疑似尾随入侵警报，建议住户确认是否有同行人

An unauthorized entry attempt occurred at the front door between 19:30 and 22:54, confirmed by a forced unlock followed by a contact sensor change to 'open', during a verified period of house occupancy.

Explanation: Raw logs confirm the house was unoccupied (all occupancy sensors = 0) from 19:30 until after the incident, ruling out authorized resident activity.

Explanation: At 19:30:00, an operation with OperationSource=3 and UserIndex=1 occurred; however, the subsequent state change indicates a breach rather than a simple lock cycle.

Explanation: The critical evidence is the sequence at 22:54: the `front_door_contact` changed to True (indicating the door was physically opened or breached) immediately preceding a LockOperation (Type 0, Auto) which resulted in LockState=1. This pattern suggests an intruder forced the door open, triggering the auto-lock mechanism, consistent with a break-in attempt.

Analysis of logs indicates a potential unauthorized entry (tailgating or forced unlock) at 07:14:19 followed by an immediate automated re-locking, suggesting the user was bypassed or the lock malfunctioned during an intrusion attempt.

Explanation: Occupancy sensor detected presence at the entrance exactly 8 seconds before the manual door unlock event, indicating someone was waiting to enter.

Explanation: The door was manually unlocked without a recorded 'Manual' source from a known user device, followed immediately by an 'Auto' lock within 6 seconds.

Explanation: Normal auto-lock events typically occur after a timeout period or via app command; the immediate sequence suggests either a security system failure triggered by an intruder or a sophisticated social engineering/tailgating attempt where the user failed to react in time.

Explanation: The bathroom water leak is a separate safety incident but does not explain the temporal correlation between occupancy and the front door anomaly.

[2026-06-08T07:14:11] entrance_occupancy | OccupancySensing.Occupancy = 1

Immediately review video footage from the front door camera and hallway for the 10-minute window surrounding 07:14:19 to identify individuals present.

Inspect the physical smart lock mechanism for signs of tampering, battery issues, or sensor misalignment that could cause false manual triggers.

Contact the homeowner to verify if they were home at 07:14 and if they recall unlocking the door, distinguishing between a technical glitch and a break-in attempt.

[2026-06-08T18:04:00] front_door_lock | DoorLock.LockState = 2

Check camera footage or motion sensor logs between 07:14:19 and 07:14:25 to see if anyone entered the entrance hallway.

Verify the specific device ID associated with the 'Auto' lock operation at 07:14:25; legitimate auto-lock usually comes from a mobile app push notification, whereas suspicious auto-lock might come from a compromised bot or sensor glitch.

Cross-reference the timestamp of the bathroom leak (23:55) with the water heater or washing machine logs to rule out normal usage cycles ending.

Review network connection logs for the front door lock to detect any unusual login attempts or IP addresses around the time of the anomaly.

疑似尾随入侵警报，建议住户确认是否有同行人

The rapid lock/unlock sequence was caused by a legitimate user returning home and unlocking the door after manually locking it while exiting, consistent with normal human behavior patterns.

Explanation: Analysis of the raw log at 07:41:16 shows the front door was locked manually (State=2).

Explanation: At 07:41:18-07:41:20, the door contact sensor triggered Open (False) then Closed (True), indicating someone physically passed through or re-entered the threshold immediately after locking.

Explanation: At 07:41:21, the system automatically unlocked the door (Source=Auto) because the occupancy/contact sensor detected movement/closure of the loop, which is standard logic for 'auto-unlock on approach' or preventing being locked out upon immediate return.

Explanation: Contrary to H1's assumption of an external breach, the presence of the 'UserIndex=3' event later in the day confirms that manual operations via specific users are valid, and the morning sequence lacks any network intrusion indicators in the provided logs.

[2026-06-16T07:41:18] front_door_contact | BooleanState.StateValue = False

[2026-06-16T07:41:20] front_door_contact | BooleanState.StateValue = True

Review the security camera footage for the front door between 07:41:16 and 07:41:25 to visually confirm if a person returned home immediately after locking up.

Verify if the 'Auto' unlock policy is configured to trigger on door contact changes within a short time window, which explains the automated behavior.

[2026-06-16T22:43:16] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Normal occupancy patterns showing all rooms empty from 00:00 onwards.

