The front door lock exhibited a critical logic failure where an auto-unlock command executed immediately after a manual lock, leaving the door unsecured while occupants were reportedly inside.

Explanation: At 06:50:06, a user manually locked the front door (State 2), which is consistent with normal exit behavior.

Explanation: However, at 06:50:12 (only 6 seconds later), the system automatically unlocked the door (State 1) without any corresponding 'unlock' event or proximity trigger logged in the raw data.

Explanation: This contradicts standard security protocols and suggests a firmware bug or sensor interference causing a false 'auto-leave' or 'return home' trigger.

Explanation: While occupancy sensors were '0' during midnight hours (likely due to lack of motion detection at night rather than absence of people), the daytime activity logs and light/window events confirm residents are present, making the automatic unlocking of the main entry point during their residence a significant safety gap.

Immediately review camera footage between 06:50:00 and 06:50:20 to rule out physical intrusion.

Check device firmware for known bugs related to auto-lock/unlock sequences and update if available.

Temporarily disable auto-lock features until the root cause is identified.

Evidence indicates unauthorized entry into the bedroom around 05:23, followed by the occupant exiting through the front door at 06:52.

Explanation: Raw logs show the bedroom window covering was opened (position 0) at 05:23:18 immediately after the bedroom light turned on at 05:23:08, while all occupancy sensors prior to this event were empty.

Explanation: Occupancy in the bedroom was first detected at 06:53:00, indicating someone entered the room between 05:23 and 06:52, likely via the window.

Explanation: The intruder exited the house through the front door at 06:52:09 (contact sensor toggled), which then auto-locked, creating a clear sequence of break-in and egress.

Explanation: A second incident occurred later in the evening (20:40) where the window was opened and the resident subsequently turned off the light, suggesting a recurring pattern or a false alarm that still warrants verification of physical damage.

Evidence indicates a successful or attempted break-in where the intruder opened the bedroom window, entered the house, manually locked the front door (potentially to hide entry), and then an automated system immediately unlocked it, suggesting a tamper-response trigger or a sophisticated bypass.

Explanation: Occupancy sensors recorded zero occupants in all rooms between 05:30 and 08:25, yet the bedroom window was opened at 05:30:12 and subsequently closed at 12:40:10 without any motion detection during the intermediate period.

Explanation: At 06:59:10, a manual lock operation occurred on the front door while occupancy remained zero; this is inconsistent with normal resident behavior who would unlock upon return.

Explanation: Immediately following the manual lock at 06:59:10, the door contact sensor registered 'open' (False) for 8 seconds before being re-locked via 'Auto' source at 06:59:19. This rapid sequence strongly suggests the door was forced open from the inside after being locked from the outside, triggering a safety automation to unlock it.

[2026-06-07T06:59:12] front_door_contact | BooleanState.StateValue = False (Door opened immediately after manual lock)

Contact local law enforcement immediately to file a report regarding potential burglary.

Dispatch security personnel to inspect the physical condition of the front door lock cylinder and the bedroom window frame for signs of forced entry or manipulation.

Review video footage from exterior cameras covering the time window of 05:30 to 07:00 to identify the perpetrator.

Routine resident activity involving cooking and cleaning in the kitchen and living room during daytime.

room_activity counts for kitchen (24) and living_room (22) are significant.

Lock operations at 08:28 and 20:48 may correspond to resident leaving/returning.

The specific timing of the lock operations (immediate manual lock followed quickly by auto unlock) suggests possible forced entry simulation or system glitch rather than standard routine.

Bedroom window opened/closed without occupancy detection (05:30, 14:06, 20:48).

Rapid sequence of Manual Lock -> Auto Unlock on the front door (06:59:10 - 06:59:19, 20:48:11 - 20:48:25), which deviates from typical user behavior.

Zero occupancy across all rooms while window states are actively changing.

Motion sensor raw event logs for the bedroom and entrance between 05:30 and 08:30 to confirm if any movement occurred before the first door interaction.

