有人在卫生间正常使用中触发，且短时间内恢复为 false

The system indicates a sensor malfunction where occupancy sensors consistently reported 'empty' rooms while temperature data showed significant heating activity, indicating the sensors are stuck or misconfigured rather than detecting an intrusion.

Explanation: Temperature logs show continuous heating (rising from ~22°C to ~24°C) throughout the night, which contradicts the claim that no one was home and would typically lower heat settings.

Explanation: Occupancy sensors remained at 0 for all rooms between 00:00 and 07:25 despite the active heating cycle, suggesting the sensors failed to detect presence or were calibrated incorrectly.

Explanation: The door lock sequence at 07:25 is consistent with normal resident behavior (manual lock upon entry followed by immediate auto-lock), and there is no evidence of forced re-entry or multiple rapid toggling attempts.

[2026-06-02T01:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2322

Calibrate or replace the motion/occupancy sensors in the living room and entrance.

Review thermostat schedules to ensure energy efficiency if residents do not return until late evening.

[2026-06-02T22:04:35] front_door_lock | DoorLock.LockState = 1

The discrepancy between 'room_activity' logs showing significant events in Entrance/Living Room versus explicit 'Occupancy=0' status from sensors in those same areas.

Raw motion sensor voltage/IR breakage timestamps to distinguish between 'no person detected' and 'sensor malfunction'.

Door contact sensor state transitions specifically around 07:25:08 to verify if the door was opened before being manually locked.

Network packet captures for the front_door_lock device between 07:25:00 and 07:25:20 to check for multiple rapid lock/unlock commands or remote access attempts.

Historical occupancy baseline for this time of day to confirm if 00:00-01:00 is typically empty or if recent patterns have shifted.

The sequence of events represents normal smart-lock behavior (manual lock followed by an automatic unlock cycle) occurring during periods of high household occupancy with no signs of intrusion or forced entry.

Explanation: Occupancy sensors confirm residents were present in the entrance and living areas immediately before and after the suspicious timestamps, making an unauthorized break-in highly improbable.

Explanation: The log shows a clear pattern of 'Manual Lock' (Type=1) immediately followed by 'Auto Unlock' (Type=0) within seconds, which is consistent with a convenience feature (e.g., locking while holding a package, then auto-unlocking upon sensing presence) rather than tampering.

Explanation: Contact sensor logs show stable states (False indicating closed/locked, True indicating opened/unlocked) without rapid jittering or repeated open/close cycles that would indicate jiggling or forced entry attempts.

[2026-06-24T07:32:32] front_door_contact | BooleanState.StateValue = True (Door Opened/Auto-Unlocked)

Subsequent activity at 22:11 shows identical manual-to-auto transition logic confirming it is a recurring system behavior, not an anomaly.

Review smart lock settings to understand the specific trigger for the 'Auto Unlock' feature after manual locking.

No immediate security action required; continue monitoring standard occupancy patterns.

[2026-06-24T18:09:00] front_door_lock | DoorLock.LockState = 2

Subsequent logs at 18:09 and 22:11 follow similar patterns (Manual Lock -> State Change) but occur later in the evening when residents are typically present.

High room activity counts suggest occupants are actively using the house, making a silent break-in highly improbable.

Check the device firmware version and configuration for the front_door_lock to verify if 'Auto-unlock after manual lock' or similar convenience features are enabled.

Review motion sensor data for the entrance hallway between 07:32:24 and 07:32:33 to see if a human passed through immediately after the manual lock event.

Correlate the 'UserIndex=5' event at 12:05:00 with known family member profiles to ensure it matches a legitimate user.

Inspect raw contact_sensor logs for the front_door to confirm there were no rapid open/close cycles indicative of jiggling or tampering.

Occupancy sensors are reporting false 'empty' states while kitchen temperature readings indicate active heating cycles consistent with human presence.

Explanation: All motion sensors report zero occupancy from 00:00 to 05:35, which contradicts the expected behavior if residents were awake or had recently vacated (doors/appliances would likely show state changes).