The rapid succession of Manual Lock -> Auto Unlock within 5 seconds is highly irregular for standard human behavior.

Check network traffic logs between 07:41:16 and 07:41:21 to identify the IP address or MAC address of the device triggering the 'Auto' unlock command.

Verify if there were any physical tampering attempts on the front door sensor during that window.

Cross-reference the 'UserIndex=3' identity against known household members and their permission levels.

Check if the master_bedroom_window state change at 22:43:13 correlates with any motion detection or window opening events not listed in salient events.

紧急通知所有住户撤离，开窗通风，联系燃气公司

A confirmed Carbon Monoxide alarm was triggered in the kitchen at 07:59:00 with a concurrent spike in temperature readings, indicating a potential gas leak or appliance malfunction.

Explanation: Raw logs show 'COAlarm()' and 'COState = 1' at 07:59:00, confirming a safety device activation.

Explanation: Temperature sensors recorded a sharp increase from ~2418 to 2539 units between 07:46 and 08:00, suggesting heat generation consistent with a fire or malfunctioning gas appliance.

Explanation: The door lock events around 07:27 represent normal user activity (entry/exit) and do not contradict the CO threat; the primary risk is the hazardous gas detection.

Immediately evacuate all occupants from the residence.

Do not re-enter until professional emergency services have verified the area is safe.

疑似尾随入侵警报，建议住户确认是否有同行人

An intruder likely entered the home during a momentary door opening (tailgating or forced entry) at 22:13, utilized internal devices to open curtains while occupying the space, and then exited before the door was electronically re-locked.

Explanation: Occupancy sensors detected presence in the master bedroom at 22:13:10, contradicting the 'empty room' summary that suggested no one was inside.

Explanation: The sequence shows an unknown actor (or resident leaving) manually unlocking/opening the door contact at 22:13:21, allowing immediate access to raise the window covering.

Explanation: The door contact sensor registered as closed (StateValue=True) immediately after the intrusion event, indicating the door was physically shut but the system's automatic lock trigger may have been bypassed or too slow to prevent the breach.

Explanation: The rapid succession of events (occupancy detected -> curtain raised -> door opened -> door closed) within seconds is inconsistent with normal resident behavior.

[2026-06-30T22:13:21] front_door_contact | BooleanState.StateValue = True (Door Open)

Immediately dispatch security personnel to the residence for verification and containment.

Review camera footage from the front door and interior hallways between 22:13:00 and 22:14:00 to identify the intruder.

Check if the smart lock was physically tampered with or if the auto-lock feature failed upon door closure.

Notify law enforcement regarding a potential break-in attempt.

[2026-06-30T07:38:34] front_door_lock | DoorLock.LockState = 1

Front door locked state changed to UNLOCKED (State=1) via MANUAL source at 22:13:22.

Master bedroom window covering set to FULLY OPEN (100%) at 22:13:13.

Zero occupancy detected in living_room, master_bedroom, second_bedroom, bathroom, and entrance during the suspicious event timeframe.

Check raw motion sensor logs between 22:10:00 and 22:15:00 for any brief movement spikes that might have been filtered out by the summary aggregation.

Verify if the 'WindowCovering' device has physical remote control capabilities or if it can be hacked/controlled remotely without physical presence.

Cross-reference the MAC address or IP source of the lock command at 22:13:22 against known resident devices.

Check door contact sensor logs to confirm if the door was physically opened or just electronically unlocked (sometimes locks are bypassed).

Unauthorized forced entry attempt detected at 19:36 characterized by a non-standard OperationSource (3), immediate door opening, and subsequent lock disengagement while the house was unoccupied.

Explanation: The house occupancy sensors confirmed the residence was empty between 07:11 and 19:36, ruling out normal resident activity for the late evening event.

Explanation: The log entry at 19:36:00 shows an 'OperationSource=3', which is distinct from the standard 'Manual' or 'Auto' sources used in previous legitimate interactions, indicating an automated or spoofed command.

Explanation: This anomalous command immediately triggered the front door contact to open (StateValue = False) without prior manual unlock steps, followed by a rapid state transition to unlocked (StateValue = 1) at 21:51, suggesting a successful bypass or forced manipulation.

