The front door lock exhibits a critical state conflict where a manual lock operation (State=2) was immediately overridden by an auto-unlock, followed later by a manual lock attempt while the system still reported the door as locked, indicating firmware or sensor synchronization failure rather than human tampering.

Explanation: At 06:50:08, a manual lock command set the state to 'Locked' (2), but exactly 6 seconds later at 06:50:14, an 'Auto' unlock command reverted it to 'Unlocked' (1) without any corresponding motion sensor trigger in the raw logs.

Explanation: At 08:22:00, another manual lock command was issued, yet the log explicitly records 'DoorLock.LockState = 2' again. However, shortly after at 20:36, the door is automatically unlocked again, suggesting the 'Locked' state at 08:22 may have been a transient glitch or misreport that wasn't resolved until the final auto-cycle.

Explanation: Crucially, the bedroom window manipulation (H2) shows perfect temporal correlation with occupancy sensors (Bedroom occupied at 12:25 -> Window Open; Kitchen occupied at 13:53 -> Window Closed), confirming normal user behavior and contradicting the hypothesis of intrusion or testing.

[2026-06-19T06:50:08] ... LockOperationType=1 ... DoorLock.LockState = 2

[2026-06-19T06:50:14] ... LockOperationType=0 ... OperationSource=Auto

[2026-06-19T08:22:00] ... LockOperationType=1 ... DoorLock.LockState = 2

Manually verify the physical status of the front door lock mechanism to ensure it is not stuck or broken.

Update the smart-lock firmware to resolve the State=2 conflict bug and disconnect the automatic unlock feature temporarily for security.

Routine morning/night routine involving door locking/unlocking and curtain adjustments, consistent with an elderly person managing their home environment.

Room activity distribution shows moderate usage across kitchen, living room, and entrance

Rapid toggle of window coverings within minutes (e.g., 12:25 to 13:53 is plausible for cleaning but the sequence 0->10000->0 is erratic given no occupancy changes reported immediately before/after in the snippet), immediate auto-unlock following manual lock

Front door lock state transition from Manual Lock -> Auto Unlock -> Manual Lock (while state indicates locked) within 2 hours.

Bedroom window coverings toggling rapidly between closed and fully open multiple times without clear occupancy context.

Timestamps and duration of all front_door_lock operations to determine if the 'Auto' unlock at 06:54 was a legitimate sensor-triggered event or a system glitch.

Motion sensor logs for bedroom_occupancy around 12:25 and 13:53 to verify if anyone entered the room when curtains were manipulated.

Access control logs to see if any failed authentication attempts occurred prior to the manual locks at 06:50 and 08:22.

System log entries for the smart-lock firmware version and known bugs regarding State=2 conflicts.

The observed pattern is a result of sensor calibration artifacts and periodic re-scanning rather than physical impossibility or intrusion; the door lock state change was an automated arming event following normal evening routines.

Explanation: The 'simultaneous occupancy' in multiple rooms (Entrance, Master, Kids, Dining) while Living Room/Second Bedroom are empty occurs repeatedly every ~20 minutes. This rigid, periodic repetition strongly indicates a sensor scanning loop or logic bug where the system reports status at fixed intervals rather than real-time human movement, as people do not physically teleport between these specific four rooms simultaneously while ignoring others for 15+ minutes.

Explanation: The temperature sensors in the Living Room and Kitchen show minor fluctuations but remain within reasonable environmental ranges, contradicting any fire risk or rapid heating anomaly that would accompany a large group gathering.

Explanation: The front door lock sequence at 22:44 follows a standard security routine: occupants retreat to bedrooms (Master occupancy detected), close curtains (WindowCovering=10000), the contact sensor detects the door closing (State=True), and the lock automatically arms (LockOperation=Auto, State=1). The 'Unlocked' state reported immediately after arming is likely a transient state update or the specific definition of 'armed/disarmed' cycle in this device's API, not evidence of unauthorized entry.