Explanation: Kitchen temperature rose steadily from 2269 (likely ~22.7°C) at 00:00 to 2459 (likely ~24.6°C) by 05:30, a pattern typical of HVAC systems running in an occupied home rather than a vacant one where temperatures would stabilize or drop.

Explanation: The simultaneous failure of all motion sensors to detect activity despite environmental data suggesting occupancy points to a systematic sensor drift or calibration failure rather than normal absence.

[2026-06-27T00:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2269

[2026-06-27T05:35:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2459

Continuous 'Occupancy = 0' across all rooms for over 5 hours

Manually verify physical occupancy and check for residents in the home immediately.

Inspect and recalibrate/reboot all occupancy sensors to restore accurate monitoring.

The sequence of events indicates a resident returning home late at night (22:18), manually locking the door immediately after entry, and opening the window, rather than an intrusion attempt.

Explanation: Occupancy sensors show the master bedroom was empty all night until 22:18:06, confirming no one was inside prior to the event.

Explanation: At 22:18:17, the front door lock state changed from locked (2) to unlocked/ajar (1) via 'Auto' source, which contradicts the hypothesis of a break-in followed by locking; instead, it aligns with the resident entering and triggering auto-lock or manual unlock logic upon return.

Explanation: The front door contact sensor shows the door opened (False) at 22:18:16 and closed (True) shortly after, consistent with someone entering through the front door.

Explanation: The window opening (100%) and subsequent turning off of the light at 22:18:23 are consistent with a resident settling in for the evening after arriving home.

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 rapid lock/unlock sequence is a legitimate result of an occupancy sensor detecting a resident exiting the entrance area shortly after manual locking, followed by an automated routine reversing the state to match the 'away' mode.

Explanation: Occupancy sensors confirm zero presence in all rooms from midnight until 07:12:08, indicating residents have been away for hours.

Explanation: At 07:12:08, the entrance occupancy sensor detected a person (likely a resident returning briefly or checking the door), triggering the manual lock at 07:12:12 and closing the contact sensor.

Explanation: The immediate re-opening of the contact sensor (07:12:16) coincides with the detection of movement near the entrance, which likely triggered an automation rule to unlock the door (Auto source at 07:12:17) to allow passage, consistent with the later scheduled auto-unlock at 22:08.

Explanation: No forced entry signals exist; the door contact sensor was never bypassed, and no other security alerts were generated.

[2026-06-18T07:12:08] entrance_occupancy | OccupancySensing.Occupancy = 1

[2026-06-18T07:12:14] front_door_contact | BooleanState.StateValue = False

[2026-06-18T07:12:16] front_door_contact | BooleanState.StateValue = True

Review smart-home automation rules to determine if the 'Manual Lock -> Auto Unlock' sequence is the intended behavior for morning routines.

Verify battery levels on the front door lock and entrance motion sensor if this pattern recurs unexpectedly outside of known schedules.

[2026-06-18T18:13:00] front_door_lock | DoorLock.LockState = 2

[2026-06-18T22:08:40] front_door_lock | DoorLock.LockState = 1

The presence of a valid 'Auto' unlock event later at 22:08 suggests the lock system is functioning and responding to schedules.

All other security sensors (contact sensors on windows/doors) do not report breach events in the suspicious_signals list, implying no forced entry was detected elsewhere.

Check the raw motion data for the entrance hallway between 07:12:12 and 07:12:17 to see if a person was present during the rapid lock/unlock cycle.

Verify the battery level and firmware version of the front door lock to rule out communication glitches causing phantom auto-unlocks.

Cross-reference the 'Auto' unlock source ID at 22:08:40 with the resident's known schedule to confirm it is a legitimate automated routine.

The system logs indicate a routine evening departure followed by normal automated night-time behavior with no signs of intrusion or sensor malfunction.

Explanation: UserIndex=5 explicitly locked the front door at 18:32, establishing a secure exit.

Explanation: All occupancy sensors across the house reported '0' consistently from midnight onwards, confirming total absence.

Explanation: The event at 23:04 shows the door contact closing (StateValue=True) and an auto-lock operation, which is consistent with standard smart-home routines after the user leaves.

