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
以下是过去 2 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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。

    "推理步骤 2: 结合独居老人背景，长时间无人看管使用明火/电热灶具是典型的火灾隐患。虽然厨房运动传感器显示有人 (Occupancy=1)，但考虑到老人可能行动缓慢或专注于烹饪而忘记离开，这种‘人在场但注意力不集中’的状态极易引发事故。",
    "推理步骤 3: 温度传感器数据显示，在灶具开启期间，厨房温度从正常的室温范围迅速攀升至 2540K (约 2267°C) 的数值（注：此处原始数据单位极可能是毫开尔文 mK 或存在传感器校准漂移，但相对趋势显示温度持续高位运行），远高于正常烹饪时的环境温度，进一步佐证了热源持续工作的状态。",
    "推理步骤 4: 对比 2026-07-13 的记录，虽然也有开启行为，但 12:00 开启后在 12:04 即关闭，时长仅 4 分钟，属于正常操作；而 7 月 12 日的长时开启模式构成了显著的安全威胁。"

    "同一日期 12:00:00 再次开启灶具，日志中无后续关闭事件，暗示设备可能处于持续加热状态。",
    "独居老人作为住户，缺乏即时干预能力，增加了长时烹饪的风险等级。"
  ],
  "recommended_actions": [
    "立即远程切断厨房灶具电源，防止过热起火。",
    "检查厨房烟雾报警器 (smoke_co_alarm) 是否正常工作，并确认是否有误报或真实火情。",
    "联系住户或其紧急联系人，告知异常情况并询问家中安全状况。",
    "建议为老人安装智能插座或带有自动断电功能的燃气/电磁炉控制器，设定最大烹饪时长限制。"

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

Chosen response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "老人连续多天活动范围缩小",
  "reasoning": [

Rejected response:
```json

  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式正常，无入侵、火灾或设备故障迹象。",
  "reasoning": [
    "入住与离开时间规律：老人通常在早上 7:00-8:30 之间起床并出门（门锁操作），晚上未出现异常长时间滞留或深夜频繁出入，符合独居老人的常规作息。",
    "多房间联动逻辑正常：当卧室检测到有人时，厨房和客厅随后也检测到活动，且温度传感器读数随人体进入房间而自然上升（例如从 24°C 升至 25.5°C），这是正常的热效应，非设备故障。",
    "安全设备状态良好：烟雾报警器、漏水传感器等关键安全设备在日志中未触发报警事件，且门窗接触传感器仅在人员进出时正常翻转，未发现非法入侵或窗户被强行打开的迹象。",
    "数据一致性高：所有温度值均在合理范围内（约 21°C-26°C），运动传感器无长时间误报或死锁现象，跨天数据摘要显示活动量稳定，未见异常波动。"
  ],
  "key_evidence": [
    "2026-08-11T08:30:00 至 08:30:02 的入户门锁解锁及门磁状态变化，表明是受控的正常开门行为。",
    "各房间温度传感器读数随 occupancy=1 出现小幅上升，符合物理规律，排除了传感器漂移或故障。",
    "连续三天（8/11-8/13）的活动计数和事件序列高度一致，显示出稳定的生活习惯。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期检查电池供电的无线传感器电量，确保长期运行稳定。",
    "可考虑为老人设置简单的健康关怀提醒（如连续 12 小时无活动则通知家属），作为预防性措施。"
  ]
}

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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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",

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
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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",

  ]
}
```

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。

    "空间逻辑一致性：运动传感器（Occupancy）与灯光/电器状态高度吻合。例如，厨房灯开启时厨房有人，离开后关闭；卧室窗帘在下午打开且温度下降，符合自然光照和降温逻辑。未见‘无人却开灯’或‘有人却关灯’等矛盾行为。",
    "环境数据合理性：温度传感器读数（如客厅 25°C 左右，卧室 23-24°C）处于舒适居住范围，且随昼夜变化有合理波动；未出现烟雾报警器触发、漏水报警或门锁异常解锁等安全威胁信号。",
    "跨天模式稳定：三天内的活动频率和房间使用顺序（早晨厨房->客厅->卧室->傍晚厨房）保持一致，表明这是该住户的稳定习惯，而非突发异常行为。"
  ],
  "key_evidence": [
    "厨房灶具 (cook_surface) 仅在白天有人活动时短暂开启并随后关闭，无长时间无人烹饪记录。",
    "所有窗户传感器 (contact_sensor) 和门传感器 (contact_sensor) 均未报告非法开启或意外位移事件。",
    "温度传感器数值连续且平滑，无突变或超出物理极限的漂移现象。"
  ],

    "建议定期（如每周）人工复核一次烟雾报警器和漏水传感器的电池及功能状态，作为预防性维护。"

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
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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。

Rejected response:

    "环境数据合理：温度传感器读数（如 25.2°C - 25.6°C）处于舒适且安全的范围内，烟雾报警器未触发报警，漏水传感器无异常报告，排除了火灾和漏水风险。",
    " occupancy 逻辑自洽：各房间的人员占用状态变化连贯，例如进入厨房前有玄关感应，离开后有相应的时间间隔，未发现传感器卡死或逻辑冲突导致的误报。"
