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

The event sequence represents a resident leaving the master bedroom and manually securing the front door shortly after an automated unlock trigger, consistent with normal household behavior.

Explanation: Occupancy logs confirm residents were present in the master bedroom at 22:49:13 and 22:49:26, ruling out an unoccupied home scenario where an intruder could operate locks.

Explanation: The 'Auto' unlock at 22:49:23 was immediately followed by a 'Manual Lock' operation at 22:49:23 (5 seconds later), indicating an authorized user actively secured the door rather than a breach or failure to lock.

Explanation: The contact sensor state transition (True -> False -> True) between 22:49:22 and 22:49:23 confirms the door was physically opened and then closed/locked by someone inside.

master_bedroom_occupancy = 1 at 22:49:13 and 22:49:26

If the door was locked at 17:56, who unlocked it at 22:49? The log says 'OperationSource=Auto'. Smart locks often auto-unlock when approaching or via geofence. If residents were gone (occupancy 0 since 00:00 previous night? No, occupancy logs are daily snapshots). The occupancy logs at 00:00 show empty rooms. This suggests everyone is asleep/away. An 'Auto' unlock at 22:49 is suspicious if no one is home, but smart locks can be programmed. Let's re-evaluate the sequence: Lock(Man) @17:56 -> Unlocked(State=2->1) @22:49:18 -> Lock(Man) @22:49:23. This implies a very short window where the door was unlocked. If the source of the first unlock was 'Auto', it might be a false trigger or a scheduled event. But the second lock is 'Manual'. This contradicts the idea of a break-in where the thief leaves the door open or fails to close it; here, the door was actively re-locked manually within seconds of being unlocked.",

The system registered a smoke alarm due to a sensor reading of ~250°C (likely data drift or calibration error) while the house was empty and locked, followed by normal resident activity.

Explanation: Raw logs show kitchen temperatures rising to 235-251 units (likely °C or scaled index) between 02:30 and 07:15, which is physically impossible for a standard residential environment without an active fire or severe equipment failure, indicating sensor drift.

Explanation: Occupancy sensors consistently reported '0' (empty) during these high-temperature readings, and the front door contact remained 'True' (closed/locked) until residents arrived at 06:33, ruling out an intruder present before arrival.

Explanation: Residents entered normally at 06:33, opened windows, and then triggered the smoke alarm at 07:33. The subsequent sequence shows them securing the home naturally (closing blinds, locking doors via Auto protocol), confirming no forced entry occurred.

Immediately replace or recalibrate the kitchen temperature/smoke sensor.

High room activity count (20 in entrance) combined with low occupancy sensor readings suggests someone moving through the house without triggering motion sensors or being detected as 'present' in main rooms.

Timestamps and IP addresses/MAC addresses for the 'front_door_lock' unlock event at 22:14:25 to determine if it originated from inside or outside.

Raw sensor readings from the kitchen around 07:33:00 to distinguish between heat/smoke particles vs. actual fire conditions.

Motion sensor logs for the hallway/entrance area between 07:33 and 22:14 to see if movement occurred despite 'Occupancy=0' flags in main rooms.

Access control logs to verify if the manual lock operation at 22:14 corresponds to a keycard swipe, code entry, or physical manipulation.

No security threat detected; observed events are consistent with normal household automation schedules and the return of occupants.

Explanation: The 'Auto' unlock at 07:07:13 occurred immediately after a door contact change (False to True) indicating someone opened the door, followed by occupancy detection in the entrance at 08:17, confirming a legitimate entry/exit cycle rather than an unattended breach.

Explanation: The bedroom window toggling events correlate perfectly with specific occupancy changes: it opened when the bathroom was occupied (likely someone moving through or checking the room) and closed when the bedroom occupant returned at 14:07, indicating user-controlled automation based on presence.

Explanation: Temperature sensor readings show a gradual rise from ~22°C to ~25°C over the day, which is consistent with normal daytime heating cycles and does not indicate equipment failure or environmental hazards.

[2026-06-14T14:07:00] bedroom_occupancy | OccupancySensing.Occupancy = 1 occurring 4 seconds before the window closing event

Review smart-home automation rules to ensure window coverings close automatically upon detecting occupancy to improve privacy.

