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

All identified signals (smoke alarm activation and window opening) are consistent with benign, non-threatening household activities.

Explanation: The smoke alarm triggered at 15:02 but automatically reset to '0' (normal) by 15:12 while occupants were present in the dining room, indicating a momentary nuisance or sensor glitch rather than an active fire.

Explanation: Temperature logs show no abnormal spikes or carbon monoxide readings; kitchen temperatures rose steadily from ~22°C to ~23.6°C between midnight and 3 AM due to heating/cooling cycles, which is within normal parameters.

Explanation: Window coverings were opened sequentially during evening hours (21:00 for kids, 22:18 for master bedroom) immediately after occupancy sensors detected residents entering those specific rooms, confirming routine human operation rather than unauthorized entry.

Explanation: No evidence of forced entry, tailgating, or prolonged unattended cooking exists in the provided logs.

Occupancy sensor data shows windows opened ([21:00:06], [22:18:11]) only after corresponding room occupancy events ([21:01:07], [22:18:09]).

Acknowledge the temporary smoke alarm signal as cleared; no further action required if no physical soot is observed.

Verify that battery alerts on smoke detectors have been replaced to prevent future false positives.

Multiple bedroom occupancy sensors reporting 0 at midnight.

Kitchen environment data (CO levels, temperature spikes, gas leak readings) around 15:00 on June 9th to confirm if smoke was real or false positive.

Access logs for the front door sensor to verify if any unauthorized access attempts occurred between 15:00 and 22:18.

Motion sensor logs in the children's room and master bedroom immediately following the window covering changes to determine if anyone entered the premises.

No security anomalies detected; the sequence of events indicates residents leaving home and securing the property manually before auto-relocking.

Explanation: The log at 17:41 shows a manual lock operation followed immediately by a door contact sensor reading 'False' (open), confirming the door was physically opened and then closed while being locked.

Explanation: A subsequent automatic re-lock event occurred at 22:34 after the door contact returned to 'True' (closed) and occupancy dropped, consistent with a resident returning or the system completing a secure cycle after evening activities.

Explanation: Occupancy sensors correctly show '0' from 00:00 onwards until morning activity resumes around 06:16, aligning with normal overnight vacancy rather than sensor failure.

CH-01-FP: 孩子生病请假在家（家长陪护）

家长也在家（多个房间有活动），不只是儿童房，说明有成人陪护

The anomalous '10000' window state values are identified as sensor drift/firmware bugs rather than intrusion, supported by the lack of concurrent motion alarms, normal occupancy patterns, and simultaneous occurrence in multiple rooms during automated routines.

Explanation: Occupancy sensors consistently report '0' (empty) across all rooms at 20:50 and 22:23, contradicting hypotheses of an intruder present or entering after closing curtains.

Explanation: The suspicious '10000' value appears simultaneously in the master bedroom window log at 22:23:11 (during automated night lockout), indicating it is a system-wide firmware quirk or overflow error rather than physical tampering.

Explanation: No motion sensor triggers, door contact violations, or forced motor events correlate with the curtain state changes, ruling out active break-in attempts.

[2026-06-16T20:50:10] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 combined with OccupancySensing.Occupancy = 0

[2026-06-16T22:23:11] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 occurring during Auto-lock sequence

Update firmware for window covering sensors to address the '10000' reporting bug.

Monitor logs for recurring non-physical state codes to refine threshold alerts.

[2026-06-16T07:18:33] front_door_lock | DoorLock.LockState = 1

If 10000 represents 'Open' and 0 represents 'Closed', the sequence (Close -> Open) could indicate someone trying to see out or access the window from outside after closing it initially.

If 10000 represents a specific error/tamper state, it directly signals security breach.

Household activity counts show significant presence in bedrooms (master: 12, second: 7, kids: 11) until late evening, making unauthorized entry less likely if residents were present.

Nighttime security protocol execution: System automatically locks all doors and confirms vacancy.

Event at 22:23:20 shows Auto-lock operation on front_door_lock.

Corresponding OccupancySensing.Occupancy = 0 across all rooms at 00:00:00 indicates the system has verified the house is empty.

