FG-02-FP: 电暖器/取暖器正常使用

有人在房间且温度上升后趋于稳定（不是持续飙升），无烟雾报警触发

moderate - Identifies specific null value events which are technically anomalies in data streams.

strong - Provides corroborating evidence from other sensors showing consistent thermal trends, proving the device was functional and the nulls were transient transmission issues rather than hardware failure.

The defense successfully refuted the claim of 'malfunction' by demonstrating that the sensor's readings before and after the null events aligned perfectly with the home's overall cooling trend. This indicates the sensor was working correctly and the nulls were likely due to network congestion or sleep cycles (normal IoT behavior), not a fault requiring maintenance.

No security threat detected; observed data gaps are explained as normal transient communication drops in a functioning sensor network.

Monitor for recurrence if frequency increases significantly.

2026-06-01T19:35:00 | kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None

Explanation: The kitchen temperature sensor exhibits intermittent total data loss (null values) during a period of high activity and normal temperature ranges. While other sensors in the home reported stable temperatures (22-27°C), the kitchen sensor's inability to transmit data compromises the integrity of environmental monitoring in a high-risk area (cooking). This pattern is consistent with a hardware or connectivity malfunction.

2026-06-01T18:15:00 | kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 25.75 C (raw=2575)

2026-06-01T19:15:00 | kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 24.12 C (raw=2412)

The kitchen temperature sensor has experienced two distinct instances of complete data transmission failure (null values) within a short timeframe, indicating a functional malfunction. Although no immediate physical danger like fire was detected, the loss of telemetry from a critical safety zone undermines the reliability of the home's environmental monitoring system. This constitutes a device fault that requires maintenance to ensure future safety coverage.

The kitchen temperature sensor experienced two distinct instances of complete data transmission failure (null values) within a short timeframe, indicating a functional malfunction.

The 'null' values are likely transient communication drops or scheduled maintenance cycles common in Matter/Thread networks, rather than hardware failure. The sensor resumes normal operation immediately after these events (e.g., reporting 23.59°C at 19:20 and 22.62°C at 20:15), showing no persistent fault. A true malfunction would typically result in stuck values or total silence for longer periods, not intermittent nulls followed by immediate recovery.

2026-06-01T20:10:00 | kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 22.69 C (raw=2269)

This pattern is consistent with a hardware or connectivity malfunction compromising the integrity of environmental monitoring.

The overall system integrity remains high. Other sensors in the same environment (Living Room, Master Bedroom) show stable, correlated temperature trends (dropping from ~25°C to ~22°C as evening progresses). The kitchen sensor's readings before and after the null events align perfectly with this thermal decay curve, suggesting the sensor was functioning correctly and simply missed specific polling intervals due to network congestion or power-saving sleep states, which is normal behavior for battery-operated or low-power IoT devices.

living_room_temp_sensor: start=22.78C, end=22.68C, max=25.59C

kitchen_temp_sensor: start=22.67C, end=22.63C, max=27.14C

Temperature Trends show consistent cooling across all rooms from afternoon to night.

The home is operating normally with occupants present in the living room and entrance areas during the evening. The kitchen temperature sensor experienced minor, transient telemetry gaps (null values) but recovered immediately, with subsequent readings consistent with the home's overall cooling trend. No evidence of hardware failure or security breach exists; the system is functioning within expected parameters for smart-home connectivity.

The kitchen sensor did report 'None' twice, indicating brief moments where data was not successfully transmitted or parsed.

## Matter Notes
- These logs follow Matter-style smart-home event semantics.
- TemperatureMeasurement.MeasuredValue is represented in centi-degrees Celsius in this benchmark: 2466 means 24.66 C, not 2466 C.
- BooleanState and other protocol booleans should be interpreted using transitions and surrounding events, not naive natural-language assumptions from a single isolated value.
- OccupancySensing.Occupancy uses 0=unoccupied and 1=occupied.
- DoorLock.LockState is an enumerated state; formatted logs may show both the label and the raw code.
- A device-fault conclusion requires direct fault evidence such as stuck values, repeated non-recovery, explicit alarm/fault events, or impossible state transitions. Scaled temperature values alone are not enough.

weak - relies on misinterpretation of telemetry protocols ('None' as failure) and weak correlation between unrelated events.

strong - provides protocol-specific explanation for 'None' values (change-based reporting), supports with evidence of immediate recovery, and contextualizes temperature readings with appliance usage.

