疑似尾随入侵警报，建议住户确认是否有同行人

Suspicious sequence where an unknown user (ID=3) locked the front door, followed by occupants entering rooms and sequentially opening windows while occupancy sensors were active.

Explanation: Analysis of the raw log reveals a specific event at 18:27:00 where the front door was locked by 'UserIndex=3', which is not a standard resident identifier (unlike typical manual locks seen earlier in the day).

Explanation: Following this anomalous lock, occupants were detected in the master bedroom (20:54) and kids' room, leading to a sequential state change where both the kids' room window and master bedroom window were opened to full extent (10000/100ths) between 20:54 and 22:37.

Explanation: The combination of an unregistered user locking the perimeter, followed by internal window openings without corresponding motion sensor alarms or forced entry triggers, strongly indicates a staged intrusion attempt rather than normal household behavior.

Sequential window opening events: kids_room_window at 20:54:02 and master_bedroom_window at 22:37:14, both set to 100% openness.

Immediately contact local law enforcement with the timestamp of the suspicious lock event (18:27).

The presence of 'UserIndex=3' performing a manual lock operation is statistically rare for standard resident behavior patterns unless it's a specific family member not indexed as 1 or 2.

The clustering of suspicious window states with a specific non-standard lock event.

[2026-06-10T22:37:24] front_door_lock | DoorLock.LockState = 1

Check if UserIndex=3 corresponds to a registered family member, delivery personnel, or an unknown ID in the access control database.

Retrieve raw motion sensor logs for kids_room and master_bedroom immediately preceding and following the window state changes to detect stealth movement.

Verify the timestamp correlation between the front door lock state change and any external perimeter sensors (if available).

Check system logs for any IP address association with the cloud request that triggered UserIndex=3.

温度异常上升但无合理热源（空调关闭/制冷模式，灶具关闭） 上升速度超过正常烹饪或日照导致的范围

火灾风险警报，建议住户检查该区域电器

A significant fire hazard is indicated by a smoke alarm activation and rapidly rising temperatures in the living room during an unoccupied period, with no subsequent evacuation or sensor reset.

Explanation: Occupancy sensors confirm the house was completely empty (0) at 04:49 when the smoke alarm triggered.

Explanation: Temperature logs show a dangerous spike from ~2318°F (approx 1270°C - likely raw value scaling issue but indicates rapid heating trend) to 2435-2437 immediately surrounding the alarm event at 04:49, suggesting intense heat source rather than normal fluctuation.

Explanation: No occupancy events occurred after the alarm to indicate residents waking up and evacuating, implying either a delayed reaction or that the system failed to alert occupants effectively given the 'empty' state.

[2026-06-05T02:30:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2352

[2026-06-05T04:50:00] living_room_temp_sensor | TemperatureMeasurement.MeasuredValue = 2435

Immediately dispatch emergency services to the property location for fire inspection.

Instruct household members to perform a physical walk-through of the living room to check for lingering smoke, damage, or unsafe conditions before re-entering.

Reset the smoke detector only after a professional inspection confirms the cause and safety.

[2026-06-05T07:25:23] front_door_lock | DoorLock.LockState = 2

[2026-06-05T21:03:06] kids_room_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

[2026-06-05T22:36:21] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Standard household routine: Residents left home overnight (all rooms empty at 00:00), locked doors manually upon return, and automated locking engaged later.

Room activity distribution matches typical daily patterns (kitchen/living high day, entrance high evening)

Occupancy sensors show 0 across all rooms at 00:00:00

Door lock states change from Unlocked (1) to Locked (2) at 16:27 and 18:07

The specific timing of Auto-lock operations immediately following Manual locks suggests potential forced re-locking or system glitch rather than just passive automation

Smoke alarm activation is unexplained by this hypothesis

[2026-06-05T22:36:29] front_door_lock | DoorLock.LockState = 1

Check `living_room_smoke_alarm` logs for temperature spikes, CO levels, or image/video feeds around 04:49 to distinguish fire from cooking steam.

Verify `front_door_contact_sensor` status timeline: Was the door physically opened between 07:25:23 and 07:25:31? Check for gap in contact sensor data indicating door propping.

Inspect `kids_room_occupancy` and `master_bedroom_occupancy` logs between 06:19:15 and 22:36:21 to confirm if anyone was present to manipulate windows, or if it was external access.

Review system configuration logs for `front_door_lock` to determine if 'Auto' source is a legitimate smart-home feature or an injected command.

A confirmed fire alarm triggered in an unoccupied home following a continuous, abnormal temperature rise in the kitchen over several hours, indicating a potential cooking hazard or equipment failure.

Explanation: House occupancy sensors consistently reported zero occupants across all rooms from midnight until the incident.

Explanation: Kitchen temperature readings show a steady and significant increase starting at 00:00 (2263) and accelerating sharply to 2507 by 06:45, deviating from normal ambient fluctuations.

