A significant fire hazard occurred in the kitchen while the residence was unoccupied for an extended period, indicated by a dangerous temperature rise and subsequent smoke alarm activation.

Explanation: Occupancy sensors confirm the house was empty from midnight until approximately 20:39 when the resident returned, with no human activity detected near the kitchen during this window.

Explanation: Kitchen temperature logs show a sustained and abnormal increase from ~22.7°C at midnight to ~43.8°C (2319K) by 2:35 AM, continuing to rise until the resident's return, indicating a heat source active without supervision.

Explanation: The smoke alarm triggered exactly at 22:06, correlating with the prolonged high-temperature event, confirming a combustion or overheating incident occurred while the home was vacant.

[2026-06-22T02:30:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2334

Immediately dispatch emergency services/fire department to investigate the kitchen fire origin.

Instruct the resident to inspect the kitchen for damaged appliances, wiring, or cooking equipment before restoring power/gas.

Review smart-home logs to identify if any automated heating devices or malfunctioning appliances contributed to the temperature spike.

Timestamps of motion sensor triggers immediately preceding the smoke alarm to see if a person entered the kitchen before the fire started (suggesting cooking accident vs. arson).

Door lock operation logs around 20:39 to confirm if the auto-unlock was authorized by the resident returning home or if it was tampered with.

Camera footage (if available) for the time window 22:00–22:10 to visually verify the nature of the smoke/fire.

Water leak detector status in the kitchen and bathroom to rule out water-related electrical hazards causing the fire.

A confirmed water leak occurred in the bathroom while the home was unoccupied and lights were off, indicating a potential pipe burst or appliance failure.

Explanation: Water leak sensor triggered at 22:12:00 with no subsequent reset or manual intervention log before detection.

Explanation: At the time of the leak (22:12), all room occupancy sensors reported zero, and the bathroom light was off (last seen on at 20:36).

Explanation: The system later detected occupancy in the living room at 22:13:00, confirming the resident returned after the incident began, consistent with an unnoticed event occurring during absence.

Dispatch immediate maintenance to inspect the bathroom for leaks or burst pipes.

Shut off the main water supply if flooding is suspected or cannot be located quickly.

Bathroom water leak detected at 22:12 while all rooms show zero occupancy.

Zero occupancy across all monitored rooms starting from 00:00 until at least 00:30, suggesting the resident left before midnight.

Door lock event logs to distinguish between 'Unlock' vs 'Lock' operations and verify if the door was actually breached or just cycled.

Window covering motor logs to check for torque errors or manual override flags during the 14:07 event.

Water leak detector signal strength and duration to determine if it's a continuous flood or a momentary trigger.

Historical occupancy patterns to confirm the expected departure time around 00:00.

Smartphone/Geofence logs to verify if the user actually left the home area before 00:00.

中等可信度警报，建议住户确认是否本人操作

A lock operation with an unknown source code and spoofed user index occurred while all occupancy sensors reported the house as empty for over 12 hours.

Explanation: All room occupancy sensors (living_room, bedroom, kitchen, bathroom, entrance) consistently reported '0' from 00:00 until 21:48, indicating total vacancy for more than 12 hours.

Explanation: The log shows a sudden spike in kitchen occupancy at 21:48:00 coinciding exactly with a front door lock operation using an anomalous 'OperationSource=8' and 'UserIndex=1', which contradicts the established resident routine of manual locking (Source=Manual).

Explanation: The simultaneous reporting of zero occupancy followed immediately by a single sensor detecting presence suggests either a sensor glitch masking entry or, more critically, that the entry was made before the sensors could register the occupant, fitting the profile of a forced entry or tailgating event.

[2026-06-22T00:00:00] ... entrance_occupancy | OccupancySensing.Occupancy = 0

[2026-06-22T21:48:00] kitchen_occupancy | OccupancySensing.Occupancy = 1

Immediately contact law enforcement to report a potential break-in.

Dispatch security personnel to verify physical damage to the front door and check for signs of forced entry.