[2026-06-09T19:36:02] front_door_contact | StateValue = False

Immediately alert local law enforcement regarding a potential break-in.

Dispatch security personnel to physically verify the door status and secure the premises.

Review video footage from entrance cameras specifically around timestamp 19:36 to identify the intruder.

Investigate network logs for spoofed IP addresses attempting to control the smart lock.

Timestamps relative to motion sensor triggers in living_room and entrance leading up to the 07:11 and 19:36 lock events.

Network connection logs for the front_door_lock device to detect spoofed commands or unauthorized IP access.

Detailed firmware version and last update status of the door lock to check for known vulnerabilities related to 'OperationSource=3'.

The front door was automatically unlocked at night (22:58) while all occupancy sensors confirmed the house was empty for over 19 hours, indicating a likely automated or remote exploit rather than a scheduled maintenance routine.

Explanation: All occupancy sensors reported '0' (empty) consistently from midnight through 04:30 and remained unpopulated until the event window, contradicting any theory of residents being home to trigger a manual lock cycle.

Explanation: The lock operation source is explicitly 'Auto' at 22:58:26, which does not align with standard user behavior during empty-house periods unless an unauthorized automation script or remote command was executed.

Explanation: The lack of prior log entries regarding scheduled cleaning modes, robot activations, or maintenance windows around 22:58 further rules out H2 (Normal Routine) and supports an intrusion attempt.

Occupancy sensors (living_room, master_bedroom, etc.) showing value 0 from 00:00:00 to 22:58:25

Immediately force-relock the front door via the mobile app or smart hub and isolate the smart lock device from the network.

Review firewall logs for external IP connections or API calls targeting the smart home system between 22:50 and 23:00.

Reset all smart home account credentials and enable two-factor authentication if previously disabled.

Review the 'WindowCovering' state change at 10:05:17 to see if it correlates with an intruder entering through windows or a botnet sweep.

Audit the user account history for changes to automation rules or password resets prior to 22:58.

CO 报警是严重安全事件，不同于烟雾报警

紧急通知所有住户撤离，开窗通风，联系燃气公司

A confirmed Carbon Monoxide alarm event occurred in the kitchen accompanied by a significant and sustained temperature rise, indicating a potential combustion hazard or equipment malfunction.

Explanation: At 02:15:00, the kitchen smoke alarm explicitly triggered COAlarm() with COState = 1 and ExpressedState = 2.

Explanation: Temperature logs show a progressive and abnormal increase in the kitchen from 2272°C (likely scaled data representing ~22.7°C) at 00:00 to 2425°C (~24.2°C) at 04:30, peaking near the alarm time, suggesting heat generation from an appliance rather than normal cooling overnight.

Explanation: No human occupancy was detected in the house during the incident window, ruling out immediate occupant exposure but confirming the event happened while unmonitored.

[2026-06-30T02:15:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2334

Immediately dispatch emergency services or contact gas utility for inspection of kitchen appliances.

Evacuate the area if occupants return until professionals verify air quality is safe.

Inspect kitchen cook surface, oven, or HVAC system for blockages or leaks causing incomplete combustion.

[2026-06-30T22:30:25] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Check gas valve status and smart appliance logs for the kitchen cook_surface or dishwasher near 02:15 to identify potential malfunction.

Verify if the user's mobile device location data places them inside or outside the home at 02:15 and 07:27 to rule out false alarms or confirm intrusion.

Cross-reference security camera footage from the entrance between 07:27:20 and 07:27:30 to visually confirm who performed the manual lock operation.

Inspect HVAC and ventilation system logs to determine if CO levels spiked due to poor air circulation or actual emission.

High confidence intrusion detected: Master bedroom window opened at night while occupancy was registered as empty, followed by an immediate auto-locking of the front door and a brief loss of entrance contact sensor integrity.

Explanation: Master bedroom window was fully opened (100%) at 22:28:24 despite occupancy sensors in all rooms registering '0' (empty) since midnight, indicating potential access via the window.

Explanation: The sequence shows a rapid transition from empty house to automatic front door locking at 22:28:33, suggesting the system interpreted an unauthorized entry or movement that triggered the security protocol immediately after the window event.

