The sequence of events represents normal household automation and occupant routine, with no evidence of forced entry or unauthorized access.

Explanation: Occupancy logs confirm all residents were present in the house during the times windows/doors were manipulated (06:24 morning activity and 21:08 evening activity).

Explanation: The front door lock state change to 'Unlocked' at 22:47 is explicitly logged as an 'Auto' operation triggered immediately by the door contact sensor closing (indicating someone entered), which is standard behavior for auto-lock systems upon arrival.

Explanation: Window coverings (blinds) were moved manually via motor without any corresponding breach of window contact sensors or intrusion into the rooms, consistent with occupants adjusting lighting/view.

Time gap and logical disconnect between Kids Room blind manipulation (06:24 -> 21:08) and Front Door unlock (22:47).

Front Door Lock State change to Unlocked (1) at 22:47:20 immediately after Auto-lock failure or timeout logic might be suspected, though log says 'Event: LockOperation... Type=0'.

Absence of occupancy detection in Living/Dining/Kids/MasterBedrooms at midnight despite potential activity earlier.

Raw contact sensor logs for 'kids_room_window' and 'front_door_contact_sensor' to determine if windows were physically opened (not just curtains moved) and if the front door was breached before being locked/unlocked.

Motion sensor logs ('occupancy_sensor') specifically around 06:24 and 21:08 to see if human presence was detected in the kids' room when curtains changed position.

Detailed state history of the front door lock to distinguish between a user manually unlocking it vs. a system auto-unlock due to tamper or low battery.

Check if any smoke/co-alarm or water leak sensors triggered between 21:00 and 23:00.

The evidence indicates a routine family schedule where residents manually open/close the front door during their daily departures and returns, followed immediately by auto-locking.

Explanation: Occupancy sensors show consistent patterns: empty house overnight (00:00-06:36) matching departure, presence in bedrooms (07:37 AM, 16:32 PM) matching return/intermediate stops, and departure again (17:56 PM).

Explanation: Manual unlock events at 07:33:14, 16:33:00, and 17:56:00 are immediately followed by contact sensor changes (False then True) and subsequent Auto-Lock events within 9-18 seconds, confirming resident operation rather than forced entry.

Explanation: No motion sensor activations or window opening/closing anomalies occurred outside of expected times (e.g., kids room window opened at 06:36 before morning activity), ruling out hidden intruders.

Timestamp sequence showing Manual Unlock -> Contact Open -> Auto Lock within <1 minute for all three instances.

Correlation between occupancy state changes (e.g., Master Bedroom occupied at 07:37) and door lock cycles suggests internal user activity.

The event sequence represents a normal family routine involving children waking up and the household departing for the evening, with no signs of intrusion or unauthorized access.

Explanation: Occupancy logs show all rooms empty starting at 00:00, indicating residents have already left by the time the 'suspicious' lock event occurred at 17:52.

Explanation: At 07:25, children's activities (lights on, window opened) were followed immediately by door locking/unlocking and occupancy changes consistent with family members entering and then leaving.

Explanation: The lock event at 17:52 shows the door contact going open (False), but crucially, no new occupancy was ever detected in any room between 17:52 and 22:44; occupancy only returned to 1 at 22:44 when residents came back.

Explanation: The gap between manual lock (17:52) and auto-lock (22:44) is explained by the residents being out of range or not present to trigger an auto-lock upon re-entry until they actually returned late at night.

[2026-06-17T17:52:02] front_door_contact | BooleanState.StateValue = False

No occupancy sensor triggered 'Occupancy = 1' in any room between 17:52:00 and 22:44:19

Review video footage if available to confirm the visual nature of the 17:52 door interaction (likely a resident checking the door before leaving).

Confirm that the smart lock system correctly logs 'Manual' operations even when performed by authorized users who are currently outside the home network range.

The sequence of events represents a consistent household routine with no evidence of unauthorized entry or intrusion.

Explanation: Occupancy sensors confirmed the house was empty from 07:45 until 20:53, ruling out continuous intrusion during that window.

Explanation: The window opening at 20:53 in the kids' room occurred simultaneously with an entrance occupancy event (likely a resident returning), explaining the action as internal ventilation rather than external access.

Explanation: The master bedroom window opened at 22:38 immediately coincided with the front door unlocking and master bedroom occupancy sensor triggering, confirming residents were present and preparing for bed.

Explanation: All door lock operations were explicitly logged as 'Manual' or 'Auto' triggered by contacts, showing no signs of tampering, forced entry, or credential theft.

The observed events are consistent with normal household routines, specifically a resident performing an exit lock simulation or app-based locking/unlocking cycle while the house is vacant.

