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 confirmed carbon monoxide alarm triggered in the living room while occupancy sensors indicate residents were present and active in the house.

Explanation: The raw log explicitly records a 'COAlarm()' event at 14:12:00 with ExpressedState=2 (Active/Alarming) in the living room.

Explanation: Occupancy logs confirm residents were awake and moving (dining_room_occupancy=1) shortly after the alarm, ruling out an unattended appliance scenario as the primary cause without further context.

Explanation: Unlike standard smoke alarms, CO alarms are life-safety critical; the specific mention of 'COAlarm' rather than generic 'Smoke' indicates a gas leak or faulty heater, which is a distinct high-severity threat requiring immediate evacuation.

[2026-06-15T14:13:09] dining_room_occupancy | OccupancySensing.Occupancy = 1

Immediately evacuate all occupants from the premises to fresh air.

Contact emergency services (fire department) to report a suspected carbon monoxide leak.

Do not re-enter the home until professional technicians have verified it is safe.

Check if the CO alarm triggered a shutdown of gas appliances or sent a notification to mobile devices.

Verify user authentication logs for the 'Manual' lock/unlock operations to confirm if they were performed by registered users.

Check if the CO alarm was accompanied by temperature spikes or smoke detector activations in other sensors.

Review the exact timestamps of motion sensors in the entrance hallway during the 07:26 window to see if someone entered before the auto-unlock.

停止洗碗机运行，通知住户检查

The door unlock/lock cycle at 07:45 was a normal resident exit event confirmed by subsequent occupancy changes and the absence of unknown persons in the hallway.

Explanation: Occupancy logs show 'entrance_occupancy' as 0 immediately after the manual unlock at 07:45:27, indicating no one entered the house during that window.

Explanation: Door contact sensors confirm the door opened (False) for exactly 3 seconds before auto-locking, consistent with an authorized resident stepping outside quickly rather than a tailgating attempt.

Explanation: A legitimate entry event occurred later at 16:30 with matching manual unlock patterns, establishing that manual unlocking followed by auto-locking is standard user behavior.

触发入侵警报，通知住户，记录事件

The sequence of events represents a normal evening routine where residents opened windows for ventilation before bed and the smart home system automatically unlocked the door (likely due to a 'vacancy' or 'sleep mode' trigger) once all occupants were detected as asleep in their rooms.

Explanation: Occupancy logs confirm residents were present in the kids' room at 20:51 and the master bedroom at 22:22 immediately before the window openings, proving an authorized person was inside operating the devices.

Explanation: The front door unlock event at 22:22:30 is explicitly marked as 'Auto', indicating it was a system response to occupancy sensors detecting zero people in common areas/bedrooms, rather than a manual action by an intruder.

Explanation: No external intrusion indicators (e.g., forced entry, unknown motion sources) are present; the timeline aligns perfectly with residents settling down for sleep after opening windows.

[2026-06-01T20:51:00] master_bedroom_occupancy | OccupancySensing.Occupancy = 1 (Person present right before window open)

[2026-06-01T22:22:30] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Review smart home automation rules to understand why the front door unlocks automatically when occupancy drops to zero, ensuring this behavior aligns with user security preferences.

Verify that window locks are physically engaged if the house is intended to be secured against entry through windows during sleeping hours.

[2026-06-01T07:35:26] front_door_lock | DoorLock.LockState = 1

The tight temporal correlation between two separate windows opening late at night (20:50 and 22:22) and the subsequent immediate unlocking of the front door at 22:22:30 is statistically unlikely for routine behavior if no one was inside to open them. If residents were inside, why open windows so close to bedtime? Why unlock the door immediately after opening windows in different zones?

Temporal proximity: Kids' room window opened at 20:50:08, Master bedroom window at 22:22:25, Front door unlocked at 22:22:30.

Sequence logic: Opening multiple windows late at night followed immediately by unlocking the front door suggests an intruder entering through a window and then accessing the main entrance, OR residents leaving via the back while the system failed to detect the intrusion vector.

Lack of intermediate occupancy detection: No specific 'occupancy' event logged between the window openings and the door unlock, though sensor sampling rates may vary.

Check raw motion sensor data (PIR/Camera snapshots) for the period 20:45 to 22:30 specifically in kids_room, second_bedroom, and hallway leading to front_door.

Verify the source of the 'Manual' vs 'Auto' lock operations. Was the front door unlock manual or auto-triggered? If manual, who triggered it?

Review audio logs from smart speakers or cameras near the windows to hear sounds of breaking glass, climbing, or voices outside.

Cross-reference HVAC logs: Did the air conditioner turn off abruptly around 22:22 when the windows were opened, indicating a temperature change detection?

