1分钟内多次灯光开关 可能原因：智能家居系统被入侵/远程控制；设备自动化规则冲突；或电路问题 也可能是恐慌信号（住户通过反复开关灯试图引起注意）

通知住户检查是否有人误操作或系统异常

The window state change at 21:50 was preceded by resident occupancy and light activation in the bedroom, indicating an authorized internal operation rather than an intrusion.

Explanation: At 06:19:08, the window covering changed state while the house was empty; however, this occurred after a resident entered the bedroom at 06:19:00 and turned on the light, followed by them leaving (occupancy returned to 0) and locking the front door at 07:15. This sequence confirms a routine morning exit.

Explanation: At 21:50:30, the window covering changed state again. Crucially, this event is immediately preceded by the resident turning on the bedroom light at 21:50:27, proving they were present inside the room and manually operated the device.

Explanation: The front door logs show standard manual lock/unlock cycles consistent with residents arriving and leaving at typical hours (07:15 and 18:01), with no forced entry indicators or alarm triggers observed.

[2026-06-10T21:50:27] bedroom_light | OnOff.OnOff = True

Continue monitoring for any future unsolicited window state changes that do not correlate with motion sensor data or lighting events.

The high room_activity counts in kitchen/living_room suggest recent movement that might not align with current empty status if the logs represent a specific short window vs long term history, but strictly within the provided evidence packet, all occupancy states are 0.

bedroom_window covering position change from 0% (closed) to 10000 (likely open or error state indicating opening) between 06:19 and 21:50 while the house appears unoccupied at night.

Potential correlation between the early morning window opening and subsequent manual lock operations could indicate an intruder attempting to gain access or exit undetected.

Timestamps of 'front_door_lock' events relative to the 'bedroom_window' state changes to confirm if anyone entered/exit immediately after the window opened.

Raw motion sensor data for 'bedroom', 'living_room', and 'kitchen' specifically around 06:19:08 and 21:50:30 to detect if any movement coincided with the window state change.

History of the 'bedroom_window' contact sensor (if available separately from the covering motor) to see if the physical window was actually breached or just mechanically manipulated.

Check system logs for any alarm triggers or unusual battery/voltage drops on the bedroom window device around the time of the state change.

SmokeCoAlarm 的 COState 变为 Warning 或 Critical

CO 报警是严重安全事件，不同于烟雾报警

紧急通知所有住户撤离，开窗通风，联系燃气公司

The kitchen temperature sensor is reporting physically impossible values (ranging from 22°C to 25°C represented as 2200-2500), indicating a sensor failure that has triggered false CO and smoke alarms.

Explanation: Occupancy logs confirm the house was empty between 00:00 and 08:30, ruling out human presence or cooking activities.

Explanation: Kitchen temperature readings show a linear drift from ~2272 to ~2516 over 8 hours, which corresponds to normal ambient room temperatures (22-25°C) if the 'x100' unit factor is applied; raw values of 2400+ are impossible for indoor environments.

Explanation: The CO alarm and ExpressedState=2 occurred at 03:34 when the reported temperature was 2380 (~23.8°C), proving the alarm was triggered by the erroneous high reading rather than actual combustion or gas leakage.

[2026-06-06T00:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2272

[2026-06-06T03:34:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2380

Immediately replace or recalibrate the kitchen temperature/smoke sensor.

Inspect the sensor wiring or power supply for intermittent faults causing data overflow.

Reset the smoke/CO alarm system after hardware replacement.

Video footage or motion sensor granularity logs for the kitchen between 03:00 and 04:00 to rule out pets or automated appliances triggering the alarm.

火灾风险警报，建议住户检查该区域电器

The sequence of events indicates residents cooking late at night, leaving the house in the early morning (01:30), and returning later, with no signs of intrusion or malfunction.

Explanation: All occupancy sensors remained at 0 between 00:00 and 07:28, confirming the house was empty during the reported 'unlocked' period.

Explanation: The kitchen temperature rose steadily from ~22°C to ~25°C, consistent with heating up a home for cooking rather than a fire emergency.

Explanation: The smoke alarm activated at 01:30 but there is no subsequent log indicating a sustained high-heat event or manual reset required; the temperature continued rising normally until morning.

Explanation: At 06:35, occupancy sensors detected residents entering (bedroom/bathroom lights on), followed immediately by the front door being manually locked at 07:28, which aligns perfectly with residents returning after an overnight absence.

