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。

    "推理步骤 3: 排除误报可能性，该数值 (2960) 相对于之前的 23xx 系列读数发生了断崖式跳跃，不符合热力学规律，属于典型的传感器数据漂移、校准错误或通信丢包导致的乱码，而非真实火灾风险。"

## 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

  "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。

    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据（如客厅、卧室均在 22-23°C 之间波动），厨房传感器的读数不仅数值异常巨大，而且与其他环境数据完全脱节，不符合热力学规律（即使灶具开启，也不可能瞬间达到 300°C+）。",
    "推理步骤 3: 结合日志中多次出现的 `MeasuredValue = None` 现象，以及数值从正常范围（~23°C）直接跳跃到超量程值（>300°C）的特征，可以判定这不是真实的火灾风险，而是传感器硬件故障、校准失效或 Matter 协议传输过程中的严重数据损坏/漂移。"

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",
  "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": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房烟雾报警器连续三天在早晨固定时间报告污染状态（ContaminationState）持续恶化，且未伴随任何火灾或烹饪产生的烟雾/温度异常，判定为传感器硬件故障或严重误报。",
  "reasoning": [
    "1. 识别关键异常事件：日志显示厨房烟雾报警器（kitchen_smoke_alarm）在2026-08-05、08-06、08-07的早晨08:00分别报告了 ContaminationState = 1, 2, 3。根据Matter标准，这通常表示传感器检测到内部污染（如灰尘积累）或元件老化，导致灵敏度下降或失效风险增加。",
    "2. 排除真实火灾/烹饪威胁：尽管报警发生在早晨（通常是做饭时间），但厨房温度传感器（kitchen_temp_sensor）的数据始终维持在24°C-25°C左右（对应实际温度约24-25摄氏度，Matter协议中值为摄氏度*100）。如果存在真实的火灾或剧烈烹饪，温度会急剧上升，且通常会触发SmokeCoAlarm.AlarmState（火警/烟警），而不仅仅是ContaminationState。当前日志中无火警记录。",
    "3. 确认模式非正常行为：ContaminationState从1变为2再变为3，呈现明显的线性恶化趋势，且时间点高度一致（均为08:00）。这表明不是偶发的环境干扰，而是设备本身的持续性故障。由于烟雾报警器是安全关键设备，其“污染”状态意味着它可能无法在真正发生火灾时正确报警，构成安全隐患。"

    "[2026-08-07T08:00:00] kitchen_smoke_alarm | SmokeCoAlarm.ContaminationState = 3",
    "同期厨房温度传感器数值稳定在2480-2550之间（约24.8-25.5°C），无高温峰值，排除真实火灾。"
  ],
  "recommended_actions": [
    "立即检查并清洁厨房烟雾报警器，清除可能的灰尘或昆虫堵塞。",

    "推理步骤 2: 关键时间点 2026-08-05T08:00:00 和 2026-08-06T08:00:00，厨房烟雾报警器状态分别变为 ContaminationState=1 和 2，表明检测到烟雾或污染，这与高温趋势高度吻合，提示可能存在烹饪过热、设备故障或初期火灾。",
    "推理步骤 3: 结合 occupancy 日志，在温度飙升和报警触发的时间段（如 08:00 - 09:00），entrance_occupancy 多次显示为 0，且 master_bedroom_occupancy 也多为 0，表明住户不在场或未在厨房附近，属于典型的‘无人看管的高温/烟雾’高危场景。",

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
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：

```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": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房烟雾报警器触发，且客厅互联烟雾报警器同步报警，表明检测到火灾或烟雾风险。",
  "reasoning": [
    "1. 识别关键事件：日志显示在 2026-08-29T03:16:00，`kitchen_smoke_alarm` 的 `SmokeState` 变为 1（通常表示检测到烟雾/火警）。",
    "2. 验证联动机制：紧接着在 03:16:00 和 03:17:00，`living_room_smoke_alarm` 的 `InterconnectSmokeAlarm` 和 `ExpressedState` 均变为 1，这符合 Matter 协议中烟雾报警器互联报警的标准行为，确认了警报的真实性而非误报孤立事件。",
    "3. 排除正常干扰：虽然凌晨 03:00-04:00 期间所有房间的运动传感器均显示无人（Occupancy=0），但这符合深夜时段特征，不能排除厨房内发生突发火灾（如电器短路、遗留火源等）的可能性。",
    "4. 温度数据辅助分析：客厅温度传感器读数在 23°C 左右波动，属于正常室温范围，未出现急剧升温，这可能意味着火势尚处于初期阶段，或者烟雾探测器比温度传感器更敏感地捕捉到了早期信号。"
