FG-02-FP: 电暖器/取暖器正常使用

有人在房间且温度上升后趋于稳定（不是持续飙升），无烟雾报警触发

No security threats detected; all door lock operations align with occupancy data and exhibit normal automated behavior.

Explanation: Occupancy sensors confirm the house was empty at midnight (H2 supported).

Explanation: Manual lock events at 07:22:20 and 18:00:00 immediately preceded by entrance occupancy spikes indicate authorized family members arriving and leaving.

Explanation: All 'Auto' lock operations occurred immediately after the door contact sensor closed/opened, consistent with standard smart-home automation rather than tampering.

[2026-06-01T07:22:12] entrance_occupancy | OccupancySensing.Occupancy = 1

[2026-06-01T17:57:23] entrance_occupancy | OccupancySensing.Occupancy = 1

Continue monitoring standard daily logs.

[2026-06-01T18:00:00] front_door_lock | DoorLock.LockState = 2

[2026-06-01T22:13:47] front_door_lock | DoorLock.LockState = 1

Check user identity/authentication logs for the Manual LockOperation events at 07:22:20 and 18:00:00 to confirm if they were authorized family members.

Verify the state change between 'LockState = 2' and 'LockState = 1' timestamps to ensure no prolonged window of unlocked access.

Cross-reference motion sensor data in the living room and hallway immediately surrounding the 07:22 and 22:13 timestamps.

FG-03-FP: 烟雾报警器自检触发CO检测

The system is in a secure state; the reported CO alarm was a successful self-test confirmed by immediate reset and completion events.

Explanation: All occupancy sensors report '0' during the monitored night window (00:00-04:30), confirming no intrusion or presence.

Explanation: Temperature readings show a gradual rise from ~2270 to ~2411, which represents normal ambient drift or HVAC cycling and does not indicate fire risk.

Explanation: The only concerning signal (COState=1) at 15:37:05 was immediately followed by TestInProgress=False and SelfTestComplete within 25 seconds, explicitly ruling out a genuine carbon monoxide leak.

[2026-06-19T15:37:00] ... SmokeCoAlarm.TestInProgress = True

Occupancy sensors consistently report Occupancy = 0 throughout the night.

No intervention required as the event was verified as a scheduled test.

[2026-06-19T18:21:00] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual)

Verify the exact device ID associated with the 'SmokeCoAlarm' data point to confirm if it originated from the kitchen smoke detector or the bedroom lighting controller logic.

Check the raw timestamp resolution between 'COState=1' and 'SelfTestComplete' to ensure there was no lingering true alarm before the test cleared it.

Review the 'front_door_lock' event stream around 21:58 to confirm the user physically unlocked the door manually versus an automated unlock sequence, given the high activity count in entrance (24).

BA-04-FP: 传感器触发延迟导致顺序看似跳跃

客厅occupancy在阳台和主卧之间有触发（2秒时），移动路径合理

The simultaneous zero occupancy across all zones from 00:00 onwards, combined with the absence of any door/window breach events and normal temperature rise trends, confirms a standard overnight vacancy scenario.

Explanation: Occupancy sensors in all critical areas (entrance, living room, bedrooms) reported 0 simultaneously starting exactly at 00:00:00, consistent with a household leaving together or sleeping patterns ending.

Explanation: No contact sensor breaches were recorded for the entrance door or windows between the last activity and the start of the vacancy period, ruling out unauthorized entry.

Explanation: Ambient temperature sensors show a steady, natural increase over time (22.6°C to 24.6°C), indicating no HVAC malfunction, fire, or intrusion altering the thermal profile.

Timestamp 2026-06-06T00:00:00 shows Occupancy = 0 for all monitored rooms simultaneously.

No log entries indicate 'door_open' or 'window_open' states during the evidence window.

Continue routine monitoring; no immediate intervention required.

Verify that all residents safely exited the premises before 00:00 if this was an expected departure time.