Explanation: The window opening at 06:35 correlates directly with the arrival of occupants who turned on lights, ruling out unauthorized entry.

[2026-06-01T06:35:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-01T01:30:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2300

Review historical logs to identify if the resident habit of leaving doors unlocked while absent is intentional or needs adjustment in security settings.

Check if the bedroom window opening at 06:35:10 correlates with sunrise/light sensors or user interaction logs.

Evidence strongly suggests an unauthorized person entered the home via tailgating after a resident unlocked the front door at 07:14 AM, as indicated by the immediate door contact closure followed by automatic re-locking.

Explanation: At 07:14:18, a manual unlock command was issued, changing the lock state to 'Unlocked' (2).

Explanation: At 07:14:20 (exactly 2 seconds later), the front door contact sensor registered as False (open/closed transition indicating someone passed through or the door swung open).

Explanation: At 07:14:26 (8 seconds after the initial unlock), the system automatically re-locked the door without any subsequent manual lock command from a resident inside, which is inconsistent with normal entry behavior where a resident would manually secure the door upon entering.

Explanation: The sequence of Unlock -> Door Movement -> Auto-Lock within a 8-second window aligns perfectly with a tailgating event rather than a glitch.

[2026-06-22T07:14:20] front_door_contact | BooleanState.StateValue = False

Review doorbell camera footage immediately around 07:14 AM to identify if a second individual followed a resident out and back in.

Check security logs for any other unusual access patterns or failed lock attempts during that timeframe.

Update smart-home automation rules to require manual confirmation before auto-locking if occupancy sensors detect presence inside, or verify current sensor calibration.

House is currently vacant/empty: Multiple occupancy sensors across living room, bedroom, and bathroom have reported zero occupancy since early morning (00:00).

[2026-06-22T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

[2026-06-22T00:00:00] bedroom_occupancy | OccupancySensing.Occupancy = 0

[2026-06-22T00:00:00] bathroom_occupancy | OccupancySensing.Occupancy = 0

[2026-06-22T01:30:00] living_room_occupancy | OccupancySensing.Occupancy = 0

Door lock state transition: Manual unlock (State 2) followed immediately by Auto-lock (State 1) without a subsequent manual lock command, which is inconsistent with typical entry patterns.

Time of anomaly: The suspicious door event occurred at 07:14 AM, coinciding with the time residents typically leave for work/school, increasing the risk of someone following them in or being locked out incorrectly.

Check raw motion sensor data for the entrance hallway between 07:14:18 and 07:14:26 to see if anyone entered or lingered before the auto-lock triggered.

Verify the specific 'LockOperationType=1' payload to confirm if it was a 'Unlock' action or a 'Lock' action misinterpreted by the parser (e.g., Type 1 might mean 'User Initiated' regardless of direction, requiring cross-reference with the resulting State change).

Check camera footage (if available) or doorbell logs around 07:14 AM to visually confirm who interacted with the door.

紧急通知所有住户撤离，开窗通风，联系燃气公司

A forced entry event occurred in the early morning hours involving the bedroom window and front door, indicated by a coordinated sequence of window opening followed immediately by door unlocking.

Explanation: The raw log shows a distinct sequence starting at 2026-06-17T06:34:07 where the bedroom window covering was opened (transition to 0), followed 3 seconds later by the front door being unlocked via an 'Auto' source at 06:50:00. This tight temporal proximity suggests a coordinated escape or entry rather than independent events.

Explanation: Contradicting the Stage-1 hypothesis that residents were awake at night, occupancy sensors show all rooms empty from midnight until 06:32, confirming the house was unoccupied during the incident window.

Explanation: While a Carbon Monoxide alarm triggered at 23:08, the temperature logs show kitchen temps dropping to normal levels (~2258) prior to this, making a CO leak unlikely; the primary immediate threat remains the confirmed physical breach.

[2026-06-17T06:50:00] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Occupancy sensors recorded '0' for all rooms between T00:00 and T06:32

Contact local law enforcement immediately to report a break-in.

Do not enter the property until authorities have secured it.

Check for signs of forced entry at the bedroom window and front door upon safe access is granted.

Timestamps and sensor IDs for any other CO readings prior to 23:08:00 to determine duration of exposure.

Status of kitchen appliances (cook_surface, dishwasher) around 22:15 - 23:08 to identify CO source.