The Defender successfully refuted the core premise that 'MeasuredValue=None' indicates a hardware malfunction by explaining it as a standard behavior in Matter-style change-based reporting. The logs showed normal operation resuming immediately, contradicting the claim of persistent failure or drift.

No anomaly detected; reported sensor gaps are consistent with normal change-based reporting protocols and do not indicate device failure or safety risks.

Continue monitoring sensor health via automated uptime checks.

Verify that change-threshold settings for the temperature sensor are appropriate for the environment.

Significant temperature spike compared to surrounding readings (~25.1 C) and other sensors, potentially indicating a sensor drift or environmental anomaly that coincides with later communication failures.

Explanation: The kitchen temperature sensor exhibits intermittent total data loss (null values) during active hours (evening), which compromises the integrity of the home's environmental monitoring. While no direct fire or intrusion is confirmed, the malfunction of a safety-critical sensor in the kitchen (near cooktop and smoke alarm) creates a blind spot for potential hazards.

2026-06-01T19:16:00 | kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None

2026-06-01T19:44:00 | kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None

2026-06-01T19:43:00 | kitchen/kitchen_cook_surface | OnOff.OnOff=off

The kitchen temperature sensor has suffered a confirmed malfunction, evidenced by two distinct instances of null measurement values at 19:16 and 19:44 on June 1st. This failure renders the device unable to provide critical environmental data during evening hours when cooking activities are likely, creating a gap in safety monitoring capabilities despite the presence of a separate smoke/CO alarm.

The kitchen temperature sensor suffered a confirmed malfunction, evidenced by two distinct instances of null measurement values at 19:16 and 19:44 on June 1st.

The Prosecutor incorrectly interprets 'MeasuredValue=None' as a device failure. In Matter-style telemetry, this typically indicates that the specific attribute report was not triggered or the value was unchanged since the last valid report, rather than a hardware fault. Crucially, the sensor resumes reporting normal values immediately after these timestamps (e.g., 22.57 C at 22:20 in Chunk C13), demonstrating full recovery without any intervention. A true malfunction would likely result in persistent data loss or error codes, not transient gaps followed by immediate return to normal operation.

[2026-06-01T19:44:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None

[2026-06-01T22:20:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 22.57 C (raw=2257)

A significant temperature spike to 27.50 C at 07:15 indicates sensor drift or environmental anomaly coinciding with later communication failures.

The value 27.50 C is consistent with the raw integer 2750 provided in the logs, which translates to 27.50°C. This is a plausible indoor temperature for a kitchen in the morning, especially if cooking activities (cook_surface turned on at 06:45) are occurring. It does not represent an impossible physical state (like 2750°C) nor does it correlate with the later 'null' events, which occurred hours later in the evening. The Prosecutor's claim of 'drift' is unsupported by evidence of calibration errors or out-of-range physical readings.

[2026-06-01T07:15:00] kitchen_temp_sensor | MeasuredValue = 2750

[2026-06-01T06:45:00] kitchen/kitchen_cook_surface | .OnOff=True

The malfunction creates a blind spot for potential hazards in the kitchen.

While the temperature sensor had transient reporting gaps, the kitchen is equipped with a dedicated smoke/CO alarm (smoke_co_alarm). Safety monitoring for fire/gas hazards is primarily handled by this specialized device, not the general-purpose temperature sensor. Therefore, the temporary lack of temperature data does not constitute a critical safety blind spot for life-threatening hazards.

No smoke_co_alarm alerts were triggered during the reported period.

The home environment remained stable throughout the day with no evidence of intrusion or equipment failure. The kitchen temperature sensor experienced standard intermittent reporting gaps (likely due to change-based reporting protocols where values didn't shift enough to trigger a new packet), but resumed normal function immediately. The presence of a dedicated smoke/CO alarm ensures that critical safety monitoring was never compromised, despite the minor telemetry irregularities in the temperature sensor.