Explanation: The smoke alarm triggered exactly when the temperature peaked (06:46), confirming a physical safety event rather than just a sensor error.

[2026-06-28T06:45:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2507

Immediately dispatch emergency services to verify the presence of fire/smoke.

Send remote notification to the homeowner with specific details on the location and time of the alert.

If safe and automated protocols allow, remotely trigger the house ventilation system to attempt suppression if no active flame is detected yet.

Kitchen temperature sensor exhibits severe data drift and failure to return to baseline, indicating a hardware malfunction or calibration loss rather than an actual fire event.

Explanation: Temperature readings show a consistent, monotonic increase over several hours (2278°C at 00:00 rising to 2394°C at 04:00), which is physically impossible for ambient indoor air and indicates sensor drift/failure.

Explanation: At 18:52, the sensor jumped drastically to 2927°C while the smoke alarm explicitly reported 'SmokeState = 0', proving no combustion occurred despite the erroneous high reading.

Explanation: The absence of any occupancy changes or other environmental anomalies confirms this is an isolated sensor failure, not a real-world hazard.

kitchen_temp_sensor reading progression: 2273 -> 2394 over 4 hours (physically impossible)

kitchen_temp_sensor spike to 2927 followed immediately by SmokeState=0

Immediately replace the kitchen temperature sensor as it is providing false data.

Verify the sensor's physical integrity (check for dust blockage or electronic damage) before reinstalling.

Review system logs to understand why the security module (SQ5) flagged this specific sensor drift as a security anomaly instead of a maintenance alert.

The sheer volume of events (1492) is unusually high for a simple battery check; The system flagged this as a specific 'Security Anomaly' (SQ5) rather than a routine maintenance notification

High event density (1492 total, 81 focus) during non-peak hours

Check for any unauthorized MAC addresses or new device registrations appearing around 18:42 on 2026-06-26

Verify if the 'BatteryAlert' triggered any downstream automation rules that were not intended to run (e.g., locking doors, flashing lights)

Inspect the security module's internal state machine logs to see why a battery test resulted in an 'Anomaly' classification

Look for unusual network traffic spikes from the smart hub immediately preceding the 18:42 timestamp

High confidence that an unauthorized entry attempt or lock manipulation occurred at 07:46, evidenced by a manual lock being immediately reversed by an 'Auto' command while the door was physically open.

Explanation: The front door was manually locked at 07:46:20 (State=2) and contact sensor confirmed it closed.

Explanation: At 07:46:28, the contact sensor briefly flipped to False (open), indicating the door was opened.

Explanation: Immediately after (07:46:29), the system received an 'Auto' source command to unlock the door (LockOperationType=0, State=1), contradicting the user's manual action just seconds prior.

Explanation: This rapid sequence of Lock->Open->Unlock within 9 seconds strongly suggests physical tampering or a compromised smart lock acting on remote instructions during an intrusion attempt.

Immediately change the PIN/passwords for all smart home devices and the hub.

Force a factory reset on the front door lock if access codes are suspected to be compromised.

Contact local law enforcement to report a potential break-in attempt.

Review network logs for external IP connections to the smart lock IP address between 07:46:20 and 07:46:29.

Verify if the 'UserIndex=1' on the 18:10 manual lock operation corresponds to a known authorized user.

Review access logs for the smart home hub to see who triggered the 'Auto' unlock command at 07:46.

Cross-reference children_room_window opening event (20:59) with any app usage logs or cloud API calls from outside the local network.

Multiple indicators suggest a potential break-in attempt involving forced entry at the front door and unauthorized window manipulation in unoccupied rooms.

Explanation: Front door contact sensors toggled rapidly (False/True) immediately after manual locking attempts, indicating the door was physically forced open or probed while locked.

Explanation: Window coverings in the kids' room and master bedroom changed state to fully closed while occupancy sensors confirmed 'Empty' status, suggesting access via these windows or tampering with blinds from outside.

Explanation: The sequence of manual lock operations followed by rapid state changes deviates significantly from normal user behavior patterns.

Routine evening locking of the front door via automatic mechanism after occupants have left.

Occupancy sensors showing 0 for all rooms at 00:00:00.

Multiple earlier manual lock/unlock events within short intervals suggesting struggle or testing.

Simultaneous window state changes in unoccupied bedrooms.

Cluster of manual lock operations on front_door_lock between 07:47 and 18:05 followed by an auto-lock event at 22:25, with intermediate state inconsistencies.

Window covering position changes (0 -> 10000) in kids_room and master_bedroom occurring while occupancy sensors report 'Empty'.

Timestamped motion sensor logs for entrance hallway and living room immediately preceding the 07:47 and 18:05 front door events.

Audio log or vibration data from the front_door_lock device around the times of manual operations to detect forced entry sounds.

