WD-03-FP: 住户外出但开了自动浇花系统

漏水传感器触发后在短时间内（3分钟）恢复为false，而非持续触发超过10分钟

The event log indicates normal household activities including morning departure and evening return, with no evidence of forced entry or unauthorized access.

Explanation: The log shows a consistent pattern of resident behavior: blinds closing in the morning (06:47), manual locking upon exit (07:10), and manual unlocking/entering followed by auto-locking at night (22:45).

Explanation: At 17:43, the front door was manually locked while occupancy was detected inside the master bedroom, which is consistent with a family member returning home and securing the door after entering.

Explanation: The window covering change in the kids' room at 20:45 occurred without any corresponding contact sensor trigger indicating the window was physically opened or occupied by an intruder, suggesting it was likely a routine adjustment or automated schedule.

Explanation: No motion sensors were triggered immediately after the 17:43 lock event to suggest someone remained outside or entered unnoticed.

Continue monitoring standard daily patterns.

Review camera footage if available to visually confirm the identity of the person who operated the door at 17:43 for user reassurance.

Occupancy sensors in kids_room showed 0 occupancy at midnight, but no immediate occupancy spike reported around 20:45 in the salient list; however, lack of explicit denial makes this weakly supported.

Check the exact timestamp difference between the 17:43 Manual Lock event and the previous 16:28 Manual Unlock event to determine dwell time outside.

Verify if there was any forced entry override signal on the door lock motor before the manual operation.

Cross-reference the 20:45 kids_room_window blind opening with the contact_sensor log for the kids_room_window to see if the window was physically open or just the covering moved.

Review camera footage (if available) or doorbell logs for the period surrounding 17:43 to visually confirm who operated the door.

WD-02-FP: 洗碗机正常排水溅到传感器

漏水传感器在1分钟内恢复为false，且洗碗机正常完成运行周期，说明只是排水溅水

The event sequence represents authorized occupants ventilating a room and triggering an automated door unlock, consistent with normal evening routines.

Explanation: Occupancy sensors confirm the presence of people in the master bedroom (22:37:15) and entrance (20:49:03), ruling out unauthorized entry from outside.

Explanation: The window opening at 22:37:22 was followed by a contact sensor reading 'True' (closed/engaged) just 5 seconds later at 22:37:27, indicating the occupant remained inside and did not exit through the window.

Explanation: The front door unlocked automatically ('Auto') immediately after the window opened, which is a standard smart-home behavior when windows are detected open or as part of a scheduled routine, rather than a manual intrusion attempt.

Explanation: No new occupancy was detected entering the house after the door unlocked at 22:37:28; the only occupant movement recorded afterwards was lights turning off.

Explanation: The subsequent light-off event at 22:37:36 confirms the occupant settled back into the room, completing a logical cycle of ventilation and settling down.

22:37:15 master_bedroom_occupancy = 1 (Person present)

22:37:27 front_door_contact = True (Door physically closed before unlock command)

22:37:28 LockOperationSource = Auto (Not manual/unauthorized)

No action required. Continue monitoring.

Optional: Verify if the user intended to leave the house around this time based on context not visible in logs.

[2026-06-17T07:18:39] front_door_lock | DoorLock.LockState = 1

The log indicates the previous unlock at 22:37:28 resulted in LockState=1. If the user was inside opening the bedroom window to ventilate, they would logically have been present to unlock the door themselves, making this less suspicious unless the timing implies someone else did it.

No motion sensor triggers listed between 22:37:22 and 22:37:28 to confirm presence or absence during the exact moment of the door state change.

Timestamp 22:37:22: kids_room_window OR master_bedroom_window opened (Log shows master_bedroom_window at 22:37:22).

Timestamp 22:37:28: front_door_lock state changed to Unlocked (1) immediately after the window opening.

Lack of explicit 'Manual' vs 'Auto' source distinction in the final lock event compared to earlier clear 'Manual' events.

Check raw logs for 'front_door_contact_sensor' readings around 22:37:28 to see if the door was already physically open before the lock command.

