A cooking appliance was activated while the house was unoccupied, leading to a rapid temperature spike and triggering the kitchen smoke alarm.

Explanation: Occupancy sensors confirmed all rooms were empty from 00:00 until at least 03:15.

Explanation: At 02:58, the kitchen cook surface turned ON while no occupants were detected nearby.

Explanation: Kitchen temperature spiked dramatically from ~237°C (recorded as 2372 in raw log, likely scaled) to 2814 at 03:03, then dropped abruptly after the smoke alarm triggered at 03:13, indicating an automatic shutdown or fire suppression response.

Explanation: The sequence of events (cook start -> vacancy -> temp spike -> alarm) rules out external intrusion or false positives from steam, confirming an unattended hazard.

[2026-06-12T02:58:00] kitchen_cook_surface | OnOff = True

[2026-06-12T03:03:00] kitchen_temp_sensor | MeasuredValue = 2814

All occupancy logs show '0' between 02:58 and 03:13

Immediately dispatch emergency services if not already done due to the smoke alarm trigger.

Inspect the kitchen for burnt food, damaged appliances, or residual heat sources.

Reset the smoke detector and investigate why the system allowed a cook surface to activate without verifying local presence (check smart home automation logic).

SmokeCoAlarm 的 COState 变为 Warning 或 Critical

CO 报警是严重安全事件，不同于烟雾报警

紧急通知所有住户撤离，开窗通风，联系燃气公司

Active Carbon Monoxide alarm triggered in the kitchen while the house was unoccupied, indicating a potential gas leak or appliance malfunction requiring immediate attention.

Explanation: Occupancy sensors confirmed all rooms were empty (Occupancy=0) from 00:00 until 14:05, establishing an unattended cooking scenario or delayed leak detection.

Explanation: At 14:06:00, the kitchen smoke alarm explicitly logged 'COAlarm()' and 'COState = 1', confirming the presence of carbon monoxide rather than just smoke or heat.

Explanation: The temperature logs show rising temperatures in the kitchen prior to the alarm (from 2284 at 00:30 to 2375 at 03:30), suggesting a heating source may have been active or failing before occupants returned.

Explanation: While door lock events occurred later (07:35, 18:24), they followed normal patterns of entry/exit without forced re-locking anomalies, making them secondary to the critical safety hazard.

Multiple occupancy sensor readings showing Occupancy=0 for all rooms between 00:00 and 14:05

Immediately evacuate the premises if anyone is inside and call emergency services (911/local equivalent).

Do not re-enter the home until professional technicians verify the air quality and identify the leak source.

Check and replace batteries on the CO detector; test all connected appliances once cleared by professionals.

[2026-06-10T07:35:25] front_door_lock | DoorLock.LockState = 2

[2026-06-10T07:35:29] front_door_lock | DoorLock.LockState = 1

Check if the CO alarm event was resolved or acknowledged; verify if lights/alarms were manually silenced.

Correlate the exact timestamp of the CO alarm with kitchen appliance logs (dishwasher, cook_surface) to identify the source.

Review camera feeds or additional doorbell logs around 07:35, 18:24, and 21:46 to confirm if anyone entered or exited without authorization.

Verify the definition of 'Auto' lock operation to ensure it isn't a scheduled routine conflicting with the 'Manual' unlock.

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

A sustained kitchen temperature rise over several hours culminated in a smoke alarm activation while the home was unoccupied, indicating a potential fire hazard from unattended cooking or equipment failure.

Explanation: Kitchen temperature sensor readings show a continuous and significant increase from 22°C at 00:00 to 241°C by 04:25, well before the alarm triggered.

Explanation: The smoke alarm activated at 04:28:00, immediately following the peak temperature period, confirming a thermal event rather than a transient glitch.

Explanation: All occupancy sensors remained at 0 during the incident window (00:00–07:23), confirming the event occurred while the residence was empty, increasing the risk level due to lack of immediate human response.

Explanation: No door lock operations were recorded between the alarm event (04:28) and resident return (07:23), ruling out intrusion-related alarms.

1分钟内多次灯光开关 可能原因：智能家居系统被入侵/远程控制；设备自动化规则冲突；或电路问题 也可能是恐慌信号（住户通过反复开关灯试图引起注意）

通知住户检查是否有人误操作或系统异常

An intruder gained unauthorized access by opening the master bedroom window at 22:19:22 while the household was confirmed unoccupied, immediately triggering an automatic front door unlock sequence.

