温度传感器读数漂移（drift）

Master bedroom sensors are functioning correctly, accurately reflecting occupancy changes consistent with the household's activity schedule.

Explanation: All master_bedroom_occupancy readings show logical transitions (0 when empty, 1 when people enter/activities occur).

Explanation: The sensor detected occupancy at 22:13:14 and reported it off at 22:13:34 after lights turned off, indicating no stuck state.

Explanation: There is no evidence of delayed detection or failure to report presence during active hours.

LockDoor 命令后 LockState 未变为 Locked
DoorLockAlarm (LockJammed) 触发
门锁故障意味着家庭物理安全降级

通知住户门锁可能卡住/故障，建议手动检查

The 'DoorLockAlarm' event is a standard system notification indicating the door was successfully locked via manual operation, not an intrusion or malfunction.

Explanation: Analysis of timestamps shows that at 23:33:15, the system logged 'DoorLockAlarm(AlarmCode=0)' immediately after a 'Command: LockDoor' and confirmed 'LockState = 2'.

Explanation: In this device's logic, AlarmCode=0 signifies a non-critical status update (successful lock confirmation) rather than a security breach or sensor failure.

Explanation: Crucially, the raw log confirms no intrusion occurred: the 'entrance_occupancy' sensor remained at 0 until 23:34:03, well after the locking sequence completed.

运动传感器高频率周期性触发 该房间无其他活动迹象（灯关、无门窗事件） 周期性极其规律（不像人类活动的随机性）

Master bedroom occupancy sensor is functioning correctly, showing consistent state changes (0 to 1) that correlate with door unlock events and subsequent activity in other rooms.

Explanation: The raw log shows the master_bedroom_occupancy sensor transitioning from 0 to 1 multiple times (e.g., at 00:00:00, 06:16:00, 15:56:00, 22:20:10), contradicting the hypothesis of a stuck '0' reading.

Explanation: These positive readings align temporally with front_door_unlock events and activity in other zones (kids_room, living_room), confirming the sensor detects presence when residents are home.

Explanation: The sensor remains 0 during late-night hours (e.g., 02:30:00) when no occupancy events are recorded elsewhere, indicating it correctly reports an empty room.

The master bedroom occupancy sensor is functioning correctly; the zero readings during the night align with normal sleep behavior and are corroborated by the absence of light/AC activity in that room at those times.

Explanation: Raw log shows continuous 'OccupancySensing.Occupancy = 0' for master_bedroom between 00:00 and 22:21, which is consistent with occupants sleeping.

Explanation: Corroborating evidence includes no activation of master_bedroom_light or master_bedroom_ac during these hours (only lights turn off at 22:21:37), indicating no active movement or system triggers occurred.

Explanation: The sensor correctly transitions to 'Occupancy = 1' at 20:53:00 when window coverings are opened and later at 22:21:23, proving it detects presence changes accurately.

Explanation: Contradiction regarding 'room_activity: 12' is likely due to data aggregation from other rooms or non-motion sensors, as the specific occupancy sensor itself reports consistently and logically.

The living_room smoke_alarm has confirmed a hardware fault and reported an expressed state indicating failure, rendering it non-functional.

Explanation: Stage-1 analysis identified a specific HardwareFaultAlert at 08:56:00 supported by raw logs.

Explanation: Raw log confirms the event 'HardwareFault()' was triggered on the living_room_smoke_alarm at exactly 08:56:00.

Explanation: The sensor also reported 'ExpressedState = 5' simultaneously, which typically denotes a critical error or offline status in smart home protocols, contradicting normal operation.

Explanation: No evidence suggests this is a false positive; multiple concurrent signals (alert flag + event + state code) confirm the physical device malfunction.

[2026-06-08T08:56:00] living_room_smoke_alarm | ExpressedState = 5

Immediately replace the battery or inspect the internal circuitry of the living room smoke alarm.

Manually test the remaining smoke detectors in the house to ensure they are operational.

Review maintenance logs for other sensors that may have experienced similar power or communication issues around 08:56:00.

The kitchen smoke detector has confirmed a hardware fault, and the temperature sensor exhibits erratic drift followed by total data loss, indicating a malfunctioning sensor suite in the kitchen.

Explanation: Stage-1 analysis identified a specific HardwareFaultAlert event for the kitchen_smoke_alarm at 11:40:00.

Explanation: Raw logs confirm this alert with explicit Event: HardwareFault() and ExpressedState = 5.

Explanation: Concurrently, the kitchen_temp_sensor shows physically impossible values (e.g., 2266 instead of ~22°C) starting at 00:00:00, suggesting calibration failure or drift prior to the reported fault, followed by a complete loss of signal (None) after cooking started at 18:18:30.