Verify if any 'manual touch' events or app usage timestamps coincide with the 22:37:28 lock unlock command to confirm authorization.

Cross-reference 'master_bedroom_occupancy' sensor data between 22:37:22 and 22:37:28 to determine if anyone was inside the room when the window was opened and door unlocked.

Check 'entrance_occupancy' sensor to see if a new entity entered the house immediately after the door unlocked at 22:37:28.

FG-03-FP: 烟雾报警器自检触发CO检测

All observed events are consistent with normal household activities, including routine smoke detector testing and authorized door/window operations by residents.

Explanation: The 'smoke detected' state was confirmed to be a self-test initiated at 07:13:00 and completed successfully by 07:13:30, ruling out a fire risk.

Explanation: The manual lock operation at 08:40 occurred after occupancy was already recorded in the entrance (since 07:14), indicating an internal resident unlocking the door (e.g., for mail or pet access) rather than unauthorized entry.

Explanation: Window covering adjustments at 12:27 and 13:55 correspond directly with verified occupancy events in the bedroom and living room, confirming human presence and control rather than tampering.

[2026-06-23T07:14:05] entrance_occupancy | OccupancySensing.Occupancy = 1

No action required; system status is normal.

Check if the Manual Lock operation at 08:40 was authorized via a specific user ID or remote control app log.

Verify if any motion sensors in the entrance hallway or outside the bedroom were active during the window manipulation events (12:27 - 13:55).

Confirm the timestamp of the 'SelfTestComplete' event relative to the COState change to ensure no real smoke was present after the test cycle.

有人在卫生间正常使用中触发，且短时间内恢复为 false

The sequence of events represents normal resident behavior where the door was manually locked upon departure and automatically unlocked upon return, with no signs of intrusion or system failure.

Explanation: Occupancy logs show the house is empty at night (00:00-05:30) and populated during the day, consistent with a sleeping/waking pattern.

Explanation: At 06:50:06, the resident manually locked the door before leaving; the subsequent 'Auto' unlock at 06:50:17 occurred while the door contact sensor registered an open state (True), indicating the resident had already exited and the auto-unlock was likely a smart-home feature triggered by proximity or a scheduled routine, not an external breach.

Explanation: A manual re-lock occurred at 08:34:00 after occupancy sensors detected presence in the kitchen, confirming user control and security restoration without any forced entry indicators.

Explanation: No alarm triggers, sensor malfunctions, or contradictory timestamps exist to support the anomaly hypothesis.

Continue monitoring for consistency in daily patterns.

Ensure smartphone geofencing settings are verified if automatic unlocking relies on it.

Occupancy sensors report '0' (empty) for all rooms at 00:00 and 00:30, which is expected if the resident is asleep or out, but combined with high daytime activity, it doesn't inherently contradict normal behavior unless the timestamps imply long absences during active periods.

High frequency of room activity (1855 events) contradicts a scenario where the house has been abandoned or broken into for a long duration without detection.

Manual locking events confirm user control over the door state.

Sleep disturbance or irregular sleeping pattern given multiple wake-up/check occurrences.

Multiple door interactions early morning (06:50) and late night/early morning (20:36) could indicate restlessness.

Window adjustments in bedroom (opening/closing) late at night (14:10, 20:36).

Room activity distribution is balanced across all rooms, suggesting functional use rather than panic or confusion.

No motion spikes or alarm triggers associated with these times.

Verify the source IP/MAC address of the 'Auto' unlock command to determine if it originated from the homeowner's mobile app or an external device.

Check the exact timestamp difference between the 'Auto' unlock and subsequent door lock events to see if there was a forced re-locking attempt.

Cross-reference the 'Auto' unlock event with the proximity signal from the homeowner's smartphone GPS to confirm they were nearby.

Review video footage (if available) around 06:50 and 20:36 to visually confirm who entered/exited and whether the door remained secure.

