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",

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: 对比卧室温度传感器数据（约 2240-2300），其数值变化趋势平缓且符合夜间降温后的回升规律（考虑到空调运行），而客厅温度在住户出现前（03:14 Occupancy=1）和出现后持续攀升至 2400+ 的异常高位，这种跨房间的巨大温差（>100 单位）不符合热力学常识。",
    "推理步骤 3: 结合独居老人场景，虽然不能直接断定是入侵者带来的热源，但传感器数据的剧烈漂移（Drift）会导致温控系统失效、能耗激增，甚至掩盖真实的火灾隐患（如真实火灾时传感器可能因故障无法上报正确数据），属于高优先级的设备可靠性问题。"

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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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",

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。

  "threat_description": "日志显示正常的夜间离家模式及次日清晨的入户开门行为，未发现安全威胁。",
  "reasoning": [
    "推理步骤 1: 凌晨 04:00-04:30 期间，所有房间（客厅、卧室、卫生间）的运动传感器均报告无人状态 (Occupancy=0)，且此时门锁处于锁定状态 (LockState=2)，符合深夜无人居住的常态。",
    "推理步骤 2: 凌晨 04:09 客厅灯开启可能是系统自动唤醒或误触，但随后在 04:30 再次确认全屋无人，且直到 10:02 之前无其他异常活动，排除了入侵者潜伏的可能性。",
    "推理步骤 3: 晚上 23:04 用户手动解锁并打开前门 (LockOperationType=0, OperationSource=Manual)，随后门锁状态变为未锁定 (LockState=1)，这是典型的住户正常回家行为，与之前的无人状态形成合理的闭环。"

  "key_evidence": [
    "23:04:00 前所有房间运动传感器持续报告 Occupancy = 0",
    "23:04:35 门锁操作源为 Manual，且操作后状态从锁定变为未锁定，符合住户回家逻辑"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续监控后续时段，确保白天离家时门锁能自动重新锁定。"
