All occupancy sensors are reporting a stuck '0' state while temperature sensors indicate active heating cycles and system activity, confirming a hardware or firmware failure rather than actual vacancy.

Explanation: Occupancy sensors across all rooms (Living Room, Bedrooms, Entrance, etc.) consistently report '0' from 00:00 to 04:00.

Explanation: Temperature sensors show increasing readings (e.g., Kitchen: 2281 -> 2407), proving the home is powered on and the HVAC system is active.

Explanation: The discrepancy between high system activity (temp changes) and zero occupancy detection indicates the sensors are frozen or misconfigured, not that the house is empty.

Explanation: This creates a false sense of security where the system believes no one is home despite evidence of environmental activity.

[2026-06-20T04:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2407

Immediately notify the homeowner of sensor malfunction via push notification.

Dispatch a technician to inspect, recalibrate, or replace the affected occupancy sensor nodes.

Disable automated arming/disarming logic dependent on these specific faulty sensors until repaired.

[2026-06-20T00:00:00] master_bathroom_occupancy | OccupancySensing.Occupancy = 0

Check battery levels and last heartbeat for all occupancy sensors to rule out power loss.

Inspect raw motion vector data from the last 24 hours to distinguish between 'no movement' vs. 'sensor not detecting movement'.

Verify if any door/window contact sensors triggered recently that would have logically updated an entryway occupancy state.

Cross-reference with smart lock logs to confirm if the home was armed/disarmed around 00:00.

Unauthorized entry detected at 17:49 indicated by door unlock while all internal occupancy sensors reported empty, followed by immediate re-locking.

Explanation: At 17:48:03, the entrance occupancy sensor triggered (Occupancy=1), suggesting someone entered or was near the threshold.

Explanation: At 17:49:00, a manual lock operation occurred resulting in LockState=2, but critically, no subsequent motion was recorded inside any room (Living Room, Master Bedroom, etc.) remained at 0.

Explanation: The sequence of Entrance Occupancy -> Door Unlock -> No Internal Motion strongly implies an intruder entered and left without triggering indoor alarms or motion sensors, a classic 'door-open-no-motion' intrusion pattern.

Explanation: A secondary event at 22:19 shows similar suspicious timing between window adjustment and door state change, reinforcing the pattern of potential unauthorized access attempts.

    "Door unlock event at 17:49


The initial alarm regarding an unlocked front door was caused by a normal automated evening routine and sensor state stabilization, not a security breach.

Explanation: Raw logs show the 'unlocked' state (State=1) at 07:28:26 occurred immediately after an 'Auto' lock operation event, indicating the system's automatic arming sequence or a sensor bounce during the door closing cycle, rather than manual tampering.

Explanation: Contradicts the anomaly hypothesis: The contact sensor transitioned from False (open) to True (closed) within seconds of the state change, confirming the door was physically closed and latched by automation.

Explanation: Contextual verification: Occupancy sensors confirm the house is empty (Occupancy=0) throughout the night until morning activity begins, ruling out unauthorized intrusion.

Check raw GPIO/relay logs for front_door_lock between 07:28:21 and 07:28:26 to see if there was a power cycle, relay bounce, or hidden unlock command not captured in high-level events.

Verify the definition of LockOperationType codes (0 vs 1) and LockState values (1 vs 2) against device firmware documentation to confirm if State=1 truly means 'unlocked' in this context.

Cross-reference front_door_contact_sensor state changes around 07:28 to see if the door was physically opened/closed which might explain the state change without a lock command.

Check motion sensor logs specifically for entrance and living_room between 07:28:21 and 07:28:26 to rule out a person entering/exiting causing the door state fluctuation.

  "what_to_verify


The house is occupied by residents who are actively interacting with smart devices (lights, window coverings) at night; the door unlock and window open events were performed manually by an authorized user.

Explanation: Occupancy sensors confirmed presence in the master bedroom at 22:32:09, immediately preceding the suspicious events.

Explanation: Logs show a resident manually opening the kids' room window at 21:13, establishing a pattern of manual control over window coverings.

Explanation: The front door contact sensor went from False (open) to True (closed) at 22:32:26, followed immediately by an 'Auto' unlock log, indicating the door was opened from the outside (likely by the resident returning home or checking status) rather than forced entry.

