你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

    "推理步骤 3: 尽管灶具在 19:49:00 被关闭 (False)，但高温读数并未立即回落，且期间卧室和客厅的温度也出现异常波动（如 19:10 客厅温度骤降至 2287，与整体环境趋势不符，可能受干扰或传感器漂移影响），结合厨房的极端高温，极大概率是传感器故障导致误报，或者发生了真实的火灾/过热事件导致传感器损坏。无论哪种情况，都构成了极高的安全风险。"
  ],
  "key_evidence": [
    "19:03:30 灶具开启后，厨房温度在 40 分钟内从 ~248 度升至 ~268 度。",

    "19:50:00 温度传感器突然返回 None，表明设备可能因过热而失效或断电。"

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "threat_description": "客厅温度传感器出现间歇性极高数值读数（约29.2°C-29.6°C），与同一时间段内其他房间及空调运行状态下的正常室温趋势严重不符，疑似传感器故障或数据上报错误。",
  "reasoning": [
    "1. 建立基准：在13:00之前，客厅温度传感器读数在25.0°C-25.5°C之间波动，且随着时间推移和空调开启（13:00 OnOff=True），整体环境温度呈下降趋势（从~25°C降至~24°C以下），符合夏季开空调的逻辑。",
    "2. 识别异常点：在13:15、13:35和13:55三个时间点，客厅温度传感器突然上报了2920 (29.2°C)、2940 (29.4°C) 和 2960 (29.6°C) 的数值。",
    "3. 排除环境因素：在同一时间段（13:15-13:55），厨房温度传感器读数从25.08°C降至24.81°C，主卧从25.08°C降至24.86°C，次卧从24.83°C降至24.75°C。所有其他区域温度均在24-25°C左右并持续下降，证明室内实际环境温度并未升高至29°C以上。",
    "4. 结合设备状态：客厅空调在13:00开启，若室温真升至29°C，空调应全速制冷，但其他传感器显示室温在降低，说明空调工作正常且有效。因此，29°C+的读数极不可能是真实物理温度。",
    "5. 结论：这种孤立的、与其他所有传感器及逻辑相悖的高值读数，是典型的传感器硬件故障、校准漂移或通信数据包损坏导致的误报。"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "threat_description": "卧室温度传感器读数出现严重异常漂移，数值远超正常室温范围（显示约24.35°C至24.57°C的整数部分，但原始值为2435-2457，若单位为0.1度则合理，但结合其他传感器及上下文，此处更可能是数据解析或传感器故障导致的读数异常，或者如果单位是0.01度则高达243度C，显然错误。根据Matter标准TemperatureMeasurement通常以厘氏度(0.01°C)为单位，2435代表24.35°C是合理的室温。然而，观察日志中所有温度传感器的值都在2200-2550之间，即22-25.5°C，这是非常正常的夏季室内温度。因此，重新评估：如果单位是0.01°C，则2435=24.35°C，完全正常。如果单位是0.1°C，则2435=243.5°C，不可能。Matter协议中TemperatureMeasurement.MeasuredValue的单位是centi-degrees Celsius (0.01°C)。因此，2435表示24.35°C。所有传感器读数均在22-25.5°C之间，符合夏季空调开启后的正常室温波动。但是，题目要求判断“目标设备”即bedroom_occupancy的状态。让我们重新聚焦于bedroom_occupancy。",

    "2. 识别异常模式：从00:00到08:00，卧室 occupancy 呈现明显的周期性闪烁（每1小时切换一次状态：0->1->0->1...）。这种高频、规律性的状态翻转不符合人类正常的睡眠或活动习惯（人不会每小时准时醒来又睡去）。",
    "3. 排除环境干扰：虽然凌晨时段可能有宠物活动，但如此精确的每小时间隔且持续数小时的交替，极大概率指向传感器硬件故障、固件bug或信号干扰导致的误报。",
    "4. 对比其他设备：客厅 occupancy 在夜间大部分时间为0，仅在白天活跃，符合正常作息。厨房和卫生间传感器也未显示类似的异常高频闪烁。",
    "5. 结论：卧室运动传感器存在严重的误触发或状态锁定问题，导致系统错误地认为有人在卧室频繁进出或停留，属于传感器故障/漂移。"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",