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

Simultaneous zero occupancy across ALL monitored zones (entrance, living_room, bedrooms, bathroom) starting at 00:00:00 and persisting through 01:30:00.

Discrepancy between 'room_activity' counts indicating significant usage (total ~84 events) and the sudden, absolute cessation of motion detection across every zone immediately after midnight.

Check the state history of 'entrance_contact_sensor' and all 'window_contact_sensor' devices between 23:00 and 00:30 to confirm the main door and all windows were closed/latched.

Verify the timestamp and sequence of the last 'door_open' or 'window_open' event relative to the first 'occupancy=0' event at 00:00:00.

Review 'living_room_occupancy' logs immediately preceding 00:00:00 to determine the exact moment the last resident exited the premises.

Cross-reference 'onoff_light' logs to see if lights were turned off systematically or remained on in specific rooms, which could indicate delayed departure or partial occupancy.

客厅occupancy在阳台和主卧之间有触发（2秒时），移动路径合理

The system data indicates a standard night-time occupancy pattern with no signs of unauthorized entry or sensor malfunction; the high event count is explained by scheduled polling intervals and normal door lock cycles.

Explanation: Occupancy sensors consistently report '0' (empty) for all rooms between 00:00 and 05:00, confirming the house was unoccupied during the night.

Explanation: The repetitive timestamps (e.g., every 30 minutes) correspond to automated system polling cycles rather than random human activity or intrusion attempts.

Explanation: Door contact sensors show a clear, logical sequence: state changed to False (open) immediately after manual lock operation and returned to True (closed), ruling out tailgating or forced entry.

Explanation: No 'Tamper', 'Low Battery', or 'Communication Lost' flags were detected in the logs to suggest sensor failure.

Multiple occupancy sensors reporting '0' across all rooms from 00:00 to 07:13.

Front door contact sensor showing BooleanState=False followed quickly by True after LockOperation events at 07:13 and 21:49.

Continue monitoring routine operations.
No immediate intervention required.

[2026-06-10T21:49:30] front_door_lock | DoorLock.LockState = 1

Discrepancy between high total event count (1657) and low salient event count (60), indicating potential sensor noise or unlogged physical interactions.

Concentration of 'entrance' activity (23 events) which could imply frequent checking of the door status without corresponding occupancy.

Timestamps immediately preceding the 07:13 and 18:16 front_door_lock events to check for approach vectors or failed unlock attempts.

Raw contact_sensor readings for the entrance door to verify if the door was physically opened/closed vs. just electronically toggled.

Check for any 'low_battery' or 'communication_lost' flags on the entrance motion/contact sensors that might cause false readings.

Verify the exact time range covered by the 1657 events to see if this represents a single hour or a full day's accumulation.

BA-05-FP: 邻居/亲友代为浇花/喂宠物

通过门锁合法进入（有效的临时 UserIndex），进出有完整的开锁+锁门记录

The sequence of events indicates a legitimate resident entering the home manually and the smart lock performing its standard automatic re-locking function; the apparent anomaly was resolved by cross-referencing contact sensor data confirming door closure.

Explanation: Analysis of the raw log at 07:21:15 shows 'entrance_occupancy' changing to 1, indicating a person entered before the manual lock event.

Explanation: At 07:21:24, the front_door_contact sensor reported False (door open), followed immediately by True at 07:21:28 (door closed), physically confirming the door was opened and then shut.

Explanation: The 'Manual' lock operation occurred while the door was being operated, and the subsequent 'Auto' lock at 07:21:29 corresponds to the door closing state change, which is consistent with standard smart-lock behavior rather than a security breach.

Explanation: Later events (08:04, 18:23) show authorized UserIndex=5 operations, establishing a pattern of legitimate activity.

[2026-06-26T07:21:15] entrance_occupancy | OccupancySensing.Occupancy = 1

[2026-06-26T07:21:24] front_door_contact | BooleanState.StateValue = False

[2026-06-26T07:21:28] front_door_contact | BooleanState.StateValue = True

Continue monitoring for any future discrepancies between manual lock commands and contact sensor readings.

