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 sequence of events represents a standard resident interaction with the smart lock (initial error followed by successful operation) within an occupied home, consistent with normal daily routine and window adjustment patterns.

Explanation: All occupancy sensors across the entire house were active or showed presence shortly before and after the incident, contradicting any 'empty house' intrusion scenario.

Explanation: The specific error event was immediately resolved by a successful lock operation from the same source, indicating a transient technical glitch rather than a sustained forced entry attempt.

Explanation: The subsequent log entries show the resident closing the front door contact and adjusting bedroom windows, confirming the user is inside and managing their own environment normally.

[2026-06-26T20:41:11] bedroom_light | OnOff.OnOff = True

Monitor the smart lock for recurring error codes to determine if maintenance is needed.

No immediate security intervention required as the resident is confirmed present and secured.

Timestamped video feeds from entrance camera to see if someone was present during the error event.

Identity mapping of 'UserIndex=1' against known authorized residents.

Audio logs from the smart lock to determine if forceful interaction occurred before the error.

Motion sensor logs in the entrance hallway specifically around 19:25 to correlate presence with the lock event.

FG-03-FP: 烟雾报警器自检触发CO检测

The sequence of events at 20:51 represents a standard evening routine where the resident entered the home (auto-unlock), turned on lights, opened blinds for ventilation or light, and then closed them to sleep.

Explanation: Door lock operation at 20:51:10 is explicitly tagged 'Auto' with state change to unlocked (1) immediately after contact closure, consistent with the system's programmed return-home unlock logic seen at 07:06.

Explanation: Bedroom light turned ON at 20:51:18, indicating presence and intent to use the room, which contradicts an intruder scenario who would likely avoid lighting.

Explanation: Window position changes (close at 20:51:10, open at 20:51:25) occurred within seconds of light activation and before lights were turned off (20:51:28), suggesting manual adjustment by an occupant for comfort/ventilation rather than tampering.

Explanation: No security alarms, smoke detectors, or leak sensors were triggered during this window.

[2026-06-30T20:51:18] bedroom_light | OnOff.OnOff = True

Continue monitoring normal household patterns.

Check if the door lock operation at 20:51:10 was an external unlock (tamper) vs internal manual/unlock sequence.

Verify the source of the window motor command at 20:51:10 (manual app control vs. automatic routine vs. unknown trigger).

Cross-reference motion sensor logs between 20:50 and 21:00 to see if anyone entered the room while the window was being manipulated.

Confirm if the resident typically opens/closes bedroom windows manually at this specific time or if it is an automated schedule.

有人在卫生间正常使用中触发，且短时间内恢复为 false

The system triggered a false burglary alert due to an occupancy sensor malfunction (kitchen reported presence at 06:52) combined with a door state inversion caused by a sensor fault, rather than an actual intrusion.

Explanation: Occupancy sensors consistently reported '0' from midnight until 06:51:58, yet the kitchen sensor falsely spiked to '1' at 06:52:02 exactly before the manual lock event, indicating a hardware glitch or environmental interference affecting that specific sensor node.

Explanation: The sequence shows a manual lock attempt followed immediately by an auto-unlock and a door contact state flip (False -> True), which is characteristic of a lock mechanism reacting to a faulty proximity signal or a mechanical jam rather than human tailgating.

Explanation: Subsequent logs show normal resident behavior: lights turning on in the bedroom at 05:40, window adjustments at 12:34, and standard evening departure procedures at 20:35, confirming no sustained unauthorized entry occurred.

Explanation: The absence of motion in other rooms during the incident and the return to normal occupancy patterns shortly after (bathroom sensor clearing at 06:53) supports a localized sensor failure over a coordinated break-in.

[2026-06-18T06:52:12] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto) AND DoorLock.LockState = 1

Replace or recalibrate the kitchen occupancy sensor immediately.

Verify mechanical integrity of the front door lock actuator and check for debris in the strike plate.

Review alarm log settings to suppress alerts when single-point sensor faults occur without corroborating video or multi-sensor confirmation.

Door Lock State transition from 2 (Locked) to 1 (Unlocked) at 06:52:12 immediately following a manual lock attempt.

Complete absence of occupancy data in all rooms between midnight and early morning despite active door events.

Raw camera footage or doorbell log for the period 06:51:00 - 06:53:00 to see if anyone approached the door.

Specific definition of LockOperationType values (1 vs 0) and LockState values (1 vs 2) to confirm if the 'Auto' unlock was a genuine command or a fault code.

