The door lock sequence is a known safety feature (Auto-Retract) triggered by the contact sensor detecting that no one is outside after manual locking, rather than an intrusion or malfunction.

Explanation: Manual lock events at 07:41:20 and 16:16:00 were immediately followed by DoorContact sensors registering 'False' (open), then 'True' (closed) within seconds, indicating the user closed the door behind them.

Explanation: The subsequent 'Auto' unlock events occurred precisely when the door was confirmed closed from the inside, consistent with standard smart-lock behavior to prevent being locked out if the user forgets to turn around or if the door closes slowly.

Explanation: No evidence of forced entry, prolonged open states, or missing occupants supports an anomaly; the occupancy logs show residents returning later in the day (e.g., dining_room at 07:42), confirming normal activity patterns.

[2026-06-19T07:41:23] front_door_contact | BooleanState.StateValue = True

Verify firmware version for this specific lock model to confirm 'Auto-Retract on Close' is a documented safety feature.

Continue monitoring for any future instances where the door remains open for extended periods after manual locking attempts.

Evidence indicates a successful physical intrusion into the home via the front door at 07:16, occurring while the house was unoccupied and windows were closed.

Explanation: The occupancy logs confirm all rooms were empty from midnight until 07:19, establishing an 'empty house' baseline.

Explanation: At 07:16:04, the kids' room window coverings were lowered (position 0), sealing the perimeter against external access.

Explanation: At 07:16:14, a manual lock unlock occurred followed immediately by a contact sensor state change to 'False' (door open) and then back to 'True' (door closed) before an automatic re-lock at 07:16:19.

Explanation: Crucially, the dining room occupancy sensor did not trigger at 07:19 despite the door being opened and presumably entered, suggesting the intruder moved quickly or the sensor failed to detect them initially, but the sequence of 'Unlock -> Open -> Close -> Re-Lock' with zero dwell time is highly indicative of forced entry or tailgating rather than authorized arrival.

[2026-06-30T07:16:16] front_door_contact | BooleanState.StateValue = False

No occupancy detection in any room between 07:00 and 07:19

Contact local law enforcement immediately to file a report regarding unauthorized entry.

Review camera footage (if available) specifically around 07:16 to identify the method of entry.

Check the interior of the home for signs of disturbance, theft, or damage.

Temporarily disable automatic re-locking features on the front door until security protocols are reviewed.

A forced entry attempt occurred at the front door while residents were asleep inside, evidenced by a sensor-triggered auto-lock event immediately following an open door contact state.

Explanation: At 22:46:16, the front door contact sensor reported 'True' (Door Open) while occupancy sensors in bedrooms indicated residents were present and sleeping.

Explanation: Two seconds later at 22:46:17, the lock triggered an automatic operation ('Auto') to engage, which is consistent with a security system reacting to a breach or forced entry rather than manual user interaction.

Explanation: The sequence of Door Open -> Auto Lock within a 1-second window during nighttime hours strongly indicates an intrusion attempt that was detected by the smart home system before full access could be gained.

[2026-06-19T22:46:10] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

Immediately contact local law enforcement to report the attempted break-in.

Check all entry points (windows/doors) for signs of forced entry or tampering.

Review camera footage from the time of the event (22:45–22:48) to identify the intruder or method used.

Temporarily disable 'Auto' re-locking features until the source of the trigger is verified to prevent future false alarms or missed detections.

Check if any motion sensors triggered in Entrance, Living Room, or Hallways between 22:30 and 22:50.

Verify camera footage for the front door around 22:46 to see who approached or touched the handle.

Inspect the 'front_door_lock' raw binary logs to confirm if 'Auto' source corresponds to a smart lock mechanism or a keypad entry logged incorrectly.

Cross-reference with network logs to see if there was an external command sent to the door lock from an IP outside the trusted home network.

Explanation: Occupancy sensors show clear presence/absence patterns matching human activity (e.g., presence at 07:28 after morning exit, absence overnight, return at 16:22).

Explanation: The 'Auto' lock operations (LockOperationType=0) are immediately preceded by contact sensor events showing the door was closed (StateValue changed from False to True), confirming normal operation rather than a forced entry or malfunction.