Explanation: No motion events, light switches, or window motor commands were triggered during the suspected 'intrusion' windows, further supporting the theory that the occupancy logs are static noise from a stuck or misconfigured sensor configuration.

Repeated identical occupancy patterns occurring every ~20-30 minutes (e.g., 11:57, 12:02, 12:07...) suggest an automated scan interval rather than organic human behavior.

Door contact sensor log shows `BooleanState.StateValue = True` (closed) immediately before the automatic lock command, confirming the door was secured by the resident system.

Absence of corresponding light switch changes or motion triggers in the raw logs for the occupied rooms during the multi-room detection windows.

Check sensor firmware/configuration for the Entrance, Master Bedroom, and Kids Room occupancy sensors to identify if they are set to 'fixed interval reporting' instead of event-based reporting.

Verify the sensor placement to ensure no two devices are triggering on each other's beams or detecting the same static heat source due to proximity.

Routine evening routine: Family members return home, settle into bedrooms/kitchen/dining for an activity session, then close up windows and secure the house from inside before going to sleep.

Sequential opening of curtains in specific rooms coinciding with the final unlocking of the front door

Standard occupancy flow into private rooms (Master/Kids) and service areas (Dining/Kitchen)

Manual locking of the front door during the day suggests normal resident behavior

The extremely rapid transition of occupancy across four rooms while two others remain empty could indicate sensor calibration issues or phantom triggers rather than physical presence

Simultaneous occupancy detection in Entrance, Master Bedroom, Kids Room, and Dining Room while Living Room and Second Bedroom are empty.

Front door manually locked twice during the day, but the state changed to 'Unlocked' (1) at 22:44:21 immediately after all bedroom curtains were confirmed closed (fully lowered/opened depending on logic, here 10000 likely means closed/full coverage).

Raw motion detection raw data (IR/PID values) for the Entrance, Master Bedroom, and Kids Room between 11:57 and 12:05 to rule out sensor cross-talk or dust interference.

Timestamps of light switches (dimming states) in the occupied rooms during the 11:57-12:05 window to confirm actual human movement vs. static sensor noise.

Door contact sensor logs for the Front Door to verify if the 'Unlocked' event at 22:44:21 was actually triggered by the door being opened, or just a sensor glitch/reset.

Window covering motor logs for Kids Room and Master Bedroom to verify if the '10000' position change was commanded by a user or an automation rule.

No confirmed anomaly; observed events are consistent with a resident returning home at 06:55 and subsequent normal activity.

Explanation: The 'Auto' unlock event at 06:55:07 is immediately preceded by the door contact sensor opening (entrance_occupancy=1) and kitchen occupancy rising, confirming a person physically entered before the system logged the auto-state change.

Explanation: The apparent conflict in H1 (Manual vs Auto timestamps) is resolved by the raw log showing the physical door state change coinciding with human presence, making the 'Auto' log likely a delayed status sync or routine cycle rather than a glitch masking an intrusion.

Explanation: Window cover toggling and other interactions occur only after occupants are detected inside, ruling out unattended manipulation during the alleged vacancy period.

[2026-06-24T06:55:07] entrance_occupancy | OccupancySensing.Occupancy = 1

[2026-06-24T06:55:04] kitchen_occupancy | OccupancySensing.Occupancy = 1

Monitor window covering behavior for future erratic patterns outside of occupied hours.

Review lock firmware logs to determine if the 'Auto' source indicates a scheduled routine or a delayed state report.

Extended period of total house vacancy combined with specific security events: All occupancy sensors report '0' across all rooms from midnight through early morning, yet there are active door/window interactions during this window.

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

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

[2026-06-24T00:30:00] kitchen_occupancy | OccupancySensing.Occupancy = 0

The presence of door lock operations and window cover adjustments implies someone was physically interacting with the home's systems.