Verify firmware versions for all connected devices to confirm no known vulnerabilities exist, though current behavior appears benign.

Front door lock cycle (Manual Lock -> Auto Unlock -> Manual Lock) occurring during a time when the house shows 0 occupancy in all zones.

Bedroom window covering toggling (Closed -> Open -> Closed) multiple times without any detected motion or occupancy in the bedroom.

Check raw video feeds from the entrance and bedroom for visual confirmation of presence or intrusion attempts during the timestamps 07:07:06 and 14:07:06.

Verify the firmware version and configuration of the front door lock to determine if 'Auto' unlock is a legitimate scheduled routine or a vulnerability exploitation.

Cross-reference the timestamp of the window opening events with the smart-home assistant logs to see if they were triggered by voice commands or app automation rules.

The event sequence is consistent with a resident waking up early, performing routine door checks/lock verification, and experiencing an unrelated plumbing leak later in the day.

Explanation: Occupancy sensors confirm the house was empty from 00:00 until 06:54, when bedroom occupancy first registered as '1', indicating a resident arrived or woke up at that time.

Explanation: The manual lock/unlock at 06:51 occurred immediately after the resident's arrival (06:54) and before sustained activity; the door contact sensor (False then True) confirms the door was physically opened and closed by someone inside, likely checking the lock rather than an intruder entering.

Explanation: The bathroom leak at 10:42 is temporally disconnected from the morning entry sequence; no suspicious entry patterns exist between 08:34 and 10:42, and subsequent logs show normal resident presence in other rooms.

[2026-06-11T06:54:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-11T06:51:09] front_door_contact | BooleanState.StateValue = False followed by [2026-06-11T06:51:16] ... StateValue = True

Investigate the source of the bathroom water leak detected at 10:42 for repair.

No immediate security threat response required; continue monitoring standard household activities.

Intruder entered via front door (manual unlock) around 08:34, stayed until at least 10:42 when they used the bathroom causing a leak, then exited. The subsequent auto-lock at 10:42 might be sensor-triggered by motion or just system default, but the sequence is suspicious.

Bathroom water leak detected at 10:42:00 (approx 2 hours later)

Occupancy data shows empty house at 00:00 and 00:30, suggesting long absence before this event sequence

No explicit occupancy sensor trigger logged for bathroom at the exact moment of leak (though logs are sampled)

Front door manual lock operation at 08:34:00 followed by no immediate exit signal, then bathroom leak at 10:42:00 suggests prolonged presence inside.

Water leak in bathroom during a time window where the household appeared empty based on initial occupancy checks.

Check raw occupancy sensor timestamps for bathroom specifically between 08:30 and 11:00 to confirm if someone was present.

Verify the 'Auto' source at 06:51:17 and 20:39:07: Was it a smart lock feature or motion-triggered? Check proximity sensors.

Review camera footage (if available) or audio logs from entrance/bathroom around 08:30-11:00.

Check if the resident has a history of waking up at 06:51 and using the bathroom immediately after to establish baseline behavior.

A confirmed fire alarm activation in the kitchen correlates with a significant and sustained temperature spike in that same room, indicating an active fire hazard rather than a sensor malfunction.

Explanation: The kitchen smoke alarm triggered at 17:53:00, immediately coinciding with the presence of occupants in the kitchen.

Explanation: Temperature logs show a steady and rapid rise in the kitchen from ~23°C at 04:30 to ~25°C (2512) by 12:25, suggesting prolonged heat generation consistent with unattended cooking or a smoldering fire.

Explanation: Unlike the door/window events which have plausible explanations for manual operation (residents entering/leaving), the combination of smoke detection and high thermal readings in the kitchen presents a definitive life-safety threat.

kitchen_temp_sensor readings increasing from 2274 at 00:00 to 2512 at 12:25

Immediately dispatch emergency services (Fire Department).

Instruct all household members to evacuate the premises if not already done.

Do not attempt to extinguish the fire personally; focus on evacuation and containment until professionals arrive.

A confirmed bathroom water leak occurred while the home was unoccupied for over 10 hours, posing a significant property damage risk.

Explanation: All occupancy sensors reported '0' (empty) from 00:00:00 until 10:44:00, confirming the house was unattended during the critical event window.

