The front door was manually unlocked by a resident at 17:21, occupancy sensors confirmed entry at 17:21:05, and the door remained open until it was automatically locked at 23:14, indicating an unauthorized occupant entered and stayed overnight.

Explanation: At 17:21:00, UserIndex=5 manually unlocked the front door (LockOperationType=1).

Explanation: Immediately after, at 17:21:05, the entrance_occupancy sensor registered presence (Occupancy = 1), confirming physical entry.

Explanation: The door remained in an 'open' state (implied by lack of contact sensor trigger) for over 6 hours until 23:14:20 when the front_door_contact sensor finally reported closed (StateValue = True).

Explanation: Subsequently, the system automatically locked the door at 23:14:21 (OperationSource=Auto).

Explanation: This sequence proves that while a legitimate user opened the door, an unknown entity or person entered and remained inside the premises until late evening.

[2026-06-06T23:14:20] front_door_contact | BooleanState.StateValue = True

Immediately alert local law enforcement regarding a potential break-in or trespassing incident.

Notify the household members via emergency contact protocols to verify their safety and location.

Preserve all video footage from exterior and interior cameras covering the time between 17:21 and 23:14.

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

Evidence strongly suggests an unauthorized entry via the front door followed by access to the master bedroom during late-night hours when no legitimate residents were present.

Explanation: At 22:26:10, occupancy was detected in the living room (a common area), indicating someone was inside the home.

Explanation: Three minutes later at 22:26:16, the master bedroom window was fully opened while occupancy sensors in all bedrooms remained empty, suggesting an intruder moved from the main floor to a private room.

Explanation: Immediately after, at 22:26:19, the front door lock state changed to 'Unlocked' (State=1) with an 'Auto' source, which contradicts normal behavior and likely indicates a forced breach or system override by an intruder rather than a resident.

Explanation: The sequence ends with the master bedroom light turning off at 22:26:23, consistent with an occupant leaving the room or the system detecting movement cessation.

Dispatch law enforcement immediately to investigate the property.

Notify the homeowner of the potential break-in and secure their personal safety.

Review camera footage for the front door and interior hallways between 22:26:00 and 22:30:00 to identify the suspect.

[2026-06-04T16:02:00] front_door_lock | DoorLock.LockState = 2

System automated locking failure or sensor glitch around midnight. An 'Auto' unlock event occurred at 00:00:00 followed by manual locks later, but the lack of subsequent movement suggests this was an isolated system event without human intervention or intrusion.

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

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

High activity count in entrance room (24) might suggest some interaction, but timestamps don't align with the anomaly window.

Simultaneous front door unlock (manual/auto confusion at 22:26:19) and master bedroom window opening (fully open at 22:26:16) with zero occupancy in common areas.

Door lock state changed to 'Unlocked' (1) immediately after the suspicious window opening event.

Check for motion sensor triggers in the hallway, master bedroom, or near the front door between 22:26:15 and 22:30:00.

Verify the source IP/MAC address associated with the 22:26:19 lock operation to determine if it was remote access or physical tampering.

Cross-reference smart home camera footage (if available) for the front door and master bedroom window at the timestamp of the anomaly.

Check if the window covering motor power consumption spiked significantly at 22:26:16 to confirm active opening vs. passive displacement.

通过门锁合法进入（有 LockOperation 事件+有效 UserIndex），不是通过窗户

The house was securely locked by a resident at 18:59 after normal evening activity; subsequent occupancy zeros are consistent with the family sleeping inside rather than being absent.

Explanation: Front door lock event at 18:59 confirms secure closure by UserIndex 5 (likely a resident) during typical evening hours.

Explanation: Occupancy sensors show '0' from 00:00 to 04:00, which contradicts an intrusion/vacancy hypothesis as it indicates no movement occurred while residents were likely sleeping in bedrooms.

Explanation: The presence of Occupancy=1 at 18:59:05 immediately after locking suggests a sensor lag or brief detection of the person standing near the door before fully exiting into a low-activity state, not an intruder entry.

All room occupancy sensors reported 0 between 00:00 and 04:00, ruling out total house vacancy.

The system logs indicate a routine evening security cycle with no signs of intrusion, tampering, or sensor malfunction; all events align with resident activity patterns.

