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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

## 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",

    "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。

    "3. 排除环境因素：虽然12:32有窗帘打开动作，但通常不会导致室内温度在几分钟内上升近5度并持续波动。更可能的原因是传感器本身硬件故障、校准失效或通信数据包损坏导致的数值错误。",
    "4. 确认恢复：14:00之后，温度读数恢复正常范围（24.67°C及以下），进一步证实了之前的读数是偶发性故障而非真实的环境变化。"

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

    "2. 识别异常点：在[2026-07-29T14:05:00]时刻，living_room_temp_sensor报告值为-500。在物理世界中，除非发生极端冷冻事故，否则室内温度不可能瞬间降至-5.00°C。且该负值与前后时刻的正常正温值（2430和2461）形成剧烈跳变，不符合热惯性规律。",
    "3. 排除其他干扰：虽然同一时间entrance_occupancy有活动记录，但入户门的活动不会导致客厅内部温度传感器产生负值错误。该数值极有可能是传感器芯片故障、ADC转换错误或数据包传输中的位翻转导致的无效数据。"

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：

  "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。

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

  "reasoning": [
    "分析目标设备 living_room_temp_sensor 的温度读数序列。在正常时间段（如08:10至13:55），读数在22.8°C至25.5°C之间波动，符合夏季室内空调环境的正常范围。",
    "在14:00时，传感器连续两次上报2471和2430，虽然数值较低但仍处于合理物理范围内（可能受空调冷风直吹影响）。",
    "关键异常点出现在14:05:00，living_room_temp_sensor 上报 TemperatureMeasurement.MeasuredValue = -500。根据Matter协议及通用温度传感器标准，摄氏度通常以厘度（centi-degrees）为单位存储，即-500代表-5.00°C。然而，结合上下文，前一刻为24.30°C，后一刻（14:10）恢复为24.40°C，且其他房间（如儿童房、厨房）在同一时段并未出现如此剧烈的全局降温（从24°C降至-5°C再回升），这极不符合物理规律。",
    "-500 (即-5°C) 对于正在使用空调的客厅来说是一个极端的低温值，且这种瞬间的断崖式下跌并迅速恢复，是典型的传感器数据溢出、通信丢包导致的默认错误值，或者传感器内部ADC转换故障的特征。",
    "尽管后续读数恢复正常，但该异常事件足以判定为传感器 malfunction（故障/失灵），因为它破坏了数据的连续性和可信度，可能导致基于此数据的自动化控制（如空调温控）失效或误判。"