Explanation: No evidence supports fire occurrence; the anomalies are strictly technical failures of the sensing devices.

[2026-06-24T00:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2266

[2026-06-24T18:19:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None

Immediately replace or service the kitchen smoke alarm due to confirmed hardware fault.

Inspect the kitchen temperature sensor wiring and power supply to diagnose the cause of value drift and subsequent signal loss.

Verify the integrity of other sensors on the same bus/network segment to rule out systemic communication issues.

The master_bedroom occupancy sensor is functioning correctly; the reported '0' state at midnight corresponds to a time when no human presence was detected, consistent with normal overnight inactivity patterns.

Explanation: Raw logs show repeated 'Occupancy = 0' readings for master_bedroom between 00:00 and 03:00, which aligns with standard sleeping hours where no movement occurs.

Explanation: Contrary to H1's hypothesis of a failed sensor, the raw log explicitly shows the sensor reporting 'Occupancy = 1' at 22:10:22 (before sleep) and 16:22:00 (afternoon), proving the device detects presence when active.

Explanation: The later transition to 'Occupancy = 0' at 06:22:02 (morning) further confirms the sensor accurately reflects the absence of occupants during the night cycle.

通知住户该区域烟雾报警器失灵，建议立即更换，期间注意防火

The kitchen smoke alarm has confirmed a hardware fault, rendering the safety device non-functional.

Explanation: Raw logs explicitly show 'HardwareFaultAlert = True' and 'Event: HardwareFault()' for the kitchen_smoke_alarm at 22:08:00.

Explanation: No preceding sensor readings or successful reset attempts are visible in the log stream around the fault time, indicating a persistent failure rather than a transient glitch.

Explanation: While other sensors (temperature, occupancy) reported normal values, the specific critical failure of the smoke detector constitutes a direct anomaly.

Immediately inspect the physical kitchen smoke alarm unit for battery issues or damage.

Replace the smoke alarm if self-tests fail or replace the batteries if low power is suspected.

Test the replacement/new alarm to ensure it returns to normal operational state before dismissing the alert.

运动传感器高频率周期性触发 该房间无其他活动迹象（灯关、无门窗事件） 周期性极其规律（不像人类活动的随机性）

The master bedroom window sensor reported an impossible value (10000) indicating a firmware bug or communication error, not a physical state failure.

Explanation: Analysis of the raw log reveals a data packet at 22:45:27 where 'master_bedroom_window' reports 'CurrentPositionLiftPercent100ths = 10000'.

Explanation: A valid lift percentage in hundredths should range from 0 to 10000 (representing 0% to 100%), but the field name implies a scale where 100 represents 100%, making 10000 an out-of-bounds integer anomaly (likely a buffer overflow or parsing error).

Explanation: This is corroborated by a similar event for 'kids_room_window' at 20:59:08 reporting the same impossible value, suggesting a systemic software issue with window covering sensors rather than isolated hardware faults.

[2026-06-01T22:45:27] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

[2026-06-01T20:59:08] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Reset the master bedroom and kids room window covering devices to clear potential firmware glitches.

Update the firmware for all window covering sensors to address the parsing logic error.

状态 vs 实际位置不一致

The kids_room window covering actuator failed to complete a commanded 'Down' operation and entered an error state, indicating a mechanical or electrical fault.

Explanation: A manual command 'DownOrClose' was issued at 23:17:00 to the kids_room_window.

Explanation: Immediately after the command, the device reported status code 0b000010 (Error/Blocked) instead of transitioning to normal operation.

Explanation: At 23:17:30, the position sensor reported being stuck at exactly 50% (5000), confirming the actuator halted mid-movement due to the error condition.

Explanation: The raw log confirms no successful completion event or subsequent movement occurred despite the system remaining active.

温度传感器读数漂移（drift）

温度读数持续单向偏移，不符合正常日间温度曲线 其他传感器或空调自带温度显示不一致（如果可以交叉验证）

The occupancy sensor is functioning correctly; the midnight 'Empty' reading was a transient state consistent with no human presence in the room at that specific time, not a malfunction.

Explanation: At 2026-06-24T22:13:29, a window closure event occurred while the occupancy sensor still reported 'Occupied' (1) at 22:13:19, confirming the sensor was active and detecting presence shortly before the user left.

Explanation: From 22:13:29 until 06:18:00 (when the light was turned on), the master_bedroom_occupancy sensor consistently reported '0' (Empty). This sustained zero reading aligns perfectly with the absence of people in the bedroom during these hours.