Explanation: Door lock operations show a clear pattern: manual unlock at 18:18 (resident exit), followed by automated re-locking at 22:13 after occupancy cleared, consistent with standard home routines.

Explanation: The 'kids_room_window' report at 21:00 showing fully open (10000) is immediately contradicted by the log entry at 21:00:07 showing occupancy=1 and subsequent closing of other windows, indicating a transient state rather than a breach.

Explanation: All critical sensors (contacts, occupancy, locks) functioned normally without stuck states, drifts, or unexplained trigger sequences that would suggest forced entry or system failure.

The window covering event in the children's room is confirmed to be a routine occupant action (remote operation) following their entry into the house, with no signs of forced entry or unauthorized access.

Explanation: At 20:57:03, the 'entrance_occupancy' sensor triggered, indicating an authorized person entered the home immediately before the window event.

Explanation: Five seconds later at 20:57:07, the 'kids_room_window' covering opened to 100%, consistent with an occupant adjusting blinds upon entering the area.

Explanation: Subsequent logs show occupancy in the living room at 20:57:10 and the master bedroom later, confirming normal household circulation and securing routines, contradicting the hypothesis of an intrusion.

Explanation: No 'window_open' contact sensor events (indicating physical breach) were recorded, only motorized cover position changes.

[2026-06-04T20:57:03] entrance_occupancy | OccupancySensing.Occupancy = 1

Continue standard monitoring; no immediate response required.

Log the event as a verified 'normal evening routine' for future baseline comparison.

Window covering in kids_room opened/closed significantly (0 to 10000) late in the evening (20:57) while house appears to be securing itself (front door locked shortly before).

Absence of 'kids_room_occupancy' events around the time of the kids_room window covering change (20:57).

Check if any 'contact_sensor' events occurred for 'kids_room_window' indicating actual physical opening vs. just motorized cover adjustment.

Verify timestamps and logs for 'kids_room_occupancy_sensor' specifically between 20:00 and 21:00 to confirm no human presence.

Check 'entrance' and 'living_room' occupancy logs immediately preceding the 20:57 window event to see who might have been present to operate the cover remotely or manually.

System detected two distinct lock operations on the front door from different user indices within a 5-minute window while the home was empty, flagged as suspicious signals.

Explanation: Occupancy sensors confirmed all rooms (including entrance) were empty at the time of the events (14:20-14:30), indicating no legitimate resident was present to perform these actions.

Explanation: Two separate LockOperation events occurred at 14:20 (UserIndex 1) and 14:25 (UserIndex 2) on the same device with identical operation types, suggesting either automated testing, credential stuffing, or a system glitch rather than natural human behavior.

Explanation: The explicit 'suspicious_signals' flag in the evidence packet combined with the lack of corresponding motion sensor triggers for physical approach supports a non-standard event classification.

front_door_lock Event at 14:20:00 (UserIndex=1)

front_door_lock Event at 14:25:00 (UserIndex=2)

有人在卫生间正常使用中触发，且短时间内恢复为 false

All occupancy sensors are reporting a consistent zero state across the entire house while temperature sensors show active heating cycles, indicating a system-wide sensor failure or logic error rather than an empty house.

Explanation: Occupancy sensors for all monitored rooms (entrance, bedrooms, common areas) consistently report 0 over multiple timestamps from 00:00 to 04:00.

Explanation: Temperature sensors show continuous active heating cycles (rising from 22.6°C to 24.1°C), which implies the HVAC system is running based on expected occupancy schedules or user presence, contradicting the 'empty' status.

Explanation: The simultaneous total blackout of human detection despite environmental changes suggests a hardware fault, software glitch, or power loss in the occupancy network rather than genuine absence of occupants.

Consistent Occupancy = 0 for all 9 room sensors across all timestamps.

Active temperature readings showing rising heat levels (e.g., kitchen_temp_sensor at 04:00:00 shows 2410).

Immediately check local network connectivity and power status for all wireless occupancy sensors.

Verify physical battery levels of all motion detectors and replace if low.

Temporarily enable manual override or scheduled automation overrides until sensors are verified functional.

Evidence strongly suggests an intruder entered the home late at night (22:48), manipulated windows to simulate authorized activity, and left while the system reported empty occupancy.

Explanation: At 22:48, both the master bedroom and kids' room windows were opened to 100% while occupancy sensors in these rooms suddenly registered as occupied, contradicting the 'empty house' status seen earlier in the evening.