Explanation: The raw log explicitly records a 'bathroom_water_leak' state change to True at 10:42:00, which is the primary anomaly.

Explanation: While door lock cycling and temperature spikes suggest other potential issues (automation glitches or HVAC failure), the active water leak in an empty house is the definitive safety threat requiring immediate action.

[2026-06-11T00:00:00] ... entrance_occupancy | OccupancySensing.Occupancy = 0

Dispatch emergency maintenance or plumbing services immediately to stop the leak.

Inspect the bathroom area for water damage and mold prevention measures once repairs are made.

Check camera footage for entrance between 07:00 and 09:00 to rule out unauthorized entry.

Verify if any smart appliances (e.g., washing machine, dishwasher) were scheduled or malfunctioned prior to 10:42:00.

Inspect the source of the 'Manual' vs 'Auto' lock operation commands at 07:04 to determine if they originated from a mobile app or local sensor trigger.

Cross-reference water flow meter data (if available) to confirm volume of leak vs. typical appliance usage.

No security threat detected; all door/window operations correlate perfectly with resident occupancy and routine daily schedules.

Explanation: Door lock events at 07:05, 08:36, and 20:53 show a clear 'Manual Lock -> Door Opens/Closes -> Auto Unlock' sequence, which is consistent with a resident entering or leaving the home and re-arming the system.

Explanation: Occupancy logs confirm the resident was present in the bedroom immediately before window adjustments (12:40) and in the kitchen/entrance during door interactions, ruling out unauthorized entry.

Explanation: The sequence of lights turning on, blinds moving, and doors locking/unlocking follows a logical morning-to-evening timeline typical of human habitation.

[2026-06-08T07:05:10] front_door_lock | OperationSource=Manual followed by [2026-06-08T07:05:21] OperationSource=Auto

[2026-06-08T12:40:06] bedroom_occupancy = 1 occurring 5 seconds before window adjustment

Continue standard monitoring; no immediate intervention required.

Verify if the 'Auto' unlock source is a scheduled smart-home routine or manual trigger by user for future context clarity.

The specific sequence of 'Manual' lock operation immediately followed by 'Auto' unlock within seconds, combined with rapid window state changes, appears slightly more erratic than standard passive behavior.

[2026-06-08T13:54:05] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 0

[2026-06-08T20:53:27] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Check motion sensor (<occupancy_sensor>) logs for the entrance hallway and bedroom specifically around 07:05 and 13:54 to confirm if movement was detected when doors/windows were operated.

Verify the source of the 'Manual' lock operations (User ID vs. System default) to distinguish between resident action and potential tampering.

Cross-reference audio/video feeds (if available) for the entrance and bedroom during the flagged timestamps.

An intruder entered the home undetected by initial sensors, caused a kitchen fire while the house appeared empty, and exited without triggering an alarm.

Explanation: The raw log reveals a critical sensor failure: occupancy sensors in the kitchen, bedroom, living room, and entrance all reported '0' (empty) between 07:06 and 07:14, despite the door contact sensor showing the door was opened (False at 07:06:07) and later closed.

Explanation: This discrepancy confirms that a person entered and moved through the monitored areas, but the motion/presence sensors failed to detect them, creating a false sense of security regarding occupancy.

Explanation: Following this period of undetected presence, a massive temperature spike occurred in the kitchen (rising from ~238°C to 3500 units, likely Kelvin or scaled error indicating extreme heat), coinciding exactly with the smoke alarm activation at 07:12:00.

Immediately dispatch emergency services to the location for fire investigation and safety check.

Secure the premises and preserve the scene for law enforcement investigation.

Check and replace all battery-powered or wireless occupancy/motion sensors immediately to prevent future blind spots.

Kitchen smoke alarm activation (07:12) occurring shortly after manual door lock engagement (07:06) in a house with zero occupancy readings across all rooms.

Door lock state transition from Locked (2) to Unlocked (1) at 08:40, indicating exit, without any subsequent occupancy detection.

Total absence of motion or presence sensors detecting humans during the critical timeframe (07:00 - 09:00).

Raw logs for 'kitchen_cook_surface' (cooktop status) around 07:12 to check for ignition events.

Camera footage or detailed motion sensor raw data points between 07:00 and 09:00 to definitively rule out human presence.

