洗碗机运行期间厨房漏水传感器触发 两个事件的时间关联性

停止洗碗机运行，通知住户检查

Evidence confirms an unauthorized entry sequence where a door was manually unlocked and entered at 07:18:11, followed immediately by an automatic re-lock at 07:18:18 without a corresponding manual lock event, indicating the person inside likely triggered the auto-lock upon exiting.

Explanation: Occupancy sensor in 'entrance' changed to 1 at 07:18:08, preceding the manual unlock.

Explanation: Door contact sensor confirmed the door opened (False) at 07:18:13 and closed (True) at 07:18:17.

Explanation: The lock transitioned from Manual Unlock (07:18:11) directly to Auto Lock (07:18:18), bypassing the expected user action of manually locking the door after entry, which is characteristic of tailgating or automated exit-triggered locking.

Explanation: This pattern contrasts with the normal evening routine at 22:15 where the door was locked automatically after being left open with no prior manual unlock/occupancy cycle shown in that specific window, suggesting the morning event involved active manipulation.

Verify the identity of any family members scheduled to be home during this time via access logs or user confirmation.

Review security camera footage if available for the front door between 07:18:00 and 07:19:00 to visually confirm if multiple people were present.

Adjust smart lock settings to require a manual lock confirmation or disable auto-locking upon exit until verified as safe.

Verify if any other motion sensors (entrance, living_room, hallway) triggered within this 7-second window.

Review the 'OperationSource' logic for the Auto-lock at 07:18:18; determine if it is a system default or triggered by a specific sensor state.

Cross-reference timestamps with user schedules or known family members' departure times.

The sequence of events represents a standard resident departure (lock then exit) followed immediately by an automated sensor-triggered unlock as the door swung open, with no evidence of forced entry or unauthorized presence.

Explanation: Occupancy sensors in the entrance and living room were active just prior to the lock event, confirming the resident was present and exiting.

Explanation: The 'Manual Lock' at 07:20:21 was immediately followed by the contact sensor going False (open) at 07:20:23, indicating the door was opened from the inside shortly after locking.

Explanation: The subsequent 'Auto Unlock' at 07:20:31 coincides exactly with the door being open, which is consistent with a normal smart-lock feature that unlocks when the door is detected as open, rather than a security breach.

[2026-06-18T07:20:23] front_door_contact | BooleanState.StateValue = False

Continue monitoring; no immediate action required.

Optional: Verify if the specific smart-lock model has a setting to delay auto-unlock if triggered immediately after manual locking for better user experience, but this is not a security issue.

[2026-06-18T22:05:38] front_door_lock | DoorLock.LockState = 1

Check if there were concurrent motion sensor triggers in the entrance hallway or living room between 07:20:21 and 07:20:31 to confirm if someone entered before the auto-unlock.

Verify the specific firmware version and known bugs for the door lock device regarding 'Auto' unlock triggering shortly after manual locking.

Inspect the contact sensor log for the front door to see if the door remained open longer than expected between the two events.

Review the full raw log around 07:20 to check for any other simultaneous anomalies (e.g., smoke detectors, glass break sensors).

A forced entry attempt was detected late at night while the house was unoccupied, characterized by repeated lock failure errors followed by an alarm.

Explanation: Occupancy sensors confirmed all rooms (living room, bedrooms, entrance) were empty between 00:00 and 23:13, indicating no residents were present to operate the door manually.

Explanation: At 23:13:03, motion/occupancy was detected in the entrance area immediately preceding the security events.

Explanation: The log shows a rapid sequence of four 'LockOperationError' events from Source 3 within 40 seconds, culminating in a 'DoorLockAlarm', which is inconsistent with normal user behavior or mechanical failure alone given the prior successful manual locks.

Explanation: The combination of unauthorized presence detection and repeated automated locking failures strongly indicates an intruder attempting to force the door open.

The event at 07:32 AM is a normal resident arrival and departure sequence confirmed by occupancy sensors and physical door contact logs.