Front door state confirmed as Locked (State=2) after 22:23:20.

Check raw IoT logs for kids_room_window motor current draw or battery voltage at 06:38:12 and 20:50:10 to distinguish between user control and forced movement/tamper.

Verify if any motion sensor triggers occurred in kids_room specifically between 06:38 and 20:50 that correlate with the curtain movements.

Cross-reference the '10000' value definition in the device firmware documentation to confirm if it maps to 'Open', 'Error/Tamper', or a specific limit switch hit.

The house is empty, but the kitchen temperature sensor is reporting physically impossible values (2264°C to 2409°C) indicating a severe sensor malfunction or data corruption rather than an actual fire or intruder.

Explanation: Occupancy sensors consistently report '0' for all rooms from 00:00 onwards, confirming the house is currently unoccupied and safe in terms of human presence.

Explanation: The 'kitchen_temp_sensor' logs show values starting at 2264 and rising to 2409. Since standard room temperatures are typically between 15-30°C, these values are clearly erroneous data points (likely a stuck integer counter or calibration failure).

Explanation: There is no evidence of active heating (temperature would be ~100°C if cooking) or smoke/fire detection; the anomaly is isolated to the raw numerical output of one sensor, ruling out a real thermal threat.

kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2264 (at 00:00:00)

kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2409 (at 04:00:00)

Immediately reset or replace the kitchen temperature sensor hardware.

Clear any false alarms triggered by this invalid temperature data from the security dashboard.

The manual door unlock at 07:15 occurred immediately after residents were detected inside the house (06:19), indicating a normal resident departure sequence rather than an intrusion.

Explanation: Occupancy sensors detected presence in the master bedroom at 06:19:00, confirming family members were still inside before the 07:15 door event.

Explanation: The front door contact sensor shows the door opening (False) at 07:15:35 and closing (True) at 07:15:38, followed by an automatic lock at 07:15:39, consistent with a resident leaving and the system securing the home.

Explanation: Subsequent logs show occupancy returning to '1' in the dining room at 07:16:06, further validating that humans are present and the house is not empty during the morning window.

No immediate action required; system behavior aligns with expected routine.

通过门锁合法进入（有效的临时 UserIndex），进出有完整的开锁+锁门记录

An unauthorized individual (UserIndex=5) entered the empty house via the front door, was detected inside by motion/temp sensors, and subsequently exited.

Explanation: Occupancy sensors confirmed the house was completely unoccupied from midnight until noon (00:00 to 12:00).

Explanation: At 12:06:00, a lock operation occurred followed immediately by the front door contact sensor opening (StateValue = False), indicating physical entry.

Explanation: Internal temperature sensors in the kitchen and living room showed a rapid, unexplained spike (from ~230°C reading to ~2520+ within minutes), which correlates with human presence generating heat in an otherwise stable environment.

Explanation: The intruder remained inside for approximately 10 minutes before unlocking and exiting at 12:16.

Immediately notify local law enforcement or security services.

Dispatch a trusted person to physically inspect the property if safe to do so.

通过门锁合法进入（有效的临时 UserIndex），进出有完整的开锁+锁门记录

The sequence of events indicates a standard evening arrival and departure routine where the front door was unlocked by UserIndex=5, briefly opened (confirmed by contact sensor), and then re-locked without any signs of unauthorized entry or forced exit.

Explanation: At 19:12:00, the lock state changed to 'Locked' (Type 1) via UserIndex=5, but immediately at 19:12:03, the `front_door_contact` sensor registered `False`, confirming the door was physically opened.

Explanation: Occupancy sensors in the kids' room remained active during this window, consistent with family members being inside rather than an intruder entering from outside.

Explanation: At 19:22:00, UserIndex=5 triggered another lock operation (Type 0), followed at 19:23:08 by the door contact returning to `True` (closed), completing a normal exit cycle for that user.

[2026-06-10T19:12:03] front_door_contact | BooleanState.StateValue = False

[2026-06-10T22:32:24] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Check if UserIndex=5 matches a known family member or guest profile.

