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: 虽然夏季白天室温升高是可能的，但仅 10 小时内升温超过 2.5°C 对于有空调设备的房间来说速度过快且幅度过大，尤其是在住户大部分时间处于卧室或厨房的情况下。",
    "推理步骤 3: 对比同一时间段内的卧室温度传感器数据（约 23-24°C）和厨房温度传感器数据（约 24-25°C），客厅温度明显高于其他区域且呈现不合理的线性上升趋势，这不符合自然热力学规律，极大概率是传感器硬件故障、校准失效或信号漂移（Sensor Drift）导致的误读。",
    "推理步骤 4: 若该读数被系统判定为真实高温并触发警报，将给独居老人造成不必要的恐慌；若系统依赖此数据进行自动化控制（如关闭空调），可能导致室内实际过热，存在安全隐患。"

## 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",

}
```

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 1: 分析时间线发现，在 2026-08-27T14:00:00 时，卧室窗户 (bedroom_window) 被报告为完全关闭 (CurrentPositionLiftPercent100ths = 0)，此时卧室温度传感器读数从之前的 2333 mK (约 23.3°C) 瞬间跳变为 2550 mK (约 25.5°C)。",
    "推理步骤 2: 随后在 14:10:00 至 14:15:00 期间，该传感器读数在 2470 mK 和 2362 mK 之间剧烈震荡，这种高频大幅波动不符合热惯性原理，表明传感器可能受到干扰或内部故障。",
    "推理步骤 3: 最关键的是，从 14:50:00 开始，卧室温度读数持续下降至 2228 mK (约 22.3°C)，而与此同时，厨房灶具 (kitchen_cook_surface) 在 11:06:00 开启后一直有人使用（厨房 occupancy 持续为 1），且客厅温度维持在正常范围 (23-25°C)。如果卧室真的像早期读数显示的那么热，或者像后期读数显示的那么冷，都会与独居老人的生活场景产生矛盾。特别是 14:00 的突增和随后的震荡，极大概率是传感器硬件故障、校准丢失或通信丢包导致的乱码，而非真实环境温度变化。",
    "推理步骤 4: 考虑到住户为独居老人，错误的温度数据可能导致空调系统误判（例如在高温报警时实际很冷，或在需要加热时停止工作），进而引发健康风险或能源浪费，因此判定为高置信度的传感器故障。"

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
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",

  ],
  "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。

Chosen response:

  "threat_description": "卧室温度传感器在 14:00 出现严重数据跳变，且后续读数持续异常偏低，疑似设备故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，卧室温度传感器 (bedroom_temp_sensor) 在 2026-07-14T13:55:00 报告温度为 2300 (即 23.0°C)，但在同一分钟后的 14:00:00 突然跳变为 2430 (24.3°C)，随后在 14:05:00 又剧烈波动至 2550 (25.5°C)。这种在短时间内（几分钟内）发生超过 2°C 的剧烈反向波动不符合热力学规律，排除了正常环境变化。",
    "推理步骤 2: 对比客厅温度传感器 (living_room_temp_sensor) 的数据，其读数在 14:00 左右稳定在 2465 (24.65°C) 附近，与卧室之前的趋势一致，说明房间整体环境温度并未发生如此剧烈的突变，进一步证实卧室传感器的读数不可信。",
    "推理步骤 3: 从 14:10 开始，卧室温度读数迅速下降并持续走低（14:10 为 2470，14:20 降至 2362，15:00 降至 2330，16:00 降至 2309），直到傍晚 18:00 后降至 2200 以下。虽然夏季夜间降温合理，但结合上午的剧烈跳变和下午的快速非自然下降，该传感器极可能已损坏、电池接触不良或被遮挡导致测量失准。",
    "推理步骤 4: 尽管空调在 18:05 开启，但传感器未能正确反映开机后的升温过程（通常应缓慢回升），反而继续显示低温，这符合传感器硬件故障的特征，而非正常的制冷/制热响应延迟。"

    "同期 living_room_temp_sensor 读数平稳（约 2465°C），证明环境未发生对应变化，排除真实温度骤变的可能。",
    "14:10 之后卧室温度读数呈断崖式下跌（从 2470 降至 2200+），且与空调开启时间不匹配，显示传感器逻辑混乱。"

  "recommended_actions": [

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：

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": [
    "推理步骤 1: 在 19:47:00，日志显示厨房灶具 (kitchen_cook_surface) 状态变为 False (关闭)，表明烹饪活动结束。",
    "推理步骤 2: 紧接着在 19:47:30，厨房窗户传感器 (kitchen_window_contact) 状态变为 False (打开)，这通常是用户试图通风散热的正常反应。",
    "推理步骤 3: 然而，在窗户打开后的短时间内 (19:50:00)，厨房温度传感器读数飙升至 2590 (mK)，换算约为 26.9°C。考虑到之前该区域温度在 23-24°C 左右，且此时无人操作（无人员进入事件记录），这种温升极不寻常。",
    "推理步骤 4: 结合时间线，灶具刚关闭，若灶具内部元件未完全冷却、发生自燃或存在燃气泄漏导致局部过热，而窗户打开可能加速了热量积聚或改变了气流导致传感器误报，但最危险的假设是发生了未被察觉的火灾前兆或设备故障导致的持续发热。",
    "推理步骤 5: 虽然温度数值本身不算极高（对于火灾而言），但在家庭环境中，灶具关闭后短时间内出现不明原因的显著温升，尤其是伴随开窗行为，属于高风险的安全异常模式，不能简单归因为环境温度变化。"

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。

    "2. **人员活动模式分析**：06:37 卧室有人，07:00 门锁手动开启（Manual Lock Operation），随后玄关、厨房、卫生间均有短暂的人体存在信号（Occupancy=1/0 切换），表明老人已起床并进行了洗漱、准备早餐等日常活动。08:26 门锁状态变为 2（Locked），符合离家或反锁的正常行为。",
    "3. **重点设备状态验证**：任务关注的 `living_room_window` 在 09:10 被打开至 50%（CurrentPositionLiftPercent100ths = 5000），同时窗户接触传感器 `living_room_window_contact` 状态变为 False（表示窗户处于非完全闭合状态，通常 False 代表 Open/Unlatched，True 代表 Closed/Latched，或者反之，但关键在于两者状态联动且伴随人员在场）。09:20 接触传感器变回 True，可能意味着窗户被重新关闭或传感器逻辑判定为闭合。整个过程有客厅 occupancy 传感器支持（09:11, 09:36 均为 Occupancy=1），说明是住户主动操作，而非非法入侵。",
    "4. **排除异常风险**：没有发现烟雾报警触发、漏水检测报警、一氧化碳风险或长时间无人活动的健康警报。所有设备响应时间正常，无 stuck 或 malfunction 特征。"

## 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。

    "推理步骤 3: 更关键的异常发生在 13:55:00，同一秒内传感器连续上报了两个截然不同的数值：2469 和 2610。这种在同一时间戳产生冲突读数的现象是典型的传感器硬件故障、通信丢包重传错误或被恶意篡改的特征，而非真实的环境变化。"