WD-03-FP: 住户外出但开了自动浇花系统

漏水传感器触发后在短时间内（3分钟）恢复为false，而非持续触发超过10分钟

The rapid manual lock followed immediately by an automatic unlock within 4 minutes at 06:58, combined with a door contact sensor detecting the door as open during this interval, indicates a system malfunction or false positive rather than human behavior.

Explanation: At 06:58:07, a manual lock command was issued and the state changed to Locked (2).

Explanation: However, at 06:58:10, the front_door_contact sensor reported the door as OPEN (True), contradicting the locked state.

Explanation: Immediately after, at 06:58:11, the system auto-issued an unlock command and changed the state to Unlocked (1), suggesting the 'manual' lock event may have been erroneous or the lock mechanism failed to engage properly before triggering a safety override.

Explanation: Unlike the evening routine (H2) where occupancy was zero and no intermediate 'open' signal was logged, the presence of the 'open' contact signal at 06:58:10 confirms the door was physically compromised or the sensor logic is flawed.

[2026-06-02T06:58:10] front_door_contact | BooleanState.StateValue = True

Physically inspect the front door lock cylinder and handle to ensure they move freely and are not jammed.

Check battery levels on the smart lock and hub to rule out power-induced glitches causing false states.

Reset the lock firmware or reboot the associated device to clear any stuck states.

Multiple rapid state changes on the front door lock sensor within a short timeframe.

Check if there is any motion detected inside the house between 06:58:07 and 06:58:11.

Verify the source IP or device ID associated with the 'Manual' lock operation at 06:58:07.

Confirm whether the resident typically locks/unlocks the front door manually in the early morning hours.

Check for any other anomalous behaviors such as smoke alarms, water leaks, or unusual temperature spikes during this time period.

WD-03-FP: 住户外出但开了自动浇花系统

漏水传感器触发后在短时间内（3分钟）恢复为false，而非持续触发超过10分钟

The smart lock system is executing automated unlock commands at times when no occupants are present and no manual triggers occurred, indicating a device logic failure or sensor malfunction rather than human intrusion.

Explanation: At 06:50:18 and 20:36:14, the front door lock received 'Auto' source unlock commands (LockOperationType=0) that directly contradicted the resident's manual locking behavior seen minutes prior.

Explanation: Occupancy logs confirm the house was completely empty (all zones showing Occupancy=0) immediately before both auto-unlock events, ruling out an internal trigger like someone opening a door from inside.

Explanation: The sequence of events (Manual Lock -> Door Contact Closed -> Auto Unlock) demonstrates a system-level error where the automation routine incorrectly interpreted the state or triggered without valid input, posing a security risk by leaving the home unsecured unexpectedly.

[2026-06-03T06:53:10] kitchen_occupancy | OccupancySensing.Occupancy = 1 (Proving resident was absent during the 06:50:18 event)

Immediately disable all automated scheduling for the front door lock to prevent further unauthorized access attempts.

Perform a firmware update or factory reset on the smart lock module to clear corrupted logic states.

Verify the physical operation of the lock manually and check for interference with occupancy sensors or network connectivity issues causing false triggers.

Check authentication logs for the front_door_lock device to see if any valid user credentials were used during the auto-unlock events.

Verify network traffic logs around 06:50:18 and 20:36:14 to detect any external intrusion attempts or remote command injections.

Cross-reference occupancy sensor data in the entrance hallway immediately preceding and following the auto-unlock events to confirm no one was present inside to trigger an internal auto-unlock routine.

The resident exhibits highly erratic behavioral patterns including unexplained manual locking/unlocking cycles and rapid window state toggling while occupancy sensors report the house as empty for significant portions of the day.

Explanation: Occupancy logs show the house was empty (0) between 00:00 and 05:31, yet at 05:31 the bedroom light turned on and the window cover position was set to 0 (closed).

Explanation: At 06:56, a Manual Lock operation occurred immediately after the bedroom occupancy sensor reported presence (1), but just seconds later (06:56:11) an Auto Unlock followed, with no clear exit/entry contact event correlating to a standard routine.