Review system logs periodically to ensure no similar patterns recur without corresponding occupancy or contact changes.

[2026-06-26T00:00:00] master_bedroom_occupancy | OccupancySensing.Occupancy = 0

[2026-06-26T00:30:00] entrance_occupancy | OccupancySensing.Occupancy = 0

Room activity counts suggest significant movement earlier (Kitchen: 10, Living Room: 22, Entrance: 30), implying presence before 00:00.

Manual lock operation at 07:21:22 immediately followed by an automatic lock operation at 07:21:29. The 'Manual' source combined with a rapid transition to 'Auto' state change suggests a possible bypass attempt, sensor glitch triggered by tampering, or a smart-lock malfunction where it re-engaged automatically after being manually manipulated.

The sequence of LockState 2 (Unlocked/Open) -> LockState 1 (Locked) occurring within 7 seconds twice (morning and night). If the manual unlock was not initiated by an authorized user (no UserIndex attached like the others), this is suspicious.

Check the raw event log for 'front_door_contact_sensor' readings around 07:21:22. Did the door actually open?

Verify the device firmware version and known bug list for the specific door lock model regarding 'Auto' re-locking behavior after manual intervention.

Cross-reference the IP address or MAC address associated with the 'Manual' lock operation at 07:21:22 against the list of authorized users (UserIndex 5 and others).

Review motion sensor logs between 06:00 and 07:30 to see if anyone entered the living room or kitchen prior to the suspicious lock event.

BA-04-FP: 传感器触发延迟导致顺序看似跳跃

客厅occupancy在阳台和主卧之间有触发（2秒时），移动路径合理

A critical smart lock logic failure occurred where a manual lock command was immediately overridden by an automatic unlock event, leaving the front door unsecured during a time when the household was reported as empty.

Explanation: The raw log shows a sequence at 07:36 where a Manual Lock operation (LockState=2) was executed, but exactly 10 seconds later, an Auto Unlock operation (LockState=1) occurred without any corresponding Manual Unlock trigger or occupancy presence.

Explanation: This contradicts standard security protocols and routine behavior (compared to the 16:07 and 17:45 events which were consistent manual locks), indicating a firmware bug or a system glitch rather than user intent.

Explanation: Although no motion sensors detected entry at that specific moment, the door was left unlocked while the house was empty, creating a significant vulnerability that could be exploited if someone approached shortly after.

[2026-06-23T07:36:25] ... Event: LockOperation(LockOperationType=1, OperationSource=Manual)

[2026-06-23T07:36:35] ... Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Immediately check the physical status of the front door lock mechanism to ensure it is mechanically secure.

Review the smart lock's firmware version and logs for known bugs regarding 'Auto' overrides following manual commands.

Temporarily disable automated unlock schedules and require manual verification for all future lock operations until the issue is resolved.

[2026-06-23T16:07:00] front_door_lock | DoorLock.LockState = 2

Master bedroom window blind fully raised (100%) shortly before the suspicious front door activity (which occurred earlier that day) or potentially indicating preparation for entry/exiting if timestamps were misaligned, though the timestamp 22:24 suggests late night. Note: The suspicious door event was at 07:36, while blinds moved at 22:24. This might indicate someone was present in the master bedroom late at night while the house was supposed to be locked down, or an automated schedule conflict.

[2026-06-23T22:24:29] front_door_lock | DoorLock.LockState = 1 (Unlocked state often persists after auto-unlock events or indicates failure to re-lock)

[2026-06-23T22:24:18] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Rapid transition of front door lock from Manual Lock -> Auto Unlock within 10 seconds at 07:36 AM.

Front door LockState changing to 1 (Unlocked) at 22:24, coinciding with Master Bedroom blinds being fully open, despite no occupancy reports at that exact minute.

High frequency of focus events (91) vs salient events (60) suggests many minor anomalies or noise, but the door logic error stands out.

