector state readings are absent from all provided chunks (C05, C14, C19, C20, C23).

Continuous DoorLock.LockState enumeration (not just events) is needed to verify if the door remained secured during times when entrance occupancy was high but no lock operation event occurred.

Data from outside the sampled time windows (specifically late night/morning before C05 and after C23) might contain alarm events that did not occur during these active hours.

Verify Smoke_CO_Alarm and Water_Leak_Detector states (absent in all provided chunks C05, C14, C19, C20, C23).

Confirm DoorLock.LockState enumeration values during high occupancy periods where no unlock event was logged to rule out unauthorized entry.

Cross-reference 'alarmish_count' spikes mentioned in Triage Output with actual alarm events in the full log set.

The current evidence is sufficient to rule out immediate thermal hazards or sensor failures based on temperature ranges and recovery from 'None' values.

However, safety assessment cannot be finalized without data from critical life-safety devices (Smoke/CO/Water) which are explicitly missing from the analyzed chunks.

Door lock state continuity during active occupancy windows remains unverified; relying solely on transition events creates a blind spot for potential tampering.

Chunks C19 and C20 cover evening hours when occupants were present but lack any fault/alarm records; these must be fully reviewed to confirm system health before concluding 'Normal' status.

Normal household activity with active HVAC climate control and no security breaches.

Occupancy sensors show consistent presence in living, kitchen, kids, and master bedrooms during morning (C05) and afternoon/evening (C23) windows, indicating family members are present.

Temperature readings fluctuate logically based on time of day: rising from ~24.8°C in the morning to ~25.1°C mid-day, then dropping significantly to ~22.6°C in the evening (C23), suggesting a functional heating/cooling system responding to occupancy or setpoints.

Cooking activities occurred (kitchen_cook_surface OnOff transitions) while occupants were present, which is standard behavior.

No explicit fault events, alarms, or impossible state transitions were recorded in the logs.

The evening temperature drop (~22.6°C) might be slightly cool for some comfort standards but is within normal operational ranges for many climates.

Temporary sensor data gaps due to environmental interference or network latency, not device failure.

In C05, `kitchen_temp_sensor` reports `None` at 06:52:00 and 06:53:03 immediately following cooking surface activation. This coincides with high thermal load (cooking), which can temporarily saturate sensors or cause packet loss.

Sensor values resume reporting normally shortly after these gaps without any explicit 'fault' or 'alarm' event being logged by the device itself.

While likely benign, repeated nulls could indicate a marginal connection issue if this pattern persisted throughout the log.

The absence of any 'SystemFault', 'Alarm', or 'OperationalState=unavailable' events despite temporary sensor nulls.

The logical correlation between cooking events and subsequent temperature spikes, followed by normalization once cooking ceased.

Consistent occupancy states matching expected daily routines (morning wake-up, daytime activity, evening gathering).

Data from smoke/CO detectors and water leak sensors is absent from the provided chunks; their status cannot be verified.

Current DoorLock state (locked/unlocked) and door contact sensor values are not explicitly logged in the focused chunks, though entrance occupancy is tracked.

DoorLock.LockState transitions (locked/unlocked) to verify security integrity during occupancy changes.

Smoke_CO_Alarm and Water_Leak_Detector state readings (present in target list but absent in provided chunks).

Verification of 'None' values in C05 as sensor faults vs. valid data gaps without explicit fault events.

Cross-checking entrance occupancy spikes with door lock status to rule out unauthorized entry attempts.

The investigation correctly identified the temperature scaling (e.g., 2466 = 24.66°C) and avoided false alarms regarding impossible temperatures. The hypothesis that null values in C05 are benign is reasonable given the lack of fault logs, though conservative verification is needed.

Critical evidence is missing: No DoorLock states or Safety Sensor (Smoke/CO/Water) data were found in the selected chunks (C05, C14, C23), despite these being high-priority targets for a 'composite-safety' analysis. This creates a significant blind spot for fire, flood, and intrusion risks.

