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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

  "reasoning": [

  ]
}

  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在正常烹饪活动期间出现严重数据漂移和间歇性失效，导致无法准确监测潜在的火险或过热风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-07-28T18:02:00 至 18:15:00 期间，厨房温度传感器报告了异常高的数值（2840, 2810, 2960），随后在 18:18:00 和 18:56:00 返回 None。这些高数值远超正常室温范围（约 23°C，即 2300 mK），且与随后恢复正常的读数（~2300）形成剧烈反差。",
    "推理步骤 2: 结合上下文，18:17:00 厨房灯开启，表明有人进入厨房进行活动。虽然存在烹饪可能性，但温度从 ~2300 瞬间飙升至近 3000 并在短时间内回落，不符合常规烹饪产生的持续高温特征，更符合传感器故障导致的读数跳变。",
    "推理步骤 3: 该传感器的间歇性失效（返回 None）进一步证实了设备硬件或通信层面的问题。如果这是真实的火灾或极端高温事件，烟雾报警器应已触发，且温度不会在短时间内自行恢复正常。这种‘幽灵高温’现象是典型的传感器漂移或校准错误。"

  ],
  "recommended_actions": [
    "立即检查并重新校准厨房温度传感器，或将其暂时替换为备用传感器以确保安全监控不中断。",
    "检查厨房烟雾报警器和一氧化碳报警器是否正常工作，作为当前温度传感器失效期间的冗余安全措施。",

## 任务
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

请按以下 JSON 格式回答：

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：日志中多次出现 `kitchen_smoke_alarm` 的 `SmokeCoAlarm.ContaminationState` 属性变化。具体为：2026-07-01 08:00 值为 1，2026-07-02 08:00 值为 2，2026-07-03 08:00 值为 3。",
    "2. 分析数值含义：在 Matter/Smart Home 标准中，ContaminationState 通常用于指示传感器探测腔内的污染程度（如灰尘积累）。数值从 1 增加到 3 表示污染程度随时间加剧，或者设备处于不同的报警/维护阶段。这通常是维护提醒或传感器脏污的信号，而非烟雾浓度（SmokeConcentration）或火警状态。",
    "3. 排除真实火灾风险：检查同一时间段内的其他传感器数据。厨房温度传感器（kitchen_temp_sensor）显示温度在 24°C - 25.5°C 之间波动，属于正常室温范围，没有出现火灾导致的急剧升温。同时，没有触发 `SmokeCoAlarm.FireAlarm` 或 `SmokeCoAlarm.SmokeAlarm` 等紧急报警属性。",
    "4. 结合行为模式：住户日常活动规律（早晨开灯、出门锁门、卫生间使用等）正常，无异常入侵或长时间未活动的迹象。因此，该异常更倾向于硬件维护问题（传感器需要清洁或更换），而非即时安全威胁。"

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。

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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. 关键告警触发：日志显示在 03:16:00，kitchen_smoke_alarm 的 SmokeState 变为 1（报警状态），同时 living_room_smoke_alarm 的 InterconnectSmokeAlarm 变为 1，表明系统检测到烟雾并进行了联动报警。",
    "2. 温度异常趋势佐证：在烟雾报警前（02:20 - 03:15），厨房温度传感器读数从 2335 (23.35°C) 持续上升至 2361 (23.61°C)，客厅温度也从 2319 (23.19°C) 上升至 2376 (23.76°C)。虽然绝对值看似不高，但在凌晨时段（通常环境温度较低或稳定），这种跨房间的同步、持续性升温是火灾早期热释放的典型特征。",
    "3. 排除误报可能性：所有房间的运动传感器（occupancy_sensor）在报警前后均保持为 0，说明屋内无人活动。独居老人在凌晨无人为操作导致误触的可能性极低，且没有烹饪行为（unattended_cooking 通常指人离开但灶具开启，此处更倾向于突发火情）。",
    "4. 综合判断：烟雾报警与温度异常上升相结合，且发生在无人值守的深夜，极大概率为厨房发生了起火事件。"

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：

  "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。

    "2. 排除误报可能性：虽然此时段（凌晨3点）所有房间的 `OccupancySensing.Occupancy` 均为 0，表明家中无人，这排除了因烹饪疏忽导致的即时人为干预场景，但也意味着如果发生火灾，现场无人员可立即处置，风险等级极高。",
    "3. 环境数据辅助分析：虽然温度传感器读数（约23-24摄氏度）未显示急剧升温，但这可能是因为火灾处于初期阶段、烟雾先于高温被检测到，或者温度传感器位于远离起火点的客厅，未能及时反映厨房局部的剧烈温升。烟雾报警器的直接触发是更优先的安全信号。"

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。