Explanation: Simultaneously, the front door contact sensor toggled from closed to open, followed immediately by an automatic unlock event, indicating a breach of the primary entry point coinciding with window manipulation.

Explanation: By 00:00 the next day, all occupancy sensors returned to zero without any subsequent lock/unlock events or motion detection logs for the intrusion timeframe, implying the intruder exited undetected.

Routine household activity with multiple residents: Multiple users (UserIndex 1, 2, 3) are present during the day and evening, performing normal locking/unlocking sequences and adjusting window coverings based on lighting/privacy needs.

Room activity counts across kitchen, living room, dining room, bedrooms suggest active usage.

Rapid lock-unlock cycle at 07:24 lacks clear context; simultaneous full opening of multiple windows at night contradicts typical 'closing up' behavior before sleep.

Zero occupancy reported for all rooms at 00:00 despite recent window manipulation.

Front door auto-unlock immediately after manual lock at 07:24:17/07:24:22

Multiple distinct users (UserIndex 1, 2, 3) accessing the front door within a short timeframe

Windows in Kids Room and Master Bedroom opened to 100% at 22:48, shortly after the last known door interaction

All rooms reporting empty occupancy at 00:00 following late-night window changes

Timestamps and IP addresses/MAC addresses associated with UserIndex 1, 2, and 3 on the front door lock

Motion sensor trigger logs for entrance, hallway, and living room between 22:00 and 23:00 to detect if anyone entered after windows were opened

Audio logs from front door sensors or smart locks around 07:24 to determine if someone forced entry or if it was a glitch

Window sensor state change rates: Did windows open gradually or snap-open?

有人在卫生间正常使用中触发，且短时间内恢复为 false

The system logs indicate a normal sequence of events where the front door was manually locked upon departure and subsequently unlocked automatically upon the family's return, with no evidence of unauthorized entry or sensor malfunction.

Explanation: At 18:11, the front door was explicitly locked (State=2) by manual operation after occupancy dropped to zero at midnight (00:00), confirming secure status during the night/early evening gap.

Explanation: At 22:13:30, the door state changed from Locked (2) to Unlocked (1) via an 'Auto' source. This is consistent with the standard smart-home behavior of unlocking the door when occupants are detected entering (indicated by master bedroom occupancy at 22:13:17 and dining room occupancy at 20:53).

Explanation: The window opening in the master bedroom at 22:13:19 occurred just before the auto-unlock, which is typical for preparing to open windows upon returning home, not indicative of an intrusion attempt.

LockOperation(LockOperationType=0, OperationSource=Auto) at 22:13:30 explains the state change without requiring an external unlock event.

Occupancy sensors detected presence (Master Bedroom 22:13:17, Dining Room 20:53) immediately preceding the auto-unlock, validating the legitimate user context.

No action required; system is functioning as designed.

No security threats detected; all events align with authorized resident routines including window automation and manual door locking.

Explanation: Occupancy sensors confirm the home was empty from 00:00 until morning activity resumed at 06:13, consistent with a normal night cycle.

Explanation: The window event in the kids' room (closed at 06:10, opened at 20:41) is explained by the log showing light activation at 06:10 and later occupancy at 17:45, indicating automated or scheduled behavior rather than forced entry.

Explanation: All door lock operations are explicitly tagged as 'Manual' with valid UserIndices (1 and 2) or 'Auto', occurring during times of confirmed resident presence, ruling out unauthorized intrusion.

Front door lock events show OperationSource=Manual with UserIndex=1/2 at 19:01-19:06.

Kids room window state change coincides with light activation at 06:10 and subsequent daytime occupancy logs.

Early morning window closure and door locking were caused by a resident waking up to adjust blinds before leaving for the day, confirmed by subsequent occupancy and light usage patterns.

Explanation: Occupancy sensors show all rooms empty from midnight until 06:33, but an occupant enters the master bathroom at 06:33, indicating the house is not empty.

Explanation: The window event at 06:31 was immediately followed by lights turning on (06:31:08) and off (07:25:25), consistent with a person physically interacting with the room upon waking.

Explanation: Crucially, occupancy in the kids_room turns ON at 07:26:00, just after the door is locked manually (07:25:32) and auto-locked (07:25:41), proving a resident was inside the home during these events, ruling out unauthorized entry.

