Repeated unauthorized lock operation attempts followed by an alarm indicate a forced entry attempt while the residence was empty.

Explanation: Occupancy sensors for all rooms (including entrance) reported '0' (empty) during the attack window (17:11), ruling out accidental internal operation or residents inside.

Explanation: The attacker used 'OperationSource=3', which differs from the known 'Manual' (Source not explicitly defined but distinct from error patterns) and 'Auto' sources seen later in the log.

Explanation: A specific DoorLockAlarm(AlarmCode=3) was triggered immediately after four consecutive failed lock operations, confirming a mechanical breach attempt rather than simple malfunction.

[2026-06-18T17:12:00] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

Contact local law enforcement to report the attempted break-in.

Check physical condition of the front door handle and strike plate for signs of tampering or damage.

Review security camera footage (if available) for the 17:10–17:15 window to identify the intruder.

Temporarily disable remote auto-locking features until the cause of Source=3 is identified.

Evidence indicates an unauthorized entry into the residence while occupants were absent, characterized by forced window openings and sequential room access.

Explanation: Occupancy sensors reported '0' in all rooms from midnight (00:00) until morning (06:31), confirming the house was unoccupied during the evening incident window.

Explanation: At 21:02 and 22:13, windows in the kids' room and master bedroom opened sequentially despite zero occupancy, a pattern inconsistent with standard bedtime routines or automated schedules for that time of day.

Explanation: Corroborating evidence shows lights turning on in these specific rooms immediately preceding or coinciding with the window openings, followed by occupancy detection at 21:07 and 22:13, proving physical presence of an unknown actor.

Explanation: The sequence suggests the intruder entered via the unlocked/forced windows to conduct looting or inspection before the front door was manually locked at 07:32 the next morning.

Time-series gap: Occupancy=0 at 00:00 vs Window Open events at 21:02/22:13.

Immediate correlation: Light activation in Kids Room (21:02) and Master Bedroom (22:13) directly preceded by window actuation.

Occupancy confirmation: Sensors detected presence (Occ=1) in those specific rooms within minutes of the window opening.

Notify local law enforcement immediately with timestamps of intrusion events.

Change all smart home credentials, especially front-door lock codes and Wi-Fi passwords.

Review security camera footage for entrance and windows between 21:00 and 07:30.

Inspect physical damage to windows and doors for signs of forced entry or tampering.

Temporal Gap: Windows opened at 21:02 and 22:13, but occupancy shows 0 at 00:00. If residents were home to close windows at 06:31, where were they between 06:31 and 21:02? The sequence implies abandonment.

Sequence: All rooms show Occupancy=0 at 00:00 (midnight), yet windows are being opened at 21:02 and 22:13.

Front door lock state transition from Auto-Locked (22:13) to Manually Unlocked (implied by event log order near midnight) or vice versa without clear occupant presence.

Simultaneous opening of multiple windows (Kids, Master Bed) while the house is reported as unoccupied.

Water leak sensor activation in Second Bathroom at 07:41, occurring shortly after a manual door lock event at 07:32, suggesting potential tampering or access prior to the leak.

Timestamps and source IP/MAC addresses for all 'front_door_lock' operations between 21:00 and 00:00 to distinguish between owner and unknown actor.

Raw video feed or camera snapshots from entrance and living room between 21:00 and 00:00.

History of 'kids_room_window' and 'master_bedroom_window' actuators to confirm if they were forcibly opened or manually pulled.

Activity logs for the Second Bathroom water leak detector to determine if the leak was caused by someone entering (e.g., using the toilet) or a pipe burst due to freezing (less likely in summer June).

Motion sensor trigger history specifically for the hallway/entrance area around 21:00 and 22:13 to correlate with window openings.

The front door was manually unlocked while the house was unoccupied, remained open for exactly 8 seconds with no one inside detected, before automatically re-locking.

Explanation: Log shows a manual unlock at 07:40:20 followed immediately by an automatic re-lock at 07:40:28, creating an 8-second window where the door was open but the system reported zero occupancy in all rooms including the entrance.