Explanation: Occupancy sensors detected entry (state=1) at 07:32:15, preceding the manual lock command, confirming human presence.

Explanation: Raw logs show the door opened briefly (contact=False for 6 seconds) immediately after locking, consistent with a resident entering and closing the door, rather than an intrusion attempt where the door would remain open or be forced.

Explanation: No motion events were recorded inside the house between midnight and 07:32, supporting the hypothesis that the house was empty until this specific arrival.

温度异常上升但无合理热源（空调关闭/制冷模式，灶具关闭） 上升速度超过正常烹饪或日照导致的范围

火灾风险警报，建议住户检查该区域电器

A confirmed fire risk exists due to a sustained and unexplained temperature rise in the kitchen while the residence was unoccupied, culminating in a smoke alarm trigger.

Explanation: The raw logs show the kitchen temperature rising steadily from ~22°C at midnight to ~250°C (value 2502) by 13:20, which is physically impossible for ambient conditions or typical appliance residue.

Explanation: This continuous thermal anomaly occurred over 13 hours while occupancy sensors confirmed the house was empty, ruling out normal cooking activities.

Explanation: The temperature spike directly correlates with the smoke alarm activation at 13:23, indicating an active combustion event or severe malfunction rather than a false positive.

[2026-06-14T13:20:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2502

Immediately dispatch emergency services/fire department to the location.

Do not attempt manual verification until authorities arrive.

[2026-06-14T00:30:00] master_bedroom_occupancy | OccupancySensing.Occupancy = 0

Raw readings from kitchen_temperature_sensor before, during, and after 13:23 to check for thermal anomalies.

Kitchen_cook_surface and dishwasher status logs to rule out appliance malfunction causing heat/smoke.

The event log depicts a standard evening routine where the resident locked the door remotely using an authorized device (UserIndex=1), followed by normal overnight occupancy patterns and morning/evening departures.

Explanation: The lock operation at 01:24 explicitly includes 'UserIndex=1', which identifies the actor as a registered household member, directly refuting unauthorized entry hypotheses.

Explanation: Operational context confirms legitimacy: Occupancy sensors show the resident entering ('Occupancy=1') immediately after the remote lock command and settling in, consistent with returning home late at night.

Explanation: Subsequent events follow a logical pattern: all-night absence (occupancy=0), morning departure (07:40), and evening return (18:25) matching typical daily schedules.

Explanation: Temperature fluctuations are gradual and within expected environmental ranges, showing no signs of sensor malfunction or fire risk.

Log entry: 'Event: LockOperation(..., UserIndex=1)' proves authorized user action.

Sequence: 'Occupancy=1' at 01:24:05 follows the remote lock, confirming the user was physically present inside the secured perimeter.

No action required; continue monitoring standard operational logs.

Optional: Verify firmware documentation to confirm 'OperationSource=8' maps to the primary mobile app for future reference, though current evidence is sufficient.

[2026-06-02T18:25:00] front_door_lock | DoorLock.LockState = 2

Check the definition of OperationSource=8 in the device firmware documentation to confirm if it corresponds to the primary mobile app used by UserIndex=1.

Verify the sequence of events immediately following the 01:24:00 lock operation to ensure no subsequent forced re-entry attempts occurred.

Cross-reference the 07:40 manual lock/unlock cycle with calendar data to confirm these times align with typical resident wake-up/sleep schedules.

No security threat detected; observed events are consistent with normal household operations and device battery warnings.

Explanation: Occupancy sensors confirm the home was empty from 00:00 to 07:12, with residents returning at 07:14 and leaving at 16:02/17:46, matching a standard daily pattern.

Explanation: The 'Auto' lock operation at 07:12:25 occurred immediately after manual locking and door contact restoration, indicating a scheduled or firmware auto-relock feature rather than an intrusion attempt.

Explanation: The kitchen temperature spike to 3172 (likely scaled units for ~89°C) and subsequent smoke alarm alert show SmokeState=0, confirming no actual fire or carbon monoxide leak occurred.

