DF-06-FP: 窗帘正常移动但速度慢

strong - The prosecution explicitly states 'no_case' and provides evidence showing normal operation for the specific sensors in question.

strong - The defense corroborates the prosecution's findings with detailed statistical support (min/max temps, update frequencies) confirming normal behavior.

The Prosecutor's own verdict is 'no_case', which triggers Decision Rule 4. Additionally, both sides agree that the master bedroom sensors are functioning normally.

No anomaly detected; master bedroom temperature and occupancy sensors are operating within normal parameters.

Continue routine monitoring of IoT devices.

No immediate action required for master bedroom sensors.

Question: 请检查以下设备状态历史，判断 master_bedroom 区域的传感器 是否工作正常。如果异常，请说明可能的故障类型。

Explanation: The master_bedroom temperature sensor (`master_bedroom_temp_sensor`) exhibits normal operational behavior. It reports valid temperature values (e.g., 25.47°C at 08:35, 25.53°C at 10:00, 24.96°C at 13:35) that are consistent with other sensors in the home and show expected diurnal variation (spanning ~3.16°C). There are no 'None' values or error flags associated with this specific device in the Alert/Error Events log.

Explanation: The master_bedroom occupancy sensor (`master_bedroom_occupancy`) is functioning correctly. It transitions between occupied and unoccupied states logically throughout the day, with a high number of updates (228) and occupied events (215), indicating active detection rather than a stuck state. The summary confirms it was unoccupied at 00:00-05:30 and occupied during later hours, which aligns with typical human activity patterns.

[2026-06-22T20:54:00] master_bedroom_occupancy | OccupancySensing.Occupancy = occupied (raw=1)

No evidence of anomaly was found for the master_bedroom sensors. Both the temperature and occupancy sensors report valid, consistent data with no error codes, stuck values, or impossible transitions. The only sensor errors in the log belong to the kitchen temperature sensor, not the master bedroom.

The master_bedroom temperature sensor exhibits normal operational behavior with valid values and expected diurnal variation.

I fully agree. The temperature data for `master_bedroom_temp_sensor` shows a logical range (22.41°C to 25.57°C) consistent with other indoor sensors in the home. There are no missing values (`None`) or error flags associated with this specific device, unlike the kitchen sensor which did report errors. The net change is minimal (-0.05°C), indicating stability rather than drift or failure.

Temperature Trends: master_bedroom_temp_sensor min=22.41C, max=25.57C, samples=288

Alert / Error Events: No entries for master_bedroom_temp_sensor

The master_bedroom occupancy sensor is functioning correctly, transitioning logically with high update counts (228 updates, 215 occupied events).

This is correct. The high frequency of updates (approx. every 4 minutes on average across the day) combined with the transition from 'unoccupied' at night (00:00-05:30) to 'occupied' during the day aligns perfectly with typical human sleep/wake cycles. There is no evidence of a 'stuck' state (e.g., remaining occupied for 24 hours without change) or total silence.

Occupancy Summaries: master_bedroom/master_bedroom_occupancy occupancy_updates=228, occupied_events=215

Key Events: master_bedroom/master_bedroom_occupancy | OccupancySensing.Occupancy=0 at 00:00:00 through 05:30:00

The master bedroom sensors are operating within normal parameters. The temperature sensor reports stable readings consistent with the rest of the house, and the occupancy sensor accurately reflects a standard daily routine of sleeping at night and being active during the day. No anomalies or faults are present in the logs for these specific devices.

The Prosecutor's conclusion that the master_bedroom sensors are normal is accurate and supported by the evidence.

## 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.

DF-01-FP: 空调恒温控制导致温度稳定

有微小波动（±0.2°C），不是完全固定值；且空调处于开启状态

strong - The prosecution explicitly states 'no_case' and provides evidence showing normal operational behavior for the living room sensors, contrasting them with a faulty kitchen sensor.

strong - The defense corroborates the prosecution's findings, providing detailed explanations for why the data represents normal human activity and environmental conditions, supported by log comparisons.

The Prosecutor's explicit declaration of 'no_case' combined with the lack of any direct evidence of anomaly or unsafe sequences in the logs.

No security threat detected; living room sensors are operating within normal parameters.

Investigate the isolated faults in the kitchen temperature sensor separately.

2026-06-03T19:10:00 | kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None

Explanation: The living_room_occupancy sensor shows normal operational behavior with 105 updates and 68 occupied events, transitioning between occupied (1) and unoccupied (0) states consistent with human activity patterns. The temperature sensor reports values within a normal residential range (22.42°C to 25.57°C) with smooth transitions and no stuck values or impossible jumps.

living_room_temp_sensor: min=22.42C, max=25.57C, span=3.15C

Explanation: While the kitchen temperature sensor exhibits faults (null values), there is no evidence of similar malfunction in the living room sensors. The living room sensors function correctly alongside other healthy devices in the same environment.

kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None at multiple timestamps

living_room/living_room_temp_sensor | TemperatureMeasurement.MeasuredValue = 25.42 C (raw=2542)

No direct evidence of anomaly was found for the living room sensors. The occupancy sensor demonstrates valid state transitions corresponding to user presence, and the temperature sensor provides stable, physically plausible readings. Although the kitchen temperature sensor failed, this isolated fault does not implicate the living room devices, which are operating within expected parameters.