The event log shows a resident waking up and performing normal morning routines, including locking the front door manually, which is consistent with expected behavior.

Explanation: Occupancy sensors confirm the resident was present in the living room (01:07) and kitchen (07:08) shortly after the timestamps in question, ruling out an intruder acting alone while the house was empty.

Explanation: The sequence at 07:07 shows a manual lock engagement followed immediately by a contact sensor change (door opened) and then an auto-lock, which matches the pattern of a resident exiting the house rather than an unauthorized entry attempt.

Explanation: Subsequent logs show standard daytime activities: turning on bedroom lights (05:21), opening/closing windows based on occupancy and time (12:26, 14:04), and evening routines, all indicating a single authorized user managing the smart home.

SmokeCoAlarm 的 COState 变为 Warning 或 Critical

CO 报警是严重安全事件，不同于烟雾报警

紧急通知所有住户撤离，开窗通风，联系燃气公司

A carbon monoxide alarm triggered due to rising kitchen temperatures while the home was unoccupied, followed by normal morning activities.

Explanation: The raw logs show a steady rise in kitchen temperature (from ~226°C to ~242°C) leading up to the CO alarm at 03:24, indicating a thermal event rather than an intrusion attempt.

Explanation: Occupancy sensors confirm the house was empty throughout the night, making unauthorized entry highly unlikely and supporting the theory of an unattended cooking hazard or appliance failure.

Explanation: Subsequent events (window closing, door locking/unlocking patterns) align with normal resident behavior after clearing a minor safety incident, with no evidence of forced entry or tailgating.

[2026-06-04T00:00:00] ... [2026-06-04T04:30:00] OccupancySensing.Occupancy = 0 for all rooms during the incident window

Inspect kitchen appliances and ventilation systems for faults causing overheating.

Verify battery levels and calibration of the smoke/CO detector.

The coincidence of the smoke alarm immediately preceding an unlocked front door state (if temporal proximity implies causality) is suspicious for a lone elder.

Smoke alarms typically trigger full evacuation protocols; if the resident remained inside to adjust windows/curtains while the alarm was active (or just after), this contradicts standard safety behavior unless the threat was minor and quickly resolved.

立即提醒住户关闭灶具，如无法联系则自动关闭（如支持远程关闭）

Kitchen smoke alarm triggered at 20:35 despite normal temperature readings and no occupant presence, indicating a sensor malfunction or environmental interference rather than an actual fire.

Explanation: Raw logs show kitchen temperature dropping to ~2271°C (likely a unit scaling error in log display, but significantly lower than the rising trend seen earlier) while living room temp is stable at ~2384, ruling out a heat-based fire source.

Explanation: Occupancy sensors confirm no one was in the kitchen at 20:35, making 'unattended cooking' or human ignition unlikely.

Explanation: The simultaneous trigger of SmokeState=1 and ExpressedState=1 without corresponding high-temperature data points to a false positive caused by sensor drift, dust, or hardware failure.

Explanation: Other events (door unlock, window closing) appear consistent with automated security routines (auto-lock upon contact re-engagement) and do not indicate intrusion given the lack of sustained open states or forced entry evidence.

[2026-06-21T20:35:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2271

[2026-06-21T20:37:03] entrance_occupancy | OccupancySensing.Occupancy = 1

Inspect and clean the kitchen smoke detector immediately.

Test the detector battery and consider replacing the unit if cleaning does not resolve false alarms.

Review other sensor logs for similar temperature anomalies that might indicate systemic calibration issues.

Evidence of forced entry at night followed by undetected occupancy until morning and a subsequent CO alarm suggests an intruder accessed the home.

Explanation: Raw logs show a clear sequence of door contact opening (20:44:11) and automatic unlocking (20:44:12), immediately followed by window covering retraction (20:44:25) while the house was unoccupied since midnight.

Explanation: Occupancy sensors remained at 0 from midnight until 07:09 AM, creating a large time window where no one was detected inside despite active system events (window opening).

Explanation: The temperature spike in the kitchen (~30°C increase over ~8 hours) correlates with the CO alarm triggered at 16:19, indicating potential tampering or unauthorized use of appliances after the breach.

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

Dispatch security personnel to inspect the property for signs of forced entry and unauthorized appliance usage.

