## 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",

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。

## 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",

```

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。

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。

  "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",

    "2. 在18:55时，读数突然跳变为2305，而前一时刻（18:40）为2294，后一时刻（19:10）又降至2297。虽然2305与2294差距不大，但结合上下文看，整体趋势是持续降温。",
    "3. 关键异常点出现在20:05-20:10：此时其他房间（如主卧、次卧）温度已降至2250-2270区间，且厨房自身在19:50读数为2266。然而，在20:05和20:10，厨房传感器读数分别反弹至2272和2277，出现了明显的‘逆温’现象，即环境温度在下降过程中局部突然升高，这与物理常识不符（除非有热源开启，但灶具已在18:37关闭）。",
    "4. 20:10之后，读数迅速回落并与其他房间趋势一致（20:25为2270，20:45为2265等）。这种短暂的、无外部事件（如烹饪、开窗）触发的数值反向波动，强烈暗示传感器硬件故障、校准漂移或通信数据包损坏。"

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
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",

  ],
  "recommended_actions": [

}
```

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。

  "reasoning": [
    "1. 分析温度数据趋势：在13:00之前，客厅温度从25°C左右缓慢下降至24.9°C，符合夏季午后自然降温或空调运行后的正常物理规律。",
    "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29.2°C、29.4°C和29.6°C的数值。这些数值不仅远高于当前环境温度（其他房间如厨房、卧室均在24-25°C左右），且与前后时刻的读数（24.9°C -> 29.2°C -> 24.8°C）形成剧烈跳变，不符合热惯性原理。",
    "3. 关联设备状态：值得注意的是，在第一次异常读数前（13:00），客厅空调被开启（OnOff=True）。如果传感器真实检测到高温，空调应持续高功率运行；但随后温度读数又迅速回落至正常范围，说明之前的“高温”是虚假信号。这种间歇性的错误读数会导致智能家居系统误判环境状态，可能导致空调频繁启停或制冷不足。",
    "4. 排除其他因素：入户门运动传感器在13:09-13:49期间持续触发（Occupancy=1），但这通常意味着有人进出或徘徊，若真有人体热源导致局部升温，不会造成整个客厅传感器读数瞬间飙升几度后又立即恢复正常，且其他房间传感器未受影响，故排除人体热源影响，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
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",

```

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。

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",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "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。

  "threat_description": "客厅温度传感器出现间歇性极高数值跳变（约29.2°C-29.6°C），与周围环境和空调运行状态严重不符，疑似传感器故障或数据上报错误。",
  "reasoning": [
    "1. 环境背景分析：日志显示时间为7月18日白天，且living_room_ac在13:00开启制冷。此时段室内其他区域（如主卧、厨房、儿童房）的温度读数均在24°C-25°C左右，并呈现随空调运行逐渐下降的趋势（例如15:45主卧降至24.04°C）。这表明家庭整体环境温度适宜且正在被有效冷却。",
    "2. 异常数据识别：客厅温度传感器(living_room_temp_sensor)在13:15、13:35、13:55三个时间点分别上报了29.20°C、29.40°C、29.60°C的数值。这些数值不仅显著高于同一时刻的其他房间（高出约4-5°C），也远高于该时间段应有的室温水平。",
    "3. 逻辑矛盾验证：如果客厅真实温度真的升至29°C以上，作为主要降温区域的客厅，其温度理应是最高的或者至少与其他未开空调区域持平，但数据显示其他房间温度更低。更关键的是，在空调开启后，其他房间温度持续下降，而客厅传感器却反复报出高温峰值，随后又瞬间回落至正常范围（如13:40回落至24.82°C）。这种非物理性的剧烈波动和与环境热力学规律相悖的数据，排除了真实高温的可能性。",
    "4. 结论：排除人为误读或短暂热源干扰（因为间隔20分钟重复出现且幅度巨大），判定为传感器硬件故障、校准失效或通信模块产生的数据毛刺。"

    "13:55 living_room_temp_sensor 再次报值 2960 (29.6°C)，形成周期性异常尖峰。",

  "recommended_actions": [
    "检查客厅温度传感器的电池电量及安装位置，确认是否靠近发热源或阳光直射导致局部过热（尽管数据跳变特征更像电子故障）。",
