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",

  ],
  "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。

    "2. 温度数据分析：厨房温度传感器读数在 2469-2534 (单位通常为0.01摄氏度，即约24.7°C-25.3°C) 之间波动，变化平缓且处于舒适区间。其他房间温度也呈现正常的日间缓慢下降趋势（从~25°C降至~24.3°C），无异常骤升（火灾风险）或骤降（设备故障/极端天气）。",
    "3. 人员活动分析：所有运动传感器（Occupancy Sensor）在 13:00 至 15:00 期间均报告为 0（无人）。结合时间（下午13:00-15:00），这可能是家庭成员外出工作或休息的正常状态。虽然长时间无人可能触发安防警报，但在没有入侵迹象（如门锁异常、窗户打开）的情况下，仅凭无人状态不构成安全威胁。",
    "4. 综合判断：没有烟雾报警、漏水检测、门锁异常或一氧化碳报警等关键安全事件触发。设备逻辑连贯，环境参数稳定，判定为无异常。"

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。

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",
  "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",

}
```

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": "厨房温度传感器报告了异常高的数值（约 29.2°C），且该读数在设备开启后出现剧烈波动，随后迅速回落至正常范围，表明传感器可能发生故障或校准错误。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-08-04T12:12:00 时，kitchen_temp_sensor 报告的 MeasuredValue 为 2920。根据 Matter 协议及常见智能家居传感器的数据格式，这极有可能是 29.2°C 的浮点数被误报为整数，或者是传感器发生了严重的读数漂移/故障。",
    "推理步骤 2: 对比上下文，该异常读数发生在 kitchen_cook_surface (灶具) 于 12:05:00 开启之后。虽然烹饪会产生热量，但通常不会导致室温瞬间飙升至接近 30°C（除非是极端情况，但结合后续数据看可能性极低）。",
    "推理步骤 3: 关键证据在于读数的不稳定性。在 12:12:00 达到峰值 2920 后，仅过 3 分钟（12:15:00）读数就骤降至 2517，并在随后的几分钟内稳定在 2500-2540 之间。这种“尖峰”现象不符合物理热传导规律，强烈暗示传感器本身存在硬件故障、软件 bug 或通信干扰导致的瞬时错误上报，而非真实的火灾风险。",
    "推理步骤 4: 尽管存在读数异常，但其他安全指标（如烟雾报警器未触发、漏水传感器无报警、门窗传感器状态正常）均显示系统处于受控状态，因此主要威胁判定为传感器故障而非真实的安全入侵或火灾。"
  ],
  "key_evidence": [
    "2026-08-04T12:12:00 厨房温度传感器读数突增至 2920 (疑似 29.2°C)，远超正常室内环境。",

    "灶具开启时间 (12:05) 与温度峰值 (12:12) 间隔较短，且温度下降速度过快，不符合真实加热过程的热惯性。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理连接和电池状态，排除接触不良或电量不足问题。",
    "建议将厨房温度传感器标记为‘需维护’或暂时从自动化逻辑中移除，防止其错误数据触发空调或其他联动设备。",
    "联系设备制造商获取固件更新或技术支持，以修复可能的软件校准错误。"

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。

    "推理步骤 2: 关键异常点出现在 2026-08-14T19:25:00，厨房温度传感器读数从正常的约 23°C (2273mK) 瞬间跳变至 2860 (约 25.8°C) 和随后的 2740 (约 24.1°C)。虽然数值换算后看似不高，但在 Matter 协议中，TemperatureMeasurement.MeasuredValue 通常以毫开尔文 (mK) 为单位。若原始数据单位理解偏差或设备故障导致读数逻辑错误，需警惕；更可能的情况是，结合上下文，这是设备试图报警前的异常波动，或者用户误操作导致高温区域未被及时关闭。",

    "最终确认：灶具开启后，人员在多房间活动，存在‘离人烹饪’风险。随后温度读数出现非自然的剧烈跳变，极可能是火灾前兆或传感器因高温触发的保护性异常读数。"

## 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",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "检测到厨房烟雾报警器正在进行正常的自检程序，无火灾或设备故障风险。",
  "reasoning": [
    "1. 分析重点设备日志：在 2026-08-20T08:00:00 至 08:05:00 期间，kitchen_smoke_alarm 的 SmokeCoAlarm.TestInProgress 属性从 True 变为 False。这明确表明设备正在执行内置的自我测试功能（Self-test），这是智能家居安全设备的标准维护行为，用于验证传感器和报警电路是否正常工作。",
    "2. 排除真实火警：如果发生真实火灾，SmokeCoAlarm 通常会报告 AlarmState (如 Fire Detected) 或触发声光报警事件，而不是 TestInProgress 状态。此外，同一时间段内 kitchen_temp_sensor 的温度读数在 2536-2540 (即 25.36°C - 25.40°C) 之间波动，处于正常室温范围，没有急剧升温迹象，排除了高温导致的误报或真实火情。",
    "3. 检查关联环境数据：日志显示 ContaminationState = 0，表示传感器未检测到灰尘污染，进一步佐证了设备状态良好。同时，其他房间（客厅、卧室）的运动传感器均显示 Occupancy = 0，说明此时家中无人，符合进行设备自检或日常待机时的场景特征。",
    "4. 综合判断：结合温度稳定、无火警状态码、以及明确的 TestInProgress 标志，判定该事件为正常的设备自检活动，不存在安全威胁。"

    "Kitchen temperature remained stable around 25.4°C during the test period."
  ],
