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": [
    "1. 识别关键异常事件：日志显示在 2026-07-25T08:00:00 和 2026-07-26T08:00:00，kitchen_smoke_alarm 的 SmokeCoAlarm.ContaminationState 分别变为 1 和 2。根据 Matter 标准，这通常表示传感器检测到灰尘、昆虫或其他污染物积聚，需要清洁或维护，而非火灾报警。",
    "2. 观察持续性模式：这种‘污染’状态在连续两天同一时间（早上8点）出现，排除了偶发性干扰（如偶尔的烹饪油烟），暗示设备内部可能存在持续的物理污染或传感器元件老化/故障。",
    "3. 确认设备失效风险：在 2026-07-27T07:10:00，kitchen_temp_sensor 的温度读数变为 None，紧接着在 08:00:00 烟雾报警器再次报告 ContaminationState = 3（通常代表更严重的故障或不可用状态）。虽然温度传感器变空可能独立，但结合烟雾报警器的持续报错，强烈暗示厨房区域的环境监测设备组存在系统性故障或通信问题。",
    "4. 排除其他威胁：日志中未检测到火灾特征（如温度急剧升高伴随烟雾报警触发）、入侵行为（门锁操作正常，无非法开启记录）或一氧化碳泄漏迹象。主要问题集中在安全设备本身的状态异常。"

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

  "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. 伴随温度异常升高：在烟雾报警前后，所有房间的温度传感器读数均呈现显著且持续的上升趋势。例如，客厅温度从 01:20 的 ~23.1°C 上升至 04:50 的 ~24.4°C；主卧、儿童房和厨房温度也同步上升，厨房温度最高达到 ~24.2°C。这种全屋性的缓慢升温通常不是正常夜间波动，而是可能由热源（如未熄灭的火源、电器故障）引起的环境变化。",
    "3. 排除误报可能性：虽然凌晨时段无人员活动（Occupancy 均为 0），但温度数据的单调递增趋势与烟雾报警时间高度吻合，增加了真实火情或过热风险的可能性，而非单纯的传感器瞬时误报。"

## 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。

  "threat_description": "厨房温度传感器在正常烹饪结束后出现严重数据漂移，报告了远超物理可能性的异常高温值（3050°C 和 3220°C），导致误报火灾风险。",
  "reasoning": [
    "步骤 1: 分析时间线，用户在 19:20 关闭了灶具 (kitchen_cook_surface OnOff=False)，随后在 19:48 启动洗碗机，表明厨房活动处于正常结束后的清洁阶段。",
    "步骤 2: 观察温度传感器 (kitchen_temp_sensor) 读数变化：在 19:20 关闭灶具后，温度从约 228-230 (单位推测为 0.1°C，即 22.8-23.0°C) 开始缓慢下降，符合热力学规律。",
    "步骤 3: 发现关键异常点：在 19:25:00 和 19:35:00，传感器突然跳变至 3050 和 3220。这些数值即使按 0.1°C 换算也高达 305°C 和 322°C，这在没有明火或极端故障的情况下是不可能的；若按原始整数理解，更是完全超出任何家用环境传感器的量程。",
    "步骤 4: 结合上下文排除真实火灾：此时用户正在使用洗碗机且家中有人（occupancy 传感器显示客厅、餐厅、儿童房有人），且没有伴随烟雾报警器触发或其他火灾特征事件，因此判定为传感器硬件故障或通信数据包损坏导致的读数漂移。"

    "2. 排除误报可能性：虽然凌晨 3 点独居老人通常处于睡眠状态，但烟雾报警是最高优先级的安全威胁。日志中未显示任何烹饪活动（如灶具开启）或人为触发的记录，且温度传感器读数在报警前后虽有波动（2350-2400范围，单位可能是0.01摄氏度即23.5-24.0°C），但并未出现急剧升温至危险高温的迹象，这可能意味着烟雾来源并非剧烈燃烧产生的高热，或者是早期阴燃阶段，亦或是传感器故障/误报。然而，基于安全第一原则，必须将其视为真实威胁处理。",