Explanation: Between 12:23 and 14:02, while the bedroom was occupied, the window cover rapidly toggled from fully open (10000) to fully closed (0) without any corresponding change in lighting or other environmental context suggesting a deliberate action.

Explanation: These actions do not align with normal sleep/wake patterns or standard security routines for an elderly resident living alone, indicating potential confusion, cognitive decline, or external manipulation.

[2026-06-20T00:00:00] bedroom_occupancy | OccupancySensing.Occupancy = 0

Contact the resident via phone or smart speaker to verify their safety and location.

Request immediate visual verification via connected doorbell camera or room cameras if available.

Dispatch emergency services or a trusted neighbor to check on the resident's physical condition given the erratic behavior indicators.

Multiple rapid switchings between manual/automatic lock operations and highly irregular window states that do not align with typical sleep/wake patterns for an elderly person living alone.

Frequent Manual Lock Operations at 06:56 and 08:29 followed by Auto unlocks, suggesting potential tampering or confusion.

Bedroom window position toggling between fully closed (0) and fully open (10000) multiple times between 05:31 and 20:55 without clear occupancy correlation.

Smoke Alarm SmokeState transition from 1 to 0 indicates a false alarm or extinguished fire, but combined with other anomalies, warrants verification.

Check timestamped video footage or motion sensor logs around 06:56 and 08:29 to see if anyone entered/exited the entrance area.

Verify if the bedroom window motor was physically manipulated manually versus automated control commands.

Review audio logs from the kitchen around 08:59 for any sounds preceding the smoke alarm alert.

Cross-reference the 'Auto' lock operations with system logs to determine if they were triggered by a smart hub or remote access.

开窗前住户先在同一房间活动并开灯，是主动行为

The system correctly interpreted a resident returning home as the trigger for auto-locking, confirming normal operation rather than an intrusion.

Explanation: At 06:55:02, a manual unlock occurred followed by occupancy detection at the entrance at 06:55:05 (OccupancySensing.Occupancy = 1).

Explanation: Immediately after occupancy was detected, the door locked automatically (OperationSource=Auto) at 06:55:05, indicating the user entered and the smart lock secured the door behind them.

Explanation: This sequence contradicts the 'lockout' hypothesis (intruder locking someone inside), which would show no interior occupancy or a struggle pattern, and aligns perfectly with standard morning arrival behavior.

Explanation: The subsequent events (lights on, window opening) further confirm this is a routine wake-up/arrival cycle.

[2026-06-23T06:55:05] entrance_occupancy | OccupancySensing.Occupancy = 1

Continue monitoring; no immediate action required.

Verify that the 'Manual' unlock source is consistently linked to internal user devices in future logs.

Raw signal strength (RSSI) and MAC address associated with the front_door_lock events at 06:55:02 and 06:55:05 to distinguish between local button press vs. remote command.

Timestamp precision logs to confirm if the 'Manual' unlock was actually executed by a human hand on the keypad/phone app or triggered externally.

The rapid lock/unlock sequence at 06:56 is consistent with a resident waking up, checking the door manually, and then triggering an automated routine (e.g., 'Away Mode') upon entering the kitchen, supported by the absence of intrusion indicators like forced entry or unauthorized motion.

Explanation: Occupancy logs show zero presence in the entrance area prior to 06:56:10, ruling out an intruder hiding outside or inside during the manual interaction.

Explanation: The sequence shows a resident entering the kitchen at 06:56:08 (occupancy=1), immediately followed by a manual lock (likely confirming entry) and then an auto-lock trigger within seconds, which aligns with a standard 'secure home' routine rather than tampering.

Explanation: Door contact sensors recorded normal opening/closing states without signs of forced entry (e.g., prolonged open state or repeated violent toggling).

Explanation: No motion sensor triggers were recorded in the hallway/entrance zone between the times of interest, further contradicting the hypothesis of an intruder attempting access.

[2026-06-21T06:56:08] kitchen_occupancy | OccupancySensing.Occupancy = 1

No entrance_occupancy triggers recorded before 06:56:08

Verify if the 'Auto' lock source corresponds to a scheduled 'Away' mode or proximity-based automation in the smart home settings.