To complete the safety assessment, chunks covering potential alarm events (often occurring outside standard daily activity windows) and specific security device interactions must be retrieved. Chunks C19-C20 are suggested based on typical log distribution patterns for evening/night safety events if not covered in C23.

Current evidence supports a 'Normal' verdict for climate and occupancy, but cannot fully confirm 'Safe' status due to missing security system data.

Current data supports normal household operations with no confirmed security breaches or device faults, though critical security logs (door lock access details and safety device armed status) are missing to fully rule out low-probability risks.

Explanation: Temperature sensors function correctly: Matter-scaled values (e.g., 2466 = 24.66°C) show logical correlations between occupancy changes and thermal loads (e.g., kitchen temp rising after cooktop activation), with no evidence of sensor drift, stuck values, or impossible states.

Explanation: Occupancy patterns align with typical daily routines: Houses transition from unoccupied at night (C00-C01) to occupied in the morning (C05) and evening (C28), with consistent actuator responses (lights/window covers turning on/off upon detection).

Explanation: No direct evidence of failure or intrusion exists: While C05 contains '5 door lock state flips,' the raw logs do not explicitly label these as unauthorized; similarly, no alarms were triggered for smoke/CO/water leaks despite active cooking and occupancy. Without explicit 'unauthorized' flags or alarm events, a fault conclusion is premature.

Explanation: Transient glitches are resolved: The single instance of 'None' value in the kitchen temperature sensor (06:33:08) recovered immediately to valid data, indicating a temporary communication issue rather than a hardware malfunction.

Correlation between 'kitchen_cook_surface ON' event and subsequent temperature rise confirms sensor logic integrity.

Absence of explicit 'alarm' or 'fault' events across all chunks, including high-activity periods.

Rapid recovery of transient 'None' sensor reading without persistent deviation.

Consistent occupancy-to-actuator timing (e.g., light turns on within seconds of occupancy detection).

Verify if the 5 door lock state transitions in C05 corresponded to authorized entry/exit by cross-referencing user identity logs.

Confirm the current 'Armed' status of smoke, CO, and water leak detectors via the system UI or API.

Monitor future occurrences of 'None' sensor values to ensure they remain isolated transient events.

Household operations are within normal parameters. Temperature sensors accurately reflect HVAC performance and occupancy-induced thermal loads. Occupancy patterns align with typical daily routines (sleep, wake, work, return). No device faults or security breaches detected.

C00-C01: Nighttime temperatures stable (~22-23°C) while home is unoccupied; gradual rise during morning (C05) correlates perfectly with occupants entering rooms (master_bedroom, kids_room) and turning on lights/appliances.

C16: Afternoon activity shows consistent temperature distribution (~24°C) across occupied rooms (kids, master, entrance, dining), with no anomalous hot/cold spots suggesting HVAC failure.

C28: Evening occupancy returns all rooms active; temperatures stabilize around 22.5-22.7°C, consistent with evening cooling cycles.

C05: Kitchen surface turned ON at 06:32:38 immediately followed by temperature readings in the kitchen rising from ~24.8°C to ~25.0°C, demonstrating expected sensor response.

No explicit fault events, stuck values, or impossible state transitions observed in any chunk.

Lack of explicit armed/disarmed status for smoke/CO/water detectors prevents confirming active protection status, though no alarms were triggered.

The precise correlation between occupancy state changes (e.g., master_bathroom_occupancy transitioning to 'occupied' at 06:24) and subsequent actuator commands (light ON at 06:24, then OFF at 06:32) and environmental changes (kitchen temp rise after cooktop activation) confirms system integrity and logical consistency.

Transient 'None' value for kitchen_temp_sensor at 06:33:08 occurred exactly when the cooktop was active and shortly after a light transition, but the sensor recovered to valid data (24.85°C) at 06:35:00, indicating a temporary communication glitch rather than a hardware fault.

Explicit status of safety devices (smoke, CO, water leak) - specifically whether they are currently 'Armed' or 'Disarmed'.

