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",

    "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": "high",

  "threat_description": "客厅温度传感器出现间歇性极高数值读数（约29.2°C-29.6°C），与周围环境和空调运行状态严重不符，疑似传感器故障或数据上报错误。",
  "reasoning": [
    "1. 环境背景分析：日志显示时间为8月4日白天，室外气温较高。客厅其他设备（如厨房、卧室）的温度读数在23°C-25°C之间波动，符合夏季室内开启空调后的正常范围。",
    "2. 异常数据识别：在13:15、13:35和13:55三个时间点，客厅温度传感器分别上报了2920 (29.2°C)、2940 (29.4°C) 和 2960 (29.6°C) 的数值。这些数值显著高于同一时间段内其他房间的温度（如卧室~24°C，厨房~25°C）。",
    "3. 逻辑矛盾验证：在13:00时，客厅空调刚刚开启（OnOff=True）。如果室温真的升至29°C以上，空调应持续高负荷运行以降温。然而，随后的读数迅速回落至24°C左右（如13:40为24.81°C），且没有伴随空调关闭或故障的其他迹象。这种瞬间飙升后迅速恢复的模式不符合热惯性物理规律，极可能是传感器内部元件故障、校准漂移或通信数据包错误导致的“毛刺”现象。"

## 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": "卧室温度传感器读数出现严重异常漂移，数值远超正常室温范围（2271-2556），疑似传感器故障或数据编码错误。",
  "reasoning": [
    "1. 分析温度数值量级：日志中所有温度传感器的 `MeasuredValue` 均在 2200 至 2600 之间。在 Matter 协议及常见的智能家居标准中，温度通常以摄氏度 (°C) 或华氏度 (°F) 表示，或者以毫开尔文 (mK) 表示。",
    "2. 排除正常物理环境：如果单位是摄氏度，22°C-25°C 是舒适室温，但日志显示的是 2271-2556，这相当于 2271°C，显然不可能。如果单位是华氏度，2271°F 更是极端高温。",
    "3. 验证毫开尔文 (mK) 假设：Matter 协议中 TemperatureMeasurement Cluster 的 `MeasuredValue` 通常定义为 int16s，单位为毫开尔文 (mK)。即 1 mK = 0.001 K。若值为 2271 mK，则温度为 2.271 K (-270.88°C)，这是接近绝对零度的极低温，对于室内环境完全不可能。",
    "4. 识别数据异常模式：观察数值变化趋势，从凌晨 00:00 到上午 10:00，数值呈现缓慢上升趋势（2271 -> 2556）。这种线性/非线性增长不符合自然室温波动（夜间应略低或稳定，清晨随日照可能升高，但幅度极小且不会跨越几百个单位）。",
    "5. 结论：这些数值既不是有效的摄氏度/华氏度，也不是有效的毫开尔文。最可能的解释是传感器固件存在 Bug，导致上报的数据被错误地放大了 100 倍（例如实际 22.71°C 上报为 2271），或者是传感器硬件损坏产生了错误的原始数据。无论哪种情况，都属于传感器数据异常。"
  ],
  "key_evidence": [
    "master_bedroom_temp_sensor 在 00:05 报告 2274，10:00 时 master_bedroom_temp_sensor 报告 2541，数值持续高位且无合理物理意义。",
    "所有房间的温度传感器（living_room, kitchen, second_bedroom）均报告类似的异常高值（2200-2500区间），表明可能是系统性问题或普遍的数据解析/上报错误。",
    "Occupancy sensors 工作正常（0/1切换），证明通信链路基本正常，问题集中在温度数据的数值本身。"
  ],
  "recommended_actions": [
    "检查并更新卧室及其他房间温度传感器的固件版本，排查是否存在已知的数据上报 Bug。",
    "校准或更换疑似故障的温度传感器，确认其实际测量值是否在合理范围（如 15-30°C）。",
    "检查智能家居网关或自动化规则中是否对温度阈值进行了错误配置，导致误报或数据处理异常。"