The system is in a normal unoccupied state with no evidence of intrusion, sensor failure, or environmental hazards.

Explanation: Raw logs confirm all occupancy sensors across every zone (living room, bedrooms, entrance, etc.) consistently report Occupancy=0 from 00:00 through 04:00.

Explanation: Temperature readings show a gradual rise consistent with HVAC operation or ambient changes after occupants departed, not indicative of fire or malfunction (no spike detected).

Explanation: The single LockOperation event at 19:47 was followed by a contact sensor state change to False (closed/locked), and no subsequent door opening events were logged, ruling out tailgating or forced entry.

All zone occupancy sensors reporting 0 since 00:00.

Front door contact sensor transitioned to closed state immediately after the lock operation at 19:47:03.

No action required; system status is normal.

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 is a normal resident leaving the house at night, confirmed by occupancy changes preceding the door interaction and consistent sensor states.

Explanation: Occupancy sensors detected presence in the master bedroom immediately prior to the incident (22:28:17), contradicting the hypothesis that the house was empty.

Explanation: The door contact sensor state transitioned from Closed (True) to Open (False) at 22:28:31, followed by an Auto-unlock command, indicating a legitimate departure sequence rather than forced entry.

Explanation: The window covering adjustment occurred minutes earlier while someone was still inside the bedroom, consistent with a resident preparing to leave.

Simultaneous drop to Occupancy=0 in ALL rooms starting at 00:00:00 while windows are being manipulated just prior

Check the `entrance_contact_sensor` state transition immediately before and after 22:28:32 to determine if the door was physically opened.

Verify the source of the `WindowCovering` commands at 21:14:10 and 22:28:26 (manual app control vs. smart scene automation).

Review `entrance_occupancy` history between 22:00 and 22:30 to see if anyone entered and left rapidly.

Cross-reference `living_room_occupancy` and `master_bedroom_occupancy` timestamps around 22:28 to confirm absence.

The event sequence represents a standard resident departure and return routine with no evidence of unauthorized entry or system malfunction.

Explanation: Occupancy logs show the house was empty from midnight until 06:23, followed by activity in the kids' room (lights on, window closed) indicating residents woke up or arrived.

Explanation: The manual lock at 07:21:26 immediately preceded the door contact opening at 07:21:28, confirming the authorized user opened the door to exit.

Explanation: The subsequent 'Auto' unlock at 07:21:33 is likely a system reset or sensor glitch triggered by the door closing, but the lack of occupancy change or intrusion attempt before the door opened rules out tailgating.

Explanation: Later events confirm normal behavior: residents returning (occupancy detected), doors locked manually upon exit, and windows auto-locking at night (22:11).

Evidence indicates a forced entry at 07:24 followed by unauthorized nighttime access to sleeping quarters while the system registered the home as empty.

Explanation: The sequence of Manual Lock (07:24:32) immediately followed by Auto Unlock (07:24:36) suggests a forced bypass or remote override rather than normal resident behavior.

Explanation: Nighttime window openings (21:10, 22:19) occurred while occupancy sensors reported '0' for living areas and bedrooms, indicating intrusion after residents left.

Explanation: The front door was unlocked (LockState=1) simultaneously with the nighttime window activations, providing an open path for entry.

Immediately change passwords/PINs for all smart locks, doorbell cameras, and associated mobile app accounts.

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

Secure the property physically by changing deadbolts if the lock mechanism was compromised, and review CCTV footage from external angles.

[2026-06-22T07:24:36] front_door_lock | DoorLock.LockState = 1

The specific sequence of Manual Lock -> Auto Unlock at 07:24 is highly irregular for a single household without explicit user confirmation logs.

Simultaneous opening of disparate windows (kids, master bedroom) at night when occupancy is zero suggests intrusion rather than routine cleaning or pet relief.

Front door LockOperation: Manual Lock (07:24:32) immediately followed by Auto Unlock (07:24:36) - < 5 seconds gap suggests system glitch or forced bypass.

Nighttime window openings (21:10, 22:19) occurring while Living Room/Dining/Master Bedroom occupancy sensors report '0'.

Front door remains unlocked (LockState=1) at 22:19:27, coinciding with nighttime window activations.

Authentication method for the 07:24:36 Auto unlock event (App command, Keypad code, or physical tamper?).

Motion sensor raw confidence scores around 21:10-22:19 to rule out false negatives.

Smartphone location history for authorized users between 21:00 and 23:00.

CCTV footage (if available) for the entrance foyer and hallway during the 07:24 and 22:19 timestamps.

Evidence confirms a fire hazard scenario where cooking was active and temperatures spiked significantly before triggering the smoke alarm, while no occupants were present to intervene.

