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。

  "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",

## 任务
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

请按以下 JSON 格式回答：

```json

  "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。

    "推理步骤 2: 漏水事件发生在 09:02:00，而该时间点前后（08:59:00）儿童房和入户门均有人员活动迹象，结合 09:00:00 主卫灯开启，推断用户正在使用卫生间。",
    "推理步骤 3: 虽然传感器在 09:05:00 自动恢复为 False，但这可能是由于水流暂时停止或传感器误报，鉴于水损风险不可逆，不能简单视为正常波动，必须确认为真实威胁进行排查。"

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

  "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",

## 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。

    "2. 这种高频次的断连重连（Flapping）不符合正常的网络波动特征，通常指向 Wi-Fi/Thread 信号干扰、电源适配器接触不良、或者设备内部主板/通信模块故障。",
    "3. 虽然温度传感器数据正常且人员活动轨迹符合日常作息（早晨起床、活动），但空调作为关键环境控制设备，其不稳定性可能导致温控失效或系统资源浪费，属于明确的设备健康异常。"

  "threat_type": "sensor_malfunction",

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",

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": "客厅温度传感器读数异常偏高且单位错误，导致空调频繁离线重连，疑似传感器硬件故障或数据解析错误。",
  "reasoning": [
    "1. 分析温度数值合理性：日志显示客厅温度从 2364 持续上升至 2558。在 Matter 协议中，TemperatureMeasurement.MeasuredValue 通常以厘氏度（centi-degrees Celsius）为单位，即除以 100 得到摄氏度。若按此标准，室温为 23.6°C - 25.6°C，属于正常舒适范围。然而，结合其他房间（如厨房、卧室）在同一时间段内也报告了类似的数值（如 2480, 2505 等），且所有房间温度高度一致并同步上升，这不符合物理规律（不同房间因光照、热源差异应有温差）。更关键的是，如果这些数值代表实际摄氏度（2364°C），则显然不可能；如果代表华氏度或其他未缩放值，需进一步验证。但最可疑的是，所有传感器数值完全同步变化，暗示可能是系统级上报错误或传感器本身故障导致的“假性”高温/低温读数。",
    "2. 关联设备行为异常：客厅空调（living_room_ac）在 09:00 至 09:40 之间出现了多次 'DeviceOffline' 和 'DeviceOnline' 事件。这种频繁的断线重连通常由以下原因引起：a) 网络信号不稳定；b) 设备过热保护；c) 控制逻辑冲突。考虑到此时段室内实际温度（假设传感器读数有误，实际可能正常或略高）并未达到极端高温，且其他房间无类似空调离线记录，重点怀疑是空调试图根据错误的温度反馈进行调节，或者传感器数据异常触发了某种保护机制/通信拥塞。",
    "3. 排除环境因素：虽然早晨气温升高是正常的，但 03:00 到 11:00 期间，所有房间温度传感器读数呈现完美的线性或平滑上升趋势，且数值极其接近（例如 09:00 时客厅 2548，厨房 2545，主卧 2551，次卧 2551）。这种缺乏空间差异的“同质化”升温极不自然，强烈暗示存在传感器校准失效、固件 Bug 或数据上报通道异常。此外，09:00-09:40 期间空调的反复离线与温度读数的波动（虽缓慢但持续）时间窗口重合，表明两者存在因果联系。"

    "客厅温度传感器读数在 03:00-11:00 期间从 2364 单调递增至 2558，且与其他房间传感器数值高度同步，缺乏空间温差，疑似数据异常。",
    "客厅空调（living_room_ac）在 09:00-09:40 期间发生 3 次 DeviceOffline/Online 循环，可能与异常温度数据或由此引发的控制逻辑有关。",
    "所有房间温度传感器数值在相同时间点几乎一致（如 09:00 左右均在 2540-2550 区间），违背物理常识。"
  ],
  "recommended_actions": [
    "检查客厅温度传感器的固件版本，尝试重启该传感器以重置连接。",
    "核实温度传感器的配置参数，确认 MeasuredValue 的单位定义是否正确（是否为厘氏度），并对比手动温度计读数以校准偏差。",

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": [
    "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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "客厅温度传感器读数异常偏高且持续上升，同时关联的空调设备出现频繁离线/在线波动，表明传感器可能存在故障或空调控制逻辑失效。",
  "reasoning": [
    "1. 分析温度数据趋势：从03:00到10:50，客厅温度传感器（living_room_temp_sensor）的读数从2361（约23.6°C）持续攀升至2556（约25.5°C）。虽然夏季室温升高是可能的，但在凌晨03:00-06:00期间，室内无人（Occupancy=0），且卧室和厨房温度相对稳定（23.8-24.9°C区间），客厅温度却显著高于其他房间并持续单调上升，这不符合正常热平衡规律，暗示传感器可能漂移或故障。",
    "2. 分析空调状态与温度的关系：日志重点关注的客厅空调（living_room_ac）在09:00至09:40之间出现了三次 'DeviceOffline' 和 'DeviceOnline' 事件。如果空调正常工作以应对高温，它应该保持在线并制冷。频繁的断连通常意味着通信模块故障、电源问题或严重的系统错误。",
    "3. 综合判断：高且持续上升的温度读数（即使转换为摄氏度后仍显示为上升趋势）结合空调设备的严重不稳定状态，极大概率指向传感器读数失真导致空调无法正确响应，或者空调本身因硬件/软件故障导致无法调节温度，进而使环境温度失控。考虑到Matter协议中TemperatureMeasurement.MeasuredValue单位为厘氏度（celsius * 100），2556代表25.56°C，虽然绝对值未达危险高温，但相对于其他房间的低温，这种差异以及空调的离线行为构成了设备健康层面的异常。"