Explanation: Contact sensor data confirms the door state transition: State=False (open) at 07:40:22 and State=True (closed) at 07:40:27, validating that the door physically opened during this gap.

Explanation: The sequence of 'Manual Unlock -> Occupancy=0 -> Auto Relock' is inconsistent with normal resident behavior (who would be present to enter or leave), strongly indicating a tailgating incident where an intruder entered unnoticed after the authorized user left.

[2026-06-04T07:40:22] front_door_contact | BooleanState.StateValue = False

Immediately review camera footage around 07:40 AM to identify if a second individual followed the homeowner out.

Check entryway cameras/mirrors to see if someone lingered outside the frame between 07:40:20 and 07:40:28.

Inspect the home interior for any signs of forced entry or items moved during the 8-second window, though risk is lower than a break-in attempt.

Check raw contact sensor logs for the entrance door to verify if the door remained open between 07:40:20 and 07:40:28.

Verify the specific motion sensor IDs used for 'Occupancy' events to ensure they cover the immediate interior perimeter of the front door.

Cross-reference camera footage (if available) or microphone logs around 07:40 AM and 20:51 PM to identify who operated the locks/curtains.

Check battery levels and last-sync timestamps for the front door lock and window covering actuators to rule out false positives from communication errors.

The sequence of events represents a standard evening routine where the home is being secured for the night (windows closed/opened as per schedule, door auto-locked upon entry), with no evidence of unauthorized access or malfunction.

Explanation: Occupancy logs show human presence in the kids_room at 22:27:05 immediately preceding the window and lock events, confirming authorized residents were present.

Explanation: The front_door_lock event at 22:27:19 explicitly states 'OperationSource=Auto', indicating an automated geofence or timer trigger rather than manual manipulation by an intruder.

Explanation: Temperature sensors show normal ambient fluctuations without signs of smoke alarms triggering (SmokeState=0) or fire-related spikes, despite previous battery alerts being resolved.

Explanation: No motion sensors detected activity in the entrance/hallway prior to the secure-mode execution, ruling out tailgating or forced entry attempts.

The smart lock exhibited a critical malfunction where it automatically unlocked the door immediately after being manually secured by the resident, creating an unsecured entry point.

Explanation: Resident manually locked the front door at 07:29:32 (LockState=2).

Explanation: The entrance contact sensor confirmed the door was closed/sealed (False) until 07:29:40.

Explanation: At 07:29:41, exactly 9 seconds later, the system triggered an 'Auto' unlock command (LockOperationType=0), changing LockState to 1 (Unlocked) without any recorded manual input or authorized geofence trigger visible in the provided logs.

Explanation: This sequence contradicts normal security cycling and indicates a firmware glitch or sensor false positive that compromised the physical barrier.

Immediately check the current status of the front door; if open, secure it physically and change the lock combination/firmware.

Review video footage from the time between 07:29:32 and 07:30:00 to verify no unauthorized entry occurred during the brief window of vulnerability.

Disable the 'Auto Unlock' feature or investigate the specific motion/geofence trigger logic causing this behavior.

[2026-06-29T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

The 9-second interval between a Manual Lock (07:29:32) and an Auto Unlock (07:29:41) suggests a possible breach attempt or sensor malfunction upon exit.

High frequency of room activity in the evening (Living Room: 16, Kids Room: 14) combined with the suspicious door event.

Check raw logs for `entrance_contact_sensor` status changes around 07:29:32-07:29:45 to see if someone re-entered the house immediately after the door was locked/unlocked.

Verify the specific logic/config of the smart lock's 'Auto' unlock trigger (e.g., motion sensor proximity, geofence exit/entry rules) to determine if it was expected behavior.

Review video footage (if available) or doorbell logs for the 07:29 timeframe to visually confirm if anyone approached or entered the property.

触发安全警报，临时禁用 Keypad 输入，通知住户

Repeated forced lock attempts followed by an immediate alarm trigger indicate a high-probability intrusion attempt or physical lock failure.

Explanation: The system recorded four consecutive LockOperationError events on the front door within 40 seconds (17:29:00-17:29:40), which is inconsistent with normal user behavior.

Explanation: A DoorLockAlarm was triggered immediately after this sequence of failures at 17:29:50, confirming the security protocol detected an anomaly.