The kitchen temperature sensor did report 'None' twice, indicating a brief interruption in data transmission or reporting logic.

## Matter Notes
- These logs follow Matter-style smart-home event semantics.
- TemperatureMeasurement.MeasuredValue is represented in centi-degrees Celsius in this benchmark: 2466 means 24.66 C, not 2466 C.
- BooleanState and other protocol booleans should be interpreted using transitions and surrounding events, not naive natural-language assumptions from a single isolated value.
- OccupancySensing.Occupancy uses 0=unoccupied and 1=occupied.
- DoorLock.LockState is an enumerated state; formatted logs may show both the label and the raw code.
- A device-fault conclusion requires direct fault evidence such as stuck values, repeated non-recovery, explicit alarm/fault events, or impossible state transitions. Scaled temperature values alone are not enough.

weak - relies on interpreting transient network gaps ('None' values) and normal environmental fluctuations (cooking heat) as evidence of hardware failure or safety hazards without corroborating alarm events.

strong - provides direct log evidence showing the sensor resumed normal operation immediately after the 'None' values, attributes the temperature spike to normal cooking activity supported by AC usage logs, and correctly identifies the lack of fire/CO alarms as refuting the catastrophic failure hypothesis.

The Defender successfully demonstrated that the 'malfunction' was a transient communication issue followed by immediate recovery, and the 'anomaly' in temperature was explained by normal household activities. The Prosecutor's claim of permanent failure is contradicted by the subsequent successful readings.

No anomaly detected; observed data gaps and temperature spikes are consistent with normal network behavior and kitchen activity.

Monitor for recurrence of 'None' values to check for persistent connectivity issues.

No immediate safety intervention required.

Recurrent data loss event, suggesting a persistent fault rather than a transient glitch.

TemperatureMeasurement.MeasuredValue = 26.97 C (raw=2697)

Significant thermal anomaly relative to other rooms (e.g., Living Room 23.16C) occurring just before the failure window, potentially indicating a heating element malfunction or sensor drift prior to total failure.

Explanation: The kitchen temperature sensor exhibits a pattern of instability followed by complete communication failure. The spike to 26.97°C at 18:25 is an outlier compared to the stable ~22-23°C in all other occupied zones, which may have triggered the subsequent 'None' values if the device entered a protective error state or lost connectivity due to electrical noise/overheating.

2026-06-22T19:00:00 kitchen_temp_sensor | None

2026-06-22T19:49:00 kitchen_temp_sensor | None

Explanation: While the smoke alarm did not trigger, the combination of a high temperature reading and subsequent sensor failure in the kitchen raises the risk that a fire or electrical fault caused the sensor to fail silently, compromising the safety monitoring capability for that zone.

kitchen/smoke_co_alarm status not explicitly faulted but no alarm events logged

kitchen/cook_surface activity not detailed in snippets but contextually relevant

The kitchen temperature sensor has suffered a confirmed malfunction, evidenced by two explicit 'None' value reports at 19:00 and 19:49. This failure is preceded by a significant thermal anomaly (26.97°C) at 18:25, distinguishing it from normal operation. This constitutes a safety device failure as the primary environmental monitor for the kitchen is non-functional during evening hours when cooking activities are likely.

The kitchen temperature sensor suffered a confirmed malfunction, evidenced by two explicit 'None' value reports at 19:00 and 19:49.

While the logs show 'None' values, this is a common transient state in Matter/Thread networks due to temporary radio interference, device sleep cycles, or network re-association. It does not constitute a permanent hardware failure without further evidence of non-recovery. The sensor resumes reporting normal values immediately after these timestamps (e.g., 23.71°C at 19:20), indicating the device remained functional and connected.

2026-06-22T19:20:00 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 23.71 C (raw=2371)

2026-06-22T19:25:00 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 23.29 C (raw=2329)

A significant thermal anomaly (26.97°C) at 18:25 distinguishes it from normal operation and may indicate a heating element malfunction or sensor drift prior to total failure.