Explanation: Residents subsequently turned off lights and continued normal activity, confirming no intrusion occurred.

Time gap between window opening and door unlocking suggests coordinated action or sequence of events

Contact sensor readings for 'entrance' (front_door_contact_sensor) at timestamps 22:32:00 - 22:33:00 to see if door was actually opened before being unlocked.

Motion sensor logs ('living_room', 'dining_room', 'entrance') specifically between 22:30 and 22:40 to detect any human presence triggering movement.

Detailed log of 'front_door_lock' around 22:32 to distinguish between a manual key turn/unlock vs. a smart-lock remote command vs. a mechanical bypass.

Logs for 'kids_room_window' and other windows to check if multiple windows were opened sequentially.

The continuous zero occupancy readings combined with rising ambient temperatures indicate the house is empty and HVAC systems are running normally during nighttime hours, consistent with standard behavior when residents are asleep or away.

Explanation: Occupancy sensors across all rooms (Entrance, Master Bedroom, Living Room, etc.) consistently report '0' from 00:00 to 04:00, confirming no human presence.

Explanation: Temperature logs show a gradual rise in kitchen and living room temperatures (from ~22°C to ~24°C) without any sudden spikes indicative of fire or unattended cooking.

Explanation: The pattern aligns perfectly with a normal scenario where residents have left for the night or are sleeping, rather than an intrusion or sensor malfunction.

Explanation: No evidence of door locks being forced, windows opening, or unauthorized access events is present in the provided logs.

[2026-06-14T00:30:00] living_room_occupancy | OccupancySensing.Occupancy = 0

Lack of context regarding 'room_activity' source; high activity counts without corresponding non-zero occupancy logs could imply sensors are misconfigured or reporting historical data rather than real-time state.

Check the timestamp and value of 'entrance_contact_sensor' and 'entrance_door_lock' status around 00:00 to confirm if the door was opened/closed recently.

Verify the last known 'active' occupancy event for each room to determine when residents actually left or went to sleep.

Cross-reference 'room_activity' event types to see if they correlate with human movement or if they are automated device triggers (e.g., dishwasher cycles, thermostat adjustments).

Check for any 'suspicious_signals' related to door locks being unlocked or windows being open outside the provided list.

The rapid lock/unlock sequence at 07:17 was a scheduled smart-home routine (Auto source) coinciding with the door being physically open due to internal movement, not an intrusion attempt.

Explanation: Occupancy logs show the house was empty from midnight until 06:18, but 'kids_room_occupancy' turned ON at 06:18:00, indicating a resident arrived home before the incident time.

Explanation: At 07:17:27, the front door contact sensor went False (open), then True (closed) within 4 seconds, proving the door was physically manipulated or swung by someone inside.

Explanation: The subsequent 'Auto' unlock command at 07:17:32 is explained by the resident likely triggering a 'Good Morning/Leave Home' automation routine immediately after locking up, which is consistent with normal behavior given the occupancy data.

Explanation: There is no evidence of forced entry; the door state transition aligns perfectly with the presence of a resident inside the home.

Evidence indicates a high probability of an intruder gaining entry via the front door shortly after manipulating bedroom windows, despite zero occupancy readings which suggests sensor failure or bypass.

Explanation: Occupancy sensors in all rooms (including Master Bedroom where window was opened) consistently reported '0' from midnight until 22:41:11, contradicting the presence of an occupant opening curtains and lights at 20:43 and 22:41.

Explanation: A distinct sequence occurred between 22:41:17 and 22:41:23: The master bedroom window was fully opened, followed immediately by the front door contact triggering (state True) and the lock automatically unlocking (Source: Auto).

Explanation: The timing correlation between the window manipulation and the door unlock, combined with the lack of legitimate user activity (lights off, no manual lock/unlock sequence typical of residents), points to an external actor simulating internal automation or exploiting a system vulnerability to gain access.

[2026-06-01T22:41:23] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto)

Continuous OccupancySensing.Occupancy = 0 for all rooms during the event window

Immediately dispatch emergency services/police to the location.

Instruct occupants to evacuate if present or secure themselves inside away from the front door.

Do not attempt to re-lock the door manually if the intruder is still outside; wait for law enforcement.

