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 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。

  "threat_description": "出门频率突然下降",
  "reasoning": [

  ]
}

Rejected response:
```json
{

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式稳定，出入时间规律，设备状态与人员活动逻辑一致，未发现安全威胁。",
  "reasoning": [
    "入住与出门行为逻辑正常：日志中入户门锁操作（LockOperation）均紧随玄关运动传感器检测到有人进入之后，且门接触传感器（front_door_contact）在开门后正确变为 False，随后门锁状态（LockState）变为锁定（2），符合老人起床洗漱、准备出门的正常流程。",
    "跨天活动模式高度一致：对比三天数据，卧室 occupancy 在早晨 07:26 左右开始活跃，客厅温度在 08:35-09:40 之间随人员活动逐渐升高并稳定在 25.4°C 左右，厨房和卫生间的使用频率也保持平稳，未见异常的时间偏移或活动缺失。",
    "环境参数与人员分布匹配：温度传感器读数随人员在不同房间的活动而动态变化（如离开房间后温度缓慢回落或稳定），未出现传感器漂移或故障导致的恒定异常值；烟雾报警器和漏水传感器未触发告警，结合正常的用水和烹饪记录，排除了火灾和漏水风险。"
  ],
  "key_evidence": [
    "2026-08-09T08:28:00 至 09:01:00 期间，门锁操作、门接触状态变化及后续锁定动作时序连贯，无非法入侵迹象。",
    "连续三天的卧室 occupancy 激活时间（约 07:26）和离开时间（夜间 23:50 左右）保持高度一致，表明住户作息规律。",
    "所有温度传感器读数均在合理范围内（24.3°C - 25.6°C），且随人员移动呈现合理的空间温差分布，无传感器故障特征。"
  ],
  "recommended_actions": [

## 任务
以下是过去一段时间的设备活动记录。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": [

    "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。

Rejected response:

  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:15，此时独居老人通常处于睡眠状态（卧室和客厅运动传感器长期为 0），属于非活跃时段。",
    "推理步骤 2: 占用与设备状态矛盾。从 02:10 开始，厨房运动传感器 (kitchen_occupancy) 检测到有人 (Occupancy=1)，但随后在 02:30、03:00、03:30、04:00 等多次报告中显示厨房无人 (Occupancy=0)。这种‘幽灵占用’或间歇性检测到的现象，结合后续温度急剧上升，极可能是传感器误报或干扰，而非真实人员活动。",
    "推理步骤 3: 温度异常趋势。厨房温度传感器读数从 02:10 的约 23.2°C (2321 mK) 持续攀升，至 04:15 达到 24.17°C (2417 mK)。对于夜间无人（或疑似无人）的厨房，近两小时内升温超过 1 度且无降温迹象，符合灶具未关闭或电器故障导致的热量积聚特征。考虑到 Matter 协议中温度常以毫开尔文 (mK) 为单位，2417 mK 即 21.84°C，虽然数值本身未达报警阈值，但在如此长的时间内持续单向升温且伴随‘幽灵’占用信号，强烈暗示热源未被移除。",
    "推理步骤 4: 风险评估。独居老人若因忘记关火或电器故障导致厨房过热，极易引发火灾。由于老人独居且可能无法及时察觉，此情况风险极高。"

    "02:10-04:15 期间厨房温度持续单调上升，从 ~23.2°C 升至 ~24.2°C，且无其他房间温度同步剧烈变化。",
    "厨房运动传感器在 02:10 短暂报告有人后，多次在长时间间隔内报告无人，存在数据不一致或传感器受热源干扰的可能性。",
    "整个时间段内，所有房间的运动传感器均显示无人，排除了正常家庭活动导致的高温可能性。"
  ],
  "recommended_actions": [
    "立即远程通知家属或紧急联系人，告知可能存在厨房火灾隐患。",
    "尝试通过智能家居系统远程检查厨房烟雾报警器状态，若已触发则启动应急响应。",

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。

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。

## 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",

    "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。

    "关键设备状态：入户门锁、烟雾报警器等关键安全设备未报告任何故障代码或异常触发，且窗户/门接触传感器仅在有人进出时变化，逻辑自洽。"

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。

    "关键安全设备运行正常：烟雾报警器（smoke_co_alarm）和漏水传感器（water_leak_detector）在提供的日志片段中未触发报警事件，且相关区域（如厨房灶具使用期间）的温度读数平稳，无火灾或漏水风险特征。"
