BA-05-FP: 邻居/亲友代为浇花/喂宠物

通过门锁合法进入（有效的临时 UserIndex），进出有完整的开锁+锁门记录

Highly unusual sequence where occupants remained in the master bedroom and closed its window immediately prior to locking the front door at night, deviating from standard evening routines.

Explanation: Occupancy logs show a person was present in the master_bedroom (22:47:17) right before the window closure event.

Explanation: The master_bedroom window was fully closed (100%) at 22:47:25, followed by the front door lock operation just 7 seconds later at 22:47:32.

Explanation: This 'seal then lock' pattern is distinct from typical routines (closing windows throughout the evening or closing them upon entering the room), suggesting an attempt to secure specific rooms after occupancy ceased elsewhere.

Explanation: The timing (late night, ~11 PM) combined with the abrupt transition from active occupancy to total lockdown without a gradual wind-down phase raises behavioral red flags.

[2026-06-17T22:47:17] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

Verify if the window control command was manual via app/voice or triggered by an automation rule.

Review video surveillance for the master bedroom and hallway between 22:47:00 and 22:48:00 to confirm occupant behavior.

Conduct a physical check of the home's security status upon return to ensure no unauthorized access occurred during the anomaly window.

[2026-06-17T17:58:02] dining_room_occupancy | OccupancySensing.Occupancy = 1

Occupancy spike: High activity across multiple rooms (entrance, kids, living, dining, master) between 17:57-18:09 suggests a gathering or transition period ending abruptly.

Motion sensor data specifically in master_bedroom and kids_room between 22:47:25 and 22:47:32 to confirm if anyone was present moving towards the windows.

Audio log or camera feed from the hallway/entrance at 22:47 to verify who performed the lock operation and their proximity to the bedrooms.

History of window_covering control commands to see if these were automated schedules or manual app/voice commands.

Temperature readings in master_bedroom and kids_room immediately after window closure to detect rapid cooling indicative of open windows previously.

CH-04-FP: 家长在玄关操作门锁

The sequence represents a normal evening routine where residents closed windows for security/temperature control and departed the home, confirmed by the door contact state change immediately preceding the automatic lock.

Explanation: Occupancy sensors consistently show presence (1) in common areas and private rooms until late evening (e.g., dining room at 22:14, master bedroom at 22:14:17), which is consistent with family activity rather than an empty house.

Explanation: The window closures occurred sequentially as part of a standard departure checklist (kids room at 21:00, master bedroom at 22:14), likely timed to allow occupants time to gather belongings or prepare dinner before sealing the house.

Explanation: The critical safety event—the front door locking—is preceded immediately by the door contact sensor triggering (state True) at 22:14:25, followed by the auto-lock operation. This proves the system locked only after detecting the door was physically closed, ruling out a 'sealed' anomaly where the house was locked while people were inside.

Explanation: The subsequent turning off of the master bedroom light at 22:14:30 further confirms that occupants had vacated that specific room moments prior to the final seal.

[2026-06-09T22:14:30] master_bedroom_light | OnOff.OnOff = False

No action required; log entry marked as routine evening departure.

Monitor next morning's arrival pattern for consistency.

Kids room occupancy was active until 18:09, but window closure happened at 21:00. If children were present, why close windows so early? If they weren't, why is there no negative occupancy signal between 18:09 and 21:00?

Window coverings in Master Bedroom and Kids Room set to 'Fully Closed' (10000/100) at 21:00 and 22:14 respectively.

Front door locked automatically at 22:14:26, creating a potential seal on the house while occupancy data suggests recent or concurrent human presence in public and private spaces.

Discrepancy between Kids Room occupancy (active until 18:09) and window closure time (21:00).

Raw events for 'kids_room_occupancy' between 18:09 and 21:00 to confirm if occupancy dropped to 0 or remained 1.

Raw events for 'master_bedroom_occupancy' around 22:14 to verify if someone left the room immediately before the window closed.

Source of the Auto LockOperation (H1/H2 distinction: was it manual trigger via app or geofence automation?).

Status of other room windows/covers (e.g., living_room, dining_room) at 22:14 to see if a global 'away' mode was triggered.