Monitor for similar patterns on subsequent mornings to confirm this is part of the resident's established routine.

Possible 'baiting' scenario where an intruder attempts to breach the door while the system is monitoring, evidenced by repeated state changes without confirmed occupancy.

DoorState changes from 2 (Locked) to 1 (Unlocked) and back within minutes (06:56:10 - 06:56:16).

Multiple independent lock operations (Manual vs Auto) suggest conflicting control inputs or rapid tampering.

Zero occupancy readings in all rooms for extended periods (00:00 - 00:30) suggests the house was indeed empty, making internal disturbance unlikely unless the door was forced.

Rapid succession of Manual Lock followed immediately by Auto Unlock (or vice versa) at 06:56.

Frequent manual intervention on the front door lock without corresponding motion sensor activation in the entrance area.

Repeated toggling of bedroom window coverings late at night (20:53) when occupancy is zero.

Check raw video footage or doorbell camera logs for the time range 06:55 to 06:57 to verify if anyone approached the front door.

Verify the source ID of the 'Manual' lock operation; does it match a registered user device or a generic local trigger?

Review audio logs from the entrance/hallway for sounds of forced entry, glass breaking, or footsteps between 00:00 and 08:30.

Cross-reference the 'Auto' lock trigger logic: Was it triggered by proximity of a phone or a scheduled routine?

有人在卫生间正常使用中触发，且短时间内恢复为 false

Unexplained manual door unlocking and entry attempts occurred while the home was unoccupied for extended periods, indicating a potential break-in or attempted intrusion.

Explanation: Occupancy sensors reported '0' presence in all rooms from 00:00 to 06:57, yet manual lock operations occurred at 06:57 and 08:31.

Explanation: At 06:57:05, the front door contact changed to 'False' (open) immediately following a manual unlock, but no subsequent occupancy event recorded inside until 12:38, suggesting an intruder entered and exited without triggering interior sensors or the resident was absent during these specific interactions.

Explanation: The pattern of manual interaction during confirmed vacancy contradicts standard resident behavior (who would typically be present or use automated routines when away).

[2026-06-06T08:31:00] front_door_lock | Event: LockOperation(..., OperationSource=Manual)

Immediately contact local law enforcement to report a potential burglary attempt.

FG-04-FP: 低电量报警但传感器仍正常工作

No security threat detected; the sequence of events is consistent with a resident waking up early for ventilation, temporarily leaving the premises, and returning later.

Explanation: Occupancy sensors confirmed the home was empty starting at 00:00:00, but occupancy returned to the kitchen at 08:27:03, indicating a resident re-entered the house after the door lock manipulation.

Explanation: The 'Manual' lock operation at 07:03:03 immediately preceded by the front door contact opening (False state) and followed by closing (True state) indicates a person physically walked through the door rather than an external forced entry attempt.

Explanation: Subsequent activity shows normal residential patterns: cooking-related smoke alarm battery alert (resolved), window opening/closing for ventilation, and lights turning on/off, all consistent with authorized resident behavior.

[2026-06-27T07:03:05] front_door_contact | BooleanState.StateValue = False

Continue monitoring standard daily routines.

Verify that the smoke alarm battery replacement scheduled earlier was completed if not already done.

Motion sensor raw data timestamps between 05:31 and 07:03 to confirm if occupancy occurred inside the home during the window opening/door manipulation.

Smartphone/app log entries around 07:03 to determine if the 'Manual' lock operation was authorized by the owner's device or an external trigger.

Audio logs or camera feeds (if available) near the bedroom window and front door between 05:30 and 07:10.

Detailed breakdown of the SmokeCoAlarm.SmokeState=1 event at 11:51 to distinguish between actual smoke vs. battery alert confusion or false positive.

The sequence of events represents a resident waking up naturally after an overnight absence, confirmed by occupancy changes and sensor states consistent with authorized entry.

Explanation: Occupancy sensors remained at '0' (empty) from midnight through the early morning hours, confirming the house was unoccupied until 06:50.

