The observed window covering movement corresponds to standard automated arming routines and resident activity, with no evidence of physical intrusion.

Explanation: Occupancy sensors confirm the house was empty during the night (00:00-06:37) and residents returned at 06:37, matching a normal sleep/wake cycle.

Explanation: The bedroom window cover change at 21:48 occurred simultaneously with the front door auto-locking event, indicating an automated 'goodnight' routine rather than an intruder opening a window while the main door was locked.

Explanation: No breach events or contradictory sensor readings (e.g., open contact sensors) were found in the raw logs around the suspicious timestamps.

Continue monitoring; no immediate action required.

Verify smart-home automation schedules to ensure window covering retraction is intentionally linked to the security arm sequence.

Event count (1125) vs Salient (60) ratio suggests many low-level noise events or log spam, which can occur if sensors are misconfigured

Room activity metrics might simply reflect background device chatter (thermostats, timers) rather than human presence

The clear temporal correlation of door locking events with specific times (morning/evening) supports a logical schedule over random chaos

Check the raw `bedroom_contact_sensor` logs around T21:48:35 to confirm if the window pane itself was breached or if it remains physically closed while curtains moved.

Verify the source of the `WindowCovering` actuation commands at 06:37 and 21:48 to distinguish between user control, smart-home automation schedules, and unauthorized local triggers.

Review `living_room_occupancy` and `bedroom_occupancy` logs prior to 00:00 to determine when residents actually vacated the premises, ensuring the 'empty house' assumption holds true for the entire duration of the reported zero-occupancy period.

High probability of an intruder entering the home via the bedroom window and immediately exiting through the front door before security was fully armed.

Explanation: Occupancy sensor in the bedroom triggered at 23:11:07, exactly 10 seconds before the window cover command executed at 23:11:17, indicating a person was present when the window was opened.

Explanation: The front door contact sensor tripped (Door Open) at 23:11:21, followed immediately by an 'Auto' lock command at 23:11:22; this sequence suggests a rapid entry-exit event where the occupant or intruder left just as the system attempted to secure itself.

Explanation: No other motion sensors were triggered between the bedroom event and the front door event, suggesting the individual moved quickly from the bedroom directly to the exit without being detected in intermediate zones.

[2026-06-14T23:11:22] front_door_lock | Event: LockOperation(... OperationSource=Auto)

Immediately contact local law enforcement to report a potential burglary attempt.

Inspect the bedroom window area for signs of forced entry or footprints.

Review front door camera footage if available to confirm the identity of the person who exited.

Lock operation source listed as 'Auto' but coinciding with a physical breach indicator (open window) suggests either a failed automation logic or a reactive lock upon detection of intrusion (which usually requires a sensor trigger not seen here).

Temporal coincidence: Bedroom window fully opened (23:11:17) immediately preceding Front Door Locking (23:11:22).

Absence of occupancy data contradicting the presence of an intruder moving through the house while windows are open.

Lock operation source 'Auto' occurring without explicit motion or contact sensor alarms in the evidence packet.

Timestamps and state changes for all Occupancy Sensors (living_room, bedroom, bathroom) specifically between 23:11:00 and 23:12:00.

Contact Sensor logs for 'bedroom_window' to confirm if it detected an opening/closing event distinct from the covering motor command.

Full audit trail for the 'front_door_lock' to determine the exact mechanism of the 'Auto' lock command (e.g., was it triggered by a zone alarm, manual override, or system error?).

Temperature and Smoke Alarm logs around 23:11 to rule out environmental anomalies causing false sensor readings.

High probability of burglary attempt: Front door was automatically unlocked while all rooms were empty, followed immediately by a sensor indicating the door was open.

Explanation: Occupancy sensors reported '0' (empty) in living room, bedroom, and bathroom starting at 00:00:00.

Explanation: At 22:04:34, the front door lock changed to 'unlocked' (State=1) via 'Auto' source while the house was confirmed empty.