Check the raw motion sensor data around 07:35-07:40 AM to see if anyone entered the foyer area before the lock glitch.

Verify the source code or firmware version of the smart lock to determine if 'Auto' unlock after manual lock is a known bug or security feature (e.g., panic button release).

Cross-reference the master bedroom occupancy sensor logs between 22:24 and 07:36 to confirm if anyone was inside the bedroom during the night.

Check if the 'Auto' unlock at 07:36 was triggered by a geofence exit event or a scheduled automation, or if it was an unexplained system reset.

通过门锁合法进入（有效的临时 UserIndex），进出有完整的开锁+锁门记录

An unauthorized individual (UserIndex=5) successfully unlocked and entered the home in the late evening, as confirmed by sensor data showing door contact changes and subsequent room occupancy.

Explanation: Raw logs show a sequence at 22:47 where UserIndex=5 performed a lock operation (Type=1), followed immediately by a front_door_contact state change to False (door opened).

Explanation: Occupancy sensors confirm a person was present in the entrance at 22:45 and again at 22:55, correlating with the door interaction.

Explanation: Crucially, living_room_occupancy changed to 1 at 22:57:04, proving the intruder gained entry beyond just touching the door handle.

Explanation: UserIndex=5 is not among the known residents (who use Manual or Auto sources) and appears only during this specific suspicious event.

[2026-06-24T22:57:04] living_room_occupancy | OccupancySensing.Occupancy = 1

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

Notify all household members of the incident and secure the premises if they are currently inside.

Review video footage from the entrance/balcony between 22:45 and 23:00 to identify the suspect.

Audit device registration logs to determine who registered UserIndex=5 and revoke access if unauthorized.

FG-04-FP: 低电量报警但传感器仍正常工作

虽然电池低但传感器仍然能正常检测烟雾（SmokeState变1又恢复0），说明设备没失灵

A kitchen fire event occurred while the house was unoccupied and the smoke alarm battery was low, resulting in a delayed detection (approx. 30 mins) before residents returned.

Explanation: The raw log shows 'SmokeCoAlarm.SmokeState = 1' at 22:39:00, indicating active smoke/fire detection.

Explanation: Occupancy logs confirm all rooms were empty ('Occupancy = 0') from midnight until 22:35 when occupancy resumed, meaning the fire burned unchecked for nearly 22 hours.

Explanation: The initial 'BatteryAlert = 1' at 22:29 suggests a compromised sensor, which likely contributed to the delayed or ineffective response prior to the smoke state triggering.

Explanation: The fire extinguished itself ('SmokeState = 0') shortly after detection, but the long duration of undetected heat/smoke poses a significant safety risk.

[2026-06-17T22:29:00] kitchen_smoke_alarm | SmokeCoAlarm.BatteryAlert = 1

Immediately replace the kitchen smoke alarm battery and test the unit.

Inspect the kitchen area for soot, damage, or lingering odors that might indicate an ongoing hazard.

Consider installing a backup power source or hardwired smoke detector in the kitchen.

[2026-06-17T18:19:00] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual)

master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 (fully open) while occupancy is 0

Check for specific timestamps of window motor activity vs. lock state changes to determine if someone entered through the bedroom window.

Verify if the front door manual locks were performed by a known user device or if they occurred without authentication logs.

Cross-reference kitchen temperature and gas sensor data around the time of the battery alert to rule out minor heating issues causing low battery drain.

BA-04-FP: 传感器触发延迟导致顺序看似跳跃

客厅occupancy在阳台和主卧之间有触发（2秒时），移动路径合理

The sequence of events represents a legitimate 'Geofence Exit' automation where the resident manually locked the door while outside (or in transit), triggering an immediate auto-unlock for their return, which was subsequently confirmed by the contact sensor.

Explanation: Occupancy logs show zero presence until 07:38:08, establishing the house as empty and secured prior to the event.

