The event sequence represents a normal morning routine where residents left the house, with the door briefly open for passage and sensors correctly reflecting the state changes.

Explanation: Occupancy logs show residents were inside (Bedroom/Bathroom active) until 07:18:05 when lights turned off, immediately preceding the door unlock at 07:18:13.

Explanation: Door contact sensor data confirms the door was only open between 07:18:15 and 07:18:22 (7 seconds), which is consistent with a resident walking through rather than lingering or forced entry.

Explanation: All occupancy sensors returned to '0' during this interval, confirming no one remained inside while the door was ajar, ruling out an intruder waiting inside.

[2026-06-04T07:18:22] front_door_contact | BooleanState.StateValue = True

Acknowledge event as normal household activity; no further action required.

Verify that the short duration of the door being unlocked/unlatched is within acceptable parameters for the specific automation rules if fine-tuning is desired in the future.

Sequence: Manual Unlock -> Auto Lock within 10 seconds (07:18:13 to 07:18:23). This suggests the door was opened briefly without a person lingering or a sensor triggering a delayed close, possibly indicating forced entry or testing.

Bedroom window state change occurred while all room occupancies were zero, followed immediately by the evening return event.

Door contact sensor status readings exactly between 07:18:13 and 07:18:23 to confirm if the door remained fully open or just cracked.

Any motion spikes or vibration alerts on the front door hardware during the 10-second window.

Audio logs or smart speaker interactions around 07:18 to see if there was verbal confirmation of opening/closing.

History of previous 'Auto' lock triggers to determine if this timing pattern is a known automation glitch or a new behavior.

The house was empty overnight due to residents being away; all sensor readings (occupancy and temperature) are consistent with a normal unoccupied state followed by resident return.

Explanation: Occupancy sensors confirmed zero presence in all rooms from 00:00 to 06:33, consistent with the house being unoccupied.

Explanation: Temperature logs show a gradual rise (from ~22°C to ~25°C) typical of indoor heating without active cooling or intrusion, refuting forced entry hypotheses.

Explanation: Resident activity resumed normally at 06:33 (bedroom occupancy detected), lights turned on, and manual door locking occurred at 07:38, indicating legitimate user interaction.

No action required; system is operating normally.

Continuous 0 occupancy readings from 00:00 to 01:30 across all monitored rooms.

Room activity distribution shows low counts for entrance (11) compared to kitchen/living room during active hours, but no late-night activity.

Zero occupancy detected in Living Room, Bedroom, and Bathroom between 00:00 and 01:30, indicating the home is completely unoccupied.

Door lock state changes (LockState = 1/2) occurring during the period of confirmed total vacancy (00:00 - 01:30).

      "supported_by": [


An intruder entered the home at night (00:00-23:06), bypassed security to open a window, and triggered an automated or unauthorized system command to unlock the front door while occupancy sensors confirmed the house was empty.

Explanation: Occupancy sensors consistently reported '0' (empty) for all rooms between midnight and 23:06, confirming no authorized residents were present.

Explanation: At 23:06:16, the bedroom window coverings were opened (100%), indicating forced entry or manipulation from the inside by an intruder who had already gained access.

Explanation: Exactly 10 seconds later, the front door lock changed state to unlocked (LockState=1) with source 'Auto', suggesting a compromised automation routine or malicious trigger activated upon the window opening event, effectively locking out any potential escape route or signaling the breach.

[2026-06-14T23:06:07] bedroom_occupancy | OccupancySensing.Occupancy = 1 (Previous state implies presence earlier, but immediately after at 23:06:07 it flips to 1? Wait, log shows 23:06:07 is 1. Let's re-read carefully. Ah, the log snippet shows 23:06:07 as Occupancy=1. This contradicts the 'empty' hypothesis slightly if interpreted as current resident. However, looking at the sequence: 23:06:16 Window opens -> 23:06:25 Door Contact Open -> 23:06:26 Lock Unlocked. The critical factor is the *sequence*. If Occupancy was 1 at 23:06:07, did someone leave? Or is this a ghost sensor? No, let's look at the context of H1 vs H2. H1 says 'all rooms confirmed empty'. The log provided in Stage 1 supports 'empty' at 00:00. The raw log shows Occupancy=1 at 23:06:07. This is the anomaly point. An occupant detected, then immediately at 23:06:16 the window opens (while still occupied?), then door unlocks. OR, more likely, the 'Occupancy=1' at 23:06:07 is a false positive or the person left just before the camera/sensor triggered the window event. BUT, the most telling evidence is the **automated unlock** (Source=Auto) occurring 9 seconds after the window was fully raised. Legitimate users do not automate unlocking doors based on window status during night hours. Combined with the prior long period of '0' occupancy (00:00 to 23:06:07), it implies the resident left, the house sat empty for 23 hours, then an intruder entered, opened the window, and triggered the auto-unlock.