Explanation: Immediately following the unlock at 22:04:34, the front door contact sensor triggered an 'open' state (True) at 22:04:33 (likely a timestamp alignment issue or rapid transition), confirming the door was not just unlocked but opened.

Explanation: No subsequent occupancy reports suggest no one entered yet, but the breach of the perimeter is established.

No security anomaly detected; logs confirm consistent occupancy zero during the night and a secure locking sequence upon waking.

Explanation: Occupancy sensors reported '0' for all rooms (living_room, bedroom, bathroom, kitchen) continuously from 00:00 until 06:35.

Explanation: No door unlock events or forced contact triggers were recorded between the previous evening's lockout (22:03) and the morning manual lock (07:38).

Explanation: The house was secured properly at 07:38 with both manual and auto-lock operations confirmed by state transitions to 'Locked'.

All occupancy sensors show Occupancy = 0 throughout the overnight period (00:00 - 06:35).

Front door log shows Event: LockOperation(LockOperationType=1, OperationSource=Manual) followed by Auto-lock at 07:38:24.

No 'LockOperationType=2' (Unlock) events or unexpected BooleanState changes on front_door_contact occurred after 22:03.

Verify that temperature readings (rising from ~22°C to ~25°C) align with HVAC settings rather than indicating an appliance fault.

Check raw logs for any 'DoorLock.LockState' transition to 'Unlocked' (typically state 3 or similar depending on schema) between 22:03 and 06:38.

Verify if the 'room_activity' counts correspond to specific timestamps or are cumulative daily stats; if timestamps exist, check what actions occurred in the kitchen/living room before 00:00.

Cross-reference the 'bedroom_window' opening event (22:03:45) with the front door lock state to ensure the window was not opened while the house was considered 'empty' (no occupants in bedroom).

The house is secure; all observed events correspond to normal resident behavior with no signs of intrusion or system failure.

Explanation: Occupancy logs confirm residents were present in the bedroom and bathroom around 06:26, explaining why the window was manually closed before the door was unlocked later.

Explanation: Door contact sensors show a clear sequence at 07:14 where the door opened (False) then closed (True) immediately after manual unlocking, consistent with a resident entering.

Explanation: The evening window opening at 21:46 occurred seconds before the front door auto-locked, matching the pattern of a resident exiting through the bedroom and leaving via the front door.

An intruder likely entered the home between 23:15 and 00:30, manipulating window coverings and triggering a door sensor before the automated locking sequence occurred.

Explanation: Raw logs show bedroom occupancy changing to '1' at 23:15:05, immediately followed by the window covering command (10000) at 23:15:08, indicating human presence and manual interaction inside the house.

Explanation: The front_door_contact sensor triggered (StateValue=True) at 23:15:12, just seconds before the auto-lock event, proving the door was physically opened/closed by an external force rather than a glitch.

Explanation: Occupancy sensors in all rooms remained at '0' until 08:28, creating a false negative that masked the intrusion during the critical night hours.

[2026-06-06T23:15:12] front_door_contact | BooleanState.StateValue = True

Contact local authorities to file a police report regarding the break-in.

Change the access codes and physical locks on all entry points immediately.

Review security camera footage if available to identify the intruder's appearance or method of entry.

Timestamps of window cover changes and door locking occurring simultaneously (within seconds) suggest coordinated action rather than independent automation.

Check raw logs for 'front_door_contact' state changes around 00:30 to confirm if the door was opened/closed physically during the reported empty occupancy period.

Verify if 'WindowCovering' value '10000' corresponds to a specific motor command or a sensor glitch/failure reading.

Cross-reference 'room_activity' counts with motion sensor data to determine if the high activity in Kitchen/Living Room is from pets, insects, or actual undetected humans.

Inspect logs between 23:15:08 and 00:30:00 for any other contact sensor triggers on windows or doors.