Explanation: At 06:50:04, the manual lock operation occurred simultaneously with the door contact sensor registering 'False' (ajar), indicating the door was physically opened by someone inside.

Explanation: Immediately after the door closed (contact 'True'), the auto-lock engaged at 06:50:15, which is standard behavior for an internal user closing the door.

Explanation: The subsequent light activation at 05:40 and window adjustment at 06:50 align temporally with waking up and preparing for the day, ruling out forced entry.

[2026-06-04T06:50:04] front_door_contact | BooleanState.StateValue = False

[2026-06-04T06:50:06] front_door_contact | BooleanState.StateValue = True

Review video footage from the front door camera around 06:50 to visually confirm the presence of the resident exiting.

Verify that the smart lock's 'Auto-relock' timer setting is functioning correctly within normal parameters (e.g., < 30 seconds).

The specific timing of the door unlock (05:40) occurring while the house was officially registered as 'unoccupied' at 00:30 suggests either the system missed the wake-up event or the occupant was out earlier than recorded. Furthermore, the gap between manual unlock and auto-lock creates a vulnerability window that exceeds normal behavioral patterns unless explicitly programmed.

Multiple rapid state changes in bedroom window coverings within short intervals could indicate forced adjustment rather than manual operation.

[2026-06-04T00:30:00] living_room_occupancy | OccupancySensing.Occupancy = 0

Verify if there were any motion sensor triggers in the entrance hallway or bedroom between 00:30 and 06:50 to confirm absence vs. presence.

Check raw logs for 'front_door_contact' sensor state transitions around 05:40 to see if the door remained ajar.

Review audio logs or camera feeds (if available) for the period surrounding 05:40 to distinguish between authorized resident action and intrusion.

Confirm the programming logic for the 'Auto' lock source to ensure it did not trigger falsely due to sensor noise.

The front door was automatically unlocked at 20:48 while all occupancy sensors confirmed the home was empty, followed immediately by a bedroom light turning on and window coverings opening, indicating unauthorized re-entry.

Explanation: At 20:48:10, the front door lock changed state to 'Unlocked' via an 'Auto' command, yet every room (living, bedroom, kitchen, bathroom, entrance) reported Occupancy = 0 simultaneously.

Explanation: Immediately after the unlock (20:48:13), the bedroom light turned ON, and at 20:48:15 the window coverings opened to 100%, actions inconsistent with a resident who is already inside or asleep.

Explanation: No occupancy change occurred between 20:48 and midnight, suggesting the intruder moved directly from the entry point to the bedroom without triggering motion sensors in common areas, likely due to stealth or sensor limitations.

[2026-06-18T20:48:13] bedroom_light | OnOff.OnOff = True

Contact local law enforcement to report a suspected break-in.

Secure the premises and do not enter until authorities have assessed the scene.

Review video footage from exterior cameras and interior smart devices if available to identify the intruder's appearance and path of travel.

Bedroom curtains opened immediately after the door unlock event at 20:48:15, potentially indicating someone entering to observe inside.

Continued zero occupancy readings in living room and bedroom at 00:00 and 00:30 despite the door having been unlocked earlier.

Timestamp correlation between the front door unlock event and any subsequent motion sensor triggers in common areas (living room, hallway, kitchen).

Source ID of the 'Auto' lock operation at 20:48:10 to determine if it was triggered by a smart device command from inside the house or an external signal.

State history of the bedroom window contact sensor around 20:48 to verify if the window was open, closed, or if the 'opening curtains' action involved moving the window coverings vs. opening the window itself.

Power cycle logs for the main hub or specific devices to rule out false positives due to system resets.

The 'Auto' unlock events are normal automated behaviors triggered by the door being opened (contact sensor change), consistent with the resident's morning and evening routines.

Explanation: Analysis of the raw log at 06:50 shows a manual lock followed immediately by the front_door_contact changing from False (open) to True (closed) within 4 seconds, which is the standard trigger for an 'Auto' unlock upon re-entry or door closure in many smart home systems.