Explanation: Occupancy logs confirm the house was empty from midnight until 08:21 AM, making any physical intrusion impossible during the 05:25 AM and 07:09 AM windows.

Explanation: The 'Manual' lock operation at 07:09:07 followed by immediate 'Auto' unlocking at 07:09:13 matches known automation behaviors (e.g., testing the auto-lock feature after manually disengaging it) rather than forced entry.

Explanation: Door contact sensors correctly recorded the door opening (False) and closing (True) immediately surrounding the lock event, proving no prolonged unauthorized presence occurred.

[2026-06-10T00:00:00] ... bedroom_occupancy | OccupancySensing.Occupancy = 0

The specific timing of the manual lock/unlock cycle (Lock -> Unlock within 6s) is highly irregular for normal residential behavior unless simulating an exit/entry test, but combined with early morning curtain closure, it raises suspicion.

The discrepancy between high room activity counts and zero occupancy readings suggests either a system error or an intruder avoiding detection in rooms with motion sensors but triggering other sensors.

Raw GPIO/relay logs for the front_door_lock to determine if the 'Manual' source was actually a physical key turn vs. app command.

Motion sensor raw data streams for Kitchen, Living Room, and Bedroom between 05:25 and 07:15 to verify if any heat/motion signatures existed when occupancy reported 0.

Camera feed metadata (if available) around 05:25 and 07:09 to visually confirm who/what operated the locks and curtains.

System log entries regarding the transition from Occupancy=1 to Occupancy=0 to rule out sensor failure causing false negatives.

A confirmed unauthorized entry occurred when the front door was manually unlocked while the home was unoccupied, with subsequent occupancy detected inside.

Explanation: The raw log shows a manual lock unlock at 07:08:09 followed immediately by an automatic re-lock at 07:08:12, indicating an external interaction.

Explanation: Crucially, the entrance_occupancy sensor registered '1' (occupied) at 07:08:12, exactly when the door was re-locked, proving someone entered and was present inside.

Explanation: No legitimate user activity (e.g., lights turning on or other sensors activating) is recorded prior to this event, confirming the household was unoccupied.

The log shows a resident returning home at 06:58 and leaving at 08:20, with occupancy sensors confirming presence during these specific intervals.

Explanation: Occupancy logs show the house was empty until 06:59:00, when the bedroom sensor registered occupancy (1) immediately after the door was unlocked and opened.

Explanation: A second occupancy event occurred in the kitchen at 08:19:03, just before the manual lock operation at 08:20:00, indicating the resident was inside preparing to leave.

Explanation: Window covering movements (closing at 05:24, opening at 12:34) and light toggles align with a standard wake-up and departure routine for a single occupant.

Multiple instances of the front door being auto-unlocked followed by bedroom window coverings retracting occurred while all room occupancy sensors registered zero, indicating potential unauthorized entry or surveillance during unoccupied hours.

Explanation: Occupancy logs confirm all rooms were empty (value 0) at the critical times: 06:56 and 20:44.

Explanation: At both timestamps, the front door lock received an 'Auto' unlock command immediately after a contact sensor change (indicating someone was present), yet no resident was detected inside.

Explanation: Immediately following these door events, bedroom window coverings moved from closed to open (or vice versa in rapid succession), a behavior inconsistent with standard automated routines but consistent with an intruder testing sightlines or preparing for access.

Explanation: The correlation between the door unlock, the absence of occupants, and the subsequent window manipulation strongly suggests an intrusion event rather than a system glitch.

Evidence indicates a potential intruder attempted to enter the home around 06:54, triggered an automated system response that locked the door from the inside, but was subsequently detected by occupants.

Explanation: At 06:54:12, the front door contact sensor reported 'False' (open), indicating someone opened the door; however, at 06:54:19, the lock automatically engaged ('Auto') while the occupant had not yet arrived (next occupancy event is 08:32).

Explanation: The sequence shows the intruder likely entered, the smart home system detected the open state and auto-locked the door (perhaps failing to detect the intruder inside or reacting to a sensor glitch), leaving the intruder trapped outside or unable to gain full access until the resident returned.

Explanation: The subsequent manual locking at 08:34:00 by the resident (who arrived at 08:32) confirms they were unaware of the earlier incident and treated the home as needing immediate re-securing.

[2026-06-04T06:54:12] front_door_contact | BooleanState.StateValue = False

No occupancy events recorded between 06:54 and 08:32, suggesting the resident was absent during the breach attempt.

Contact local authorities to file a report regarding the unauthorized entry attempt at 06:54.

Inspect the front door area for signs of forced entry or tampering.

Review smart lock logs to determine why the 'Auto' trigger occurred without explicit user authorization in the absence of occupants.

[2026-06-04T20:37:19] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Rapid transition of front door lock from 'Locked' to 'Unlocked' within seconds (06:54:10 - 06:54:19).

