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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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。

## 任务
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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。

    "3. 环境背景分析：虽然此时段（凌晨 3:00-4:00）所有房间的运动传感器均显示 Occupancy=0（无人），但这并不能排除火灾风险。相反，深夜无人时发生火灾更为危险，因为可能无法及时察觉和处理。",
    "4. 温度数据辅助判断：客厅温度传感器读数在报警前后维持在 23°C - 24°C 左右（Matter 协议中通常单位为 0.01°C，即 23.27°C 等），未见急剧升高，这可能意味着火势尚处于初期、烟雾扩散较快而热量未显著积聚，或者传感器位置距离火源有一定距离，但烟雾探测已生效。"

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. 识别关键异常事件：日志中明确记录了 `kitchen_smoke_alarm` 的 `SmokeCoAlarm.ContaminationState` 属性变化。8月6日08:00为1（通常表示轻度污染或需清洁），8月7日08:00为2（中度污染或持续故障），8月8日08:00为3（严重故障或电池耗尽/传感器失效）。",
    "2. 排除误报干扰：虽然8月6日和7日早晨有灶具使用记录（cook_surface OnOff=True），但日志中并未出现火灾报警（Fire State）或一氧化碳报警（CO State），仅出现了污染状态（Contamination State）。这说明之前的烹饪活动可能产生了少量油烟触发了传感器的自诊断机制，或者传感器本身老化积灰，但并未发生真实火灾。",
    "3. 确认威胁性质：Matter协议中 SmokeCoAlarm Cluster 的 ContaminationState 用于指示传感器是否因灰尘、昆虫或老化而需要维护。状态从1升级到2再到3是一个典型的设备退化过程，意味着该安全设备已无法可靠地检测烟雾或一氧化碳，构成了严重的“安全设备失效”风险。",
    "4. 综合评估：尽管家庭其他区域（如卧室、客厅）的温度和 occupancy 数据看起来正常，没有人员跌倒或入侵迹象，但厨房作为高风险区域（有灶具），其核心安全防线（烟感）处于失效状态，因此判定为高置信度的安全威胁。"

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。

    "2. 验证是否存在真实火源：虽然7月29日07:10有 `kitchen_cook_surface` (灶具) 开启的记录，但此时并未伴随烟雾报警器的 `AlarmState` (如烟雾浓度超标) 触发，仅记录了污染状态。且该烹饪行为发生在早上7点多，随后温度传感器读数平稳上升，未见异常高温激增，表明没有发生严重的燃烧事故。",

    "1. 关键警报触发：日志显示在 03:16:00，厨房烟雾报警器（kitchen_smoke_alarm）的 SmokeState 变为 1（报警状态），同时客厅烟雾报警器因互联机制也触发了 InterconnectSmokeAlarm 和 ExpressedState 为 1。这是明确的火灾或烟雾威胁信号。",
    "2. 伴随环境异常：在烟雾报警前后（02:20 - 05:15），厨房、客厅及卧室的温度传感器读数均呈现非自然的持续上升趋势。例如，厨房温度从 2330 升至 2407+，客厅从 2342 升至 2453+。这种全屋性的缓慢升温通常不是正常的生活波动，而是与热源（如火灾、未关闭的加热设备）相关的特征。",
    "3. 排除误报可能性：虽然独居老人在凌晨可能处于睡眠状态（所有 occupancy 均为 0），但烟雾报警器的触发结合温度的系统性升高，使得“传感器故障”或“误报”的可能性降低。如果是单纯的传感器漂移，通常不会导致 SmokeCoAlarm 的状态位翻转；如果是烹饪遗留问题，温度上升和烟雾报警是典型的后果。考虑到老人独居且凌晨无活动，若为真实火情，风险极高。"

System:
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。
