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",

    "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。

    "1. 分析温度数据趋势：在2026-07-26这一天，客厅温度传感器（living_room_temp_sensor）的读数大部分时间在2381-2556之间波动，符合夏季室内正常温度范围（约23.8°C - 25.6°C）。",
    "2. 识别异常尖峰：然而，在13:15、13:35和13:55三个时间点，传感器突然上报了2920、2940和2960的数值（即29.2°C - 29.6°C）。",
    "3. 排除环境因素：在同一时间段内，厨房温度传感器读数在2484-2501之间，卧室温度传感器读数在2384-2388之间，均处于正常且稳定的状态。如果客厅真的升温至近30度，其他房间也应有所反映，或者空调应有明显反应。",
    "4. 结合设备状态：虽然客厅空调在13:00开启，但随后的温度读数并未呈现平滑下降曲线，而是出现了剧烈的、不连续的跳变（如13:15的2920后紧接着13:25的2489），这种非物理性的剧烈波动不符合热力学惯性，表明是传感器本身的数据采集或传输故障。"

## 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。

    "2. 对比其他房间传感器：同一时间段内，客厅和卧室的温度变化平缓且符合物理规律（如傍晚自然降温或空调影响），而厨房传感器在短时间内出现超过 1°C 的非线性剧烈波动以及数据中断，这不符合环境温度变化的正常特征。",
    "3. 排除烹饪干扰：虽然 18:15-19:00 可能是晚餐准备时间，但 19:00 的 'None' 状态表明设备可能经历了重启、电池耗尽或信号严重丢包，而非单纯的数值漂移。这种间歇性失效属于典型的传感器故障。"

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。

    "1. 分析温度数据趋势：在06:04开启灶具后，厨房温度传感器读数从正常的2481迅速飙升至2504、2514等数值。虽然烹饪会产生热量，但Matter协议中TemperatureMeasurement.MeasuredValue通常以厘度（centi-degrees）为单位，即2500代表25.00°C。然而，日志中显示的值如2552、2539等在短时间内剧烈波动，且部分时刻（如06:05:10）直接返回None，表明传感器通信不稳定或内部逻辑错误。",
    "2. 对比其他传感器：同一时间段内，客厅和卧室的温度传感器读数稳定在24-25°C左右（例如living_room_temp_sensor在2514-2553之间波动，考虑到距离热源较远，此数值略高但尚在合理范围，可能是全屋升温），而厨房作为热源区域，其传感器读数不仅高于其他房间，还出现了非连续性的跳变和空值。",
    "3. 排除正常行为：独居老人在早晨做饭是正常行为，但传感器在关闭灶具后（06:39之后）并未呈现自然的冷却曲线，而是继续报告高位数值（2500+），且伴随数据丢失（None）。这种不稳定的读数模式不符合物理规律，指向传感器本身存在故障（如校准失效、元件损坏或连接问题）。"

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

  "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",

## 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。

## 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: ..."

    "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严重的读数跳变和异常高温值，疑似硬件故障或数据上报错误。",
  "reasoning": [
    "1. 分析温度数据的合理性：日志显示客厅温度传感器在大部分时间读数在 2300-2550 (即 23.0°C - 25.5°C) 之间波动，符合夏季室内舒适温度范围。然而，在 13:15、13:35 和 13:55 三个时间点，该传感器突然上报了 2920、2940 和 2960 (即 29.2°C - 29.6°C) 的数值。",
    "2. 验证环境一致性：在同一时间段（13:15-13:55），厨房温度传感器读数从 2508 降至 2474，卧室温度传感器维持在 2390 左右。其他房间并未出现同步的高温现象，且空调在 13:00 开启，通常会导致室温下降而非剧烈上升。这表明 29°C+ 的读数与整体家庭环境温度不符。",
    "3. 检查设备状态关联：虽然客厅 occupancy 传感器在此期间持续报告有人（Occupancy=1），但这无法解释温度的非逻辑性飙升。结合读数呈现出的离散性尖峰（而非平滑过渡），这极有可能是传感器内部元件故障、校准失效或通信数据包损坏导致的“脏数据”。"