Door lock firmware logs to determine if the 'Auto' unlock at 06:59:19 was a scheduled automation trigger or a response to an external tamper signal.

Window cover motor logs to verify if the position changes were commanded remotely or triggered locally (potentially indicating physical access).

Timestamp correlation between the window state change at 05:30:12 and the subsequent door lock events to calculate the dwell time outside.

The bedroom window sensor is reporting extreme 'open' states (10000) multiple times while occupancy sensors confirm residents are present inside the room and house.

Explanation: Occupancy sensors explicitly report 'Occupancy = 1' in the bedroom at 08:27, 14:02, and 20:51, confirming residents are physically inside.

Explanation: Despite confirmed occupancy, the window sensor reports a value of '10000' (indicating fully open or error) at 12:29 and 20:51, creating a logical contradiction where an occupied room has an 'open' window state.

Explanation: The temperature logs show normal ambient fluctuations without signs of heat loss/gain anomalies that would accompany a genuinely open window, supporting the conclusion of sensor data corruption rather than physical tampering.

[2026-06-18T14:02:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

Calibrate or replace the bedroom window covering sensor immediately to restore accurate status reporting.

[2026-06-18T20:51:16] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Simultaneous 'Occupancy = 0' in Living Room and Bedroom while Bedroom Window Covering toggles between Closed and Open.

Window covering reported as '10000' (likely full open or error state) multiple times when no one is present in the house.

Timestamped logs for 'bedroom_contact_sensor' to verify if the physical window was actually opened/closed or if the sensor data is stale/corrupted.

Logs for 'bedroom_occupancy' events specifically around timestamps 12:29 and 20:51 to rule out missed detections.

Check 'front_door_lock' event sources to confirm if Manual vs Auto operations align with expected resident behavior patterns.

The front door unlocked automatically via 'Auto' source immediately after being manually locked, but subsequent occupancy logs confirm the resident was inside and later re-locked the door upon exit, ruling out an intrusion.

Explanation: Log entry at 06:51:07 shows the door state changed to Unlocked (State=1) with OperationSource='Auto' only 5 seconds after a manual lock event.

Explanation: Crucially, occupancy sensor data at 06:51:00 shows Occupancy=1 in the bedroom, and the door contact sensor toggled False/True indicating the door was physically opened by someone inside.

Explanation: The sequence of events (Manual Lock -> Auto Unlock -> Door Opened from Inside -> Later Manual Lock at 08:28) indicates the homeowner tested or interacted with the system internally, not that an intruder breached the premises.

Explanation: No motion sensors triggered outside the home, and no unauthorized entry attempts were detected.

[2026-06-29T06:51:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

Verify the configuration of the 'Auto' unlock trigger for the front door to determine if it is responding to internal motion, window sensors, or temperature changes erroneously.

Update firmware for the front door lock to rule out known bugs causing premature auto-unlocks.

[2026-06-29T06:51:07] ... LockState = 1 (Unlocked) via Auto shortly after manual lock

Check camera footage or motion sensor logs for the entrance between 06:50:00 and 07:00:00 to see if anyone approached the door when it unlocked automatically.

Verify the firmware version and configuration of the front_door_lock to ensure 'Auto' unlock sources are not misconfigured (e.g., triggered by rain sensors or false contact signals).

Cross-reference the timestamp 05:26:19 bedroom_window state change with motion data in the bedroom to rule out intrusion attempts through the window.

The elderly resident has been absent from the home since midnight with no motion activity and rising indoor temperatures, indicating a potential emergency or severe neglect.

Explanation: Occupancy sensors in all zones (kitchen, living room, bedroom, etc.) reported '0' starting at 00:00:00 and remained empty until 07:07:08.

Explanation: Indoor temperature rose steadily from ~22.8°C at midnight to ~25.1°C by early morning, consistent with an unoccupied house heating up rather than active occupancy.

Explanation: The manual door unlock at 08:26:00 is likely the resident returning unexpectedly late after being missing for over 8 hours, rather than an intrusion event given the lack of forced entry signs or staggered sensor triggers.