An intruder likely entered the empty house via the front door at 23:07, triggering an automated lock cycle before being detected by occupancy sensors at 23:09.

Explanation: Occupancy sensors reported '0' (empty) for all rooms from 00:00 to 10:09, confirming the home was unoccupied during the incident window.

Explanation: At 23:07:23, the front door contact sensor state changed to True (open), indicating a door was physically breached or opened.

Explanation: Immediately following the opening, a LockOperation event occurred at 23:07:24 with Source='Auto', suggesting the system attempted to re-lock after detecting the breach or as part of a forced entry sequence.

Explanation: The timeline ends abruptly at 23:09:00 when occupancy becomes 1, consistent with an intruder entering and triggering motion/occupancy detection rather than a homeowner returning.

No security breach detected; the manual lock at 18:27 coincided with an open door (contact sensor active), indicating a user error or temporary access event rather than unauthorized entry.

Explanation: The occupancy logs confirm residents were present in the home between 18:25 and 21:48 (bedroom light on at 21:48, occupancy active earlier).

Explanation: At 18:27, the front door was manually locked while the contact sensor simultaneously registered as 'False' (open), suggesting the door was not fully closed before locking or was held open momentarily by an occupant.

Explanation: The subsequent auto-unlock at 21:48 occurred immediately after the bedroom window was closed (transition from 0% to 100%), consistent with a resident returning from outside to secure the home for the night.

Explanation: Temperature data shows a steady rise throughout the day typical of ambient heating, with no anomalies like rapid spikes indicative of fire or malfunction.

[2026-06-10T18:27:00] front_door_contact | BooleanState.StateValue = False

Check access logs for front_door_lock at 21:48 to confirm if a physical key was used vs. smart lock auto-unlock command.

Verify if the 'Auto' source for the unlock at 21:48 corresponds to a scheduled routine or an external trigger (e.g., motion sensor).

Cross-reference kitchen and living room activity logs between 18:27 and 21:48 to determine if occupants were present when the door was manually locked later that evening.

An unauthorized entry attempt was detected where the front door was manually unlocked from the outside, remained open for approximately 7 seconds while occupancy sensors registered a presence inside, before being auto-locked.

Explanation: The log shows a 'LockOperation' with source 'Manual' at 07:27:18 changing the state to locked (2), which is inconsistent with standard departure behavior if residents were already inside closing the door.

Explanation: Critically, at 07:27:20, the door contact sensor reports 'StateValue = False' (open), followed immediately by 'StateValue = True' (closed) at 07:27:24, creating a 4-second window where the door was physically open.

Explanation: During this specific window (07:27:20 - 07:27:24), the bedroom occupancy sensor reported 'Occupancy = 1', indicating a person was present inside while the door was ajar after an external manual unlock event.

[2026-06-18T07:27:20] bedroom_occupancy | OccupancySensing.Occupancy = 1

Immediately review security camera footage of the front entrance between 07:27:15 and 07:27:30 to identify the individual who manually unlocked the door.

Change all access codes or smart lock credentials immediately as the device may have been compromised or bypassed.

Inspect the physical condition of the front door lock mechanism for signs of tampering or forced entry.

Standard daily routine: Residents locked the door manually upon leaving (07:27 AM) and later unlocked it automatically (likely returning home) at 22:03 PM, which aligns with the window curtains opening at the exact same time.

Timestamp precision between the 'LockOperation' event source and the actual 'LockState' transition to ensure the door was not left ajar for an extended period.

Check if the 'OperationSource=Auto' at 07:27:25 corresponds to a motion sensor trigger inside the house (indicating return) or if it was a system glitch.

Verify if there are any tamper alerts on the front door lock sensor between 07:27:18 and 07:27:25.

The door lock sequence represents a standard automated evening routine where the system locked the door immediately upon detecting the entrance zone was empty, confirming no unauthorized entry occurred.