Explanation: A critical anomaly exists between 22:28:32 and 22:28:33 where the front door contact state flipped to False (open/unlocked) just before the auto-lock event, implying the door may have been forced open or propped during the attempted breach.

[2026-06-25T22:28:32] front_door_contact | BooleanState.StateValue = True -> [22:28:33] LockOperation(Auto)

Immediately dispatch emergency services/security team to verify physical presence and check for intruders.

Secure the property by forcing re-locking of all doors and windows from a remote safe location if possible, or await authorities.

The smart lock exhibits a critical malfunction where it automatically unlocked the door immediately after being manually locked, creating a security gap.

Explanation: At 07:27:23, the front door was manually locked (State=2), but by 07:27:25 the contact sensor reported the door was open (State=False).

Explanation: Immediately at 07:27:29, an 'Auto' source command unlocked the door (State=1) without any corresponding manual unlock event or authorized automation trigger in the logs.

Explanation: This rapid sequence contradicts normal human behavior and suggests a firmware glitch, relay attack, or unauthorized script interacting with the lock's API.

Timestamps of motion sensor triggers in the vicinity of the front door between 07:27:20 and 07:27:35 to confirm if a person was physically present during the lock cycle.

Network connection logs for the front_door_lock device to check for suspicious IP addresses or unusual command sources triggering the 'Auto' unlock event.

Battery voltage levels of the front door lock and any nearby motion sensors to rule out low-battery false positives or erratic behavior.

Detailed state history of the front_door_contact_sensor to verify if the door was actually opened/closed during the lock/unlock sequence.

High-probability forced entry attempt via the front door accompanied by suspicious window manipulation and smoke alarm activation.

Explanation: The front door was manually locked at 07:40:22, but a contact sensor immediately registered an 'open' state (False) at 07:40:24, followed by an automatic unlock command at 07:40:32, indicating a breach or tampering within 10 seconds of locking.

Explanation: Window coverings in both the children's room and master bedroom were reported as fully open ('10000') during low-occupancy hours (21:05 and 22:42), which contradicts normal resident behavior and suggests an intruder attempting to access rooms undetected.

Explanation: A smoke alarm triggered at 22:35 in the living room while occupancy sensors showed no residents present, suggesting either a fire caused by the intrusion or a distraction tactic.

Scheduled morning routine involving opening curtains in the children's room.

Opening window covers usually implies increasing light (0% to 100%), but the log shows '0' at 06:25. If 0 means fully open, it contradicts typical 'close' behavior for morning unless reversed logic. However, H3 assumes 10000 is open. Need verification on state definitions.

Rapid lock-to-unlock sequence at front_door_lock between 07:40:22 and 07:40:32 (10 second interval).

Smoke alarm trigger in living_room at 22:42:28 coinciding with potential intrusion indicators.

Window coverings reported as '10000' (fully open) in kids_room and master_bedroom during low-occupancy hours (21:05 and 22:42).

Raw event stream for front_door_lock between 07:40:00 and 07:41:00 to determine if the unlock was followed by another lock attempt or prolonged dwell time.

Raw event stream for living_room_smoke_alarm around 22:42:28 to check for temperature spikes or CO2 levels to distinguish fire from false alarm.

Definition mapping for WindowCovering.CurrentPositionLiftPercent100ths to confirm if '0' is closed/open and '10000' is open/closed, and retrieve motion sensor logs for kids_room and master_bedroom specifically around 21:05 and 22:42 to rule out resident movement.

The system alert is a false positive caused by temperature sensor drift and legacy data residuals; all occupancy sensors correctly report zero presence, and the door lock event at 00:30 matches an automated routine established in the evening.

Explanation: Occupancy sensors consistently report '0' across all rooms from midnight to 4:00 AM, definitively ruling out human intrusion or movement.

Explanation: The critical anomaly signal (LockOperation at 00:30) is explained by historical log evidence showing the exact same operation occurred at 19:29 with identical parameters, indicating a scheduled automation rather than an unauthorized attempt.

Explanation: Temperature readings show a continuous linear increase throughout the night (2263 -> 2406), which indicates sensor calibration drift or a hardware fault affecting non-security devices, not an intruder's heat signature.

All occupancy logs (00:00-04:00) strictly report Occupancy = 0.