[2026-06-26T00:00:00] ... OccupancySensing.Occupancy = 0 (All Zones)

Temperature drift from 2279 (00:00) to 2512 (07:05) with zero occupancy

First re-detection of occupancy at 07:07:08 in kitchen, followed by manual lock attempt at 08:26

Immediately contact the resident via phone/mobile app to confirm safety and location.

If no response within 10 minutes, dispatch security personnel or emergency services to check on the elderly resident.

Elderly living alone context implies low probability of long-term absence without notification

No evidence of forced entry during this specific window in the provided logs

Manual unlock of front door at 08:26:00 (shortly after auto-lock cycle), suggesting possible unauthorized entry or resident confusion due to age.

Bedroom window coverings toggled rapidly (100% -> 0% -> 100%) between 12:39 and 20:51, inconsistent with normal behavior patterns.

Complete lack of occupancy signals across all rooms starting at 00:00:00, indicating the elderly resident may have left home unexpectedly.

Motion sensor raw data timestamps specifically around 08:26:00 and 12:39:00 to see if they preceded the window/door events.

Door lock state change duration and force metrics at 08:26:00 to distinguish between normal key-turn and forced jamming.

History of the 'WindowCovering' device commands to determine if the 0->100->0 changes were automated schedules or manual overrides.

GPS/Wi-Fi location history of the mobile device associated with the elderly resident to confirm departure time.

Evidence indicates a forced entry attempt where the front door was manually unlocked while the house was empty, followed immediately by an automatic re-locking triggered by a contact sensor breach.

Explanation: The system logs show the house was completely unoccupied (Occupancy=0) from 00:00 until 06:51:00.

Explanation: At 06:51:02, the front door lock was manually unlocked despite no occupant being present in the entrance or bedroom to open it.

Explanation: Crucially, at 06:51:04 the door contact sensor registered 'False' (door open), and at 06:51:13 the lock automatically re-locked, confirming the intruder failed to enter quickly enough or triggered the alarm/routine upon exit.

Explanation: Similar patterns occur later (08:27 manual unlock -> auto lock, 20:44 auto lock after contact change), suggesting repeated unauthorized access attempts rather than normal resident activity.

[2026-06-30T06:51:00] bedroom_occupancy | OccupancySensing.Occupancy = 1 (First sign of life before door event)

[2026-06-30T06:51:04] front_door_contact | BooleanState.StateValue = False

Immediately check physical security cameras for the front entrance to identify the intruder.

Contact local authorities to report the attempted break-in.

Inspect the front door mechanism and contact sensors for signs of tampering or bypass attempts.

The system shows no security anomalies; the reported 'zero occupancy' during the night was a sensor blind spot or delay, as confirmed by subsequent normal human activity logs and the absence of forced entry indicators.

Explanation: Occupancy sensors consistently reported '0' from 00:00 to 05:21, which contradicts the hypothesis of an intruder testing locks if one were physically present inside.

Explanation: However, at 06:57, standard manual locking/unlocking occurred followed immediately (within minutes) by kitchen occupancy detecting a resident ('1'), proving the house was occupied by a legitimate user after the initial period.

Explanation: The window operations at 13:50 and 20:40 align perfectly with the resident's presence detected in the same timeframe, confirming these are routine actions by the homeowner, not an intruder.

Explanation: There is no evidence of door force/torque issues, rapid lock cycling indicative of tampering, or simultaneous conflicting events that would suggest a sneak-in.

front_door_lock Event: LockOperation(LockOperationType=1, OperationSource=Manual) at 06:57:09 followed by kitchen_occupancy = 1 at 06:59:07.

bedroom_window position changes at 12:38 and 20:40 coincide directly with bedroom_light OnOff events and occupancy = 1.

No logs indicate high-torque lock overrides or alarm triggers between 00:30 and 05:21.

Verify PIR sensor calibration or placement in the living room/entrance area to address the prolonged zero-occupancy readings.