Explanation: Occupancy logs show the house was unoccupied from midnight until 18:07, with no movement in the entrance hall at the time of the manual unlock (18:08).

Explanation: The contact sensor log shows the door opened briefly at 18:08 and closed by 18:08:02, but remained closed (True state) continuously until 22:32:20.

Explanation: The 'Auto' lock event at 22:32:21 corresponds exactly to the moment the occupancy sensor detected the final person leaving the master bedroom and the entrance zone becoming vacant, triggering a scheduled security rule.

Explanation: There is zero evidence of tailgating or intrusion; the door was physically secured while the home was empty.

[2026-06-10T15:57:00] front_door_lock | DoorLock.LockState = 2

Manual front door unlock at 18:08 followed by a state change to Open, yet zero occupancy detected in the entrance zone afterward until midnight.

The 'Auto' lock operation at 22:32:21 occurred exactly 4 minutes after the master bedroom window cover was reported as 100% closed, but the door had been open since 18:08.

Check the `entrance_contact_sensor` log between 18:08:00 and 22:32:21 to confirm if the door remained physically open or if it was briefly opened/closed multiple times.

Verify the timestamp of the `front_door_lock` opening event vs. the closing event to see if there was a gap where the door was left unlocked while the house was unoccupied.

Cross-reference the `master_bedroom_window_covering` actuation time (22:32:13) with the `living_room_occupancy` logs to determine if residents were present in other rooms when the window was closed.

Potential intruder accessed the master bedroom and opened curtains while the house appeared empty based on occupancy logs, coinciding with an automated front door unlock.

Explanation: Occupancy sensors confirmed residents were away from the house at 22:12 (all rooms showed Occupancy=0 until 22:12:07 when only the master bedroom was occupied).

Explanation: At 22:12:07, the master bedroom occupancy changed to 1, followed immediately by the window coverings fully opening at 22:12:12, suggesting an actor inside the room.

Explanation: Simultaneously, the front door contact sensor reported 'True' (closed) just before an 'Auto' source triggered an unlock event at 22:12:22, which contradicts normal resident behavior patterns seen earlier in the day (e.g., manual unlocks upon arrival/departure).

Immediately review security camera footage of the entrance hallway and master bedroom for the time range 22:12:00 to 22:13:00 to identify the individual.

Contact local law enforcement or property management if surveillance confirms unauthorized access.

Sequence of manual unlock (07:46, 16:09, 17:51) followed by an Auto-unlock (22:12) immediately preceding a Master Bedroom curtain opening.

Door state transition to UNLOCKED (State=1) at 22:12:22 coincides with high-risk activities (curtain opening).

Check raw motion sensor logs for master_bedroom between 22:12:00 and 22:13:00 to confirm if anyone entered the room.

Verify the definition of LockOperationType=0 vs Type=1 to ensure 'Auto' unlock isn't a false positive for a forced entry attempt.

Review camera feeds or secondary sensor logs for the entrance hallway around 22:12 to see who/what triggered the door state change.

Check if the master bedroom window sensor (contact_sensor) was triggered when the curtains were opened.

An intruder likely entered the home by unlocking the front door at 22:24 immediately after opening the master bedroom window, exploiting a sequence where occupants were not present to operate the window manually.

Explanation: Occupancy sensors confirmed 0 occupants in all rooms (including entrance) prior to the event, ruling out normal residents operating the window or door.

Explanation: The temporal sequence shows the window state changed to fully open (100%) at 22:24:15, followed 9 seconds later by an automatic door unlock at 22:24:24.

Explanation: The combination of an unattended window opening and subsequent door access indicates a coordinated entry attempt rather than a single automated routine like 'Good Night', as residents are absent.

No security anomalies detected; observed events are consistent with a standard departure and return routine, including a likely sensor glitch during the morning exit.

Explanation: The morning sequence (07:12) shows manual locking followed by contact sensor opening (False), then closing (True), which confirms the door was physically closed before the auto-unlock event, ruling out an intrusion or tailgating attempt.

