The system alarm was triggered by a sensor drift issue (temperature reading 2398°C) rather than an intrusion or security breach.

Explanation: Occupancy sensors consistently reported '0' (empty) between 00:00 and 07:04, which was contradicted by the resident's confirmed presence via light activation, window opening, and manual door locking at 00:15-00:30 and 07:04, indicating occupancy sensor calibration drift or false negatives during early morning hours.

Explanation: Critical temperature readings in the kitchen and living room showed values over 2000°C (e.g., 2398, 2425, 2533), which is physically impossible for a residential environment and indicates a sensor malfunction or data corruption, not a fire event.

Explanation: The sequence of events regarding windows and doors shows logical human behavior: the resident opened curtains/blinds upon waking (05:23), locked the front door manually when leaving (07:04), and later returned to adjust settings (12:34, 13:50, 20:52). There are no signs of forced entry or unauthorized access.

Explanation: The specific trigger mentioned in Stage-1 analysis (bedroom window position change at 13:50) occurred concurrently with the resident being present in the kitchen and entrance, confirming it was authorized activity.

[2026-06-29T20:52:09] front_door_contact | BooleanState.StateValue = True followed immediately by lock disengagement and re-engagement patterns consistent with normal exit/entry.

TemperatureSensor logs showing values >2000 (e.g., 2398) alongside normal occupancy patterns, proving sensor failure rather than environmental hazard.

Resident interaction logs: Manual door lock operation at 07:04:09 and 08:40:00 confirm authorized control of the home perimeter.

Replace or recalibrate the kitchen and living room temperature sensors immediately due to critical readout errors.

Review occupancy sensor firmware or placement if false 'empty' states persist during low-light morning hours.

Acknowledge and clear the security alert as a false positive caused by hardware malfunction.

Check for motion sensor triggers on the bedroom window contact sensor around 13:50 and 20:52.

Verify if the front door contact sensor reported 'Open' state at any point between 07:04 and 13:50.

Cross-reference camera footage (if available) for the entrance and bedroom windows between 00:00 and 08:40 to confirm absence of persons.

Check system logs for any automated override commands sent to the window covering motor.

Unauthorized lock operation from an unknown source (UserIndex=8) at 23:30 coincides with a resident being present in the kitchen, indicating a potential break-in attempt or compromised access control.

Explanation: The log shows a LockOperation at 23:30 with OperationSource='8', which is inconsistent with standard user indices seen throughout the day (Manual/Auto).

Explanation: Crucially, OccupancySensing.Occupancy=1 was recorded in the kitchen at 23:30:00, proving the resident was inside while the external/unusual lock command occurred.

Explanation: This contradicts the hypothesis of total house vacancy and suggests an active intrusion attempt during occupancy or a sophisticated spoofing attack.

[2026-06-24T23:30:00] kitchen_occupancy | OccupancySensing.Occupancy = 1

Immediately verify the physical state of the front door via live camera feeds.

Contact local law enforcement to report a potential security breach.

Temporarily disable remote lock controls and require physical key verification for all subsequent operations.

Check raw network packets for the front_door_lock event at 23:30 to determine if UserIndex=8 corresponds to a known device ID (e.g., neighbor's sensor) or an unknown MAC/IP address.

Verify the source IP of the 'Auto' lock/unlock operations around 07:03 and 20:43 to rule out automated script attacks.

Cross-reference bedroom_window actuator logs with motor current draw to detect if the blinds were physically cut/moved vs. electronically commanded.

Review camera footage (if available) or motion sensor history between 20:00 and 00:00 to confirm no human presence despite occupancy sensors reading 0.

触发入侵警报，通知住户，记录事件

The front door lock exhibits erratic behavior by unlocking automatically immediately after a manual lock operation, indicating a firmware glitch or hardware failure rather than unauthorized access.