Audio logs or motion sensor granularity in the bedroom hallway/living room between 22:15:34 and 22:15:38 to verify if someone physically entered/exited.

History of front_door_lock LockOperationType near 22:15:38 to confirm if the unlock was manual or auto-triggered by an intruder.

假期/出差模式中出现活动

Evidence indicates a potential unauthorized entry into the bedroom at night, characterized by an unexplained window opening followed immediately by the front door unlocking while occupancy sensors reported the home as empty.

Explanation: Occupancy sensors consistently reported '0' (empty) for all rooms between 21:47:21 and 06:31, with no human activity detected until morning.

Explanation: At 21:47:27, the bedroom window cover moved to fully open (10000), an event that lacks any preceding manual command or automation trigger in the logs.

Explanation: Two minutes later at 21:47:31, the front door lock changed from locked to unlocked (Source: Auto) despite no resident being inside to exit; this suggests a system override triggered by the intrusion detection sequence or forced entry.

Explanation: The absence of motion sensor data in the provided log snippet does not negate the physical evidence of the window opening and subsequent door unlock during a verified empty house state.

[2026-06-15T00:00:00] ... OccupancySensing.Occupancy = 0

Immediately contact local law enforcement to report a suspected break-in.

Check physical security of the bedroom window and front door for signs of forced entry.

Review full camera feeds (if available) specifically for the time window 21:47:00 - 22:00:00 to identify the intruder.

Temporarily disable automatic door unlocking features until the investigation is complete.

[2026-06-15T21:47:31] front_door_lock | DoorLock.LockState = 1

Bedroom window covering moved to fully open position (10000/10000) at 21:47:27 while occupancy sensors reported '0' for all rooms at 00:00:00 and subsequent intervals.

Front door lock state changed to '1' (unlocked) at 21:47:31, which coincides suspiciously with the window opening event.

Check if any motion events occurred in the bedroom between 21:47:27 and 21:47:31.

Verify the specific operation source and command ID for the window covering movement at 21:47:27 to rule out remote automation commands.

Inspect the front_door_lock log immediately preceding 21:47:31 to determine if the unlock was manual, auto-unlock upon exit detection (which seems inconsistent with the timeline if no one entered), or a system override.

Cross-reference kitchen and living room logs around 21:47 to see if any lights were toggled or appliances used before the window opened.

The sequence of events represents a normal morning routine where residents opened the front door (detected by contact sensor), locked it manually, and the system subsequently re-locked it automatically upon detecting occupancy or as part of its schedule; no signs of forced entry or unauthorized access are present.

Explanation: Occupancy sensors reported '0' (empty) from midnight until 02:30, confirming the house was indeed empty during the early morning hours in question.

Explanation: At 07:39:19, the door lock state changed to 'unlocked' via a manual operation, immediately followed by the door contact sensor registering 'open' (False) at 07:39:21, proving physical interaction occurred.

Explanation: The subsequent 'Auto' unlock event at 07:39:28 corresponds to the door closing (contact sensor True) and the system resuming its automated locking cycle, consistent with a resident entering the home rather than an intrusion attempt.

[2026-06-16T07:39:27] front_door_contact | BooleanState.StateValue = True

High frequency of lock operations (4 events in the log snippet) compared to typical user behavior.

Check the specific timestamp difference between the Auto-unlock event and the subsequent Manual-lock event to determine if it was human reaction time or automated logic failure.

Cross-reference the 'Auto' unlock source ID with known device identifiers to ensure it wasn't triggered by an external signal injection.

Verify if the occupancy sensors have been reporting '0' consistently before the 07:39 events to confirm the house was truly empty during the interaction.

A significant and sustained temperature rise in the kitchen (from ~22°C to ~25°C) preceded the smoke alarm trigger at 02:00 AM, indicating a confirmed fire hazard rather than a sensor malfunction or false positive.

Explanation: Kitchen temperature rose steadily from 00:00 (22.76°C) to 02:00 (23.34°C), then continued climbing past 24°C until morning, which is abnormal for an empty house.

Explanation: The smoke alarm triggered exactly at 02:00 AM while occupancy sensors confirmed all rooms were empty, ruling out human activity as the immediate cause of ignition.

Explanation: No other anomalies (like door breaches or window tampering) contradict this finding; the data supports a single isolated fire event during sleeping hours.

[2026-06-26T02:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2334

Immediately inspect the kitchen for smoke damage, burnt items, or electrical faults.

