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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

    "紧接着在14:07:00，读数恢复为24.76°C，与前后文及其他房间（如儿童房、主卧）的温度趋势（缓慢下降）基本一致，说明并非整个家庭环境突然降温，而是单一传感器的瞬时故障。",
    "虽然14:00有一个2430的读数，但结合14:05的-500和14:07的2476，这种剧烈的非连续性跳变进一步证实了传感器状态的不稳定。"

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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",

    "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。

    "设备运行正常：阳台洗衣机在 10:00 启动（OperationalState=1），并在后续时间点多次报告倒计时为 2400 秒（40 分钟），表明设备正在按计划运行，未出现卡死或状态丢失。",
    "传感器数据合理：所有温度传感器读数均在 25°C 左右（如 2510-2556 mK，即约 25.1-25.6°C），波动范围符合室内空调调节下的正常昼夜变化； occupancy 传感器在各房间的活动模式（如主卧、儿童房频繁有人，客厅偶尔无人）符合早晨起床、洗漱、用餐及家务活动的正常作息规律。",
    "无安全威胁信号：未检测到烟雾报警、漏水报警触发，窗户传感器无异常开启记录，且无长时间无人但门窗开启的异常情况。"
  ],
  "key_evidence": [
    "front_door_lock 在 07:39:22 和 07:39:27 之间快速切换 LockState (1->2)，符合正常进出行为。",

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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",

    "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。

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
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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。

}

```json

    " occupancy 与行为逻辑一致性：入户门接触传感器在 17:56 变为 False（开门），随后玄关、客厅等区域运动传感器陆续检测到人员活动（Occupancy=1），并在 19:39 餐厅灯关闭、20:10 客厅主灯调暗/关闭，完全符合住户回家后的正常生活轨迹和设备联动逻辑。",
    "关键安全设备状态正常：厨房烟雾报警器、漏水传感器、门锁等设备在日志中未报告异常状态变化（如触发报警或锁具故障），所有动作均响应于正常的人员活动。"
  ],
  "key_evidence": [
    "living_room_temp_sensor 温度从 24.77°C 平稳降至 22.5°C，符合物理规律。",
    "front_door_contact 状态变化与后续多个房间 occupancy 检测到的活动序列高度吻合，表明是合法住户进入。",
    "dining_room_light 和 living_room_light_1 的关闭/调光操作发生在有人活动的时段，属于正常的节能或休息行为。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持对温度传感器的定期校准检查，以确保长期数据的准确性。"

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

  "confidence": "medium",
  "threat_type": "actuator_stuck",
  "threat_description": "灯的 OnOff 与 Level 矛盾",
  "reasoning": [

    "推理步骤3: 更像执行/上报故障"
  ],

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 living_room_light_1 状态正常，无安全威胁或异常行为。",
  "reasoning": [
    "推理步骤 1: 分析温度传感器数据，客厅温度从 24.6°C (2462mK) 逐渐下降至约 22.4°C (2240mK)，符合傍晚至夜间自然降温规律，且与其他房间（厨房、主卧、儿童房）的温度变化趋势一致，表明环境感知正常。",
    "推理步骤 2: 检查占用传感器日志，虽然客厅在 15:00-20:10 期间显示无人 (Occupancy=0)，但这与随后其他房间（餐厅、儿童房、次卧等）陆续报告无人状态的时间线吻合，符合住户下班回家前离开客厅的正常生活模式。",
    "推理步骤 3: 针对目标设备 living_room_light_1，日志显示其在 20:10 被设置为关闭 (OnOff=False) 并设定亮度为 180 (可能是调光前的最后状态或误报的中间态，但随即在 20:12 再次确认关闭)。考虑到此时已是晚上 8 点且全屋大部分区域已无人，灯光关闭是预期的节能和安全操作，不存在设备卡死或异常开启的情况。"
  ],
  "key_evidence": [
    "living_room_temp_sensor 数据显示连续数小时温度平稳下降，符合物理规律。",
    "multiple occupancy sensors (dining_room, kids_room, second_bedroom, entrance) 在晚间时段同步报告无人，佐证了家庭活动结束的背景。",
    "living_room_light_1 在晚间无人时段执行了关闭操作，行为逻辑合理。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续监控后续日志，确保温度传感器读数稳定，无剧烈波动。"

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。

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。