Explanation: At 06:51:10, the user manually locked the front door (LockOperationType=1), but at 06:51:13, the system automatically unlocked it (LockOperationType=0) despite the door contact sensor still showing 'False' (door closed) until 06:51:12. This contradicts normal security logic where a closed door should remain locked.

Explanation: The sequence suggests the lock controller failed to maintain the latched state, likely due to software instability or mechanical wear, rather than an intruder forcing entry which would typically show prolonged struggle events or different sensor readings.

Explanation: While occupancy sensors showed zeros during early morning hours, these were followed by a clear window opening event at 02:42 and subsequent occupancy detection, confirming they represent temporary sensor drift or calibration issues, not a primary threat.

[2026-06-24T06:51:12] front_door_contact | BooleanState.StateValue = False

Immediately check the physical status of the front door lock mechanism for damage or obstruction.

Update the smart lock firmware or reset the device to factory settings to rule out a software bug.

Replace the lock battery if voltage is low, as power fluctuations can cause state retention failures.

Systematic false zero-reporting: All occupancy sensors across every room reported '0' (empty) simultaneously at midnight and 00:30 AM. For an elderly person living alone, this contradicts expected sleeping patterns where at least one room should be occupied.

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

Timestamps of motion sensor triggers relative to the front door lock operations to determine if someone entered before the auto-unlock.

Battery levels and firmware version of the front_door_lock module to rule out hardware failure causing erratic locking states.

Raw IR data or confidence scores from all occupancy sensors around 00:00 and 00:30 to verify if they were truly empty or experiencing sensor calibration drift.

Video feed timestamps from any indoor cameras if available, cross-referencing with the curtain movement times.

A forced entry attempt at the front door was confirmed by a manual lock operation followed immediately by an unauthorized auto-unlock event, coupled with door contact sensor toggling indicating physical manipulation.

Explanation: Manual locking occurred at 06:59:08, followed 11 seconds later by an 'Auto' unlock event at 06:59:19 while no authorized automation schedule is evident in the logs.

Explanation: Door contact sensors show the door state changing to open (False) at 06:59:10 and returning to closed (True) at 06:59:18, confirming physical interaction coinciding with the lock cycle.

Explanation: The house occupancy data confirms the home was unoccupied during this window (all zones reported Occupancy=0 from midnight until 08:33), ruling out normal resident activity.

Contact local law enforcement immediately to file a report regarding the attempted break-in.

Notify the homeowner of the security breach and advise them to change all access credentials (keys, codes, smart locks).

Dispatch a security technician or locksmith to inspect the front door mechanism for signs of tampering or forced entry damage.

Evidence of a forced entry attempt at the front door followed by interior window manipulation to create an escape route or surveillance access.

Explanation: The front door lock was manually locked at 06:58:09, but the contact sensor immediately reported the door opening (False) at 06:58:11, indicating physical bypass or forced opening despite the lock command.

Explanation: The system triggered an 'Auto' unlock event at 06:58:17 while the door was still open, suggesting an automated response to the intrusion rather than a user action.

Explanation: A strong correlation exists between the intrusion event and subsequent suspicious activities: bedroom windows were opened shortly after the first incident (12:40) and again with lights turning on during the evening anomaly (20:41), consistent with establishing an egress path or staging area.

Log sequence showing LockState=2 (Locked) followed by ContactSensor=False (Door Open) within seconds without a manual unlock event in between.

Temporal correlation between the front door breach at 06:58 and the bedroom window being opened at 12:40 and 20:41.

Immediately dispatch law enforcement to the premises for investigation.

Isolate the smart home network and disable all actuators to prevent further remote manipulation.

Preserve raw logs and video footage from entrance and bedroom cameras for forensic analysis.

Window covering adjustments occurring during daylight hours (12:40 closed, 14:08 opened).

Rapid toggle of front door lock state within seconds (06:58:09 to 06:58:17) is inconsistent with normal usage patterns.

High frequency of events (1854 total, 60 salient) suggests system stress or repeated triggering beyond routine.

Correlation between specific door unlock events and subsequent window state changes.

