FG-01-FP: 煲汤/慢炖（正常长时间开灶）

温度上升后稳定（不持续飙升），住户定期回来检查，烟雾传感器未触发

The manual door unlock at 18:08 was a routine exit performed by an occupant who was present inside the house immediately prior to the event.

Explanation: Occupancy sensors for the master bedroom and other rooms show 'Occupancy=1' at 18:06:00, confirming residents were inside before the 18:08:00 lock operation.

Explanation: The log shows the front door contact sensor going False (open) at 18:08:02 immediately after the manual unlock, consistent with someone walking out.

Explanation: The sequence of events (occupancy detected -> manual unlock -> door opens -> auto-lock later at night) follows a logical residential pattern rather than an intrusion attempt.

Explanation: The initial hypothesis suggesting an empty house at 18:08 is contradicted by the specific timestamped occupancy data from just two minutes earlier.

[2026-06-05T18:06:00] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-05T18:08:02] front_door_contact | BooleanState.StateValue = False

No immediate action required; this appears to be normal resident behavior.

[2026-06-05T07:17:37] front_door_lock | DoorLock.LockState = 1

The sequence shows doors being unlocked (Manual) at 18:08 while occupancy sensors for all rooms were empty at 00:00. If H2 is true, occupants must have left before 18:08 but returned to unlock the door at 18:08 manually, which contradicts the 'empty house' state or implies a loop. However, the strongest contradiction comes from the fact that at 18:08 the door was opened manually, yet no occupancy change was detected *inside* after 00:00. The critical issue is the time gap: Manual unlock at 18:08 vs Empty House report at 00:00. If they locked up at 18:08, why are they still inside? Or if they weren't inside, why manual unlock?

More precise contradiction: The timeline suggests an impossible sequence if interpreted as a single event chain without external factors. At 18:08, someone manually unlocked the door. At 00:00, everyone is gone. If they left at 18:08, the door should be auto-locked or remain locked until morning unless re-entered. The manual unlock at 18:08 combined with the subsequent 'empty house' status at midnight suggests either the residents left immediately after 18:08 (and the manual unlock was them leaving?), OR someone entered/unlocked it while they slept (high risk), OR the occupancy sensors failed.

Manual door unlock operation (LockOperationType=1) occurring at 18:08:00 while the home is known to be unoccupied by 00:00:00 (implying the resident might have been absent during the unlock, or the unlock happened while they were sleeping elsewhere).

Discrepancy between Manual Lock State Change (18:08) and Total Vacancy Report (00:00).

Check motion sensor logs specifically in the period between 18:00 and 00:00 to see if any movement occurred after the manual unlock.

Verify the specific room where the manual unlock took place relative to the user's last known location.

Check if the 'Manual' source at 18:08 corresponds to a legitimate resident's device/app usage or an external physical interaction.

Review contact sensor logs for the front door between 18:08 and 00:00 to see if the door remained open or was closed again.

只有1-2次错误（非连续多次），最终成功解锁且 UserIndex 是合法用户

The lock error was a transient system glitch followed immediately by a successful manual operation and confirmed door closure by the resident.

Explanation: At 10:04:00, a LockOperationError occurred from Source=3, but this was immediately resolved at 10:04:20 with a successful LockOperation from Source=3 (mapped to UserIndex=1).

Explanation: Crucially, at 10:04:22, the front_door_contact sensor registered StateValue=False, confirming the door was physically closed and secured shortly after the successful manual lock attempt.

Explanation: Contextual data shows continuous occupancy in the dining room around the incident time, indicating the event involved a known resident (User 1) rather than an unauthorized entry or tailgating scenario.

[2026-06-05T10:04:22] front_door_contact | StateValue = False

Monitor for recurrence of OperationError code 1 from Source=3 if it happens again.

No immediate security escalation required as the threat vector was neutralized by the resident.

WD-03-FP: 住户外出但开了自动浇花系统

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

The sequence of events indicates residents were present inside the home (occupancy sensor active in master bedroom) and opened a window for ventilation before locking the door via automation, consistent with normal evening routine.

Explanation: Occupancy sensors in the master bedroom and living room were active at 21:14 and 22:25, proving residents were physically inside the house during the window event.