Review network logs to trace if the 'OperationSource=8' originated from an external IP address or signal injection attempt.

High frequency occupancy reports showing '0' across all rooms during late night/early morning hours despite activity logs.

Lock operation at 21:48 with an unknown source code (8) and UserIndex=1, occurring while all room sensors report zero occupancy.

The timestamp 21:48 is inconsistent with the resident's established manual lock times (06:54, 08:40), suggesting an external actor or system glitch.

Complete lack of occupancy signals in living room, bedroom, kitchen, bathroom, and entrance between 00:00 and 00:30 suggests the house has been empty for over 12 hours prior to the suspicious lock event.

Raw binary data from the front_door_lock sensor at 21:48:00 to determine if the 'UserIndex=1' was derived from a valid key fob NFC read, a remote app command, or a signal injection/spoofing artifact.

Motion sensor raw voltage/current spikes or signal strength (RSSI) around 21:47 to check for human presence before the reported 'empty' state.

Network traffic logs to see if the lock command originated from an internal IP address (resident device) or an external IP range.

Check if 'UserIndex=1' corresponds to a known family member profile in the smart-home database, which would clarify if it's a trusted user accessing remotely.

Repetitive lock operation errors and an alarm indicate a mechanical failure or jamming at the front door, creating a potential security breach risk.

Explanation: Multiple LockOperationError events occurred in rapid succession (every 10-15 seconds) between 14:57:00 and 14:57:40.

Explanation: The sequence concluded with a DoorLockAlarm event, indicating the system detected a critical fault rather than a simple user error.

Explanation: Unlike typical user activity which shows successful manual/auto operations at different times, these errors are consistent with a device stuck in a failed state (e.g., mechanical jamming or internal circuitry failure).

Explanation: Although occupancy sensors later showed presence in the entrance area, the specific pattern of repeated failures followed by an alarm points to hardware malfunction as the primary anomaly.

[2026-06-15T14:57:00] ... Event: LockOperationError(OperationError=1, OperationSource=3)

[2026-06-15T14:57:50] ... Event: DoorLockAlarm(AlarmCode=3)

Dispatch a technician to physically inspect and test the front door lock mechanism immediately.

Check the lock's battery voltage to rule out power-related operational failures.

Review video footage from the entrance camera between 14:57 and 15:00 to verify if anyone was attempting to enter during the malfunction.

Sequence of 4 LockOperationErrors (Source=3) within 40 seconds ending in DoorLockAlarm on 2026-06-15T14:57

High frequency of events (1857 total) with 28 in entrance suggests potential徘徊 (loitering) or repeated access attempts around the time of the alarm

Timestamps of motion sensor triggers near the entrance during 14:56-15:00 to check for human presence outside.

Battery voltage level of the front_door_lock device to rule out power failure causing errors.

Detailed error code definition for 'OperationError=1' and 'Source=3' from device firmware documentation.

Video feed from entrance camera if available during the 14:57 timeframe.

The events are consistent with a resident returning home at night, turning on bedroom lights and curtains to check the view or prepare for sleep, followed by standard security locking.

Explanation: Occupancy logs confirm a human was physically present in the bedroom at 12:22 (when curtains opened) and at the entrance at 13:58 (when curtains closed), directly contradicting the 'empty home' anomaly hypothesis.

Explanation: The sequence of events shows a clear narrative: The resident entered at 08:23, left around 10:41, returned late at night (indicated by manual door unlock at 20:40:17 immediately preceding the auto-lock), and then manipulated the window covers shortly after arriving inside.

Explanation: No forced entry indicators exist; the window contact state did not trigger an alarm, motion sensors were active during the manipulation, and the timing aligns perfectly with a homeowner's routine behavior of securing the house before bed.

[2026-06-11T12:22:06] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-11T13:58:03] entrance_occupancy | OccupancySensing.Occupancy = 1

[2026-06-11T20:40:17] front_door_contact | BooleanState.StateValue = True (Followed immediately by manual lock)

Acknowledge the event as normal resident activity.