The prosecution correctly identifies that the occupancy sensor is functioning. The data shows a healthy ratio of occupied to unoccupied time (68/105 updates are occupied), and the transitions align with typical daily rhythms (unoccupied at night, occupied during day/evening). There are no signs of 'stuck' states or rapid flickering indicative of hardware failure.

Key Events show consistent 'unoccupied' status from 00:00 to 05:30, followed by activity in later chunks.

The temperature readings for the living room sensor are physically plausible and consistent with other sensors in the home. The span of ~3.15°C reflects natural diurnal variation or HVAC cycling, not sensor error. Crucially, there are no null values or error codes associated with this specific device, unlike the kitchen sensor which had explicit fault events.

living_room_temp_sensor: min=22.42C, max=25.57C, span=3.15C

Comparison with master_bedroom_temp_sensor (min=22.41C, max=25.57C) shows correlated environmental conditions.

Absence of 'MeasuredValue=None' events for living_room_temp_sensor in Alert/Error Events.

This is a correct distinction. The kitchen sensor failures are isolated incidents (4 nulls) likely due to local connectivity or power issues in that specific zone. The living room sensors do not share these fault indicators. The presence of faults in one area does not imply systemic failure in another without further evidence.

Alert / Error Events list only kitchen/kitchen_temp_sensor nulls.

Living room chunks (C10, C15, C17, C23, C25, C27) all contain valid temperature readings from living_room_temp_sensor.

The living room sensors are operating normally. The occupancy sensor accurately tracks presence, showing expected periods of absence (nighttime) and presence (daytime/evening). The temperature sensor provides stable, realistic readings that correlate with other rooms, indicating no hardware defects or calibration errors. The faults observed in the kitchen are isolated to that device and do not affect the living room infrastructure.

## 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.

strong - The Prosecutor explicitly states 'no_case' and provides indirect evidence showing normal sensor behavior in the bathroom, while noting faults are isolated to the kitchen.

strong - The Defender corroborates the normal operation of bathroom sensors with specific log timestamps correlating occupancy and light states, and correctly identifies that kitchen faults are irrelevant to the bathroom scope.

The Prosecutor's own verdict is 'no_case', which triggers Decision Rule 4. Additionally, both sides agree that the bathroom sensors are functioning normally and any detected anomalies are confined to the kitchen.

No anomaly detected in the bathroom area; reported faults are isolated to the kitchen temperature sensor.

Monitor kitchen temperature sensor for continued malfunction.

No immediate action required for bathroom devices.

Explanation: The bathroom occupancy sensor (`bathroom_occupancy`) shows normal operational behavior: it transitions from 'unoccupied' (0) to 'occupied' (1) at 08:55:00 when the user enters, and returns to 'unoccupied' (0) at 09:19:22 upon exit. This pattern is consistent with typical human usage duration (~24 minutes). There are no stuck values, impossible state transitions, or explicit fault alarms associated with the bathroom devices.

[2026-06-07T09:19:22] bathroom/bathroom_occupancy | OccupancySensing.Occupancy=0

Explanation: While the kitchen temperature sensor exhibits faults (returning `None`), these events are isolated to the kitchen device and do not involve any bathroom sensors. The query specifically asks about the bathroom area, where all reported devices (light, occupancy) function within expected parameters.

[2026-06-07T09:19:10] kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None

No evidence of anomaly was found in the bathroom area sensors. The occupancy sensor correctly tracked entry and exit events, and the light switch responded appropriately. The only sensor faults detected were in the kitchen temperature sensor, which is outside the scope of the requested investigation for the bathroom.

The bathroom occupancy sensor shows normal operational behavior: it transitions from 'unoccupied' (0) to 'occupied' (1) at 08:55:00 when the user enters, and returns to 'unoccupied' (0) at 09:19:22 upon exit. This pattern is consistent with typical human usage duration (~24 minutes).

The Prosecutor correctly identifies that the single observed event for the bathroom occupancy sensor is logically sound. The transition from 0 to 1 coincides with the bathroom light turning on (08:55:00), and the return to 0 occurs after a reasonable duration of use, followed by the light turning off (09:18:00). There is no evidence of stuck states or impossible transitions in the provided logs.

[2026-06-07T09:19:22] bathroom/bathroom_occupancy | OccupancySensing.Occupancy=0

I concede that the kitchen temperature sensor has reported `None` values multiple times, indicating a potential fault in that specific device. However, this is irrelevant to the health status of the bathroom sensors. The query specifically asks about the bathroom area. The logs show no errors, warnings, or anomalous data patterns for the bathroom water leak detector, light, or occupancy sensor. The absence of error logs for bathroom devices supports the conclusion that they are functioning normally.