Check motion sensor logs for kids_room between 06:00 and 07:30 to determine if a person entered the room before the window was reported closed.

Verify the source UserIndex of the 06:31 window event vs the 07:25 door lock event to see if they belong to the same household member or an unknown entity.

Review camera footage (if available) for the entrance hallway and kids' room during the 06:00-08:00 window.

Unauthorized entry confirmed at 22:19 indicated by an auto-unlock event coinciding with a door opening signal and occupants entering the bedroom.

Explanation: At 22:19:28, the front_door_contact sensor changed to True (open), indicating the door was physically opened from the exterior.

Explanation: Immediately at 22:19:29, an Auto-source LockOperation occurred while the door was open, which is inconsistent with authorized user behavior after hours.

Explanation: Occupancy sensors registered presence in the master bedroom starting at 22:19:18, and the window covering was raised shortly after at 22:19:26, confirming someone entered the premises.

[2026-06-03T22:19:18] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

Dispatch security personnel or emergency services immediately to investigate the scene.

Secure the perimeter and preserve digital evidence from smart home logs.

Contact local law enforcement to file a report regarding unauthorized entry.

[2026-06-03T06:28:17] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 0

Sequence of events suggests a forced entry or tailgating scenario where the door was unlocked from outside (or internally triggered auto-unlock) coinciding with curtains being raised.

Check `front_door_contact_sensor` state history between 22:15 and 22:25 to confirm if the door was physically opened from the exterior without an authorized unlock command prior to the 22:19:29 timestamp.

Verify `master_bedroom_occupancy_sensor` and `kids_room_occupancy_sensor` status around 22:19 to see if sensors registered movement consistent with someone entering through the windows or manipulating them.

Cross-reference `UserIndex` logs for UserIndex 1 and 2 to ensure they were not present on-site at 22:19 to rule out internal automation errors.

The log indicates normal household activity with authorized user interactions and no signs of intrusion or system malfunction.

Explanation: The front door unlock at 07:47 was immediately followed by a contact sensor reading False (open) for ~9 seconds, then True (closed), confirming physical access rather than a stuck lock or forced entry attempt.

Explanation: The second manual lock event at 16:32 is explicitly attributed to 'UserIndex=5', indicating an authorized resident action, not unauthorized tampering.

Explanation: The window covering changes in the kids' room (06:45 close, 20:52 open) correlate perfectly with light state changes (lights on before closing, lights off before opening) and occupancy data showing residents present, ruling out forced ventilation or hidden intruder testing.

Explanation: Nighttime logs show zero occupancy until morning wake-up times, consistent with standard sleep patterns and security arming routines.

Check if the 07:47:31 unlock was initiated by an external smart home app vs. physical key usage.

Verify the timestamp correlation between the kids' room curtain change and any corresponding motion sensor triggers or audio anomalies.

Review user index '5' associated with the 16:32:00 lock event to confirm authorized identity.

Cross-reference contact sensor data for the entrance door to ensure it wasn't held open longer than expected during the 07:47 interaction.

WD-02-FP: 洗碗机正常排水溅到传感器

The system indicates an empty house due to a scheduled maintenance period or automated cleaning cycle where human motion is not present, and the temperature rise is consistent with passive heat accumulation rather than active cooking.

Explanation: All occupancy sensors report '0' consistently from 00:00 to 04:00, which aligns with typical off-peak hours when residents are away.

Explanation: The absence of any 'OccupancySensing.Occupancy = 1' events contradicts hypotheses suggesting intruders or tailgaters, as a person entering would trigger at least one sensor (e.g., entrance).

Explanation: Temperature readings show a gradual increase (2262K -> 2392K) typical of indoor environments cooling down after evening use or slight solar gain, without the rapid spikes associated with active cooking appliances.

Explanation: The lack of specific actuator events (like stove ignition or lock engagement) in the provided log snippet further supports the conclusion that no humans are interacting with devices.

Persistent Occupancy=0 across all rooms including entrance for 4+ hours.

No manual interaction logs (e.g., thermostat changes, appliance toggles) detected in the raw excerpt during the observed window.

Continue monitoring; no immediate intervention required.

Verify if a cleaning robot or maintenance schedule is active during these hours to confirm normal operational context.
