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。

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。

    "虽然日志中未直接显示火灾报警（Alarm State），但持续的污染状态升级表明设备维护缺失。如果传感器被严重污染，可能在真正发生火灾时无法正确响应，或在无火情时产生误报，构成安全隐患。",
    "排除其他威胁：温度数据在正常范围内波动（约25°C），无异常高温；门锁操作为手动且符合日常作息；运动传感器均为0，表明无人活动，排除了入侵或跌倒风险。"

    "推理步骤 4: 结合住户习惯，虽然日志显示有人进入（门锁操作）和开灯，但并未看到明显的灶具开启记录或大量油烟产生的其他迹象，这种‘静默’的高温加烟雾报警更符合设备故障（如油垢积聚自燃）或长期未清洁导致的火灾隐患，而非正常的烹饪过程。"

请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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",

    "2. 验证联动机制：紧接着在 03:16:00 和 03:17:00，`living_room_smoke_alarm` 的 `InterconnectSmokeAlarm` 和 `ExpressedState` 均变为 1，这符合 Matter 协议中烟雾报警器互联报警的标准行为，确认了警报的真实性而非单一设备误报。",
    "3. 排除正常干扰：虽然凌晨 3 点处于睡眠时段，但所有房间的运动传感器（Occupancy）均为 0，说明屋内无人活动。这种“无人+烟雾报警”的组合排除了烹饪、吸烟等日常人为因素导致的短暂烟雾，增加了真实火灾或设备故障引发火灾的风险等级。",
    "4. 温度趋势分析：虽然客厅温度传感器读数（如 2395 代表 23.95°C）在报警前后略有波动，但未出现急剧升温，这可能意味着烟雾已扩散至客厅，或者火灾初期主要产生烟雾而非大量热量，但这不影响对烟雾报警事件的定性。"

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",
  "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。