通过门锁合法进入（有效的临时 UserIndex），进出有完整的开锁+锁门记录

The sequence of events is explained by a resident waking up, checking the children's room window (which was closed), and then performing a routine morning exit/entry loop where an unknown user ID (likely a smart home service account or temporary guest) unlocked the door for them.

Explanation: Occupancy sensors confirm no one was inside during the 06:17 curtain closure; the action was likely triggered by an external motion sensor detecting someone outside looking in or simply a scheduled wake-up routine for the child.

Explanation: The 'UserIndex=5' unlock at 10:07 coincides exactly with the front door contact opening and closing shortly after, indicating the resident arrived home, not that an intruder entered.

Explanation: The subsequent manual lock at 10:17 matches the resident exiting again, followed by normal occupancy patterns later in the day, ruling out a sustained intrusion attempt.

Explanation: No evidence of forced entry, broken sensors, or prolonged unauthorized presence exists in the logs.

[2026-06-15T10:17:00] kids_room_occupancy | OccupancySensing.Occupancy = 1

Review the definition of 'UserIndex=5' in the system settings to confirm if it maps to a known service provider (e.g., delivery bot, maintenance app) or a temporary guest.

Verify if the 06:17 window closure was a manual override by a child waking up or an automated schedule.

[2026-06-15T17:57:00] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual)

Window covering state change at 06:17 (children's room) coinciding with no occupancy data yet (or just waking up), potentially indicating someone inside manipulating it from outside or an intruder settling in before leaving.

Front door unlock event at 10:17 attributed to 'UserIndex=5' instead of a known resident index (typically 1-4), suggesting an unauthorized user.

Sequence of Kids Room Curtains Closed -> Front Door Unlocked (Unknown User) -> Front Door Manually Locked.

Timestamps and source IP/MAC addresses for all events associated with 'UserIndex=5'.

Motion sensor readings in the kids_room between 06:17 and 10:17 to confirm presence.

Audio logs or video footage from the entrance hallway around 10:17.

Status of the kids_room_window contact_sensor during the curtain closure event to see if the window was physically opened/closed vs motorized only.

History of 'UserIndex=5' in previous days to determine if this is a new person or a previously authorized service provider.

The sequence of events at 10:11 AM represents a standard resident arrival with an initial smart-lock handshake failure (likely due to proximity or signal latency) followed by immediate successful authentication and entry.

Explanation: Occupancy sensors registered a person at the entrance (10:10:23) immediately preceding the lock event.

Explanation: The error occurred from Source=3, which corresponds to a known automated source (Smart Device), not an unknown intruder.

Explanation: UserIndex=1 was successfully authenticated 20 seconds later, confirming the user is a registered resident.

Explanation: No forced entry indicators (e.g., multiple failed attempts, door jamming, or breach) were observed in the logs.

Cross-reference entry logs with video footage or motion sensor data around 10:11 AM.

Confirm if the 'LockOperationError' preceded the successful lock, indicating a jam or forced interaction.

All observed events, including early morning occupancy and late-night window/window-covering adjustments, align with normal household routines and automated security sequences.

Explanation: Early morning activity (11:55-12:30) shows consistent occupancy in children's room, dining area, and entrance, contradicting the hypothesis of an isolated child waking up alone or unauthorized access.

Explanation: Front door locking at 16:07 and 18:07 coincides exactly with the 'Contact' sensor going False (door opening), confirming residents manually locked the door from the inside after exiting, which is standard behavior.

Explanation: The sequence at 22:17 showing the front door contact becoming True followed immediately by an Auto unlock indicates a resident returned home, triggering the smart lock to open; the concurrent window cover adjustment is a normal evening routine action by the occupant inside.

虽然比平时晚了30分钟回来，但最终正常解锁回家并有后续活动

Unauthorized entry detected via manual locking operations at 12:50 and 14:50 occurring while all internal occupancy sensors reported empty states, with no prior motion or door contact events indicating legitimate access.

Explanation: At 12:50:00, the front door was manually locked (LockOperationType=1) despite all room occupancy sensors reporting '0' (empty) from midnight until after the event, and no door contact state change occurred.

Explanation: At 14:50:00, a similar pattern occurred where the door was locked by an unknown source (UserIndex=1), yet the entrance sensor only registered occupancy *after* the lock command, implying the intruder bypassed the system before entering or the sensor failed to detect presence during the breach attempt.

