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。

    "推理步骤 2: 对比卧室温度数据，同一时间段内卧室温度从 23.95°C 缓慢下降至 23.77°C，变化平稳且符合常理。这证明环境整体温度并未发生极端变化，进一步证实客厅传感器的异常是设备自身故障而非环境突变。",
    "推理步骤 3: 观察后续数据，13:55:00 时该传感器再次报告了两个截然不同的值 (24.79°C 和 26.10°C) 在同一秒内，这是典型的传感器硬件故障、校准错误或通信丢包导致的乱码现象，属于严重的 sensor_malfunction。"

    "2026-08-08T13:55:00 同一秒内连续上报两个不同温度值 (24.79°C 和 26.10°C)。",
    "同期卧室温度传感器数据显示正常缓慢降温趋势，排除了环境温度剧变的可能性。"
  ],
  "recommended_actions": [

## 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2"
  ],
  "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。

System:
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",
  "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。

Chosen response:

  "threat_description": "未检测到安全威胁或设备故障，日志显示为正常的家庭日常活动及洗衣机定时运行状态。",
  "reasoning": [
    "1. 分析重点设备（阳台洗衣机）：日志显示在 10:00 启动 (OperationalState=1)，随后在 10:20 和 10:40 出现 CountdownTime 递减事件（分别为 2400秒/40分钟 和 1200秒/20分钟），最后在 11:00 停止 (OperationalState=0)。这符合典型的洗衣机洗涤程序逻辑，无异常中断或卡死迹象。",
    "2. 分析入户门与玄关传感器：虽然日志中多次出现 entrance_occupancy = 1 且时间戳精确到 :39:21 或 :59:21 等固定偏移量，但这通常对应于住户进出家门时的正常行为模式（如开门、停留、关门）。结合 07:49 的 Manual Lock 操作，表明有人在家或刚回家，属于正常生活轨迹。",
    "3. 分析温度数据：各房间温度传感器数值在 2483-2557 (即 24.83°C - 25.57°C) 之间波动，变化平缓且符合夏季室内环境温度特征，未发现传感器漂移或故障导致的极端读数。",
    "4. 综合判断：所有设备状态变化均符合逻辑关联（如人进门-> occupancy 变1；洗衣机运行-> countdown 减少），未发现入侵、火灾、漏水或设备硬件故障的迹象。"
  ],
  "key_evidence": [
    "balcony_laundry_washer OperationalState 从 1 变为 0，中间伴随 CountdownTime 正常递减，证明设备完整执行了洗涤任务。",
    "entrance_occupancy 频繁触发但伴随 door_lock 手动操作及合理的居住者活动规律，排除非法入侵。",
    "全屋温度传感器读数稳定在舒适区间，无异常跳变。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",

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",

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",

  ],
  "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: 考虑到 Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以 0.1°C 为单位（即 2550 代表 25.50°C），该设备在短时间内无法提供稳定读数且与其他环境传感器数据严重背离，确认为传感器自身硬件故障或信号干扰导致的 malfunction，而非真实的环境突变。"

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。

    "推理步骤 1: 分析时间线发现，在 11:00 至 12:50 期间，厨房温度传感器读数异常飙升（从 2559 升至 2895），随后在 12:52 报告为 None（通信中断或故障）。",
    "推理步骤 2: 对比其他房间数据，此时主卧、次卧等区域温度稳定且符合室温逻辑，排除了全屋极端高温环境的可能性。",
    "推理步骤 3: 关键证据在于 13:00 客厅空调开启后，客厅温度迅速下降并恢复正常范围，而厨房温度在 13:15 再次出现剧烈波动（2840 -> 2720 -> 2610），这种与物理环境不符的剧烈震荡表明传感器本身存在硬件故障或校准失效，而非真实的高温事件。",
    "推理步骤 4: 由于厨房是火灾高发区，且烟雾报警器依赖准确的温度/环境数据作为辅助判断，该传感器的持续故障构成了潜在的安全隐患（fire_risk），但其根本原因是设备本身的 malfunction。"