Explanation: Raw logs confirm occupancy sensors reported '0' for all rooms from 00:00:00 until 22:19:15 when the master bedroom sensor suddenly switched to '1', indicating a breach.

Explanation: At 22:19:22 (4 seconds after occupancy change), the master bedroom window motor command set the lift percentage to 10000 (fully open).

Explanation: Immediately following this, at 22:19:26, the front door lock triggered an 'Auto' unlock event and changed state to unlocked, suggesting a security system bypass or forced entry protocol rather than normal user behavior.

Explanation: The sequence of events (window open -> auto unlock) during a verified empty house period strongly indicates active intrusion rather than a false positive.

[2026-06-16T22:19:22] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Contact local law enforcement immediately to report a potential burglary in progress or recent break-in.

Do not enter the property; wait for police arrival to secure the scene.

Review camera footage specifically around 22:19:00 if external cameras are available to identify the suspect's entry method.

Check with neighbors to see if they witnessed any suspicious activity around 22:19.

[2026-06-16T16:18:00] front_door_lock | DoorLock.LockState = 2

Check contact_sensor logs for master_bedroom_window and entrance between 22:19:00 and 22:20:00 to confirm physical opening/closing events vs. just motorized position changes.

Verify if any motion triggers occurred in master_bedroom specifically at 22:19:26 (the occupancy log might be polling-based or delayed).

Review camera feeds (if available) or smart speaker audio logs around 22:19 to detect voice commands or human presence.

Cross-reference the 'Auto' unlock source at 22:19:26 with geofencing data to see if a trusted user was detected away from home.

No security threats detected; all observed events (occupancy changes, temperature drifts, and lock operations) are consistent with normal household activity patterns.

Explanation: The temperature readings (e.g., 2261-2409) represent scaled values (likely *10) for a normal range of ~22.6°C to 24.1°C, not overheating or sensor malfunction.

Explanation: Occupancy logs show legitimate human movement: residents were present in the living room/entrance between 02:30-03:00 and again at 07:37 and 18:06, refuting the hypothesis of an empty house during sleeping hours.

Explanation: The front door sequence at 07:37 shows a resident entering (contact closed), manually locking the door, and then the system auto-locking immediately after, which is standard secure behavior, not a break-in attempt.

## Focused Raw Log
[2026-06-25T00:00:00] kitchen_temp_sensor | T


CO 报警是严重安全事件，不同于烟雾报警

紧急通知所有住户撤离，开窗通风，联系燃气公司

A confirmed Carbon Monoxide alarm event occurred in the kitchen while residents were present, indicating a potential gas leak or malfunctioning appliance.

Explanation: The raw log explicitly records 'Event: COAlarm()' and 'COState = 1' from the kitchen_smoke_alarm at 20:46:00.

Explanation: Occupancy logs confirm that residents were present in the master bedroom and entrance area immediately prior to and during the alarm event (20:45-20:49), ruling out an empty-house false positive.

Explanation: While temperature readings show rising values consistent with evening heating/usage, they do not explain the specific CO detection trigger, confirming a safety hazard rather than a sensor drift error.

[2026-06-05T20:45:00] entrance_occupancy | OccupancySensing.Occupancy = 1

Immediately evacuate the household members to fresh air outside.

Do not re-enter the home until professional technicians have inspected the kitchen for gas leaks and verified the source of the CO emission.

Contact emergency services or a gas utility provider if symptoms of CO poisoning are experienced.

[2026-06-05T07:26:22] front_door_lock | DoorLock.LockState = 2

Check kitchen temperature and humidity logs between 20:45 and 20:47 to correlate with the CO alarm trigger.

Verify if the 'Auto' unlock at 22:34:26 was triggered by an internal schedule (e.g., garage opener simulation) or external signal.

Cross-reference master_bedroom_window contact sensor status at 22:34:19 to confirm if the window covering value corresponds to actual physical opening or is a sensor drift.

Review camera footage (if available) for the entrance time slot (22:30 - 22:40) to rule out break-ins.

跟 INS-02 的区别：这里不是暴力破解，只有1-2次尝试，且家中有其他房间的活动（说明有人在家）

Repeated lock operation failures during a period of detected occupancy suggest a mechanical or electronic fault rather than a successful intrusion attempt.

Explanation: Occupancy sensors triggered at 14:12:00 and 14:12:20 while the front door was being manipulated, indicating someone was present at the threshold.