Explanation: Occupancy sensors show no one inside the house at the time of the incident (entrance_occupancy=0, living_room_occupancy=0), suggesting an external actor attempted entry while the home was unoccupied.

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

Inspect the front door lock mechanism physically for signs of tampering, jamming, or mechanical damage.

Review video surveillance footage from exterior cameras around 17:29 to identify the suspect.

The cluster of lock errors and subsequent alarm suggests a malfunction or forced entry not typical of routine activity.

Window covering state change (fully closed) at 21:12 in children's room while other rooms show occupancy changes might be inconsistent with standard bedtime routines if no one is present to operate them.

Rapid succession of LockOperationError events (17:29:00 - 17:29:40) on the front door lock.

Immediate activation of DoorLockAlarm immediately following the error sequence.

Multiple failed operations suggest either physical interference with the lock cylinder/handle or electronic jamming.

Raw GPIO/I2C logs from the front door lock controller around 17:29:00 to check for voltage spikes, motor stall currents, or unusual button press patterns.

Contact sensor state history for 'entrance' room (front_door_contact_sensor) during the 17:29 incident to confirm if the door was physically opened despite lock attempts.

Smartphone/App authentication logs to verify if any manual unlock commands were sent from external devices (e.g., a neighbor's phone or a compromised account) prior to the alarms.

Motion sensor logs in the entrance hallway between 17:29:00 and 17:30:00 to detect if an intruder entered before the alarm fully triggered or if someone lingered outside.

SmokeCoAlarm 的 COState 变为 Warning 或 Critical

CO 报警是严重安全事件，不同于烟雾报警

紧急通知所有住户撤离，开窗通风，联系燃气公司

The Carbon Monoxide alarm triggered definitively while the entire house was verified to be unoccupied, posing an immediate safety risk due to lack of human presence.

Explanation: Raw logs confirm 'COState = 1' and 'Event: COAlarm()' at 17:02, indicating a specific gas detection event rather than just particulate smoke.

Explanation: Occupancy sensors for all rooms (living room, bedrooms, kitchen, etc.) report Occupancy=0 at 17:00 and 17:05, confirming the house is empty.

Explanation: An empty home with an active CO alarm represents a critical safety failure where no one is present to ventilate the area or evacuate, necessitating immediate professional intervention.

[2026-06-28T17:05:00] living_room_temp_sensor | TemperatureMeasurement.MeasuredValue = 2369

Immediately call emergency services or fire department to check for Carbon Monoxide levels.

Do not re-enter the premises until authorities declare it safe.

Check the battery status and calibration date of the living room CO detector once safe to rule out sensor malfunction if external readings are clear.

触发入侵警报，通知住户，记录事件

Evidence indicates a forced entry attempt or tailgating event where the front door was opened manually, triggering an automatic lock cycle while occupancy sensors were active.

Explanation: At 07:31:18, a manual lock operation occurred, but immediately at 07:31:20, the front door contact sensor registered as open (False), indicating the door was physically breached or held ajar.

Explanation: The system automatically unlocked and re-locked the door within 11 seconds (07:31:29), a behavior inconsistent with standard user departure routines and indicative of a security protocol triggered by the door being left open.

Explanation: Occupancy sensors confirmed presence in the master bedroom at 07:32:00, suggesting residents may have been inside during the breach or returned shortly after, making the window period critical.

[2026-06-03T07:31:20] front_door_contact | BooleanState.StateValue = False

Immediately review video footage from the front doorbell/camera for the time range 07:31:00 - 07:32:00 to identify if an intruder entered or if the door was accidentally left open.

Check the status of all doors and windows and ensure the home is fully secured before allowing resident re-entry.

Contact local authorities if any suspicious individuals are identified in the footage or if there is evidence of unauthorized access.

[2026-06-03T22:23:24] front_door_lock | DoorLock.LockState = 1 (Locked)

No occupancy sensors were active in bedrooms/living areas around 20:42-22:23 to confirm presence, but lack of activity doesn't rule out intruder movement through open windows.

