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: ...",

    "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。"

    "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。"

    "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",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

    "推理步骤2: ...",

    "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。

{

  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "电器运行时间异常长",
  "reasoning": [
    "推理步骤1: 设备持续运行超过常规时长",

    "推理步骤3: 存在过热或故障风险"
  ],

    "设备持续运行超过常规时长",
    "倒计时未按预期减少",

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "这些变化仍可视为正常波动。",
  "reasoning": [

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",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",

    "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_description": "厨房烟雾报警器触发，且客厅互联烟雾报警同步响应，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），紧接着 `living_room_smoke_alarm` 的 `InterconnectSmokeAlarm` 也变为 1，确认了跨设备联动报警。",
    "2. 排除误报可能性：虽然凌晨3点独居老人可能未活动（所有房间 occupancy 均为 0），但温度传感器数据显示客厅温度从 02:00 的 ~23.2°C 缓慢上升至 04:45 的 ~24.2°C。这种升温幅度较小且平缓，不符合典型快速燃烧导致的剧烈温升，但也无法完全排除阴燃初期或传感器漂移。然而，烟雾报警器的直接触发是最高优先级的安全信号。",
    "3. 结合住户情况评估风险：住户为独居老人，且在报警发生时所有区域均无人员活动迹象（Occupancy=0）。这意味着如果发生火灾，老人可能处于熟睡状态未能及时察觉，或者因健康原因无法行动，存在极高的生命安全风险。"

  ],
  "recommended_actions": [
    "立即通过智能家居平台或电话通知紧急联系人及物业，确认住户安全状况。",
    "远程检查厨房摄像头（如有）或联系现场救援人员排查火灾隐患，切勿仅依赖温度数据判断。",
    "事后需对烟雾报警器进行电池更换或设备自检，以排除设备故障导致的误报。"

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",
  "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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "电器运行时间异常长",
  "reasoning": [
    "推理步骤1: 设备持续运行超过常规时长",
    "推理步骤2: 倒计时未按预期减少",
    "推理步骤3: 存在过热或故障风险"
  ],
  "key_evidence": [
    "设备持续运行超过常规时长",
    "倒计时未按预期减少",
    "存在过热或故障风险"
  ],
  "recommended_actions": [
    "标记为设备异常长运行，建议停机检查。"
  ]
}

```json

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "家庭环境状态正常，设备运行符合预期，未发现安全威胁或异常行为。",
  "reasoning": [
    "温度数据合理性分析：厨房温度传感器读数（如 2534）代表 25.34°C，客厅及儿童房温度在 23-25°C 之间波动，符合夏季室内正常环境温度范围，无过热或冻结迹象。",
    "设备状态逻辑验证：洗碗机（kitchen_dishwasher）在 14:00 启动，随后 CountdownTime 从 5400 秒递减至 5200 秒，表明设备正在正常运行中，未出现卡死或故障。",
    "人员活动模式匹配：入户门、玄关、餐厅、儿童房等区域的运动传感器频繁触发（Occupancy=1），且时间分布均匀，与跨天摘要中显示的高频活动量一致，表明住户在家中有正常的日常活动，无长时间无人看管或异常入侵迹象。"

  "key_evidence": [
    "kitchen_temp_sensor 读数稳定在 23.5°C - 25.3°C 区间，无极端值。",
    "kitchen_dishwasher OperationalState.CountdownTime 持续递减，证明设备工作正常。",
    "entrance_occupancy 和 kids_room_occupancy 在多个时间点检测到有人，确认住户在场。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期清洁洗碗机滤网以确保长期高效运行。"