Front door lock rapid state transition (Locked->Unlocked) triggered by 'Auto' source immediately after a 'Manual' operation at 06:58.

Bedroom window state change (Closed -> Open) occurring shortly after the front door was unlocked.

Repeated cycling of front door lock states at 20:41 coinciding with another bedroom window opening event.

Raw timestamps and duration of the front door lock physical interaction (did it take >5 seconds to unlock?).

Sensor data for the front door contact sensor during the 06:58 sequence to confirm if the door actually moved/opened.

Audio logs or camera feeds from the entrance and bedroom corridors around 06:58 and 20:41.

Network traffic logs to check for remote commands originating from unknown IP addresses triggering the 'Auto' lock operations.

Power consumption spikes on the smart lock controller during the anomaly window.

中等可信度警报，建议住户确认是否本人操作

The smart lock is exhibiting erratic behavior with rapid state toggling and an unrecognized source code ('8') interacting during occupied hours, indicating a hardware or firmware fault rather than human intrusion.

Explanation: Occupancy sensors confirm residents were present in the bedroom and entrance at 11:46, ruling out an unauthorized entry attempt by an intruder.

Explanation: The log shows rapid 'Lock->Unlock' cycles (e.g., at 07:08 and 08:26) occurring within seconds, which is inconsistent with standard manual operation and suggests mechanical jamming or software loop issues.

Explanation: The event at 11:46 uses an unknown 'OperationSource=8', which correlates with the anomalous cycling pattern, pointing to a device malfunction or corrupted authentication token rather than a new user profile.

[2026-06-16T07:08:07] front_door_contact | BooleanState.StateValue = False followed immediately by True

Occupancy logs showing presence in Bedroom and Entrance concurrent with the lock events

Immediately isolate the smart lock from the network to prevent potential automated abuse if the glitch persists.

Perform a physical inspection of the lock mechanism for obstructions or battery failure.

Reset the lock's firmware or replace the unit if the erratic toggling continues after a reboot.

Authentication logs for UserIndex=1 to determine if 'Source 8' corresponds to a known app, third-party service, or unknown device.

Motion sensor raw data timestamps around 11:46 to see if motion was detected before or after the lock interaction.

Door contact sensor status history immediately preceding the 11:46 lock event to confirm if the door was actually opened physically or digitally unlocked while closed.

An unauthorized entry occurred via the front door using a remote key (Source=8) at 14:40, immediately followed by occupancy detection in the entrance area, while the house was previously unoccupied.

Explanation: The raw log confirms a 'LockOperation' with OperationSource=8 (Remote Key) at 14:40:00, which contradicts standard manual or automatic operations seen earlier.

Explanation: Immediately after this lock operation at 14:40:03, the 'entrance_occupancy' sensor registered an occupancy event (Value=1), confirming physical presence inside the home following the unlock.

Explanation: Prior to 14:40, all room occupancy sensors reported 0 for hours, indicating the house was empty and the resident was likely out, ruling out routine cleaning scenarios.

[2026-06-15T14:40:03] entrance_occupancy | OccupancySensing.Occupancy = 1

Notify local authorities immediately regarding a potential break-in.

Do not enter the property; wait for law enforcement.

Remotely lock all doors and windows via the smart-home app if access is available from outside.

Preserve system logs and camera footage for forensic analysis.

Rapid curtain toggling pattern suggests observation rather than privacy adjustment

LockOperation via Source=8 (Remote Key) on front door

Repeated rapid state changes of bedroom window covering (0 -> 10000 -> 0 -> 10000)

Timestamps and duration of each curtain movement event relative to external camera feeds (if available) or nearby motion sensors to verify if someone was looking in/out.

Authentication tokens or MAC addresses associated with OperationSource=8 to determine if it belongs to a known authorized device or an unknown IoT botnet/device.

Check if the front door contact sensor registered an 'Open' state immediately after the Source=8 lock operation to confirm physical entry occurred versus just unlocking from outside.

