## 任务
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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。

    "分析空闲区域：次卧（second_bedroom）和卫生间（bathroom）持续显示无占用（Occupancy = 0），这符合夜间大部分家庭成员在卧室休息的预期，没有发现异常入侵者进入私密空间或长时间滞留卫生间的迹象。",
    "综合判断：所有涉及的设备均为运动/占用传感器（occupancy_sensor），且状态变化逻辑连贯（有人->无人->有人），未发现门锁异常开启、烟雾报警、漏水或其他危险设备触发的情况，因此判定为正常行为。"
  ],
  "key_evidence": [

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。

## 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",

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. 卫生间活动合理性：主卫运动传感器多次出现 Occupancy=0 的断开信号（如22:28, 22:58, 23:28），间隔约30分钟，这通常对应住户使用卫生间后离开的正常行为，未发现长时间滞留或异常静止导致的跌倒风险。",
    "3. 环境数据稳定性：温度传感器读数在22.4°C至22.7°C之间波动（Matter协议中通常以0.01摄氏度为单位，即2242代表22.42°C），变化幅度极小且平稳，无剧烈跳变，表明传感器工作正常，无火灾或极端天气引发的环境异常。",

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",

  ],
  "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。

    "1. 温度数据合理性分析：日志中的温度传感器数值（如2241, 2144等）明显高于标准摄氏度范围（0-50°C），这符合Matter协议中TemperatureMeasurement Cluster使用厘氏度（centi-degrees Celsius）编码的标准（即除以100后为22.41°C, 21.44°C）。这些数值在人体舒适范围内波动，且各房间温差合理（卧室较凉，客厅/厨房略高），无传感器故障迹象。",
    "2. 人员活动轨迹逻辑自洽：22:15至23:55期间，客厅运动传感器多次触发（Occupancy=1），表明有人在客厅活动。同时，卧室和卫生间传感器也有间歇性触发（如22:17卧室有人，22:36、23:06、23:36卫生间无人/有人状态切换），这符合典型的睡前洗漱、休息及夜间起夜的行为模式。",
    "3. 照明与设备控制正常：22:42卧室灯光开启（Level=33，低亮度），22:56关闭，随后22:58卧室无人。这一系列动作与人员进入卧室休息并关灯睡觉的行为完全一致。没有发现长时间无人却开灯、或深夜频繁开关门等可疑行为。",
    "4. 无关键安防事件：入户门锁、窗户传感器、烟雾报警器、漏水传感器在此期间均无报警或异常状态上报。所有数据点均在预期范围内，未发现入侵、火灾、泄漏或设备故障的迹象。"
  ],
  "key_evidence": [
    "温度读数2241-2278对应22.4-22.8°C，属于正常室温范围，非传感器漂移。",
    "卧室灯光在22:42开启并在22:56关闭，伴随卧室 occupancy 从1变为0，符合就寝行为。",
    "客厅 occupancy 持续活跃，而卧室最终无人，符合家庭成员在客厅活动后各自休息的常态。"
  ],
  "recommended_actions": [
    "无需采取任何行动，系统运行正常。",
    "建议继续保持当前的监控策略，定期校准温度传感器以确保长期数据准确性。"

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。

    "3. **设备控制符合习惯**：22:12 左右，住户关闭了客厅主灯、玄关灯和空调，并打开了卧室灯，这是典型的“结束客厅活动，准备进入卧室休息”的行为模式。",
    "4. **无异常环境数据**：温度读数在正常范围内波动（21-23°C），无烟雾报警、漏水或灶具异常开启的记录。卫生间传感器间歇性归零（如 22:07, 22:37）可能是短暂无人或传感器灵敏度问题，但未伴随其他危险信号，且频率不高，不足以判定为故障或异常。"

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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。

{
  "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: 日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "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": [
    "继续监测，无需立即处置。"
  ]
}

{
  "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。"
  ],