Time-sequenced conflict between Manual and Auto lock/unlock events on the front door (06:55:04 vs 06:55:07).

Rapid oscillation of bedroom window coverings (Closed <-> Open) without sustained states, suggesting remote tampering or testing.

Discrepancy between 'Empty Home' occupancy readings and active physical interaction logs (door/window).

Check if the 'Auto' lock operation at 06:55:07 actually triggered a state change or if it was a phantom read/write error.

Review motion sensor raw data timestamps around 06:55 and 12:25 to see if any movement was detected despite 'Occupancy=0' reports.

Verify the source IP address or command origin for the window covering changes to distinguish between local automation scripts and external commands.

Cross-reference battery voltage levels of the front door lock to rule out low-battery causing erratic logic (false auto-lock/unlock).

Occupancy sensors are reporting false positive 'occupied' states in a rigid, repeating 3-minute cycle across multiple rooms while temperature data remains static and the bathroom sensor correctly reports empty, indicating a firmware loop or calibration failure rather than human presence.

Explanation: The occupancy logs show an impossible physical pattern where Kitchen -> Entrance -> Living Room -> Bedroom triggers occur every exactly 3 minutes (e.g., 11:55:00 to 12:00:00), which is characteristic of a software timer or stuck loop, not natural human movement.

Explanation: Crucially, while these rooms report occupancy=1, the bathroom_occupancy sensor explicitly reports 0 at 12:00:24 and 12:30:24, proving that occupants are not present in all reported locations simultaneously.

Explanation: Temperature readings remain relatively stable and do not reflect the dynamic heat signatures expected from humans moving between rooms at high frequency, further supporting the conclusion of sensor malfunction.

[2026-06-16T11:55:00] kitchen_occupancy | OccupancySensing.Occupancy = 1 ... [2026-06-16T12:00:00] kitchen_occupancy | OccupancySensing.Occupancy = 1 (Exact 5 minute reset interval)

[2026-06-16T12:00:24] bathroom_occupancy | OccupancySensing.Occupancy = 0 (Contradicts system-wide 'occupied' simulation)

No corresponding temperature spikes or motion duration variations during the rapid trigger sequences

Check the firmware version and event definition for the occupancy sensors to identify if a known bug causes periodic false triggers.

Reset the smart home hub and re-calibrate the PIR sensors to clear any internal state loops.

Verify battery levels on wireless sensors as low power can sometimes cause erratic behavior.

Simultaneous log entry of an 'Unlock' operation type and a 'Locked' state for the front door.

Check the raw binary payload or metadata of the occupancy sensor events between 11:55 and 12:10 to determine if they originate from the same PIR device or distinct sources.

Verify the firmware version and event definition mapping for the front_door_lock to confirm if LockOperationType=0 maps to 'Unlock' or if it represents a specific automation trigger that causes locking.

Cross-reference bathroom_occupancy logs to see if the '0' reading at 12:00:24 persists despite the system-wide 'occupied' simulation in other rooms.

Device activity patterns are consistent with a resident being present and actively using smart home automation (voice or app) while moving between rooms, rather than an intrusion or incapacitation.

Explanation: Occupancy sensors in the bedroom were continuously active throughout the entire 12-hour window, contradicting the hypothesis that the resident is absent or bedridden for extended periods without movement.

Explanation: Window covering changes at 12:36 and 13:51 occurred while the resident was confirmed present in the bedroom or adjacent living areas, indicating organic human control via voice/app rather than remote hacking.

Explanation: The cluster of events at 20:43 (Door contact -> Auto Lock -> Light On/Off -> Window Open) represents a coherent sequence of 'leaving' behaviors (securing door, adjusting lights/blinds) triggered automatically upon exit, which is standard smart-home functionality.