Alert / Error Events list contains only kitchen/kitchen_temp_sensor entries.

No 'bathroom' entries appear in the Alert / Error Events section.

The bathroom sensors are operating within normal parameters. The occupancy sensor recorded a single valid entry/exit cycle in the morning, correlated with the light being turned on and off. No other activity was detected in the bathroom during the rest of the day, which is consistent with low-usage periods. The faults identified in the report belong exclusively to the kitchen temperature sensor and do not impact the bathroom equipment.

The kitchen temperature sensor (`kitchen_temp_sensor`) is indeed faulty, as evidenced by multiple `MeasuredValue=None` events.

## 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.

状态 vs 实际位置不一致

strong - The prosecution explicitly states 'no_case' and provides direct evidence that the specific devices in question (bedroom sensors) are functioning normally with valid data ranges and logical state transitions.

strong - The defense fully agrees with the prosecution's assessment, providing corroborating log entries that confirm normal operation for both temperature and occupancy sensors.

The Prosecutor's own verdict is 'no_case', which triggers Decision Rule 4. Additionally, there is no evidence of anomaly for the bedroom sensors; the only faults mentioned are isolated to the kitchen sensor, which is irrelevant to the specific query about the bedroom area.

No security or operational anomaly was detected in the bedroom area sensors; they are operating within normal parameters.

Continue routine monitoring of bedroom sensors.

Investigate the kitchen temperature sensor separately as it exhibits malfunction symptoms.

2026-06-19T19:41:00 | kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None

Explanation: The bedroom temperature sensor (`bedroom_temp_sensor`) exhibits normal operational characteristics: it reports periodic updates (every 5 minutes), values fluctuate within a realistic range for an indoor environment (21.42°C to 24.59°C), and there are no 'None' or error values reported for this specific device in the provided logs. The Matter notes explicitly state that scaled temperature values alone are not sufficient for a fault conclusion, and no direct fault evidence (stuck values, repeated non-recovery, explicit alarms) is present for the bedroom sensor.

[2026-06-19T00:00:00] bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 21.72 C (raw=2172)

[2026-06-19T05:40:00] bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 23.60 C (raw=2360)

[2026-06-19T18:10:00] bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 22.28 C (raw=2228)

Explanation: While the kitchen temperature sensor shows intermittent `None` values (potential malfunction), the query specifically asks about the *bedroom* area sensors. The bedroom occupancy sensor also functions correctly, transitioning between occupied/unoccupied states consistent with user activity (e.g., waking up at 06:29). There is no evidence linking the kitchen sensor's issues to the bedroom sensors.

[2026-06-19T06:29:00] bedroom/bedroom_occupancy | OccupancySensing.Occupancy=1

[2026-06-19T06:31:42] bedroom/bedroom_occupancy | OccupancySensing.Occupancy=0

No anomaly detected for the bedroom area sensors. The bedroom temperature sensor reports valid, fluctuating data without errors, and the occupancy sensor transitions logically with user presence. Although the kitchen temperature sensor shows signs of malfunction (missing values), this does not implicate the bedroom devices.

The bedroom temperature sensor exhibits normal operational characteristics: it reports periodic updates, values fluctuate within a realistic range, and there are no 'None' or error values.

I fully agree with this assessment. The data for `bedroom_temp_sensor` shows consistent reporting intervals (every 5 minutes) and physically plausible temperature variations (21.4°C to 24.6°C). Unlike the kitchen sensor which had missing values, the bedroom sensor maintained a complete data stream without gaps or impossible readings. This confirms the device is functioning correctly.

[2026-06-19T00:00:00] bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 21.72 C (raw=2172)

[2026-06-19T05:40:00] bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 23.60 C (raw=2360)

[2026-06-19T22:30:00] bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 21.57 C (raw=2157)

The bedroom occupancy sensor functions correctly, transitioning between occupied/unoccupied states consistent with user activity.

This is also correct. The occupancy logs show logical transitions corresponding to typical human behavior: waking up in the morning (06:29), brief movements, and returning to unoccupied states at night. There are no stuck states or erratic toggling that would suggest hardware failure or interference.

[2026-06-19T06:29:00] bedroom/bedroom_occupancy | OccupancySensing.Occupancy=1

[2026-06-19T06:31:42] bedroom/bedroom_occupancy | OccupancySensing.Occupancy=0

[2026-06-19T22:24:21] bedroom/bedroom_occupancy | OccupancySensing.Occupancy=1

The bedroom sensors (temperature and occupancy) are operating normally. The temperature sensor provides stable, continuous readings within expected indoor ranges, and the occupancy sensor accurately reflects presence patterns. Any anomalies detected in the system logs (specifically missing values) are isolated to the kitchen temperature sensor and do not affect the integrity of the bedroom devices.

The kitchen temperature sensor did exhibit faults (missing values), but this is irrelevant to the specific query about the bedroom area.

## 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.
