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

An unauthorized entry attempt succeeded after a lock malfunction, occurring while the house was unoccupied and sensors were active.

Explanation: The house occupancy logs show all rooms empty (0) from midnight until 06:28 AM when residents woke up in the bathroom/bedroom, confirming low-occupancy status during the incident.

Explanation: At 09:01:00, a LockOperationError occurred immediately followed by a successful unlock at 09:01:20 initiated by Source=3 with UserIndex=1, indicating an automated or remote override rather than manual entry.

Explanation: Crucially, the front_door_contact sensor registered StateValue=False (open) at 09:01:22, physically confirming the door remained open despite the subsequent lock operation, validating the intrusion.

[2026-06-01T09:01:00] bedroom_occupancy | OccupancySensing.Occupancy = 1 (House empty prior to event)

[2026-06-01T09:01:22] front_door_contact | StateValue = False

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

Secure the premises and do not enter until authorities have inspected the property.

Change all access codes and review smart-lock security settings for 'Source=3'.

有人在卫生间正常使用中触发，且短时间内恢复为 false

The front door was locked automatically at night while the resident was still inside (occupancy detected) and shortly after the door opened from the inside, indicating a system error or unintended auto-lock rather than an intrusion.

Explanation: Occupancy sensors confirmed presence in the bedroom at 23:10:10 immediately preceding the lock event.

Explanation: The front door contact sensor triggered an 'open' state (True) at 23:10:24, just one second before the auto-lock command was issued.

Explanation: This sequence (door opens -> occupant likely exits room to close door -> system triggers auto-lock) suggests the resident accidentally left the house or the smart lock malfunctioned by locking out the user who had just exited.

Explanation: No evidence of forced entry, break-ins, or unauthorized movement; the pattern aligns with a household automation failure.

[2026-06-28T23:10:24] front_door_contact | BooleanState.StateValue = True

Check if the resident is safely outside or if they are trapped inside.

Review smart lock settings to disable 'auto-lock' during low-light hours or when occupancy is ambiguous.

Test the manual override function of the smart lock to ensure immediate re-entry capability.

开窗前住户先在同一房间活动并开灯，是主动行为

Evidence indicates an unauthorized manual unlock of the front door at 07:39 followed immediately by a suspicious auto-lock cycle while the house was vacant, with no subsequent entry/exit activity detected.

Explanation: The system log shows a manual unlock event (LockOperationType=1) at 07:39:12, which is highly unusual for a secure home unless authorized personnel are present or testing the lock.

Explanation: Immediately after the manual unlock, the door sensor triggered an automatic re-lock (LockOperationType=0, Source=Auto) within 10 seconds, creating a contradictory sequence where the door was briefly open but instantly secured without a confirmed exit trigger.

Explanation: Occupancy sensors consistently reported zero presence in all rooms from midnight until 06:42 (when residents woke up), meaning no legitimate resident was inside to perform the manual unlock at 07:39.

Explanation: The late-night auto-lock at 22:06 coincided with total vacancy and window covering changes, suggesting the security system may have been compromised or misconfigured during the earlier incident.

Explanation: No further access logs or motion events occurred after 07:39 until the next morning routine, implying either an intruder gained temporary access or the system malfunctioned due to tampering.

Review CCTV footage between 07:38 and 07:45 to identify who performed the manual unlock.

Inspect the physical front door lock mechanism for signs of tampering or bypass attempts.

Reboot the smart lock controller and reset the 'Auto' lock configuration to ensure it only triggers on verified geofence exits or scheduled times.

Change all relevant credentials and review user access logs for any unauthorized app-based commands.

Lock state transition from Locked(2) to Unlocked(1) via Manual operation at 07:39, immediately followed by Auto lock.

Late-night Auto-lock event (22:06) coinciding with total household vacancy detected by all sensors.

Absence of any activity logs between the late-night auto-lock and the end of the packet, suggesting no verification of entry/exit.

Check camera footage or motion sensor logs between 07:38 and 07:45 to confirm who performed the manual unlock.

Verify the configuration of the 'Auto' lock trigger: Is it based on geofencing exit, schedule, or a specific sensor timeout?

Review access control logs to see if any temporary passcodes or smart home app actions were used around 22:06.

Cross-reference utility usage or appliance status during the 22:00 - 23:00 window to ensure no residents remained undetected.

有人在卫生间正常使用中触发，且短时间内恢复为 false

The system reports 'Auto' unlocks without physical intrusion; raw logs confirm the door contact sensor falsely triggered (flipped to False then True) while no manual unlock followed, indicating a stuck or glitching sensor rather than unauthorized entry.

Explanation: Raw logs at 07:28 show the front door contact state changed from True (closed) to False (open) and back to True within 6 seconds, with no subsequent 'Manual' unlock event recorded.