The reading of 26.97°C is consistent with normal kitchen activity during evening hours (cooking/dinner prep). Kitchens naturally run hotter than living areas due to appliance usage. The subsequent drop to ~23°C aligns with the AC running in the living room and general heat dissipation. There is no evidence of 'drift'; the values return to the baseline range observed throughout the day (22-23°C).

2026-06-22T18:21:18 living_room_ac | OnOff.OnOff = on (raw=True)

2026-06-22T18:21:18 living_room_ac | Thermostat.SystemMode = 3

Temperature Trends showing Kitchen max=27.17C and min=22.43C, typical for a kitchen environment.

The combination of high temperature and subsequent sensor failure raises the risk that a fire or electrical fault caused the sensor to fail silently.

This is an unsupported logical leap. The Smoke/CO alarm did not trigger, and there are no other indicators of fire (e.g., sudden occupancy spikes, panic events, or other sensor faults). The 'failure' was brief and self-resolving. Attributing a silent catastrophic failure to a momentary data gap is speculative and contradicts the evidence of normal post-failure operation.

No smoke_co_alarm events logged in Key Events or Focus Chunks.

Kitchen temperature returns to stable 22-23°C range within 20 minutes.

The household experienced normal evening activities, including cooking in the kitchen which caused a temporary temperature rise to ~27°C. The living room AC was activated around 18:21, contributing to the cooling trend seen in subsequent readings. The kitchen sensor briefly reported 'None' values likely due to transient network latency or polling gaps, but resumed normal operation immediately after, showing no signs of permanent damage or hazardous conditions.

The kitchen temperature sensor did report 'None' values at 19:00 and 19:49, confirming a brief communication interruption or data gap.

## Matter Notes
- These logs follow Matter-style smart-home event semantics.
- TemperatureMeasurement.MeasuredValue is represented in centi-degrees Celsius in this benchmark: 2466 means 24.66 C, not 2466 C.
- BooleanState and other protocol booleans should be interpreted using transitions and surrounding events, not naive natural-language assumptions from a single isolated value.
- OccupancySensing.Occupancy uses 0=unoccupied and 1=occupied.
- DoorLock.LockState is an enumerated state; formatted logs may show both the label and the raw code.
- A device-fault conclusion requires direct fault evidence such as stuck values, repeated non-recovery, explicit alarm/fault events, or impossible state transitions. Scaled temperature values alone are not enough.

CH-01-FP: 孩子生病请假在家（家长陪护）

家长也在家（多个房间有活动），不只是儿童房，说明有成人陪护

moderate - The prosecution correctly identifies data gaps ('None' values) but relies on the assumption that these gaps represent a fault rather than normal operational behavior.

strong - The defense provides a technically sound explanation for 'None' values in low-power IoT devices (sleep cycles/polling intervals), supported by the high success rate of valid readings and the absence of explicit error codes or connectivity timeouts.

The defense successfully refutes the claim of malfunction by demonstrating that the observed pattern is consistent with standard low-power IoT device behavior (intermittent reporting due to sleep states). The lack of persistent failure, error logs, or system-wide impact supports the 'normal_explained' verdict over 'anomaly_detected'.

No security threat detected; the sensor's intermittent 'None' readings are attributed to normal low-power sleep cycles.

Monitor the kitchen sensor for any increase in 'None' frequency or duration.

Verify battery levels if the device is battery-powered, as low power can sometimes exacerbate wake-up latency.

Recurrent failure within one minute, suggesting a persistent communication or hardware fault rather than a transient glitch.

Second distinct period of total data loss later in the day.

Continued intermittent failure during evening hours.

Explanation: The kitchen temperature sensor exhibits a pattern of intermittent 'None' values (data dropouts) at specific times (morning and evening), while other sensors in the same environment (living room, master bedroom, kids room) report consistent, physically plausible temperature readings. This isolation of the fault to a single device indicates a local malfunction (connectivity or hardware) rather than a system-wide network issue.

living_room_temp_sensor reports continuous valid data with normal variance (22.42C - 25.59C)

master_bedroom_temp_sensor reports continuous valid data

kitchen_temp_sensor has 4 explicit 'None' events amidst 288 samples

Explanation: While the 'net_change' for the kitchen sensor is listed as -16.00C in the summary, the raw min/max values (22.42C to 25.57C) show a normal daily span of ~3.15C. The large net change likely results from the missing 'None' values disrupting the start/end calculation or a single outlier not reflected in the min/max range provided. However, the direct evidence of 'None' values is sufficient to prove malfunction without relying on this ambiguous metric.