Explanation: Kitchen temperature rose steadily from ~22°C to over 236°C (2368) between 01:00 and 03:00, indicating severe overheating likely caused by unattended equipment.

Explanation: Cooking surface ('kitchen_cook_surface') turned ON at 01:32, but no occupancy events were recorded in the kitchen or living room during this heating phase, suggesting an unattended cooking situation.

Explanation: The smoke alarm triggered exactly at 01:47 with SmokeState=1, confirming that the high heat resulted in a hazardous condition requiring evacuation or immediate intervention.

Explanation: Unlike the door/window events which showed clear manual user interaction patterns, the kitchen event shows a dangerous escalation of temperature without human presence.

[2026-06-02T01:30:00] kitchen_occupancy | OccupancySensing.Occupancy = 0

Immediately dispatch emergency services or contact the homeowner to verify safety.

Send smart home actuators to turn off the kitchen cook_surface if remote control is available.

Notify household members of the potential fire incident and advise them not to return until cleared.

[2026-06-02T22:16:22] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

No occupancy events recorded in these rooms between the window state changes might suggest no one was there to open/close them, or they were left unattended.

Check if the Kitchen Smoke Alarm triggered any other sensors (heat, CO, water leak) or if lights/appliances were automatically activated. Verify if the alarm was silenced manually.

Check the precise timestamp and duration of the front door 'LockState = 2' vs 'LockState = 1' transition at 07:21:24. Was there a contact sensor trip immediately preceding the unlock?

Verify the definition of '10000' for window covering position. Is it a valid state for fully open, or does it indicate a sensor failure/calibration error?

The midnight door lock event is a false positive caused by a sensor malfunction where temperature readings exceeded valid ranges (drifting into thousands), triggering a system logic error that interpreted the state change as a manual lock.

Explanation: All occupancy sensors consistently reported '0' (empty) from midnight to early morning, which is normal for a sleeping household and contradicts an intrusion scenario requiring someone inside.

Explanation: Temperature sensor data shows critical failures: values jumped from ~22°C to >2300°C at 00:00:00 and continued drifting upwards (>2370°C by 03:00), indicating a stuck or faulty sensor sending invalid data.

Explanation: System events often correlate with extreme sensor errors; the 'Locked' state at 00:00:00 likely resulted from the software attempting to secure the home due to the impossible temperature reading or a glitch triggered by the sensor reset/crash, rather than human action. The subsequent manual unlock at 07:17:10 confirms residents were present and managed the door normally.

living_room_occupancy | OccupancySensing.Occupancy = 0 (consistent through the night)

Replace or recalibrate the kitchen and living room temperature sensors immediately.

Review smart-home automation rules to ensure they do not trigger security actions based on out-of-range sensor values.

Verify physical integrity of the temperature probes for loose connections or short circuits.

Evidence indicates a successful burglary where an intruder entered the master bedroom, opened the window, and left through the unlocked front door after the occupants were absent.

Explanation: The front door was manually locked at 18:11 (likely by residents leaving) and remained closed until late night.

Explanation: At 22:40, the master bedroom occupancy sensor triggered (indicating presence), followed immediately by the window being fully opened.

Explanation: Crucially, the front door contact sensor changed to 'True' (open/unlocked state) at 22:40:23, just before the lock operation event at 22:40:24, suggesting the door was left ajar or manipulated during the intrusion exit.

Explanation: No re-entry or subsequent locking events occurred for the front door after 22:40, confirming the breach was not reset.

Multiple failed lock operations followed by an alarm indicate a mechanical jamming attempt or severe device failure at the front door during unoccupied hours.

Explanation: Four distinct LockOperationError events occurred in rapid succession (within ~40 seconds) between 02:10:00 and 02:10:25.

Explanation: An immediate DoorLockAlarm was triggered following the error sequence, indicating a breach attempt or security system detection of malfunction.

Explanation: Occupancy logs confirm the home was completely empty (all sensors reading 0) during the incident, ruling out normal internal activity.

Explanation: The lack of 'DoorContact' sensor toggles during the error window suggests the door may not have been successfully forced open, pointing to a jammed mechanism rather than a completed intrusion.

Occupancy sensors are reporting zero presence across all rooms while temperature sensors indicate continuous human activity (cooking/heating), suggesting a critical sensor failure rather than an empty house.

Explanation: Raw logs show occupancy sensors reporting '0' consistently from midnight to early morning, implying the house is unoccupied.

Explanation: However, kitchen and living room temperature sensors record values rising from 22°C to nearly 24°C with specific intervals, which strongly correlates with human cooking or heating activity.

Explanation: The simultaneous occurrence of high thermal activity and zero motion detection indicates the occupancy sensors are malfunctioning or stuck in a 'clear' state, creating a dangerous blind spot where a person could be present without triggering security alerts.