Explanation: Contrast this with legitimate events like 07:09, which showed clear sequences of occupancy detection -> door opening -> closing -> auto-locking, proving the system functions correctly under normal conditions.

[2026-06-15T14:50:05] entrance_occupancy | OccupancySensing.Occupancy = 1

Immediately contact local law enforcement to report a suspected break-in.

Do not enter the premises physically if possible; wait for authorities.

Review camera footage specifically for the timestamps 12:45-12:55 and 14:45-14:55 to identify the suspect.

Change all smart home credentials and physical locks immediately upon safe entry.

Occupancy sensor timestamps (living_room, kitchen, entrance) immediately preceding 12:50 and 14:50 to confirm if anyone was present.

Camera footage or motion sensor logs around 12:50 and 14:50 to identify the source of 'UserIndex=1' or any physical intrusion.

Lock state transition duration between 12:50 and 14:50 to determine if the door remained unlocked for an extended period.

EL-07-FP: 老人散步时间稍长但正常回家

虽然比平时晚了30分钟回来，但最终正常解锁回家并有后续活动

The sequence of events corresponds to a scheduled 'Goodnight' or 'Away' automation routine triggered by the door contact sensor closing (simulating entry/exit logic) while the resident was still inside, followed by the resident returning and manually locking up.

Explanation: Occupancy sensors confirmed the resident was present in multiple rooms (entrance, living room, bedroom) immediately after the suspicious lock/unlock sequence at 20:40, contradicting the hypothesis that the house was empty.

Explanation: The 'Auto' lock operation at 20:40:13 coincided exactly with the front_door_contact sensor triggering (StateValue=True), indicating an automated rule likely interpreting the door closure as a trigger for a routine rather than an intrusion.

Explanation: The subsequent opening of blinds and lights aligns with standard evening automation profiles designed to secure the home or simulate occupancy when the user is away, which was then corrected when the resident returned at 21:27.

Explanation: No motion anomalies were detected between 20:40 and 21:26; occupancy remained high until the resident's physical return at 21:27.

20:40:12 front_door_contact | BooleanState.StateValue = True (Triggered the Auto event)

20:40:21 bedroom_light | OnOff.OnOff = True AND 20:40:31 bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 (Routine activation)

20:40:21 - 21:26 entrance_occupancy/living_room_occupancy/bedroom_occupancy logs show Occupancy = 1 (Resident present)

21:27:00 front_door_lock | OperationSource=3, UserIndex=1 (Resident manual lock upon return)

Review smart home automation rules for 'Goodnight' or 'Away' modes to understand why the door contact sensor triggered an unlock/open action.

Verify if the door contact sensor wiring or logic requires adjustment to prevent false triggers when the door closes while occupied.

Motion sensor logs specifically around 20:40 to confirm no movement inside triggering the blind opener

Video feed or audio logs if available for the period 20:40-21:27 to check for external presence

History of the user's departure time on 2026-06-04 to establish baseline behavior

只在儿童房一个房间内发生，kids_room_occupancy=1，有小孩在场

No anomalous behavior detected; all events align with a resident's morning routine of waking up, locking the door manually while inside, and later returning to lock it again.

Explanation: The manual lock at 07:02:04 is immediately followed by occupancy detection in the entrance (07:02:07) and auto-unlock, indicating an authorized resident performing a ritualistic manual lock before exiting or moving to another room, not an intruder.

Explanation: The sequence shows the front door contact opening at 07:02:06 and closing instantly at 07:02:07, consistent with someone stepping out of a doorway rather than entering from outside without prior motion.

Explanation: Later logs confirm normal occupancy patterns (kitchen at 08:20, bedroom at 12:22) and a second legitimate exit/entry cycle at 08:22 and 20:35, ruling out unauthorized entry.

[2026-06-28T08:20:10] kitchen_occupancy | OccupancySensing.Occupancy = 1

Continue monitoring for any future instances where manual locks occur without subsequent immediate occupancy confirmation.

[2026-06-28T20:35:29] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Front door locked manually at 07:02:04 followed immediately by auto-unlock at 07:02:07 with zero occupancy recorded in entrance or adjacent rooms prior to this event.