Access logs for the DoorLock to verify if the 5 lock_state_flips mentioned in structured signals correspond to authorized entry/exit or potential unauthorized access attempts.

Historical baseline temperatures to definitively rule out seasonal anomalies for the current readings (though current variance looks normal).

Verify DoorLock state transitions (5 flips mentioned in Triage) against timestamps to rule out unauthorized access.

Confirm armed/disarmed status of safety devices (smoke/CO/water leak).

Review C28 late-night chunk for occupancy patterns and temperature stability during unoccupied periods.

The investigator correctly interpreted Matter-scaled temperature values (e.g., 2466 = 24.66°C), avoiding the false-alarm risk of treating them as literal degrees. No high-risk misinterpretations found.

Current evidence strongly supports normal operation regarding HVAC and sensor logic (transient 'None' value recovered quickly). However, critical security data is missing.

The Investigator Output explicitly lists 'Access logs for the DoorLock' as missing information but fails to include it in the `needs_more_chunks` list. Chunk C05 contains the relevant door lock flip events; C28 is needed for late-night baseline verification.

The analysis cannot be finalized without verifying if the 5 door lock state flips in C05 were authorized or indicate a breach.

The home environment is operating normally with stable thermal regulation, consistent occupancy patterns matching human activity cycles (morning wake-up, afternoon routine, evening return), and no active device faults.

Temperature readings across all rooms remain within a narrow, realistic band (22.5°C - 25.2°C) appropriate for summer weather and HVAC operation.

Occupancy transitions align logically: Empty at 06:30 (after waking), populated during the day (15:00-15:45), and fully occupied again in the evening (23:30+).

No 'None' values appear in temperature streams after an initial transient null; sensors are actively reporting.

Lock state flips (count=5) occur without contradiction to occupancy data (e.g., door lock state changes do not contradict room occupancy status which relies on presence detection).

Actuator commands (lights turning on/off, cook surface activating) show expected state changes immediately.

Absence of explicit 'fault' or 'alarm' events does not guarantee hardware perfection, only that the system hasn't triggered its internal error states.

Consistent correlation between high occupancy counts (entrance/dining/kitchen active) and slight temperature fluctuations, indicating normal heating from human activity rather than sensor drift.

The single instance of `kitchen_temp_sensor` returning `None` at 06:33:08 was followed by valid readings at 06:35:00, ruling out a permanent sensor failure.

All boolean states (Occupancy, OnOff) transition smoothly without holding impossible values (e.g., Occupancy=1 while all lights off in a dark room where someone claims to be present, though lighting states vary by room usage).

Door lock specific event logs (which user accessed, time of access, duration open) to verify if the 5 'lock_state_flips' represent normal entry/exit or potential tampering.

Explicit alarm logs for smoke, CO, or water leak detectors to confirm they are armed and monitoring, as these were not explicitly triggered in the provided chunks.

Historical baseline temperatures to definitively rule out minor HVAC drift if the house has been unusually hot/cold recently.

Verify smoke/CO/water leak detector armed status and recent alarm logs (explicit events missing from provided chunks).

Correlate door lock state transitions with specific access IDs to distinguish normal entry/exit from potential tampering.

Check historical baseline temperatures to confirm current thermal readings are within expected seasonal ranges.

Review actuator command logs for any stuck states or failed execution attempts during the active occupancy periods.

The investigator correctly interpreted scaled temperature values (e.g., 2466 = 24.66 C), avoiding the 'false-alarm' pitfall of treating raw integers as literal degrees.

Current evidence focuses heavily on environmental stability and occupancy patterns but lacks explicit security system telemetry (alarms armed/disarmed) and granular access logs.

The single sensor null event was transient and recovered; no immediate hardware fault conclusion is warranted based on available data.

Adding early morning chunks (C00-C01) would provide a complete picture of the night-to-morning transition, verifying if the system behaves consistently before the family wakes up and interacts with devices.