The specific event sequence: Window Covering lift to 100% (23:06:16) followed immediately by Front Door Lock operation (Type=0, Source=Auto) at 23:06:26, creating a direct causal link between an unauthorized window opening and the deactivation of the primary perimeter defense.

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

Secure the premises and change all smart home credentials (usernames/passwords) associated with the lock and automation logic.

Review network logs for IP addresses connecting around 23:06 to identify potential remote attackers or compromised devices.

The sequence of events represents a normal evening routine where the resident opened the window cover and unlocked the door to enter the home.

Explanation: Occupancy sensors confirmed the home was empty from midnight until 06:33 (morning departure), establishing a baseline of no unauthorized presence overnight.

Explanation: At 22:08:30, the bedroom window covering moved to fully open (10000), which is consistent with a resident preparing to enter rather than an intruder forcing entry (intruders typically do not raise shades before breaking in).

Explanation: Exactly 10 seconds later at 22:08:40, the front door lock automatically unlocked immediately after the door contact sensor registered opening, confirming the resident entered through the main door following their own actions.

bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 at 22:08:30

front_door_contact | BooleanState.StateValue = True followed by LockOperation(LockOperationType=0) at 22:08:40

Wait, re-evaluating: The sensor log shows WindowCovering.CurrentPosition. It does NOT show the ContactSensor state for the bedroom window. If the window cover is open, the contact sensor should ideally reflect if the window glass is open/closed. The absence of a specific 'Window Open' contact event in the suspicious signals, combined with the high count of focus events (108) vs salient (60), suggests many minor noise events exist but no major alarm triggered.

The window cover opening at 22:08:30 immediately precedes the manual unlock at 22:08:40. This temporal correlation strongly implies the resident preparing to enter, not an intruder forcing the window.

No smoke, leak, or fire alarms are present in the suspicious signals.

Temporal alignment of Bedroom Window Cover opening (22:08:30) and Front Door Manual Unlock (22:08:40)

Absence of explicit 'Contact Sensor Open' events for the bedroom window in the provided snippet despite the cover being raised

Check the raw contact_sensor logs for 'bedroom_window' specifically between 22:08:00 and 22:10:00 to confirm if the window glass itself was opened or remained closed.

Verify the source IP/MAC address of the front_door_lock operation at 22:08:40 to confirm it matches the homeowner's mobile device.

Review motion sensor logs for the hallway/entrance area around 22:08 to see if movement preceded the door unlock.

The sequence of events (window closing, door contact triggered, auto-lock) is a consistent and logical automated 'Away' routine confirmed by the subsequent activation of morning schedules.

Explanation: Occupancy sensors registered presence in the bedroom at 23:05:08 immediately preceding the window closure at 23:05:17, ruling out an empty-house scenario.

Explanation: The system followed a strict temporal logic: Occupancy detected -> Window closed -> Door contact triggered -> Auto-lock engaged, indicating a standard automation chain rather than random intrusion or hijacking.

Explanation: The entire event cycle concludes with the activation of morning routines (lights on, AC mode change) starting at 08:34, confirming the system entered a scheduled 'Away/Goodnight' state that was successfully resolved upon user return the next day.

Evidence indicates an intruder entered the home via the front door (triggering auto-lock) after opening the bedroom window at 23:03, while the house was unoccupied.

Explanation: Occupancy sensors confirmed all rooms were empty from 00:00 onwards until 23:03:14, when the bedroom occupancy suddenly changed to 1 without any prior motion detection or entry event in other areas.

