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

  "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。

  "threat_description": "厨房温度传感器读数异常偏高且出现数据丢失，疑似设备故障或环境极端异常。",
  "reasoning": [
    "1. 分析温度数值格式：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。日志中的读数如2543对应25.43°C，属于正常室温范围；而初始的2280对应22.80°C，也属正常。",
    "2. 识别异常模式：从06:21开始，kitchen_temp_sensor出现MeasuredValue = None，随后在06:25恢复为2489 (24.89°C)。此后温度读数持续快速上升，从07:00的2508 (25.08°C) 飙升至10:00的2550 (25.50°C)，并在11:28前一直维持在25.4-25.6°C的高位区间。",
    "3. 对比其他设备：同一时间段内，living_room_temp_sensor读数在25.16°C - 25.59°C之间波动，bedroom_temp_sensor在23.77°C - 24.50°C之间。虽然客厅温度也略高，但厨房温度不仅绝对值较高，且在06:21出现了数据中断（None），这通常是传感器硬件故障、电池耗尽或通信模块不稳定的典型表现。",
    "4. 排除真实火灾风险：尽管厨房温度看似“偏高”（相对于卧室），但并未达到危险阈值（如>40°C或>50°C），且烟雾报警器（smoke_co_alarm）在日志期间未触发任何报警事件。结合独居老人背景，更可能是传感器漂移或故障导致的误报数据，而非真实的火灾前兆。"

  "threat_description": "厨房温度持续异常升高且伴随人员活动，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，从凌晨 05:37 卧室灯开启开始，到 06:21 厨房温度传感器读数丢失（None），再到 06:25 恢复为 2489mK (约 24.9°C)，随后在 07:00-11:28 期间，厨房温度传感器读数持续攀升至 2543mK (约 25.4°C) 并维持在高位。虽然绝对温升值看似不大，但结合独居老人背景，需关注设备是否处于‘干烧’或故障状态导致无法正确报告高温，或者环境温度本身就在异常累积。",
    "推理步骤 2: 关键异常点在于 06:21:00 的 `kitchen_temp_sensor` 报告值为 `None`。在 Matter 协议中，这通常意味着传感器通信中断、供电不足或硬件故障。对于一个正在运行（有 occupancy 记录）的厨房环境，传感器突然失效是极不正常的，可能导致烟雾报警器未能及时联动或用户无法通过远程监控得知真实情况。",
    "推理步骤 3: 尽管后续温度数值恢复并有小幅波动，但考虑到这是针对‘独居老人’的安全分析，任何关键安全传感器（尤其是厨房温度/烟雾相关）的间歇性失效（Sensor Malfunction/Stuck）都被视为高危事件。此外，06:50 门锁被手动操作（LockOperationType=1 解锁，0 上锁），随后不久（06:55）卧室有人，07:00 厨房再次有人，显示老人可能刚起床进入厨房。如果此时厨房设备（如灶具）因故障未关闭，而温度传感器又曾失效，火灾风险极高。",
    "推理步骤 4: 综合来看，核心问题不是温度数值本身的微小变化，而是 `kitchen_temp_sensor` 在关键时间段（06:21）出现数据丢失（None），以及随后长时间的高频上报和数值维持高位，暗示传感器可能已损坏或卡死（Stuck/Malfunction），无法准确反映潜在的高温危险，属于严重的安全隐患。"

## 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。

    "推理步骤 2: 结合上下文事件进行关联分析。在温度飙升前（09:18），厨房灶具被开启；在温度异常期间（12:26-12:40），厨房窗户传感器状态变为 False（打开）。虽然窗户打开可能有助于散热，但无法解释为何温度会升至接近金属熔点的程度，除非发生了剧烈的燃烧或设备故障导致局部过热。",
    "推理步骤 3: 排除误报并确认威胁等级。其他房间（如客厅、卧室）的温度读数均在 25°C 左右波动，符合夏季室温特征，证明温度传感器本身未完全损坏（漂移），而是检测到了真实的极端热源。如此高的温度若持续，极大概率会导致烟雾报警器触发甚至引燃周围可燃物，构成即时火灾风险。"

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。

  "threat_type": "actuator_stuck",
  "threat_description": "灯的 OnOff 与 Level 矛盾",
  "reasoning": [
    "推理步骤1: 同一时刻 OnOff=False 但亮度非零",

Rejected response:
```json
{

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 living_room_light_1 状态正常，无异常行为或安全威胁。",
  "reasoning": [
    "推理步骤 1: 检查目标设备日志，发现 living_room_light_1 在 20:10:00 和 20:12:00 两次执行了关闭操作 (OnOff.OnOff = False)，且亮度设置为 180 (约 60%)，这是典型的用户手动调节或自动化场景（如观影模式）下的正常行为，非故障表现。",
    "推理步骤 2: 分析上下文环境，日志显示该时间段内 (17:44 - 22:40) 入户门、玄关及客厅多次检测到人员活动 (Occupancy = 1)，表明家庭处于活跃居住状态，设备响应符合住户习惯。",
    "推理步骤 3: 排查关联风险，虽然厨房温度传感器读数较低（约 22-23°C），但结合洗碗机启动记录及整体环境温度趋势，属于夏季晚间正常室温范围；未发现烟雾报警、漏水或门窗非法开启等异常事件。"
  ],
  "key_evidence": [
    "living_room_light_1 在有人活动的背景下进行了正常的开关/调光操作。",
    "全屋多房间 occupancy_sensor 持续报告有人存在，排除了无人看管导致的误报可能。",

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

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_description": "卧室温度传感器读数出现异常跳变（从21.8°C骤降至21.5°C以下并持续下降），且与客厅、厨房等其他区域温度变化趋势不一致，疑似传感器故障或电池电量不足导致的数据漂移。",
  "reasoning": [
    "1. 分析温度数据趋势：在19:00至20:40期间，卧室温度传感器读数从21.81°C缓慢下降至21.60°C，这符合夜间环境温度自然降低的规律。然而，在20:40之后，读数变为21.57°C，随后在21:20降至21.51°C，21:45降至21.50°C，22:05降至21.47°C。虽然数值仍在合理范围内，但结合其他房间来看存在异常。",
    "2. 对比跨房间数据一致性：在同一时间段内，客厅温度从22.99°C降至22.44°C，厨房温度从22.94°C降至22.47°C。通常卧室与客厅/厨房的温度差异不会如此显著地反向或独立波动，除非有独立的空调控制。日志中未显示卧室空调开启，且卧室窗帘在20:40被打开（CurrentPositionLiftPercent100ths = 10000，即100%打开），理论上应引入室外热量或保持室内平衡，但卧室温度却呈现持续微弱下降趋势，与其他房间趋于一致或略高的环境不符。",
    "3. 识别设备行为模式：Matter协议中的TemperatureMeasurement.MeasuredValue通常以厘度（centi-degrees）为单位。观察卧室传感器数据，其变化幅度极小且在某些时间点（如21:45到22:05）几乎停滞或微降，而同一时刻其他房间传感器数据正常更新。这种‘孤立’的微小漂移且缺乏物理原因（如开窗后无升温反而降温）支持，高度指向传感器硬件故障、校准失效或电池电压不稳导致的读数错误。对于独居老人，错误的温度读数可能导致空调误判，引发健康风险。"

## 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1",
    "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。