Review smart-home automation settings to ensure automatic lighting/curtain routines do not conflict with desired privacy modes if similar patterns occur again.

The sequence of the window changing states *before* the manual door lock at 20:40 is disjointed; the window changes occurred at 12:22 and 13:58, yet the door was only manually locked at 20:40. If the resident was present at 12:22 to open/close windows, why was the door not locked then? Or if they weren't present, who changed the windows?

Occupancy sensors report '0' (empty) for the entire day until the end of the log packet, contradicting the theory that a resident was home manipulating the window at noon.

Discrepancy between 'Empty Home' occupancy status and active device manipulation (window covering changes) during daytime.

Sudden re-opening of bedroom curtains (10000%) followed immediately by closing (0%), suggesting someone testing visibility or accessing the window.

Sequence: Window manipulated -> Door remains unlocked -> Door eventually locked (Auto then Manual) late evening.

Raw timestamp of the `bedroom_window` contact sensor state change to confirm if the window was physically opened/closed vs just curtains moving.

Motion sensor raw logs for the bedroom specifically between 12:00 and 14:00 to detect any human movement missed by the aggregate summary.

History of the `front_door_lock` unlock events to see if an unauthorized unlock preceded the final manual lock at 20:40.

Battery voltage history for the kitchen smoke alarm to rule out false low-battery alerts affecting other systems.

伪装开锁（被盗/复制凭证）

中等可信度警报，建议住户确认是否本人操作

An intruder entered the residence while occupants were absent during early morning hours, manipulated bedroom window coverings to observe the interior, and fled before the resident returned.

Explanation: Occupancy sensors confirm the house was completely empty (0%) from midnight until 06:51, with no motion detected in the kitchen or entrance where residents typically move upon waking.

Explanation: At 05:25, a light turned on followed by the full lowering of bedroom window blinds at 05:25:14; this specific sequence (light then blind down) is inconsistent with a resident trying to hide but consistent with an intruder attempting to darken the view for observation or testing the blind mechanism.

Explanation: The front door lock state changed from Locked to Unlocked between 06:51:10 (Manual operation) and 06:51:17 (Contact sensor False), indicating physical entry occurred while the house was still unoccupied. The subsequent auto-lock at 06:51:18 suggests the system reacted to the contact change after the person had already passed through.

Explanation: The cyclic manipulation of the window blinds later in the day (opening/closing) likely represents the same device being used to check if the system can be overridden or simply habit/curiosity, but the critical anomaly is the unauthorized entry during the known empty period.

[2026-06-09T06:51:10] front_door_lock | OperationSource=Manual -> [2026-06-09T06:51:17] front_door_contact | StateValue=False

Check surveillance footage around 05:25 AM and 06:51 AM immediately.

Change all access credentials (smart locks, Wi-Fi passwords) pending investigation.

Inspect bedroom window tracks and surrounding areas for signs of forced entry or tools.

Window covering fully lowered (0%) at 05:25:14, shortly before manual door lock engagement at 06:51:10.

Cyclic behavior: Bedroom window opened (0%), closed (10000%), opened again (0%) within a short span (12:22 to 14:10), repeated at 20:38.

Front door unlocked manually at 08:33:00 after being locked at 06:51.

Multiple state changes on the bedroom window sensor which may indicate physical manipulation rather than automated control.

Motion sensor logs for the bedroom between 05:00 and 07:00 to confirm if the resident was present when the window was opened/closed.

Audio logs from the bedroom or hallway around 05:25 and 14:10 to detect voices or sounds of struggle.

Detailed door lock log entries to verify if the 08:33:00 unlock was by the resident's phone/app or physically via key/fingerprint (UserIndex=1 vs Manual distinction).

Occupancy sensor history for the entrance and living room during the 05:00-09:00 window to rule out early rising.

