The living room occupancy sensor is functioning correctly; the zero reading at 00:00 represents a scheduled system reset consistent with other sensors and the absence of human activity during that time.

Explanation: All occupancy sensors across the house reported '0' at 00:00:00, indicating a synchronized daily reset or maintenance window rather than an isolated device failure.

Explanation: No occupancy events were logged for the living room between 00:00 and 06:44 (when the first activity occurred in another room), which aligns perfectly with the expected period of no human presence.

Explanation: When human activity did occur later in the day (e.g., kids_room_occupancy at 07:44), the sensor responded normally, proving the device is not stuck or malfunctioning.

Absence of any living_room_occupancy readings between midnight and 06:44:10

Master bathroom occupancy sensor is functioning correctly; all rooms remain unoccupied during the night cycle until morning wake-up.

Explanation: The raw log shows consistent 'Occupancy = 0' for master_bathroom and all other rooms from 00:00:00 to 06:49:05, indicating a normal empty state throughout the night.

Explanation: There are no gaps in the data stream or missing packets that would suggest sensor malfunction or communication failure.

Explanation: Activity resumes normally at 07:11 with door locking/unlocking events, followed by occupancy detection in bedrooms at 07:13:00, confirming the sensor system activates upon human presence as expected.

Entrance sensors are functioning normally; occupancy detection and lock state transitions align perfectly with expected human activity patterns.

Explanation: Occupancy sensor reports 0 (empty) during the overnight period (00:00-06:14), which is consistent with normal household behavior.

Explanation: At 07:28:25, a manual unlock event occurred immediately followed by the door contact opening (False) and entrance occupancy turning to 1, indicating correct detection of arrival.

Explanation: The system automatically re-locked the door at 07:28:28 after confirming occupancy, showing logical state management without glitches or missed detections.

Explanation: No gaps in transmission or contradictory state changes were observed in the provided log snippet.

Timestamp sequence: LockUnlock -> ContactOpen -> Occupancy=1 -> AutoLock within seconds.

The sensor is functioning correctly; the '0' readings represent a normal period of unoccupancy consistent with nighttime hours and later confirmed by genuine occupancy detection upon waking.

Explanation: All occupancy sensors across the house reported '0' at midnight (00:00:00), indicating a system-wide state of inactivity rather than an isolated device failure.

Explanation: The master_bedroom_occupancy sensor successfully transitioned to '1' at 06:33:00 when activity resumed, proving the sensor detects presence effectively after being dormant.

Explanation: The sensor reported '1' again at 22:25:12, aligning perfectly with the window opening event and subsequent light turning off, confirming accurate real-time detection capabilities.

The dining room occupancy sensor is functioning normally; the reported zero values are consistent with the empty state of the house during the night and early morning hours.

Explanation: All occupancy sensors across multiple rooms (living_room, master_bedroom, kids_room, etc.) simultaneously report '0' at timestamps 00:00, 00:30, and subsequent intervals until activity resumes in the afternoon/evening.

Explanation: This global consistency indicates a valid system-wide state where no one is present, rather than a localized sensor failure or data corruption.

Explanation: No motion events or door unlock events occur in the dining room area between midnight and 16:17, confirming the physical absence of occupants that matches the sensor readings.

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

Simultaneous zero readings from all other room occupancy sensors (e.g., living_room, master_bedroom) at the same timestamps.

First positive occupancy event for any room occurs at 16:17:30 (entrance), validating the empty state prior to this time.

Continue monitoring standard daily operations.

No immediate maintenance required for dining_room_occupancy_sensor.

The dining_room occupancy sensor is functioning normally; the synchronized zero readings at midnight are consistent with a house-wide schedule-based lockdown or system initialization event, not a hardware failure.

Explanation: Multiple zones (kitchen_temp_sensor, living_room_occupancy, etc.) reported synchronized data at exactly T+00:00:00 and T+01:30:00, indicating a systemic trigger rather than isolated sensor malfunction.

Explanation: Occupancy sensors in high-traffic areas (entrance, master_bedroom) correctly transitioned to '1' upon door unlocking and human entry events later in the day (e.g., 07:10:25, 16:06:02), proving the sensors are responsive to actual presence.

Explanation: The lack of dining room temperature data is an informational gap but does not constitute a functional anomaly for the occupancy sensor itself, especially given the logical consistency of the occupancy state with other active sensors.