Explanation: Despite the contact sensor briefly reporting 'False' (suggesting the door was opened), the lock automatically re-locked immediately after, and there is no evidence of forced entry or lingering occupancy during this window.

Explanation: The same pattern occurs at 22:08 where the contact sensor momentarily flips to False before the auto-unlock, but the house remains empty (occupancy sensors are 0) until residents return later in the evening, ruling out intrusion.

[2026-06-25T07:28:21] front_door_contact | BooleanState.StateValue = True

Inspect the front door contact sensor wiring and alignment for debris or misalignment causing false triggers.

Reset the smart lock firmware to clear any potential logic glitches associated with the sensor input.

Check the raw signal strength and proximity logs for the front door contact sensor around 07:28 and 22:08 to see if the door was physically opened.

Verify if any other Auto-triggered events (lights, thermostats) occurred simultaneously with the Auto-unlocks.

Cross-reference the 'Auto' unlock timestamps with the timestamp of the last known manual interaction or user presence log.

The smoke alarm triggered a fire alert during a scheduled self-test cycle that was successfully completed and cleared by the system.

Explanation: The log shows 'TestInProgress=True' at 21:02:00 immediately preceding the 'COState=1' event, indicating an automated test sequence.

Explanation: The 'COState' flag reverted to 0 and 'SelfTestComplete()' was logged within 30 seconds, confirming the system handled the event as a routine diagnostic rather than a persistent real-world emergency.

Explanation: Supporting sensors (temperature, occupancy) show no anomalies during this window; temperatures are consistent with normal evening cooling trends, and no other kitchen sensors reported faults.

Log the event as a completed maintenance routine.

No further investigation or user notification is required.

Verify if the 'SelfTestComplete' event at 21:02:30 actually cleared the 'COState=1' flag or if it was a separate test cycle that coincidentally occurred after the alarm.

Review the command history for the smoke alarm between 21:02:00 and 21:02:30 to determine who/what initiated the 'TestInProgress=True' flag.

FG-03-FP: 烟雾报警器自检触发CO检测

No security threat detected; all events correspond to normal household routines including morning wake-up sequences, scheduled smoke alarm testing, and automated evening departure protocols.

Explanation: Occupancy logs show consistent '0' readings during the night (00:00-06:27), confirming no intruders were present prior to the 22:05 event.

Explanation: The 22:05:18 bedroom window opening was immediately followed by lights turning on at 22:05:15 and an auto-unlock at 22:05:29, indicating a standard 'Goodnight/Departure' automation sequence rather than a breach.

Explanation: The kitchen CO alarm activation at 10:43 is explicitly linked to a 'SelfTestInProgress' flag starting exactly one minute prior, ruling out a gas leak or malfunction.

[2026-06-05T22:05:15] bedroom_light | OnOff.OnOff = True

Continue monitoring routine operations.
No immediate action required.

Occupancy sensors for all rooms show '0' at 00:00 and 00:30, which likely indicates a system reset or absence of motion, not necessarily continuous occupancy during the 22:05 event.

The 'Auto' source often corresponds to smart-home routines triggered by time or other sensor states (like window closing), rather than forced entry.

Timestamps surrounding the 'living_room' and 'kitchen' activity spikes to correlate with human presence vs. appliance operation.

The specific logic triggering the 'Auto' unlock at 22:05:29 (e.g., was it linked to the bedroom window closing at 22:05:18?).

Duration and context of the Kitchen Smoke Alarm activation (COState=1) to confirm if it was solely part of the test sequence initiated at 10:43:00.

Historical data for the Front Door Lock to determine if 'Auto' unlocks are consistent with evening departure routines or irregular occurrences.

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 door events represent a normal routine of leaving and returning home, supported by clear occupancy changes prior to the first lock operation.

Explanation: Occupancy sensors confirmed residents were present in the bedroom and bathroom between 06:33 and 07:15, refuting the hypothesis of an empty house during the morning event.

Explanation: The sequence at 07:15 (Manual Unlock -> Door Opens/Closes -> Auto Lock) perfectly matches the behavior of a resident opening the front door from the inside to leave, rather than an external breach.

Explanation: The evening event at 18:16 follows the same logical pattern of manual entry followed by automatic locking upon re-entry.

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

The front door lock exhibits conflicting operational states (Manual Lock followed immediately by Auto Unlock) while the house is confirmed empty, suggesting a malfunction or logic error rather than routine user behavior.

Explanation: Occupancy sensors confirm the house was empty from 00:00 to 06:19, and residents only re-entered at 20:44, making the 07:39 activity suspicious if not automated.

Explanation: At 07:39, a 'Manual' lock operation occurred while the door contact was open, but this was immediately followed by an 'Auto' unlock command within 8 seconds, resulting in an unlocked state despite the manual input.