FG-03-FP: 烟雾报警器自检触发CO检测

The smart lock erroneously unlocked itself while the door was already open and no human interaction was recorded, indicating a sensor or logic failure rather than an intrusion attempt.

Explanation: Occupancy sensors confirmed no humans were present in the entrance or living areas at 22:23.

Explanation: The front door contact sensor reported 'True' (door closed) just seconds before the auto-unlock event, contradicting the premise of someone exiting to unlock it from the inside.

Explanation: No manual operation source was detected; the system automatically commanded an unlock (LockOperationType=0) while the door state was effectively closed, which is inconsistent with standard security routines.

FG-04-FP: 低电量报警但传感器仍正常工作

虽然电池低但传感器仍然能正常检测烟雾（SmokeState变1又恢复0），说明设备没失灵

Evidence confirms the front door was physically opened and held open for approximately 8 seconds between a manual lock attempt and an automatic unlock, indicating a forced entry or tailgating event.

Explanation: At 07:37:25, the user manually locked the door (LockState=2), but immediately at 07:37:27, the contact sensor triggered False (door opening).

Explanation: The door remained open (sensor=False) until 07:37:33, totaling ~8 seconds of physical breach.

Explanation: This delay caused the system to trigger an 'Auto Unlock' at 07:37:34 to prevent locking while open, contradicting the initial manual security action.

Explanation: Subsequent logs show occupancy in the entrance at 08:52 and 09:02, suggesting someone entered during or after this event.

[2026-06-18T07:37:33] front_door_contact | BooleanState.StateValue = True

Review video footage from the front door camera between 07:37:25 and 07:37:40 to identify the intruder or cause of the door movement.

Check if any items were taken from the entrance area or kitchen (where smoke alarm later triggered).

[2026-06-18T18:11:00] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual)

[2026-06-18T22:39:24] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Door state logs show LockState=2 (Locked) at 07:37:25, but the log order suggests an immediate transition to State=1 (Unlocked) shortly after, potentially indicating the door was held open or manipulated before being locked again.

Time-series inconsistency: Manual Lock (07:37:25) immediately followed by Auto Unlock (07:37:34). This pattern often indicates a door held ajar, forced entry attempt where the lock disengaged under pressure, or an intrusion bypass.

High frequency of entrance events (27 total) compared to other rooms, concentrated around the suspicious 07:37 timestamp.

Raw GPIO or magnetic contact sensor logs for the front_door_contact_sensor specifically between 07:37:25 and 07:37:40 to verify if the door actually opened and closed or remained open.

Video footage from any existing camera covering the entrance hallway or exterior door area around 07:37 AM.

Timestamp precision alignment between the door lock motor driver logs and the contact sensor trigger logs to rule out clock skew causing false 'Auto' readings.

The events represent normal resident behavior: a brief absence detected by sensors was followed immediately by the resident's return (occupancy=1), manual locking, and subsequent auto-unlock upon re-entry.

Explanation: Occupancy sensors registered zero presence in all rooms from midnight until 07:17:05, confirming the house was empty during that window.

Explanation: At 07:17:05, the entrance occupancy sensor triggered (value=1) exactly one minute before the manual lock event, indicating the resident had just entered the threshold.

Explanation: The door contact sensor shows a clean open/close cycle (False at 07:17:15, True at 07:17:21) consistent with the resident entering to lock up and then leaving briefly or adjusting items, not a forced breach.

Explanation: The 'Auto' unlock source at 07:17:22 corresponds to standard smart-lock proximity unlocking after the manual lock cycle completed, typical of resident interaction, not a system reset or intrusion signal.

[2026-06-08T07:17:21] front_door_contact | BooleanState.StateValue = True

No immediate action required; logs indicate normal household activity.

Ensure motion sensor sensitivity settings are calibrated if false 'empty house' alerts occur frequently near entry points.

[2026-06-08T21:47:35] front_door_lock | DoorLock.LockState = 1

Manual lock operation at 07:17:13 occurring simultaneously with zero occupancy across all monitored rooms (Living Room, Master Bedroom, Entrance, etc.).

Sequence of 'Manual Lock' followed immediately by 'Auto Unlock' suggests the door was opened manually (potentially by an intruder forcing it open and then unlocking it, or a resident who was not detected by motion sensors).

