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

  "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": [
    "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。

    "2. 温度数据分析：各房间温度传感器读数在22.4°C至22.8°C之间波动（Matter协议中通常以0.01摄氏度为单位，即2257代表22.57°C）。数值变化平缓且处于舒适区间，无剧烈跳变，表明空调系统运行稳定或环境温度自然调节，不存在火灾导致的温度骤升或传感器故障。",
    "3. 关键安防设备状态：日志中未出现入户门锁的异常开启记录、窗户传感器的触发报警、烟雾/一氧化碳报警器的激活或漏水传感器的警报。结合无人活动的背景，家庭环境处于安全的非活跃状态。"

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
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",

}
```

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。

    "2.  温度数据分析：日志中记录的温度值范围在 2242 到 2279 之间。根据 Matter 协议标准，TemperatureMeasurement.MeasuredValue 的单位是厘氏度（cHDC），即数值除以100得到摄氏度。因此，实际室温约为 22.4°C 至 22.8°C。这是一个非常舒适且稳定的室内温度区间，没有剧烈波动，排除了火灾（高温）或设备故障导致的极端读数。",
    "3.  设备状态一致性：在长达近2小时的观察窗口内，除了温度传感器的周期性上报外，没有任何门锁、窗户、烟雾报警器或漏水传感器的异常触发事件。所有关键安防设备均保持静默，进一步证实了环境的安全性。"

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。

## 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
{
  "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的夜间居家活动模式。",
  "reasoning": [
    "1. 人员活动分析：日志显示住户在21:55至23:45期间主要在卫生间（bathroom）和卧室（bedroom）活动，客厅（living_room）也有持续 occupancy 信号。这种分布符合晚间洗漱、休息或睡前准备的习惯。",
    "2. 设备状态逻辑性：卧室灯在22:35关闭，随后在22:39以低亮度（Level=10）重新开启，这通常是用户调整灯光以适应睡眠环境的行为，属于正常操作而非故障。",
    "3. 传感器数据稳定性：温度传感器读数在合理范围内波动（约21.5°C - 22.7°C），变化平缓且符合室内热惯性特征，无剧烈跳变表明传感器工作正常，无漂移或故障迹象。",
    "4. 关键安防设备无异常：入户门锁、窗户传感器及烟雾报警器在此期间无任何触发或异常状态报告，排除了入侵、火灾或非法进入的风险。"
  ],
  "key_evidence": [
    "卧室灯在22:35关闭后于22:39以低亮度重新开启，符合睡前调光习惯。",
    "卫生间和卧室运动传感器在21:55-23:45期间多次触发，与住户夜间活动轨迹一致。",
    "所有温度传感器读数稳定在21-23摄氏度之间，无异常波动。",
    "无门窗传感器报警或门锁异常操作记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控夜间长时间无人区域（如厨房、玄关）的状态，以确保彻底入睡后的安全性。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]

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。