Explanation: At 07:38:16, a manual lock occurred, followed immediately by a contact sensor reading 'False' (door open) at 07:38:18, proving physical movement occurred.

Explanation: The 'Auto' unlock at 07:38:24 is corroborated by the contact sensor returning to 'True' (closed) just one second later, indicating a standard departure/return cycle rather than a forced entry or malfunction.

Explanation: This pattern mirrors the clean routine observed at 21:58, confirming it as established normal behavior for this household's smart-lock automation.

[2026-06-15T07:38:18] front_door_contact | BooleanState.StateValue = False

[2026-06-15T07:38:23] front_door_contact | BooleanState.StateValue = True

Continue monitoring standard occupancy and temperature baselines.

No immediate intervention required; verify no other anomalies appear in subsequent logs.

[2026-06-15T18:21:00] front_door_lock | DoorLock.LockState = 2

[2026-06-15T21:58:35] front_door_lock | DoorLock.LockState = 1

The specific sequence of manual lock followed by immediate auto-unlock at 07:38 might indicate an intrusion rather than just a departure.

Front door lock transition from Manual Lock to Auto Unlock within 8 seconds without a corresponding Manual Unlock event or extended duration of lock state 1 before re-locking.

Discrepancy between the 07:38 incident (suspicious timing relative to typical wake-up/morning commute) and the 21:58 incident (likely end-of-day routine).

Check if the 07:38:24 'Auto' unlock triggered a subsequent 'Manual Open' event or if the door remained open longer than expected.

Verify the source IP or device ID associated with the 'Auto' unlock command at 07:38:24 to distinguish between a smart-device trigger (e.g., geofence exit) and a potential spoofed signal.

Review the contact sensor log for the front door around 07:38:24 to confirm if the door actually opened physically at that moment.

FG-03-FP: 烟雾报警器自检触发CO检测

High-probability unauthorized entry or forced lock manipulation detected at the front door between 07:19:13 and 07:19:18, evidenced by an occupancy spike followed immediately by a state reversal that contradicts normal auto-locking logic.

Explanation: Occupancy sensor in the entrance triggered (Occupancy=1) at 07:19:09, indicating presence before the manual lock command.

Explanation: The contact sensor showed 'False' (Open) at 07:19:13, but then switched to 'True' (Closed) at 07:19:18 without a corresponding 'Unlock' event first; this sequence suggests the door was physically manipulated or propped open after being locked, or the lock mechanism failed to engage securely upon closing.

Explanation: While an Auto-Unlock occurred at 07:19:19, the intermediate contact state change combined with the specific timing of the manual lock followed by immediate re-opening behavior is inconsistent with standard user entry/exit patterns and matches a breach attempt profile.

Immediately verify physical security status of the front door and check for signs of tampering.

Temporarily disable automatic re-locking features until the anomaly pattern is fully understood.

Verify if any motion sensors in the hallway/entrance triggered before or after the 07:19 manual lock event.

Review the state history of the contact_sensor on the front_door to see if the door was physically opened/closed multiple times between 07:19:11 and 07:19:19.

No security breach detected; the sequence of events indicates a user opening the door from inside to unlock it (triggering auto-lock) or a sensor delay, followed by normal manual locking upon return.

Explanation: The temperature readings in Kelvin (e.g., 2276 K ~1943°C) are clearly sensor drift/malfunction data artifacts and do not indicate a real fire hazard given the lack of other thermal alarms or context.

Explanation: The critical event at 07:25 shows occupancy appearing (1) before the Manual Lock command, which contradicts an 'intruder' scenario where the door would be locked before entry is detected. This suggests the occupant was already inside, opened the door (contact=False), and the system triggered Auto Unlock (LockState=1) shortly after.

Explanation: The timeline confirms no forced entry: Occupancy became 1 at 07:25:06, Door Contact went False at 07:25:11, then True at 07:25:17, and Auto Unlock occurred at 07:25:18. The subsequent Manual Lock at 18:21 follows a standard evening routine pattern.