Explanation: There is no evidence of the house being vacant while doors were left unlocked; occupancy data confirms residents were present during all manual lock/unlock sequences.

The observed lock state toggling is a confirmed automated geofence exit routine initiated by the homeowner's departure, supported by consistent occupancy and contact sensor data.

Explanation: The front door was manually locked at 07:44:28, immediately followed by the door contact sensor opening (False) at 07:44:30, indicating the resident left.

Explanation: The auto-unlock event at 07:44:39 occurred 9 seconds after the door opened, which aligns with a standard 'Geofence Exit' automation rule rather than an unauthorized intrusion.

Explanation: Later events (22:42) show the reverse pattern: door closed, then automatically unlocked upon arrival, confirming the system logic functions correctly as designed.

Verify if any other doors or windows were manipulated around 07:44:28.

Cross-reference camera footage (if available) or smart home hub logs for any command origin IP addresses during the 07:44:28 auto-unlock event.

Confirm if the 'Auto' source at 07:44:39 corresponds to a scheduled automation rule (e.g., geofence exit) or an unsolicited trigger.

The system exhibits a benign sensor glitch (false unlock) followed by immediate manual correction, consistent with a door frame misalignment or momentary sensor noise rather than an intrusion.

Explanation: Raw log confirms the front door was physically locked at 07:43:23 and manually re-locked at 15:57 and 17:50, proving user control and no forced entry.

Explanation: The 'unlocked' state at 07:43:27 was immediately reverted to 'locked' by a subsequent manual lock operation minutes later, indicating it was likely an automation error triggered by a transient sensor signal (e.g., door ajar for <2 seconds).

Explanation: No unauthorized occupancy events were detected; all motion triggers correspond to expected household activity patterns, and the house is confirmed empty at night.

Explanation: Temperature readings show normal fluctuation without signs of overheating or fire risk.

High count of salient events (60) and focus events (89) suggests significant system activity, not just isolated glitches.

Multiple successful manual locks later in the day (15:57, 17:50) confirm the user can override or correct the system state manually.

Household members are present during the day (activity peaks) and absent at night.

Room activity counts show high activity in Entrance (20), Living Room (16), and Kids Room (12) during waking hours.

Zero occupancy readings at 00:00 across all monitored zones confirm the house is currently unoccupied.

Window coverings are fully closed (10000) in bedrooms and living areas around 22:18, consistent with nighttime preparation.

Door contact sensor status immediately preceding and following the 07:43:23 and 07:43:27 timestamps to determine if the physical door actually cycled.

Motion sensor triggers in the entrance hallway between 07:43:23 and 07:43:27 to rule out someone passing through without triggering the primary motion sensor.

Timestamp ordering verification for the 22:18:19 (Unlock) vs 22:18:29 (Lock) sequence to resolve potential clock skew or logging artifact.

An intruder likely gained entry via the front door during a confirmed period of total house vacancy, unlocked it manually to exit or re-enter, and subsequently triggered occupancy sensors.

Explanation: House was confirmed empty (occupancy=0) in all rooms from midnight until 07:08.

Explanation: At 07:07:08, the front door lock was operated manually (Source=Manual) while no occupant was detected inside.

Explanation: Immediately following this manual operation, the door contact sensor state changed from Closed (True) to Open (False) at 07:07:10, proving physical access occurred without an authorized resident present.

Explanation: Occupancy sensors only registered presence after the door event (Bedroom at 07:08, Kitchen at 08:26), confirming the timeline of unauthorized entry.

Contact local law enforcement immediately with the timestamped evidence of forced/unauthorized entry.

Change all smart home credentials, Wi-Fi passwords, and physical keys associated with the residence.

Inspect the perimeter for signs of forced entry and secure the property before police arrival.

Possible forced entry attempt via the bedroom window or internal movement after external access.

Repeated toggling of bedroom window coverings to fully open (0) and closed (10000) positions, particularly at 13:54 and 20:42.

High frequency of 'suspicious_signals' (60 salient events) compared to normal baseline expectations for a single resident.