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": "门窗传感器状态与窗帘位置矛盾",
  "reasoning": [
    "推理步骤1: 窗户/窗帘相关状态前后矛盾",
    "推理步骤2: 没有配套的合理位置变化",
    "推理步骤3: 更像传感链路异常"
  ],
  "key_evidence": [
    "窗户/窗帘相关状态前后矛盾",
    "没有配套的合理位置变化",
    "更像传感链路异常"
  ],
  "recommended_actions": [
    "判断为开闭状态感知异常，建议检查相关传感器。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "low",
  "threat_type": "intrusion",
  "threat_description": "存在异常，但原因更可能属于其他类别。",
  "reasoning": [
    "推理步骤1: 日志里有异常，但我把它归因为另一类威胁。"
  ],
  "key_evidence": [
    "窗户/窗帘相关状态前后矛盾"
  ],
  "recommended_actions": [
    "建议按该错误类别处理。"
  ]
}


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. 识别异常数据点：在 2026-08-24T14:05:00，卧室温度传感器上报了 -500 的测量值。根据 Matter 协议标准，TemperatureMeasurement 的有效范围通常在 -273.15°C 到 300°C 之间（对应整数值为 -27315 到 30000）。-500 虽然物理上可能代表 -5.00°C，但在该时间段内，其他房间（客厅、厨房）温度均在 23-25°C 左右，且卧室前一分钟为 24.30°C，后一分钟为 24.40°C。-5.00°C 与周围环境温差过大，极大概率是传感器故障导致的错误读数（如溢出、短路或软件Bug），而非真实环境温度。",
    "2. 分析后续行为模式：在异常读数后，传感器立即恢复至正常范围（24.40°C），但随后的读数（23.70, 23.61, 23.32...）呈现出比平时更剧烈的下降趋势，从 ~24.3°C 降至 ~22.4°C，降幅近 2°C。考虑到这是白天（14:00-17:00），且老人活动频繁（多个房间有 occupancy 记录），室内温度通常应保持稳定或随空调/暖气微调，如此大幅度的持续下降不符合常规热惯性规律，暗示传感器可能存在漂移或间歇性故障。",
    "3. 排除环境因素：同一时间窗内，客厅和厨房的温度变化平缓（例如客厅从 24.70°C 缓慢降至 23.32°C），没有证据显示整个房屋发生了急剧降温事件（如窗户全开导致全屋失温，通常会有接触传感器报警，但日志中未提及卧室窗户打开，仅有一次窗帘动作且位置为100%即关闭状态）。因此，问题局限于卧室温度传感器本身。"

## 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。

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "系统运行正常，未发现安全威胁或设备故障。所有传感器读数符合物理规律，设备状态逻辑一致。",
  "reasoning": [
    "温度数据合理性分析：日志中的温度值（如 2497-2560）明显为毫摄氏度（mK），换算后约为 24.9°C - 25.6°C。该数值范围符合夏季室内空调开启或自然通风下的正常室温波动，且厨房温度略高于卧室符合热力学常识，无传感器漂移或卡死迹象。",
    "设备状态逻辑验证：阳台洗衣机（balcony_laundry_washer）在 10:00 启动（OperationalState=1），随后多次报告倒计时（CountdownTime=2400，即 40 分钟）。虽然倒计时未递减，但这极可能是 Matter 协议中设备周期性上报固定状态或处于待机/暂停等待用户交互的常见行为模式，并非设备卡死（Actuator Stuck），因为设备并未报错且处于‘运行中’状态。",
    " occupancy 与活动关联：全屋运动传感器在上午时段大部分时间为空（0），仅在特定时间点有短暂活动记录（如 07:30、08:00 等），这与家庭早晨起床、洗漱、准备出门的时间线吻合。没有发现异常入侵（如无人时门窗被打开）或长时间异常滞留的情况。",
    "关键事件排查：日志中未出现烟雾报警、漏水检测、门锁异常解锁或窗户非法开启等高危事件。所有接触式传感器（门窗）均保持闭合或正常状态。"
  ],
  "key_evidence": [
    "温度读数换算后（~25°C）处于舒适居住区间，且各房间温差符合物理预期。",
    "洗衣机 OperationalState 持续为 1 且 CountdownTime 稳定，符合设备周期性心跳或待机逻辑，无故障代码。",
    "全时段无 intrusion（入侵）、fire_risk（火灾风险）或 water_leak（漏水）相关告警信号。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统状态健康。",
    "建议定期查看洗衣机完成后的状态更新，确认其能正常进入‘完成’或‘停止’状态。"
  ]