Explanation: The sequence shows the bedroom window opening immediately followed by the front door contact sensor triggering (True) and the lock engaging automatically, which contradicts normal exit behavior where windows are closed before leaving.

Explanation: The absence of a user-initiated command for the window opening combined with the sudden appearance of occupancy suggests manual tampering rather than an automated routine.

[2026-06-20T23:03:25] front_door_lock | Event: LockOperation(... OperationSource=Auto)

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

Dispatch security personnel to inspect the front door and bedroom window for signs of forced entry.

Review video surveillance footage if available to identify the suspect.

Simultaneous timestamp proximity between Bedroom Window Opening (23:03:16) and Front Door Locking (23:03:25).

Abnormally high total event count (1343) compared to salient/focus events, indicating potential logging anomalies or rapid device triggering.

Sequence: Window Open -> Door Lock. This contradicts standard egress behavior where doors are locked *after* windows are secured, or implies an intruder opened a window then triggered the lock (if the lock logic is sensitive to magnetic field changes caused by opening).

Check the raw state of the front_door_contact_sensor (contact_sensor) around 23:03: Did the door actually open/close physically, or did the lock motor engage without physical movement?

Verify the command source for the bedroom_window covering operation at 23:03: Was it a mobile app command, a voice assistant, or an automated rule trigger?

Analyze the log stream between 23:03:16 and 23:03:25 for any preceding motion detection in the living room or hallway that might explain the sequence.

Check if the 'Auto' lock operation was triggered by a geofence exit event (user phone leaving) or a proximity sensor, given the window state change happened seconds prior.

High confidence evidence of a forced entry attempt or break-in at the front door during a time when the house was empty.

Explanation: The home was confirmed empty for over 10 hours prior to the incident (occupancy sensors showed 0 from 00:00 to 06:26), and no occupants were present in the living room at the time of the event (07:38).

Explanation: At 07:38:13, a manual unlock occurred while the lock state was 'Unlocked' (2), followed immediately by the door contact sensor going 'False' (open) at 07:38:15. This indicates the door was physically opened after being unlocked.

Explanation: The door contact sensor returned to 'True' (closed) at 07:38:23, and the system automatically locked the door ('Auto') at 07:38:24. The rapid sequence of Manual Unlock -> Physical Opening -> Auto Lock within 11 seconds is characteristic of a breach where an intruder entered and triggered an automated safety response upon closing, rather than standard user behavior.

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

Do not enter the property until police have cleared it.

Change locks on the front door once authorities confirm the scene is safe.

Total room activity counts are low relative to event count (e.g., kitchen: 20, living_room: 34)

Rapid transition from Manual Unlock to Auto Lock on the front door within 11 seconds (07:38:13 to 07:38:24).

Front door lock state changed from Unlocked (2) to Locked (1) automatically shortly after a manual interaction.

Complete lack of occupancy sensor readings (>0) in all rooms during the morning and early afternoon hours.

Raw motion sensor logs between 07:38:00 and 07:40:00 to determine if any movement was detected inside the home prior to the auto-lock.

Door contact sensor logs to verify if the door was physically opened more than a threshold duration or force during the 07:38 window.

Smartphone/user app connection logs to see if the 'Auto' lock command originated from a remote device (e.g., user phone) or a local automation rule.

Temperature logs in the kitchen and living room between 06:00 and 18:00 to confirm absence of human presence (e.g., cooking spikes, AC usage).

Evidence indicates a high-confidence unauthorized entry and exit sequence where an intruder manually locked the door from the outside while the house was empty, followed by an automatic sensor-triggered unlock.

Explanation: Occupancy logs confirm the home was completely empty (all rooms = 0) during both suspicious events at 07:13 and 18:24.

Explanation: At 07:13:21, a 'Manual' lock operation occurred immediately followed by the door contact sensor detecting the door closing (State False) and then opening (State True), consistent with someone locking it shut from the exterior before walking away.

Explanation: The subsequent 'Auto' unlock event at 07:13:24 (3 seconds after manual lock) is characteristic of a smart lock's geofence or motion-activated routine releasing the bolt once the system believes the user has exited, inadvertently leaving the door unlocked for the intruder who had already gained access.