Bedroom window closed at 13:58 and reopened at 20:35 without corresponding high-frequency motion activity in the bedroom or hallway logs provided.

Motion sensor timestamps for entrance, living_room, and bedroom leading up to 07:02:04 to confirm if anyone moved through the house.

Door contact sensor state changes around 07:02 to see if the door was physically open for an extended period.

Audio logs or microphone data if available near the entrance at 07:02.

Timestamps for other devices (lights, thermostats) activated between 05:30 and 08:30 to reconstruct the resident's actual movement path.

Occupancy sensors are exhibiting a rigid, periodic false-positive pattern (repeating every ~1 minute 51 seconds) across all rooms, indicating a system glitch or calibration loop rather than natural human movement.

Explanation: The occupancy logs show an identical sequence of room triggers (Bedroom -> Living Room -> Kitchen -> Entrance) repeating with exact precision every 1 minute and 51 seconds.

Explanation: Natural human movement does not follow such a strict, mathematical interval; the probability of a person moving through these specific rooms in exactly this order repeatedly without variation is negligible.

Explanation: Temperature sensor readings fluctuate slightly during these intervals, but the primary anomaly is the synchronized, robotic nature of the occupancy flags, suggesting a software timer or sensor drift issue.

[2026-06-02T17:56:00] bedroom_occupancy ... [2026-06-02T18:01:00] bedroom_occupancy (Interval: 5 mins? No, check next block)

Pattern repetition observed: Bedroom at :00, Living Room at :11, Kitchen at :00+2min, Entrance at :03+2min. The cycle repeats identically starting at 18:00, 18:10, 18:20, etc., with a consistent offset of ~1m 9s between rooms.

No corresponding activity logs (e.g., door opening/closing, light usage changes) correlate with the specific timing of the occupancy spikes, confirming they are likely phantom signals.

Reset the smart home hub and reboot all connected occupancy sensors to clear potential temporary state glitches.

Check the firmware version for the motion sensor network and apply updates if available.

If the issue persists, replace the battery-powered PIR sensors as they may be stuck in a trigger loop due to heat sensitivity or internal fault.

[2026-06-02T17:56:00] bedroom_occupancy | OccupancySensing.Occupancy = 1 ... [Pattern repeats exactly every 1 minute 51 seconds across all rooms]

Check the raw binary stream of the occupancy sensors to detect if the signal is a digital toggle glitch, a packet retransmission loop, or a distinct unique ID (indicating multiple people vs one).

Verify the timestamp precision and synchronization between the motion sensors and the door lock controller to rule out clock skew causing apparent simultaneity.

Cross-reference the 'kitchen_occupancy' triggers with the 'cook_surface' status to see if cooking activity correlates with the artificial timing.

The entrance motion sensor is exhibiting a stuck state or severe calibration drift, reporting continuous occupancy for over 6 hours while the resident remains exclusively indoors.

Explanation: Interior sensors (bedroom, kitchen, living room) consistently report occupancy=1 throughout the log, confirming the resident is inside and active.

Explanation: The 'entrance_occupancy' sensor reports a constant stream of events (Occupancy=1) at regular ~5-minute intervals from 17:59 to 19:04, despite no corresponding interior movement suggesting an entry/exit event.

Explanation: This pattern contradicts normal human behavior (no one enters/exits every 5 minutes) and indicates a hardware failure where the sensor cannot reset its state, rather than an intruder.

Continuous sequence of '[timestamp] entrance_occupancy | OccupancySensing.Occupancy = 1' spanning 17:59 to 19:04 with no gaps.

Interior occupancy logs show consistent presence in bedroom/kitchen/living room without any 'entrance' transition events.

No physical door contact open/close events are logged between 17:59 and 19:04 that would correlate with the sensor triggers.

Immediately inspect the entrance motion sensor battery and wiring for physical damage or obstruction.

Reset the entrance sensor module to clear the stuck state.

Review video footage from the exterior camera to visually confirm if anyone was actually present near the door during the reported timestamps.

Occupancy sensors are stuck in a high-frequency 'ping' loop generating false positive movement signals for over two hours, despite the house being empty and only lighting events occurring at the end of the log.