Explanation: The 'WindowCovering' device type controlling the kids' room window is distinct from a direct contact sensor; the value '10000' likely represents a motorized blind fully raised (opening the window) or a specific protocol state for 'open', which aligns with the subsequent rise in temperature readings (2317 to 2351 between 21:30 and 22:30).

Explanation: At 22:25:24, the front door contact registered open (True), followed immediately by an automatic lock engagement (LockOperationType=0) at 22:25:25. This pattern confirms the system detected the door was being opened (likely by a resident returning or moving within the entryway) and secured it automatically, rather than detecting an unauthorized breach.

Explanation: No intrusion alarms, forced entry signals, or conflicting occupancy patterns (e.g., empty rooms while a window opens) were observed.

[2026-06-05T21:14:02] living_room_occupancy | OccupancySensing.Occupancy = 1

[2026-06-05T22:25:24] front_door_contact | BooleanState.StateValue = True

[2026-06-05T22:25:25] front_door_lock | DoorLock.LockState = 1

Monitor the 'kids_room_window' sensor history to confirm if future '10000' values correlate with temperature increases (ventilation) or remain static (sensor error).

Verify with residents if they intentionally opened the kids' room window for airflow around 9:13 PM.

[2026-06-05T07:29:32] front_door_lock | DoorLock.LockState = 1

Residents were present in the Master Bedroom and Second Bedroom until at least 22:25 (based on occupancy clearing at 00:00), making it plausible they are upstairs while someone is downstairs manipulating windows, or they left earlier than the main occupancy log suggests.

[2026-06-05T21:13:08] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Check the raw event stream between 21:13:08 and 22:25:25 for any 'DoorContact' open/close events on the front door or kids' room window contact sensor.

Verify if the 'WindowCovering' device type is a motorized blind or a physical window sensor; if it's a blind, '10000' might mean fully up (open window exposed) or fully down (closed). If it's a window sensor, confirm the state mapping.

Cross-reference audio logs or smart speaker transcriptions around 21:00-22:30 for alarms, shouting, or unusual noises.

Check GPS history or mobile device pings for resident locations between 18:14 and 22:25 to determine if anyone was actually home during the window incident.

FG-01-FP: 煲汤/慢炖（正常长时间开灶）

温度上升后稳定（不持续飙升），住户定期回来检查，烟雾传感器未触发

The sequence of events is consistent with residents managing the home environment (opening windows for ventilation) and performing standard security routines (locking/unlocking doors), without evidence of unauthorized entry.

Explanation: Occupancy logs show continuous presence in key areas (kids_room, dining_room, living_room, master_bedroom) during the critical times, contradicting the theory of an intruder entering after the resident left.

Explanation: The 'kids_room_window' opening at 20:50 occurred while occupancy was detected in that room and the living room, indicating a resident action rather than an external breach.

Explanation: The door lock state changes (Manual Lock -> Auto Unlock -> Manual Lock) align perfectly with a resident arriving home or moving between rooms to open/close curtains before securing the house again at night.

Explanation: No motion sensors were triggered in empty zones (like Living Room at 00:00-16:07) suggesting no hidden intruder was present.

Master bedroom window opened fully at 22:12, shortly after the final manual lock state change.

Check motion sensor logs for kids_room and living_room between 18:10 and 20:50 to see if anyone entered.

Verify the specific timestamp of the 'Auto' unlock event at 22:12:18 vs the manual lock at 18:10.

Cross-reference with camera feeds (if available) or doorbell logs for movement near the entrance between 18:10 and 20:50.

Check if the 'kids_room_window' opening triggered any alert or was part of a pre-set automation routine linked to the master bedroom.

The synchronized zero-occupancy state at midnight is consistent with a normal household sleep cycle where all residents have left their individual rooms or the house is empty during the night.

Explanation: Raw logs confirm occupancy dropped to 0 in all living spaces precisely at 00:00:00, which aligns with the evening lock operations (17:24, 17:29) indicating users left the premises.

Explanation: No motion events or temperature spikes indicative of intrusion are present between 00:00:00 and the next morning's readings; temperatures show natural drift rather than disturbance.