烟雾报警器低电量时发生事件

警告住户烟雾报警器可能失灵，建议更换电池/设备

Evidence indicates an unauthorized entry into the home followed by manipulation of the bedroom window to simulate occupancy or cover tracks.

Explanation: The timeline shows the front door contact went from closed (True) to open (False) at 20:40:19-20:40:20, indicating someone entered while the door lock status was being recorded as unlocked/operating via 'Auto'.

Explanation: Within minutes of this entry event (at 20:40:32), the bedroom window was opened (Position=10000), which is inconsistent with a resident leaving for the night but consistent with an intruder creating noise/distraction or hiding inside.

Explanation: Crucially, no occupancy sensor in the kitchen or living room triggered between 20:40:19 and 20:40:32, suggesting the person who entered did not traverse these main areas; they likely entered directly to the bedroom or hid immediately after entering.

[2026-06-02T20:40:19] front_door_contact | BooleanState.StateValue = True

Immediately call local law enforcement to report a potential break-in.

Do not enter the residence until police have cleared the property.

Check if any smart cameras or speakers have audio/video feeds covering the time window to identify the intruder's appearance.

The tight temporal correlation between the final door unlock (20:40:20) and the final window opening (20:40:32) is unusual if these are independent actions by a healthy elderly person without assistance; typically, one would close windows before leaving or secure them differently. The rapid sequence might indicate forced access followed by immediate cover-up or an accomplice inside.

High number of 'salient' vs 'focus' events (60 vs 97) implies significant noise or unexpected triggering patterns not typical of simple routines.

[2026-06-02T20:40:20] front_door_lock | DoorLock.LockState = 1

Check motion sensor logs for entrance, living room, and kitchen immediately after 20:40:20 to see if someone entered and exited rapidly or remained hidden.

Verify if the 'Auto' lock/unlock sources correspond to scheduled automation rules or actual user interaction via app/voice.

Check battery status history for the smoke alarm to rule out false battery alerts causing confusion in the timeline.

Cross-reference smart speaker or camera feeds (if available) around 20:40 to visually confirm who performed the window operation.

烟雾报警器低电量时发生事件

警告住户烟雾报警器可能失灵，建议更换电池/设备

The home was occupied by an unauthorized individual between midnight and early morning, evidenced by the bedroom light turning on at 05:31 AM while all occupancy sensors remained empty.

Explanation: All room occupancy sensors reported '0' (empty) from 00:00 until 08:32, yet a specific event occurred at 05:31:06 where the bedroom light turned ON.

Explanation: This is immediately followed at 05:31:13 by the window covering lifting to 0% (fully open/down depending on logic, but clearly active), indicating human interaction inside an empty house.

Explanation: No legitimate resident could have triggered these events as they were absent; the subsequent door lock auto-unlock at 20:41 suggests the intruder may be exiting or the system is reacting to a breach scenario.

[2026-06-10T05:31:06] bedroom_light | OnOff.OnOff = True

[2026-06-10T00:00:00] *all* rooms occupancy | OccupancySensing.Occupancy = 0

Contact local law enforcement immediately to report a potential break-in.

Review security camera footage for the front door and bedroom exterior around 05:30 AM.

Change all access codes and smart locks immediately.

[2026-06-10T00:00:00] *all* rooms occupancy = 0 (suggests absence during overnight hours)

[2026-06-10T05:31:13] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 0 (window opened at 5:31 AM while house appears empty)

[2026-06-10T20:41:27] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 (window closed immediately after door unlock at 20:41)

Simultaneous total house vacancy (all rooms 0) from 00:00 to 00:30 followed by specific window activity in the bedroom at 05:31 while no occupants are detected inside.

Door unlocked at 20:41 (evening) immediately followed by window manipulation (closed then open sequence logic check needed, but timing aligns with potential intrusion egress or ingress).

Window covering state change to '0' (fully down/closed?) at 05:31 AM with zero occupancy anywhere in the home.

Raw motion sensor data for the bedroom between 05:00 and 06:00 to confirm if any micro-movement occurred despite the aggregated '0' report.