No direct evidence of window contact sensor triggering in the provided log snippet (only window covering position reported).

Front door manual unlock (Type=1) at 07:07:08 immediately followed by state change to unlocked (1) while all room occupancy sensors report '0' (empty).

Confirmed total house vacancy at midnight (00:00:00 - 00:30:00) across all monitored rooms.

Frequent manipulation of bedroom window coverings (open/close cycles) without corresponding motion detection data in the provided snippet.

Timestamped logs for the front door contact sensor (contact_sensor) to confirm if the door was physically opened/closed during the 07:07:08 event.

Raw video footage or camera feeds from the entrance hallway and bedroom windows around 07:07 and 13:54.

Detailed operation source logs for the front door lock to verify if 'Auto' sources are legitimate smart-home automation rules or spoofed commands.

Motion sensor logs specifically filtering for 'intrusion' vs 'pet/noise' false positives around the midnight vacancy timestamps.

Evidence strongly suggests an intruder entered the home early in the morning via a bedroom window, remained undetected by occupancy sensors due to likely sensor failure or calibration drift, and exited manually unlocking the front door.

Explanation: Occupancy sensors reported '0' (empty) across all rooms from midnight until 06:57, despite timestamps showing light being turned on and a window opened at 05:27, indicating a critical sensor malfunction or blind spot that prevented detection of the intruder.

Explanation: The sequence of events—bedroom light turning on (05:27), window fully opening (05:28), followed by front door manual unlock (06:57) and immediate auto-relock—indicates someone accessed the interior through the window and later left through the door.

Explanation: Temperature logs show a steady rise consistent with HVAC operation or lack of cooling when unattended, but the primary anomaly is the discrepancy between the physical actions (window open, light on) and the digital absence of occupancy signals.

[2026-06-09T05:27:04] bedroom_light | OnOff.OnOff = True

Immediately contact law enforcement to file a report regarding suspected unauthorized entry.

Change all access codes and locks immediately after police clearance.

Investigate the bedroom occupancy sensor for malfunction or obstruction causing false negatives during the incident timeframe.

Early morning (05:27) bedroom window fully opened (0%) while no occupancy detected.

Front door manually unlocked at 06:57 shortly after the window incident.

Complete lack of occupancy signals across all monitored zones between midnight and early morning.

Motion detection logs specifically around 05:27 to confirm if any movement occurred in the bedroom or hallway despite the '0' occupancy reading.

Camera footage (if available) or smart doorbell logs for the timeframe 05:27 - 07:00 to verify who entered/exited.

Heartbeat sensor data or bed-sensor logs to determine if the resident was actually asleep or absent during the night.

Evidence indicates a potential forced entry attempt at 06:53 where the door was manually locked from the outside while the occupant was inside, followed by immediate auto-locking and contact closure.

Explanation: At 06:53:09, the front door lock state changed to 'Locked' (State=2) via Manual operation. Crucially, the door contact sensor remained open (False/Unlocked) until 06:53:11, suggesting the door was physically closed or manipulated against resistance without triggering an immediate 'open' signal, or the manual override bypassed normal sequencing.

Explanation: Exactly 3 seconds later at 06:53:12, the system triggered an Auto-lock (State=1), which is inconsistent with standard user behavior of locking after entering; this sequence suggests an external actor may have engaged the lock mechanism before the internal occupant could react or exit.

Explanation: Immediately following the second lock event at 06:53:12, the entrance occupancy sensor registered presence (Occupancy=1). This confirms someone was inside the house during the anomalous locking sequence, supporting the theory that the resident was locked in rather than having simply left.

[2026-06-22T06:53:11] front_door_contact | BooleanState.StateValue = False

[2026-06-22T06:53:12] entrance_occupancy | OccupancySensing.Occupancy = 1

Contact local law enforcement immediately to report a suspected break-in/burglary attempt.

Check the front door handle, frame, and surrounding area for signs of tampering or forced entry damage.

Review smart home camera footage specifically around 06:53 to identify if any movement occurred outside prior to the manual lock command.

The system confirms normal resident activity with no evidence of intrusion; the auto-unlock events were triggered by legitimate proximity sensors upon resident return.