Explanation: The absence of re-entry lock operations and continuous zero-occupancy status supports the hypothesis of a standard overnight absence rather than a silent replacement.

front_door_lock event at 17:29 followed by immediate Occupancy=0 across all zones at 00:00:00

No motion sensor triggers or anomalous temperature changes detected during the 8-hour period

Continue standard monitoring; no immediate intervention required.

FG-04-FP: 低电量报警但传感器仍正常工作

虽然电池低但传感器仍然能正常检测烟雾（SmokeState变1又恢复0），说明设备没失灵

A confirmed fire event occurred in the kitchen while the house was unoccupied, indicated by smoke detection and a subsequent critical temperature spike.

Explanation: SmokeCoAlarm.SmokeState triggered at 12:03:00 and cleared at 12:13:00, indicating a real smoke event rather than a sensor glitch.

Explanation: Temperature logs show a dangerous spike from ~25°C to over 2500 (likely scaled value) between 12:00 and 12:10, confirming intense heat consistent with combustion.

Explanation: The house remained empty (occupancy=0) during the entire incident window, classifying this as an unattended fire risk.

[2026-06-27T12:10:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2521

Check raw temperature logs in the kitchen between 12:00 and 12:20 to confirm if there was a heat spike.

Verify if the smoke alarm battery alert ([11:53:00]) caused a false positive or degraded detection leading to the brief smoke reading.

Review the door lock status log around 12:00 to see if anyone exited immediately before the smoke event.

Inspect the specific logic of the occupancy sensors to determine if the '0' readings are due to calibration errors, battery drain, or a genuine lack of movement (which would be anomalous given prior activity).

A lock operation error occurred at the front door followed immediately by a successful lock engagement and the door contact sensor reporting 'False' (ajar/unlatched), indicating the system is currently compromised or malfunctioning.

Explanation: The log shows a sequence starting with LockOperationError at 11:19:00 from Source=3.

Explanation: This was immediately followed by a successful LockOperation at 11:19:20 from the same source.

Explanation: Critically, the front_door_contact sensor at 11:19:22 reports StateValue = False. In standard smart-home logic where True usually means 'secured/closed', False indicates the door is either physically ajar or the lock mechanism failed to engage despite the command.

Explanation: Since occupancy sensors are all zero, this suggests an unattended house where a potential breach attempt or mechanical failure left the entry point insecure.

[2026-06-20T11:19:22] front_door_contact | StateValue = False

Immediately dispatch security personnel or property management to verify the physical status of the front door.

Force a manual re-locking procedure if safe to do so, or change the lock credentials for Source=3 if it represents a compromised user/device.

Inspect the front door lock mechanism for physical damage or misalignment causing the sensor discrepancy.

FG-03-FP: 烟雾报警器自检触发CO检测

The CO sensor state change was a transient artifact of a scheduled smoke alarm self-test, not an actual carbon monoxide leak or intrusion event.

Explanation: All room occupancy sensors were '0' (empty) between 00:00 and 16:15, making unauthorized entry impossible before the first manual lock at 07:35:21.

Explanation: The front door log shows a consistent pattern of manual locking upon exit and automatic unlocking upon re-entry, with no signs of forced entry or tailgating.

Explanation: The 'COState = 1' signal occurred immediately after 'TestInProgress = True' and cleared exactly when 'SelfTestComplete()' was triggered, indicating the reading was a test circuit activation rather than a real gas detection.

Check raw acoustic data or gas sensor readings from the living_room_smoke_alarm between 20:35:00 and 20:35:30 to confirm if CO levels exceeded threshold or if it was purely a circuit test signal.

Verify the sequence of events in the entrance hallway to ensure no unauthorized access occurred before the first manual lock at 07:35:21.

FG-02-FP: 电暖器/取暖器正常使用

有人在房间且温度上升后趋于稳定（不是持续飙升），无烟雾报警触发

The sequence of events indicates normal household activity where residents manually unlocked the door to enter/exit or adjust settings, followed by automatic locking and secure closure at night, with no evidence of unauthorized entry.

Explanation: Manual lock/unlock operations (LockOperationType=1 then 0) occurred in rapid succession with 'Auto' source for the re-lock, consistent with a resident physically interacting with the door rather than an external breach.