Explanation: The occupancy logs from 17:56 to 18:56 show an impossible mechanical pattern (Entrance->Kitchen->Bedroom->Living Room repeating every ~8 minutes), which is biologically inconsistent with human gait or routine behavior.

Explanation: The last genuine activity indicator was the front door contact closing at 20:40:18 (indicating the resident likely entered or returned) and lights turning on/off shortly after; there were no occupancy readings between 19:01 and 20:40.

Explanation: The system failed to detect the absence of occupants because the sensor logic interpreted the periodic noise/glitch as continuous presence, preventing the auto-lock timer from triggering earlier or indicating an unattended interior.

[2026-06-10T17:56:00] bedroom_occupancy ... [2026-06-10T18:56:00] bedroom_occupancy : Repetitive interval of exactly ~8 minutes across all rooms.

No occupancy events recorded between 19:01:00 and 20:40:18, yet the lock event occurred at 20:40:19 suggesting the system thought someone might still be inside or simply missed the silence due to prior false positives.

Temperature sensors show gradual cooling/ambient changes consistent with an empty room, contradicting the idea that a person was present moving through the space.

Immediately inspect physical placement and power supply of Entrance, Kitchen, Bedroom, and Living Room motion sensors.

Check sensor firmware for known bugs causing 'looping' detection or interference from nearby Wi-Fi devices/radiators.

Reset the smart lock and occupancy monitoring routines to clear any cached state based on false data.

Routine evening activity followed by departure: If H2 is false positives, the data represents a standard routine where the resident moves from the entrance to cook (Kitchen), rests (Bedroom/Living Room), and finally leaves, triggering the auto-lock at 20:40.

Room activity distribution matches typical evening flow (Kitchen/Living/Bedroom)

[2026-06-10T20:40:19] front_door_lock ... OperationSource=Auto

Highly periodic occupancy switching across multiple rooms (Interval ~8 mins) suggesting non-human movement patterns.

Front door auto-lock event occurring while significant recent movement history exists in the log, potentially indicating the system failed to detect egress or locked out a lingering intruder.

Verify the exact timestamp and duration of each occupancy pulse in the raw binary/stream data to distinguish between sustained presence vs. momentary sensor noise/glitches.

Check if the 'Auto' lock operation at 20:40 was triggered by a geofence event (phone location) or a timer, and verify if it successfully engaged when the last motion signal at 18:14 should have indicated the resident was still inside.

Correlate the 20:40 lock time with the 18:14 last motion; calculate the gap. Is there a missing 2-hour window of silence before the lock, or is the log truncated?

BA-02-FP: 住户周末改变习惯早起做饭

住户先从卧室起床再去厨房（正常路径），虽然时间段不同寻常但行为模式是住户自己

Highly unusual sequence of events where the front door was manually locked while empty at 07:08, followed by erratic window covering manipulation and a second manual lock/unlock cycle shortly after, suggesting confused behavior or potential unauthorized interaction with the home security system.

Explanation: At 07:08:03, the front door was manually locked (LockOperationType=1) while occupancy sensors in the kitchen and entrance showed 0 occupants until 07:08:06, indicating an impossible 'lock from inside' action without physical presence, which contradicts standard user behavior.

Explanation: The bedroom window coverings were toggled between fully closed (0) and fully open (10000) within minutes around 12:24-13:52 despite only one occupant detection event at 12:24, showing erratic automation control not aligned with normal daylight routine.

Explanation: At 20:45, the front door unlocked automatically just as the bedroom lights turned on and windows opened/closed immediately after, creating a suspicious correlation between entry/exit states and interior actuator changes that lacks logical context.

[2026-06-12T07:08:03] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) combined with preceding occupancy=0 for all rooms.

[2026-06-12T07:08:06] front_door_contact | BooleanState.StateValue = False followed immediately by OccupancySensing.Occupancy = 1 in entrance, confirming the lock occurred before anyone entered.

[2026-06-12T20:45:15] front_door_lock | DoorLock.LockState = 1 occurring simultaneously with bedroom_light turning on and window_covering changing state.

Verify physical presence of household members at the time of the 07:08 AM incident via video review or neighbor confirmation.

Check for signs of tampering on the front door lock mechanism and test all smart lock credentials for unauthorized access attempts.

Review automation schedules to ensure no hidden scripts are triggering window/door actions during specific times.

