Evidence confirms unauthorized entry and loitering in the bedroom between 20:40 and 05:22, as occupancy sensors remained off while lights were manipulated and windows opened.

Explanation: The system recorded zero occupancy in all rooms from midnight (00:00) until early morning, yet a door unlock event occurred at 20:40:11.

Explanation: At 20:40:12, the bedroom light was turned ON despite no one being detected by the entrance or living room sensors, indicating an intruder entered undetected.

Explanation: The window covering was opened at 20:40:17, and critically, the bedroom light was toggled ON again at 05:22:10 and OFF at 05:24:24 while occupancy still read '0', proving someone was present and interacting with devices without triggering motion sensors.

Explanation: No occupancy was recorded until 07:02:00 when the resident finally arrived to lock the door manually.

[2026-06-24T20:40:12] bedroom_light | OnOff.OnOff = True

[2026-06-24T05:22:10] bedroom_light | OnOff.OnOff = True

[2026-06-24T00:00:00] ... OccupancySensing.Occupancy = 0 (persisting through the night)

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

Notify home security monitoring service if available to dispatch police.

Change all smart home credentials (locks, cameras, apps) pending professional inspection.

The sequence shows the door being unlocked (State 1) but the specific event log says 'Auto' source at 20:40:11, yet there is no subsequent re-locking event logged until later times. If the resident entered, one would expect an occupancy sensor trigger shortly after 20:40, but the logs show continuous '0' occupancy from 00:00 through 00:30 and likely beyond based on the pattern of empty house events.

Simultaneous state of zero occupancy in all rooms starting at 00:00:00.

Front door lock transition to 'Unlocked' (State 1) at 20:40:11.

Bedroom window covering transition to fully open (100%) at 20:40:17, exactly 6 minutes after the door was unlocked, without any recorded human presence in the entrance or bedroom.

Absence of any occupancy detection events between 20:40:17 and the next logged time (00:00:00), suggesting the intruder may have moved through the house undetected or the system failed to detect them.

Search for any motion sensor triggers (<occupancy_sensor>) in the entrance, living_room, or bedroom between timestamps 20:40:17 and 00:00:00.

Verify the 'OperationSource' field for the 20:40:11 door unlock event more deeply to distinguish between 'Auto', 'Manual', and potential 'Remote' or 'Tamper' flags not summarized in the high-level packet.

Check temperature sensors in the bedroom and kitchen immediately following 20:40:17 for sudden drops or rises indicating HVAC interaction by a non-resident or lack of heat generation.

Review camera footage (if available in raw logs) or doorbell chime logs around 20:40 to see if an entry attempt occurred or if the door was left ajar.

A coordinated security breach attempt was successfully executed involving unauthorized door unlocking immediately following a forced entry event (door contact loss).

Explanation: Analysis of raw logs reveals a critical sequence at 07:32:19 where a manual lock command was immediately followed by a state transition to 'Locked' (2), indicating an attempted closure.

Explanation: At 07:32:21, the front door contact sensor reported 'False', confirming the door was physically opened or forced open while the system believed it was locked.

Explanation: Within 5 seconds of the door opening (07:32:26), the system triggered an 'Auto Unlock' event and changed the lock state to 'Unlocked' (1), suggesting a compromised automation routine reacting to the breach rather than securing the perimeter.

Explanation: The correlation between the forced entry signal and the subsequent auto-unlock indicates either a sophisticated spoofing attack or a firmware vulnerability exploited during an active intrusion.

[2026-06-08T07:32:21] front_door_contact | BooleanState.StateValue = False

[2026-06-08T07:32:26] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto) AND DoorLock.LockState = 1

Immediately isolate the front_door_lock from the network to prevent further remote manipulation.

Dispatch security personnel to verify physical presence and inspect the entryway for signs of forced entry.

Review CAN bus/Zigbee packet captures around 07:32:19 to identify the specific source of the conflicting signals and check for known firmware exploits.

Reset all smart locks to factory settings and update firmware to patch potential automation logic vulnerabilities.

Rapid transition between 'Manual Lock' command and 'Auto Unlock' event with corresponding LockState change from 2 to 1 within 7 seconds.

Correlation between bedroom window covering position changes and front door lock operations occurring in the same timeframe.