The kids_room sensors are functioning normally; the reported '10000' value for window coverings is a valid protocol representation of 100% open, and occupancy data aligns with the absence of activity events during the monitored period.

Explanation: The suspicious signal 'WindowCovering.CurrentPositionLiftPercent100ths = 10000' at 20:41:04 corresponds exactly to the master_bedroom_window event at the same time (also 10000), indicating this is a standard telemetry encoding for 100% lift rather than an overflow error.

Explanation: There is no evidence of sensor malfunction or drift in the kids_room: the raw logs show zero occupancy readings throughout the night and early morning, which is consistent with the lack of any 'OccupancySensing.Occupancy = 1' events recorded for that room between 00:00 and 22:18.

Explanation: The system correctly registered room activity (light on at 06:43) and subsequent state changes without missing detections, confirming the sensor chain (occupancy and window covering) is operational.

The sensor is functioning correctly; the reported '0' occupancy reflects actual empty room conditions during the monitoring window, consistent with periodic polling intervals.

Explanation: Raw logs confirm master_bathroom_occupancy consistently reports '0' at regular 30-minute intervals (00:00, 00:30, 01:00, etc.), indicating normal heartbeat behavior rather than a stuck state.

Explanation: All other room sensors (living_room, bedrooms, etc.) also report '0' simultaneously, establishing a baseline that the house was unoccupied during this late-night/early-morning window.

Explanation: The previously noted '8 activity events' in summary statistics likely refer to non-occupancy metrics (e.g., temperature readings, light status changes, or system heartbeats) which do not contradict an empty room state.

Check the raw event stream for master_bathroom between the timestamps where 'room_activity' indicates 8 events. Verify if the payload of these events relates to occupancy transitions (e.g., 0->1 or 1->0) or other attributes (light dimming, leak detection).

Compare the timestamp resolution of the 8 master_bathroom events against the 30-minute polling interval shown in suspicious_signals. Determine if the '0' reports are periodic heartbeats or continuous state holds.

Cross-reference with water_leak_detector and onoff_light logs in master_bathroom to see if any interaction occurred that might have triggered an occupancy-related automation rule.

The second_bathroom occupancy sensor is non-functional as it fails to report status while all other room sensors operate normally at regular intervals.

Explanation: All monitored rooms (kitchen, living_room, master_bedroom, etc.) consistently report occupancy data at expected intervals (e.g., every 30 minutes).

Explanation: The 'second_bathroom_occupancy' identifier appears zero times in the provided raw log excerpt spanning from 00:00 to 04:00.

Explanation: This complete absence of telemetry creates an asymmetry with adjacent rooms (like master_bathroom) which are fully functional, indicating a hardware or communication failure specific to the second_bathroom device.

Absence of any log entry containing 'second_bathroom_occupancy' in the entire timestamped dataset.

Presence of identical timestamps and successful reporting for 'master_bathroom_occupancy' confirms system-wide logging functionality is active.

Check physical connectivity (power/battery) of the second_bathroom occupancy sensor.

Inspect network gateway logs for packet loss or ACK failures specific to the second_bathroom subnet.

The entrance sensor is functioning correctly; the apparent discrepancy between activity counts and occupancy readings is due to a sampling interval difference rather than a malfunction.

Explanation: Raw logs show specific timestamps where entrance_occupancy reported '1' (occupied) at 16:25:31, 17:56:03, and others, correlating with door lock operations and human movement.

Explanation: The log entries showing '0' for entrance_occupancy occur strictly at regular intervals (00:00, 00:30, 01:00, etc.), indicating these are scheduled status snapshots rather than continuous real-time tracking.

Explanation: Since the sensor successfully detects presence during actual events (e.g., 16:25:31), it is not stuck in an 'empty' state or malfunctioning; the earlier hypothesis of a persistent fault was contradicted by the raw data.

The kitchen temperature sensor exhibits a sustained and unrealistic linear increase in readings (from ~22°C to ~23.6°C) over a 4-hour period with no corresponding occupancy or appliance activity, indicating a hardware malfunction or calibration failure.

Explanation: Normal ambient temperatures typically fluctuate within a few degrees; the observed rise of ~1.5°C per hour is physically impossible for a passive environment without an active heat source.

Explanation: The log shows zero occupancy events in the kitchen during the heating interval, ruling out cooking activities as the cause.

Explanation: The living room sensor shows similar but less extreme drift, suggesting a systemic issue with temperature sensors (e.g., unit conversion error from millikelvin/centidegree to Celsius) rather than a localized fire event.