Without explicit alarm event logs, we cannot definitively rule out a silent failure mode in safety detectors (smoke/CO/water).

发生在正常午睡时段（12:30-14:00），最后活动在卧室且灯已关/窗帘已关

The bedroom temperature dropped to approximately 21.6°C while the elderly resident was present, potentially posing a thermal comfort or health risk.

Explanation: Analysis of Chunk C19 reveals that between 20:13 and 21:00, the bedroom temperature sensor recorded values as low as 21.62°C (at 20:20:00) and 21.54°C (at 20:30:00).

Explanation: Despite these low readings, occupancy sensors in the bedroom (and other rooms) consistently reported 'occupied' (raw=1), confirming the elderly resident was active in the environment during this period.

Explanation: While the kitchen maintained warmer temperatures (~22.7°C), the significant drop in the bedroom below standard comfort thresholds for an elderly person constitutes a valid safety concern requiring verification of heating systems or thermostat settings.

Explanation: No evidence of device failure (like stuck sensors) was found; the sensor recovered to normal ranges in subsequent chunks (C23), ruling out persistent malfunction.

[2026-06-03T20:20:00] bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 21.62 C

[2026-06-03T20:20:00] bedroom_occupancy | OccupancySensing.Occupancy = occupied (raw=1)

Verify the operation of the bedroom heating system or thermostat.

Check if the resident feels cold or requires additional bedding/warmth.

Consider adjusting the night-time setpoint to ensure ambient temperatures remain above 22°C for vulnerable residents.

C23: The final chunk shows reduced event counts and stable low temperatures, helping confirm if the temperature issue is resolved or persistent.

The home environment is operating within normal safety parameters for an occupied residence. Temperature readings are consistent with indoor comfort levels (approx. 22-25°C), and occupancy sensors confirm continuous presence of the resident in key areas.

C04: Kitchen temperature fluctuates normally between 24.79°C and 25.20°C while occupied.

C05: Morning temperatures rise gradually to ~25°C, consistent with heating cycles or sunlight exposure during daylight hours.

C19: Nighttime temperatures stabilize around 21.6-22.7°C, which is a healthy range despite being slightly cooler than daytime.

C23: Late-night readings show stable temperatures (~22.6°C) with no sudden drops or spikes.

Locking sequence in C04 (06:51:06-06:51:13) shows a complete and successful manual unlock followed by auto-lock upon door closure.

A single null value ('None') was recorded for the kitchen sensor at 06:27:00 in C04, though it recovered immediately.

Nighttime temperatures (C19) are on the lower end of the comfortable range (21.6°C), which could pose a minor risk if the resident is elderly and immobile, but not necessarily an acute emergency.

Transient Sensor Data Loss Event.

C04: At 2026-06-03T06:27:00, the `kitchen_temp_sensor` reports `TemperatureMeasurement.MeasuredValue = None`, deviating from the standard format seen in all other entries (e.g., '24.88 C').

C04: This event occurs immediately after a reading of 24.79°C and is followed by a recovery reading of 24.85°C at 06:30:00.

Context: The kitchen was occupied (raw=1) at the time of the error, suggesting the issue is internal to the sensor or communication link rather than a lack of signal due to vacancy.

The duration of the failure was very short (<3 minutes), and the sensor self-recovered without requiring external intervention.

No subsequent anomalies occurred in C05, C19, or C23, suggesting this may have been a momentary glitch (e.g., radio dropout) rather than a persistent hardware fault.

Potential Thermal Stress Risk for Vulnerable Resident.

C19: Between 20:13:00 and 21:00:00, bedroom temperature dropped to 21.62°C (at 20:20:00).

C19: Living room temperature remained similarly low (22.58°C - 22.71°C) during the same period.

Context: While not freezing, temperatures below 21°C can be uncomfortable or hazardous for elderly individuals, especially if they have reduced mobility preventing them from seeking warmer zones or adjusting thermostats.

Temperatures were not critically low; modern homes often drop to this level overnight without causing harm.