Motion detection sensitivity settings and blind spot analysis for the entrance hallway and bedroom at 06:52.

Timestamp synchronization between the door lock module and the occupancy sensor modules.

Evidence strongly indicates an unauthorized entry where a suspect opened the front door and entered the bedroom without triggering occupancy sensors, likely by turning off their motion detection or bypassing the sensor.

Explanation: The house was confirmed empty (all rooms occupancy=0) from midnight until 20:41.

Explanation: At 20:41:14, the front door lock state changed to UNLOCKED (State=1) via an 'Auto' operation, which is inconsistent with normal resident behavior for a locked home at night.

Explanation: Immediately following the unlock at 20:41:14, the bedroom window curtains were opened at 20:41:32, but no corresponding 'Occupancy=1' event was recorded in the bedroom log until 12:31 the next day.

Explanation: The sequence of unlocking the door followed immediately by opening the bedroom window suggests forced entry or tailgating by an intruder who avoided detection by the motion sensor.

[2026-06-21T20:41:32] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 (Curtains opened)

No 'bedroom_occupancy' event between 20:41:14 and the next morning's 12:31:09

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

Do not enter the property; wait for authorities.

Check security camera footage if available to identify the intruder's appearance or vehicle.

Change all access codes and locks upon safe return.

Check raw motion sensor logs for 'bedroom_occupancy' specifically between 20:40:00 and 20:45:00 to confirm if anyone entered the room.

Verify the source IP or device ID associated with the 'Manual' lock operation at 20:41:14 to distinguish between app control and physical key/remote use.

Review camera footage (if available) or doorbell log entries around 20:41:00 to see who approached the entrance door.

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 simultaneous events at 20:36 constitute a standard automated security routine (auto-lock upon departure) triggered by the front door contact closing, not an intrusion.

Explanation: At 20:36:19, the front door contact sensor registered 'True' (closed), indicating the occupant had just left the house or closed the door from inside.

Explanation: Immediately following this (20:36:20), the system executed an 'Auto' lock operation and set the lock state to '1' (locked), which is consistent with a scheduled departure protocol.

Explanation: The bedroom window opening event at 20:36:25 occurred only 5 seconds after the auto-lock, coinciding with the activation of the bedroom light. This sequence strongly suggests a user manually opened the window to ventilate immediately after leaving the room/house, rather than an unauthorized entry attempt.

Explanation: There is no evidence of forced entry (e.g., repeated toggling, missing motion sensors in the vicinity during an active breach, or temperature spikes indicative of a struggle). The high activity counts in other rooms (Kitchen/Living Room) noted in Stage-1 are likely artifacts of the summary log aggregation or unrelated background processes, as individual occupancy logs show 0 for those specific timestamps.

[2026-06-10T20:36:23] bedroom_light | OnOff.OnOff = True

Continue monitoring; no immediate action required.

Verify that the 'Activity Count' metrics in the dashboard do not correlate directly with individual sensor triggers to avoid future confusion.

[2026-06-10T20:36:25] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Check camera feeds or smart doorbell footage around 20:36 to see if anyone approached the bedroom window.

Verify the source of the Front Door Lock operation at 20:36:20; determine if it was a manual unlock by an authorized user or an automated system failure.

Cross-reference the 'room_activity' counts for 20:30-21:00. The log shows 21 activities in Living Room and 22 in Kitchen. Confirm if this corresponds to legitimate household members cooking/cleaning or suspicious loitering.

Inspect the `suspicious_signals` list for any missing temperature spikes near the bedroom window that might indicate forced entry.

Manual front door unlocks occurred while the home was completely unoccupied, followed immediately by auto-re-locking and contact closure, indicating a likely unauthorized entry attempt or tailgating.

Explanation: Occupancy sensors confirmed 100% vacancy across all zones (including entrance) during the two manual unlock events at 07:01 and 08:26.

Explanation: The sequence shows a manual unlock, door opening (contact false), rapid auto-re-lock, and door closing (contact true), which is inconsistent with normal resident behavior when away.

Explanation: No occupancy spike preceded these events, ruling out the resident entering and exiting naturally.

Immediately review camera footage for the 30-minute window prior to 07:01:04 to identify approaching individuals.

Check local police logs or notify authorities if no authorized user can account for the access.

Auto-locking followed immediately by Manual unlocking suggests potential tailgating or forced re-entry if the occupant was not present.

Check camera feeds (if available) or motion sensor raw data for the 30-minute window prior to 07:01:04 to see if a person approached the door.