Explanation: Occupancy sensors confirm human presence in the bedroom starting at 06:52 and kitchen at 08:23, validating that the resident was active inside the home during these times rather than leaving.

Explanation: The sequence at 20:55 mirrors this pattern (door contact opens then closes) and coincides with the resident turning on bedroom lights and closing window coverings, indicating a routine departure or internal movement, not an intrusion.

[2026-06-03T06:52:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

Continue monitoring routine activities; no immediate intervention required.

Verify user settings if the homeowner prefers manual confirmation for all auto-unlocks, but current behavior appears safe.

[2026-06-03T20:55:16] front_door_lock | DoorLock.LockState = 1

[2026-06-03T20:55:31] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Repeated 'Auto' source unlocks (LockOperationType=0) at 06:50 and 20:55 without immediate preceding manual lock/unlock events, potentially indicating remote access, sensor malfunction, or automated bot activity.

High frequency of focus events (95) vs salient events (60) suggests significant background noise or rapid state toggling on key sensors (door/window).

Check for network connection logs associated with the front_door_lock around 06:50 and 20:55 to rule out remote commands.

Verify the configuration of the front_door_lock automation rules to see if 'Auto' unlocks are scheduled.

Review battery levels and signal strength of the front_door_lock and bedroom_window contact sensors to rule out false triggers due to hardware issues.

Cross-reference the occupancy sensor logs between 06:50 and 08:24 to confirm human presence when the 'Auto' unlock occurred.

有人在卫生间正常使用中触发，且短时间内恢复为 false

Irregular early morning door manipulation combined with a significant temperature spike suggests unauthorized access or an occupant activity inconsistent with the reported empty house state.

Explanation: The front door was manually unlocked at 06:57:06 and immediately auto-locked at 06:57:12, followed by a manual re-lock at 08:25:00. This sequence is highly irregular for a resident who typically wakes later, indicating either forced entry/exit or a deliberate test of the lock mechanism.

Explanation: Occupancy sensors reported 'Empty' (0) for all rooms from midnight until 06:58:00 when the bedroom light finally turned on. The sudden change to Occupancy=1 at 06:58 strongly implies someone entered the home between 06:57 and 06:58.

Explanation: A sharp temperature increase in the living room from ~2347 (at 03:35) to 2544 (at 08:25) correlates with the door events. While this could be normal heating, the timing coincides exactly with the anomalous door usage and occupancy change, raising suspicion of tampering or intrusion.

[2026-06-20T06:58:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

Review security camera footage (doorbell and interior) specifically between 06:57 and 07:00 to identify if anyone entered.

Check smart-lock mobile app logs to verify if the unlock command originated from a registered user device location or an unknown source.

Inspect the front door physically for signs of forced entry, scratches, or tampering with the locking mechanism.

[2026-06-20T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

[2026-06-20T00:00:00] bedroom_occupancy | OccupancySensing.Occupancy = 0

[2026-06-20T00:00:00] kitchen_occupancy | OccupancySensing.Occupancy = 0

Total room_activity count is high (22+23+20+10+20 = 95 events), contradicting a completely empty house narrative.

Standard daily routine where an elderly person might sleep through midnight sensors if they are stationary, but the specific timestamp of 00:00 being exactly zero is suspicious.

Front door Manual Unlock at 06:57:06 followed by Auto Lock at 06:57:12, then Manual Re-Lock at 08:25:00.

High activity counts in Kitchen/Living Room combined with explicit 'Occupancy=0' reports from those same rooms at 00:00 and 00:30.

Check if the 06:57:06 Manual Unlock operation source ID corresponds to a known family member's device or phone location.

Verify the exact timestamps of motion detection events in the Kitchen and Living Room to see if they align with the door operations or occur independently.

Review the camera feed (if available) or doorbell logs for the period between 06:57 and 08:25 to identify who entered/exited.

Cross-reference the 'WindowCovering.CurrentPositionLiftPercent100ths' changes with occupancy data to see if curtains were opened/closed while the house was reported as empty.