Verify the physical state of the front door sensor immediately following the 19:12 and 19:22 events to confirm if the door was actually opened/closed versus just the lock cylinder turning.

Cross-reference with motion sensors in the entrance hallway and living room between 19:12 and 19:22 to see if someone entered the house after the initial lock event.

Temperature sensors are reporting physically impossible values (2281°C - 2364°C) instead of normal room temperatures (~20-25°C), indicating a critical sensor calibration or data transmission failure.

Explanation: Raw logs show temperature readings exceeding 2364°C in the kitchen and living room between 00:00 and 03:00.

Explanation: These values are physically impossible for residential environments and deviate drastically from the ~22°C range seen at other times.

Explanation: Occupancy sensors correctly report empty rooms during this period, ruling out overheating caused by human presence or equipment malfunction due to occupancy.

Explanation: The anomaly is isolated to specific sensor channels while lock and window logic operate normally, confirming a localized sensor fault rather than an environmental hazard.

[2026-06-03T03:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2364

Immediately flag the kitchen and living room temperature sensors for maintenance/replacement.

Manually verify ambient temperature in affected rooms with a physical thermometer.

Review historical sensor data to determine if this is a recurring drift issue requiring firmware update or hardware swap.

The system exhibits a complete and persistent failure of occupancy sensors across all zones while temperature sensors function normally, indicating a sensor network malfunction rather than an empty house.

Explanation: Occupancy sensors report '0' for every single zone continuously from 00:00 to 04:00 (a 4-hour window), which is highly improbable for a residential setting unless the house was vacated for travel or work.

Explanation: Temperature sensors are actively logging data with realistic values (ranging from ~22°C to ~23.8°C in raw units, likely scaled Kelvin or milliKelvin) and showing gradual changes consistent with heating cycles, proving the network is online and other sensors are functional.

Explanation: The simultaneous total blackout of motion detection in all rooms while environmental sensors remain active strongly points to a specific firmware bug, communication error, or calibration drift affecting only the occupancy module.

All `occupancy` logs consistently show `MeasuredValue = 0` from T=00:00 to T=04:00.

Concurrent `temperature` logs show valid, fluctuating measurements (e.g., 2267 -> 2391), confirming device connectivity and power.

Check local smart-home app for 'Device Offline' or 'Firmware Update Required' alerts on all motion sensors.

Manually test each room's motion sensor by walking through it to verify if the signal returns or if the entire network requires a factory reset.

Review recent system logs for communication errors or battery low warnings specifically related to the PIR/motion sensor cluster.

家长也在家（多个房间有活动），不只是儿童房，说明有成人陪护

The continuous zero occupancy readings combined with steadily rising temperatures indicate the house is empty and HVAC systems are off, consistent with a normal overnight scenario.

Explanation: All monitored rooms show 'OccupancySensing.Occupancy = 0' consistently from 00:00 to 04:00, which is expected for nighttime when residents are asleep or away.

Explanation: Temperature sensors show a steady increase (from ~22.6°C to ~24.0°C), confirming that heating/cooling systems are inactive due to lack of occupants; if someone were present or intruding, thermostat activity or human body heat would likely alter this trend differently, or motion would be detected.

Explanation: There are no logs indicating door breaches, alarm triggers, or sensor malfunctions (e.g., offline status); the data pattern aligns perfectly with a standard 'Away/Night' mode.

Consistent 'OccupancySensing.Occupancy = 0' across all zones for over 4 hours.

Steady temperature rise in kitchen and living room indicating HVAC shutdown.

No immediate action required; continue monitoring.

Ensure smart locks are engaged before departing tomorrow morning.

Continuous zero occupancy readings in the Entrance room at 00:00, 00:30, and 01:00 combined with zero occupancy in all bedrooms raises questions about whether anyone is actually home.

Complete silence (zero occupancy) across the entire property simultaneously for over an hour without any context of scheduled absence.

Door contact sensor states (open/closed) and door lock status logs around the times when occupancy dropped to zero to verify if doors were locked/unlocked.

Historical occupancy data for the last 24 hours to determine if the house was previously occupied and when the transition to 'empty' occurred.