[2026-06-26T12:36:04] bedroom_occupancy | OccupancySensing.Occupancy = 1 (Present during first shade change)

[2026-06-26T13:51:04] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 0 (Shade changed while occupant still detected nearby)

[2026-06-26T20:43:17] front_door_contact | BooleanState.StateValue = True (Triggered Auto-Lock logic)

Monitor continued occupancy patterns to ensure no long gaps develop later in the timeline.

Review historical logs to confirm if the 'Auto' lock source behavior matches expected user routines.

Specific timestamp correlation: Window covering changes occur at 12:36 and 20:43. The second change happens almost simultaneously with the front door locking event (within 15 seconds), creating a suspicious temporal cluster.

High frequency of 'suspicious_signals' (60 salient events) versus low actual room activity (only 91 focus events out of 1057 total log entries) suggests automated noise or device manipulation rather than organic human behavior.

If the resident were simply sleeping or resting, one would expect consistent occupancy in the bedroom throughout the night hours (e.g., 00:00-08:00), but no such data is visible in the provided snippet, leaving the timeline gap ambiguous.

Check the raw log for the front_door_lock at 20:43:18 to determine if the lock state change (State=1) corresponds to unlocking (entry) or locking (exit), and verify if any human motion was detected immediately preceding this event.

Verify the source IP or MAC address associated with the window covering commands at 12:36:14 and 20:43:31 to distinguish between local app usage, voice assistant triggers, or potential remote hacking.

Cross-reference bathroom_water_leak_detector logs specifically during the time windows when occupancy sensors triggered in the bathroom (if any exist outside the summary) to rule out flooding or inability to use facilities.

Analyze the full timeline of bedroom_occupancy to see if there are long gaps (>4 hours) where the occupant is supposedly absent from their own room while other rooms show activity.

The sequence of events is consistent with a resident performing evening security routines (locking doors and closing windows) from inside the home, rather than an intrusion.

Explanation: Front door contact sensor triggered 'True' at 20:38:15 immediately preceding the auto-lock, confirming the door was open and subsequently closed by the system.

Explanation: Bedroom window closing command occurred 5 seconds after the lock, which aligns with standard post-occupancy security checks performed while inside.

Explanation: There is no evidence of forced entry, such as tamper alerts, motion sensors triggering outside expected patterns, or window contact sensors indicating an open state during the closing action.

Explanation: The absence of occupancy data gaps between the morning activity and the evening events suggests continuous monitoring without unauthorized access.

Status of the bedroom window contact sensor at 20:38:16 and 20:38:21 to verify if the window was open during the closing action.

Motion sensor logs for the hallway/entrance area between 11:59 and 20:38 to rule out missed entries/exits.

The house was vacant overnight with a significant temperature rise due to heating/AC cycles and window opening, followed by a normal automated unlock sequence upon the resident's return.

Explanation: Occupancy sensors consistently reported '0' (empty) from 00:00 until 20:37, confirming no one was inside during the night, but this is expected for an empty home rather than an anomaly.

Explanation: Temperature logs show a gradual increase (22°C to ~24°C) consistent with environmental changes (heating systems or open windows), not a fire event (which would cause rapid spikes) or sensor malfunction.

Explanation: The critical event at 20:37:14 shows the door unlocking ('Auto') immediately preceded by the front door contact being open ('True'), indicating the resident physically opened the door to enter, which then triggered the auto-lock cycle.

Explanation: Post-entry logs confirm occupancy detection in the bedroom shortly after the door unlock, verifying the resident entered normally.

[2026-06-22T20:37:19] bedroom_occupancy | OccupancySensing.Occupancy = 1

Review HVAC settings to ensure temperature rise overnight does not trigger false alarms.

Verify that the 'Auto' unlock logic correctly requires the door contact to be open before triggering.

Check raw motion sensor logs for the 2-hour window prior to 20:37:14 to confirm if there were missed detections or false negatives.

Verify if the 'Auto' unlock source corresponds to a geofence trigger based on mobile device location or a timer, rather than a physical proximity detection.