Confirm that the smart home automation logic correctly distinguishes between 'no motion detected' and 'house empty' to avoid future false alarms.

Regular daily patterns of locking/unlocking doors and adjusting blinds/curtains observed throughout the day (e.g., 05:21, 12:38, 20:40).

The high frequency of lock operations (multiple within minutes) and the specific timing of window adjustments relative to zero occupancy readings make this hypothesis weak compared to H1/H2.

Occupancy sensors reporting '0' across all rooms (living_room, bedroom, kitchen) at T=00:30:00 while door/window actuators are active.

Rapid succession of front_door_lock operations (LockState toggling between 1 and 2) within a short timeframe (approx. 2 mins) suggesting testing of locks or forced entry.

Bedroom window position changing from fully closed (0) to fully open (10000) and back multiple times while no one is detected inside.

Raw motion sensor PIR data to check for false negatives or blind spots during the 00:30:00 - 01:00:00 window.

Camera footage (if available) for the entrance and bedroom windows during the night hours to visually confirm if an intruder was present.

Door lock force/torque metrics to determine if manual overrides were used versus normal key/card operation.

Timestamp alignment between the door lock event logs and the window cover motor logs to verify simultaneity.

Kitchen smoke alarm triggered due to unattended cooking while the residence was completely vacant for over 5 hours.

Explanation: Kitchen cook surface turned ON at 01:11:00 while all room occupancy sensors reported 0 (vacant).

Explanation: Smoke alarm activated at 01:26:00 with no human presence in the kitchen or home until 06:31:06.

Explanation: House temperature continued rising significantly overnight without any cooling intervention, consistent with an appliance running unmonitored.

[2026-06-02T01:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

Inspect kitchen appliances and ventilation for fire residue or damage.

Review smart plug or circuit history to ensure automatic shutoff features were disabled.

Verify if a timer or 'away mode' automation was accidentally bypassed.

Inconsistent window state: Bedroom window reported fully closed (0%) at 06:38 but fully open (10000% mapped to open) at 21:51, while occupants were absent during the night. This could indicate post-entry tampering or sensor malfunction.

[2026-06-02T21:51:29] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

kitchen smoke alarm activation at 01:26 during unoccupied hours

Rapid manual lock operation immediately following an auto-unlock at 07:29

Bedroom window state change from closed to open between 06:38 and 21:51

Check raw logs for 'kitchen_occupancy' status exactly at 01:26:00 to confirm if anyone was present when smoke alarm triggered.

Verify 'front_door_contact_sensor' state changes around 07:29:14 to see if the door actually opened before being manually locked.

Cross-reference 'bedroom_window_contact_sensor' readings with 'window_covering' position data to ensure they match at 06:38 and 21:51.

Check 'kitchen_cook_surface' and 'dishwasher' logs to rule out appliance errors causing smoke alarm triggers.

System-wide occupancy sensor failure causing 'empty' readings during confirmed human activity periods, leading to false anomaly hypotheses.

Explanation: Occupancy sensors consistently reported '0' (Empty) at 08:36 and 12:26 when raw logs confirm lights turned on and people were present in the bedroom/living room.

Explanation: The apparent correlation between door/window events and empty rooms is an artifact of this sensor failure, not evidence of intruders operating in blind spots.

Explanation: Door contact sensors correctly detected opening/closing cycles (e.g., front_door_contact state changes), proving physical access occurred but was attributed to the wrong cause due to missing motion data.

Explanation: Window/curtain movements align perfectly with light activation (05:31, 12:26, 20:41), indicating automated or manual user routines rather than unauthorized manipulation.

The sequence of events indicates a user manually opening the front door (likely to exit or check) which triggered an automatic re-locking cycle, followed by normal morning occupancy; no signs of forced entry, intrusion, or system failure are present.

Explanation: Front door contact sensor logged 'True' (closed) at 21:59:37 immediately before the auto-unlock event at 21:59:38, confirming the door was physically closed and not left ajar.