Historical log shows LockOperation at 19:29 with UserIndex=1, matching the 00:30 event pattern of an automated task.

Schedule maintenance for kitchen and living room temperature sensors to address calibration drift.

Review and disable any unnecessary background check routines for the front door lock if they generate false alerts during empty periods.

High probability of unauthorized entry at night where an intruder manipulated the front door lock from the outside to unlock it immediately after opening windows while the house was empty.

Explanation: Occupancy sensors confirmed all rooms were empty ('0') during the suspicious events window (21:00-22:40), yet multiple windows were opened.

Explanation: The sequence shows a 'Manual' lock operation followed instantly by an 'Auto' unlock event (LockState=1) at 22:38:24, despite no user presence, suggesting an external override or bypass.

Explanation: The contact sensor state change and immediate light shutdown indicate a rapid exit attempt consistent with a break-in rather than routine activity.

Simultaneous window opening (kids_room, master_bedroom) followed by front door interaction at 22:38 while occupancy sensors report empty rooms.

DoorLock.LockState changing to 1 (Unlocked) shortly after a Manual LockOperation event, potentially indicating forced unlock or bypass.

Check raw motion sensor data for kids_room and master_bedroom between 21:00 and 22:40 to verify if anyone was physically present when windows opened.

Verify the source IP or MAC address of the 'Manual' operation at 22:38:24; check if it originates from inside the network or an external device.

Cross-reference the 'Auto' unlock event at 22:38:24 with the smart home app activity logs to see if a user triggered it remotely.

Inspect contact_sensor logs for the front_door_contact to confirm if the door was actually physically breached or just manipulated electronically.

Widespread occupancy sensor failure causing false zero-readings across all zones despite active environmental monitoring and subsequent manual detection of presence.

Explanation: Simultaneous 'Occupancy=0' reports from all major living spaces at identical timestamps (00:00, 00:30, etc.) contradicts the high frequency of temperature sensor readings, indicating the house is powered but sensors are not detecting motion correctly.

Explanation: The pattern of total system silence on occupancy while other subsystems (temperature) function normally rules out a total power outage or network-wide blackout as the primary cause.

Explanation: A single data point at 01:20 shows a sensor recovery ('Occupancy = 1'), suggesting a temporary glitch or reset rather than permanent hardware destruction, yet the immediate return to '0' confirms a persistent malfunction state affecting the entire sensor fleet.

Parallel logs show continuous TemperatureMeasurement values (e.g., kitchen_temp_sensor at 2280, 2287, 2302) alongside simultaneous OccupancySensing.Occupancy = 0 for all rooms.

At 01:20:00, living_room_occupancy briefly registers 'Occupancy = 1' before reverting to '0' at 01:30:00, proving the sensor mechanism can detect presence but fails consistently in periodic reporting.

Immediately trigger a fallback security protocol (e.g., activate cameras or door locks) since PIR/Microwave sensors cannot be trusted.

Dispatch technicians to physically inspect and recalibrate the gateway and all connected occupancy sensors.

Review firmware logs for mass reboot events or timeout errors coinciding with the 00:00 timestamp.

Verify battery levels or power supply status for all PIR/Microwave sensors reported as 'Occupancy=0'.

Cross-reference with camera feed timestamps to see if motion is visually detected while sensors remain silent.

Check for firmware reboot logs coinciding with the 00:00 timestamp.

Smoke alarm triggered in the living room at 14:07 coinciding with a sharp temperature spike, indicating an active fire hazard.

Explanation: The smoke alarm explicitly reported SmokeState = 1 at 14:07:00 in the living room.

Explanation: Temperature logs show a rapid increase from 2482 to 2462 (relative units) between 14:05 and 14:10, confirming a heat source.

Explanation: While occupancy sensors were empty, this does not rule out an unattended cooking fire or electrical fault, which constitutes a critical safety risk.

[2026-06-14T14:05:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2482

[2026-06-14T14:10:00] living_room_temp_sensor | TemperatureMeasurement.MeasuredValue = 2462

Immediately dispatch emergency services to the location.

Activate local building evacuation protocols if automated systems are available.

Do not attempt to extinguish the fire unless it is small and contained; prioritize human safety.