Review camera footage (if available) or doorbell log entries around 20:37 to see who/what triggered the entry.

Cross-reference the bedroom window opening events (14:06, 20:37) with temperature changes to rule out environmental causes.

Explanation: Occupancy sensors triggered at exact 3-minute intervals (Kitchen -> Entrance) followed by delayed Living Room triggers suggests either a programmed loop or a specific human behavior (checking rooms), not random intruder movement.

Explanation: Raw logs confirm the residence remained secure; the front door was only unlocked and opened much later at 20:51:10, well after the suspicious pattern ceased.

Explanation: No physical interaction evidence (door locks, window actuations) correlates with the occupancy spikes, ruling out active intrusion or tailgating.

Explanation: Temperature readings show normal fluctuations and no signs of forced entry or environmental hazards.

Strict 3-minute repetition of Kitchen/Entrance occupancy between 17:58 and 19:03 without corresponding door lock state changes.

Front door contact sensor shows 'True' (open) only at 20:51:10, indicating the house was secured during the anomaly window.

Living room occupancy consistently lagged by ~19 seconds after kitchen/entrance triggers, suggesting a predictable path rather than chaotic exploration.

Review historical logs for similar 3-minute patterns to determine if this is a recurring routine or a new device glitch.

Verify if any household member follows a strict check-in schedule that matches the observed timestamps.

Window covering adjustment (bedroom fully open/closed) occurring shortly after a period of high movement activity

Timestamps of door lock operations relative to entry/exit events to determine if the front door was opened/closed during this specific loop

Duration of stay in each room during the 17:58-18:13 window to confirm lack of 'lingering' typical of human activity

Sensor ID consistency to ensure no duplicate sensor readings are inflating the frequency of events

Contextual data on whether the elderly person has mobility issues that might explain slow, repetitive checking of rooms

Occupancy sensors are exhibiting a rigid, automated loop pattern with mathematically perfect intervals that contradicts natural human movement physics.

Explanation: Analysis of raw logs reveals occupancy events occurring at exact 2-minute intervals (e.g., Bedroom at :00, Living Room at :12, Kitchen at :00) across multiple cycles.

Explanation: The sequence is identical in every iteration (Bedroom -> Living Room -> Kitchen -> Entrance), which is statistically impossible for unassisted human behavior due to variable dwell times and transit speeds.

Explanation: Temperature sensor readings show minor fluctuations unrelated to the strict occupancy loop, suggesting the physical environment is static while only the occupancy state is being artificially toggled.

Verify if a robot vacuum or cleaning bot is physically triggering the IR/pIR sensors via repeated passes.

Check network logs for repeated UDP/TCP packets from a single IP address targeting the occupancy gateway to rule out a spoofing attack.

Reset the affected occupancy sensors or firmware update if software logic error is suspected.

[2026-06-23T17:55:00] kitchen_


The detected pattern corresponds to a resident executing a 'Goodnight' automation routine after the house was fully vacated and temperatures stabilized, with no signs of intrusion or malfunction.

Explanation: Occupancy sensors showed synchronized presence across all rooms every 5 minutes from 17:55 to 19:00, consistent with a resident moving through the house for evening tasks (cooking, cleaning) rather than continuous occupancy.

Explanation: Between 19:00 and 20:40, there is a complete absence of occupancy events and a steady decline in room temperatures (e.g., kitchen dropped from ~23°C to ~22°C), confirming the house was empty and cooling down naturally.

Explanation: At 20:40, the door locked automatically ('Auto') followed immediately by lights turning on briefly then off, and window coverings closing; this specific sequence matches a standard 'Away/Goodnight' smart home scenario triggered by an empty-house condition or timer, not an intruder.

No occupancy events recorded between 19:00 and 20:40, with temperature logs showing the house cooling down during this gap.

The action sequence at 20:40 (Lock -> Light Toggle -> Close Curtains) represents a logical closure routine rather than an emergency response or forced entry attempt.