  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "threat_description": "卧室温度传感器出现异常读数（-500）及随后剧烈的温度骤降，表明设备可能存在硬件故障或数据上报错误。",
  "reasoning": [
    "1. 识别异常数据点：在 2026-07-18T14:05:00，bedroom_temp_sensor 上报了 TemperatureMeasurement.MeasuredValue = -500。根据 Matter 协议标准，TemperatureMeasurement 的 MeasuredValue 单位为厘氏度（centi-degrees Celsius），即实际温度为 -5.00°C。然而，在同一时刻前后，该房间及其他房间的温度均在 23-25°C 左右（如 14:00 为 24.30°C，14:10 为 23.75°C）。-5°C 对于室内环境极不合理，且通常传感器故障会返回 null、0 或特定的错误码，而非一个看似有效但极度偏离环境的数值，这属于典型的数据异常或传感器内部逻辑错误。",
    "2. 分析后续趋势异常：在异常值 -500 之后，温度读数并未恢复平稳，而是呈现非自然的快速下降趋势：从 14:10 的 23.75°C 降至 14:45 的 23.58°C，再到 15:20 的 23.35°C，直至 17:55 的 22.29°C。虽然下午气温可能略有下降，但在短短几小时内，卧室温度持续单调递减且幅度较大，结合之前的 -500 异常点，强烈暗示该传感器存在漂移（drift）或校准失效问题。",
    "3. 排除环境因素：客厅和厨房的温度传感器在同一时间段内显示相对稳定或正常的日间波动（例如客厅从 25.53°C 缓慢降至 23.42°C），没有表现出与卧室同步的剧烈变化。此外，卧室 occupancy 传感器在 14:29 和 15:14 等时间点仍报告有人（Occupancy=1），排除了因无人导致窗户长时间开启造成极端降温的可能性（即使开窗，也不会瞬间产生 -500 的错误码）。因此，判定为传感器自身故障。"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

    "推理步骤 2: 结合环境上下文分析，虽然阳台门传感器和入户门传感器频繁触发 (Occupancy=1)，但这与日志中多次记录的入户门锁手动操作 (LockOperation) 及玄关区域人员活动一致，属于正常的家庭日常出入模式，并非入侵迹象。",
    "推理步骤 3: 温度传感器数据显示室内温度随时间自然波动（早晨至中午逐渐升高），符合夏季上午的自然热力学规律，且厨房温度虽高但未达到危险阈值，烟雾报警器等安全设备未触发警报，整体环境安全。"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

    "1. 分析温度数据量级：日志中 `living_room_temp_sensor` 的 `TemperatureMeasurement.MeasuredValue` 在 03:10 至 11:05 期间持续在 2367 到 2556 之间波动。",
    "2. 结合 Matter 协议标准判断：Matter 协议中的 Temperature Measurement Cluster 通常使用厘氏度（centi-degrees Celsius）作为单位，即 1 个单位 = 0.01°C。若按此标准，2400 代表 24.00°C，这是非常合理的室内温度。",
    "3. 识别异常模式：然而，同一时间段内其他房间（如卧室、厨房）的温度传感器读数也出现在 2385-2550 区间。如果所有传感器都报告 2400+ (24°C)，这本身是可能的。但关键在于 `living_room_window_contact` 和 `living_room_window` 的状态变化。",
    "4. 关联设备状态与逻辑矛盾：在 09:10，客厅窗户被打开（Contact=True -> False），窗帘位置为 0（关闭）。通常开窗会导致局部温度快速下降或波动。但观察 09:10 前后的温度数据：09:05 为 2550，09:10 为 2539，09:45 为 2551。温度并未因开窗而显著下降，反而维持在高位震荡。",
    "5. 核心故障判定：更严重的异常在于数值的“非自然”稳定性与高位。虽然 24-25°C 是合理室温，但注意看 03:10 的 2378 和 04:30 的 2420 等数值，这些数值如果是摄氏度（即 2378°C），显然是传感器硬件故障或固件解析错误（例如将毫伏值直接当作摄氏度上报，或者小数点错位）。考虑到智能家居场景，2378°C 是不可能的，因此极有可能是传感器发生了 **Sensor Malfunction**（传感器故障），具体表现为读数溢出、单位配置错误或硬件损坏导致输出无效高温值。即使假设单位是厘氏度，该传感器与其他传感器相比，其波动模式缺乏物理合理性（如夜间无热源时不应如此稳定高位，且未受空调明显影响）。最可能的解释是传感器读数未经过正确的单位转换或校准，导致显示/记录为异常高值。"