Explanation: No other safety systems (smoke, leak) were triggered despite the apparent 'heating', further supporting a sensor data integrity issue.

The dining room occupancy sensor is functioning correctly; initial zero readings were due to system initialization, and subsequent detections align perfectly with human activity events.

Explanation: Initial timestamps at 00:00:00 show all sensors reporting 'empty', which is consistent across multiple rooms and temperatures, indicating a system boot or synchronization event rather than sensor failure.

Explanation: The first positive detection for the dining_room_occupancy sensor occurs at 07:21:09 (Occupancy=1), exactly matching the time of a manual front door unlock and entry event recorded at 07:20:16-07:20:19.

Explanation: A second positive detection occurs at 20:54:03, correlating with the closing of curtains in the kids' room, suggesting household members are present and active in the house, validating the sensor's ability to detect presence when occupied.

Explanation: No gaps or stuck states are observed once the system becomes active; the sensor transitions from 0 to 1 appropriately upon entry.

The kids_room window covering actuator appears to be stuck or non-responsive, failing to track position changes between fully closed and fully open states without any corresponding command events in the log.

Explanation: Evidence shows a sudden jump in `WindowCovering.CurrentPositionLiftPercent100ths` from 0 to 10000 (fully open) at 21:19:04.

Explanation: There are no manual 'Open' commands or automation triggers recorded for `kids_room_window` around this timestamp.

Explanation: The same behavior is observed for `master_bedroom_window`, suggesting a potential system-wide sensor/actuator sync issue or specific hardware failure in that room's motor encoder.

Explanation: Unlike the occupancy sensors which show a consistent daily reset pattern across all rooms (likely a scheduled zeroing), the window state change lacks any logical trigger.

Inspect the physical window covering motor in the kids' room for mechanical obstruction or motor failure.

Verify if other devices in the house exhibit similar erratic state reporting to rule out a central hub communication glitch.

Force a manual calibration of the window cover sensor if accessible via local controls.

The occupancy sensor in second_bedroom is functioning correctly, reporting consistent empty states during the night and no unexpected activity.

Explanation: During the entire overnight window (00:00 to 03:00), second_bedroom_occupancy consistently reported '0', matching the status of all other rooms which were also unoccupied.

Explanation: There were no sporadic positive detections ('1') or rapid state fluctuations that would indicate a sensor stuck or ghost trigger.

Explanation: The first occupancy detection for any room occurred at 07:52 in master_bedroom, coinciding with front door unlock events, confirming sensors activate only upon actual human presence.

[2026-06-24T00:00:00] ... [2026-06-24T03:00:00] second_bedroom_occupancy | OccupancySensing.Occupancy = 0

The occupancy sensor reading of 0 at midnight is consistent with the absence of occupants in the room during early morning hours, and subsequent logs show normal activity cycles.

Explanation: Raw logs confirm kids_room_occupancy reported 0 from 00:00 until 06:16, indicating no motion detection during this period.

Explanation: Activity in the kids_room only resumed at 06:16 (lights on) and 20:51 (window opened), which aligns with a child sleeping through the night and waking up later.

Explanation: The initial hypothesis of a 'false negative' due to an occupant being present at midnight is contradicted by the lack of any other indicators (light/window events) for presence during that specific window.

Explanation: However, at 2026-06-16T22:43:19 (6 seconds later), the same sensor reports no change or an invalid state context given the subsequent light turn-off at 22:43:36, and critically, the window sensor reports '10000' (invalid) at 22:43:19.

Explanation: The simultaneous occurrence of an invalid sensor value ('10000') for the window covering and potential data stalling or logic failure in the occupancy sensor suggests a firmware glitch or communication error affecting multiple devices in that zone or device type, rather than a physical anomaly like intrusion.

Explanation: The door lock state change at 22:43:29 corresponds to the 'Auto' unlock event which triggered the entry, validating the timeline but not the sensor's ability to track the post-entry state.

[2026-06-16T22:43:13] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-16T22:43:19] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Check firmware versions and restart the master_bedroom occupancy and window cover sensors.

Verify if other devices with similar models are experiencing '10000' read errors elsewhere in the system.

Inspect power supply stability for devices in the master bedroom area.

Cross-reference door lock logs with master bedroom motion sensor logs between 22:43:00 and 22:45:00 to see if someone entered while the room showed empty.

Check system clock synchronization across all devices, as timestamps like '10000' might indicate time-related overflow issues.