The log sequence indicates a coordinated unauthorized entry event where an intruder entered via the front door and subsequently accessed the bedroom through the window to bypass interior detection or cover tracks.

Explanation: Occupancy logs show zero residents present from 00:00 until 07:10, yet manual lock/unlock cycles occurred at 07:10 and 08:21 without prior occupancy spikes indicating a resident's presence.

Explanation: A critical gap exists between the bedroom window being closed/opened at 05:20 and the first door interaction at 07:10; during this window, the bedroom light was ON while the room was unoccupied, suggesting someone manipulated the window remotely or via physical access before entering the main living area.

Explanation: The rapid succession of events (Door Lock -> Door Contact Open/Closed -> Auto Lock) followed by a return to 'Locked' state within seconds is characteristic of forced entry testing or tailgating rather than routine user behavior.

Immediately dispatch emergency services/police to the residence for on-site investigation.

Isolate and disable the smart home network connection to prevent further remote manipulation or data exfiltration.

Preserve raw video footage from entrance and bedroom cameras specifically between 05:00 and 09:00.

Access control logs for the front door to determine if the manual unlock was authorized via app/fingerprint or physical key insertion.

Video feed timestamps from the entrance hallway and bedroom window area around 07:10 and 14:00 to verify presence of persons.

Motion sensor raw data (not just occupancy flags) near the front door and bedroom window to detect approach vectors.

Smartphone/app location history to see if the resident was actually present inside or had left before 07:10.

Timestamps of other device activations (lights, curtains) relative to the door/window events to establish a timeline of actor movement.

Front door lock operations were confirmed to be performed manually by residents with corresponding occupancy and environmental activity data.

Explanation: Occupancy sensors show active presence in the bedroom at 06:53 and kitchen at 08:24 immediately preceding the manual lock events, confirming resident presence.

Explanation: The sequence shows a standard 'unlock -> open (contact opens) -> close -> auto-lock' pattern consistent with human entry/exit rather than forced intrusion.

A manual unlock event at the front door was immediately followed by an automatic re-lock while the door contact sensor indicated the door was open, suggesting a potential forced entry or tailgating attempt that failed.

Explanation: The log shows a specific sequence: Manual Unlock (06:53:10) -> Door Contact Open (06:53:12) -> Auto Lock Engage (06:53:20).

Explanation: The 'Auto' source triggering a lock command within 8 seconds of the manual unlock, combined with the door being physically open during this interval, deviates from standard resident behavior (which typically involves closing and locking manually or via app after entry/exit).

Explanation: While other logs show normal occupancy patterns later in the day, the isolated nature of this rapid cycle at 06:53, occurring before general household activity starts, points to an external anomaly rather than routine movement.

[2026-06-12T06:53:12] front_door_contact | BooleanState.StateValue = False

Review video footage from the front door camera for the 06:53:00 - 06:54:00 window to identify any individuals present.

Check physical locks and door hinges for signs of tampering or forced entry.

Temporarily adjust smart lock settings to require explicit user confirmation for auto-relock functions if not already enabled.

Verify if the 'Auto' source is a genuine sensor trigger (e.g., contact sensor detecting closure) or a system command anomaly.

Cross-reference bathroom and kitchen occupancy logs around 06:53 to rule out legitimate resident movement patterns.

中等可信度警报，建议住户确认是否本人操作

The smart door lock exhibits a critical failure where it reports an 'Auto' unlock command and changes state to 'Unlocked' immediately after a manual lock operation, while the physical contact sensor subsequently confirms the door is open without any recorded motor actuation or user presence in the hallway, indicating the device logic is overriding the physical lock mechanism.

Explanation: At 06:54:10, a manual lock operation occurred (LockState=2), but at 06:54:19, an 'Auto' source triggered an unlock event (LockState=1) within 9 seconds without any corresponding network traffic logs for remote commands or occupancy sensors detecting someone nearby.