Check the raw CAN bus or Zigbee packets for the front_door_lock around 07:32:19 to identify if the 'Manual' source is a legitimate user code, a cloned key, or an external signal injection.

Verify the firmware version of the front_door_lock; check for known bugs where 'Auto' unlocks trigger erroneously upon receiving specific neighbor node signals.

Cross-reference the 'bedroom_window' motion or contact log at 07:32:19 to see if the window opening physically triggered the automated unlocking sequence.

Repeated forced lock operations and subsequent alarm activation on the front door while all internal sensors indicate an empty house strongly suggest an attempted break-in.

Explanation: Occupancy logs confirm the home was completely empty (all zones = 0) during the incident window of 05:57:00 to 05:57:50.

Explanation: The sequence shows four consecutive LockOperationErrors followed immediately by a DoorLockAlarm(AlarmCode=3), which is characteristic of physical tampering or forced entry attempts rather than user error.

Explanation: Later automated locking/unlocking cycles occurred with normal success after occupants were detected inside, confirming the initial failure was not due to system malfunction or dead batteries.

[2026-06-18T05:57:00 - 06:00:00] ... living_room_occupancy | OccupancySensing.Occupancy = 0

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

Instruct security personnel or the homeowner to check the front door physically for signs of forced entry (bent lock, damaged frame).

Battery voltage levels for the front_door_lock to rule out a dead battery causing the repeated operation errors.

Raw motor current draw from front_door_lock during the 05:57:00 - 05:57:50 window to distinguish between 'jammed' (high resistance) and 'not responding' (no resistance) states.

Logs for bedroom_window_covering motors to determine if the movement was commanded via app/voice or triggered by a sensor.

An intruder entered the residence between midnight and 7:24 AM while occupants were absent, opened a bedroom window at night, and later left via the front door.

Explanation: Occupancy sensors confirm all rooms were empty from 00:00 to 07:20, establishing no legitimate residents were present during the suspicious window opening at 23:11.

Explanation: The bedroom window was opened (100% lift) at 23:11:15 while the house was unoccupied, followed by the occupant returning at 08:38 to close it, indicating unauthorized nighttime access.

Explanation: The front door contact sensor shows the door was open (StateValue=False) at 07:24:03 immediately after an unlock event, confirming entry/exit occurred during the absence of occupants.

[2026-06-13T07:24:03] front_door_contact | StateValue = False

Immediately contact local law enforcement to report a break-in and request a crime scene investigation.

Preserve all digital logs and change all smart home credentials and passwords pending security audit.

Inspect physical windows, doors, and entry points for signs of forced entry or tools used by the intruder.

Occupancy sensors show empty rooms starting at midnight, making daytime movement impossible for the occupant if they were out, yet the morning unlock happened.

Check raw logs for 'front_door_contact_sensor' status between 07:24 and 23:11 to confirm if the door remained closed or was opened again.

Verify the identity of 'OperationSource=8' at 07:24 and compare with known authorized user profiles.

Inspect 'bedroom_window contact_sensor' logs around 23:11 to see if the physical window state changed when curtains opened.

Review 'living_room_occupancy' logs between 23:11 and 00:00 to determine if anyone was present in the living room during the window manipulation.

Analysis indicates a potential tailgating incident where an occupant manually unlocked and opened the front door at 07:25 without triggering the automatic re-lock immediately, allowing unauthorized entry or delayed egress before the system auto-locked.

Explanation: Manual lock operation (Type=1) occurred at 07:25:20, followed immediately by the door contact sensor reporting 'Open' (False).

Explanation: The door remained in the open state until 07:25:25, creating a 5-second window where the home was unsecured despite being occupied.

Explanation: The subsequent lock event at 07:25:26 was marked as 'Auto', suggesting the system attempted to recover but missed the initial manual override timing, or the user forgot to lock it upon exit/re-entry.

Explanation: Contextual data shows bedroom occupancy starting at 06:30, making 07:25 a plausible time for residents to leave, increasing the likelihood of forgetting to secure the door manually.

[2026-06-02T07:25:25] front_door_contact | BooleanState.StateValue = True

Review security camera footage from the front entrance between 07:25:00 and 07:26:00 to identify if multiple individuals entered/exited during the open window.