Door contact sensor state transitions immediately surrounding 07:17:13 and 18:10:00 to determine if the door was physically breached before being locked.

Motion sensor raw data logs for the Living Room, Hallway (Entrance), and Front Door area between 07:00 and 08:00 to confirm lack of human presence.

Camera snapshots or video feeds associated with the front door event log to visually verify if a person was present or if the door was forced open.

Check if the 'Auto' unlock source corresponds to the smart lock's auto-unlock feature triggered by proximity, which would imply the resident was nearby but not triggering the motion sensor, OR if it indicates a system reset after a breach.

The occupancy sensors are reporting '0' (empty) while temperature sensors simultaneously record a rapid and continuous rise from ~22°C to ~25°C, indicating active heating or human presence that the motion detectors failed to register.

Explanation: Occupancy sensors for all rooms remained at '0' throughout the night (00:00-07:25), suggesting no one was detected moving in the house.

Explanation: Simultaneously, kitchen and living room temperature sensors recorded a steady increase from 22.76°C to 25.10°C, which is physically inconsistent with an empty, unheated home during these hours.

Explanation: This discrepancy indicates that either a person was present but invisible to the motion sensors (e.g., lying still, obscured by camera angle) or the occupancy sensors are malfunctioning/failing to detect movement despite thermal activity.

The system logs confirm a standard residential evening routine with authorized lock operations and no signs of intrusion or sensor malfunction.

Explanation: All occupancy sensors report '0' (empty) consistently from midnight through the morning hours, indicating no one was inside the house after the initial exit sequence.

Explanation: Two distinct lock operations at 12:59 and 13:04 occurred shortly after the house emptied, consistent with residents locking up before sleep rather than unauthorized entry attempts.

Explanation: Temperature readings show a gradual rise typical of an unoccupied home in summer, with no sudden spikes indicative of fire, gas leaks, or stuck appliances.

只有1-2次错误（非连续多次），最终成功解锁且 UserIndex 是合法用户

The smart lock failed to engage automatically after the door was closed and manually opened by an authorized user (UserIndex=1), leaving the front door unlocked for a significant duration despite occupancy returning inside.

Explanation: At 07:39:20, a successful unlock event occurred with 'OperationSource=3' and 'UserIndex=1'. Given that UserIndex=1 is known to be a resident (who locked up at 16:17 and returned at 07:35), this indicates an authorized entry.

Explanation: Immediately following the manual open at 07:39:22, the log shows the door contact opening. However, unlike previous events where 'OperationSource=Auto' triggered locking upon closing (e.g., at 07:28 or 22:22), no auto-lock event follows the 07:39 sequence in the logs provided.

Explanation: Occupancy sensors confirm a resident was present inside the master bedroom at 07:35 and again at 16:15/17:45, indicating the system expects the door to secure itself when residents are inside.

Explanation: The failure of the automatic locking mechanism (LockState remaining open) after an authorized entry constitutes a critical security lapse, as it leaves the home vulnerable until the next manual intervention or power cycle.

Review motion sensor logs for the entrance and living room between 22:22:27 and 22:22:18 (note the window closing/locking sequence anomaly) to see if anyone entered.

Confirm if OperationSource=3 represents a physical key, app control, or specific user profile.

The event sequence represents a normal evening exit where the user manually locked and closed the front door after leaving the house.

Explanation: Occupancy logs confirm the user was present in the entrance area at 16:06 and left around 16:23.

Explanation: At 17:51, the manual lock operation (LockOperationType=1) was immediately followed by a contact sensor reading of False (door opening) and then True (door closing), indicating the user physically exited through the door they just locked.

Explanation: Unlike an intrusion attempt, there is no subsequent motion detection or occupancy spike in the hallway after the door was locked at 17:51; instead, the system remained empty until the night-time return at 22:28.

Explanation: The state transition from Locked (2) to Unlocked/Open (implied by contact False) back to Locked (1) via Auto at 22:28 confirms the standard 'Goodnight' routine rather than a breach.

No action required; log entry confirms normal user behavior.