Replace the smoke alarm battery or unit if it was not reset automatically, and test all connected alarms.

Evidence indicates a potential break-in where an intruder entered the bedroom around 23:02, triggered a window actuator (possibly via force or manipulation), and exited through the front door which then auto-locked.

Explanation: Occupancy sensor detected a person entering the bedroom at 23:02:08 despite the house being empty all night.

Explanation: Immediately after occupancy detection, the bedroom window motor was commanded to full extension (100%) at 23:02:16, suggesting forced entry through the window or a deliberate action by someone inside.

Explanation: The front door contact opened (True) at 23:02:21 followed immediately by an 'Auto' lock operation, consistent with a burglar exiting via the main entrance after breaching another point.

Explanation: The sequence of events (Entry -> Window Manipulation -> Exit -> Auto Lock) within 14 seconds strongly contradicts normal resident behavior like routine adjustments.

[2026-06-20T23:02:08] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-20T23:02:21] front_door_contact | BooleanState.StateValue = True

Contact local law enforcement immediately to report a suspected burglary.

Dispatch security personnel to the residence if available.

Review video surveillance footage from cameras facing the bedroom window and front door for visual confirmation.

Temporal clustering: Bedroom window fully opened (10000) then immediately closed (0) at 23:02:16, followed by Front Door Auto-Lock at 23:02:22.

Door Lock Source: 'Auto' lock operation at night without a preceding manual unlock/lock cycle typically associated with resident presence.

Zero occupancy confirmed in all sensitive areas (Bedroom, Living Room, Bathroom) during the suspicious event window.

Check raw motion sensor logs for the 30-minute window preceding 23:02 to rule out missed detection or sensor blind spots.

Verify the exact duration and speed of the bedroom window motor command to distinguish between a glitch and a forced manipulation.

Cross-reference smart home app access logs to see if an external user initiated the auto-lock or window commands.

Review camera feeds (if available) or doorbell logs specifically around 23:02:00 to visualize the entrance interaction.

Evidence indicates a forced entry attempt where the door was manually locked, immediately opened (bypassing or compromising the lock), and then auto-unlocked.

Explanation: The log shows a manual lock event at 07:29:12 followed by a door contact sensor transition from Closed (False) to Open (True) at 07:29:14, proving the door was physically opened while locked.

Explanation: Immediately after the door was opened, the system triggered an automatic unlock at 07:29:20, suggesting either a compromised lock mechanism that failed to stay locked, a security protocol bypass, or an attempted forced exit/entry sequence.

Explanation: The subsequent return of the door contact to 'Closed' (True) confirms the door was manipulated rather than just briefly touched, consistent with an intrusion attempt.

[2026-06-22T07:29:19] front_door_contact | BooleanState.StateValue = True

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

Check video footage if available to confirm if anyone entered during the 07:29 window.

Test the auto-lock feature and battery levels on the front door lock to ensure it functions correctly.

[2026-06-22T00:00:00] bedroom_occupancy | OccupancySensing.Occupancy = 0

Timestamps surrounding the 07:29 Manual Lock/Auto Unlock pair to check for keypad codes, app usage, or physical tampering indicators.

Door contact sensor state transition logs to verify if the door was actually opened between the manual lock and auto unlock events.

Battery voltage levels of the smoke alarm to confirm if it is low vs. just an alert trigger.

烟雾报警器低电量时发生事件

警告住户烟雾报警器可能失灵，建议更换电池/设备

High probability of unauthorized entry via bedroom window followed immediately by an automated front door unlock, suggesting a compromised security system or remote access.

Explanation: At 22:14:39, the bedroom window was forcibly opened to 100% (ajar), while occupancy sensors still reported 0, indicating an intruder bypassed passive motion detection.

Explanation: Exactly 7 seconds later at 22:14:46, the front door lock triggered an 'Auto' unlock event. This sequence is inconsistent with normal user behavior (who would not open a window and then auto-unlock the main door from outside) and suggests either a hacked automation script or a sophisticated physical attack on the lock's logic.

Explanation: The lack of smoke/fire alarms rules out H3 and fire-related false positives, leaving the coordinated window/door event as the primary security threat.

[2026-06-01T22:14:39] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Immediately change all smart home account passwords and enable MFA if not already active.

Check mobile app logs for any unrecognized device locations or command history around 22:14.

Physically inspect the bedroom window area for signs of tampering or forced entry tools.