Explanation: The reading of '0' at 00:00:00 is a valid negative detection (empty room) rather than a failure to detect presence, as the sensor later successfully detected occupancy when the resident returned at 06:18:03.

Explanation: All other sensors in the house followed similar patterns of reporting '0' during night hours, indicating a system-wide normal state rather than an isolated sensor fault.

门锁故障意味着家庭物理安全降级

The entrance sensor is functioning correctly; the system reports 'empty' occupancy during a period of confirmed inactivity (night hours) and no human activity.

Explanation: The raw log shows consistent 'OccupancySensing.Occupancy = 0' for the entrance from 00:00 to 12:34, indicating no motion detected.

Explanation: The lock events at 12:34 occurred while all room sensors reported empty, which is normal behavior for an automated locking sequence when no one is present inside.

Explanation: There is no contradiction between the high room_activity count mentioned in Stage-1 (likely metadata aggregation) and the actual raw event stream showing no occupancy triggers.

Absence of any OccupancySensor events or state changes in the raw log prior to the automatic lock command.

No action required; continue routine monitoring.

The kitchen smoke alarm has confirmed a hardware fault at 09:15:00, rendering it non-functional and creating a critical fire safety risk.

Explanation: Raw logs explicitly record 'HardwareFaultAlert = True' and 'Event: HardwareFault()' for the kitchen_smoke_alarm at 2026-06-10T09:15:00.

Explanation: The device also reports an invalid state (ExpressedState = 5), indicating internal failure or communication breakdown with the hub.

Explanation: While other kitchen sensors (temperature) are reporting data, the primary safety device in that zone is confirmed defective.

Immediately replace the faulty kitchen smoke alarm unit.

Verify battery levels and connections after replacement to ensure proper operation.

Global sensor reporting failure detected; no specific anomaly for the master bedroom as all sensors are uniformly stuck at zero.

Explanation: The raw log shows ALL occupancy sensors in the house (kitchen, living room, dining, bedrooms, bathrooms, entrance) reporting '0' simultaneously at every timestamp from 00:00 to 04:00.

Explanation: A uniform failure across an entire network of independent sensors strongly indicates a system-level issue (e.g., gateway crash, firmware freeze, or network partition) rather than a localized hardware fault in the master bedroom sensor.

Explanation: Since the hypothesis that the master bedroom sensor is individually malfunctioning (H1) contradicted by the global nature of the data, and there is no evidence of intrusion or safety risk due to the total lack of signal, the specific condition of the master bedroom cannot be determined as anomalous.

Simultaneous 'OccupancySensing.Occupancy = 0' readings for every single room sensor in the provided raw log.

Absence of any variation or activity logs for other rooms during the same timeframe.

Check the status of the central smart-home hub/gateway for connectivity or power issues.

The bedroom occupancy sensor is functioning correctly; it reported 'Empty' during the night when the home was inactive and registered 'Occupied' shortly after the resident entered in the morning.

Explanation: Raw logs confirm all rooms were empty (Occupancy=0) between 00:00 and 05:28, aligning with typical overnight absence.

Explanation: At 07:07, the front door was unlocked and opened, indicating resident arrival.

Explanation: Immediately following entry (within 1 minute), the bedroom sensor updated to Occupancy=1 at 07:08, proving the sensor successfully detected presence upon return.

Explanation: Subsequent logs show consistent state changes matching human activity patterns (e.g., lights on/off, window adjustments), ruling out a stuck or malfunctioning sensor.

[2026-06-16T07:08:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

Continue routine monitoring; no immediate intervention required.

Verify battery levels during next scheduled maintenance if low signal strength is suspected historically.

Raw PIR/Microwave log entries for `bedroom_occupancy` between 07:07 and 20:55 to check for actual motion triggers that were not reported as 'Occupancy=1'.

Battery voltage and signal strength logs for the `bedroom_occupancy` device to rule out power issues causing false negatives.

Timestamp correlation between `front_door_lock` unlock events and any subsequent `bedroom_occupancy` state changes to see if there is a lag or failure to register arrival.

The kitchen occupancy sensor is functioning correctly, showing intermittent presence during early morning hours which aligns with normal household activity patterns.

Explanation: Analysis of the raw log reveals that the kitchen_occupancy sensor did report 'Occupancy = 1' multiple times between 00:44:00 and 00:50:00 (specifically at 00:44:00, 00:44:35, and 00:45:10).

Explanation: This confirms the sensor is capable of detecting presence and is not stuck in a permanent 'empty' state as initially hypothesized.

Explanation: The reported activity in the kitchen (lights off at 06:57, door lock interactions nearby) supports the conclusion that these brief occupancy events correspond to legitimate human movement or interaction within the room.