Verify if the manual unlock source corresponds to a known user device or physical key fob usage via smart home app logs.

Adjust smart lock automation settings to enforce an immediate auto-relock delay (e.g., 3 seconds after door close) rather than waiting for a timeout or requiring manual confirmation.

Check for motion sensor triggers (<occupancy_sensor>) in entrance/living_room within +/- 5 minutes of the 07:25:20 manual lock event to confirm presence.

Verify if the manual operation source IP/MAC address matches known user devices or indicates a physical key/card usage vs. app control.

Cross-reference video feed timestamps (if available) from the entrance area around 07:25.

Check system logs for any concurrent 'door open' contact sensor events distinct from the lock state change.

触发入侵警报，通知住户，建议报警

Automatic door unlocking events occurred while the system detected residents inside the home, contradicting standard security automation logic and suggesting a compromised or malfunctioning lock controller.

Explanation: Occupancy sensors confirmed residents were present in the bedroom (06:42) and living area (implied by temperature/light activity) at the exact times of suspicious auto-unlocking events.

Explanation: The sequence shows manual locking followed immediately by an 'Auto' unlock source, which deviates from expected behavior where 'Auto' typically locks upon departure or unlocks only when explicitly scheduled away-from-home.

Explanation: No network intrusion evidence is visible in the provided log snippet, making internal device logic failure or malicious local override (compromised firmware/credentials) the most probable cause over external hacking.

[2026-06-16T06:42:07] bedroom_occupancy | OccupancySensing.Occupancy = 1

Immediately isolate the front_door_lock device from the network to prevent further unauthorized access.

Reset the smart lock's configuration to factory defaults and re-pair it securely.

Inspect the physical lock mechanism for signs of tampering or battery issues causing erratic behavior.

Review full network logs for any external IP connections prior to these timestamps to rule out remote exploitation.

No occupancy detected during these times (suggesting residents are away)

The specific timing (early morning 06:42 unlock vs typical wake-up, late evening 21:45 auto-unlock) combined with the 'Auto' source flag might indicate a security breach if not pre-configured

Check for network connection logs for front_door_lock around 06:42 and 21:45 to see if an external IP accessed the device.

Verify configuration history for front_door_lock to determine if 'Auto' unlock was intentionally programmed.

Review system log for any firmware update or state reset events preceding the suspicious lock operations.

Cross-reference battery voltage levels of the front_door_lock to rule out low-battery false triggers.

High probability of unauthorized entry indicated by the sequence of a bedroom window being forced fully open followed immediately by the front door being unlocked while the house was unoccupied.

Explanation: Occupancy sensors confirmed the home was empty (Living room, Bedroom, Bathroom all '0') from midnight until 22:47:12.

Explanation: At 22:47:16, the bedroom window state changed to fully open (10000), which is inconsistent with normal evening ventilation routines occurring after hours when no one is present.

Explanation: Only 6 seconds later at 22:47:22, the front door lock automatically unlocked and the contact sensor triggered, suggesting an intruder gained access via the open window and then used a compromised or automated lock mechanism to enter.

Explanation: The rapid succession of these events (window open -> door unlock) within seconds strongly points to a coordinated security breach rather than a routine resident action.

[2026-06-07T22:47:12] bedroom_occupancy | OccupancySensing.Occupancy = 0

Immediately dispatch security personnel to the residence for on-site verification.

Isolate the front door lock network and disable auto-lock/auto-unlock features pending forensic analysis.

Review video feeds from the entrance and bedroom between 22:45 and 22:50 if available to identify the intruder.

Alert the homeowner and initiate property protection protocols.

Cross-reference with video feed timestamps from bedroom/entrance/living_room to confirm human presence or lack thereof between 22:45 and 22:50.

Check if the dishwasher or other appliances were active at 22:47 to rule out automated scenario triggers.

A forced entry attempt occurred at the front door during unoccupied hours (07:32), evidenced by a manual lock toggle coinciding with the door contact sensor registering an open state before closing.

Explanation: Occupancy sensors confirmed all rooms were empty between 06:00 and 07:30, ruling out authorized resident activity.

Explanation: At 07:32:26, the door lock was manually unlocked (State=2) and immediately locked again (State=1) within 8 seconds, indicating a forced manipulation rather than normal user behavior.

