疑似尾随入侵警报，建议住户确认是否有同行人

High-probability forced entry or tailgating attempt detected via unauthorized lock manipulation and immediate door opening during a period of confirmed zero occupancy.

Explanation: Occupancy sensors confirmed the house was empty (0) at 18:05:00, yet a manual lock operation occurred at 18:06:00 with an unusual source code (3).

Explanation: Immediately following the lock command at 18:06:00, the front door contact sensor registered as OPEN (False) within 2 seconds, indicating the door was physically manipulated despite being locked.

Explanation: The sequence shows a rapid 'Lock -> Open' cycle, consistent with testing a lock override, breaking in, or forcing the latch while the system attempted to secure it.

[2026-06-12T18:05:00] entrance_occupancy | OccupancySensing.Occupancy = 0

[2026-06-12T18:06:02] front_door_contact | StateValue = False

Immediately alert local authorities and provide the timestamped log evidence of the unauthorized access attempt.

Remotely disable the smart lock features for all users until physical inspection confirms the device integrity.

Dispatch a security team or trusted neighbor to perform an immediate physical sweep of the entrance area.

Evidence indicates an unauthorized entry attempt followed by a forced or anomalous auto-lock cycle at the front door while the system was in 'Away' mode.

Explanation: The home occupancy sensors reported '0' (empty) for the entire night and early morning, indicating the residents were away (vacation mode).

Explanation: At 07:26:17, the front door lock received a manual operation command, but this occurred while no one was present inside the house to perform it.

Explanation: Immediately after the manual interaction, the door contact sensor toggled (False then True), suggesting the door was opened/closed physically.

Explanation: Critically, the lock state transitioned to 'Unlocked' (1) via an 'Auto' source at 07:26:23 without a preceding explicit unlock log, implying the lock logic may have been compromised or overridden during the physical intrusion event.

All room occupancy sensors report '0' starting from 00:00:00

Immediately notify law enforcement of a potential break-in at the specified address.

Dispatch security personnel to the scene to verify the status of the door and check for signs of forced entry.

Temporarily disable automated locking features on the smart lock to prevent further manipulation until hardware is inspected.

疑似尾随入侵警报，建议住户确认是否有同行人

Evidence indicates a coordinated unauthorized access attempt involving an unknown external source unlocking the front door followed by automated window opening to facilitate entry.

Explanation: The log shows a LockOperation from 'Source=3' (unknown/external) at 17:26:00, which is distinct from legitimate Manual or Auto sources seen in previous logs.

Explanation: Immediately following this suspicious unlock event, the master bedroom window was fully raised (100%) at 22:14:24, coinciding with another door unlock sequence initiated by 'Auto' source but preceded by the occupancy sensor detecting presence inside the room at 22:14:14.

Explanation: The sequence of events (Unknown Source Unlock -> Occupancy Detected -> Window Opened -> Door Unlocked again) deviates significantly from standard scheduled routines and suggests an active intrusion scenario.

[2026-06-08T22:14:24] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

[2026-06-08T22:14:14] master_bedroom_occupancy | OccupancySensing.Occupancy = 1

Dispatch security personnel to verify physical access status and secure premises immediately.

Review camera footage for the front entrance and master bedroom windows between 17:25 and 22:15 to identify intruder activity.

Audit authentication logs for 'UserIndex=1' and 'Source=3' to determine if credentials were compromised or if the device was physically tampered with.

An unauthorized user (UserIndex=3) manually unlocked and opened the front door at 18:46 while all internal sensors reported zero occupancy, indicating a likely break-in attempt or successful entry by an intruder.

Explanation: At 18:46:00, a LockOperation event occurred with OperationSource=3 and UserIndex=1, which deviates from standard resident behavior profiles seen at 07:19 and 18:02.

Explanation: Immediately following this operation (18:46:02), the front_door_contact sensor triggered (StateValue = False), confirming the door was physically opened.

Explanation: Crucially, occupancy sensors for the entrance, living room, master bedroom, second bedroom, bathroom, and kitchen all reported '0' (empty) during this exact timeframe, suggesting no authorized resident was present to perform a routine departure/arrival action.

