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。

Chosen response:

{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "设备工作状态正常，日志显示为典型的晚间回家、烹饪及休息前的日常行为模式，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. **入户与活动轨迹分析**：18:06 门锁手动解锁（Manual），随后客厅 occupancy 传感器检测到有人（Occupancy=1），且空调开启。这符合用户下班回家的典型行为逻辑，无非法入侵迹象。",
    "2. **烹饪行为分析**：18:54 灶具开启，19:29 厨房窗户打开（可能是为了通风排烟），随后温度传感器读数在烹饪期间有波动但随后趋于稳定。整个过程伴随人员活动（客厅 occupancy 持续为 1），属于正常的无人值守风险较低的场景（人在家附近）。",
    "3. **卧室灯光异常解释**：虽然任务重点提及 bedroom_light，但在 20:10 该灯亮起并调光至 180，随后在 20:18 调暗至 30。结合此时段卧室 occupancy 为 0（可能因传感器盲区或人刚离开/未进入检测区），以及客厅仍有人员活动，这更可能是用户在睡前准备阶段调整卧室氛围灯，或者是自动化场景触发，而非故障。即使无人，短时间开灯后调暗也是常见操作，不构成 'sensor_stuck' 或 'actuator_stuck' 的长期故障特征。",
    "4. **传感器数据合理性**：各房间温度传感器读数随时间缓慢变化，符合物理规律（如夜间散热、烹饪加热等），未见跳变或停滞导致的 'sensor_drift' 或 'sensor_malfunction'。"

## 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",
  "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": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本窗户/窗帘状态变化一致；异常样本存在重复矛盾读数。"
  ],
  "key_evidence": [
    "正常样本窗户/窗帘状态变化一致；异常样本存在重复矛盾读数。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房温度异常升高且伴随灶具开启，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-07-05T11:02:30 厨房灶具 (cook_surface) 被手动开启后，厨房温度传感器读数迅速攀升。",
    "推理步骤 2: 从 11:02 到 11:40（约 38 分钟内），厨房温度从 2539 (°C*100) 持续上升至 2549 (°C*100)，即 25.39°C 升至 25.49°C。虽然绝对温差不大，但结合独居老人背景，需关注设备状态。",
    "推理步骤 3: 关键异常点在于 2026-07-05T11:35:00，厨房温度传感器报告值为 None（数据丢失/通信中断）。在烹饪过程中传感器突然失效或停止上报，可能导致烟雾报警器无法联动或用户失去对高温环境的感知，构成安全隐患。此外，日志中未出现任何关闭灶具的操作记录，若烹饪结束未及时关闭，长期加热也可能导致过热。",
    "推理步骤 4: 考虑到住户为独居老人，对突发状况反应可能较慢，传感器数据丢失 (None) 意味着安全监控链路的断裂，属于高风险事件。"
  ],
  "key_evidence": [

  ],
  "recommended_actions": [
    "立即远程检查厨房物理环境，确认是否有明火、烟雾或食物烧焦情况。",
    "通知住户或紧急联系人前往厨房检查，并确认灶具是否已关闭。",
    "检查厨房温度传感器和烟雾报警器的连接状态及电池电量，排除硬件故障。",
    "建议设置自动化规则：当灶具开启超过一定时间（如 30 分钟）且无人操作时，自动发送警报给监护人。"

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。

  "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",

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
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。

    "推理步骤 3: 在数据丢失之后（18:45 起），传感器恢复上报的数据（如 2297, 2295）虽然数值上看起来合理，但考虑到之前的高温状态和可能的断电/重启，这种非连续的数据流表明传感器存在间歇性故障或校准漂移风险，无法保证当前时刻的安全监测准确性。"

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。

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。

  "threat_description": "卧室温度传感器读数出现严重逻辑错误，数值在正常范围与无效高温之间剧烈跳变，且伴随设备状态异常（如短时间内重复上报或数值突变），表明传感器可能故障或被干扰。",
  "reasoning": [
    "推理步骤 1: 分析卧室温度传感器 (bedroom_temp_sensor) 的数据流，发现从 14:00:00 开始，传感器报告了两次截然不同的数值：第一次为 2379 (约 23.8°C)，紧接着在 14:05:00 突然跳变为 2550 (约 25.5°C)。虽然温差看似不大，但结合后续数据看，该传感器在 14:00-14:05 期间存在明显的非连续性跳跃。",
    "推理步骤 2: 更严重的异常发生在 14:00:00 到 14:05:00 之间的数据点。日志显示 `2026-08-26T14:00:00` 报出 2379，随后 `2026-08-26T14:05:00` 报出 2550。然而，仔细观察 14:00:00 的条目，它实际上包含了两个不同的值（可能是日志解析错误或传感器瞬间双报）：先报 2379，后报 2430。紧接着 14:05:00 报 2550，而厨房温度在同一时间仅为 2471。卧室温度突然比厨房高出近 8 度，这在无热源介入的情况下极不合理。",
    "推理步骤 3: 关键证据在于 14:00:00 和 14:05:00 的时间戳与数值的对应关系混乱。特别是 14:00:00 这一时刻出现了两个不同温度值（2379 和 2430），这通常意味着传感器通信协议层出现乱序、重传错误，或者传感器硬件本身发生了瞬时死锁/复位导致的读数崩塌。此外，整个下午卧室温度持续下降至 2200 左右，而厨房温度稳定在 2400 左右，两者温差过大且卧室降温速率不符合物理规律（除非空调开启，但日志中未显示卧室空调开启记录，仅显示客厅空调在 18:20 开启）。这种数据的不一致性和突发性跳变符合传感器故障的特征。",
    "推理步骤 4: 排除入侵风险。虽然温度异常，但卧室运动传感器 (bedroom_occupancy) 在 14:01:50 明确报告无人 (Occupancy = 0)，且之后一直无人。因此温度异常并非由人员活动引起，进一步证实是传感器自身问题。"