Temporarily disable automatic door unlocking features until the security breach is investigated.

Timing discrepancy: Window opens at 22:14:39, Door unlocks at 22:14:46. This implies either a pre-programmed 'return home' automation that was triggered incorrectly, or an intruder who opened the window and then remotely/unlocked the door.

Check if any command was sent from a mobile app or smart speaker to unlock the front door at 22:14:46.

Verify the source IP or device ID associated with the front_door_lock auto-unlock event.

Review camera footage (if available) or motion sensor logs for the bedroom and entrance hallway specifically between 22:14:30 and 22:15:00 to see if a person entered before the door unlocked.

Confirm the logic of the 'Auto' unlock trigger (e.g., geofence exit vs. manual override).

A manual door unlock event occurred at 07:24 while all internal occupancy sensors reported zero occupants for over seven hours, strongly indicating an unauthorized entry.

Explanation: Occupancy sensors consistently reported '0' (empty) in the living room, bedrooms, and bathroom from 00:00 until 06:41, suggesting the household was absent or asleep during the early morning hours.

Explanation: At 07:24:14, a manual lock operation (LockOperationType=1) triggered on the front door, followed immediately by the door state changing to unlocked (State=2).

Explanation: The sequence of events—door contact going False (open), then True (closed), followed by an automatic re-lock (Auto)—confirms physical interaction with the door while no one was detected inside, ruling out normal residents waking up.

Explanation: Contradiction of Hypothesis H2: The hypothesis that members were asleep is contradicted by the lack of occupancy detection in sleeping areas prior to the incident and the manual nature of the door event.

Immediately notify local law enforcement regarding a potential burglary attempt.

Secure the property and do not enter until authorities have inspected the premises.

Review historical camera footage if available to identify the intruder's vehicle or appearance before police arrival.

立即提醒住户关闭灶具，如无法联系则自动关闭（如支持远程关闭）

A severe kitchen fire event occurred at 06:38 triggered by a smoke alarm and extreme temperature spike, followed by residents leaving the premises and manually locking the door.

Explanation: At 06:23, the kitchen cook surface was turned on while occupancy in the living room was zero, indicating unattended cooking conditions.

Explanation: At 06:33, the kitchen temperature sensor reported an extreme value of 3500 (likely celsius or raw count indicating failure/extreme heat), immediately preceding the smoke alarm trigger at 06:38.

Explanation: Occupancy logs confirm that after the alarm (06:38), residents were present in the bedroom and bathroom (06:35-07:33) before the front door was manually locked at 07:33, confirming evacuation rather than tampering.

Explanation: The sequence of unattended cooking -> extreme heat/spike -> smoke alarm -> evacuation constitutes a confirmed fire risk incident.

[2026-06-03T06:23:00] kitchen_cook_surface | OnOff = True

[2026-06-03T06:33:00] kitchen_temp_sensor | MeasuredValue = 3500

Immediately inspect the kitchen for soot, damaged appliances, or residual fire hazards.

Check the kitchen temperature sensor hardware; a reading of 3500 suggests sensor malfunction or destruction and requires replacement.

Review insurance claims regarding potential property damage from the 06:38 fire event.

Inconsistent occupancy pattern: All rooms report zero occupancy during early morning hours (00:00 - 01:00), but significant activity counts exist for other times. While normal for night, combined with the unexplained window opening at 21:46 (after which the house seems empty again until day), it raises questions about who or what entered the premises.

[2026-06-03T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

[2026-06-03T00:30:00] bedroom_occupancy | OccupancySensing.Occupancy = 0

Check raw motion sensor logs for the bathroom and kitchen between 06:30 and 07:45 to see if anyone was present when the smoke alarm triggered.

Verify the source of the 'WindowCovering' command at 21:46 to determine if it was a motorized actuation (tampering) or a user interaction.

Cross-reference the time difference between the smoke alarm trigger (06:38) and the first manual door lock (07:33) to confirm if the resident was inside or outside the home during the smoke event.

Inspect contact sensor logs for the bedroom window specifically at 21:46 to see if the window was actually physically breached/opened versus just the cover moving.

No security threat detected; the observed events are consistent with residents preparing for sleep and a smart home automation routine.

Explanation: Occupancy logs confirm all rooms were empty (0) from 00:00 until 06:38, establishing that no one was inside during the initial blind closure at 06:38.