Explanation: Analysis of the 07:08 sequence shows the front door contact sensor (BooleanState) toggled from False to True exactly between the manual lock and auto-unlock events, confirming a person physically opened the door to enter the house, triggering the expected 'Auto' unlock feature.

Explanation: The 20:43 sequence similarly shows the door contact activating at 20:43:13 immediately preceding the auto-unlock at 20:43:14, followed by bedroom lights turning on and the window opening, which aligns perfectly with a resident returning home and securing the perimeter via automated routines.

Explanation: All occupancy logs show consistent patterns of residents entering specific rooms (bedroom, living room) coinciding with device activations, ruling out unauthorized access or forced entry scenarios described in the initial hypotheses.

[2026-06-20T07:08:08] front_door_contact | BooleanState.StateValue = False -> [2026-06-20T07:08:13] front_door_contact | BooleanState.StateValue = True

[2026-06-20T20:43:13] front_door_contact | BooleanState.StateValue = True -> [2026-06-20T20:43:14] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Standard automated morning routine: The system logs show multiple rooms reporting occupancy as '0' at 00:00 and 00:30. Given the 'Elderly Living Alone' layout, this likely indicates the house was empty overnight, which is normal.

[2026-06-20T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

[2026-06-20T00:30:00] kitchen_occupancy | OccupancySensing.Occupancy = 0

Check for proximity sensor data near the front door between 07:08:06 and 07:08:14 to determine if a person was physically present triggering an automatic unlock.

Verify the timestamp accuracy of the front door lock events vs. the bedroom window opening event to rule out clock skew causing false correlations.

Cross-reference with motion sensor logs in the entrance hallway to see if someone entered/ exited during the 07:08 manual lock/unlock cycle.

The sequence of events indicates a resident leaving the house in the morning and returning to adjust curtains before going back out; no unauthorized entry or safety threat is detected.

Explanation: Occupancy logs confirm the resident was present in the bedroom at 14:06 when the window opened (State=1), ruling out an intruder accessing an empty room.

Explanation: The door lock state transitions (Manual Lock -> Door Open/Contact False -> Auto Unlock) followed by re-locking are consistent with normal exit and return routines observed earlier in the day (07:00).

Explanation: The window position changing from closed (0) to open (10000) at 20:44 after lights turned on suggests a deliberate human action (opening curtains) rather than forced intrusion.

[2026-06-23T14:06:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

Continue standard monitoring; no immediate intervention required.

Verify that the window locking mechanism is functional once fully opened if this is a security concern for future nights.

Regular timestamps suggesting daily routines.

The specific sequence of DoorState=2 (Open?) at 08:28 followed immediately by a Window opening at 14:06 without intervening human activity logs creates an inconsistent narrative for a standard routine.

Door manually locked at 08:28 (State 2) followed by Bedroom Window fully opened (0%) at 14:06.

Discrepancy between Manual Lock operation and subsequent lack of Auto-unlock or Motion confirmation in the timeframe.

Single point of entry vulnerability: Elderly resident alone, window opened mid-day without clear context of occupant location.

Check `bedroom_occupancy` raw logs specifically between 14:00 and 15:00 to see if any motion was detected when the window was opened.

Verify `front_door_lock` raw logs to confirm if State 2 corresponds to 'Locked' or 'Unlocked' (context dependent on vendor schema, usually 0=Locked, 1=Unlocked, or vice versa; here 2 might mean 'Just Unlocked' or 'Unlocked').

Review `living_room_motion` and `kitchen_motion` logs around 14:06 to rule out the resident moving rooms before opening the window.

Evidence strongly indicates a forced entry or intrusion attempt at the front door, characterized by an immediate re-locking after a manual lock event, followed by the resident entering.

Explanation: At 07:07:06, the front door was manually locked (State=2), indicating the system believed it was secured.

Explanation: Immediately following this, at 07:07:16, the door contact sensor detected the door opening (State=False) and closing again (State=True) within 10 seconds, despite no subsequent 'unlock' operation command being logged until 07:07:17.

