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。

  "confidence": "medium",
  "threat_type": "actuator_stuck",
  "threat_description": "灯的 OnOff 与 Level 矛盾",
  "reasoning": [

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 living_room_light_1 状态正常，无安全威胁或异常行为。",
  "reasoning": [
    "推理步骤 1: 检查目标设备日志，发现 living_room_light_1 在 20:10:00 被设置为关闭 (OnOff=False) 且亮度为 180，随后在 20:12:00 再次报告关闭状态，最后在 22:47:00 再次确认关闭。这些操作符合用户手动控制或自动化场景（如离家模式）的正常逻辑，未出现设备失控、频繁跳变或无法响应指令的故障特征。",
    "推理步骤 2: 结合上下文环境分析，虽然客厅运动传感器在 20:10:00 时仍检测到有人 (Occupancy=1)，但此时餐厅灯已关闭，且后续时间轴显示家庭成员活动分散在不同房间（如儿童房、主卧），这种多房间同时有人但特定区域灯光关闭的情况属于正常的家庭作息分布，并非入侵迹象。",
    "推理步骤 3: 温度传感器数据显示客厅温度从下午的 24.7°C 逐渐下降至晚上的 22.4°C 左右，变化趋势平缓且符合夜间自然降温规律，未发现传感器漂移、卡死或读数突变等异常情况。"
  ],
  "key_evidence": [
    "living_room_light_1 的状态变更 (OnOff/LevelControl) 时间戳清晰，逻辑连贯，无冲突事件。",
    "同期其他房间（厨房、儿童房、主卧）的 occupancy 和 temperature 数据表明家庭处于正常的晚间活动状态，排除了单人非法入侵的可能性。",
    "temperature_sensor 读数随时间呈现合理的线性下降趋势，未出现物理上不可能的数值跳跃。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",

## 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。

Rejected response:

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 (balcony_laundry_washer) 运行状态正常，无安全威胁或异常行为。",
  "reasoning": [
    "推理步骤 1: 检查洗衣机状态日志。在 2026-08-12T10:00:00 时，洗衣机报告 OperationalState 为 1（通常表示运行中），随后在 10:20:00、10:40:00 和 11:00:00 多次报告 CountdownTime 为 2400 秒（40 分钟）。这表明设备正在按计划执行洗涤程序，且倒计时逻辑一致，未出现状态突变或卡死现象。",
    "推理步骤 2: 结合环境上下文分析。日志显示该时间段内（07:00 - 12:58）家庭多个区域（客厅、主卧、厨房等）有人员活动记录（Occupancy = 1），且温度传感器读数稳定在 25°C 左右（2500-2560 毫开尔文/摄氏度单位），符合夏季早晨至中午的正常居家生活场景。",
    "推理步骤 3: 排除关联风险。虽然阳台门传感器未在日志中明确标记为“打开”，但考虑到洗衣机位于阳台且处于运行状态，若门被非法闯入，通常会伴随入侵报警或运动传感器异常触发。当前日志中未见此类冲突事件，且入户门和玄关的 occupancy 变化符合家庭成员正常进出规律，未发现尾随或入侵迹象。"

System:
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。

System:
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：

## 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": [
    "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。

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",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

    "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。

  "threat_description": "客厅温度传感器出现严重读数异常，包括负值、跳变及持续下降趋势，表明设备硬件故障或通信错误。",
  "reasoning": [
    "1. 数据格式与单位分析：Matter协议中TemperatureMeasurement.MeasuredValue通常以厘氏度（centi-degrees Celsius）为单位，即实际温度 = 读数 / 100。日志中大部分读数为2300-2500之间，对应23°C-25°C，符合正常室温范围。",
    "2. 识别异常点A（负值）：在[2026-08-22T14:05:00]，客厅温度传感器报告值为-500，即-5.0°C。对于室内环境，除非空调极度异常或传感器损坏，否则不可能瞬间降至冰点以下，且随后立即恢复至2440（24.4°C），这极可能是传感器内部ADC转换错误或数据包损坏导致的无效读数。",
    "3. 识别异常点B（非物理规律的趋势）：从[2026-08-22T13:35:00]到[2026-08-22T16:50:00]，客厅温度读数从2480持续单调下降至2369，降幅达1.1°C。虽然夏季午后气温可能波动，但在短短3小时内，室内无人员活动（Occupancy始终为0）、无空调开启记录（根据上下文推断，若空调开启应有状态变化日志，且其他房间温度未呈现同步剧烈变化）的情况下，这种线性且持续的下降不符合热惯性规律，更像是传感器漂移或电池电量不足导致的测量失真。",
    "4. 排除法：其他房间（如主卧、儿童房、厨房）的温度读数在同一时间段内保持相对稳定或在合理范围内波动（例如主卧从2479降至2372，但幅度较小且与其他房间有差异），说明并非全屋环境温度骤降，而是特定于客厅传感器的局部故障。"
