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。

系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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",

## 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",

    "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": "intrusion",

    "推理步骤3: 随后出现室内运动"
  ],

  "threat_description": "凌晨时段（02:31-04:10）客厅窗户被打开，且室内温度持续异常升高至近 25°C，而住户处于无活动状态，存在极高的火灾或高温安全隐患。",
  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示在 2026-08-02 凌晨 02:31 分，living_room_window_contact 状态变为 False（窗户打开）。此时为深夜，独居老人通常已入睡，且后续日志显示 living_room_occupancy 在 02:34 之前一直为 0，表明屋内无人。",
    "推理步骤 2: 温度异常趋势分析。从 02:31 窗户打开开始，客厅温度传感器读数呈现明显的上升趋势：从 02:35 的 23.48°C (2348mK) 一路攀升，到 04:00 达到 23.97°C (2397mK)，并在 04:05 达到峰值 24.13°C (2413mK)。这种在无人员活动的情况下，夜间室温显著高于正常睡眠环境（通常应低于 22°C）且持续上升的模式非常可疑。",
    "推理步骤 3: 排除正常行为与综合判断。虽然夏季夜晚开窗可能导致热量进入，但考虑到是独居老人，且温度在短时间内（约 1.5 小时）上升了接近 1°C 并维持在高位，结合窗户在凌晨非正常开启的时间点，最合理的解释是发生了外部火源引燃（如窗外杂物起火、线路短路等），导致热空气涌入或烟雾/热气积聚，或者窗户被非法入侵者打开以进行破坏/盗窃前的试探。对于独居老人而言，这是最高级别的安全威胁。"

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。

  "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。"

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。

  "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",

## 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",
  "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": "intrusion",
  "threat_description": "连续多天同一时段出现陌生运动模式",
  "reasoning": [
    "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"
  ],
  "key_evidence": [

  "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升温漂移，数值远超正常环境温度范围，疑似设备故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 分析跨天活动摘要，发现 2026-08-27 至 2026-08-29 的凌晨时段（约 01:40 - 04:50），living_room_occupancy 状态长期为 0（无人），表明此时段应为住户睡眠或离家后的静默期。",
    "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。"

    "同一时间段内，living_room_temp_sensor 读数从 2312 持续上升至 2442，而同期 bedroom_temp_sensor 保持在 2240-2294 的稳定区间。",
    "该异常模式在三天日志中高度一致地重复出现，具有明显的周期性特征，非随机干扰。"
  ],
  "recommended_actions": [
    "立即检查客厅温度传感器的物理连接及供电情况，排除接触不良导致的误报。",
    "使用独立温度计测量客厅实际环境温度，验证传感器读数是否准确。",
    "若确认传感器故障，建议更换设备或在智能家居系统中暂时禁用该传感器数据，防止基于错误数据的自动化逻辑（如误开空调）触发。"