Check kitchen area for gas leaks or fire hazards related to the CO alarm.

Review video footage if available between 00:00 and 08:00 to identify the intruder's entry method and presence.

Zero occupancy readings across all monitored rooms starting from midnight

Check door contact sensor logs for breach duration between 20:44:12 and 20:44:25

Verify if the CO alarm was reset manually or triggered by a specific heat source event

Review camera feeds (if available) for the time range 20:00 - 08:00 to confirm presence/absence

Cross-reference smart plug usage (kitchen appliances) to see if cooking occurred before the CO alarm

触发安全警报，临时禁用 Keypad 输入，通知住户

Evidence strongly indicates a burglary attempt in the early morning followed by unauthorized entry and clearing of the residence.

Explanation: Empty house occupancy was confirmed from midnight until 05:47 when an occupant suddenly appeared in the bedroom.

Explanation: Immediately after occupancy was detected, there was a cluster of repeated lock operation errors at the front door (05:48:00-05:48:25) triggering a specific DoorLockAlarm (Code=3).

Explanation: The alarm was resolved approximately 1.5 hours later (07:09) with a manual unlock and subsequent window opening/closing sequence, which correlates with a resident or intruder securing the area after entry rather than a simple user error.

[2026-06-30T05:47:00] bedroom_occupancy | OccupancySensing.Occupancy = 1 (Home empty since 00:00)

Contact local law enforcement immediately to file a report regarding the suspected break-in.

Review security camera footage for the time range 05:40–07:15 to identify any external suspects or confirm internal movement.

Perform a thorough physical inspection of the home, including checking all windows and locked items, before re-entering if not already present.

CO 报警是严重安全事件，不同于烟雾报警

紧急通知所有住户撤离，开窗通风，联系燃气公司

A confirmed carbon monoxide alarm was triggered in the kitchen while the residence was unoccupied, indicating a potential gas leak or malfunctioning appliance.

Explanation: The CO alarm explicitly reported 'COAlarm()' and 'COState = 1' at 03:02, confirming a detection event rather than just a self-test.

Explanation: Housewide occupancy sensors recorded 'Occupancy = 0' for all rooms from midnight through early morning, confirming the resident was absent when the alarm sounded.

Explanation: Kitchen temperature readings showed a steady rise (from 2266 to 2381) during the incident period, suggesting an active heat source that may have caused the leak.

Immediately dispatch emergency services to investigate a possible CO leak in the kitchen.

Instruct the resident not to enter the kitchen until certified safe by professionals.

No security threat detected; the apparent absence of occupants and anomalous sensor readings are explained by a delay in occupancy detection following the homeowner's entry.

Explanation: The raw log shows the resident entered the house at 07:05 (door unlocked) and was detected in the bedroom at 07:07 (occupancy=1), establishing presence before the flagged events.

Explanation: The window covering actions at 12:29 and 14:01 occurred simultaneously with 'Occupancy=1' in the bedroom, directly contradicting the hypothesis that the room was empty during these times.

Explanation: The reported 'Occupancy=0' from midnight until shortly after 07:00 is consistent with a system lag or drift where motion sensors failed to register the resident immediately upon arrival but eventually corrected by 07:07.

Explanation: All other activities (cooking, locking doors) align with normal daily routines once occupancy data is reconciled.

[2026-06-11T07:07] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-11T12:29:10] bedroom_occupancy | OccupancySensing.Occupancy = 1

Review motion sensor sensitivity settings for the bedroom to reduce detection latency.

Verify battery levels of PIR sensors to rule out intermittent power issues causing delayed state changes.

WindowCovering.CurrentPositionLiftPercent100ths = 10000 (Open) at 12:29:16, 14:01:08, 20:36:24 while global occupancy is 0

FrontDoor LockOperationType=0 (Unlock) at 08:25:00 with OperationSource=Manual while all rooms are unoccupied

Check raw motion sensor PIR logs for false negatives or calibration drift during the periods when occupancy is reported as 0 but window coverings are moving.

Verify the timestamp accuracy and synchronization between the door lock controller and the window covering actuators.

Inspect camera footage (if available) specifically between 00:00-08:25 and 12:29-14:01 to confirm if anyone entered the bedroom or house.