Explanation: Crucially, the raw log shows the front_door_contact sensor went from False (open) to True (closed) at 06:54:18, implying the door was physically closed or the sensor glitched, yet the lock reported being unlocked immediately after. This disconnect between the 'Auto' unlock command and the lack of physical interaction evidence suggests the lock's firmware failed to execute the lock cycle or falsely reported its state.

Explanation: The repeated pattern at 20:40:14 mirrors the earlier incident: an 'Auto' unlock command occurs when no one is present (occupancy 0) and no entry motion is detected, confirming this is a systemic malfunction rather than a single-time anomaly or intrusion attempt.

Event at 06:54:19: LockOperation(LockOperationType=0, OperationSource=Auto) immediately followed by DoorLock.LockState = 1, despite no prior 'Unlock' command from a user or app.

Absence of entrance_occupancy events between 06:54:10 and 06:54:19, ruling out legitimate tailgating or forced entry requiring human presence.

Immediately disable the automatic locking/unlocking feature on the smart lock via the mobile app or control panel to prevent further unauthorized state changes.

Schedule an urgent technician visit to inspect the lock's internal battery, firmware integrity, and mechanical connection to the strike plate, as the device appears to be sending false status updates.

The discrepancy between 'Auto' unlock events and the physical state changing to Unlocked (1) in rapid succession suggests potential automation failure or external override.

Discrepancy between LockOperation Source='Auto' and subsequent LockState change from 2 (Locked) to 1 (Unlocked) within seconds, indicating possible unauthorized remote unlock or sensor glitch.

Repeated pattern of LockState toggling (2->1->2->1) at different times of day without clear manual intervention logs for the unlocking phase.

Timestamps of raw motor current draw on the door lock to detect if it was physically forced or rotated electronically.

Network traffic logs for the smart lock device around 06:54:10 and 20:40:14 to check for unauthorized access attempts or spoofed commands.

Battery voltage and firmware version of the front door lock to rule out malfunction causing false state reports.

Motion sensor data near the entrance hallway specifically between 06:54:10 and 06:54:20 to confirm if anyone entered physically.

An automated system triggered a sequence of unlocking the front door and opening the bedroom window while the house was unoccupied, indicating a potential breach or malicious automation hijack.

Explanation: Occupancy sensors confirmed all areas were empty (0) for several hours prior to the critical events at 20:55.

Explanation: The front door lock received an 'Auto' unlock command (OperationSource=Auto) at 20:55:11, immediately followed by the window opening at 20:55:29.

Explanation: This contrasts with normal behavior where manual operations occur during occupancy or specific routines, and no motion was detected in the entrance before the event.

Explanation: The kitchen smoke alarm triggered earlier at 19:07 but cleared quickly; the subsequent automated door/window actions are inconsistent with a standard fire safety response protocol which would typically seal rooms or alert occupants, not open them.

[2026-06-19T20:55:10] entrance_occupancy | OccupancySensing.Occupancy = 0

Immediately dispatch security personnel to verify physical entry status and secure premises.

Audit smart home hub logs to identify the source of the 'Auto' trigger and isolate compromised devices.

Reset all smart locks and change credentials to prevent further unauthorized access via automation.

Review camera feeds if available to confirm physical state of the door and window between 20:55:10 and 20:55:30.

Check kitchen smoke alarm logs around 19:07 to ensure it was a false positive or cleared before any potential breach.

触发入侵警报，通知住户，记录事件

Evidence indicates an unauthorized entry attempt at the front door followed by suspicious manipulation of the bedroom window while occupancy sensors recorded empty zones during critical lock state changes.

Explanation: The log shows a sequence where a Manual Lock Attempt (06:54:05) was immediately overridden by an Auto Unlock (06:54:08), suggesting an external force or tampering rather than user intent.

Explanation: Occupancy sensors in the entrance and living room registered '1' (presence) at 06:54:08, yet subsequent manual lock attempts at 08:27:00 occurred without corresponding occupancy data, implying potential sensor blind spots or stealthy movement.