[2026-06-01T07:29:27] front_door_lock | DoorLock.LockState = 1

Sequence of events: Kids room window fully open (20:43) -> Master bedroom window fully open (22:41) -> Front door unlocked (22:41).

High correlation between window state changes and door lock state changes within minutes of each other.

Zero occupancy reports in all rooms throughout the entire monitoring period (00:00 - end), suggesting no one is currently inside to cause these states, implying remote automation or external tampering.

Correlation between Master Bedroom Window Opening (22:41:17) and Front Door Unlocking (22:41:23) while the house shows zero occupancy.

Multiple instances of windows being opened (Kids Room, Master Bedroom) during low-activity hours without corresponding occupancy data.

Check raw contact sensor logs for Master Bedroom and Kids Room windows to verify if the 'WindowCovering' state change triggered a physical door/window breach alert or if it was just cover movement.

Verify the source IP or device ID associated with the 'Auto' lock unlock event at 22:41:23 to determine if it was a smart-home app command or an unknown signal.

Review motion sensor logs specifically around 20:43 and 22:41 to see if any micro-movements were missed or if sensors were bypassed/disabled.

Check the history of the Window Covering devices to see if they were manually operated by someone outside the home or if there is a scheduled automation rule that triggers at these specific times.

Evidence confirms a forced entry or tailgating event at 06:59 where the door was manually unlocked while the contact sensor indicated the door was open (State=False), followed immediately by auto-locking and occupancy detection.

Explanation: At 06:59:07, the front door lock received a manual unlock command, but the door contact sensor immediately reported 'False' (open state) at 06:59:09, indicating the door was physically open during the unlocking process.

Explanation: Occupancy in the entrance area spiked to 1 at 06:59:10, just as the system auto-locked the door, confirming a person entered the premises via the front door.

Explanation: The sequence of Manual Unlock -> Door Open -> Occupancy Detected -> Auto Lock strongly suggests an intruder gained entry or the resident opened the door for someone without triggering a standard 'lock immediately after close' safety check, constituting a security breach.

Immediately notify the resident (elderly living alone) of the confirmed unauthorized entry attempt.

Contact local law enforcement to file a report regarding the intrusion.

Check with neighbors or building management to see if anyone approached the residence around 06:59 AM.

[2026-06-08T00:00:00] entrance_occupancy | OccupancySensing.Occupancy = 0

Front door manual unlock followed immediately by auto-lock within 3 seconds at 06:59, suggesting potential forced entry attempt or lock malfunction.

Frequent window position toggling (0 to 10000) in the bedroom without clear time-of-day logic (e.g., only opening windows when occupied is not evident).

Check motion sensor logs for the entrance and bedroom specifically around 06:59:00 - 07:00:00 to see if anyone entered before the door was locked.

Verify camera feeds or doorbell logs for the period surrounding 06:59:07 to confirm if the resident was present or if an unknown person approached.

Cross-reference bedroom window events with bedroom light and temperature sensor data to determine if the window state change correlates with human presence or environmental shifts.

No security threat detected; observed events are consistent with automated home routines and resident behavior.

Explanation: The house was unoccupied during the night (00:00-05:30) as confirmed by zero occupancy across all sensors, making an intrusion impossible without entry which would trigger door/window alarms or motion sensors.

Explanation: The window covering changes (closing at 05:31, opening at 12:21, closing at 14:00) occurred either before the resident woke up/entered (automated morning routine) or while they were present in other rooms, contradicting the theory of an undetected intruder manipulating them silently.

Explanation: The door lock sequence shows a manual lock upon departure, followed immediately by an 'Auto' unlock (likely a safety check or system glitch that did not compromise security), and a final manual re-lock, indicating normal user control rather than forced entry.

[2026-06-24T07:01:00] bedroom_occupancy | OccupancySensing.Occupancy = 1 (Resident awake before curtain closure)

Occupancy sensors remained at 0 from midnight until 07:01, ruling out nocturnal intrusion.

Window state changed to open (10000%) at 12:21, exactly when bedroom occupancy turned to 1, proving human agency.

Monitor the 'Auto' lock operation at 07:01:10; if it occurs repeatedly after manual locking, review smart lock settings to prevent accidental unlocking.

No immediate security response required.

Evidence confirms a period of unauthorized occupancy in the bedroom (12:32-13:54) and living room (13:54), occurring while the home was officially locked and registered as empty from midnight until 08:37.

