The event sequence is consistent with a routine morning alarm caused by cooking smoke and the homeowner manually securing the house before leaving.

Explanation: Smoke alarm activation at 05:05 correlates directly with a sudden temperature spike in the kitchen sensor (2444 to 3500) followed by stabilization, indicating overheating equipment or grease fire rather than an external break-in.

Explanation: Occupancy sensors remained '0' throughout the night until 06:24 when bedroom occupancy turned '1', lights turned on, and windows opened, confirming the resident woke up naturally and was present in the home.

Explanation: The manual lock operation at 07:20:19 is immediately followed by an 'Auto' unlock at 07:20:26 coinciding with the door contact opening; this pattern matches the resident exiting the house (unlocking after locking) rather than a forced entry scenario.

[2026-06-05T05:00:00] kitchen_temp_sensor | MeasuredValue = 3500

[2026-06-05T06:24:04] bedroom_light | OnOff.OnOff = True

[2026-06-05T07:20:21] front_door_contact | BooleanState.StateValue = False

Check the kitchen for signs of grease accumulation or electrical issues near the cooktop.

Verify the smart lock's auto-unlock logic is functioning as intended for exit scenarios.

Timestamps and duration of the front door lock/unlock cycle around 07:20 to determine if it was a successful unlock followed by re-lock or just a toggle.

Video feed from entrance/living room between 05:05 and 07:30 to verify human presence or signs of forced entry.

Kitchen smoke alarm type and cause (false positive due to grease/cooking vs. actual fire) and whether the kitchen motion sensor was triggered simultaneously.

Whether the 'Auto' source at 07:20:26 corresponds to a smart lock feature that engaged upon detecting no motion, or if it was a system glitch.

The occupancy sensors are reporting a false 'empty' state for the entire night and early morning, which contradicts the clear evidence of human activity (lights on, window opened, door unlocked) occurring within that same timeframe.

Explanation: Occupancy logs show all rooms as empty ('0') from 00:00 to 06:40, suggesting no one was home.

Explanation: However, raw logs at 06:41 show bedroom lights turning ON and a window being opened, followed by bathroom occupancy detecting presence at 06:53, proving people were present and active.

Explanation: The front door was manually unlocked at 07:29 by an occupant inside (who turned off bedroom lights moments prior), but the system falsely believed the house was unoccupied during this period.

Explanation: This indicates a sensor calibration failure or drift where motion/occupancy detection is not triggering despite physical presence, leading to potential security gaps if automated responses rely on these false negatives.

[2026-06-09T00:00:00] ... OccupancySensing.Occupancy = 0 (Repeated until 06:40)

[2026-06-09T06:41:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-09T06:41:09] bedroom_light | OnOff.OnOff = True

Immediately reset or recalibrate the living room, bedroom, and bathroom occupancy sensors.

Review historical logs to determine the duration of the sensor malfunction before 06:41.

Verify the type of occupancy sensor used (PIR vs. multi-sensor) and check for environmental factors (e.g., direct sunlight, pet interference) that may have caused the initial failure.

Whether the 'Occupancy = 0' state at 00:00 and subsequent hours represents a system reset, sensor failure, or genuine lack of presence.

The event sequence represents normal morning routine activities with no evidence of unauthorized entry or system malfunction.

Explanation: All occupancy sensors (living room, bedroom, bathroom) were empty from 00:00 to 06:29, indicating the house was vacant during the night and early morning.

Explanation: Occupancy was detected in the bedroom at 06:30, followed immediately by light activation and window opening, confirming a resident woke up naturally.

Explanation: The door lock events at 07:22 show a manual unlock followed by an auto-lock within 11 seconds; given the prior occupancy detection and subsequent lack of forced entry attempts or alarm triggers, this is consistent with a resident leaving the home.

Explanation: Temperature readings are realistic (rising from ~22°C overnight to ~25°C in the morning), refuting sensor drift or hardware failure theories.

[2026-06-19T06:30:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-19T07:22:04] bedroom_light | OnOff.OnOff = False

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

Continue monitoring standard daily logs.

Standard percentage values are typically 0-100. A value of 10000 suggests a data parsing error, calibration issue, or firmware glitch rather than a physical impossibility (fully open).

Sequence of Manual Unlock -> Auto Lock within 11 seconds on June 19 at 07:22 without clear occupancy context prior to the unlock.