[2026-06-09T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

Verify the battery voltage history for the kitchen_smoke_alarm to confirm if the low battery warning led to any false smoke readings or communication timeouts.

Cross-reference the 'room_activity' counts with motion sensor logs to ensure the high count in 'entrance' (24) doesn't hide multiple rapid re-entry attempts within short windows.

Check if the Kitchen Window Sensor triggered any state changes alongside the smoke alarm alerts.

中等可信度警报，建议住户确认是否本人操作

An intruder likely entered the empty home at night by manipulating the master bedroom window coverings to gain access or visibility, followed immediately by a door state change consistent with forced entry or an automated response to a breach.

Explanation: Occupancy sensors confirmed all rooms were empty ('0') from 00:00 onwards, ruling out authorized residents being present.

Explanation: At 22:13:27, while the house was empty, the master bedroom window covering position changed to 100% (open), indicating manual manipulation rather than standard automation.

Explanation: Exactly 9 seconds later at 22:13:36, the front door lock state changed to '1' (unlocked) via an 'Auto' source, which correlates temporally with the window event and contradicts normal user behavior patterns for an empty house.

Explanation: The sequence of opening a window in a private room immediately before a door unlocks in an empty house is statistically improbable for legitimate household activities.

Verify if any motion sensor in the hallway or living room triggered between 22:13:00 and 22:15:00.

Review camera feeds (if available) for the master bedroom window area around 22:13.

Check the 'UserIndex=8' event at 10:13:00 to confirm if this user identity matches an authorized family member or a known intruder profile.

The event log represents a routine evening departure and morning arrival sequence with no signs of intrusion or system failure.

Explanation: All occupancy sensors consistently reported '0' (empty) throughout the night, contradicting any hypothesis of an intruder hiding in the house.

Explanation: The front door was manually unlocked by a specific user (UserIndex=1) at 04:39 AM, followed immediately by legitimate occupant movement patterns (entrance then living room), ruling out forced entry.

Explanation: The high temperature readings are consistent with normal HVAC operation or passive solar heating during the day, not indicative of fire or gas leaks.

Explanation: The window blind retraction at 10:02 AM occurred after the house was confirmed occupied and is likely part of routine daily habits.

[2026-06-28T04:39:00] UserIndex=1 manual unlock followed by occupancy detection

[2026-06-28T23:06:32] Auto-lock event with no preceding unauthorized access indicators

No action required; system is operating within normal parameters.

[2026-06-28T00:00:00] second_bedroom_occupancy | OccupancySensing.Occupancy = 0

[2026-06-28T00:00:00] bathroom_occupancy | OccupancySensing.Occupancy = 0

The discrepancy between the high total event count (1572) and the relatively low focus event count suggests either background noise from normal usage or a distributed sensor failure/false positive cascade.

Living room window blind position changed to 0% at 10:02:13; context required to determine if this is part of routine cleaning or an attempt to obscure view/access.

Timestamps and source IDs for all 1572 events to distinguish between legitimate user interactions, automated scripts, and potential sensor glitches.

Door lock state history immediately prior to the 23:06:32 Auto-lock event to ensure the door was actually unlocked before locking.

Motion sensor raw data (PIR signatures or beam breaks) for the living room and entrance to correlate with the '17' entrance activities and '26' living room activities.

Kitchen appliance logs (cook_surface, dishwasher) during the day to explain the '12' kitchen activity events.

警告住户烟雾报警器可能失灵，建议更换电池/设备

Evidence confirms unauthorized tailgating where an intruder entered the house after a resident manually unlocked the door, leaving it open for approximately one minute before it re-locked automatically.

Explanation: Occupancy sensors detected a person at the entrance (07:20:14 and 18:15:24) immediately preceding manual unlock events, while all internal rooms remained empty.

Explanation: The front door contact sensor showed the door was open (StateValue=False) for roughly 9 minutes in the first instance and 3.5 minutes in the second, significantly longer than normal entry duration.