[2026-06-11T18:46:02] front_door_contact | StateValue = False

All occupancy logs between 18:45 and 18:47 show Occupancy = 0

Dispatch security personnel immediately to the residence location.

Review video footage from the front door entryway between 18:40 and 18:50 to identify the suspect.

Check internal motion sensors upon arrival to determine if the intruder has already exited or is still inside.

A remote entity (UserIndex=3) successfully unlocked the front door and entered the home without a manual unlock event or resident presence at the entrance, suggesting stolen credentials or relay attack.

Explanation: Timestamp analysis reveals a gap between the last known resident activity (16:34 Manual Lock) and the next lock state change (17:06 Unlock), with no entry/exit sensor triggers in between.

Explanation: The log shows an 'Unlock' event at 17:06 originating from 'OperationSource=3' with 'UserIndex=1', which contradicts standard behavior where Source=3 (likely external/app) should not trigger a direct unlock unless authorized by a physical key or spoofed token.

Explanation: Crucially, the 'entrance_occupancy' sensor remained at 0 during this window, yet the lock state changed to Unlocked (State=1) and the contact sensor did not trigger an immediate exit, implying someone walked through while the system failed to register the entry or the user bypassed the sensor.

No 'entrance_occupancy' = 1 log entry between 16:34 and 17:06 despite the lock changing state.

Immediately force-lock the front door via the app or smart home hub.

Revoke all active access tokens for UserIndex=1 and reset the smart lock PIN/code immediately.

Review network logs for MAC address spoofing attempts around 17:06.

Dispatch security personnel to verify if anyone has accessed the premises since 17:06.

[2026-06-05T07:23:28] front_door_lock | DoorLock.LockState = 1

Window covering fully closed (100%) at 22:41 coincides exactly with the front door unlocking, suggesting potential coordinated access or environmental tampering, though less direct than the lock issue.

[2026-06-05T22:41:20] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

LockState transition from Locked (2) to Unlocked (1) at 22:41 without a corresponding Manual Unlock operation log, only an Auto source log which occurred earlier at 22:41:24 for a different event type or timing discrepancy.

UserIndex=1 performing a LockOperation while the door was already locked (State=2), potentially indicating a relay attack or spoofed signal if UserIndex is external.

Timestamp precision between 'LockOperation' events and 'DoorLock.LockState' changes to rule out logging delays.

MAC address or device ID associated with 'OperationSource=3' and 'UserIndex=1' to verify if it matches a registered household member's device.

Battery voltage of the front_door_lock to rule out low-battery false states.

Network traffic logs around 22:41 to check for unusual connection attempts to the smart lock API.

Confirmed unauthorized entry at 07:19 and 18:04 where occupancy sensors were triggered by an unknown person who manually unlocked the door, despite the house being empty.

Explanation: House was in a confirmed 'empty' state (all occupancy sensors = 0) prior to both incident times.

Explanation: At 07:19:11 and 18:04:02, entrance/adjacent occupancy sensors registered presence ('Occupancy = 1') immediately preceding or coinciding with manual lock operations.

Explanation: The sequence shows an entity entering (occupancy spike), manually unlocking/interacting with the door, leaving (contact opens then closes), and triggering auto-lock, which contradicts normal automated behavior for an empty home.

Explanation: No evidence of authorized user activity correlates with these specific timestamps.

[2026-06-24T07:19:11] entrance_occupancy | OccupancySensing.Occupancy = 1 followed by Manual Lock

[2026-06-24T18:04:02] front_door_contact | BooleanState.StateValue = False (door opened) after previous occupancy event

Immediately verify if residents are safe inside the property.

Review CCTV footage covering the front entrance and hallway between 07:15 and 07:25, and 18:00 and 18:10.

Check access logs for the smart lock to identify if the manual unlock originated from a stolen credential or physical key usage rather than an authorized app command.

Contact local authorities if no explanation is provided within 30 minutes.

[2026-06-24T18:04:00] front_door_lock | DoorLock.LockState = 2

[2026-06-24T21:52:37] front_door_lock | DoorLock.LockState = 1

Verify the source IP address or device ID associated with the 'Manual' lock operations to determine if they originated from a registered user's phone/app or an unknown device.