Explanation: The log explicitly shows an 'Auto' source lock operation triggering a state change to Locked (2) shortly after the manual unlock attempt at 07:37 and again at 21:59, proving the locking mechanism functions correctly without requiring manual intervention.

Explanation: Occupancy sensors show zero activity from midnight until 06:39, with lights and window coverings closing automatically at 06:39-06:45, consistent with a resident returning home naturally rather than an intruder.

Explanation: No motion sensor activations were recorded in living areas during the night, and temperature readings remained stable, ruling out tampering or hidden presence.

Notify the user that the front door was unlocked at 21:59 but automatically re-locked by the smart lock system.

Advise the user to review their smartphone app logs to confirm if they intended to leave the house or check the exterior at that time.

The auto-source lock operation immediately following manual unlock might indicate an automated system attempting to secure the door, but it seems to have failed or been overridden if the state remained 'unlocked' until further action, though the log cuts off there. However, the lack of 'Occupancy' change suggests no one entered to trigger a different pattern.

Front door locked state changed from 'Locked' (2) to 'Unlocked' (1) at 21:59:38.

Bedroom window covering moved to fully open (10000/10000ths) at 21:59:34.

Zero occupancy detected across all monitored rooms starting at 00:00:00, confirming the home was empty during the period the door was potentially compromised.

Timestamps and duration of the 'Auto' source lock operation at 21:59:38 to see if it successfully re-locked the door.

Any motion sensor activations in the living room or hallway between 21:59 and 00:00.

Video feed metadata (if available) for the entrance and bedroom around 21:59 to verify human presence or tampering.

Check if the 'Auto' lock operation at 21:59:38 resulted in a final 'Locked' state or if the door remained open until morning.

The sequence of events is consistent with a resident's normal evening departure routine and subsequent morning arrival, supported by ambient temperature data ruling out a fire.

Explanation: Temperature logs show the kitchen temperature dropped from ~230°C (raw scale) at 21:50 to ~225°C at 21:55, indicating no heat source or fire existed during the smoke alarm trigger.

Explanation: The 'Auto' door unlock at 21:52:37 occurred immediately after the bedroom window opened at 21:52:30 and before lights turned on, matching the pattern of an automated security disarming sequence triggered by residents leaving the house.

Explanation: Morning logs confirm a similar pattern where the front door was manually locked at 07:10:12 and auto-locked at 07:10:18, validating that 'Auto' lock/unlock operations are standard system behaviors for occupancy changes.

Verify the sensitivity settings of the kitchen smoke detector if false alarms persist in future cycles.

Review homeowner manual to understand the specific logic behind the 'Auto' door unlock trigger relative to window sensors.

Simultaneous trigger of Kitchen Smoke Alarm and Bedroom Window Opening within 2 minutes.

Front Door Unlock via 'Auto' source coinciding exactly with the smoke alarm event time (21:51:00 vs 21:52:37 proximity suggests a coordinated sequence or sensor correlation issue).

Kitchen cook_surface activity logs between 21:45 and 21:55 to rule out cooking-related false alarms.

Detailed timestamps and sensor IDs for the 'Auto' lock operation at 21:52:37 to determine if it was a sensor-triggered relock or manual override misclassification.

火灾风险警报，建议住户检查该区域电器

A significant and sustained temperature spike in the kitchen (reaching ~250°C reading) preceded the smoke alarm trigger at 10:52 AM, indicating a severe fire hazard.

Explanation: Analysis of raw logs reveals a continuous temperature rise in the kitchen starting from midnight, increasing from 22.76°C to over 24°C by morning.

Explanation: At 10:50 AM, just two minutes before the smoke alarm triggered at 10:52 AM, the kitchen temperature sensor recorded a critical value of 253.6°C (assuming the unit is scaled by 10), which is physically impossible for ambient air and indicates a sensor malfunction or calibration drift due to extreme heat/fire conditions.

Explanation: The combination of an unexplained massive temperature excursion immediately preceding the smoke detection confirms a high-severity safety event requiring immediate attention.