Door lock state transition from 2 (Unlocked) to 1 (Locked) occurring after a manual unlock operation, implying the door was left ajar or opened manually before being secured automatically.

Check camera footage or motion sensor logs specifically around 07:22:00 - 07:22:30 to confirm if anyone physically approached or entered the entrance.

Verify the definition of LockOperationType codes (1 vs 0) and LockState codes (1 vs 2) in the device firmware documentation to ensure correct interpretation.

Review the raw signal strength and timestamp precision for the door lock events to rule out clock skew or duplicate event logging issues.

火灾风险警报，建议住户检查该区域电器

A sustained, high-temperature fire hazard exists in the kitchen while the house is unoccupied and a smoke alarm has been triggered.

Explanation: Temperature sensors show a continuous and significant rise in kitchen temperature from 22.66°C at 00:00 to 24.99°C by 06:43, indicating an active heat source rather than ambient fluctuations.

Explanation: Occupancy logs confirm the home was empty (all rooms reporting 0) during these critical hours, meaning no occupants were present to extinguish the potential fire or respond to early warnings.

Explanation: The smoke alarm officially triggered at 21:36, but the prolonged temperature spike starting several hours prior suggests the fire risk was present long before the final alarm state.

[2026-06-22T00:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2266

[2026-06-22T06:43:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2499

Immediately dispatch emergency services to the location for fire inspection.

Instruct occupants not to enter the kitchen until professionals have verified it is safe.

Check kitchen appliances for ignition sources or malfunctioning heating elements.

No temperature spikes reported in evidence packet to confirm heat source

Front door manually unlocked then automatically re-locked within 5 minutes at 07:33

Kitchen smoke alarm activation at 18:03 persisting through late evening

Consistent zero occupancy readings across all rooms during early morning hours while doors/windows are being manipulated

Camera footage or motion sensor logs around 07:33 to verify if anyone entered/exited the house

Duration and intensity of the smoke alarm signal starting from 18:03 to distinguish between short-term cooking fumes vs sustained fire

Door lock actuator logs to determine if the 'Auto' unlock at 07:33 was a system glitch or triggered by an external force (e.g., smart home automation responding to a breach)

Window cover motor logs between 06:43 and 21:51 to check for forced opening attempts

The events represent a normal daily routine of residents leaving and returning to the home, supported by consistent occupancy data and lack of forced entry indicators.

Explanation: Occupancy sensors show full house vacancy at 00:00-06:39, confirming no one was inside during the night, which rules out unauthorized entry occurring while occupants were present.

Explanation: At 07:18, the sequence shows a manual lock followed immediately by an automatic unlock (or vice versa depending on state interpretation) alongside door contact changes consistent with opening/closing a door from the inside/outside in a controlled manner, not a forced breach.

Explanation: Crucially, the raw log shows bedroom occupancy turning ON at 06:40 and OFF at 06:50, proving a resident was awake and active in the house before leaving at 07:18, making the 'manual lock' a standard action by a resident rather than an intruder.

[2026-06-01T06:40:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

No immediate action required; continue monitoring.

Verify that the 'Auto' unlock source at 07:18 corresponds to a scheduled exit protocol or is a system quirk if unexpected, but given human presence prior, it is likely benign.

Timestamps of motion sensor triggers in living_room and entrance immediately preceding/following the 07:18 door events to confirm occupant movement direction.

User authentication logs for the manual lock operation to verify if it matches a known resident's device or physical key usage.

Historical patterns of door lock operations at 07:18 to determine if this is a recurring habit or an isolated incident.

Detailed state of window_covering motors during the 07:18 timeframe to ensure no forced entry via windows coincided with door manipulation.

Evidence indicates a potential break-in attempt characterized by an automated door unlock immediately following a manual lock while the house was unoccupied, coinciding with suspicious window state changes.

Explanation: The front door was manually locked at 07:21:17 but automatically unlocked just 6 seconds later (07:21:23) via 'Auto' source, which contradicts standard user behavior and suggests external manipulation or a compromised smart home system.

Explanation: Occupancy logs confirm no humans were present in any room between 07:21:00 and 07:22:00, ruling out internal residents as the trigger for the immediate re-unlocking.

Explanation: A subsequent anomalous sensor reading (window value 10000) occurred late in the evening when the house was again unoccupied, reinforcing a pattern of unauthorized interaction with environmental controls.

Front door lock sequence: Manual Lock (07:21:17) -> Auto Unlock (07:21:23) with zero occupancy detected.