Explanation: At 07:07:17, the lock automatically transitioned to State=1 (Unlocked), suggesting the system registered the door as open/forced and auto-responded to secure the interior or mark the breach. The sequence of Manual Lock -> Immediate Physical Breach/Auto-Cycle -> Auto-Unlock is highly atypical for normal behavior.

Explanation: Occupancy data confirms the resident entered the bedroom shortly after (07:08:00), consistent with someone responding to a security incident rather than a routine morning routine which would typically show earlier activity.

[2026-06-02T07:07:08] front_door_contact | BooleanState.StateValue = False

[2026-06-02T07:07:16] front_door_contact | BooleanState.StateValue = True

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

Change all locks on the front door and any other external access points immediately.

Review available camera footage (if any) specifically between 07:07:00 and 07:10:00 to identify the intruder.

Check the physical condition of the front door frame and lock mechanism for signs of tampering or forced entry tools.

The home security system was compromised at night, indicated by an automatic door unlock followed immediately by the opening of a bedroom window while the house was unoccupied.

Explanation: At 20:36:12, the front door lock state changed to unlocked (LockState=1) via an 'Auto' source, despite zero occupancy in all rooms including the entrance since midnight.

Explanation: Exactly three seconds later at 20:36:18, the bedroom window covering opened fully (100%), suggesting an automated response to a triggered sensor or manual tampering inside.

Explanation: The sequence of events (Door Unlock -> Window Open) occurring without any human presence detected strongly indicates a forced entry or a sophisticated intrusion attempt rather than routine automation.

Contact local law enforcement immediately to report a potential burglary.

Review security camera footage from the front door and bedroom between 20:30 and 20:45 if available.

Temporarily disable all remote 'Auto' unlock features until the system is physically inspected and verified secure.

Review camera feeds (if available) for the entrance and bedroom during the 20:30–21:00 window.

No security breach or safety threat detected; observed events are consistent with a resident performing normal daily activities while the occupancy sensor suffered from delayed calibration during early morning hours.

Explanation: The 'manual unlock' at 07:07:04 was immediately followed by an 'auto lock' event (LockOperationType=0) within seconds, and the door contact sensor confirmed the door closed and locked, ruling out an unattended open state or intrusion.

Explanation: Occupancy sensors reported '0' for several hours but switched to '1' shortly after the light and window interactions began (e.g., kitchen at 08:25, bedroom at 08:26), indicating the sensors simply lagged behind actual presence rather than detecting an empty house.

Explanation: The rapid toggling of curtains corresponds exactly with light activation/deactivation times and matches the subsequent occupancy detection, confirming these were actions taken by a present resident to adjust lighting/privacy, not an intruder checking escape routes.

[2026-06-03T08:26:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

Review motion sensor calibration logs to investigate why occupancy was not detected until 30+ minutes after residents entered rooms in the morning.

No immediate physical intervention required as the home is currently secure and occupied.

Elderly resident safety risk due to prolonged isolation and potential inability to interact with devices. All room occupancy sensors reported zero occupancy for extended periods starting from midnight, yet there are significant device interactions (door locks, curtains) occurring later in the day, implying the resident may be incapacitated or unaware of the security system status.

Evidence of active device manipulation (curtains, doors) suggests *someone* is present or controlling them remotely.

Front door manual unlock at 07:07:04 followed by immediate lock state change without a recorded manual lock operation.

Repetitive rapid toggling of bedroom window coverings between fully closed and fully open states during daylight hours.

Persistent 'No Occupancy' readings across all rooms since midnight despite evidence of activity within the house.

Check raw video feed or audio logs from the entrance and bedroom around 07:07:04 and 12:33:17 to confirm if a person entered or manipulated the curtains.

Verify the specific definition of 'LockOperationType' codes (0 vs 1) and check for any missed 'Unlock' events that might have been filtered out by the preprocessing logic.

Inspect motion sensor calibration logs and sensitivity settings to determine why occupancy was not detected despite physical activity (e.g., movement near blinds but not floor level).

Check if the 'Auto' source for the 20:43:13 lock event was triggered by a sensor delay or a scheduled routine rather than the actual closing of the door.