Verify if the 'Manual' operation source corresponds to a specific user ID or just a generic override command.

Check if there were any subsequent motion detections in the entrance hallway after the 08:26:00 unlock event.

Automated front door unlocking followed by bedroom window opening while all occupancy sensors report zero presence indicates a likely unauthorized entry simulation or actual intrusion.

Explanation: Occupancy sensors reported '0' across all rooms from 00:00:00 until 20:37:16, confirming the home was unoccupied during the evening events.

Explanation: At 20:37:11, the front door lock triggered an 'Auto' unlock operation (OperationSource=0), which is inconsistent with normal human behavior for an empty house and suggests automated exploitation.

Explanation: Immediately following the unlock at 20:37:19, the bedroom window coverings were lifted to 100% (fully open), creating an access point consistent with H1 hypothesis.

Explanation: This sequence contrasts sharply with the morning routine (07:03) where manual locking/unlocking coincided with immediate occupancy detection, proving the system's sensors work when people are present.

Evidence strongly indicates an unauthorized entry between midnight and 6:50 AM, where an intruder entered while the house was unoccupied, locked themselves out or manipulated the lock, and left before the resident returned.

Explanation: All occupancy sensors reported '0' (empty) from 00:00 until 06:50:06, yet the temperature rose significantly, suggesting a lack of active heating/cooling adjustment by a human or potential tampering.

Explanation: At 06:50:09, the front door contact briefly went to 'False' (open), followed immediately by a manual lock operation and a subsequent auto-lock event, indicating someone accessed the interior and departed.

Explanation: The bedroom light turned on at 05:30 AM while the house was still officially 'empty' according to sensors, followed shortly by the curtain closing and then the suspicious door interaction sequence.

INS-05-FP: 住户换了新手机/手表解锁

The event involving 'UserIndex=8' is a benign automated action triggered by the presence of a resident (Occupancy=1), consistent with standard smart-home automation rather than an intrusion.

Explanation: At 10:55, when UserIndex=8 triggered the lock operation, the system simultaneously recorded bedroom_occupancy as 1, confirming a legitimate resident was present and interacting with the environment.

Explanation: The rapid window covering changes observed later in the day (e.g., at 14:00) correlate directly with occupancy events in the bedroom and living room, indicating they are manual or auto-adjustments made by residents responding to light conditions.

Explanation: All other lock operations show clear patterns of human presence (entrance_occupancy=1) immediately preceding state changes, ruling out silent remote access or physical tampering without detection.

[2026-06-22T10:55:00] ... OccupancySensing.Occupancy = 1

Rapid toggling of bedroom window coverings (0 -> 100%) between 14:00 and 20:41

Door lock state changing to Unlocked (1) immediately after the suspicious User 8 event at 10:55

Raw binary payload of the front_door_lock event at 10:55 to verify if 'UserIndex=8' corresponds to a registered device/app or is an unrecognized MAC address/IP.

Motion sensor logs for the entrance and kitchen around 10:55 to confirm if a person was physically present when the door was manipulated.

Camera feeds (if available) or audio logs for the bedroom corridor between 14:00 and 20:41 to correlate curtain movements with human presence.

Check if 'UserIndex=8' has been whitelisted in the smart-home configuration.

The sequence represents a standard resident arrival and departure routine with a minor initial lock access error and subsequent normal automated behaviors.

Explanation: All occupancy sensors reported '0' (unoccupied) from 00:00 until 06:12, confirming the home was empty during the incident window.

Explanation: The error at 06:12:00 followed immediately by a successful unlock using UserIndex=1 (a known resident profile) at 06:12:20 indicates a failed remote attempt by the owner that succeeded upon their physical arrival, rather than an unauthorized breach.

Explanation: Subsequent logs show consistent patterns of door locking/unlocking, window cover operations aligned with daylight hours, and occupancy spikes only when residents are present, ruling out stealthy intrusion or sensor malfunction.

[2026-06-30T06:12:20] front_door_lock | Event: LockOperation... OperationSource=3, UserIndex=1

Occupancy sensors remained at 0 until 07:03, well after the morning activities concluded.

No immediate action required; system is operating normally.

Optional: Review if User Index 1's device ID matches the expected smartwatch/phone to confirm identity mapping.

Rapid fluctuation between locked and unlocked states.

Bedroom window position changes (0% to 100%) occurring without corresponding high-motion sensor events inside the bedroom, which might indicate forced entry from outside or sensor disconnect.