[2026-06-03T07:13:23] front_door_contact | BooleanState.StateValue = False (Door closed)

Immediately change the credentials (PIN/keys) for the front door lock and all linked accounts.

Contact local law enforcement to file a report regarding potential break-in attempts.

Review camera footage from the porch/entryway if available to identify the intruder.

The specific combination of 'Manual' source triggering a lock that instantly reverts to 'Auto' unlock logic is highly irregular for standard maintenance.

Check raw Bluetooth/Wi-Fi handshake logs for the front_door_lock device at 07:13:21 to identify if a physical key card/fob access or proximity trigger occurred from inside vs outside.

Verify if the 'Auto' unlock at 07:13:24 was triggered by a geofence exit event (user phone leaving) or a timer-based routine.

Cross-reference mobile app usage logs to see if the homeowner manually initiated any lock/unlock commands around these timestamps.

The house was unoccupied overnight until a front door contact opened and the lock disengaged automatically while no occupancy sensors detected anyone inside.

Explanation: Occupancy logs show all rooms (living room, bedroom, bathroom) were empty (0) continuously from 00:00:00 to 23:12:09.

Explanation: At 23:12:19, the front door contact sensor triggered an open state (BooleanState = True), indicating the door was physically opened.

Explanation: Immediately following the door opening at 23:12:20, the lock operation source is 'Auto' with LockState=1 (unlocked/opened), which contradicts standard security protocols where doors should remain locked or require manual unlocking if occupied; combined with zero occupancy, this indicates an unauthorized entry event bypassing normal routines.

Explanation: No subsequent occupancy detection occurred in any room after the door event within the log window, suggesting the intruder may have entered but failed to trigger motion sensors or left immediately.

[2026-06-13T23:12:19] front_door_contact | BooleanState.StateValue = True

Continuous OccupancySensing.Occupancy = 0 for all rooms from 00:00:00 to 23:12:09

Dispatch security personnel to verify property status immediately.

Check surveillance footage if available for the time range 23:12:00 - 23:30.

Reset smart lock to default secure state and review access logs.

If the house was truly unoccupied since 00:00:00 (as per occupancy logs), an 'Auto' unlock at 23:12:20 implies either the system woke up, a sensor failed, or it was indeed an intrusion that bypassed standard security protocols. The timing (late night) combined with zero occupancy makes a purely routine 'goodnight' sequence unlikely if the doors were supposed to remain locked throughout the night.

No activity logs suggest anyone entered the premises after 23:12:20.

Sequence of OccupancySensing.Occupancy = 0 across all rooms starting from 00:00:00

Check raw logs for any motion sensor triggers in the entrance hallway between 23:12:00 and 23:15:00.

Verify the definition of 'LockOperationType=0' and confirm if 'Auto' corresponds to a scheduled schedule or an automated response to a specific trigger (e.g., opening the door).

The event represents a normal resident leaving the house early in the morning (07:23) after waking up, evidenced by the sequence of occupancy changes and lighting control.

Explanation: Occupancy sensors remained at 0 until 06:19, when the bedroom light turned on, confirming the resident woke up naturally rather than being undetected for hours.

Explanation: At 07:23, the manual unlock coincided exactly with the bedroom light turning off, indicating the resident prepared to leave.

Explanation: The door contact sensor confirmed the door opened (State=False) and closed (State=True) within 8 seconds, followed immediately by an automatic lock, which is standard behavior for a resident exiting.

[2026-06-25T07:23:28] front_door_contact | BooleanState.StateValue = True

No action required; this is consistent with normal daily routine.

Continue monitoring for any future deviations from established patterns.

Tailgating or forced entry attempt: The 'Auto' source for the 07:29 lock might indicate a sensor-triggered close (e.g., door slammed shut by an intruder trying to break in, or a malfunction), rather than the resident walking through.

LockOperationType=0 (Auto) shortly after manual interaction could imply mechanical force or rapid movement rather than gentle human closure if no occupant was detected inside.

Standard smart locks often use 'Auto' to denote the battery-powered latch engaging, not necessarily an external force event, without additional vibration/impact data.

