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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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。

    "1. 识别关键异常模式：日志显示在2026-08-11、08-12、08-13的同一时刻（08:00:00），kitchen_smoke_alarm 均报告了 SmokeCoAlarm.ContaminationState 的变化（分别为1, 2, 3）。这种高度规律性的重复事件通常不是随机故障，而是指向特定的设备状态机问题或环境干扰。",
    "2. 排除真实火灾/燃气风险：虽然烟雾报警器报警，但同一时间段内 kitchen_cook_surface（灶具）仅在8-11日06:50关闭过一次，后续几天无烹饪活动记录；kitchen_temp_sensor（温度传感器）读数始终在正常室温范围（约24-25°C），未出现火灾导致的急剧升温。因此，排除真实的火灾或燃气泄漏威胁。",
    "3. 关联其他传感器异常：在2026-08-13T06:52:00，kitchen_temp_sensor 报告 TemperatureMeasurement.MeasuredValue = None，随后恢复正常。这表明厨房区域的传感器网络可能存在通信不稳定或供电问题，进一步佐证了该区域电子设备存在整体性故障的可能性。",
    "4. 综合判断：ContaminationState 通常指示传感器内部积尘、老化或检测到非火源微粒。连续三天的固定时间触发，结合温度传感器的数据丢失，极大概率是烟雾报警器本身需要清洁、电池电量低或元件损坏导致的误报/故障，而非外部安全威胁。"

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。

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。

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。

  "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。

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. 排除真实威胁：尽管07-16早晨有灶具开启（cook_surface OnOff=True），但随后温度传感器读数平稳上升（从2469到2533，即24.69°C到25.33°C），并未出现火灾导致的急剧升温。更重要的是，07-17和07-18早晨并没有灶具开启的记录，但烟雾报警器依然触发了相同的污染状态。这种“无源触发”排除了真实烟雾的可能性。",
    "3. 确认设备故障：该事件在三天同一时间段重复发生，且状态值递增（1->2->3），符合传感器元件老化、积灰严重或内部电路故障的特征。由于没有住户活动（如长时间停留厨房）与报警完全同步，且其他环境参数正常，判定为传感器本身的维护需求或故障。"

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。