Timestamps of window movement align with daylight hours (05:23, 12:30, 20:37), making random night-time tampering less likely unless pre-planned.

Morning and evening lock operations at 07:00 and 20:37 are highly consistent with waking up and retiring routines for an elderly person.

All room occupancy sensors reporting 0 during the 06:12 - 08:27 timeframe

Identity mapping for 'OperationSource=3' (Is it a known smartwatch, phone app, or unknown device ID?)

Raw motion sensor data specifically for the entrance hallway and bedroom immediately before and after the 06:12 event to rule out stealthy entry.

Time-stamped logs for the bedroom window cover actuator to verify if the change was commanded by an app or mechanical force.

Check if the 'LockOperationError' was resolved by the same source that succeeded 20 seconds later, or if a different source intervened.

开窗前住户先在同一房间活动并开灯，是主动行为

The sequence of manual lock followed immediately by an auto-unlock indicates a smart-lock system malfunction rather than a successful intrusion or forced entry.

Explanation: Occupancy sensors confirm the house was empty from 00:00 to 06:58, supporting the premise that no resident was present to manually unlock the door after locking it.

Explanation: The event log shows the front door contact sensor triggered (Door open) exactly one minute before the 'Auto' unlock command, suggesting the door opened due to a mechanical failure (e.g., latch disengaging) or a scheduled automation error, not human interaction.

Explanation: Crucially, the occupancy sensor in the kitchen registered a presence ('1') at 06:58:07, only 2 minutes after the door cycle, indicating the resident entered shortly after the anomaly resolved, consistent with returning home to find a glitching lock rather than being caught inside by an intruder.

[2026-06-10T06:58:07] Kitchen Occupancy = 1 (Resident returns)

Check physical status of the front door lock cylinder and strike plate for misalignment.

Reset the smart lock firmware or perform a factory reset if the issue persists on the next cycle.

Monitor the door contact sensor behavior during the next day to ensure no recurring false triggers.

Event sequence: Manual Lock (06:56:02) immediately followed by Auto Unlock (06:56:13). This suggests either a system malfunction triggered by tampering, or an intruder testing the lock mechanism.

Door lock state transitioned to Unlocked (1) shortly after being manually locked.

Check if there are any motion sensor triggers in the entrance hallway between 06:55 and 06:57.

Verify the type of 'Auto' unlock command: Was it triggered by a smart home schedule (unlikely at this hour), a voice command, or a technical error code?

Review the duration of the door being unlocked; did it remain open long enough for entry?

Check window contact sensors in the bedroom to see if they were triggered around the same time as the door events.

The observed events are consistent with a resident leaving the house manually and returning via an automated routine (e.g., geofencing or timer), not an intrusion.

Explanation: Occupancy sensors registered presence at 06:50:02 (bedroom) and 06:51:08 (kitchen) immediately preceding and following the manual lock event, proving the resident was inside during the 'Manual' operation.

Explanation: The sequence shows the door contact opening (False) then closing (True) within seconds of the manual lock, followed immediately by an 'Auto' unlock event, which is characteristic of a resident exiting via physical handle while the system logs a subsequent automated state correction or scheduled open.

Explanation: Subsequent window and lighting activities (opening windows, turning on lights) occurred only when occupancy sensors detected the resident present (12:27 and 20:39), confirming these actions were performed by the occupant, not an intruder.

[2026-06-20T06:50:02] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-20T06:51:08] kitchen_occupancy | OccupancySensing.Occupancy = 1

[2026-06-20T12:27:13] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Monitor for continued normal activity patterns; no immediate intervention required.

Verify if the 'Manual' lock source in the log corresponds to the physical handle mechanism as expected for exit events.

Window covering changing from closed (0) to open (10000) and back suggests physical interaction, not just a timer, especially if paired with door manipulation.

Manual lock operation at 06:50:09 and 08:40:00 coinciding with zero occupancy across all rooms.

Bedroom window position fluctuating (Closed -> Open -> Closed -> Open) between 06:50 and 20:39 while no one is detected inside.

Discrepancy between 'Manual' lock source and 'Auto' source within minutes of each other without corresponding human movement events.

Check the raw motion sensor logs for the entrance hallway and living room immediately preceding and following the 06:50:09 manual lock event to rule out false negatives in occupancy detection.

Verify the timestamp accuracy of the bedroom window motor logs against the main system clock to ensure no synchronization drift causing apparent anomalies.

Inspect the audit log for any failed unlock attempts or repeated key code entries before the successful manual lock operation.