Bedroom occupancy log shows 0 occupants during the incident timeframe (07:21 - 07:22), making resident-triggered automation impossible.

Immediately change all smart home account passwords and enable multi-factor authentication.

Review network logs to identify if the 'Auto' unlock command originated from an unknown IP address or device ID.

Physically inspect the front door locks and bedroom windows for signs of tampering or forced entry.

The extremely short duration between manual lock (07:21:17) and auto unlock (07:21:23) is highly unusual for standard scheduling logic.

The lack of any human presence (occupancy sensors off) while the door is being manipulated suggests an external actor or a hijacked account rather than an internal resident acting normally.

The window covering value '10000' is technically invalid (max usually 10000ths/100%), indicating a potential sensor malfunction or forced override which is not typical normal behavior.

Door unlocked via 'Auto' source within 6 seconds of a 'Manual' lock event without any intermediate user interaction log.

Bedroom window coverings changed from closed (0) to an anomalous high value (10000) shortly after the door unlocking sequence.

Zero occupancy detected across all rooms during the timeframe of the door/window anomalies.

Check network logs for API calls originating from IP addresses other than known trusted devices (phones/tablets) around 07:21:17 - 07:21:23.

Verify if the 'Auto' source corresponds to a specific smart device ID (e.g., a scheduled scene) or if it maps to an unknown/generic controller.

Inspect the raw state transition of the bedroom window covering motor to determine if it physically moved or if the sensor reading is corrupted.

Cross-reference mobile app usage logs to see if the homeowner's phone received notifications or triggered these actions remotely.

A confirmed fire risk event occurred due to a kitchen smoke alarm triggering while an electric cooktop was active and temperatures were critically elevated.

Explanation: Kitchen temperature rose steadily from 22°C at midnight to over 240°C by 04:15, indicating uncontrolled heating.

Explanation: The cook surface (cook_surface) turned ON at 04:04, coinciding with the sharp temperature spike before the alarm triggered.

Explanation: At 04:19:00, the kitchen smoke alarm explicitly reported SmokeState=1 and Event: SmokeAlarm(), confirming a real hazard rather than a sensor error.

The sequence of events indicates a resident performing a routine late-night security check to ensure the house was secure before sleeping, rather than an intrusion attempt.

Explanation: Occupancy logs show the resident was present in the master bedroom at 22:39:12, confirming the house was not vacant when the door unlocked.

Explanation: The 'Auto' unlock event at 22:39:25 coincides exactly with the resident manually closing the window (likely via voice command or app), suggesting an automated system triggered by the user's presence/action rather than an external breach.

Explanation: Crucially, the front door contact sensor immediately returned to 'Closed' (True) at 22:39:24, proving the door remained shut and no physical entry occurred during the lock cycle.

[2026-06-11T22:39:12] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-11T22:39:24] front_door_contact | BooleanState.StateValue = True

Continue standard monitoring; no immediate intervention required.

Optionally verify if the 'Auto' unlock source code corresponds to a known user-initiated automation rule for night-time checks.

[2026-06-11T07:33:25] front_door_lock | DoorLock.LockState = 1

High count of entrance events (26) relative to low kitchen/living room activity suggests focused attention on the door rather than domestic chores.

Window fully closed (100%) at 22:39:15 immediately preceding the door unlock event, potentially indicating a sequence of securing then breaching, or a false positive trigger causing the lock cycle.

Check the specific reason code for the 'Auto' source lock unlock event at 22:39:25 (e.g., motion detection, tamper alert, panic button).

Verify the state of the front door contact sensor immediately following the 22:39:25 unlock event to see if the door opened or stayed closed.

Review the full list of 1837 events filtered by 'entrance' between 20:00 and 23:00 to identify any sensor triggers (motion, vibration) correlating with the high event count.

Confirm the status of the master bedroom motion sensor around 22:39 to rule out a false wake-up causing the user to re-check the door.

No security threat detected; observed events are consistent with routine daily activities (leaving/returning home) and a non-fire smoke alarm trigger.

Explanation: The late-night front door event at 21:59:30 shows the door contact opening followed immediately by an automatic lock state change, but no subsequent motion sensor triggers in living areas or occupancy changes indicating entry occurred.

Explanation: The kitchen smoke alarm activation at 18:48 coincided with high occupancy counts ('kitchen': 14) and was likely a false positive caused by cooking steam, as no fire-related temperature spikes or persistent smoke states were logged afterwards.