Front door locked manually then immediately unlocked/relocked via 'Auto' source within 11 seconds (07:31:18 -> 07:31:29).

Kids room window fully opened at 20:42 while house appears unoccupied based on later logs.

Multiple manual lock operations late at night (16:08, 18:08) without corresponding exit events.

Check motion sensor logs specifically between 07:31:15 and 07:31:35 to see if any movement triggered the 'Auto' unlock/lock cycle.

Verify the state of the front door contact sensor immediately surrounding the 07:31 timestamp to determine if the door was actually opened before the auto-event.

Cross-reference camera footage or specific doorbell logs for the time range 07:31:00 - 07:32:00.

Check if the 'Auto' lock operation corresponds to a geofence exit trigger from a mobile device app rather than a physical sensor.

Multiple forced lock operation attempts and an alarm were triggered at the front door while the entire house was confirmed vacant.

Explanation: Occupancy sensors in all rooms (living, dining, bedrooms, etc.) consistently reported '0' occupancy from midnight through the incident time, confirming total house vacancy.

Explanation: The raw log shows four consecutive LockOperationError events followed immediately by a DoorLockAlarm on the front door between 06:35:00 and 06:35:50.

Explanation: The combination of repeated failed access attempts and a subsequent alarm during a verified empty state strongly indicates an external intrusion attempt rather than random internal malfunction.

Repeated failed lock attempts followed by an alarm occurred during a period of confirmed zero occupancy, indicating a high probability of forced entry or tampering.

Explanation: The system recorded four consecutive 'LockOperationError' events at 23:57, which is characteristic of physical manipulation or code guessing rather than user error.

Explanation: A 'DoorLockAlarm(AlarmCode=3)' was triggered immediately after the errors, signaling a security breach attempt.

Explanation: Simultaneously, all room occupancy sensors reported '0', including the entrance area, confirming no authorized residents were present to legitimately interact with the door.

Normal distribution of activities in kitchen, dining room, and bedrooms before 18:00.

Window covering adjustments at 20:43 and 22:12 consistent with bedtime routines.

The rapid succession of errors and alarms at 23:57 does not fit a standard routine pattern.

Low occupancy readings at midnight contradict the assumption that residents are actively managing the home state.

Check motion sensor logs for the hallway/entrance area between 23:56:00 and 23:58:00 to see if someone approached the door.

Verify the 'OperationSource=3' definition in device firmware to determine if it corresponds to an external keypad attempt, app command, or physical key.

Cross-reference camera footage (if available) or microphone audio logs near the entrance for sounds of forced manipulation.

Check if the front door contact sensor triggered an 'open' event immediately after the last error or alarm to confirm breach.

Repeated front door lock failure events followed by an alarm indicate a mechanical or electronic malfunction, not necessarily a successful intrusion attempt.

Explanation: Occupancy sensors recorded presence at the entrance at 10:42:21, immediately preceding the cluster of errors starting at 10:43:00.

Explanation: Five consecutive 'LockOperationError' events occurred within 40 seconds, indicating a system inability to complete the locking/unlocking cycle rather than a simple authentication failure.

Explanation: A specific 'DoorLockAlarm' was triggered at 10:43:50, confirming the system detected a critical fault condition during this high-activity window.

Explanation: Contrary to H1/H3, no physical breach evidence (e.g., contact sensor toggling to open state while locked) is present in the raw logs for the error window; the door likely remained closed but jammed.

Manually inspect the front door mechanism and hinges for physical obstruction or damage.

Reset the smart lock firmware/configuration to rule out software glitches causing repeated command loops.

Schedule professional maintenance for the door lock actuator if manual inspection reveals no external obstruction.

[2026-06-11T07:32:25] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Multiple children's room windows were closed at 22:26 while the main event cluster occurred earlier.

Potential intruder activity triggered a sensor loop or caused window closure via automation, coinciding with the door lock malfunction.

[2026-06-11T22:26:22] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

No occupancy sensors in living_room or dining_room reported presence during the critical error window (10:43), though this could be due to sensor blind spots or timing gaps.

Repeated 'LockOperationError' events (5 occurrences) within 40 seconds starting at 10:43:00.