Explanation: The system recorded two consecutive 'LockOperationError' events (Source=3) at 14:12:05 and 14:12:15, which deviates from normal user behavior patterns seen later in the day.

Explanation: Manual re-locking occurred at 16:35 and 17:53 without any subsequent error logs, suggesting the device recovered or was manually overridden after the initial failure sequence.

[2026-06-25T06:22:18] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 0

High activity count in kids_room (11 events) suggests presence, making a break-in less likely than internal adjustment, unless someone entered while the child was out.

Re-evaluating based on strict evidence: The jump from 0% to 100% is significant. If automated, why did the system log it as a salient event? It warrants verification.

Timestamps and source IPs/MAC addresses associated with the 'LockOperationError' events to determine if they originated from an external network attack or local device glitch.

Door contact sensor status immediately surrounding the 14:12 error timestamps to see if the door was physically opened/closed during the failure.

Automation rules or voice assistant logs around 20:41 to verify if the kids_room window opening was a scheduled task or manual trigger.

Motion sensor logs in the entrance hallway between 14:12 and 16:35 to detect any movement near the door after the lock errors.

The front door lock exhibits a critical malfunction where an auto-lock command is triggered immediately after a manual unlock, contradicting the sensor data which shows the door was physically closed (contact sensor flipped to True) before the lock engaged.

Explanation: At 07:50:25, the user manually unlocked and opened the door; at 07:50:27, the contact sensor confirmed the door was open (State=False), and at 07:50:31 it confirmed the door was closed (State=True).

Explanation: Despite the door being securely closed for only ~4 seconds, the system automatically locked the door at 07:50:32 (Source=Auto).

Explanation: This sequence contradicts normal behavior where the system waits for the 'door closed' signal or requires a manual lock action, suggesting a firmware glitch, sensor logic error, or unauthorized remote override rather than a standard user action.

[2026-06-09T07:50:31] front_door_contact | BooleanState.StateValue = True

Check the smart lock's firmware version and update if available.

Review the IP address and user agent of the 'Auto' lock command in the backend logs to rule out remote hacking.

Perform a physical inspection of the door strike plate and sensor alignment to ensure mechanical obstruction isn't causing false triggers.

Sequence: Manual Unlock -> Auto Lock on Front Door within 7 seconds (07:50:25 - 07:50:32)

Kids Room Curtains Closed (0%) while Occupancy is 0 at 06:47

Check if 'LockOperationType=0' (Auto Lock) at 07:50:32 was triggered by a proximity sensor failure, remote app command, or smartlock glitch rather than a physical turn.

Verify if any contact_sensor (kids_room_window or front_door_contact_sensor) triggered OPEN/CLOSE events around 06:47 or 07:50.

Cross-reference camera footage (if available) or motion sensor logs specifically for the kids_room between 06:47 and 08:00 to confirm no one entered.

Check the log source IP/User Agent for the 'Auto' lock command to rule out remote hacking attempts.

    "Sequence: Manual Unlock -> Auto


An intruder likely entered the unoccupied house overnight, manually unlocked the front door in the morning to exit, and subsequently left via a different route or timing that avoided immediate detection.

Explanation: Occupancy sensors confirmed zero presence in all rooms from midnight until 07:32 AM, establishing the house was empty during the critical night period.

Explanation: At 07:32:15, a manual unlock event occurred at the front door while occupancy remained zero inside, contradicting the 'routine departure' hypothesis which requires residents to be present.

Explanation: The sequence shows an occupant entering the entrance area (07:32:11) immediately before unlocking, suggesting the intruder was already on-site or just outside, rather than a resident waking up late.

Explanation: A second manual unlock occurred at 18:24 with occupants present, confirming normal operation only when people are inside, whereas the morning event was anomalous due to the lack of internal occupancy.

[2026-06-29T07:32:11] entrance_occupancy | OccupancySensing.Occupancy = 1

Secure the premises and review video footage for the entrance area between 00:00 and 08:00 to identify the intruder's entry point.

Check exterior sensors (balcony, hallway) for motion triggers during the overnight hours.

Inspect the physical state of the front door mechanism for signs of forced entry or tampering.

[2026-06-29T21:46:33] front_door_lock | DoorLock.LockState = 1

Possible intruder entry during the overnight period. An external actor may have entered when the house was empty, manipulated the lock manually, and left before the auto-relock triggered or was overridden.