Explanation: All other timestamps align perfectly with normal household patterns: morning departure (07:16), evening return (18:21), and overnight vacancy confirmed by zero occupancy readings throughout the night.

[2026-06-19T21:59:29] front_door_contact | BooleanState.StateValue = True

Camera feed logs (if available) for the front door area around 21:59:30.

Kitchen smoke alarm diagnostic logs to distinguish between false positive (e.g., cooking steam) and actual fire.

触发安全警报，临时禁用 Keypad 输入，通知住户

Multiple repeated lock failure attempts and a subsequent alarm at the front door indicate a forced entry or tampering event.

Explanation: The log shows four consecutive 'LockOperationError' events with 'OperationSource=3' within a 25-second window starting at 14:17:00, suggesting repeated physical interaction or automated jamming.

Explanation: A 'DoorLockAlarm' was triggered immediately after the error sequence (14:17:50), confirming the system detected an intrusion attempt rather than a simple mechanical glitch.

Explanation: While the door was successfully unlocked manually at 16:01, this likely represents the resident returning to secure their home after realizing the breach or clearing a false alarm caused by the intruder's failed attempts.

[2026-06-29T14:17:00] ... LockOperationError(OperationError=1, OperationSource=3)

Check security camera footage for the entrance between 14:17 and 14:20 to identify the perpetrator.

Inspect the physical condition of the front door and handle for signs of forced entry (e.g., bent lock cylinder, scratched paint).

Contact local authorities to file a report given the confirmed alarm trigger and repeated access attempts.

Possible window manipulation in the master bedroom around 22:35, coinciding with a change in lock state.

[2026-06-29T22:35:20] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual)

[2026-06-29T22:35:17] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

[2026-06-29T22:35:20] front_door_lock | DoorLock.LockState = 1

Window covering value '10000' may indicate a sensor fault or specific protocol encoding for 'fully closed' rather than open; requires verification.

Repetitive LockOperationErrors (Source 3) on the front door within a 50-second window starting at 14:17:00.

DoorLockAlarm triggered immediately after the error sequence.

Subsequent successful manual lock/unlock operations occurring shortly after the alarm.

Timestamps of motion sensor activations near the entrance hallway during the 14:17 incident to see if someone was physically present attempting entry.

The specific definition of 'OperationSource=3' in the device firmware documentation (likely indicates tamper, keypad failure, or physical force).

History of the master bedroom window cover actuator to confirm if the position change at 22:35 was intentional or a glitch.

Audio logs or camera footage from the entrance doorbell/camera if available to visualize the 14:17 interaction.

The events represent a normal evening routine where residents secured the house manually before sleeping and engaged in standard pre-dawn maintenance (closing windows) followed by automated security protocols.

Explanation: Occupancy logs confirm full vacancy of all rooms between 00:00 and 07:15, ruling out an undetected intruder during the night.

Explanation: The sequence at 22:10 shows master bedroom occupancy first, then window closure, which is consistent with a resident returning to bed and closing curtains/blinds rather than leaving the house.

Explanation: The auto-unlock event at 22:10:25 immediately preceded by a door contact 'open' signal (state True) indicates the system correctly detected an open door or sensor trigger (likely from the window mechanism affecting proximity sensors or a scheduled check) and unlocked it for ventilation/access, rather than an intrusion attempt.

Explanation: Morning logs show manual locking at 07:15 and 16:25, confirming the system relies on user intervention for final security, making the mid-night auto-event a functional automation rather than a breach.

[2026-06-09T00:00:00] ... OccupancySensing.Occupancy = 0 (All rooms empty overnight)

[2026-06-09T22:10:19] master_bedroom_occupancy | OccupancySensing.Occupancy = 1 (Presence confirmed before window action)

[2026-06-09T22:10:24] front_door_contact | BooleanState.StateValue = True (Door state change triggered lock logic)

Review smart-home automation rules to ensure the 'auto-unlock' triggered by window closure or door contact does not conflict with 'Away Mode' schedules if users prefer doors remain locked while sleeping.

Verify that the living room window contact sensor state at 02:40 aligns with actual window status to rule out sensor drift causing intermittent triggers.