[2026-06-25T00:00:00] living_room_occupancy | OccupancySensing.Occupancy = 0

[2026-06-25T00:00:00] bedroom_occupancy | OccupancySensing.Occupancy = 0

Check motion detection confidence scores around 07:23 to see if any micro-movements were detected before the manual unlock.

Verify the timestamp precision difference between the manual unlock and the subsequent 'Auto' lock; a significant gap (>5s) suggests the person walked away, while immediate engagement suggests standing still or forcing the door.

Cross-reference energy usage logs (AC, lights) between 07:23 and 08:00 to confirm if systems turned off (supporting vacancy) or remained active.

Check camera footage (if available) or audio logs for sounds of struggle or multiple people entering/exiting.

Total absence of occupancy signals in Living Room, Bedroom, and Bathroom for over 22 hours post-midnight.

Check the raw binary/log stream for the front_door_lock around 22:05:41 to confirm if the 'Auto' source corresponds to an external sensor trigger (e.g., motion detected outside) rather than a legitimate smart-home automation rule.

Verify if there are any contact_sensor events on the bedroom_window indicating it was physically opened before the curtains were commanded to open.

Cross-reference with outdoor temperature/motion sensors or security camera feeds if available to see what triggered the door unlock.

Confirm the timestamp accuracy of the occupancy sensors to ensure they did not miss detecting someone entering after midnight.

The event sequence represents normal household occupancy and door locking/unlocking cycles with no signs of intrusion or malfunction.

Explanation: Occupancy sensors show a clear pattern: empty house (0) during late-night hours (00:00-07:10) and populated state (1) only upon entry at 07:10 and 18:05.

Explanation: The 07:10 AM cycle shows a complete Lock -> Contact Open -> Auto Unlock sequence, consistent with a resident leaving home.

Explanation: The 18:06 PM cycle mirrors the morning pattern: Occupancy detected at 18:05, Manual Lock at 18:06, followed by the door contact opening at 22:10 and an Auto Unlock occurring shortly after, confirming a standard exit routine without forced entry or unauthorized re-entry.

Explanation: No alarm signals, tamper alerts, or conflicting sensor data (e.g., locked while occupied inside) were detected.

[2026-06-04T22:10:54] front_door_lock | DoorLock.LockState = 1

Check the raw log entries immediately following the 18:06:00 LockEvent to see if there was an attempted unlock, a sensor trigger indicating forced entry, or if the system remained locked until morning.

Verify the source IP address or device ID associated with any 'Auto' unlock operations to ensure they originate from the legitimate smart-home hub/app and not a spoofed signal.

Cross-reference the 18:06:00 lock time with the occupancy sensor data for the 'entrance' and 'living_room' to confirm if anyone actually exited the premises or if the lock was triggered while the door was closed inside.

No security threat detected; log data confirms consistent occupant presence and normal daily lock/unlock routines.

Explanation: Occupancy sensors show '0' (empty) throughout the night (00:00-06:59), consistent with residents being asleep or away.

Explanation: At 07:52:00, a master_bedroom_occupancy event ('1') occurs immediately after the morning door interaction, confirming the resident was inside before the first manual lock.

Explanation: The sequence at 07:50 shows the door opening (contact False->True) between the manual lock attempt and the auto-unlock, indicating the user exited and re-entered normally rather than an unauthorized entry.

Explanation: Evening events (window closing, lights off) followed by auto-locking align perfectly with a standard bedtime routine.

The event is a routine security protocol where the system automatically re-locks the front door immediately after it was manually opened (tailgating prevention) during a time of confirmed house vacancy.

Explanation: Raw logs show a sequence at 07:16 and 18:07 where Occupancy=1 triggered Manual Locking (State 2), followed immediately by Auto-Unlocking (State 1) upon Contact=False (door closed). This establishes a standard 'open then auto-relock' pattern.

Explanation: At 22:09, the log shows front_door_contact=True followed instantly by LockOperationType=0 (Unlock) and State=1. Crucially, this occurs while all internal occupancy sensors have reported '0' for hours, indicating the user left long before this event.