Detailed window contact sensor logs for kids_room and master_bedroom to confirm if windows were physically opened alongside curtain movements.

Global occupancy sensors are reporting a persistent '0' state across all rooms simultaneously while temperature data indicates active system operation and potential environmental changes, suggesting a systemic sensor or network synchronization failure rather than natural occupancy patterns.

Explanation: All monitored room occupancy sensors report '0' at identical timestamps (00:00, 00:30, 01:00, etc.) with perfect synchronization, which is statistically impossible for natural human movement but typical of a broadcast error or firmware glitch.

Explanation: Temperature logs show continuous readings (e.g., kitchen_temp_sensor values increasing from 2269 to 2399) indicating the devices are powered on and transmitting data, ruling out total power loss or complete device offline status.

Explanation: The simultaneous zero-value event contradicts the hypothesis of an intruder using motion avoidance techniques, as a person moving through the house would trigger sequential positive detections in adjacent rooms.

[2026-06-27T00:00:00] master_bedroom_occupancy | OccupancySensing.Occupancy = 0

Verify physical presence of residents via other means (video doorbell, phone calls) to rule out actual vacancy.

Check network connectivity and MQTT broker logs for packet drops or malformed messages between 00:00 and current time.

Attempt a remote reboot of the central hub or specific sensor clusters to reset the synchronized stuck state.

Temporarily disable automated alarms triggered by false negative occupancy until root cause is resolved.

Verify if the security module warning correlates with a specific network latency spike, power outage event, or cloud API timeout during the 00:00 - 01:00 window.

Cross-reference door lock logs to see if any entry/exit events occurred without triggering an occupancy change in the corresponding hallway or room sensors.

An unauthorized individual (UserIndex=8) gained entry through the front door at 22:03 and subsequently entered the children's room while window coverings were fully open, despite no prior occupancy detection in that specific room.

Explanation: The raw log confirms a LockOperation from 'OperationSource=8' (non-resident) immediately preceded by an Occupancy event at the entrance, indicating forced or unauthorized entry.

Explanation: Corroborating evidence shows the kids_room_window was set to 100% lift (fully open) at 21:13, followed 8 minutes later by occupancy detection in the kids_room at 21:14, suggesting entry via this vector.

Explanation: Standard security protocols show manual locking by residents at 07:45, 16:24, and 17:58, making the 22:03 event with an unknown source ID highly suspicious.

Immediately contact local law enforcement and provide them with the timestamp of the unauthorized access.

Dispatch security personnel or trusted neighbors to check the premises if safe to do so, otherwise await police arrival.

Secure all smart locks and reset any compromised credentials associated with UserIndex=8.

Review video footage from the front door and interior cameras between 22:00 and 22:30 for suspect identification.

Check raw access logs for 'front_door_lock' around 22:03 to identify if UserIndex=8 corresponds to a known guest, delivery service, or is a spoofed ID.

Verify video footage from 'kids_room' or adjacent living areas between 21:13 and 00:00 to confirm if anyone entered via the window.

Cross-reference 'kids_room_occupancy' sensor calibration logs to ensure the lack of detection before 00:00 was not due to sensor failure.

The lock operation at 19:49 was authorized (UserIndex=1), followed by a consistent transition to an empty house state, indicating normal departure and system arming.

Explanation: Lock event at 19:49 shows OperationSource=3 and UserIndex=1, indicating an authorized user action rather than unauthorized access or remote tampering.

Explanation: Front door contact state changed to False immediately after the lock command, confirming the door was properly closed and secured.

Explanation: Occupancy sensors reported zero for all rooms consistently from 00:00 onwards with no conflicting motion events, supporting the hypothesis of residents leaving for the night.

The front door was locked remotely from an unknown source (ID=3) at 18:31 while the house was unoccupied and no entry sensors were triggered prior to the lock event, suggesting a potential breach or forced entry scenario where the intruder gained access before the system could react.

Explanation: Occupancy logs confirm the home has been empty since at least 00:00 and specifically at 18:30, ruling out residents locking the door from inside.

Explanation: The lock operation at 18:31 originated from 'OperationSource=3', which is not a standard resident device ID in typical smart home configurations, indicating an unauthorized or automated external trigger.

Explanation: No preceding contact_sensor events on the entrance were recorded before the lock command, implying either the intruder bypassed the sensor or the system failed to detect physical interaction before the remote lock attempt.

Evidence indicates a forced entry via the kids' room window while the front door was securely locked and no residents were present.

Explanation: The kids' room window was opened to 100% at 21:03:10, exactly one minute after occupancy sensors confirmed residents were in the master bedroom but not the kids' room.

Explanation: No motion or occupancy events occurred in the kids' room between the window opening (21:03) and the next morning when the window was closed (06:41), suggesting unauthorized access rather than a resident action.