Explanation: The late-night event (22:10) involves the front door being auto-locked immediately after the contact sensor indicated it was already closed (True at 22:10:33), suggesting the system correctly secured an occupied room rather than detecting an intruder.

Explanation: Room occupancy logs confirm residents were present in the master bedroom during both the morning departure window and the late-night incident, supporting normal household activity over unauthorized entry.

[2026-06-25T22:10:33] front_door_contact | BooleanState.StateValue = True

Review firmware for the front_door_lock controller to investigate the discrepancy between manual lock engagement and subsequent auto-disengagement logic.

Verify if the master_bedroom_window covering motor requires calibration or if the 'fully open' state is a scheduled automation.

[2026-06-25T16:26:00] front_door_lock | DoorLock.LockState = 2

Residents left the house during the early morning (07:12) and returned later in the day (16:26), consistent with a standard workday schedule.

Front door locked manually at 07:12:19 then auto-unlocked at 07:12:27 (leaving).

Front door locked manually at 16:26:00 (returning).

High room activity counts in kitchen, living_room, and entrance during these periods.

Rapid toggle between Manual Lock and Auto Unlock at 07:12:19 and 07:12:27 (potential bypass or glitch).

Master bedroom window covering fully opened at 22:10:24, coinciding with late-night manual door locking.

Timestamps and status codes for 'front_door_contact' sensor around 07:12 to verify if the door was actually opened/closed vs just the lock mechanism toggling.

History of 'master_bedroom_window' contact sensor state changes around 22:10 to see if the window was physically touched or opened.

Camera feeds or motion detection logs for the hallway/entrance area between 07:12:27 and 07:12:30 to rule out a second person entering immediately after the owner 'left'.

System logs for any firmware updates or known bugs related to the front_door_lock controller on 2026-06-25.

The auto-lock event at 23:13 was triggered by the home's 'Away Mode' automation (likely via door contact closure) while the house remained unoccupied and secure.

Explanation: Occupancy sensors confirmed zero presence in all rooms (including entrance) from 00:00 through 05:30, ruling out an intruder inside during the suspicious window.

Explanation: The 'OperationSource=Auto' combined with the preceding front_door_contact state change indicates a scheduled automation or motion-triggered lock cycle typical of Away Mode, rather than manual user interaction or forced entry.

Explanation: No subsequent motion events or tamper alerts were recorded after the lock engaged, consistent with a successful automated security routine.

Two distinct manual lock-to-unlock transitions occurred at 16:15 and 17:45 while all interior occupancy sensors remained at zero, strongly indicating unauthorized entry or tampering.

Explanation: Occupancy sensors for master_bedroom, living_room, and other areas consistently reported '0' (empty) during the entire window between 16:14 and 17:45.

Explanation: Despite the house being empty, the front door lock state changed from Locked (1) to Unlocked (2) twice via manual operations at 16:15:00 and 17:45:00.

Explanation: The lack of any resident presence combined with manual manipulation of the lock mechanism suggests an intruder entered the property and locked/unlocked the door, rather than a resident moving in and out.

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

Check surveillance camera footage specifically for the timeframes 16:15 and 17:45 to identify the individual at the entrance.

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

[2026-06-24T07:23:11] front_door_lock | DoorLock.LockState = 2

The presence of 'manual' lock operations during hours when occupancy sensors show no activity could indicate an intruder manipulating the lock or a false positive from a glitched sensor.

Check camera footage (if available) for the entrance hallway at 16:15 and 17:45 to see who operated the door.

Verify the state of the contact sensor (<contact_sensor>) associated with the front_door_lock immediately before and after these manual lock events to confirm if the door was actually opened/closed.

Cross-reference the 'room_activity' counts for kitchen, living_room, and bedrooms around 16:00-18:00 to definitively rule out resident movement during that window.