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 standard smart-home automated departure routine (Geo-fence exit) and subsequent return, with no evidence of unauthorized entry or intrusion.

Explanation: Occupancy sensors across all rooms showed '0' (vacant) during the night hours when the door unlocked at 22:44, confirming no one was inside to be displaced or intruded upon.

Explanation: The door unlock event at 22:44:15 is explicitly labeled 'Auto' and immediately followed by occupants entering (Master Bedroom occupancy = 1 at 22:44:09), consistent with a family member returning home triggering an auto-unlock feature.

Explanation: The window covering changes (closing at 06:16, opening at 21:18) are temporally separated from the door events and align with typical lighting schedules or manual morning routines rather than concealing an intruder.

[2026-06-02T00:00:00] ... OccupancySensing.Occupancy = 0 (All rooms empty during night)

[2026-06-02T22:44:15] front_door_lock | Event: LockOperation(... OperationSource=Auto) & DoorLock.LockState = 1

Review user settings for 'Auto Unlock on Return' to confirm it is enabled.

Verify that the Geo-fence radius matches the user's typical travel distance.

[2026-06-02T16:26:00] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual)

[2026-06-02T07:44:44] front_door_lock | DoorLock.LockState = 1

The gap between the last manual lock at 18:18 and the next manual lock at 06:16 includes an 'Auto' unlock event at 22:44, which is unusual for a standard leave/return pattern unless it's a scheduled smart-home routine not reflected in user logs.

Curtain state change in Kids Room at 06:16 (closing) vs Master Bedroom at 22:44 (opening) suggests conflicting human behaviors or automated schedules that don't align perfectly with a simple 'leave/return' narrative without context.

Door unlocked (State=1) at 22:44:15 while occupancy sensors indicate the house is empty (00:00:00 readings suggest vacancy around that window).

Children's room window coverings closed at 06:16:17 shortly after the door was unlocked/opened, potentially concealing an intrusion.

Discrepancy between 'Auto' unlock source at 22:44:15 and subsequent lack of manual re-lock until 06:16:17 (over 8 hours).

Detailed timestamps and sensor IDs for the 'Auto' unlock event at 22:44:15 to confirm if it was triggered by a geofence exit from a family member or a system glitch.

Motion sensor raw data (not just binary occupancy) between 22:44 and 06:16 to detect any movement in the house despite the '0' reading.

Timestamps and sources of all curtain/window covering changes to distinguish between automated schedules and manual manipulation.

Access log for the front door lock to verify who initiated the 'Auto' unlock operation (if available).

Repeated lock operation failures followed by an alarm indicate a mechanical failure or electronic interference at the front door, creating a potential security vulnerability.

Explanation: Multiple 'LockOperationError' events occurred in rapid succession (every ~15 seconds) between 08:04:00 and 08:04:40, indicating repeated attempts to engage or disengage the lock were unsuccessful.

Explanation: A 'DoorLockAlarm(AlarmCode=3)' was triggered immediately after the error sequence, confirming the system detected an abnormal state consistent with forced entry attempts or jamming.

Explanation: Crucially, raw logs show no motion sensors triggered at the entrance during this specific window (08:04), and occupancy remained zero, suggesting either a non-intrusive technical fault (e.g., battery drain, motor seizure) rather than an active physical break-in, but the risk of compromised locking capability remains high.

Absence of 'entrance_occupancy' = 1 or motion triggers during the error cluster

Immediately inspect the front door lock mechanism for physical damage, ice/obstruction, or tampering.

Test the lock manually and via smartphone app to isolate if the issue is hardware-based or software-based.

Replace the lock battery if voltage is low, as power fluctuation can cause operation errors.

Potential tailgating or unauthorized access attempt occurring between the initial successful lock/unlock sequence and the error sequence, possibly involving an external actor manipulating the lock mechanism.

Rapid succession of LockOperationError events (every ~15 seconds) immediately following the first successful manual operation and preceding the auto-unlock.

DoorLockAlarm triggered specifically after the error sequence.

No corresponding motion sensor triggers in the entrance hallway are listed in 'suspicious_signals', though this data might be filtered out as non-salient.

Raw contact_sensor logs for 'entrance' and 'front_door' around 08:04:00 to determine if the door was physically forced open or bypassed while locked.

Log source ID '3' details to confirm if it corresponds to an external keypad, smart phone app, or physical tamper switch rather than a user account.

Motion sensor raw data for 'entrance' and 'dining_room' immediately surrounding 08:04:00 to check for human presence when the lock system failed.

Voltage or power supply logs for the 'front_door_lock' to rule out battery failure causing false error codes.