Explanation: The timing of the window opening (late night) combined with the subsequent lack of human activity until morning strongly contradicts the 'routine evening routine' hypothesis.

Potential unauthorized entry detected via a lock operation from an unknown source (UserIndex=3) immediately followed by the door contact sensor reporting an open state, while all internal occupancy sensors confirmed empty.

Explanation: The lock operation at 19:10:00 originated from 'OperationSource=3' and 'UserIndex=1', which contradicts typical primary user patterns for a secure departure given the system warning context.

Explanation: Crucially, the log shows the front door contact state changing to 'False' (open) just two seconds after the lock operation, indicating the door was physically manipulated or bypassed rather than simply locked.

Explanation: Simultaneously, all room occupancy sensors reported '0' (empty), creating a scenario where the house is vacant but the entry point is being actively tampered with or opened.

火灾风险警报，建议住户检查该区域电器

Evidence indicates a forced entry attempt at the front door involving manual manipulation of the lock, followed by a sensor bypass and immediate auto-relock.

Explanation: At 07:26:28, a manual lock operation occurred while the door contact sensor was still reporting 'Closed' (False), suggesting the door might have been propped open or forced without fully releasing the latch initially.

Explanation: Between 07:26:30 and 07:26:37, the front_door_contact sensor reported 'Open' (True) for 7 seconds, yet no occupancy was detected inside, indicating a potential tailgating event or an attempt to enter while the system thought the house was empty/locked.

Explanation: The sequence shows the door being manually manipulated, briefly opening, and then immediately triggering an automatic re-lock cycle at 07:26:38, which is characteristic of a security breach detection or forced entry failure.

Explanation: The high frequency of events at the entrance compared to other rooms further isolates this as the primary security concern.

[2026-06-26T07:26:30] front_door_contact | BooleanState.StateValue = False (Door Open)

Immediately review video surveillance footage for the timestamp range 07:26:28 - 07:26:45 to identify the intruder.

Inspect the physical front door hardware for signs of tampering, forced entry, or lock manipulation.

Check the battery voltage and torque logs of the front door lock motor to determine if the device malfunctioned during the event.

Verify with the homeowner regarding any legitimate visitors around 07:26 AM who may have caused the manual interaction.

Verify if the Living Room Smoke Alarm state was manually reset or triggered by environmental data (CO/Smoke ppm levels).

Cross-reference camera feeds (if available) with the timestamp 07:26:28-07:26:38 to see who/what performed the initial manual lock.

Check network traffic logs for any unauthorized API calls attempting to trigger the door lock between 07:26 and 22:50.

All observed events are consistent with normal household routines, including occupants entering/exiting and automated security protocols.

Explanation: The 'LockState=2' event at 07:27:25 is immediately followed by an explicit 'Manual' lock operation log at the same timestamp, resolving the apparent sequence gap as a logging artifact rather than an unauthorized action.

Explanation: Occupancy sensors confirm human presence in the entrance (07:27:28), dining room (16:13:08), and living room (20:52:10) exactly when door locks or window coverings change state, validating user-initiated actions.

Explanation: The late-night opening of curtains (20:52) correlates directly with the detection of occupancy in the living room shortly after, indicating an occupant manually adjusting the environment rather than an intruder.

[2026-06-22T07:27:28] entrance_occupancy | OccupancySensing.Occupancy = 1

[2026-06-22T20:52:10] living_room_occupancy | OccupancySensing.Occupancy = 1

Continue standard monitoring; no immediate intervention required.

Review system logs to clarify the definition of LockState values to prevent future alert fatigue regarding state transitions without intermediate unlock events.

Late-night opening of kids' room curtains when most rooms show 0 occupancy

Kids room window covering changing from Closed (0) to Fully Open (10000) at 20:52 while the house appears empty (all occupancy sensors 0)

Raw GPIO/I2C logs for the front door lock motor current spikes between 07:27:25 and 07:27:28 to detect if the lock was physically turned via external force rather than electronic unlock.

Network traffic logs for the `kids_room_window` device IP around 20:52 to verify if the command originated from a local controller or an external unknown source.

Motion sensor raw data for the hallway/entrance area between 07:27:28 and 16:14:00 to confirm if anyone entered during the unexplained lock state change.

Explanation: Immediately following the lock operation (18:32:02), the front_door_contact sensor registered 'False' (open), indicating the door was successfully opened after being unlocked.

Explanation: The systematic empty occupancy readings later in the night do not contradict this; they merely indicate no occupants were present during those specific intervals, but the breach occurred earlier.

[2026-06-13T18:32:02] front_door_contact | StateValue = False

Immediately change the PIN/code or credentials for the front door lock.

Review network logs to identify the device/IP address associated with OperationSource=3.

Temporarily disable remote access to the lock until the threat is mitigated.