Explanation: The overnight period (00:00-07:00) shows zero occupancy consistently with sleep cycles, and the door remained secure (no unauthorized lock/unlock cycles).

[2026-06-22T07:25:11] front_door_contact | BooleanState.StateValue = False

Investigate the kitchen_temp_sensor and living_room_temp_sensor calibration to address the unrealistic Kelvin readings.

Verify if the entrance occupancy sensor has a delayed trigger response that caused the timestamp mismatch between occupancy detection and door contact.

No security anomalies detected; all observed events are consistent with routine household activities and scheduled maintenance.

Explanation: Smoke alarm COState=1 occurred only during the explicitly logged 'TestInProgress' phase and resolved immediately after self-test completion, confirming it as a scheduled artifact rather than a fire event.

Explanation: Front door lock state changes at 22:26 (Unlock -> Lock) align perfectly with occupancy sensors detecting a resident returning to the master bedroom at 22:26:19, indicating an authorized entry and subsequent locking sequence.

Explanation: The window covering closing at 22:26 coincides exactly with the resident's arrival in the bedroom, suggesting manual or app-initiated closure upon return rather than an automated malfunction while the house was empty.

[2026-06-18T22:26:19] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

Continue monitoring for any deviations from established patterns.

Verify that smoke detector batteries and sensors function correctly following the successful test.

FG-04-FP: 低电量报警但传感器仍正常工作

The front door lock exhibits a critical malfunction where an auto-lock command was issued without the door being fully closed (contact sensor still open), leaving the residence unprotected.

Explanation: At 07:33:21, a manual unlock occurred and the door contact sensor registered as False (open).

Explanation: At 07:33:31, the door contact sensor registered as True (closed), but the system immediately issued an 'Auto' lock command at 07:33:32.

Explanation: This sequence implies the system attempted to lock while the door might still be in transit or falsely detected as closed, yet the subsequent state change suggests a failure to verify the physical closure before engaging the latch, or a rapid cycle that compromised security integrity.

Explanation: Crucially, the gap between the Manual Unlock (07:33:21) and Auto Lock (07:33:32) is only 11 seconds, which is abnormally short for a resident to enter, retrieve keys/bag, close the door, and trigger an auto-lock, suggesting either an intrusion attempt via tailgating that failed due to speed, or more likely, a system logic error where the auto-lock triggered prematurely on a false positive from the contact sensor.

[2026-06-08T07:33:31] front_door_contact | BooleanState.StateValue = True

Inspect the front door strike plate and frame alignment immediately.

Clean and recalibrate the magnetic door contact sensor to ensure it accurately reflects the door's open/closed state.

Review the smart lock firmware settings to prevent auto-locking if the door is not confirmed physically latched for a minimum duration.

[2026-06-08T21:45:41] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Timestamps and duration between Manual Unlock and Auto Lock commands on the front door lock to determine if there was a dwell time exceeding normal thresholds.

DoorLock.LockState transition logs around 07:33 to confirm if the door remained unlocked during the manual operation window.

Contextual data (e.g., motion sensor triggers) in the hallway/kitchen immediately following the 07:33 door event.

Battery voltage readings for the kitchen smoke alarm prior to the battery alert.

温度上升后稳定（不持续飙升），住户定期回来检查，烟雾传感器未触发

Evidence indicates a potential intrusion where the master bedroom window was fully opened at night while occupants were present, triggering an automatic front door unlock sequence immediately after.

Explanation: At 22:21:19, the master bedroom window covering moved to 100% (fully open) while occupancy sensors confirmed a person was present in that room.

Explanation: Three seconds later at 22:21:22, the front door lock state changed to 'Unlocked' (State=1) via an 'Auto' source event, coinciding with the front door contact sensor briefly registering 'True' (open), suggesting forced entry or a triggered safety bypass.

Explanation: The timing of the window opening followed immediately by the door unlocking is inconsistent with standard routine activities and matches the pattern of H2 (potential unauthorized re-entry or protocol bypass).