Explanation: The 'Auto' source for the door unlock at 21:53:31 correlates perfectly with the resident turning on the bedroom light at 21:53:20, indicating an authorized wake-up or departure sequence rather than unauthorized access.

Explanation: The sequence of opening blinds then unlocking the front door is logically explained by a homeowner checking outside conditions before leaving the house, supported by the subsequent occupancy change in the living room at 21:54:06.

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

[2026-06-10T21:53:20] bedroom_light | OnOff.OnOff = True

[2026-06-10T21:53:31] front_door_lock | OperationSource=Auto

Review smart home automation schedules to ensure the 'Auto' unlock trigger aligns with expected wake-up times.

Verify if the window cover motor requires manual override or scheduled maintenance given its operation without explicit user command logs.

Timestamp correlation: Bedroom blinds opened at 21:53:24, immediately followed by Front Door Unlock at 21:53:31.

Night-time blind position change: Blinds moved from closed (0%) at 06:38 to open (10000) at 21:53 without explicit manual control logs shown in snippet.

Door lock state volatility: Multiple rapid transitions between locked (2) and unlocked (1) states on the front door within a short timeframe (e.g., 07:34:12 vs 07:34:19).

Check raw logs for 'bedroom_occupancy' between 21:45 and 22:00 to confirm if anyone was present when blinds opened.

Verify source of the 'Auto' lock operation at 07:34:19 and 21:53:31 to determine if it's a smart home automation routine or anomalous behavior.

Cross-reference 'bedroom_window' contact sensor status around 21:53 to see if the window itself was opened/closed during the blind adjustment.

Review 'living_room_occupancy' and 'kitchen_occupancy' logs around 21:53 to rule out family members manipulating devices remotely or physically.

烟雾报警器低电量时发生事件

烟雾报警器处于低电量状态
厨房有高温活动但烟雾传感器未触发
两个信号组合：低电量 + 温度上升但烟雾传感器无反应 → 设备可能失灵

The household is under active intrusion risk indicated by forced entry attempts at the front door and suspicious window manipulation in the bedroom coinciding with door locking events.

Explanation: Front door contact sensor shows a clear 'open' state (False) between 07:13:29 and 07:13:31, confirming physical entry/exit rather than just manual handle operation, followed immediately by an auto-lock.

Explanation: A second identical sequence occurred at 18:29:02 where the door was physically opened before being locked automatically.

Explanation: At 22:05, the bedroom window was opened from closed to fully open within seconds of the front door being auto-locked, suggesting coordinated access points or someone inside manipulating both points to simulate presence while potentially bypassing security.

Explanation: All reported occupancy sensors show zero occupancy during these critical intervals (except for brief moments before the door interaction), implying no resident triggered these actions normally.

[2026-06-09T07:13:29] front_door_contact | BooleanState.StateValue = False

[2026-06-09T07:13:31] front_door_contact | BooleanState.StateValue = True

Immediately change all smart lock codes and credentials associated with the front door.

Contact local law enforcement to report the suspicious activity and potential break-in attempt.

Review video footage from exterior cameras if available to identify suspects.

The specific sequence of 'Manual Unlock -> Auto Lock' occurring multiple times within short intervals or irregularly might not align with standard routine if no occupancy is detected during transitions.

Suspicious window covering manipulation in the bedroom around 22:05, potentially indicating someone trying to open blinds from outside or tampering before locking the door.

[2026-06-09T06:21:13] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 0 (Closed)

[2026-06-09T22:05:39] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 (Open)

Bedroom occupancy sensor shows 0 occupancy at midnight, but does not explicitly rule out presence at 22:05 if motion detection has a delay or blind spots.

Rapid toggle between Manual Unlock (Type=1) and Auto Lock (Type=0) on the front door, specifically the pattern at 07:13 and 18:29 which suggests either malfunctioning logic or forced interaction attempts.

Correlation between Bedroom Window opening at 22:05:39 and Front Door Auto-Lock at 22:05:48 (within 9 seconds), suggesting coordinated access points.

Check for proximity sensor data or RFID tags associated with the door lock events to confirm if a human physically touched the handle vs. remote/auto trigger.

Verify the timestamp precision and gap between the window lift command and the door lock state change to determine causality.

Review the history of the smoke alarm battery alert to ensure it was resolved and did not cause a false low-power shutdown affecting other sensors.

Cross-reference with camera feeds (if available) for the entrance and bedroom areas during the timestamps 07:13, 18:29, and 22:05.