Timestamp correlation between the front door lock state change at 20:41 and the subsequent window event at 20:41:27 to determine causality.

History of the 'WindowCovering' sensor calibration or default values to ensure '10000' and '0' represent distinct physical states (e.g., fully open vs fully closed) and not a glitch.

Audio logs or smart speaker transcripts around 05:31 to rule out voice commands triggering the window coverings remotely.

The events are consistent with a resident managing the home environment (opening windows for ventilation) after arriving and setting up the morning routine.

Explanation: Occupancy logs show clear human presence in the bedroom starting at 06:54, contradicting the hypothesis of an unoccupied house during the window events.

Explanation: The sequence shows the resident turning on the bedroom light at 05:34, followed by opening the window at 12:27 (likely for ventilation while present), which is a normal behavior pattern.

Explanation: The 'Auto' unlock event at 20:48 coincides exactly with the resident entering the bedroom again and interacting with lights/windows, indicating automated security routines triggered by the occupant's return, not a breach.

[2026-06-09T06:54:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-09T12:27:07] bedroom_occupancy | OccupancySensing.Occupancy = 1

Sudden drop to zero occupancy across all sensors at exactly 00:00:00 could indicate a sensor calibration reset or communication loss rather than actual absence.

The specific times of window operations (daylight hours) and the high activity count elsewhere suggest the resident is likely managing the environment themselves.

[2026-06-09T12:27:11] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 0

[2026-06-09T14:08:02] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

[2026-06-09T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

Motion sensor raw data for bedroom between 12:00 and 15:00 to confirm if anyone entered/exited.

Control command logs for bedroom_window to determine if the window state changes were triggered by an automation rule, a voice command, or manual actuation.

Network connectivity logs to verify if occupancy sensors went offline or reset at 00:00:00.

Timestamp precision check on front_door_lock events to see if the 'Auto' unlock at 20:48:19 corresponds to a scheduled smart-home routine or an emergency override.

The sequence of events represents a resident waking up early, leaving for the day (06:55), returning mid-morning (08:21) to retrieve an item or check the property, and then resuming normal afternoon activities.

Explanation: Occupancy sensors were empty overnight but showed presence in the bathroom at 05:40 and kitchen at 06:55, confirming the resident was home before the first manual door unlock.

Explanation: At 06:55, the front door was manually unlocked, opened (contact False), and immediately re-locked by auto-lock (0.7s later), consistent with a resident leaving quickly.

Explanation: At 08:21, the resident returned: entrance occupancy detected at 08:20, followed by manual unlock, door opening, and closing. The subsequent window toggling and light usage align with typical daytime routine, not intrusion behavior.

Explanation: There is no evidence of forced entry, prolonged unauthorized stay, or conflicting sensor data indicating multiple occupants.

[2026-06-29T05:40:00] bathroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-29T06:55:06] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) ... [06:55:13] ... Auto

[2026-06-29T08:20:09] entrance_occupancy | OccupancySensing.Occupancy = 1

No immediate action required; event log confirms normal household activity.

Sequence: Manual Door Unlock (08:21) -> Long Gap -> Bedroom Window Opened (14:09). If the occupant left at 08:21, why was the window opened inside? If they stayed, why the late morning unlock?

Occupancy Sensors all show '0' (empty) starting from 00:00:00 through the morning hours (00:30, 06:55 events), yet the door is manipulated manually at 08:21. This implies either the sensor failed, the person is out of range, or someone else was present but not detected (intruder).

Rapid toggling of bedroom window state between 12:39, 14:09, and 20:36 suggests active manipulation rather than natural drifting.

Check camera feeds or smart speaker logs around 08:21 and 14:09 to confirm if the resident was present or absent.

Verify if the 'Manual' lock operation at 08:21 corresponds to the resident using a key/app vs. a forced entry event (some locks report 'manual' for both).

Cross-reference thermostat or light usage in the bedroom between 08:00 and 14:00 to determine if the room was occupied.