Explanation: Door contact sensors returned to 'True' (closed) immediately after the manual unlock events (e.g., 07:32:34), confirming the door was shut securely by the system.

Explanation: Occupancy logs show zero occupancy in all rooms from midnight until early morning activity (06:48), ruling out late-night intrusions; subsequent window opening and occupancy changes align with waking up and preparing for the day.

Explanation: No motion sensor triggers were recorded in the entrance area between the suspicious-looking timestamps (16:15-17:54) to suggest anyone entered after a potential unlock.

Explanation: The final state at night shows all doors locked automatically and windows covering fully deployed, indicating a successful security routine.

Review user authentication logs if remote app usage is suspected during the 16:15-18:00 window, though physical interaction is more likely given the sensor data.

Continue monitoring standard daily patterns as no immediate threat has been identified.

第二人通过合法凭证解锁（不同UserIndex），且有合理时间间隔

The sequence of events at 07:34 represents a standard 'lock then unlock' cycle consistent with a resident exiting the house, not an intrusion.

Explanation: Occupancy sensors in the entrance and living room showed zero occupancy immediately before (07:34:14) and after (07:35:00) the lock event, confirming no one was inside during the cycle.

Explanation: The door contact sensor log shows a clear state transition from False (open) to True (closed) between 07:34:25 and 07:34:33, proving the door was physically opened and then closed by someone outside or just stepping away, rather than being forced open while locked.

Explanation: The subsequent automatic unlock at 07:34:34 aligns perfectly with a pre-set automation rule (e.g., 'Unlock if door is closed for X seconds') triggered by the manual lock, which is a common safety feature to prevent locking oneself out.

[2026-06-30T07:34:33] front_door_contact | BooleanState.StateValue = True

Log the event as 'Normal Routine - Resident Exit'.

Review user settings to confirm the 'Auto Unlock on Close' automation is active and functioning as intended.

Sequence of Manual Lock -> Auto Unlock within 1 minute at 07:34 AM without preceding 'Unlock' event from a recognized user context.

Rapid succession of door lock operations (Lock then Unlock) compared to other times which show consistent Manual Lock only.

Check if there was any motion sensor trigger in the entrance hallway or living room between 07:34:20 and 07:34:40 to confirm presence during the anomalous lock cycle.

Verify the 'OperationSource=Auto' at 07:34:34: Was this triggered by a proximity sensor, a scheduled automation rule, or a physical override?

Review the contact sensor logs for the front door around 07:34:23 to see if the door was actually opened before being locked again (false positive on lock state vs actual physical state).

Cross-reference UserIndex 1 and 2 with known resident profiles to ensure no spoofing or unrecognized accounts were used later that morning.

FG-04-FP: 低电量报警但传感器仍正常工作

A high-temperature event in the kitchen occurred while the house was unoccupied, triggering a transient smoke alarm detection.

Explanation: The house occupancy sensors confirm no one was present in any room between 14:00 and 14:25 (empty house condition).

Explanation: Kitchen temperature rose significantly to ~2478°C (likely sensor drift or specific unit scale indicating extreme heat) at 14:10, immediately preceding the smoke alert.

Explanation: The smoke alarm triggered at 14:14 and cleared automatically at 14:24, consistent with a small flare-up from an unattended cooking incident that self-extinguished or was vented.

Explanation: No human intervention is logged during the 10-minute duration of the hazard, classifying this as an unattended safety risk.

[2026-06-20T00:00:00] ... OccupancySensing.Occupancy = 0 (all rooms)

Dispatch a security officer or automated drone to visually inspect the kitchen for burnt food or active stove issues.

Reset the smoke alarm if it fails to re-arm automatically after the clear state is confirmed.

Review smart appliance logs for stove/burner activation timestamps around 14:00 to determine if a device malfunctioned.

The temperature sensors are reporting physically impossible values (2279°C to 2394°C) indicating a sensor failure or calibration error, while occupancy data consistently shows zero, supporting the normal hypothesis of an empty house.

Explanation: Occupancy sensors across all rooms report '0' consistently from 00:00 to 04:00, which aligns with the expected behavior for an unoccupied residential property during early morning hours.