Timestamped contact sensor logs for the front door between 17:45 and 18:00 to confirm if the door was physically opened/closed manually without an authorized unlock command.

Motion sensor logs in the entrance hallway immediately following the 17:51 lock event to detect if someone entered after the user presumably left.

User authentication logs to verify if UserIndex 5 corresponds to an authorized family member or if the 'Manual' operation at 17:51 lacked proper biometric/keypad verification.

只有1-2次错误（非连续多次），最终成功解锁且 UserIndex 是合法用户

A single failed front door unlock attempt followed immediately by a successful manual unlock from an authorized user indicates a transient system glitch rather than a security breach.

Explanation: The failure event at 07:01:00 (OperationError=1) was immediately resolved by a successful operation at 07:01:20 from the same source (UserIndex=1), which matches the morning departure pattern confirmed by occupancy logs.

Explanation: No unauthorized access attempts, forced entry motions, or subsequent suspicious lock/unlock cycles occurred after the initial error.

Explanation: The sequence aligns perfectly with normal household activity: residents preparing to leave, experiencing a momentary smart-lock hiccup, and successfully exiting manually.

[2026-06-02T07:49:23] front_door_lock | DoorLock.LockState = 2 (Door opened shortly after)

Review firmware version for the front door lock; consider a scheduled update if this error code recurs frequently.

Monitor battery levels of the front door lock unit to rule out low voltage causing intermittent failures.

An unknown user (UserIndex=5) unlocked the front door while all room occupancy sensors reported zero activity, indicating an intrusion into an empty home.

Explanation: At 21:20:00, a lock unlock event occurred with 'UserIndex=5', which is not a known resident index and contradicts the pattern of manual/auto locks by family members.

Explanation: Crucially, the raw log shows that at 21:20:05, immediately following the unlock, the entrance_occupancy sensor changed from 0 to 1, confirming physical entry.

Explanation: Prior to this event, between midnight and 20:48, all room occupancy sensors consistently reported 0, establishing that the household was unoccupied.

Video feed logs from the entrance area around 21:20:00 to visually identify the individual associated with UserIndex=5.

Network connection logs for the door lock device at 21:20:00 to verify if the unlock command originated from a local physical switch vs. a remote smart-home app login from an external IP address.

第二人通过合法凭证解锁（不同UserIndex），且有合理时间间隔

The events indicate an authorized user performing routine lock operations while the home is empty, with no evidence of intrusion or unauthorized access.

Explanation: All occupancy sensors (Living Room, Kitchen, Bedrooms, Entrance) consistently report 'Occupancy = 0' throughout the entire timeline, including immediately before and after the door lock events.

Explanation: The door lock events at 11:53 and 11:58 explicitly show 'LockOperationType=1', which corresponds to a locking action, not an unlocking or entry attempt.

Explanation: The presence of multiple UserIndices (1 and 2) with the same OperationSource suggests a standard smart-lock feature (e.g., auto-locking on departure or app-based locking from different registered devices) rather than physical tailgating or breach.

Timestamped log entries confirm OccupancySensing.Occupancy = 0 for all rooms at 00:00 through 12:00.

Front door lock logs record 'LockOperation(LockOperationType=1)' at 11:53 and 11:58, confirming the door was locked, not opened.

No action required; system behavior is consistent with normal automated security routines.

Continue monitoring standard sensor data.

[2026-06-06T11:58:00] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=3, UserIndex=2)

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

Concurrent state of 'Empty House' (all occupancy=0) vs 'Active Door Lock Operations' with multiple user indices.

Timestamp gap analysis: The last clear occupancy zero at 01:00 precedes the door lock events at 11:53+; need to verify if occupancy was still 0 during the lock events.

Exact timestamps of the Front Door Lock events vs. the most recent Occupancy=0 reading for Living Room and Entrance before the lock events occurred.

Definition of OperationSource=2 and OperationSource=3 (Device ID mapping to specific phones/cards).

Directionality of the LockOperation (Lock vs Unlock) - is Type=1 consistently Locking?

Motion sensor raw data around the time of the lock events to detect if anyone was physically present at the entrance before the lock status changed.