Explanation: The bedroom window covering was manipulated to fully open (10000) at 13:51:09 when the bedroom occupancy sensor still reported '0', indicating a discrepancy between human presence detection and physical access points being altered.

[2026-06-27T13:51:09] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 0

Immediately contact local law enforcement to report a suspected break-in based on the locked/unlocked door cycle and window manipulation.

Secure all smart home devices remotely and change default passwords/API keys pending a forensic review.

Dispatch a security team to physically inspect the front door mechanism for signs of forced entry and verify the status of the bedroom window.

Sequence: Manual Lock Attempt -> Immediate Auto Lock State Change -> Window Covering Opened

Zero occupancy readings across all zones during active security events

Timestamps of motion sensor activations relative to the door lock operations to confirm if anyone entered.

Camera footage from entrance and bedroom windows for visual confirmation of human presence.

Power consumption spikes associated with the door lock motor during the 'Manual' operation timestamps.

Network connection logs for the front_door_lock device to check for unusual IP sources or repeated failed authentication attempts prior to the lock operations.

Multiple instances of manual front door unlocking occurred while the entire house's occupancy sensors reported zero presence, indicating an entry event where no resident was detected.

Explanation: Occupancy sensors across all rooms (kitchen, living room, bedroom, bathroom, entrance) consistently reported '0' from midnight until early morning activity resumed around 02:30 and later at 12:29.

Explanation: At 06:57:02 and 08:29:00, the front door lock log shows manual unlock operations (OperationSource=Manual), yet there is no corresponding occupancy detection in any room at those specific timestamps or immediately prior.

Explanation: The door contact sensor toggled to False (open) during these events without any human presence signal, suggesting either a person entered silently (bypassing sensors) or an external actor manipulated the lock.

[2026-06-11T00:00:00] ... entrance_occupancy | OccupancySensing.Occupancy = 0

Immediately verify physical security status of the property via remote camera feeds or on-site inspection if safe.

Check battery levels and calibration status of all motion/PIR sensors to rule out total system failure causing false negatives.

Review historical access logs for key fob usage or smart-lock app activity between 06:57 and 08:30 to identify unauthorized credentials.

System alerts were triggered by a near-miss lock event (resident present but door opened) and a delayed water leak sensor activation after the bathroom was vacated, with no evidence of intrusion or active leaks.

Explanation: Occupancy logs confirm a resident was present in the bedroom at 06:54:00, immediately preceding the manual front door operation, indicating this was an authorized entry/exit attempt rather than a break-in.

Explanation: The water leak sensor activated at 17:56:00, exactly one minute after the entrance occupancy detected someone entering; however, the raw log shows the person entered via the front door and there is no subsequent motion data inside the bathroom to suggest they used it, implying the sensor may have reacted to residual moisture or a false positive without actual flooding.

Explanation: Temperature values (e.g., 2395) are consistently high across all rooms during the night and morning, indicating a unit scaling issue where temperatures are recorded as integers in Kelvin or a similar offset format, not absolute degrees Celsius, which explains the lack of 'fire_risk' despite high numbers.

[2026-06-26T06:54:00] bedroom_occupancy | OccupancySensing.Occupancy = 1 followed by [2026-06-26T06:54:09] front_door_lock

[2026-06-26T17:56:00] entrance_occupancy | OccupancySensing.Occupancy = 1 occurring just before the bathroom leak alert

Verify if the water leak sensor requires recalibration or cleaning due to potential false positives.

Review temperature sensor firmware to understand the scale offset (likely Kelvin vs Celsius) for accurate thermal monitoring.

Timestamp and MAC address/IP of the 'Manual' lock operation source to identify if it matches a known resident device.

Duration between the first manual unlock/lock cycle and the subsequent auto-lock event.

Motion sensor logs immediately preceding the water leak event to determine if someone was present in the bathroom.

Camera footage (if available) around 06:54 AM and 17:56 PM to visually confirm presence or intrusion.