Verify if the 'Goodnight Mode' automation schedule aligns with the user's typical evening departure time.

Monitor future logs to ensure the automation does not trigger falsely when the house is actually occupied.

Bedroom window coverings set to fully closed (100%) shortly after the door was locked.

Pattern of repeated, synchronized occupancy triggers across all zones without clear context of who triggered them.

Check for 'Unlock' operations on the front door prior to 20:40:09 to determine if the user entered.

Verify the timestamp and source of the 'Auto' lock command; check if it was triggered by an automation rule (e.g., 'Goodnight Mode') or a third-party access event.

Analyze the raw motion sensor data between 18:10 and 20:40 to confirm if the house was truly empty during this gap.

Cross-reference with camera feeds (if available) or other smart device logs (phone location, smartwatch) around 20:40 to see if the resident was physically present inside or outside.

The observed rapid room-to-room movement and automated window opening are consistent with a resident performing normal evening routines (cleaning/maintenance) rather than being trapped or incapacitated.

Explanation: The raw log shows a highly repetitive pattern of occupancy in the entrance and living room immediately followed by bedroom/kitchen occupancy (e.g., 11:55-12:40). This 'ping-pong' behavior is characteristic of someone tidying up or checking multiple zones systematically, not frantic panic or being stuck.

Explanation: Crucially, at 20:50:16, the front door contact sensor triggered state True (door opened), which directly contradicts the hypothesis that the door was locked shut while the occupant was inside. The subsequent 'Auto' lock operation at 20:50:17 indicates the resident entered, the system automatically secured the door behind them (a standard safety feature), and then they proceeded to open the bedroom window.

Explanation: The sequence of events—Door Open -> Auto Lock -> Bedroom Light On -> Window Raised -> Light Off—is a logical, coherent routine for airing out the house or preparing for sleep, not an attempt to escape a confinement.

[2026-06-15T20:50:16] front_door_contact | BooleanState.StateValue = True

Repetitive timestamp patterns showing systematic zone checks (e.g., 11:55 Entrance->Living, 12:03 Bedroom->Kitchen) indicative of cleaning or maintenance.

Logical automation chain: Door Open triggers Auto-Lock, followed minutes later by manual window adjustment and lighting changes.

Monitor for future deviations from this established routine pattern.

Occupancy sensors triggering in rapid succession across different zones could indicate a pet wandering around or a glitchy sensor bouncing between states.

For a pet scenario, there would likely be more varied room usage patterns over 12 hours, not just clustered activity in the morning/afternoon and then nothing until evening.

The specific time correlation between the door lock auto-locking and the window opening (20:50:17 and 20:50:28) is too precise for random noise, implying a deliberate action or a very specific automation rule chain.

Check the raw log for the source of the 'Auto' lock operation at 20:50:17. Was the door physically closed by a human, or did a timer trigger it?

Verify the state of the bathroom door and other internal doors around 20:50. Are they locked? Is the occupant still inside?

Cross-reference the 'window_covering' event at 20:50:28 with the actual camera feed or window contact sensor to confirm if the window was actually opened or just the blinds raised.

Review the temperature and smoke alarm logs for any anomalies during the period of frantic movement (11:55 - 12:10).

Explanation: The raw log shows an identical sequence of room triggers (Kitchen -> Bedroom -> Entrance -> Living Room) repeating every ~5 minutes with exact timing offsets (e.g., +3s for Entrance, +4s for Living Room).

Explanation: Human movement is stochastic and task-based; no single individual can traverse four distinct rooms in under 10 seconds repeatedly without biological impossibility (average speed exceeds sprint limits by factors of 10-20x).

Explanation: The rigid periodicity confirms the source is deterministic system logic or a stuck sensor state propagating through the home network, not organic presence.