Gap between last confirmed empty state (midnight) and first manual interaction (07:32)

Manually unlocked front door at 07:32 AM with zero occupancy recorded in all rooms for over 7 hours prior.

Automatic re-locking event occurred only 3 minutes after the manual unlock, suggesting the door might have been held open or forced ajar longer than expected, or the 'Auto' source triggered due to motion detection outside rather than just closing speed.

Check if any motion sensor triggered *outside* the perimeter (e.g., balcony, entrance hallway) between 00:00 and 07:32.

Verify the 'DoorOpenDuration' metric for the 07:32 event to see if the door remained open abnormally long.

Cross-reference weather data to rule out wind causing the door to swing and trigger the sensor falsely as a manual operation.

Check video footage (if available) for the entrance area between 00:00 and 08:00.

Multiple occupancy sensors are reporting a persistent state of zero occupancy while kitchen temperature sensors show rapid, unexplained drift into extreme values, indicating a critical sensor malfunction or communication failure rather than actual environmental conditions.

Explanation: Occupancy sensors across all rooms report '0' consistently from 00:00 to 07:30, which contradicts the typical human sleeping pattern (people do not vanish from bedrooms overnight).

Explanation: Kitchen temperature readings exhibit abnormal behavior: starting at 22.76°C and rapidly increasing to 41.8°C (2410) by 04:00, with no corresponding heating events or cooking activity logged.

Explanation: The simultaneous failure of independent sensor types (occupancy and thermal) suggests a systemic issue such as a power cycle, firmware glitch, or network partition affecting the entire sensor suite, rather than a physical intrusion or fire.

Explanation: No motion was detected in entrance areas during the night, ruling out an intruder moving through the house without triggering motion detectors.

Immediately verify the physical status of smart home devices (hubs, routers, and wall-mounted sensors) to check for power loss or disconnection.

Manually inspect room temperatures using a standalone thermometer to confirm if the high readings are real or digital artifacts.

A confirmed kitchen smoke alarm activation is supported by a critical temperature spike in the kitchen sensor just prior to the event.

Explanation: The kitchen smoke alarm triggered at 11:08 with SmokeState=1 and Event:SmokeAlarm().

Explanation: Kitchen temperature data shows a dangerous escalation from 2554°C (at 11:05) to levels consistent with severe combustion or sensor failure shortly before the alarm.

Explanation: While the absolute temperature values (e.g., 2554) are physically impossible for normal cooking and likely indicate a sensor malfunction or calibration drift, the correlation between the extreme reading and the simultaneous smoke alarm trigger constitutes a high-priority safety anomaly requiring immediate verification.

[2026-06-28T11:05:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2554

Immediately dispatch emergency services to verify the presence of fire.

The smoke alarm event is a confirmed false positive caused by sensor drift or calibration error, not an actual fire or combustion event.

Explanation: All occupancy sensors reported 0 (empty) at the time of the alarm (07:55), indicating no one was present to experience danger or cause cooking smoke.

Explanation: Temperature logs show a gradual increase from ~23°C overnight to ~25.3°C at the time of the alarm, which is consistent with normal ambient heating and does not indicate rapid combustion temperatures (>100°C).

Explanation: No HVAC shutdown, evacuation protocols, or subsequent fire suppression events were triggered in the logs, confirming the system treated the event as non-critical.

The sequence of window openings and occupancy spikes corresponds to routine resident activity (morning wake-up and evening return) rather than an intrusion.

Explanation: Occupancy logs show a brief spike in the kids' room at 01:30 followed by lights turning off, consistent with a child waking up or moving briefly before settling down, not an intruder.

Explanation: The morning event at 06:50 shows the light turning on immediately followed by the window covering opening (0%), which is standard behavior for a resident checking curtains or letting light in upon waking.

Explanation: The evening events (20:54 and 22:16) show windows opening sequentially just before the front door unlocks via 'Auto' source. This pattern indicates the homeowner returned home, opened windows for ventilation, and the system automatically unlocked the door as they approached/arrived, confirming authorized access.

Explanation: No contact sensors were breached, and the lock state transitions (Locked -> Unlocked) align perfectly with the timestamps of manual locks during departure and auto-unlocks upon return.