The kitchen temperature sensor is experiencing intermittent hardware or connectivity failures, evidenced by four discrete timestamps where the measured value is explicitly reported as 'None'. This malfunction isolates the kitchen sensor from the rest of the home's stable telemetry, confirming a device-specific fault. While currently low severity due to the presence of redundant environmental monitoring in other rooms, the failure compromises the integrity of any automation or alerts dependent on kitchen temperature data.

The presence of 'None' values in telemetry logs for a battery-powered or low-power IoT sensor (like a temperature monitor) is a standard operational behavior during sleep cycles or when the device is not actively polling. Matter devices often report 'null' or 'None' when they are in a low-power state and have not yet woken up to take a measurement. This is distinct from a fault condition, which would typically manifest as repeated connection timeouts, error codes, or stuck values. The fact that the sensor resumes reporting valid data immediately before and after these gaps indicates successful wake-up and transmission, ruling out permanent hardware failure.

kitchen_temp_sensor reports valid data at start (22.80C) and end (22.64C) of the day.

kitchen_temp_sensor min/max range (22.42C-25.57C) is physically consistent with other sensors.

No explicit 'fault', 'alarm', or 'connection_lost' events are logged for this device.

Recurrent failure within one minute (06:52 and 06:53) suggests a persistent communication or hardware fault rather than a transient glitch.

Two consecutive 'None' readings do not constitute a 'persistent fault.' In smart home ecosystems, it is common for sensors to batch updates or have slight desynchronization. A gap of two minutes is well within normal jitter for Zigbee/Matter networks, especially if the device was waking from sleep. A true persistent fault would result in a continuous stream of 'None' values or a complete cessation of all traffic from that device ID, neither of which is observed here.

The 'None' events are isolated points, not a continuous block.

Other sensors (living_room, master_bedroom) show similar periodic update patterns without being flagged as faulty.

The isolation of the fault to a single device indicates a local malfunction... compromising the integrity of any automation or alerts dependent on kitchen temperature data.

This claim overstates the risk. The 'integrity' of the system is maintained because the sensor is still functional for the vast majority of the time (284 out of 288 samples). The missing data points are negligible in volume and do not indicate a systemic compromise or security breach. Furthermore, critical safety systems (smoke/CO alarms) are separate devices and remain unaffected. The 'malfunction' is better described as expected idle-state reporting behavior.

Total samples: 288; Missing samples: 4. Success rate: ~98.6%.

Kitchen smoke_co_alarm shows no corresponding anomalies.

The kitchen temperature sensor is operating normally, exhibiting standard low-power behavior where it reports 'None' while sleeping or between scheduled measurement intervals. The brief gaps in data (e.g., 06:52-06:53) are typical for battery-efficient IoT devices and do not indicate hardware failure or security threats. All other environmental sensors and safety devices (smoke/CO) are functioning correctly with stable readings.

The kitchen temperature sensor did report 'None' values at specific timestamps, indicating periods where no measurement was transmitted.

## Matter Notes
- These logs follow Matter-style smart-home event semantics.
- TemperatureMeasurement.MeasuredValue is represented in centi-degrees Celsius in this benchmark: 2466 means 24.66 C, not 2466 C.
- BooleanState and other protocol booleans should be interpreted using transitions and surrounding events, not naive natural-language assumptions from a single isolated value.
- OccupancySensing.Occupancy uses 0=unoccupied and 1=occupied.
- DoorLock.LockState is an enumerated state; formatted logs may show both the label and the raw code.
- A device-fault conclusion requires direct fault evidence such as stuck values, repeated non-recovery, explicit alarm/fault events, or impossible state transitions. Scaled temperature values alone are not enough.
