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": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "客厅温度传感器出现异常读数，包括瞬间跳变至-500及数据重复上报，表明设备存在硬件故障或通信错误。",
  "reasoning": [
    "1. 分析温度变化趋势：从08:10到13:45，客厅温度从25.36°C缓慢下降至24.74°C，符合夏季午后室内自然降温或空调运行的正常物理规律，其他房间（主卧、厨房等）也呈现相似的平稳下降趋势，说明环境整体正常。",
    "2. 识别异常数据点：在14:00:00，日志显示两条连续的`living_room_temp_sensor`记录，第一条为2480（合理），第二条突然变为2430（骤降5度，且与前一分钟无显著环境变化不符）。",
    "3. 确认严重故障：紧接着在14:05:00，日志再次出现两条连续记录，其中一条明确报告值为-500。根据Matter协议标准，-500通常表示测量值无效、传感器未连接或硬件损坏（Invalid Measurement）。这种极端的负值不可能由环境温度产生。",
    "4. 排除误报可能：虽然14:00的2430可能是瞬时干扰，但随后的-500确凿地证明了传感器无法提供有效数据。结合后续14:10又恢复为2440，这表明传感器处于间歇性失效或通信不稳定的状态，而非简单的漂移。"

  ],
  "recommended_actions": [
    "检查客厅温度传感器的电池电量或电源连接，尝试更换电池或重启设备。",
    "如果问题持续，建议更换该温度传感器，因为-500读数表明内部元件可能已损坏。",
    "暂时忽略该传感器的自动温控逻辑，改用手动控制或依赖其他房间的正常传感器数据进行估算。"

## 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",

    "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
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。

  "reasoning": [
    "1. 建立基准：观察日志中从07:15到13:00的数据，室内温度呈现典型的日间缓慢上升后随空调/自然通风下降的趋势。例如13:00时，客厅、厨房、主卧等所有传感器的读数均在24.8°C-25.0°C左右，表明此时全屋环境温度一致且正常。",
    "2. 识别异常点：在13:15，客厅温度传感器突然报告29.20 (29.2°C)，随后在13:35报告29.40，13:55报告29.60。这些数值显著高于当时其他所有房间的温度（如厨房25.03°C，主卧24.83°C）。",
    "3. 排除合理场景：虽然13:00客厅空调开启（OnOff=True），但空调通常旨在降低室温。若空调正常工作，室温应逐渐接近设定值（通常低于29°C）。即使空调故障导致过热，其他邻近区域（如餐厅、厨房）的温度并未同步飙升，说明并非局部热源（如烤箱、阳光直射）导致的真实高温。",
    "4. 确认故障模式：异常读数仅出现在客厅传感器，且表现为离群的高值，随后又迅速回落至正常范围（14:05回到24.80°C）。这种非物理性的、孤立的、剧烈的数值跳变是典型传感器硬件故障、校准错误或通信干扰的特征。"

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "sensor_malfunction",
  "threat_description": "洗衣机运行但倒计时不减少",

```json
{

  "threat_type": "none",
  "threat_description": "日志显示家庭环境运行正常，设备状态符合预期，未发现安全威胁或异常故障。",
  "reasoning": [
    "温度传感器数据合理：所有房间的温度读数（如客厅 24.97°C - 25.58°C）均在舒适且正常的范围内，且随时间变化呈现自然的波动趋势，无传感器漂移或卡死迹象。",
    "门锁操作逻辑正常：入户门在 07:50 被手动上锁（LockState=2），随后在 08:00、08:20 等时间点检测到门口有人进入（Occupancy=1），表明人员进出与门锁状态匹配，无非法入侵或尾随嫌疑。",
    "洗衣机状态正常：阳台洗衣机在 10:00 启动（OperationalState=1），并在后续多次报告倒计时为 2400 秒（40 分钟），这是标准的洗涤周期行为，未出现设备卡死或异常停机。",
    " occupancy 模式符合生活习惯：各房间的人员分布（主卧频繁有人，次卧和客厅间歇性有人）符合典型的日间居家活动模式，无长时间无人却门窗开启等异常情况。"
  ],
  "key_evidence": [
    "front_door_lock 在 07:50 执行手动上锁操作，且后续有正常的进出记录。",
    "balcony_laundry_washer 从 10:00 开始持续报告 CountdownTime = 2400，表明正在正常运行中。",
    "所有 temperature_sensor 读数稳定且在合理区间内，无突变或超出阈值的情况。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期校准温度传感器以确保长期准确性（非紧急）。"
  ]

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：

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。

  "reasoning": [
    "1. 观察日志时间线：在 2026-07-10T19:13:00，厨房温度传感器上报 `TemperatureMeasurement.MeasuredValue = None`，表明该时刻传感器未能提供有效读数，可能处于离线、重启或通信失败状态。",
    "2. 紧接着在 2026-07-10T19:15:00（仅2分钟后），同一传感器上报数值为 2298。结合前后文，19:10时儿童房温度为2300，19:20时为2292，19:40时厨房恢复后为2282。虽然2298在合理范围内，但之前的'None'值是一个明确的故障信号。",
    "3. 对比其他设备：在同一时间段内，客厅、主卧、儿童房的温度传感器均正常上报连续且符合物理规律（缓慢下降）的数值。唯独厨房传感器出现中断，排除了全屋网络波动导致所有传感器同时失效的可能性。",
    "4. 结论：这种间歇性的数据丢失（Null/None）是典型的传感器通信模块不稳定或内部电路故障的表现，属于设备健康问题。"