Immediate trigger of 'DoorLockAlarm' at 10:43:50 following the errors.

Discrepancy between successful manual unlocks later in the day (15:57, 17:50) and the earlier failure cluster.

Raw state changes of the front_door_lock motor current/voltage during the 10:43 error burst to distinguish between jamming vs. authentication failure.

Timestamps of front_door_contact_sensor readings to determine if the door was physically forced open during the error window.

Logs for smart locks on other doors (if any) or network logs showing unauthorized access attempts to the lock IP address.

Correlation between the window closing events (20:43, 22:26) and motion sensor triggers to see if they are automated responses or remote commands.

火灾风险警报，建议住户检查该区域电器

The smoke alarm is stuck in an active state due to a sensor malfunction or drift, not a real fire, as temperatures are stable and well within normal ranges.

Explanation: All room occupancy sensors report 0 (empty), confirming the house is unattended and no cooking activity could have occurred recently.

Explanation: Temperature logs show kitchen temps rising slowly from ~22°C to ~24°C over several hours, which is consistent with passive cooling/heating cycles and completely inconsistent with a fire event that would cause rapid temperature spikes.

Explanation: The discrepancy between the 'SmokeState = 1' alarm at 19:42 and the physically impossible low temperatures proves the sensor is faulty rather than detecting smoke.

No security threat detected; the sequence of events aligns with a standard evening routine where family members returned home, adjusted privacy settings, and secured the house.

Explanation: Occupancy logs confirm that residents were present in the kids' room at 20:44:10 and the master bedroom at 22:44:13 immediately following the blind adjustments, proving the actions were performed by occupants inside.

Explanation: The 'Auto' unlock event at 22:44:23 occurred after the front door contact sensor registered an open state (22:44:22), indicating the lock automatically disengaged upon entry rather than being manipulated from the outside.

Explanation: The timeline shows normal daily patterns: morning lowering of blinds for sleep/privacy, daytime occupancy, and evening raising of blinds coinciding with re-entry and locking up.

The specific timing of raising blinds in the Kids' room at 20:44 (often too late for bedtime prep unless very young) and Master Bedroom at 22:44.

If H2 is true, why were the windows/blinds manipulated rather than just closed? The explicit motor commands suggest active intervention.

Rapid sequence of blind adjustments in different rooms (Kids, Master) within a short timeframe near midnight.

Manual lock operation at 22:44:00 immediately followed by an Auto unlock at 22:44:23, which is highly irregular for a standard 'go to sleep' routine.

Absence of occupancy data between the window events and the final lock state change could indicate movement via undetected vectors (e.g., through open windows).

Raw timestamped logs for `kids_room_occupancy` and `master_bedroom_occupancy` sensors between 20:00 and 23:00 to confirm if anyone was actually present when blinds moved.

Logs for `kids_room_contact_sensor` (window) and `master_bedroom_contact_sensor` (window) to see if they were physically open/closed during the blind movement.

Detailed event log for the `front_door_lock` around 22:44:23 to determine what triggered the 'Auto' unlock source (e.g., smart lock app command vs. sensor trigger).

Check `living_room` and `entrance` camera feeds (if available in raw logs as metadata) for any approach from outside during the window adjustment times.

Active smoke detection in the living room indicates a potential fire hazard requiring immediate verification.

Explanation: The raw log confirms a positive smoke alarm event (SmokeState = 1) at 13:33:00 in the living room.

Explanation: Temperature readings show a significant and sustained rise in both the kitchen (from ~22°C to ~24°C over several hours) and living room (jumping from ~23°C to 2482 at 13:35:00), indicating a thermal anomaly consistent with combustion or equipment failure rather than a transient false positive like steam.

Explanation: Despite occupancy sensors reporting '0' (empty house), the physical environment (temperature spike + smoke) presents an objective safety threat that overrides the lack of human presence data.

[2026-06-14T13:35:00] living_room_temp_sensor | TemperatureMeasurement.MeasuredValue = 2482

Immediately dispatch emergency services to the location for fire verification.

Alert all authorized household members via the smart-home notification system.

Do not attempt to manually investigate if the door is locked/unresponsive due to high temperature risk.