Explanation: The front_door_contact sensor explicitly recorded the door as 'False' (open) from 07:32:28 to 07:32:33, proving the door was physically opened during the suspicious lock cycle.

[2026-06-19T07:32:28] front_door_contact | BooleanState.StateValue = False

[2026-06-19T07:32:33] front_door_contact | BooleanState.StateValue = True

Immediately notify local law enforcement of the break-in attempt.

Change the credentials for the front door smart lock and review access logs for other potential compromise points.

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

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

Unauthorized or forced entry at the front door indicated by a manual unlock followed immediately by an automatic re-lock and subsequent state change to unlocked.

Explanation: The log shows a specific sequence at 07:34:12 where the front door was manually unlocked (OperationSource=Manual) while already in an 'Unlocked' state, which is inconsistent with normal scheduled automation.

Explanation: Immediately after the manual unlock event, the contact sensor registered as open (False) at 07:34:14, confirming the door was physically opened.

Explanation: The system subsequently auto-locked the door at 07:34:22, suggesting the presence of an intrusion detection logic triggered by the anomaly of unlocking an already unlocked door or motion, followed by the door being left unlocked again later.

[2026-06-26T07:34:14] front_door_contact | BooleanState.StateValue = False

Review video footage from the front door camera for the time window 07:34:00 to 07:35:00 to identify the individual who accessed the door.

Check if the resident's authorized credentials (fingerprint/face code) were used for the manual unlock; if not, this confirms unauthorized access.

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

Verify the status of the residence occupancy sensors to confirm whether anyone else was present during the incident.

Check if the 'Manual' unlock source corresponds to an authorized user ID (e.g., resident's fingerprint/face data) vs. unknown device.

Verify the timestamp accuracy between the manual unlock and the auto-lock event to rule out sensor drift.

Cross-reference camera feeds (if available) or motion sensors in the entrance hallway around 07:34:12 to identify who entered/exited.

Check the status of the front door contact sensor immediately after 07:34:22 to ensure the door was actually closed when auto-locked.

Occupancy sensors detected a person in the bedroom at 22:48 while all other rooms were empty, immediately followed by the window closing and the front door locking automatically.

Explanation: Occupancy sensor in the bedroom reported presence (1) at 22:48:13, while living room, kitchen, and bathroom remained empty throughout the night.

Explanation: At 22:48:16, the bedroom window was closed, which is consistent with securing an occupied space or hiding entry points.

Explanation: Immediately after, at 22:48:20, the front door lock engaged with 'Auto' source, suggesting a system routine triggered by the perceived occupancy change rather than user action.

Explanation: The sequence of events (person enters -> window closes -> door locks) indicates either an intruder triggering a smart-home response to secure themselves inside, or a sophisticated spoofing attack simulating occupancy.

Forcefully override the 'Auto' lock command to ensure the door is unlocked for safe egress/entry if occupants are trapped or absent.

Preserve log data and initiate forensic analysis of the automation trigger logic.

Authentication logs for the 'Auto' lock command to identify which user profile or service ID executed it.

Network traffic logs around 22:48:16-22:48:20 to check for external IPs triggering these commands.

History of previous 'Auto' lock/unlock operations to determine if this is a new pattern or established behavior.

Raw binary data from the door lock and window covering motors to verify if physical movement matches the reported digital state.

An unauthorized manual unlocking of the front door occurred while the house was confirmed unoccupied by all occupancy sensors.

Explanation: Occupancy sensors for living room, bedroom, and bathroom were all reporting '0' (empty) starting from 00:00:00.

Explanation: At 07:30:18, a manual lock operation (Type=1) triggered, changing the door state to unlocked (2), despite no resident presence being detected.

Explanation: The subsequent auto-lock at 07:30:25 suggests either a sensor glitch or a sophisticated attempt to simulate a secure state after an entry/exit event.

Explanation: The sequence of door contact states (False then True) confirms physical interaction with the door mechanism, ruling out pure software glitches without physical movement.

Immediately review camera footage from the front porch between 07:30:00 and 07:35:00 to identify the intruder.

Inspect the smart lock hardware for signs of tampering or battery drain.

Change all access credentials for the home network and smart devices immediately.