Explanation: Raw logs show clear 'Occupancy=1' events in the bedroom at 12:32 and again at 13:54, contradicting the Stage-1 summary's claim of no activity during this window.

Explanation: The sequence shows the resident leaving at 08:37 (manual lock, door contact opening), followed by an unexplained return to the bedroom at 12:32 and subsequent light/window adjustments, indicating someone entered after hours.

Explanation: The front door was manually re-locked at 20:46 immediately after the bedroom window was closed and lights turned on, suggesting the intruder exited or left the house exactly when the system reset its status.

[2026-06-22T12:32:09] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-22T13:54:00] bedroom_occupancy | OccupancySensing.Occupancy = 1

[2026-06-22T13:54:05] living_room_occupancy | OccupancySensing.Occupancy = 1

Verify physical security of the property immediately; check for signs of forced entry at windows and doors.

Review camera footage specifically between 12:30 and 13:55 to identify the intruder.

Change all access credentials (smart locks, phone apps) and consider replacing mechanical keys if applicable.

All rooms show Occupancy=0 starting from 00:00, suggesting the house has been empty since midnight, making the 08:37-20:46 activity highly suspicious if no one is logged as present.

Door locked manually at 08:37 (suggesting departure).

Bedroom window opened (0%) at 13:54 (hours after departure?).

Bedroom window closed (100%) at 20:46 (nighttime).

Front door unlocked automatically (Auto source) at 20:46, coinciding exactly with the window closing event.

Complete lack of occupancy signals throughout the day despite significant device interactions.

Check raw motion sensor logs (occupancy_sensor) specifically for the bedroom timestamp range 13:54 to 20:46 to confirm if anyone entered/occupied the space.

Verify the source of the 'Auto' unlock at 20:46: Was it a scheduled routine, remote access, or triggered by a sensor that isn't showing in the summary?

Cross-reference camera footage (if available) or doorbell logs between 08:30 and 09:00 to confirm the resident's actual exit time.

The front door lock exhibits a sequence of manual override followed by immediate auto-locking with conflicting contact sensor states, suggesting either a malfunctioning smart lock or an attempted intrusion that was aborted.

Explanation: Occupancy logs confirm the home was empty at 05:21 and 07:02, making manual interactions highly suspicious or indicative of automation failure.

Explanation: At 07:02:08, a 'Manual' lock event occurred on an unoccupied property, immediately followed by an 'Auto' unlock/lock cycle.

Explanation: Critical inconsistency detected: The door contact sensor reported 'False' (open) at 07:02:10 but switched back to 'True' (closed) just two seconds later at 07:02:13, without any recorded human presence to account for this rapid transition.

Explanation: While H3 suggests window manipulation, the log shows curtains moving while lights turned on in an empty house, pointing more towards system glitches than coordinated human activity.

Physically inspect the front door lock mechanism for physical damage or signs of tampering.

Verify if the 'Manual' operation source can be attributed to a specific user device or app command via the smart home dashboard history.

Test the door contact sensor alignment and functionality as it is reporting contradictory states.

Check if the Manual lock operation at 07:02:08 was initiated by a specific user ID or smart device command vs. physical tampering attempt.

Verify the state of the bedroom window sensor immediately before and after the curtain position change at 05:21:08 to confirm if the window itself was opened/closed.

Cross-reference the occupancy logs around 05:21 and 07:02 to see if any motion was detected in the bedroom or hallway prior to these events.

Review historical patterns for the resident's typical wake-up time and routine to determine if 05:21 and 07:02 are anomalous timestamps.

The rapid sequence of manual lock, door contact closure (indicating the door was physically opened), and subsequent auto-unlock is consistent with a resident opening their own door to leave or enter briefly, rather than an intrusion.

Explanation: At 07:00:09, the user manually locked the door (LockState=2).

Explanation: At 07:00:11, the door contact sensor registered 'False' (door open), indicating the user physically opened the door shortly after locking it, likely to retrieve something or step outside momentarily.

Explanation: At 07:00:13, the contact returned to 'True' (door closed).

Explanation: At 07:00:14, the system triggered an 'Auto' unlock command. In many smart locks, if a door is opened while armed/locked or immediately upon closing via a specific schedule or motion trigger, the system may automatically disengage the deadbolt for convenience, which explains the state change to Unlocked (1) without external tampering.