Occupancy data confirms the resident was active and present in the rooms (bathroom lights on, movement detected), mitigating risks associated with isolation.

C04 timestamp 06:27:00 showing 'MeasuredValue = None' instead of a numeric value, indicating a specific data packet loss or sensor hiccup.

C19 timestamp 20:20:00 showing the lowest recorded temperature (21.62°C) coinciding with full house occupancy, highlighting environmental conditions relative to occupant status.

Historical baseline temperatures to determine if the nighttime drop in C19 is abnormal for this specific climate/season.

Resident's specific health profile (e.g., respiratory issues, mobility limitations) to accurately assess the severity of the 21.6°C ambient temperature.

Logs regarding the specific model of the kitchen sensor to rule out known firmware bugs causing intermittent 'None' returns.

Transient Sensor Data Loss Event.

Historical baseline temperatures to confirm if the ~21.6°C night reading is abnormal for this season/location.

Specific health profile of the elderly resident (mobility limits, respiratory issues) to weigh the thermal risk accurately.

The investigator correctly interpreted the Matter scaling (raw=2488 = 24.88°C), avoiding the 'impossible temperature' false-alarm risk associated with treating raw values as literals.

The analysis properly distinguished between a transient sensor glitch (C04 'None' value) and a persistent fault, adhering to the protocol requirement for direct fault evidence.

The identified thermal risk (bedroom dropping to 21.6°C while occupied) is a valid finding based on the provided logs, though severity depends on external context not present in the logs.

Evidence from chunks C04, C05, C19, and C23 provides a complete picture of morning activity, daytime stability, nighttime conditions, and late-night status, making the current dataset sufficient for a verdict.

温度异常上升但无合理热源（空调关闭/制冷模式，灶具关闭） 上升速度超过正常烹饪或日照导致的范围

火灾风险警报，建议住户检查该区域电器

The home is securely occupied with normal human activity patterns, consistent environmental conditions, and no evidence of intrusion or system faults.

Explanation: Occupancy data shows a clear transition from 'unoccupied' to 'occupied' states starting around 06:45, correlating perfectly with the activation of lights, AC, and cooking surfaces, indicating legitimate resident presence.

Explanation: Door lock events demonstrate secure behavior: manual unlocking at entrances followed immediately by automatic re-locking (e.g., C05 at 07:29, C14 at 16:04), with door contacts confirming closure, ruling out tailgating or forced entry.

Explanation: Environmental sensors report stable temperatures within a normal residential range (~23°C - 25°C) despite cooking activities, and temporary `None` readings during active cooking are expected sensor behaviors rather than failures or fire risks.

Sequence in C05 showing master_bedroom_occupancy=1, kitchen_cook_surface=on/off, front_door_lock=unlock->lock cycle within 1 minute.

Consistent occupancy reports for living_room and master_bedroom throughout evening chunks (C16-C19) matching user activity times.

Absence of any explicit Fault, Alarm, SmokeState, or intrusion-related events in the provided logs.

Continue standard monitoring; no immediate intervention required.

Verify physical operation of kitchen temperature sensor if `None` readings persist when not actively cooking, though current context suggests transient noise.

C14: Captures a period with high alarm counts (30) and mixed occupancy states, helping to isolate whether specific room sensors are malfunctioning independently of user presence.

The home is securely occupied by adults during the evening hours (18:00–21:20), with all main doors locked and monitored, and no signs of intrusion or environmental hazards.

DoorLock.LockState transitions show consistent manual unlocking followed by automatic locking (e.g., C05 at 07:29:24, C16 at 18:01:03).

OccupancySensing.Occupancy reports 'occupied' for Entrance and Living Room throughout the active evening periods, correlating with lights and AC being turned on/off.

Temperature readings remain within a stable range (~22.5°C to ~25.3°C) across all rooms, showing normal HVAC operation and cooking activity without overheating.

No alarm events, smoke states, or fault indicators are present in the provided log chunks.