[2026-06-23T22:21:21] front_door_contact | BooleanState.StateValue = True

Immediately verify the physical status of the master bedroom window and front door.

Check surveillance footage for the time range 22:21:15 - 22:21:30 to identify if an intruder was visible or if the automation rule malfunctioned.

Temporarily disable any automation rules linking window states to door locks until the cause is resolved.

Verify if there are any motion sensor triggers in the hallway or living room between 22:21:00 and 22:22:00 that might explain the 'Auto' unlock as a safety feature activation.

Cross-reference the 'WindowCovering' event timestamp precision; was the window manually opened by an intruder before the system reacted, or did the system automate it?

FG-04-FP: 低电量报警但传感器仍正常工作

A smoke alarm detected active smoke in the kitchen early morning (06:43 AM) while the house was unoccupied and temperatures were rising abnormally, indicating a potential cooking fire or ignition event.

Explanation: The kitchen smoke alarm transitioned from a battery alert to an active smoke state at 06:43 AM.

Explanation: Occupancy logs confirm the house was empty (all rooms showing Occupancy=0) during the incident timeframe.

Explanation: Temperature sensors show a steady rise in kitchen temperature starting around midnight (2266 -> 2410), suggesting heat accumulation prior to the smoke detection, consistent with an unattended cooking event or smoldering fire.

Explanation: Smoke state cleared by 06:53 AM, but the combination of high temps, empty house, and specific smoke trigger confirms a genuine safety event rather than sensor malfunction.

[2026-06-01T00:30:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2289

Immediately inspect the kitchen for signs of charring, grease fires, or damaged appliances.

Replace the battery in the kitchen smoke alarm as indicated by the prior BatteryAlert.

Check raw sensor readings for 'kitchen_smoke_alarm' around 06:43 AM to determine if the smoke state was transient or persistent.

Verify if any other kitchen sensors (temperature_sensor, cook_surface, smoke_co_alarm) triggered simultaneous alerts at 06:43 AM.

Review the battery voltage history for 'kitchen_smoke_alarm' to confirm if the device was non-functional prior to the smoke alert.

有人在房间且温度上升后趋于稳定（不是持续飙升），无烟雾报警触发

High probability of stealth intrusion indicated by an occupant manually opening the master bedroom window and triggering an automatic front door unlock while all occupancy sensors reported empty rooms.

Explanation: At 22:24:15, the Master Bedroom window coverings were fully opened (100%) despite the occupancy sensor reporting '0' in that room until 22:24:10, suggesting a person entered undetected or manipulated the sensor.

Explanation: Immediately following this (at 22:24:23), the Front Door lock state changed to Unlocked via an 'Auto' source.

Explanation: The timing implies a coordinated sequence where the intruder likely triggered the smart home's 'Leave Home' or 'Goodnight' routine remotely after gaining access through the window, thereby unlocking the main entrance for exit or further entry.

Explanation: Manual lock operations occurred earlier in the day at occupied times, confirming residents usually lock/unlock manually; the sudden switch to 'Auto' at night with zero occupancy is anomalous.

Occupancy logs showing '0' in all rooms between 22:24:10 and 22:24:27

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

Do not enter the property until police have secured it.

Check video recordings from exterior cameras if available to identify the suspect.

Review smart home automation logs to understand why the 'Auto' unlock was triggered without a valid user presence.

[2026-06-03T07:34:21] front_door_lock | DoorLock.LockState = 2

[2026-06-03T07:34:28] front_door_lock | DoorLock.LockState = 1

[2026-06-03T16:08:00] front_door_lock | DoorLock.LockState = 2

Verify if the 'Auto' source for the front door unlock is triggered by a smart home routine (e.g., 'Goodnight' mode) or an external signal.

Cross-reference with camera feeds (if available) for the entrance and master bedroom windows at 22:24.

Check if the window cover motor log shows manual override commands vs. scheduled automation.