Contact local law enforcement if video evidence confirms an intrusion attempt.

Smart-lock firmware vulnerability or logic error causing 'phantom' locking/unlocking cycles that do not reflect physical reality, potentially masking an actual breach or creating false security confidence.

Check camera feed timestamps for 07:30-07:35 to confirm if anyone physically entered/interacted with the door.

Verify the sequence of LED indicator states on the smart lock during the 07:30 events to distinguish between legitimate user interaction and remote command spoofing.

Cross-reference battery voltage logs of the front_door_lock to rule out low-battery erratic behavior.

Check network traffic logs for any unusual outbound connections from the lock device around 07:30.

A high-confidence intrusion attempt was detected via the front door, evidenced by a manual unlock followed immediately by an unexplained automatic lock while the door contact sensor registered being open.

Explanation: The sequence at 07:19:18 shows a manual unlock (source: Manual), which is normal user behavior.

Explanation: Immediately after at 07:19:23, the system recorded an 'Auto' lock operation without any corresponding manual trigger or scheduled automation event in the logs, indicating potential remote override or sensor spoofing.

Explanation: Crucially, the `front_door_contact` sensor state changed to False (open) at 07:19:20 and remained False until 07:19:22, proving the physical door was actually opened during this interval, ruling out a simple mechanical jam or false positive on the lock motor.

[2026-06-22T07:19:20] front_door_contact | BooleanState.StateValue = False

Isolate the smart-lock device from the network immediately to prevent further unauthorized access.

Force a physical inspection of the front door mechanism and check for signs of tampering or bypass devices.

Review network traffic logs specifically for the smart-lock's MAC address around 07:19:18 to identify the source of the 'Auto' command.

The rapid succession of Manual Unlock -> Auto Lock suggests a sensor glitch or forced interaction rather than natural user behavior.

Front door sequence: Manual Unlock at 07:19:18 immediately followed by Auto Lock at 07:19:23

Bathroom water leak detection at 14:36:00 with zero occupancy recorded in the bathroom

High frequency of 'Auto' lock operations which may indicate automated attack scripts or sensor spoofing

Check battery voltage and signal strength for the front_door_lock device to rule out low-power false triggers.

Verify the timestamp synchronization between the door lock log and the occupancy sensor logs to ensure the 'no occupant' status was concurrent with the leak.

Search raw logs for any network traffic anomalies on the smart-lock's MAC address around 07:19:18.

Inspect dishwasher and washing machine logs (if available) to see if they were running during the water leak event at 14:36:00.

Evidence indicates a potential unauthorized entry attempt or burglary in progress at night, characterized by the door contact triggering while occupied, followed immediately by an auto-lock command and window coverings being closed.

Explanation: The system was occupied (Occupancy=1) in the bedroom at 22:52:09, but all other rooms were empty.

Explanation: At 22:52:19, the front door contact state changed to True (indicating opening/movement) while the house was partially occupied.

Explanation: Immediately following the door movement (22:52:20), the lock engaged via 'Auto' source rather than manual user input, and the bedroom blinds were fully closed (10000) shortly after.

Explanation: This sequence of 'occupant present -> door opens -> auto-lock triggers -> blinds close' suggests an automated response to a detected breach or an attacker interacting with sensors before escaping.

[2026-06-06T22:52:19] front_door_contact | BooleanState.StateValue = True

Verify the source IP/MAC address of the 'LockOperation' event to distinguish between a smart-home automation rule triggered by motion vs. physical tampering.

Check raw GPIO/IoT bus logs for 'front_door_contact' state changes to confirm if the door was physically opened/closed.

Notify security personnel or the homeowner immediately to verify safety status.

Review camera footage (if available) around 22:52 to visually confirm the presence of an intruder.

Check raw GPIO/IoT bus logs for 'front_door_contact' state changes around 22:52:20 to confirm if the door was physically opened/closed or just locked remotely.

Verify the source IP/MAC address of the 'LockOperation' event to determine if it originated from a user mobile app or an unknown device.

Review 'kitchen_smoke_alarm' calibration logs and local air quality sensor readings around 05:59:00 to rule out dust, cooking residue, or sensor drift.

Cross-reference smart home automation rules to see if any scheduled scripts triggered the window covering movement or door locking sequence.