Explanation: This rapid reversal of lock status without corresponding motion detection inside the home contradicts standard security routines where a resident would leave and lock the door, or enter and find it locked.

All occupancy sensors reported 0 between 00:00 and 06:19

Inspect the smart lock battery and mechanical linkage for physical obstructions or failure.

Check device logs for any firmware glitches or unauthorized remote commands during the 07:39 timeframe.

Temporarily disable automatic unlocking features until the issue is resolved.

[2026-06-15T22:14:35] front_door_lock | DoorLock.LockState = 1

Timestamped logs for all room occupancy sensors between 07:38 and 07:40 to confirm if anyone was moving in the kitchen or living room when the door was manually locked then unlocked.

Specific definition of 'UserIndex=3' and 'UserIndex=5' in the device configuration to determine if they map to known household members.

Raw BLE/Wi-Fi signal strength or MAC address associated with the 'Auto' source at 07:39:25 and 22:14:26 to distinguish between internal automation scripts and potential smart-lock hacking attempts.

History of window coverings state prior to 06:19:16 to see if the blinds were manually opened/closed by a person or automated.

开窗前住户先在同一房间活动并开灯，是主动行为

No security threat detected; the door lock event was an automated routine triggered by a contact sensor change during the owner's return, and the window state change was part of a manual thermostat adjustment sequence.

Explanation: The front door lock event (23:03:27) occurred immediately after the contact sensor transitioned to True (23:03:26), indicating the resident arrived at the door and triggered the 'Auto' locking protocol upon entering, rather than forced entry.

Explanation: Occupancy logs confirm the house was empty from midnight until 23:04:00 when occupancy returned to 1, consistent with a single resident returning home to secure the premises.

Explanation: The living room window covering closed at 10:09:24 immediately following a thermostat mode change (10:09:17), suggesting a coordinated manual or script-based energy-saving action rather than an intrusion attempt.

FG-03-FP: 烟雾报警器自检触发CO检测

The event is a confirmed routine smoke alarm self-test with no signs of intrusion or fire risk.

Explanation: Raw logs show the smoke alarm entered 'TestInProgress' state at 18:40:00 and completed 'SelfTestComplete()' at 18:40:30, indicating a scheduled maintenance cycle.

Explanation: The COState changed to 1 immediately after the test started and returned to 0 upon completion, consistent with a simulated trigger rather than actual smoke detection.

Explanation: No occupancy sensors were triggered during the test window (18:40:00-18:40:30), and all other sensor readings between 00:00 and 05:00 reflect normal environmental conditions without anomalies.

Acknowledge the log entry as a routine system check.

INS-05-FP: 住户换了新手机/手表解锁

虽然用了不常用的RFID方式解锁，但进门后最终开灯、正常活动，行为模式与住户一致

The event is a legitimate system routine where the front door auto-locked after closing, consistent with a scheduled or geofence trigger.

Explanation: Occupancy sensors confirm the house was empty from 19:03 until 22:48, ruling out an intruder present during the gap.

Explanation: The log shows the door contact opening at 22:45:18 and immediately locking at 22:45:19 via 'OperationSource=Auto', indicating a standard closure lock rather than forced entry.

Explanation: No unauthorized unlock events or motion detection occurred in the entrance area between the last known exit (19:03) and the auto-lock (22:45).

[2026-06-27T22:45:18] front_door_contact | BooleanState.StateValue = True

Evidence indicates a forced entry attempt at the front door followed by successful manual override using an authorized user ID, suggesting either an intruder with access credentials or an insider threat.

Explanation: At 17:20:00, a LockOperationError occurred on the front door with an unknown OperationSource (3), indicating a mechanical failure or forced manipulation attempt.

Explanation: Exactly 20 seconds later (17:20:20), a successful unlock operation occurred from the same source but identified as UserIndex=1 (likely a resident), which implies the lock was physically bypassed or the handle was turned to override the error state.

Explanation: The sequence of Error -> Immediate Manual Override within the same minute, combined with the subsequent opening of the door contact, strongly points to a security breach rather than a normal routine.

Explanation: Normal locking events in the raw log show standard patterns (Manual then Auto re-lock) without preceding errors, highlighting the abnormality of the 17:20 incident.

[2026-06-12T17:20:22] front_door_contact | StateValue = False

Immediately verify the physical status of the front door and change all external door locks.

Review entrance camera footage between 17:19:00 and 17:21:00 to identify if anyone was present during the error/override sequence.

Investigate why 'UserIndex=1' was able to successfully operate the lock immediately after a reported error; check for credential compromise or physical tampering tools.

Notify the homeowner and local authorities if no explanation is provided by the resident regarding the incident.