[2026-06-21T17:58:00] kitchen_occupancy ... [17:59:00] bedroom_occupancy ... [18:04:03] entrance_occupancy

Consistent internal latencies within each cycle (e.g., Bedroom to Entrance is always exactly 3 seconds)

Immediately reboot the motion sensor gateway or affected nodes to reset the triggering loop.

Check device logs for known firmware bugs related to 'rapid re-trigger' or 'ghost occupancy'.

Schedule a technician visit to recalibrate sensors or replace units if software update fails to resolve the issue.

Potential environmental interference causing false positive motion detections.

All motion sensors trigger simultaneously or in rapid succession across distant rooms.

Temperature patterns are empty ([]), suggesting no thermal anomalies were detected by other sensors to correlate with the motion, though this could be a data extraction issue.

If it were dust or pets, one might expect random clustering in specific zones (like near windows or doors) rather than a perfect loop visiting every room in sequence.

[2026-06-21T18:04:08] living_room_occupancy | OccupancySensing.Occupancy = 1

Raw infrared beam breakage logs or PIR delta values for the specific timestamps identified to check for signal strength/spike magnitude.

Camera snapshot metadata or video clips associated with the occupancy events to visually confirm presence vs. absence.

Device firmware version and last calibration date for all motion sensors to rule out known bugs causing loop-triggering.

Correlation with ambient light levels to see if motion detection is triggered by sudden lighting changes (e.g., curtains closing/opening).

Evidence confirms a successful forced entry at 07:04:11 where the door was manually unlocked, the contact sensor registered an 'open' state while the lock remained engaged (indicating manual override or bypass), and the occupant subsequently opened bedroom curtains.

Explanation: The log shows a sequence starting with a manual unlock command at 07:04:09 followed immediately by the physical door contact sensor reporting 'False' (Open) at 07:04:11.

Explanation: Contradicting a normal exit/entry pattern, the front door lock state remained 'Locked' (2) at 07:04:09 when the door was physically open, suggesting the intruder forced the door open without disengaging the latch electronically, or used a tool to bypass the lock before re-locking it automatically at 07:04:16.

Explanation: Following this event, the bedroom window covering retracted at 05:38 (previously noted as potentially suspicious timing, but now confirmed to be part of a sequence of securing/revealing access points) and later at 12:35 when occupancy was detected, indicating an intruder familiarizing themselves with the interior or preparing for departure.

[2026-06-08T07:04:11] front_door_contact | BooleanState.StateValue = False

Immediately notify law enforcement and provide timestamped logs of the forced entry attempt.

Review camera footage from the entrance and interior hallway between 07:00 and 07:20.

Change all smart lock credentials and enable temporary lockdown mode if available until the system is verified secure.

Rapid toggle of front door lock state within 7 minutes (Lock -> Unlock), potentially indicating testing of the lock mechanism or a break-in attempt where the intruder unlocked the door multiple times before entering.

Manual unlock of front door at 07:04:09 immediately preceding an automatic unlock event at 07:04:16.

Bedroom window coverings retracting (opening) shortly after the front door was manually unlocked.

Multiple rapid toggles between locked and unlocked states on the front door.

Motion sensor events in the hallway, kitchen, and entrance leading up to and following the 07:04:09 timestamp to detect if anyone entered.

Audio logs or microphone data from the entrance and bedroom around 07:04:00 to 07:10:00 for sounds of struggle or breaking glass.

Detailed timestamps of the 'WindowCovering' change at 05:38:11 vs the door interaction to determine causality (did the user wake up early? or did they react to something?).

Camera footage (if available) for the entrance and bedroom windows between 05:30 and 07:15.

Sequence of events at 07:05 indicates a potential tailgating incident where a door was manually locked from the inside while an unauthorized individual remained in proximity, triggering an automatic re-unlock.

Explanation: At 07:05:04, the front door contact sensor registered 'False' (door open), immediately followed by a 'Manual' lock command and state change to 'Locked'.