Explanation: No subsequent motion was detected inside the house until 22:16:08, indicating the intruder bypassed or avoided interior detection, likely exiting unseen or remaining hidden.

洗碗机运行期间厨房漏水传感器触发 两个事件的时间关联性

停止洗碗机运行，通知住户检查

Evidence indicates an unauthorized entry at 07:31 while the house was confirmed empty (occupancy=0), followed by a lack of normal residential activity until 16:13.

Explanation: Occupancy sensors registered zero presence in all living and sleeping areas from midnight until 06:48, yet the front door was manually unlocked at 07:31:21.

Explanation: The sequence shows manual unlocking (07:31) -> auto locking (07:30) without any subsequent motion or occupancy events in the interior, suggesting the intruder entered and exited immediately or the system failed to detect them inside.

Explanation: Normal household activity did not resume until 16:13 (Master Bedroom occupancy), creating a large window of unaccounted time during which the home was theoretically occupied but sensors showed otherwise.

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

Review entrance camera footage specifically between 07:30:00 and 07:35:00 to identify who unlocked the door.

Check if the 'Auto' lock operation at 07:31:30 was triggered by a smart device app (resident leaving quickly) or a sensor glitch that falsely reported occupancy.

Inspect security logs for the period 07:31 to 16:13 to see if other doors/windows were accessed.

[2026-06-04T07:31:30] front_door_lock | DoorLock.LockState = 1

Morning events (07:31) show Manual Unlock -> Auto Lock. If residents were present, they would likely not leave the door unlocked for long without triggering other motion sensors, yet occupancy is 0 at midnight. This implies the door was manipulated when no one was expected inside.

Front door manually unlocked at 07:31:21 with zero occupancy detected in living/sleeping areas until 00:00 (implying the house was empty when entered).

Front door manually unlocked AGAIN at 22:17:31 after being locked since 18:02:00, suggesting potential break-in and exit, or confused locking logic due to intruder presence.

Correlation between high entrance activity and low occupancy elsewhere suggests people moving through the door without settling into rooms.

Check camera footage from Entrance and Living Room around 07:31:21 and 22:17:31 to identify who operated the lock.

Verify if any motion sensor triggered in Living Room or Master Bedroom *after* the 07:31:21 unlock but *before* the 00:00:00 occupancy reset to confirm if anyone entered briefly.

Check the source IP/MAC address of the 'Auto' lock operation at 07:31:30 to determine if it was triggered by a smart device (phone) or a sensor glitch.

Review window covering logs for Kids Room (06:46:08 open) vs others closed/open status to see if blinds were opened before the suspected intrusion.

The sequence at 07:22 represents a normal user routine of unlocking the front door to enter the home and immediately triggering an automated 'Auto Lock' feature upon entry or via a smart home routine, confirmed by subsequent occupancy data.

Explanation: Occupancy sensors show zero activity from 00:00 to 07:22:28, indicating no unauthorized presence before the event.

Explanation: At 07:22:36, the manual unlock is immediately followed by an 'Auto' lock operation and state change to Locked (1), which is consistent with a resident entering and activating a secure-entry routine.

Explanation: Crucially, the entrance occupancy sensor registers presence ('1') at 07:22:39, confirming that a person was legitimately inside the premises after the door was locked.

[2026-06-19T07:22:39] entrance_occupancy | OccupancySensing.Occupancy = 1

Continue monitoring; no immediate action required as the behavior aligns with legitimate entry patterns.

Verify if the household has an active 'Auto-Lock on Entry' or similar smart home routine configured for the front door.

[2026-06-19T22:35:27] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Occupancy sensors show 0 at 00:00, consistent with residents sleeping or away overnight.

The specific lock state change pattern at 07:22 (Unlock->Auto Lock) lacks the explicit 'Manual Lock' confirmation often seen in standard logs if performed manually by a user, raising ambiguity about authorization.

Potential tampering with child safety features or unauthorized access to children's area indicated by early morning window status changes.

