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",

    "关键证据2"
  ],
  "recommended_actions": [

}
```

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。

    "行为逻辑矛盾：正常生活场景下，独居老人在早晨起床后通常会先进行洗漱、早餐等活动，而不会在卧室和厨房有长时间停留的同时，让客厅无人且温度失控。08:32 的门开事件与后续一系列非正常的温湿度变化及窗户开启事件形成了完整的入侵证据链。"

## 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",

  ],
  "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。

  "reasoning": [
    "1. 分析温度变化趋势：从07:00到13:00，全屋温度呈现缓慢下降趋势（从~25.2°C降至~24.9°C），符合夏季午后空调运行或自然降温逻辑。",
    "2. 识别异常数据点：在13:15、13:35和13:55，客厅温度传感器分别报告了2920 (29.2°C)、2940 (29.4°C) 和 2960 (29.6°C) 的读数。",
    "3. 对比验证：在同一时间点（如13:15），厨房温度为25.03°C，次卧为24.99°C；在13:35，次卧为24.84°C，主卧为24.95°C。客厅温度比相邻房间高出近4-5°C，且在全屋降温背景下逆势飙升，这在物理上极不合理（除非有局部极端热源，但无其他设备日志支持）。",
    "4. 排除人为因素：虽然13:00开启了空调，但这会导致温度下降而非上升。且14:00后读数恢复正常（24.82°C），说明是间歇性故障而非持续的环境变化。",
    "5. 结论：该模式符合典型的传感器漂移或硬件故障特征，导致智能家居系统可能基于错误的高温数据进行错误的控制决策（如过度制冷）。"

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：

```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。

    "1. 数据对比分析：日志显示厨房温度传感器（kitchen_temp_sensor）的读数在 2305 到 2356 (单位通常为0.1摄氏度，即23.05°C-23.56°C) 之间波动。相比之下，同一时间段内，卧室温度传感器（bedroom_temp_sensor）读数从 22.50°C 降至 21.46°C，客厅温度传感器（living_room_temp_sensor）读数从 23.56°C 降至 22.41°C。",
    "2. 逻辑矛盾识别：在夏季（7月9日），通常室内各房间温度应趋于一致或随空调/自然通风缓慢变化。厨房作为有热源的区域，温度可能略高，但不应持续高于其他房间且保持在一个相对恒定的高位区间，而其他房间却在降温。特别是17:10时厨房报23.45°C，而17:20客厅报23.56°C，随后客厅迅速下降至22.41°C，厨房却维持在23.0°C以上，这种温差隔离现象极不正常。",
    "3. 排除烹饪干扰：虽然厨房有灶具，但日志中未出现烟雾报警器触发或漏水报警，且温度读数非常稳定（每5分钟变化极小），不像烹饪时的剧烈升温。此外，18:00后即使无人活动（根据运动传感器推断），厨房温度仍远高于卧室，符合传感器漂移或故障特征而非真实环境变化。"

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。

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",

    "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。