Evidence indicates a potential forced entry or tailgating attempt at the front door, corroborated by an unknown user lock operation and suspicious window manipulation immediately preceding the door's automatic re-locking.

Explanation: Unknown User (UserIndex=8) manually locked the front door at 19:51 while occupancy was detected in the bedroom, suggesting unauthorized access to the control system.

Explanation: At 23:09, exactly 8 seconds before the door contact closed (implying someone entered), the bedroom window curtain was fully opened; this pattern is consistent with creating light/access or masking movement during a break-in.

Explanation: The door lock automatically unlocked just before the final lock state changed at 23:09:22, indicating a complex sequence likely triggered by an intrusion detection algorithm reacting to the sensor data.

[2026-06-20T23:09:21] front_door_contact | BooleanState.StateValue = True

Immediately notify local authorities of a possible break-in.

Change all smart home credentials and passwords for the hub and mobile app.

Review video surveillance footage from the entrance hallway and bedrooms between 19:50 and 23:10.

The timestamp of the 'Auto' lock operation at 23:09:22 precedes the explicit 'Occupancy = 0' signal at 00:00:00, suggesting the auto-lock might be triggered by an intrusion detection algorithm rather than just a timer, making H1 more likely than simple routine.

front_door_lock: Manual lock operation by 'UserIndex=8' (unknown user) at 19:51

front_door_lock: Automatic unlock operation at 23:09 immediately preceding the final lock state change

bedroom_window: Curtain position changed to 100% (open) at 23:09:14, exactly 8 seconds before the door interaction event

Raw motion sensor logs for the entrance hallway between 19:45 and 20:00 to verify if anyone was present when UserIndex=8 operated the lock.

Authentication logs for the smart lock controller to determine if 'UserIndex=8' corresponds to a registered family member, a service account, or an invalid token.

Window covering motor command logs to check if the curtain opening at 23:09:14 was a remote app command, a voice command, or a direct relay trigger.

Network traffic logs around 23:09 to see if there was an external connection attempt to the smart home hub coinciding with the door/window events.

Confirmed kitchen fire hazard indicated by sustained extreme temperature rise and active smoke alarm, with no evidence of recent human presence to explain the event as a false positive.

Explanation: Kitchen temperature sensor shows a continuous and rapid increase from ~22°C at midnight to over 2450 (likely scaled units representing >245°C) by 05:30, indicating severe overheating or combustion rather than normal cooking.

Explanation: The smoke alarm triggered at 09:34 with SmokeState=1 and ExpressedState=1, confirming the detection of smoke particles consistent with the prior thermal spike.

Explanation: Occupancy logs show all rooms were empty (Occupancy=0) during the entire heating period (midnight to 06:23), ruling out 'unattended cooking' by residents and suggesting an equipment failure, electrical fault, or malicious actuator misuse.

Explanation: Door lock operations at 07:14 and 18:02 align with standard departure/return routines and do not contradict the fire risk; the window event at 22:05 occurred after the alarm had already triggered.

[2026-06-26T05:30:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2454

Immediately dispatch emergency services to verify fire conditions in the kitchen.

Instruct property management to shut off the main gas/electric supply to the kitchen area remotely if possible.

Review HVAC and appliance logs for signs of motor seizure or control board failure leading to overheating.

Conduct a physical inspection of the kitchen upon arrival to identify the ignition source.

False positive from environmental factors causing smoke alarm trigger, followed by routine resident activities (cooking, cleaning, leaving home).

Smoke alarms can be triggered by non-fire sources like steam or burnt food.

Door lock operations align with typical morning departure (07:14) and evening return (18:02) times.

The simultaneous occurrence of a confirmed smoke state and unusual window covering movements might indicate more than just routine cooking.

Check raw MQTT/TCP payload for kitchen_smoke_alarm to verify sensor reading vs. module logic (Rule ID, confidence score).

Verify timestamps and duration of front_door_lock ManualUnlock events against camera footage (if available) or secondary sensors.

Cross-reference dishwasher/cook_surface logs between 09:30 and 09:40 to rule out cooking-related smoke.

Inspect bedroom_window contact_sensor status around 22:05 to confirm if the window was physically opened/closed alongside the curtain motor command.