[2026-06-19T06:36:12] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 0 (Fully Closed)

This occurs ~45 minutes before the potential door incident, possibly indicating someone ensuring windows are closed before entering or leaving.

Window coverings are typically closed for privacy/safety anyway; less definitive as an anomaly compared to the door lock issue.

Rapid sequence at 07:22:36-07:22:39: Front door unlocked manually, then locked automatically (no manual lock log).

Door lock state changed to '2' (Unlocked) then '1' (Locked) within 3 seconds.

High entrance activity count (19) combined with the ambiguous lock operation source.

Check the authentication method for the Manual LockOperation at 07:22:36 (biometric, PIN, physical key?).

Verify if there was any door contact sensor trigger (open/close duration) immediately preceding the 07:22:36 unlock.

Cross-reference user mobile app usage logs around 07:22 AM to see if the user initiated a 'Leave Home' or 'Arm System' routine that triggers auto-locking.

Check for any forced entry indicators on the contact sensor log (rapid open/close cycles).

Simultaneous zero occupancy readings across all zones combined with rapidly rising temperatures indicate a sensor system failure rather than a human evacuation or fire emergency.

Explanation: All occupancy sensors dropped to '0' simultaneously at exactly 00:00 and remained static for hours, which is characteristic of a system reset or sensor logic error, not natural human movement patterns.

Explanation: Temperature data shows a steady increase (2272°C -> 2399°C in the kitchen), suggesting either a malfunctioning temperature sensor reporting invalid high values or an external environmental factor, but critically, no smoke/heat alarm was triggered to cause a panic evacuation.

Explanation: The front door lock event by UserIndex=3 at 17:04 followed by the contact sensor closing confirms the house was physically secured normally; the anomaly lies solely in the state reporting of the occupancy and temperature systems after midnight.

[2026-06-06T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0 (and identical for all other rooms)

[2026-06-06T00:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2272

[2026-06-06T04:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2399

Immediately verify physical presence of residents via video feed or direct phone call.

Dispatch technical support to check and recalibrate occupancy and temperature sensors.

Do not assume fire based on temperature readings until verified, as the lack of alarm activation suggests sensor drift/failure.

No security threat detected; logs indicate standard daily routines with authorized lock operations and consistent occupancy patterns.

Explanation: All rooms reported '0' occupancy at midnight (00:00) through early morning, confirming the house was empty as expected.

Explanation: The unusual 'UserIndex=1' at 09:40 is corroborated by immediate contact sensor state changes (False then True), proving an authorized person opened and closed the door rather than a forced entry or tailgating attempt.

Explanation: Nighttime sequences show intentional window closing (position 100%) following manual locks and no motion sensors triggered in hallways or bedrooms prior to these actions.

[2026-06-10T07:27:24] front_door_lock | DoorLock.LockState = 2

Window covering movements happen after lock engagements, suggesting intentional closing rather than forced entry resistance.

[2026-06-10T22:31:20] front_door_lock | DoorLock.LockState = 1

Timestamps of 'contact_sensor' readings for entrance door and all room windows to ensure no breach occurred between the last reported lock state change and the next occupancy report.

Identity mapping for 'UserIndex=1' and 'OperationSource=8' to confirm they belong to authorized household members.

Raw contact sensor logs for the front door around 07:27 and 22:31 to distinguish between 'lock from inside', 'unlock from outside', or 'forceful opening'.

Motion sensor logs in the hallway and entrance area immediately preceding any window closing events to rule out stealthy movement.

触发安全警报，临时禁用 Keypad 输入，通知住户

Repeated forced lock attempts on the front door at night triggered an alarm, indicating a likely break-in attempt.

Explanation: The raw log shows a cluster of 'LockOperationError' events between 22:59:00 and 22:59:40 with a consistent unknown source (Source=3), followed immediately by a 'DoorLockAlarm'.

Explanation: This pattern of repeated failures preceding an alarm is characteristic of physical jamming or brute-force entry attempts rather than simple user error.

Explanation: Occupancy sensors confirmed the house was empty during this specific window, ruling out authorized resident operation.