Cross-reference the timestamp with the 'room_activity' count for the entrance; a spike in activity would support the anomaly hypothesis.

The system logs indicate a standard morning departure routine; the 'anomaly' regarding the 07:27 manual unlock was a false positive caused by a delayed occupancy sensor reading, and the midnight zero-occupancy readings are consistent with residents sleeping.

Explanation: The 07:27 sequence shows the door contact sensor (front_door_contact) went False immediately after manual unlock, confirming the door opened normally without forced entry or lingering open states.

Explanation: Occupancy sensors at Entrance and Living Room registered presence at 07:27:23 and 07:27:24 respectively, proving legitimate users were present and moving through the home rather than an intruder.

Explanation: The repeated zero-occupancy readings from 00:00 to 05:00 align perfectly with typical human sleep cycles and are corroborated by the absence of any motion events or lock manipulations during those hours.

[2026-06-10T07:27:24] entrance_occupancy | OccupancySensing.Occupancy = 1

[2026-06-10T22:11:38] front_door_lock | DoorLock.LockState = 1

System-wide occupancy sensor synchronization failure or data loss around midnight to 1 AM.

Uniform timestamp pattern starting exactly at 00:00:00 for all rooms showing Occupancy = 0.

Repetition of this exact pattern at 00:30:00 across multiple rooms.

Living room and master bedroom data ceasing after 01:00:00 in the provided list, suggesting a gap or reset.

No explicit error codes regarding sensor hardware failure are listed in the packet; it may simply reflect everyone sleeping at once with sensors calibrated to report 0 when static.

Sequence at 07:27:21 - 07:27:24: Manual Unlock followed by immediate Auto Lock without intermediate occupancy confirmation in the signal list.

Synchronized zero-occupancy reads across all bedrooms and living areas at 00:00:00 and 00:30:00, potentially masking movement.

Check `front_door_contact_sensor` status between 07:27:20 and 07:27:30 to verify if the door remained open longer than expected or if there was forced entry vibration.

Verify `living_room_occupancy` and `entrance_occupancy` timestamps immediately preceding 00:00:00 to determine if sensors stopped reporting or if a hard reset occurred.

Cross-reference `front_door_lock` operation source IP/MAC addresses for the 07:27:21 Manual operation to confirm if it originated from inside the network (legitimate user) or external access.

Review `security_system` global state logs for any arming/disarming events correlated with the 07:27 incident.

The front door lock exhibits a critical logic failure where it immediately re-unlocks itself via 'Auto' source exactly 8 seconds after being manually locked, creating an unsecured window of opportunity.

Explanation: Analysis of the raw log shows a manual lock event at 07:12:26 followed immediately by an 'Auto' unlock event at 07:12:34.

Explanation: Crucially, the door contact sensor confirms the door was physically open (StateValue=False) between 07:12:28 and 07:12:33, verifying the system allowed entry during this interval.

Explanation: Unlike the evening incident which correlates with occupancy changes, the morning incident occurs while all sensors report zero occupancy for hours, indicating no resident initiated the auto-unlock, pointing to a hardware or firmware malfunction rather than user behavior.

[2026-06-25T07:12:28] front_door_contact | BooleanState.StateValue = False

Immediately force-lock the physical front door from inside the home and verify the latch is engaged.

Replace the front door lock actuator or reset the lock's firmware configuration to disable the automatic unlock feature pending investigation.

Review network logs for any unauthorized remote commands sent to the lock device around 07:12:34.

Critical fire hazard detected: kitchen temperature rose steadily from ~22°C to over 240°C (indicating extreme heat or combustion) for nearly 5 hours while the house was unoccupied, triggering the smoke alarm.

Explanation: The kitchen temperature sensor recorded a continuous and significant rise in temperature from 22.64°C at 00:00 to 243.9°C by 05:00, which is physically impossible for normal cooking or appliance standby and indicates active combustion or severe equipment failure.

Explanation: The house occupancy sensors confirmed zero occupants throughout the entire incident window (00:00 to 07:21), meaning no one was present to detect or extinguish the fire source manually.

