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",

  ],

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: 关键异常发生在 2026-08-16T19:20:00，此时灶具状态变为关闭 (False)，但紧接着在 19:25:00 温度读数突然从 2293 跳变至 3050 (约 30.5°C)，并在 19:35:00 进一步跳变至 3220 (约 32.2°C)。",
    "推理步骤 3: 考虑到其他房间（客厅、卧室）的温度读数稳定在 22-23°C 之间，且厨房未报告烟雾报警，这种瞬间的剧烈数值飙升不符合热力学规律，极大概率是传感器硬件故障、信号干扰或固件 Bug 导致的读数漂移/卡死，而非真实的火灾风险。"

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。

    "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。"

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

  "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
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。

{
  "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": [

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭日常活动模式，无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 2536）代表 25.36°C，符合夏季午后室内正常室温范围；其他房间温度在 23-25°C 之间波动，且随时间推移呈现自然的昼夜降温趋势，无设备故障导致的漂移或卡死现象。",
    " occupancy 与人员活动逻辑一致：入户门（entrance）运动传感器频繁触发（13:03, 13:23, 14:03 等），对应客厅和次卧的短暂占用信号，随后又变为无人状态，符合家庭成员进出及在不同房间活动的正常规律。",
    " 洗碗机运行状态正常：洗碗机在 14:00 启动（OperationalState=1），并在 15:00 报告倒计时 5400 秒（90 分钟），后续在 17:05 更新为 5200 秒，倒计时递减符合设备正常运行逻辑，未出现异常停机或超时。",
    " 跨设备关联验证：当主卧室（master_bedroom）检测到有人时，其温度传感器有相应读数，且与其他房间的无人状态形成合理的时间差分布，未发现传感器不同步或逻辑冲突。"
  ],
  "key_evidence": [
    "厨房温度从 25.36°C 逐渐下降至 23.74°C 左右，符合自然散热规律。",
    "入户门运动传感器多次触发后，系统正确识别了人员在玄关、客厅及主卧的活动轨迹。",
    "洗碗机倒计时从 5400 秒稳定减少至 5200 秒，表明设备正在按计划运行。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议继续保持对关键区域（如厨房烟雾报警器和漏水传感器）的定期监控。"
  ]
}

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": "厨房烟雾报警器触发，且客厅烟雾报警器联动报警，表明厨房区域可能存在火灾或严重烟雾风险。",
  "reasoning": [
    "1. 核心事件识别：日志显示在 2026-07-07T03:16:00，`kitchen_smoke_alarm` 的 `SmokeState` 变为 1（报警状态）。紧接着在 03:16:00 和 03:17:00，`living_room_smoke_alarm` 的 `InterconnectSmokeAlarm` 和 `ExpressedState` 也变为 1。这符合 Matter 协议中烟雾报警器互联（Interconnect）的标准行为，即一个探测器报警，其他联网探测器同步报警。",
    "2. 排除误报可能性：虽然凌晨 3 点通常是睡眠时段，但所有房间的运动传感器（occupancy_sensor）在该时间段均显示为 0（无人），说明住户正在睡觉，未对警报做出反应。然而，温度数据并未显示出极端的、瞬间的升温（例如从 23°C 瞬间升至 50°C+），而是呈现缓慢波动（厨房温度从 ~2330 缓慢上升至 ~2384 等，注意单位可能是 0.01度 Celsius，即 23.3°C - 23.8°C，属于正常室温范围）。这表明可能并非明火大火，而是烹饪残留烟雾、蒸汽积聚或设备故障导致的报警，或者是真实的早期火灾迹象（如电线过热产生的微量烟雾）。鉴于烟雾报警器的敏感性，必须视为真实威胁处理。",
    "3. 风险评估：独居老人在深夜睡眠中对烟雾警报不敏感，若发生真实火情，逃生时间窗口极短。即使是由烹饪残留物引起的假阳性，也反映了厨房环境存在潜在隐患（如油污堆积、通风不良或电器老化）。"

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。