Check if the occupancy sensor reset at 00:00:00 was a scheduled maintenance or a genuine detection of emptiness.

触发安全警报，临时禁用 Keypad 输入，通知住户

Multiple failed lock operations followed by a successful manual unlock and entry occurred while the home was unoccupied, indicating a likely break-in attempt.

Explanation: The house occupancy sensors registered '0' (unoccupied) for all rooms from midnight until 06:27, establishing that no one was present during the incident window.

Explanation: At 06:25, there were four rapid consecutive 'LockOperationError' events with source code 3, immediately followed by a 'DoorLockAlarm(AlarmCode=3)' at 06:25:50, which is consistent with forced manipulation or repeated tampering attempts.

Explanation: Despite the alarm, the door was successfully unlocked via 'Manual' operation at 07:05:10, and the contact sensor confirmed the door opened ('False') before closing again, proving the barrier was breached.

Explanation: Occupancy was detected in the kitchen at 06:27:04 (approx. 12 minutes after the breach), confirming someone entered the property.

[2026-06-07T07:05:12] front_door_contact | BooleanState.StateValue = False

Contact local law enforcement to file a report regarding the forced entry.

Check security camera footage specifically between 06:25 and 07:05 to identify the intruder.

Inspect the physical door hardware for signs of tampering (e.g., drilled locks, broken strike plates).

Consider resetting or reprogramming the lock system if 'OperationSource=3' indicates a compromised key fob or smart device.

A significant temperature rise in the kitchen preceded a smoke alarm activation while the residence was empty, indicating an unattended cooking incident or fire hazard.

Explanation: Kitchen temperature rose steadily from ~22°C at midnight to ~240°C (likely scaled value indicating extreme heat) by 04:30, far exceeding normal ambient levels.

Explanation: At 06:37, the kitchen occupancy sensor confirmed the room was empty (Occupancy=0), yet the smoke alarm triggered simultaneously with a resident being detected elsewhere in the house.

Explanation: The resident left the premises shortly after the alarm (locking door at 07:06) without any log evidence of resetting or acknowledging the alarm, suggesting a potential failure to address the active hazard.

[2026-06-28T04:30:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2412

[2026-06-28T06:37:00] kitchen_occupancy | OccupancySensing.Occupancy = 0

Immediately inspect the kitchen for signs of fire, smoke damage, or burnt appliances.

Reset the smoke alarm and test its functionality to ensure it is not stuck in a fault state.

Review camera footage if available to verify the exact time of departure versus alarm activation.

The door contact sensor is reporting contradictory states (False then True) while the lock mechanism successfully cycles through locking and unlocking operations without physical obstruction, indicating a hardware or firmware glitch rather than an intrusion attempt.

Explanation: Analysis of the raw log at 07:08:02 shows a 'Manual' lock command followed by an 'Auto' unlock at 07:08:06, which is consistent with user behavior (e.g., checking the lock) or system automation, not necessarily forced entry.

Explanation: The critical evidence lies in the `front_door_contact` sensor readings at 07:08:04 (StateValue=False) and 07:08:05 (StateValue=True). A rapid toggle like this during a successful lock/unlock cycle suggests the sensor is bouncing, stuck, or misreading the magnetic reed switch, rather than someone physically opening and closing the door.

Explanation: No occupancy sensors were triggered at the entrance during this 4-second window, and subsequent logs show normal activity patterns (lights on/off, curtains moving) consistent with residents being present and active inside the home.

[2026-06-22T07:08:04] front_door_contact | BooleanState.StateValue = False

[2026-06-22T07:08:05] front_door_contact | BooleanState.StateValue = True

Inspect and clean the door contact sensor magnet and reed switch for debris or interference.

Check smart lock firmware for known bugs related to contact sensor feedback loops.

Replace the door contact sensor if cleaning does not resolve the erratic state toggling.

Timestamps and duration of the front door contact sensor triggering between 07:08:02 and 07:08:06 to confirm if the door was physically opened.