Bedroom window covering set to fully closed (0%) at 05:37, preceding the first manual door lock event.

Front door lock operation source listed as 'Auto' during a critical timeframe, which may indicate a hijacked smart lock or automated response to a sensor trigger not visible in this summary.

Check the occupancy sensor logs for the kitchen and living room around 06:54 to confirm if anyone entered/ exited before the lock change.

Verify the 'Auto' source of the 06:54:19 lock unlock event; check if it triggered by a specific sensor (e.g., smoke, water leak) or indicates a system failure/hack.

Review the bedroom window contact sensor status concurrent with the window covering movements to see if the window itself was physically opened/closed.

Analyze the command history for the smart lock to determine if the 'Manual' vs 'Auto' classification is accurate or if there was a communication lag.

No security threat detected; all events correspond to normal resident behavior including automated window adjustments and routine locking patterns.

Explanation: Occupancy sensors remained '0' (empty) from midnight until the next morning light sensor event at 05:33, ruling out unauthorized entry during the night.

Explanation: The window closing event at 14:05 was immediately followed by occupancy detection in the living room at 14:05:04, confirming a resident was present to adjust curtains.

Explanation: Door lock operations show a consistent pattern of manual locking upon departure (07:00, 08:31) and automatic unlocking upon return (20:46), with no evidence of forced entry or tampering.

[2026-06-15T00:00:00] ... OccupancySensing.Occupancy = 0 (throughout night)

[2026-06-15T14:05:04] living_room_occupancy | OccupancySensing.Occupancy = 1 (confirms presence during curtain adjustment)

Continue monitoring standard daily logs.

Verify smart home automation schedules if window actions become inconsistent with occupancy data in future.

Door lock state changed to UNLOCKED (1) shortly after evening arrival (20:46), despite previous manual locking events.

Check raw motion sensor logs for entrance/bathroom/bedroom between 00:00 and 14:05 to confirm if anyone entered the property.

Verify the specific timestamp and trigger mechanism for the 'window closing' event at 14:05:02 (was it automated by a smart curtain system or manual?).

Cross-reference with camera footage if available around 20:46 to see who operated the door lock upon return.

A confirmed physical intrusion occurred in the early morning while the home was unoccupied and locked, indicated by a door contact breach immediately following a manual lock operation.

Explanation: Occupancy sensors recorded '0' for all rooms from 00:00 until 08:31, confirming the house was empty during the incident window.

Explanation: At 06:53:03, a manual lock operation was triggered, followed immediately at 06:53:05 by the front door contact sensor reporting 'False' (open), indicating the door was forced or opened despite being locked.

Explanation: The contact sensor returned to 'True' (closed) at 06:53:11, suggesting an intruder entered, stayed briefly, and left before the system auto-unlocked or another event reset the state.

Explanation: Subsequent occupancy detection at 08:31 confirms residents were absent during this entire sequence, ruling out normal resident activity.

Manual lock operation (Type 1) immediately followed by Auto unlock (Type 0) without a preceding occupancy event in the entrance area.

Timestamped logs for 'entrance_occupancy' around 06:58 to confirm if an intruder entered before the door was locked.

Raw binary data or firmware-level logs for 'front_door_lock' at 06:58:04 to determine if the lock was physically tampered with vs. remotely unlocked.

Historical logs for 'bedroom_contact_sensor' (window sensor) between 05:37 and 20:52 to verify if windows were physically opened/closed despite curtain motor commands.

The system experienced a prolonged sensor failure (occupancy sensors stuck at '0') while the resident was present and active inside the home, confirmed by manual door interactions and eventual occupancy detection.

Explanation: Raw logs show all occupancy sensors reported '0' from 00:00 until 06:53, despite the resident manually operating the front door lock at 06:52:09 and 08:26:00, which requires physical presence or remote control. If an intruder were present, they would likely trigger motion sensors unless using advanced masking, but the subsequent detection of occupancy at 06:53:00 confirms the resident was inside the entire time.

Explanation: Temperature readings rose steadily from 22°C to 25°C between midnight and 1 PM, indicating normal heating usage by a living person, contradicting the theory of an empty house or a stealthy intruder avoiding heat signatures.

Explanation: The discrepancy is fully explained by a 'sensor_stuck' or 'sensor_malfunction' event where occupancy logic failed to register presence for ~7 hours, rather than a security breach.

[2026-06-26T06:52:09] front_door_lock | Event: LockOperation... OperationSource=Manual

[2026-06-26T06:53:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

Continuous temperature increase (2267 -> 2508) during the period of zero occupancy reports

Check connectivity and power supply for all occupancy sensors to rule out network issues causing data suppression.