Cross-reference the smart plug or HVAC logs to see if any power draw spikes correspond to the window motor activity, confirming mechanical action vs. sensor glitch.

An intruder gained entry through the front door (verified by contact sensor) and immediately attempted to access the bedroom via the window while the system was in an automated arming sequence.

Explanation: Occupancy sensors confirmed human presence in the bedroom starting at 22:54:06, contradicting the long period of unoccupied status reported from midnight onwards.

Explanation: The intrusion timeline shows a direct correlation: the front door contact triggered (opening/closing event) at 22:54:15 was immediately followed by the window opening command at 22:54:11 (note: log order in raw excerpt seems reversed or simultaneous with door event, but context implies intruder accessed door then went to window), and critically, the door lock auto-command occurred at 22:54:16 AFTER the window opened, suggesting the system reacted to the breach rather than preventing it initially.

Explanation: The rapid sequence of events (Door Contact -> Window Open -> Door Lock Auto) within seconds indicates a forced entry scenario where an intruder entered, moved to the bedroom, and the smart home system subsequently executed its 'Auto' lock routine, likely interpreting the door state change as a trigger.

Immediately notify law enforcement of the potential break-in.

Dispatch security personnel to verify the scene if not already done.

Review video footage from any exterior cameras around the time of the front door contact event.

Check the source IP/MAC address of the 'front_door_lock' Auto lock command to determine if it originated from a known user device or an unknown external source.

Verify if there are any motion sensor triggers in the hallway, living room, or bedroom between 22:54:00 and 22:55:00 that correlate with the door/window events.

Review the state history of the kitchen and living room windows around 22:54 to see if other entry points were compromised simultaneously.

Check if the 'bedroom_window' actuator received a direct manual override command versus an automated script execution log.

Evidence indicates a potential intruder entered the residence via the front door and exited through the bedroom window during a period of confirmed vacancy.

Explanation: Occupancy sensors confirm all rooms were empty between 21:59:32 (window opening) and the subsequent timestamp checks, making resident activity highly improbable.

Explanation: The sequence shows the front door being manually unlocked at 07:28:22 followed immediately by auto-locking, suggesting an entry event, while the bedroom window was opened fully at 21:59:32 with the front door locked, indicating a specific egress pattern.

Explanation: The lack of any occupancy triggers in the bedroom or living room around the time of the window operation strongly contradicts a normal resident routine.

[2026-06-30T00:00:00] ... [2026-06-30T05:30:00] OccupancySensing.Occupancy = 0 for all monitored rooms

Immediately review camera footage for the front entrance (07:28) and bedroom window area (21:59) to identify the perpetrator.

Secure the perimeter and consider changing smart home credentials or lock codes pending investigation.

Check camera footage (if available) for the entrance hallway and bedroom window area around 21:59 to see who or what interacted with the window.

Verify if any motion sensor triggers occurred in the bedroom or living room within 5 minutes prior to the window opening event at 21:59:32.

Cross-reference the 'Auto' source on the 07:28 lock event; verify if it corresponds to a smart-home schedule or a panic button trigger.

An intruder entered the house through an open bedroom window while the occupant was inside, exited via the front door just before it auto-locked, and left the house empty.

Explanation: Occupancy sensors confirm a person was present in the bedroom at 22:50:15 immediately prior to the event.

Explanation: The bedroom window was opened (100%) at 22:50:17 while occupancy was detected, indicating forced entry or egress rather than a routine action.

Explanation: The front door contact triggered (open) at 22:50:27, exactly one minute after the window was opened and shortly before the door locked automatically, confirming an exit path was used by someone who was not the resident (who turned off the light at 22:50:34).

Explanation: The house was empty (occupancy=0) for the entire preceding night shift (00:00 to 08:33), ruling out normal arrival/departure routines.

An unauthorized individual entered the home through the front door while a resident was inside, exited immediately after locking the door from the inside, and left via the bedroom window.

Explanation: Occupancy sensors confirm a resident was present in the bedroom at 23:06:08.

Explanation: The front door contact sensor triggered (StateValue = True) at 23:06:19, indicating the door was opened from the outside while the house was occupied.

Explanation: Immediately following the entry, the front door lock engaged automatically at 23:06:20, which is consistent with an intruder entering and quickly securing the perimeter before fleeing.

Explanation: Crucially, no 'UnlockOperation' event was recorded prior to the lock engagement, ruling out a resident opening their own door from the inside.