[2026-06-09T07:15:31] front_door_lock | DoorLock.LockState = 2

[2026-06-09T07:15:38] front_door_lock | DoorLock.LockState = 1

[2026-06-09T16:25:00] front_door_lock | DoorLock.LockState = 2

High total occupancy counts (1839 events) and spread across all rooms during daytime hours strongly support legitimate resident presence.

No smoke, leak, or temperature anomalies reported.

Vacancy reports at 00:00 and 00:30 confirm the house is empty later, consistent with residents sleeping or being away.

[2026-06-09T22:10:21] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

[2026-06-09T22:10:25] front_door_lock | DoorLock.LockState = 1

Check raw logs for motion sensor readings in the entrance hallway and living room between 18:16 and 22:10 to rule out silent entry.

Verify the source of the 'Auto' unlock command at 22:10:25 (was it triggered by the window sensor closing, a schedule, or external tampering?).

Confirm if the window closure event at 22:10:21 was a manual user action or automated by a smart-home routine upon detecting the last occupant.

The event at 21:47 represents a normal automated evening return and locking sequence for an authorized user, consistent with the pattern established at 18:24.

Explanation: The occupancy sensors confirm the house was empty (Occupancy=0) from 00:00 through 21:45, establishing a period of vacancy.

Explanation: The event at 21:47:33 shows 'LockOperationType=0' (Unlock) followed immediately by 'LockState=1' (Locked), indicating the door was unlocked and then re-secured.

Explanation: This sequence mirrors the earlier event at 18:24 where UserIndex=1 performed a similar manual/automated unlock-and-lock routine, confirming this is a standard evening arrival protocol rather than unauthorized entry.

Explanation: The temperature data shows no signs of heating anomalies or intrusion activity that would contradict a normal exit/entry cycle.

中等可信度警报，建议住户确认是否本人操作

The event is a normal resident departure and subsequent return, confirmed by occupancy logs showing the house was empty only between 00:00 and 07:39.

Explanation: Occupancy sensors across all rooms consistently report 0 (empty) from 00:00 to 07:39, but show occupancy=1 at 07:39:15, proving the house was vacant when the 18:11 lock operation occurred.

Explanation: The front door contact sensor shows the door opening at 18:11:02 immediately after the manual lock command, followed by closing at 21:50:34, indicating a standard exit/entry cycle rather than forced entry or tailgating.

Explanation: The sequence at 07:39 (occupancy detected -> manual unlock -> auto-lock) establishes the baseline for normal daily routines, confirming the system logic works correctly and the 18:11 event fits this pattern.

The front door was unlocked and subsequently re-locked automatically at 23:04 while the entire house has been completely empty since midnight, strongly indicating an unauthorized entry attempt.

Explanation: All occupancy sensors reported '0' (empty) continuously from 00:00 through 23:04, confirming no residents were present to trigger a legitimate auto-lock or exit.

Explanation: The log shows a specific contact event ('front_door_contact | BooleanState.StateValue = True') immediately preceding the 'Auto' lock operation, proving physical interaction with the door occurred in the absence of occupants.

Explanation: The temperature data confirms the home environment is static and unoccupied during this window, ruling out a resident leaving recently.

The event sequence represents a standard evening departure routine involving manual locking followed by automated window closure and final auto-locking, with no signs of forced entry or intrusion.

Explanation: Occupancy sensors confirm the house was empty from midnight until the resident's return at 16:01, consistent with normal sleeping hours.

Explanation: Manual lock operations at 07:16, 16:02, and 18:20 coincide with occupancy events (return home) or known daily routines, indicating human agency rather than unauthorized access.

Explanation: The critical sequence at 22:20 shows the master bedroom curtain being closed immediately before the front door automatically locked; this temporal correlation strongly suggests a user-initiated 'goodnight' or departure automation triggered by closing the window covering.

Explanation: Contact sensor logs show clean transitions (Open -> Closed -> Locked) without evidence of prolonged open states or forceful manipulation typical of break-ins.

[2026-06-10T18:20:00] Manual Lock Operation followed shortly by [2026-06-10T22:20:12] Curtain Closing and [2026-06-10T22:20:19] Auto-Lock.

Motion sensor raw data stream specifically between 07:18:00 and 07:20:00 to see if any micro-movements were missed or if the sensor was blinded.

Door lock operation logs to verify the specific user ID associated with the Manual unlock at 07:18:17.

Water flow meter logs in the bathroom leading up to 15:45:00 to determine the duration and source of the leak.

Camera footage (if available) covering the entrance hallway and living room around 07:18 AM.
