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
请从下面的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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: ..."
  ],

    "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:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "多个窗户传感器短时依次触发",
  "reasoning": [
    "推理步骤1: 短时间内两个不同房间窗户先后打开",
    "推理步骤2: 触发时间位于深夜",
    "推理步骤3: 随后出现室内运动"
  ],

  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器在夜间无人状态下出现持续且异常的数值漂移，读数远超正常环境温度范围，疑似传感器故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 分析时间线与 occupancy 状态。日志显示从 00:00 到 04:00，living_room_occupancy 持续为 0（无人），直到 02:34 才短暂变为 1，随后在 03:00、03:30、04:00 又变回 0。这表明该时间段内住户主要处于睡眠或外出状态，室内应无热源活动。",
    "推理步骤 2: 检查温度数据合理性。Matter 协议中温度通常以 0.01°C 为单位存储。日志中 living_room_temp_sensor 的 MeasuredValue 从 00:55 的 2285 (约 22.85°C) 开始，一路攀升至 04:05 的 2408 (约 24.08°C)，并在后续未有人活动的情况下继续波动上升。虽然 22-24°C 看似正常，但结合上下文需进一步验证。",
    "推理步骤 3: 对比其他房间与物理常识。卧室和厨房的温度读数相对稳定（卧室约 22.2-22.7°C，厨房约 23.2-23.7°C）。然而，更关键的异常在于：如果这是真实的温度变化，在无人的深夜，室温通常会因散热而缓慢下降或保持恒定，而不是在没有明显加热设备开启（如空调日志未显示开启动作）的情况下呈现这种不规则的锯齿状上升趋势。此外，若将数值解读为毫摄氏度，2400mC = 24.00°C 是合理的，但考虑到 Matter 设备的常见漂移问题，以及缺乏对应的 HVAC 控制指令（actuator_stuck 或 air_conditioner 状态变更），单纯的数值持续非自然波动更符合 sensor_drift 的特征。特别是 02:34 有人进入后温度并未发生剧烈突变，反而继续随时间推移有微小爬升，这不符合人体热辐射导致的瞬间升温特征，更像是传感器内部基准漂移。",
    "推理步骤 4: 综合判断。在长时间无人监控下，单一传感器出现持续的非线性、无对应执行器动作支持的数值漂移，属于典型的 sensor_drift 风险，可能导致误报火灾或错误的自动化触发。"
  ],
  "key_evidence": [
    "在 00:00 至 04:00 期间，living_room_occupancy 多次报告为 0（无人），但温度读数却呈现持续的非自然波动和爬升趋势。",
    "温度变化缺乏对应的 actuator（如空调或加热器）状态变更记录作为支撑，且变化模式不符合人体存在时的热力学特征。"
  ],
  "recommended_actions": [
    "立即标记 living_room_temp_sensor 为“需要维护/校准”状态，并在本地逻辑中暂时忽略其读数以避免误触发警报。",
    "通知用户检查客厅温度传感器的电池电量及安装位置，建议进行硬件重置或更换传感器。"

    "4. 排除误报：虽然白天也有 occupancy 变化，但凌晨时段的“开门-亮灯-人员出现”这一序列非常符合入侵者进入住宅的行为模式。此外，02:30 所有房间 occupancy 归零，可能是入侵者离开或系统重置，但之前的活跃已构成威胁证据。"

## 任务
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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。

    "推理步骤1: 连续 3 天都在 03:14 出现客厅运动",
    "推理步骤2: 时间点高度一致",
    "推理步骤3: 第 3 天继续延伸到厨房活动"

    "推理步骤 2: 观察日志中 living_room_temp_sensor 的数据变化，在无人状态下，温度值从正常的 23.12°C (2312 mK) 开始，呈现线性上升趋势，最高达到 24.42°C (2442 mK)，并在随后几天重复此模式。",
    "推理步骤 3: 对比厨房和卧室的温度数据，厨房温度虽有波动但相对平稳（约 23.4°C - 24.1°C），卧室温度稳定在 22.4°C - 22.9°C 之间，均符合夜间散热规律。唯独客厅温度在无热源（如空调、人员）介入的情况下异常升高，且升温速率不符合自然热力学规律，排除了真实环境升温的可能性，判定为传感器读数漂移或硬件故障。"

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。

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。

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。