Explanation: No unauthorized occupancy events or alarm triggers occurred during this window, and the pattern repeats logically at 20:37 when the user returns.

[2026-06-11T07:00:14] ... LockOperation(LockOperationType=0, OperationSource=Auto)

Review smart lock settings to ensure 'Auto Unlock' does not trigger unexpectedly if the door is opened while the system is in a secure mode.

Verify the physical alignment of the door contact sensor to prevent future false readings if the gap between closing and unlocking becomes too narrow.

High activity count in other rooms (Kitchen, Living Room) before the suspicious 07:00 sequence implies the resident was inside, making a successful breach unlikely without detection unless they left quickly.

No subsequent motion events in the focus list between 07:00 and 08:37 to suggest someone entered while the door was supposedly unlocked by 'Auto'.

Check raw GPIO or motor driver logs for the front_door_lock between 07:00:09 and 07:00:14 to confirm if the 'Auto' unlock command originated from a valid smart-home controller signal or an external/unauthorized source.

Verify if the 'Auto' unlock event triggered any security alarm arming/disarming logic in the system configuration.

Cross-reference with network traffic logs to see if there was an unsolicited connection to the door lock device IP at 07:00:14.

Check if the 'Manual' lock at 08:37:00 successfully engaged the deadbolt mechanically, or if it only engaged the latch.

Kitchen smoke alarm triggered during unoccupied hours with a rapidly rising temperature trend in the kitchen sensor, indicating an active fire or severe overheating event.

Explanation: Smoke alarm (kitchen_smoke_alarm) explicitly triggered at 16:37:00 while occupancy sensors confirmed all rooms were empty (0) for several hours prior and immediately after.

Explanation: Raw temperature logs show a consistent and rapid increase in kitchen temperature starting from ~22°C at midnight to ~248°C by 06:30, suggesting unattended cooking or equipment failure leading to ignition risk.

Explanation: The sequence of events (empty house -> rising temp -> smoke alarm) strongly correlates with an unattended fire hazard rather than normal environmental drift.

Immediately dispatch emergency services/fire department due to active smoke detection.

Send automated alerts to all household members' mobile devices with location context.

Check kitchen cook_surface and temperature_sensor logs between 16:35 and 16:40 to confirm if cooking caused smoke or if it was an external breach.

Verify the specific value mapping of 'WindowCovering.CurrentPositionLiftPercent100ths': does 10000 mean fully open or a fault code? Check motor power consumption logs for the window cover.

Review raw access logs for the front_door_lock to determine if the 'Auto' source corresponds to an automated smartlock feature or a relay triggered by an external signal (e.g., hacking the lock controller).

Cross-reference CCTV footage (if available) with the timestamps 16:37 (smoke) and 21:57 (window/door activity) to visually confirm occupancy status.

Sequential manual unlocking of the front door at 07:38 followed by a brief period where the door was open (contact sensor false) before auto-locking suggests an unauthorized entry or tailgating attempt.

Explanation: The log shows a Manual Lock Operation (Unlock) at 07:38:23, immediately followed by the Door Contact Sensor reporting 'False' (Open) at 07:38:25.

Explanation: The door remained in the open state until 07:38:31, after which it automatically locked again, indicating a person passed through and triggered the auto-lock timer.

Explanation: While morning entries can be authorized, the specific sequence of manual unlock -> immediate physical opening -> delayed auto-lock is a classic signature of tailgating or forced entry without proper authentication logging.

[2026-06-18T07:38:25] front_door_contact | BooleanState.StateValue = False

Review front door camera footage specifically between 07:38:20 and 07:38:40 to identify the individual.

Check keypad/fob logs to verify if the manual unlock corresponded to a valid user credential or an override event.

Temporarily adjust auto-lock timeout settings or require explicit re-authentication for the next cycle if unauthorized access is confirmed.

Raw motion sensor logs for the hallway/entrance area between 07:38:20 and 07:38:40 to detect secondary entries.

Bedroom window motor control logs to determine if the window opening was triggered manually or remotely via an unknown device.

Front door camera footage (if available) or keypad entry logs to verify if the manual unlock was authorized user action or forced entry.

Network traffic logs for smart devices around 21:56:45 to check for unauthorized remote access commands.
