## 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",

  ],
  "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。

## 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": [

    "推理步骤2: ...",
    "推理步骤3: ..."

    "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": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "洗衣机按预期完成工作周期，入户门传感器状态符合住户日常活动规律，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 分析目标设备（阳台洗衣机）状态：日志显示在 10:00 洗衣机启动 (OperationalState=1)，随后在 10:20 和 10:40 出现倒计时减少事件 (CountdownTime 从 2400s 降至 1200s)，表明设备正在正常运行洗涤程序。最终在 11:00 停止运行 (OperationalState=0)。整个过程耗时约 1 小时，符合典型洗衣机的运行时长，无异常中断或卡死迹象。",
    "2. 分析关联环境与安全设备：虽然重点房间是阳台，但日志中包含了大量玄关（entrance）的运动传感器数据。数据显示在 07:32 门锁手动开启后，玄关运动传感器多次触发 (Occupancy=1)，且间隔时间较长（如 08:07, 08:27, 09:02 等），这通常对应住户在家中的正常走动或短暂停留。这种低频、非连续的运动检测与“入侵”或“尾随”特征不符，更符合居家生活场景。",
    "3. 排除其他风险：日志中未出现烟雾报警、漏水检测、温度异常飙升或门窗非法开启等告警信息。所有温度读数均在合理范围内波动（25°C左右）。因此，结合洗衣机的工作逻辑和住户的活动模式，判定当前状态为正常。"

## 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。

    "1. 目标设备（阳台洗衣机）在 10:00 启动（OperationalState=1），并在 10:20 和 10:40 分别报告了倒计时时间（2400秒和1200秒），显示设备正在按预期进行洗涤程序并递减剩余时间。",
    "2. 在 11:00，洗衣机状态变为 OperationalState=0，且之前的倒计时逻辑符合标准洗衣周期（从10:00到11:00共60分钟，即3600秒，虽然日志中显示的中间点倒计时略有偏差，但整体流程完整：启动->运行->结束）。",
    "3. 检查关联环境数据：阳台门传感器（front_door_contact/entrance_occupancy等作为参考）在洗衣机运行期间（10:00-11:00）没有异常的开启记录表明有人闯入或长时间滞留导致异常；厨房、客厅等区域温度传感器读数在正常范围内（约25°C左右），无火灾或过热风险。",
    "4. 家庭成员活动轨迹正常：主卧、儿童房、餐厅等区域有正常的 occupancy 变化，符合白天家庭活动的常态，未发现长时间无人却设备异常活跃，或有人活动但关键安全设备失效的情况。"

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": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],

    "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": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "key_evidence": [
    "正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数出现严重漂移，数值异常偏高且波动剧烈，远超正常环境温度范围，可能导致空调控制失效或误报高温。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 09:00 到 17:00，living_room_temp_sensor 的 MeasuredValue 持续在 2540-2555 之间波动（对应约 25.4°C - 25.5°C），虽然看似在高温，但结合后续数据看趋势异常。",
    "推理步骤 2: 关键异常点出现在 17:00:00，该传感器读数瞬间跳变至 2520 (25.2°C)，随后在 17:10:00 骤降至 2344 (23.4°C)，并在之后持续下降至 2293 (22.9°C)。这种在短时间内（10 分钟内）发生超过 2°C 的快速降温，对于静止环境下的室内温度传感器来说极不自然，不符合热力学规律。",
    "推理步骤 3: 对比同一时间段内的 bedroom_temp_sensor 和 kitchen_temp_sensor，它们的读数变化相对平滑且符合昼夜温差逻辑（卧室从 24°C 左右缓慢降至 22°C 左右）。唯独 living_room_temp_sensor 在 17:00 前后的行为与其他传感器及物理常识不符，表明该传感器可能发生了校准漂移、固件 bug 或硬件故障，导致数据不可信。"
  ],
  "key_evidence": [
    "2026-08-23T17:00:00 时 living_room_temp_sensor 读数为 2520，而仅 10 分钟后的 17:10:00 读数骤降至 2344，降幅达 1.8°C/10min，远超正常热惯性衰减速度。",
    "同期 bedroom_temp_sensor 在同一时段内从 2580 平稳下降至 2249，变化曲线平滑，与客厅传感器的突变形成鲜明对比。"
  ],
  "recommended_actions": [
    "立即检查客厅温度传感器硬件连接及供电情况，排除接触不良导致的信号跳变。",
    "重置客厅温度传感器并重新校准，或暂时将其从自动化场景（如空调联动）中移除，改用备用方案或人工监测。",
    "联系设备制造商获取固件更新或技术支持，排查是否存在已知 Bug。"

## 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": [

    "推理步骤2: ...",
    "推理步骤3: ..."
  ],

    "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": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "客厅主灯在无人状态下开启并调暗，随后环境数据正常波动，未检测到安全威胁或设备故障。",
  "reasoning": [
    "1. 分析目标设备状态：日志显示在 20:10，living_room_light_1 被开启 (OnOff=True) 且亮度设为 180，随后在 20:18 亮度降至 30（调暗模式）。这通常是用户手动操作或自动化场景（如回家模式、观影模式）的结果。",
    "2. 结合 occupancy 传感器判断：尽管 living_room_occupancy 在 20:00 和 21:00 均报告为 0（无人），但在 20:10 开灯时并未立即触发“无人开灯”的强异常警报，因为存在多种正常解释：a) 用户刚离开不久，传感器有延迟；b) 用户通过手机 App 或语音助手远程/定时控制灯光，而非依赖人体感应；c) 这是一个预设的自动化场景（例如晚上自动开启氛围灯）。",
    "3. 检查其他关联数据：同一时间段内，所有温度传感器读数呈现正常的夜间缓慢下降趋势（从 ~2275 降至 ~2266），无剧烈跳变或停滞，表明传感器工作正常，无 sensor_stuck 或 sensor_drift 现象。厨房、卧室等区域也无火灾、漏水或入侵迹象。",
    "4. 综合评估：虽然“无人开灯”在某些严格的安全策略下可能被视为可疑，但在智能家居日常使用中，非 occupancy 触发的灯光控制非常普遍。鉴于没有伴随门窗异常开启、烟雾报警或其他入侵迹象，且灯光行为符合常规使用习惯（开灯后调暗），判定为正常行为。"

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": [
    "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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本是小幅波动；异常样本出现不可能的极端跳变。"
  ],
  "key_evidence": [
    "正常样本是小幅波动；异常样本出现不可能的极端跳变。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "正常样本是小幅波动；异常样本出现不可能的极端跳变。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}