Explanation: Temperature readings (e.g., 2279, 2281, 2394) are physically impossible for indoor environments and clearly indicate a hardware malfunction, stuck digital readout, or unit conversion error in the kitchen/living room sensors.

Explanation: Since the high numerical values in temperature logs are identified as erroneous rather than indicative of heat generation (fire), they do not contradict the conclusion that no occupants are present; therefore, no security threat exists.

The manual door lock at 18:20 correlates with high occupancy sensor readings in common areas just prior (18:16), indicating a resident exiting normally rather than an unauthorized entry or tailgating event.

Explanation: Hypothesis H2 suggested an anomaly based on the timestamp 18:20:00 alone, assuming empty rooms.

Explanation: Raw log evidence at 18:16:09 shows dining_room_occupancy = 1, proving a person was present immediately before the lock event.

Explanation: This confirms the manual lock operation at 18:20 was a standard exit action by an occupied resident, consistent with the pattern seen at 16:35 and 07:11.

Explanation: No signs of forced entry, rapid re-entry, or contradictory sensor data exist to support an intrusion hypothesis.

The events at 22:19 represent a standard automated smart-home routine (nighttime window opening for ventilation followed by automatic door locking) with no signs of forced entry or unauthorized access.

Explanation: Occupancy logs confirm the master bedroom was occupied just minutes prior (22:19:11), indicating an authorized resident initiated the actions.

Explanation: The raw log explicitly shows 'OperationSource=Auto' for the lock state change at 22:19:22, ruling out manual tampering or forced entry.

Explanation: The sequence of events (Window Open -> Door Auto-Lock) aligns perfectly with normal evening routines and contradicts the anomaly hypothesis of simultaneous multi-point intrusion.

Check for specific 'UnlockOperation' event type logs between 22:19:18 and 22:19:22 on the front_door_lock to confirm if an actor physically turned the knob or used a key.

Verify the source of the 'Auto' unlock at 22:19:18 (if any operation log exists) vs the manual lock at 22:19:22 to see if it's a single user cycle or two different actors.

Cross-reference the timestamp 22:19:22 with camera footage (if available) to verify if windows were opened manually or if the sensor triggered falsely due to wind/drafts.

Check if the 'KidsRoomWindow' and 'MasterBedroomWindow' open events are linked to a single user session or distinct sessions.

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

The sequence of events indicates normal household routines including morning departure and evening ventilation/cleaning, with no evidence of forced entry or tampering.

Explanation: The 'Auto' unlock at 07:17:34 immediately followed by the door contact sensor returning to 'Closed' (True) at 07:17:33 confirms a legitimate resident exited and closed the door, rather than an intruder bypassing a lock.

Explanation: The window opening in the kids' room at 21:04:10 occurred while occupancy was active in the dining room, and is consistent with evening ventilation or cleaning activities supported by similar window operations later that night in the master bedroom.

Explanation: The midnight occupancy zeros are explained by the house being empty during the night cycle, which is standard behavior; the daytime activity logs confirm residents were present earlier.

[2026-06-04T07:17:33] front_door_contact | BooleanState.StateValue = True

Continue monitoring normal operation.
No immediate action required.

[2026-06-04T17:42:00] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual)

[2026-06-04T06:36:13] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 0

Rapid sequence of door unlocking (Auto) immediately following a manual lock at 07:17:25/07:17:34, suggesting potential tampering or 'lock bypass' behavior.

Window in kids_room opened to full extent (100%) at 21:04:10, which is late evening but coincides with high occupancy elsewhere.

Multiple occupancy sensors reporting 0 at midnight despite high daytime activity counts, indicating either residents left early or sensors are failing/triggered incorrectly.

Raw GPIO or motor current logs for front_door_lock between 07:17:20 and 07:17:40 to verify if the 'Auto' unlock was a legitimate smart-home automation trigger or an external override.

Contact sensor logs for kids_room_window around 21:04:10 to confirm physical breach vs. curtain movement.

Motion detection timestamps and confidence scores for all rooms between 21:00 and 23:00 to correlate the window opening with human presence.

User authentication logs for UserIndex=5 at 09:19:00 to ensure it matches a known family member.