Explanation: This behavior contradicts an intrusion hypothesis because an intruder would typically need to enter (Occupancy=1 or contact state change logic) or bypass the lock; here, the sensor confirms the house is empty, and the action is an automated safety mechanism ensuring the door isn't left ajar if someone accidentally held it open or if the contact sensor registered a transient closure.

Explanation: The pattern mirrors the earlier morning/evening events (e.g., 07:16 sequence) but adapted for nighttime automation rules, serving as a fail-safe rather than a breach.

[2026-06-05T22:09:32] front_door_contact | BooleanState.StateValue = True

All room occupancy sensors report '0' continuously from 00:00 until 07:16 when residents return.

Verify smart-home automation settings to ensure 'Auto-ReLock on Door Close' is active as intended.

Review firmware definitions to confirm LockState=1 consistently means 'Unlocked' and not 'Securely Locked' in edge cases, though current context strongly implies standard unlock.

[2026-06-05T18:07:00] front_door_lock | DoorLock.LockState = 2

Verify the definition of LockOperationType=0 and LockState=1 in the device firmware (ensure State=1 does not mean 'Securely Locked' contrary to standard conventions where 2 often means locked).

Review smart-home automation rules to see if a scheduled 'Goodnight' routine includes an intentional unlock command that might be misinterpreted as suspicious.

Cross-reference the 'entrance_occupancy' sensor specifically right before the unlock event to confirm no one was standing directly at the door triggering a false negative or bypass.

Multiple instances of manual front door unlocking occurred while the house was confirmed unoccupied by all internal sensors, suggesting unauthorized entry or attempted tailgating.

Explanation: The raw logs confirm the house was empty (all occupancy sensors = 0) at 07:40, yet a manual lock unlock event occurred, followed immediately by an auto-lock and a contact sensor transition indicating the door closed without a resident triggering motion inside.

Explanation: A second suspicious event occurred at 16:22 where the entrance sensor triggered to '1' just before a manual unlock, but the master bedroom occupancy remained '1', creating a discrepancy between the entry trigger and the lack of subsequent interior activity for that specific loop, whereas the 07:40 event had zero prior occupancy.

Explanation: The sequence of manual unlocks at 07:40, 16:22, and 18:01 represents a pattern of interaction with the primary entry point in the absence of verified occupant presence, consistent with forced entry attempts, testing locks, or unauthorized access.

[2026-06-25T16:22:00] front_door_lock | DoorLock.LockState = 2

The sequence of manual unlocks without immediate motion detection implies either the person didn't enter, or the sensor failed, or they entered via a window (master_bedroom window fully open).

Burglary via window access: Master bedroom window is reported as 100% open (fully up/lifted) at 22:36, shortly before an automatic lock disengage event, suggesting potential bypass of the main door.

[2026-06-25T22:36:14] master_bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000

Note: LockState changes to 1 (unlocked) at 22:36:17.

        "If residents were present to trigger the high room activity counts (especially kitchen and entrance), we would expect occupancy sensors to be active during the times of manual door operations (e.g., 07:40, 16:22, 18:01). The absence of specific timestamped occupancy transitions for these events makes this less likely to be standard daily routine if the house is empty.",
        "The sequence of manual unlocks without immediate motion detection impli


The event sequence represents a normal evening departure routine where residents left the house, locked the door manually upon exit, and the system subsequently auto-locked it after confirming vacancy.

Explanation: Occupancy sensors confirmed all rooms were empty starting at 00:00:00, establishing prolonged vacancy consistent with an overnight absence.

Explanation: At 22:46:13, occupancy was detected in the master bedroom, indicating the last resident was still inside before leaving.

Explanation: The lock operation at 22:46:25 was explicitly 'Auto' triggered immediately after the front door contact sensor transitioned to 'True' (closed), which is standard behavior for smart locks engaging security once the door is shut and no one is inside.

Explanation: The previous manual lock event at 07:36:18 resulted in LockState=2 (likely unlatched/ajar or specific device state) followed by an Auto-lock to State=1, proving the system's auto-lock logic functions correctly and was likely responsible for the 22:46 action as well.

Continue monitoring; no immediate action required.

Verify that the 'LockState' values (1 vs 2) align with the specific brand's definition of 'Secured' vs 'Unsecured' in the user manual to ensure future clarity.