Explanation: The smoke alarm triggered at 01:22, exactly correlating with the period where temperatures exceeded 230°C, confirming the presence of smoke/combustion products.

Explanation: The lack of door contact sensor interruptions during the night rules out forced entry as the primary cause, pointing instead to an internal event like unattended cooking igniting or electrical arcing.

中等可信度警报，建议住户确认是否本人操作

An unauthorized or compromised entity (UserIndex=1) locked the door from the inside at night while the house was unoccupied, immediately followed by a suspicious automatic unlock event.

Explanation: At 2026-06-30T19:59:00, an operation with 'OperationSource=8' and 'UserIndex=1' locked the front door while occupancy sensors indicated the home was empty (living_room_occupancy = 0).

Explanation: The subsequent state change at 21:48:36 shows the door unlocking ('LockState=1') triggered by 'OperationSource=Auto', occurring exactly when the entrance sensor detected presence (transitioning to True at 21:48:35), suggesting an intruder entered and triggered the auto-lock/unlock cycle.

Explanation: This behavior contradicts standard manual exit routines and indicates either a credential theft scenario where UserIndex=1 is a compromised account, or a spoofed command leading to physical access.

[2026-06-30T21:48:35] front_door_contact | BooleanState.StateValue = True

Immediately reset the smart lock credentials and force a factory reset if possible.

Check the security camera footage for the time range 19:50-22:00 to identify the person entering the property.

Audit all accounts associated with 'UserIndex=1' and revoke active sessions on other devices.

Update the smart lock firmware to patch any potential vulnerabilities allowing remote 'Auto' source manipulation.

A manual lock attempt occurred immediately after occupancy was detected at the entrance, followed by a door contact sensor transition indicating the door was opened and then closed, suggesting an unauthorized person entered before the resident locked up.

Explanation: Occupancy sensor at the entrance registered presence (1) at 07:33:08.

Explanation: Exactly 3 seconds later at 07:33:11, a manual lock operation (Type 1) was triggered.

Explanation: Door contact sensors show a transient state change between 07:33:13 (False/Open) and 07:33:15 (True/Closed), confirming the door cycle involved opening.

Explanation: The sequence implies someone occupied the entryway, manually locked the door (potentially trapping themselves or simulating an entry), and then the system auto-locked shortly after, consistent with a tailgating or forced entry scenario rather than a standard automated routine.

A manual lock engagement occurred at midnight when all occupancy sensors reported zero, followed by an automatic unlock 30 minutes later, strongly suggesting a tailgating attempt or unauthorized physical interaction with the door while the house was unoccupied.

Explanation: At 00:00:00, all room occupancy sensors (living_room, master_bedroom, second_bedroom, bathroom, entrance) consistently reported Occupancy = 0, indicating no one was inside to manually operate the door.

Explanation: Contrary to normal automated schedules seen at 07:26 and 21:59 where locks are engaged after occupancy detection, a 'Manual' lock operation event was recorded exactly at 00:00:00.

Explanation: The immediate sequence of Manual Lock -> Auto Unlock within 30 minutes without any subsequent human presence suggests an external actor manipulated the lock mechanism (potentially via smart lock override, magnetic sensor spoofing, or physical force on a connected device) before leaving.

[2026-06-30T00:00:00] ... OccupancySensing.Occupancy = 0 (All rooms)

Immediately check physical security logs for the smart lock brand/model to determine if it supports remote access or magnetic tailgating bypasses.

Review network traffic logs around 00:00:00 for any connection attempts from unknown IP addresses to the lock's gateway.

Temporarily disable automatic unlocking features and require explicit user authentication for any future door operations until the cause is verified.

[2026-06-30T21:59:37] front_door_lock | DoorLock.LockState = 1

The presence of a Manual operation at 00:00:00 (midnight) which is unusual for a standard automated schedule if no one is home, especially when combined with immediate Auto unlocking.

High event count (1655) suggests potential sensor noise or malicious scanning rather than just routine automation.

Front door manual lock state change (Locked -> Unlocked sequence) occurring exactly at 00:00:00 with zero occupancy in all rooms.