[2026-06-26T07:17:32] front_door_lock | DoorLock.LockState = 1

Contradiction Check: If kids window was opened at 20:54, why did the house become secure again? There is no record of the window closing or the front door being unlocked after 20:54 until the end of the log period which seems to wrap around or stop. Actually, looking at the timestamps: 06:50 (Closed), 20:54 (Open). Then master bedroom window opens at 22:16. This suggests windows are being opened sequentially in the evening while the house is supposedly empty (occupancy 0 at 00:00+).

No explicit 'window opened' alarm trigger listed in `suspicious_signals` other than the state change. Usually, smart homes have contact sensors for windows. The absence of a specific 'WindowContact.BreakIn' event makes this rely solely on window coverings data, which can be ambiguous.

Occupancy sensors show '0' (empty) starting at 00:00. If someone was inside opening windows at 20:54-22:16, they should have triggered occupancy sensors unless the intruder moved very stealthily or the sensors are blind spots.

Possible forced entry or tampering with window coverings simulating occupancy or hiding movement.

Sequence of events: Front door locked manually at 18:03. Later at 20:54, Kids room window covering moves to 100% (Open). Then at 22:16, Master bedroom window covers move to 100% (Open). Finally, front door unlocks automatically at 22:16:23 (likely geofencing return).

The pattern of opening multiple windows late at night (20:54, 22:16) when the house is registered as 'empty' (since 00:00) is highly irregular. A resident would typically not open all windows simultaneously right before returning home unless ventilating, but doing so sequentially across different floors/rooms without corresponding motion detection is suspicious.

If the homeowner arrived at 22:16 to unlock the door, why did they open the windows *before* unlocking the front door? One would expect to enter first, then open windows. Opening windows outside or through a window while the front door is still locked is less likely for a routine return.

The timing gap between the kids room window opening (20:54) and the master bedroom window opening (22:16) is over an hour. During this hour, the house was empty. Who opened the kids room window?

[2026-06-26T20:54:09] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

[2026-06-26T22:16:17] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Gap between window openings (20:54, 22:16) and subsequent front door unlock (22:16:23) where no occupancy was detected prior to these actions.

Check `kids_room_contact_sensor` (window sensor) state transitions between 20:54 and 22:16 to confirm if the window was physically breached or just covered adjusted.

Verify `entrance_occupancy` and `living_room_occupancy` logs specifically between 20:54 and 22:16 to see if any motion was missed or if the person moving the window was filtered out.

Cross-reference `front_door_lock` operation source code for the 22:16 event to confirm if it was truly 'Auto' (geofence) or 'Manual' (person holding phone).

Occupancy sensors are falsely reporting an empty house while temperature sensors indicate active heating/cooling cycles consistent with human presence.

Explanation: All occupancy sensors reported '0' (empty) continuously from 00:00 to 07:30, creating a false impression of an unoccupied home.

Explanation: Temperature sensors show a progressive and significant rise in living room temperature from 2282 (00:05) to 2513 (07:35), which is inconsistent with an unoccupied house where HVAC would likely be off or idle.

Explanation: The simultaneous failure of all room occupancy sensors to detect the activity implied by the rising temperatures indicates a systemic sensor malfunction or calibration drift rather than actual absence of residents.

living_room_occupancy consistently reports Occupancy = 0 throughout the night

living_room_temp_sensor shows continuous increase from 2282 to 2513 between 00:05 and 07:35

Immediately dispatch a technician to recalibrate or replace the faulty occupancy sensors.

Verify physical presence of residents via alternative means (e.g., doorbell camera, smart lock entry logs showing interior movement) until sensors are fixed.

Kitchen smoke alarm activation at 08:16 is confirmed by sensor state changes and coincides with occupancy in the master bedroom, indicating a potential fire hazard requiring immediate verification.

Explanation: The kitchen_smoke_alarm explicitly triggered (SmokeState=1, Event: SmokeAlarm) at 08:16:00, contradicting normal baseline conditions.

Explanation: Temperature readings in the kitchen showed a gradual rise (from ~2273 to ~2365 units over several hours), suggesting heat accumulation prior to the alarm, though no direct 'cook_surface' logs are visible in this excerpt.

Explanation: Occupancy data confirms residents were present in the house (Master Bedroom occupied at 08:16), making it an active household incident rather than a false positive caused by an empty house or environmental drift unrelated to cooking.

[2026-06-03T08:16:00] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

Immediately dispatch emergency services or verify via video/audio monitoring if available.

Evacuate occupants from the kitchen area immediately upon confirmation of smoke/fire.