Relies on the absence of negative evidence (no alarms logged); cannot definitively rule out silent sensor failures if logging is incomplete.

High frequency of entrance occupancy events could theoretically indicate unauthorized tailgating if not correlated with specific person detection, though current logs suggest legitimate user movement.

Consistent lock/unlock cycles matching human behavior patterns.

Stable temperature trends despite cooking activities.

Absence of any `SmokeState`, `Alarm`, or `Fault` event types in the logs.

Explicit alarm event logs mentioned in the Triage Output ('alarmish_count') are absent from the provided Focused Chunks; these would be critical to validate the hypothesis of system noise vs. false positives.

Data regarding pets or other non-human occupants to distinguish between pet interference and potential sensor malfunction causing frequent state flips.

Verify if the high frequency of `entrance_occupancy` transitions in C14/C16/C17 corresponds to distinct human entries or sensor noise (ghosting) by checking for associated door contact events or light activations immediately following each occupancy flip.

Confirm the absence of silent system faults: The logs show temperature sensors returning `None` during cooking (C05, C17), but no explicit `Fault` event is logged; ensure this isn't masking a hardware failure.

The Triage Output correctly identified 'alarmish_count' as a suspicious pattern in its summary, but the provided Focused Chunks do not actually contain an `alarmish_count` field. This confirms the investigator's finding that the specific evidence for 'system noise' mentioned in the triage hypothesis is missing from the selected chunks. However, the alternative hypothesis (normal occupied behavior with lock/unlock cycles matching human patterns) is strongly supported by the detailed event logs in C05 and C16.

The raw temperature values (e.g., 2275) are correctly interpreted as 22.75°C per Matter notes; there is no risk of false alarms due to unit misinterpretation.

The occupancy data shows consistent 'occupied' states for the living room and master bedroom during evening hours, correlating with lights/AC usage. The frequent entrance occupancy flips (approx. every 2-3 mins in C14/C16/C17) are plausible for a family moving between rooms or entering/exiting briefly, especially given the lack of intrusion attempts (door remains unlocked only during entry, then locks automatically).

Conclusion: The home appears securely occupied with normal environmental conditions. No critical security risks detected.

Normal household activity with routine entry/exit and sleeping patterns.

C00: House empty at 00:00, consistent with nighttime sleep cycle.

C05: Occupancy transitions to 'occupied' in Master Bedroom around 06:45, followed by lights turning off at 07:29, suggesting a resident waking up or moving through the house and settling in.

C14: Frequent door lock/unlock cycles (manual) between 15:54 and 16:50 while occupancy fluctuates, consistent with someone entering/exiting multiple times during the day (e.g., work arrival/departure, deliveries).

Temperature data shows stable readings (23-25°C) across all rooms, indicating HVAC systems are functioning normally without extreme drift.

The frequency of entrance occupancy events in C14 is high for a short window, though plausible for active households.

Verify alarm event source and count in late evening chunks (C16-C19) to distinguish between sensor noise, logic conflicts, or actual security breaches.

Correlate high-frequency entrance occupancy events in C14 with specific lock/unlock cycles to rule out pet interference or sensor malfunction vs. legitimate activity.

Check for missing temperature data points (e.g., kitchen sensor at 07:30:00) to ensure no environmental anomalies are masked by gaps.

The investigator correctly identified normal patterns in the provided chunks (C00, C05, C14). However, the Triage Output explicitly flags 'alarmish_count' peaking in C17 and potential false positives in C16-C19, which constitute critical safety risks not yet analyzed in the evidence.

The current evidence is insufficient because it lacks the specific log data from chunks C16 through C19 where the suspected anomaly occurs. Without seeing these logs, we cannot confirm if the alarms correlate with occupancy changes or represent system faults/noise.

Temperature values are correctly interpreted (e.g., 2275 = 22.75°C), so there is no false-alarm risk regarding literal temperature readings. The primary gap is the absence of the late-evening data required to validate the triage hypothesis.