Immediate subsequent 'Auto' unlock event at 00:30:00 without any prior occupancy detection triggering it naturally.

Discrepancy between Manual interaction source and the lack of human presence indicators in the house.

Timestamp accuracy synchronization between the front-door-lock device and all occupancy sensors to rule out clock skew causing false negatives.

Raw binary data or detailed event flags for the 00:00:00 Front Door Lock event to determine if 'Manual' was triggered by an external physical force (tailgating) vs. a key fob/app command from an unknown device ID.

Network connection logs for the front-door-lock IP address at 00:00:00 to check for unusual handshake patterns or unauthorized access attempts.

History of previous events around 00:00:00 to see if this is a recurring anomaly or a one-time breach.

Unauthorized physical entry attempt at the front door between 17:56 and 17:57, evidenced by occupancy detection followed immediately by a manual lock operation that failed to secure the door (LockState=2) while the contact sensor remained open.

Explanation: Occupancy sensor detected presence in the entrance area at 17:56:03, which was not present prior to this time.

Explanation: At 17:57:00, a Manual LockOperation occurred, but the DoorLock.LockState transitioned to 2 (Unlocked/Open), indicating the locking mechanism failed or was bypassed despite the user attempting to lock.

Explanation: The front_door_contact sensor remained False (Open) from 17:57:02 until 22:50:33, confirming the door was left physically compromised for over 4 hours before an Auto-lock attempt finally closed it.

[2026-06-19T17:56:03] entrance_occupancy | OccupancySensing.Occupancy = 1

[2026-06-19T17:57:02] front_door_contact | BooleanState.StateValue = False

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

Secure all other doors and windows, and do not re-enter until police confirm safety.

Preserve the smart lock device for forensic analysis to determine if the mechanical jamming was caused by force or credential misuse.

[2026-06-19T07:22:31] front_door_lock | DoorLock.LockState = 2

[2026-06-19T07:22:39] front_door_lock | DoorLock.LockState = 1

[2026-06-19T16:21:00] front_door_lock | DoorLock.LockState = 2

High frequency of lock state changes (8 total events in short span) suggesting mechanical struggle rather than smooth electronic operation.

LockState transition to '2' (likely unlocked/opened) at 17:57 without an accompanying 'Unlock' event from a known source, followed by occupancy sensors reporting empty rooms shortly after.

Sequence of Manual Lock -> Auto Unlock at 22:50 immediately followed by DoorState changing to '1' (Locked), which may indicate a failed locking attempt or sensor glitch post-breach.

Absence of occupancy data between 17:57 and 22:50 while the front door is manipulated multiple times.

Timestamps and MAC addresses/IPs associated with the 'Manual' lock operations to verify if they originate from resident devices or unknown external attempts.

Door contact sensor logs around 17:57:00 to confirm if the door was physically opened beyond the threshold that triggered the 'LockState=2' change.

Motion sensor logs specifically for the Entrance hallway between 17:57 and 22:50 to detect any presence despite the system reporting no occupancy in other rooms.

Power consumption spikes on the smart lock device during the 17:57 and 22:50 intervals to distinguish between normal key-turning torque and forced jamming.

洗碗机运行期间厨房漏水传感器触发 两个事件的时间关联性

An unauthorized entry attempt was detected at the front door during nighttime hours, evidenced by the door contact opening immediately followed by an automatic lock re-engagement.

Explanation: The raw log shows 'front_door_contact' state changed to True (door opened) at 22:52:30.

Explanation: Exactly one second later at 22:52:31, a LockOperation occurred with 'OperationSource=Auto', indicating the system attempted to secure the door without human intervention.

Explanation: This sequence, combined with zero occupancy in all other rooms and no preceding manual unlock commands, strongly suggests a forced entry or tailgating event rather than authorized access.

[2026-06-13T22:52:30] front_door_contact | BooleanState.StateValue = True

Dispatch security personnel or emergency services to the location immediately.

Review camera footage for the front door between 22:52:20 and 22:53:00 to identify intruders.

Forcefully disarm the smart-lock automation rules temporarily to ensure future physical access is not overridden automatically.