[2026-06-29T10:50:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2536

Immediately dispatch emergency services to verify a fire condition in the kitchen.

Investigate the kitchen temperature sensor hardware for failure or exposure to direct flame/heat sources.

Review historical data to determine if this was a one-time sensor glitch or part of a recurring equipment failure pattern.

room_activity shows significant activity counts in kitchen (22), living_room (33), and bedroom (25) during the day

Check if any temperature spike or flame detection event preceded the smoke alarm trigger at 10:52.

Verify the state of the bedroom window contact sensor during the period the window covering was fully open to rule out bypass attempts.

Cross-reference the 'empty house' occupancy reports (midnight onwards) with utility usage logs or mobile device location data to confirm if residents are actually home.

A person entered the bedroom at night, manually opened the window coverings (simulating an entry or ventilation), and triggered the front door to unlock automatically shortly after.

Explanation: Occupancy sensors detected a person entering the bedroom at 23:04:12 while the house was otherwise empty.

Explanation: Immediately following occupancy detection (23:04:19), the bedroom window covering motor command set position to 10000 (fully open/lowered).

Explanation: Within one minute of the window event, the front door contact sensor tripped (True) and the lock executed an 'Auto' operation, suggesting a system response to the breach attempt rather than a manual user action from inside.

Explanation: The sequence (Entry -> Window Cover Open -> Door Unlock) indicates a coordinated security bypass or forced entry attempt, not normal residential behavior.

[2026-06-07T23:04:12] bedroom_occupancy | OccupancySensing.Occupancy = 1

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

Do not enter the premises until police have cleared the area.

Review video footage from cameras near the bedroom window and front door if available.

Inspect the physical condition of the window coverings and front door for signs of tampering or forced entry.

Door lock raw logs around 23:04 to determine if the 'Auto' unlock was triggered by an external doorbell, smart home schedule, or manual override after an attempted breach.

Window contact sensor logs for Bedroom and Living Room to verify if the windows were physically opened/closed or if only the covering motor moved.

凌晨2:30-2:40短时间内多房间连续活动 活动轨迹：客厅→厨房→玄关（像在搜索什么） 卧室全程无活动（住户在睡觉），这些活动不是住户产生的 注意区分：如果卧室先有活动再到其他房间，则可能是住户起夜

Evidence confirms a forced entry event where the front door was manually unlocked and physically opened during unoccupied hours (07:19), contradicting standard security protocols.

Explanation: Occupancy sensors reported the home as empty ('0') from midnight until early morning, indicating no residents were present to authorize access.

Explanation: At 07:19:17, the front door lock received a 'Manual' unlock command, which is inconsistent with typical resident behavior for that time slot given the prior vacancy.

Explanation: Crucially, immediately following the manual unlock at 07:19:17, the door contact sensor registered an opening state ('False') at 07:19:19, proving the door was physically breached rather than just manipulated.

Explanation: The sequence shows the door being re-locked automatically only after this unauthorized physical interaction, suggesting a potential break-in attempt or successful intrusion.

[2026-06-10T07:19:19] front_door_contact | BooleanState.StateValue = False

Immediately change all access credentials and smart lock PINs/codes.

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

Review historical camera footage of the entrance area if available to identify the intruder.

Multiple consecutive occupancy sensors reporting '0' (empty) between 00:00 and 01:30, coinciding with potential intruder activity windows if manual locks were tampered with.

Rapid succession of Manual LockUnlock followed immediately by Auto Unlock at 07:19, which deviates from standard user behavior patterns.

Timestamps and source IP/MAC addresses for all 'Manual' lock operations to identify the user/device initiating them.

Door contact sensor logs (front_door_contact) between 00:00 and 02:00 to verify if the door was actually opened physically despite the lock state.

Motion detection logs in the entrance hallway specifically around 00:00-01:30 to correlate with the lack of room occupancy reports.

System event logs for error codes or battery warnings on the front_door_lock during the 07:19 incident.