Explanation: Crucially, at 07:05:11, the door contact sensor reverted to 'True' (door closed) only 7 seconds after being locked manually, suggesting someone held the door or lingered outside preventing the system from registering a clean exit.

Explanation: This lingering presence triggered an 'Auto' unlock command at 07:05:12, which is inconsistent with normal resident behavior (who would typically leave and have the door remain closed or lock automatically without immediate manual intervention causing a reopen cycle).

Explanation: While the late evening event (20:39) shows similar patterns, it occurs after the last known occupancy sensor reading (entrance_occupancy=1 at 13:55), making it more likely a delayed automated response or false positive rather than active intrusion.

Review video footage from the front door camera specifically for the 07:04:00 - 07:06:00 window to identify if two individuals were present.

Inspect the physical condition of the door handle and strike plate for signs of forced entry or manipulation during that timeframe.

Update security policies to require confirmation or delay auto-unlocks if the door remains open longer than a standard threshold after a manual lock attempt.

No explicit 'manual lock' event recorded immediately before the 20:39:16 auto-unlock, though state changed from 2 to 1.

Simultaneous proximity of Manual Lock (07:05:04) and Auto Unlock (07:05:12) suggesting someone entered while another person might still be inside or manipulating the sensor.

Late evening Auto Unlock (20:39:16) occurring after the resident likely left home, coupled with immediate window closing, which could indicate a delayed alarm reset or post-intrusion concealment.

Extended period of zero occupancy across all zones from 00:00 to 08:20 without any motion events logged, despite the high total event count (1850), suggesting potential sensor blind spots or data gaps during critical night hours.

Check raw camera feeds or doorbell logs for the time range 07:04:00 - 07:06:00 to verify if two different individuals were present near the entrance.

Verify the specific sensor ID triggering the 20:39:16 Auto Unlock; was it triggered by the user exiting via phone/app, or by a physical sensor breach?

Cross-reference the 00:00:00 - 08:20:00 gap with utility meter logs or smart plug energy consumption to confirm if the house was truly unoccupied or if devices were active.

Inspect the history of the `front_door_lock` to see if there were failed lock attempts or tamper alerts around 07:05 and 20:39 that were filtered out in the summary.

Automated security lockdown triggered by an unlisted sensor breach (likely bedroom window) detected via rapid sequence of window closure followed immediately by front door auto-locking.

Explanation: The raw log reveals a precise causal chain: at 23:07:13 the bedroom window shade closed (100%), and exactly 10 seconds later at 23:07:23 the front door locked automatically.

Explanation: This 'secure periphery' sequence indicates the home automation system reacted to a specific trigger event occurring around 23:07:13. Given the context, the most probable trigger was a breach of the bedroom window contact sensor (which would cause the shade to close and then trigger the 'Away' or 'Secure Home' routine).

Explanation: Although no explicit 'window open' state change is listed in the provided snippet, the tight temporal coupling between the window action and the door lock confirms the system detected an anomaly it deemed critical enough to secure the entire perimeter, suggesting a potential intrusion attempt.

Immediately verify if anyone is currently inside the house via live camera feeds.

Check physical status of the bedroom window to confirm if it was opened/closed unexpectedly.

Review full sensor logs for the exact timestamp of the bedroom window contact sensor state change to identify the breach point.

Simultaneous (within 1 minute) full closure of bedroom window shade and automatic locking of the front door.

Lock operation source is 'Auto' without explicit motion trigger listed in the same time window, implying a rule-based reaction to an unlisted anomaly (e.g., window open state change).

Check raw logs for the bedroom window contact sensor status around 23:06-23:07 (was it opened?

Search for any alarm triggers, smoke/CO alarms, or leak detector activations between 23:00 and 23:10.

Verify the configuration of the 'Auto' lock rule: Does it trigger on window open/close? On motion outside? Or is it a scheduled task?

Cross-reference user app activity logs to see if the owner manually initiated a 'Secure Home' routine at 23:07.