GPS location or geofence data associated with the 'Manual' lock source to verify if it originated from inside the home or remotely.

Motion sensor logs for the entrance and kitchen immediately surrounding 07:08:00 to detect human presence during the lock/unlock cycle.

System error logs for the smart lock to rule out firmware bugs causing false Auto-unlock triggers.

SmokeCoAlarm 的 COState 变为 Warning 或 Critical

紧急通知所有住户撤离，开窗通风，联系燃气公司

The smoke alarm was triggered by a sensor malfunction (drift) rather than a real fire, as indicated by the absence of temperature spikes and no occupancy during the event.

Explanation: Occupancy sensors consistently reported '0' (empty house) from midnight until morning, ruling out residents cooking or intruders present in the kitchen at 02:45.

Explanation: Kitchen temperature readings remained stable (~23°C/71°F) throughout the night and showed no spike at the time of the alarm, which contradicts the physics of a burning object triggering a CO/smoke alarm.

Explanation: The alarm logic incorrectly mapped a stable temperature reading to a hazard state ('COState=1', 'Event: COAlarm()'), indicating a software bug or sensor calibration drift rather than a physical threat.

[2026-06-03T02:45:00] kitchen_occupancy | OccupancySensing.Occupancy = 0

[2026-06-03T02:45:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2349

Reset the kitchen smoke detector immediately.

Schedule maintenance to calibrate or replace the kitchen temperature/safety sensor.

Review alarm threshold settings for potential software bugs causing false positives on static temperatures.

[2026-06-03T20:52:20] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Smoke alarm triggered (COState=1) at 02:45 when all occupancy sensors reported 0 (empty house).

Manual lock operation on the front door at 06:54 immediately following the smoke event time, potentially indicating an intruder securing the scene or leaving, though it could also be the resident returning early.

Repeated manual lock operations combined with automatic unlocks suggest complex interaction patterns that deviate from standard 'wake-up -> leave' routines.

Kitchen cook_surface status logs between 02:00 and 03:00 to confirm if stove was active during the smoke alarm trigger.

Front door contact_sensor logs around 02:45 and 06:54 to determine if the door was opened before the smoke alarm or if someone entered/exited manually.

Video feed or motion sensor timestamps in the kitchen and hallway specifically around 02:45 to rule out false positives caused by pets or shadows.

Bedroom window contact_sensor logs to correlate with the curtain position changes and verify if windows were open during the night.

烟雾报警器低电量时发生事件

烟雾报警器处于低电量状态
厨房有高温活动但烟雾传感器未触发
两个信号组合：低电量 + 温度上升但烟雾传感器无反应 → 设备可能失灵
这是复合推理场景，需要关联两个独立信号

警告住户烟雾报警器可能失灵，建议更换电池/设备

The front door was manually unlocked while the contact sensor indicated it was closed, followed immediately by a state change to open and then an auto-relock, strongly suggesting an unauthorized individual entered after the resident opened the door.

Explanation: At 07:08:06, the lock received a manual unlock command (Type=1) while the door contact sensor reported 'False' (closed/locked).

Explanation: Exactly 2 seconds later at 07:08:08, the contact sensor switched to 'True' (open), indicating the door was physically opened despite the system reporting it was still locked/closed.

Explanation: The door remained open for ~9 seconds before an automatic re-lock occurred at 07:08:17, matching the pattern of a tailgater entering and exiting before the auto-latch engages.

Explanation: A similar suspicious sequence occurred at 08:33:00, reinforcing the pattern of potential repeated incidents or a compromised security routine.

[2026-06-01T07:08:08] front_door_contact | BooleanState.StateValue = False -> True (Open)

Contact the resident immediately to verify if they recognize anyone entering their home during the windows around 07:08 and 08:33.

Instruct the resident to check surveillance footage if available to visually confirm the presence of an intruder.

Review the device firmware settings to ensure the 'Auto-Re-lock' feature is enabled and functioning correctly to minimize exposure time on future attempts.
