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",

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",

    "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。

Chosen response:
{
  "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。"

Rejected response:

  "threat_type": "sensor_malfunction",
  "threat_description": "卧室温度传感器在夜间出现严重的数据跳变和逻辑矛盾，显示设备可能故障或被干扰。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-07-17T17:00:00 时，卧室温度传感器报告数值为 2580 (约 25.8°C)，而客厅仅为 25.2°C，此时卧室无人且无加热设备运行，该读数相对于随后几小时的趋势显得异常偏高。",
    "推理步骤 2: 紧接着在 2026-07-17T17:05:00，同一传感器数值瞬间从 2580 暴跌至 2254 (约 22.5°C)，并在随后的 17:30-18:30 期间持续下降至 2200 (约 22.0°C)。这种在短时间内（5 分钟内）发生超过 3 度的剧烈反向跳变，不符合热力学规律，排除了环境温度自然变化的可能性。",
    "推理步骤 3: 结合上下文，17:00 的 2580 读数极可能是传感器通信错误、固件 Bug 导致的瞬时乱码，或者是有人试图通过物理接触/红外干扰篡改数据；随后的快速冷却曲线更像是系统重置或传感器重新校准后的正常低温读数，而非真实的房间降温过程。这种‘先暴涨后骤降’的模式是典型的传感器故障特征。"

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",

    "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. 确认任务完成：在 11:00 时，洗衣机的 OperationalState 变为 0（空闲/停止），符合从 10:00 开始、持续约 1 小时的典型洗衣周期逻辑。",
    "3. 排除其他风险：虽然日志中包含大量温度传感器数据，但所有读数均在合理范围内（约 24-25°C），且未检测到漏水传感器报警、烟雾报警或门锁异常。 occupancy 传感器均显示为 0，表明此时家中无人或人员未在关键区域活动，这与白天洗衣机自动运行的场景相符，不存在因无人看管导致的火灾或漏水风险（因为设备本身工作正常）。"

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
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。

    "2. **用户行为模式匹配**：06:51 入户门解锁并打开，随后玄关和厨房传感器陆续检测到人员活动（Occupancy=1），表明老人已起床并开始日常活动。08:37 门锁手动上锁，符合离家或短暂外出后返回/再次锁门的习惯。",
    "3. **重点设备状态解析**：09:10 客厅窗帘开启至50%位置，同时窗户接触传感器由False变为True（表示窗户被推开）。在室温持续升高（25.5°C）的背景下，开窗通风是合理的降温行为，并非异常入侵或设备误报。",
    "4. **排除异常风险**：虽然厨房温度传感器在10:51出现一次 `None` 值，但随后立即恢复正常读数，且无烟雾报警或漏水警报，推测为瞬时通信丢包而非设备故障。整体活动轨迹连贯，无长时间静止（跌倒风险低）或夜间异常活动。"

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。

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: 即使排除数据丢失，该传感器的读数也完全不符合物理规律。从凌晨到上午，厨房温度从约 23°C (2396 mK) 线性上升至超过 25.5°C (2550 mK)，且在无人操作的情况下持续攀升，这种非自然的快速升温曲线极可能是传感器漂移或损坏导致的误报。",
    "推理步骤 3: 结合其他房间的温度传感器数据（如 living_room 和 master_bedroom），虽然它们也有上升趋势，但厨房作为热源集中区，其温度变化幅度过大且伴随数据丢包，进一步证实了该特定设备存在健康隐患，而非单纯的环境过热。"

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。

    "1. 人员活动模式分析：从14:15开始，客厅、卧室、厨房、玄关等多个区域的运动传感器持续触发（Occupancy=1），表明住户在家中进行日常活动。特别是在17:28至22:03期间，玄关运动传感器频繁触发，结合20:50的入户门手动开锁记录，符合老人晚间外出散步或处理事务后回家的正常行为模式。",
    "2. 照明与电器控制逻辑：20:10卧室灯开启并调光，随后在20:50关闭，20:33卫生间灯开启，这些操作时间点和持续时间（如洗澡、睡前准备）符合老年人的生活习惯，无异常长亮或频繁误触现象。",
    "3. 环境数据稳定性：各房间温度传感器读数随时间缓慢变化（如客厅从23.6°C降至22.4°C左右），符合夏季傍晚气温自然下降的趋势，未发现传感器漂移或故障导致的跳变。",
    "4. 安全设备状态：日志中未出现烟雾报警器、一氧化碳报警器或漏水传感器的报警事件，门锁操作均为Manual（手动），无暴力破解或异常远程访问迹象。"
