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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [

  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在正常烹饪操作期间出现严重数据漂移/故障，读数瞬间异常飙升（2920），远超物理可能范围。",
  "reasoning": [
    "推理步骤 1: 分析时间线，在 2026-07-25T12:05:00 时，厨房灶具 (kitchen_cook_surface) 被开启 (OnOff = True)，随后几分钟内厨房温度传感器读数稳定在 2500-2540 之间（对应约 25°C），符合夏季室内环境特征。",
    "推理步骤 2: 在 2026-07-25T12:12:00，即灶具开启后约 7 分钟，厨房温度传感器报告 MeasuredValue = 2920。考虑到其他房间传感器读数均在 2500 左右，且该数值比前一刻高出近 400 单位，这在物理上是不可能的（意味着 292°C 或设备内部短路导致的溢出）。",
    "推理步骤 3: 尽管在 12:15:00 读数回落至正常范围 (2519)，但中间出现的极端跳变表明传感器硬件故障、通信干扰或固件逻辑错误。这种‘传感器漂移’可能导致基于此数据的自动化联动（如误触发烟雾报警或空调策略）失效，构成安全隐患。",
    "推理步骤 4: 结合上下文，虽然用户正在使用灶具，但温度读数并未随加热过程线性上升，而是出现断崖式突变，排除了真实火灾风险，确认为设备层面的故障。"
  ],
  "key_evidence": [
    "2026-07-25T12:05:00 kitchen_cook_surface OnOff.OnOff = True (开始烹饪)",

    "立即检查厨房温度传感器的物理连接和供电状态，排除接触不良。",
    "重置厨房温度传感器或重启其所在的 Matter 网关节点以清除临时故障。",
    "在修复前，暂时禁用依赖该传感器进行安全联动的自动化场景（如高温自动关火），并建议用户手动监控烹饪过程。",

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",

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。

## 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": [
    "建议措施1",

  ]
}
```

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。

  "confidence": "medium",
  "threat_type": "none",

    "推理步骤 3: 随后在 19:35:00，温度进一步升高至 27.4°C (2740 mK)，且尽管之后有下降趋势，但相比正常室温（约 22-23°C），该高温读数在灶具关闭后出现且伴随剧烈波动，不符合自然冷却规律，极可能是传感器漂移、被热源遮挡或存在未察觉的明火/过热风险。考虑到独居老人背景，此情况属于高风险。"
  ],
  "key_evidence": [
    "19:20:00 灶具关闭事件与 19:25:00 温度骤升事件的时间间隔过短且温差巨大。",
    "温度读数在灶具关闭后未能回归正常室温范围，反而出现非线性的剧烈波动。"
  ],
  "recommended_actions": [
    "立即远程通知住户检查厨房是否有明火、烟雾或异常气味。",
    "建议系统自动触发厨房烟雾报警器进行二次确认（如果逻辑允许）。",

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。