Review firmware settings for occupancy sensors to ensure sensitivity thresholds are appropriate for the current lighting/environmental conditions.

Notify the homeowner about the temporary sensor failure log entry; no security alert action is required.

Multiple rapid state changes on bedroom window covering (0 -> 100 -> 0 -> 100) within short intervals without corresponding motion events seems mechanically inconsistent with natural human behavior.

Total occupancy = 0 across all rooms at 00:00:00 and 00:30:00, yet manual door lock operations occur shortly after at 05:28 and 06:52.

Bedroom window coverings toggling rapidly (0% -> 100% -> 0%) between 06:52 and 14:01 without any associated motion sensor triggers in the bedroom.

Discrepancy between 'Manual' lock operations and global '0' occupancy status implies either the resident is invisible to sensors or someone else is controlling the house remotely/on-site.

Check raw camera footage or microphone logs for audio/visual confirmation of presence inside the home during the 05:28 - 08:26 timeframe.

Verify if the '0' occupancy readings are due to sensor calibration errors, power loss, or intentional masking.

Cross-reference the timestamp of the first manual door lock (05:28:08) with the time the curtains were fully open (05:28:08) to determine if they happened simultaneously or sequentially.

No security threat detected; the sequence of events corresponds to a normal resident waking up, leaving for the day, returning later, and settling down for sleep.

Explanation: The raw logs confirm a continuous occupancy timeline: resident absent from midnight until morning activity starts at 05:40 (lights/window), followed by departure around 07:10-08:20, return around 12:20/14:05, and final departure/sleep cycle at 20:49.

Explanation: The rapid lock/unlock sequence at 07:10 is explained by the door contact sensor toggling (False then True) immediately before the auto-lock, indicating a standard 'door opened/closed' event during exit rather than forced entry or glitching.

Explanation: All observed behaviors (window opening/closing, temperature fluctuations consistent with HVAC cycles, manual locking upon exit) align perfectly with Hypothesis H1 (routine daily activities) and contradict Hypothesis H2 (burglary).

[2026-06-09T07:10:08] front_door_contact | BooleanState.StateValue = False followed by [2026-06-09T07:10:11] ... True

Occupancy sensors show clear gaps matching a full workday schedule (00:00 to ~08:20 absence, re-entry at 12:22, final absence at 20:49).

Continue monitoring standard daily patterns.

High overall event count (1851) and salient events (60) suggest a complex but likely legitimate sequence of daily life rather than a silent break-in which often triggers fewer distinct sensor events if no alarms sound.

No smoke, leak, or emergency alarm signals present in the suspicious list.

Timestamped logs between 07:10:00 and 07:10:20 to determine the exact sequence of state changes and if there was a gap where the door was unlocked/unsecured.

Motion sensor logs for entrance and living_room immediately before and after the 07:10 lock events to confirm if someone entered/exit physically.

Camera footage (if available) or detailed access logs for the front_door_lock around 07:10 to verify if the manual lock was successful or if there were multiple failed attempts.

Contextual data for the bedroom window movements to see if they correlate with light levels or external temperature changes.

Temperature sensors are reporting physically impossible values (e.g., 2504) indicating a firmware or calibration failure rather than an actual fire or intrusion event.

Explanation: Occupancy sensors consistently report '0' until the resident's morning routine at 06:50, which is consistent with an empty house and contradicts the hypothesis of an intruder entering while the house was occupied.

Explanation: The temperature sensor data shows a linear drift from ~22 to ~25 degrees Celsius overnight, which is normal for cooling off, but then abruptly jumps to 2504.0°C at 06:50, a value physically impossible for ambient air.

Explanation: The door contact sensor toggles normally between False (open) and True (closed) during the 06:50 sequence, confirming that motion/contact sensors are functional, isolating the anomaly to the temperature reading.

[2026-06-22T06:50:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2504

[2026-06-22T06:50:12] front_door_contact | BooleanState.StateValue = True

Ignore the high temperature alert as a false positive caused by sensor malfunction.

Check physical hardware wiring or replace the kitchen temperature sensor.

Verify if other sensors in the kitchen exhibit similar drift errors.

Complete absence of occupancy sensors across all rooms at 00:00:00 suggests the resident is not home, yet no forced entry alarm or motion detection in common areas is logged between midnight and the first activity at 06:50.

Check motion sensor raw data for any transient movement in living_room or hallway between 00:00:00 and 06:50:00.

Verify if the front_door_lock contact sensor was ever tripped (open state) between 00:00:00 and 06:50:00, which would indicate an attempted break-in before the manual locking event.

Review camera feeds (if available) or audio logs from the entrance and living room around 00:00:00 to confirm silence/emptiness versus potential undetected presence.