Status of lights (on/off/dimming) and appliance states (AC, dishwasher) during the 00:00-01:00 window to see if systems are running consistent with 'home/away' modes.

Any network connection logs or device offline/online events that might explain a sensor failure causing false zero readings.

CH-05-FP: 孩子安静写作业后正常活动

虽然安静了1.5小时，但之后正常起身活动去了其他房间，说明只是在专注写作业

Temperature sensors are reporting physically impossible values (e.g., 2409°C) indicating a severe calibration failure or data corruption rather than a real thermal event.

Explanation: Occupancy logs consistently show 0 across all rooms between 00:00 and 04:00, suggesting the house is indeed empty or sensors are not detecting presence.

Explanation: However, temperature readings exhibit an exponential drift starting at 00:00:00 with values like 2273, 2288, 2304, reaching 2409 by 04:00.

Explanation: These values are physically impossible for a standard residential environment (indicating thousands of degrees Celsius), proving the sensor data stream is malfunctioning or corrupted.

BA-04-FP: 传感器触发延迟导致顺序看似跳跃

客厅occupancy在阳台和主卧之间有触发（2秒时），移动路径合理

The system logs indicate normal residential behavior with no evidence of unauthorized entry, intrusion, or malfunction; the reported 'anomalies' are explained by standard evening departure routines and automated night-time security protocols.

Explanation: Timeline analysis confirms a standard daily cycle: Residents left at 16:35, the home was secured manually at 17:59, and all occupancy sensors remained empty from 00:00 until the next morning (06:38).

Explanation: The event at 20:46 (window curtain opening to 100%) occurred while the house was vacant, but subsequent logs show the master bedroom light turning on at 20:47, indicating an authorized resident returned inside rather than an intruder entering via the window.

Explanation: The sequence at 22:23 shows the front door contact closing (secured) followed immediately by an auto-lock operation and lights turning off, which is consistent with a pre-programmed 'Good Night' routine triggered when the last sensor indicates vacancy, not an intrusion attempt.

[2026-06-25T20:47:00] master_bedroom_occupancy | OccupancySensing.Occupancy = 1 (Resident re-entered after window event)

Check motion sensor logs for the kitchen, entrance, and hallway between 18:00 and 21:00 to see if anyone entered before the window curtain was lowered.

Verify the source IP/MAC address or authentication token associated with the 'Manual' lock operation at 17:59:00.

Cross-reference the timestamp of the kids' room window curtain movement (20:46) with any video feed or other motion sensors in that specific room.

Check if the 'Auto' lock operation at 22:23:23 was triggered by a proximity sensor or a scheduled routine.

FG-03-FP: 烟雾报警器自检触发CO检测

The smoke alarm triggered a self-test sequence which temporarily simulated an active state, but the test completed successfully without any real fire conditions.

Explanation: Occupancy sensors across all rooms consistently report 0, confirming the house is empty and no one is present to experience a false alarm.

Explanation: Temperature readings are stable and within normal ranges (approx. 23°C), with no spike indicative of a fire source.

Explanation: The 'COState' flag changed to 1 at 18:01:05 exactly during the 'TestInProgress' window and reset to 0 immediately after 'SelfTestComplete()', proving the activation was part of the routine diagnostic cycle.

[2026-06-13T18:01:00] ... SmokeCoAlarm.TestInProgress = True

FG-03-FP: 烟雾报警器自检触发CO检测

Evidence strongly indicates an unauthorized entry event around midnight where the home was secured while occupants were absent, contradicting normal activity patterns.

Explanation: All occupancy sensors reported '0' (empty) across the entire house at 00:00:00, indicating no residents were present during the night shift.

Explanation: The front door contact sensor transitioned from Open (False) to Closed (True) between 22:11 and 00:00, followed immediately by an automated lock engagement at 22:11:28, suggesting a system-initiated secure state after an intrusion attempt rather than manual user action.

Explanation: Window coverings in the kids' room were fully open (100%) at 20:58 while the house was occupied, creating an opportunity for access that was not reset until 06:10 the next morning, implying the threat window existed unmonitored.

[2026-06-05T00:00:00] All rooms report Occupancy = 0