No security threat detected; the lock error was resolved immediately by an authorized user with no signs of intrusion or forced entry.

Explanation: Occupancy logs show the home was empty during the night and early morning, confirming the house was unoccupied before the incident at 14:17.

Explanation: At 14:16:23, occupancy detected at the entrance preceded the error at 14:17:00, indicating a person (likely the resident) was already present at the door rather than an intruder approaching from outside.

Explanation: The 'OperationError' was followed 20 seconds later by a successful manual unlock (Source=3, UserIndex=1) and subsequent normal locking patterns (manual lock at 18:17, auto-lock at 22:06), proving full control was regained without forced re-entry.

[2026-06-09T14:16:23] entrance_occupancy | OccupancySensing.Occupancy = 1

Verify if UserIndex=1 corresponds to a known household member in the system configuration.

Optional: Check lock firmware for known issue regarding OperationError=1 to prevent recurrence if it indicates a specific mechanical fault.

Check the specific error code 'OperationError=1' definition for the lock model to determine if it indicates low battery, mechanical jam, or remote command rejection.

Verify the identity of 'UserIndex=1' associated with the 14:17:20 unlock to confirm it matches a known household member.

Review motion sensor logs between 14:17:00 and 14:17:20 to see if anyone approached the door prior to the unlock attempt.

Check if the 'OperationSource=3' corresponds to a remote app command or a third-party integration that might be failing.

第二人通过合法凭证解锁（不同UserIndex），且有合理时间间隔

Multiple front door lock operations occurred while all room occupancy sensors consistently reported zero occupants for over 11 hours, indicating unauthorized access or entry by an unknown party.

Explanation: Occupancy sensors across all rooms (living_room, bedrooms, bathroom, entrance) consistently reported '0' from 00:00 to at least 11:30, confirming the home was empty during the event window.

Explanation: Two distinct lock operations were recorded at 11:22 and 11:27 with UserIndex values of 1 and 2, which differ from typical system maintenance IDs and suggest human interaction rather than automated scripts.

Explanation: The sequence implies a person entered the property (potentially using a stolen key, compromised code, or physical force), moved through the house without triggering occupancy alarms (suggesting stealthy movement or sensor failure, but the lock events are the primary anomaly), and subsequently locked the door.

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

Change all smart locks, door codes, and associated mobile app credentials immediately.

Review historical camera footage if available to identify the intruder's appearance or vehicle.

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 auto-lock event was a normal system function triggered by the door contact sensor closing after the occupant exited; the subsequent occupancy reading of '1' confirms no one is trapped inside.

Explanation: At 23:12:37, the front door contact sensor registered as True (closed), indicating the door was shut.

Explanation: Immediately at 23:12:38, the lock executed an 'Auto' operation, which is the expected behavior when the system detects the door has closed and no motion is detected inside.

Explanation: Critically, at 23:13:00 (just over 40 seconds after locking), the living room occupancy sensor updated to '1', proving that an occupant was present in the house at the time of locking and subsequently entered or remained inside safely, contradicting the theory of an empty house being locked prematurely.

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

The data indicates a house with all residents absent and heating systems running normally; there is no evidence of intrusion or sensor failure.

Explanation: Occupancy sensors consistently report zero across all zones (kitchen, living room, bedrooms, bathroom, entrance) at regular intervals, which aligns perfectly with the hypothesis that the household is unoccupied.

Explanation: Temperature readings show a logical, gradual increase over time (from ~22°C to ~24.5°C), indicating active HVAC operation in an empty home rather than a malfunction or fire risk.

Explanation: The perfect synchronization of '0' readings across five different rooms is statistically probable for a vacant house where no human movement exists to trigger motion sensors, refuting the sensor failure hypothesis.

All occupancy logs explicitly state 'OccupancySensing.Occupancy = 0' from 00:00 to 05:30.

Temperature values rise steadily and logically (e.g., 2269 -> 2310 -> 2357 -> 2413 -> 2454), confirming system functionality.

Confirm via smart lock logs if doors were locked upon departure.

Monitor temperature trends to ensure they remain within safe comfort ranges while the house is empty.

[2026-06-21T00:30:00] second_bedroom_occupancy | OccupancySensing.Occupancy = 0

Check raw telemetry for 'battery_low', 'communication_timeout', or 'device_offline' flags on all occupancy sensors.

Review the definition of 'salient_event_count' vs 'focus_event_count': Do these events correspond to temperature fluctuations, door contact changes, or just generic motion triggers? If they are door contacts, check if doors are being opened/closed by wind or pets.

Verify the timestamp accuracy and clock skew across all devices to ensure simultaneous readings aren't due to time desynchronization issues.

Cross-reference with camera feeds (if available) or smart lock logs to see if anyone actually entered/left the home around 00:00.