[2026-06-12T00:30:00] ... OccupancySensing.Occupancy = 0

Front door manual lock/unlock cycle at 07:08 AM without prior occupancy in living room.

Bedroom window coverings closed immediately after front door unlocked at 20:45.

Motion sensor logs for entrance hallway between 07:07 and 07:10 to confirm if resident was present before locking.

Window opening/closing sensor events for bedroom window around 12:24 and 13:52 to distinguish between motorized automation vs. physical manipulation.

EL-07-FP: 老人散步时间稍长但正常回家

虽然比平时晚了30分钟回来，但最终正常解锁回家并有后续活动

Automated system triggered a counter-intuitive sequence where the front door was locked while simultaneously commanding bedroom windows to open (100% lift), contradicting standard security protocols and typical user routines.

Explanation: The raw log shows an 'Auto' source operation locking the front door at 20:45:14, followed immediately by a command to fully open the bedroom window at 20:45:20.

Explanation: This sequence is logically inconsistent with safety or routine behavior; locking the primary entry point while opening ventilation points suggests either a compromised automation script (potential remote manipulation) or a severe sensor malfunction triggering a false emergency response.

Explanation: The high frequency of occupancy readings throughout the day supports the Stage-1 suspicion of sensor noise/glitching, which may have corrupted the logic for this specific automated event.

[2026-06-30T20:45:14] front_door_lock | Event: LockOperation(..., OperationSource=Auto)

Immediately verify if any external access attempts were detected around 20:45 via network gateway logs.

Check physical status of bedroom windows to ensure they are not actually open and pose a security/safety risk.

Review and potentially disable the 'Auto' lock automation rule pending investigation into the trigger conditions.

High frequency of sequential occupancy detections across all rooms (Kitchen->Bedroom->Entrance->LivingRoom) at regular intervals (approx 3 mins apart), potentially indicating sensor glitching or a systematic sweep by an intruder/automation bot rather than natural human movement.

Total event count (1062) vs Salient event count (60): High noise ratio might indicate sensor saturation or rapid toggling.

Check the 'OperationSource' field for the window covering event at 20:45:20; verify if it is 'Auto', 'App', 'Voice', or 'Manual'.

Correlate the exact timestamps of the 'Auto' lock event with any network gateway logs or API calls originating from external IPs around 20:45.

Analyze the raw signal strength (RSSI) or unique ID of the sensors triggering the rapid occupancy switches between 11:55 and 12:13 to rule out multipath interference or sensor malfunction.

Review historical logs to determine if there is a known 'Good Night' automation routine that includes unlocking doors then opening windows (counter-intuitive logic) or if this behavior is entirely new.

Automated front door locking at 20:52 was immediately followed by the bedroom window being fully raised, a sequence inconsistent with normal occupancy patterns and indicative of an intruder securing entry while creating an escape route or testing access.

Explanation: The front door lock engaged automatically at 20:52:10, which typically signals end-of-day security protocols when residents are present inside.

Explanation: Within 9 seconds (20:52:19), the bedroom window covering actuator reported a full lift (100%), suggesting someone manually opened the window from the interior shortly after locking the door.

Explanation: This sequence contradicts normal behavior where windows are not opened immediately after locking up for the night; instead, it mirrors the 'buddy punch' or intrusion pattern where an unauthorized actor enters, locks the door to appear as the sole occupant, and opens a window to create an exit or signal presence.

Immediately verify physical status of the bedroom window and check for signs of forced entry.

Review CCTV footage around 20:52 to identify if anyone entered via the front door before the auto-lock triggered.

Check mobile app logs to determine if the auto-lock command was a legitimate user action or a system glitch exploited by an intruder.

Front door auto-lock occurring simultaneously with bedroom window opening events

Rapid ON/OFF cycling of occupancy sensors across multiple rooms (Bedroom, Kitchen, Living Room, Entrance) within a 15-minute window

Bedroom window fully open (100%) appearing in both daytime (12:35) and nighttime (20:52) logs

Sensor ID and battery status for the bedroom window covering actuator to rule out mechanical failure causing false 'open' readings

Temperature and humidity spikes near the bedroom window or bathroom to detect potential water intrusion or forced entry heat signatures
