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。

  "reasoning": [
    "1. 分析关键事件序列：在 09:10:00 至 09:12:00 之间，客厅窗帘执行了两次开合操作（CurrentPositionLiftPercent100ths = 0），同时窗户接触传感器在 09:10:00 显示为 True (Closed)，但在 09:12:00 变为 False (Open)。",
    "2. 结合物理逻辑判断：通常智能窗帘关闭时（位置0%），如果窗帘盒设计合理，不应触发窗户接触传感器报警（即不应显示为打开）。然而日志显示窗帘关闭的同时/之后，接触传感器报告了“打开”状态。",
    "3. 排除人为入侵可能：此时段（上午9点）卧室和厨房均有人员活动迹象（Occupancy=1），且入户门未开启，无其他异常入侵特征。这种短暂的、与设备动作同步的状态翻转，更符合传感器安装松动、磁铁错位或窗帘轨道干涉导致的信号抖动。",
    "4. 综合评估：虽然温度数据正常，但针对重点关注的窗户安全设备，其状态变化不符合正常的‘人-窗’交互逻辑（即人不在场时窗户保持关闭，或人离开后窗户被手动打开），而是与自动化设备动作冲突，判定为传感器硬件或安装层面的故障。"

  "recommended_actions": [
    "检查客厅窗户接触传感器的安装位置，确认窗帘电机运行时是否撞击到传感器或其磁铁部件。",

    "推理步骤 2: 关键异常发生在 09:10:00。此时日志记录显示客厅窗户位置 (living_room_window) 为 0%（关闭），但仅 2 分钟后 (09:12:00)，窗户接触传感器 (living_room_window_contact) 的状态突然从 True 变为 False。结合上下文，这极可能意味着窗户被从外部强行推开，导致传感器逻辑翻转或物理触发，而系统未能及时响应这一变化。",
    "推理步骤 3: 综合行为模式，住户在早晨 (06:32-08:55) 有正常的卫生间和卧室活动记录，但在 09:00 左右卧室 occupancy 再次变为 1 后，紧接着发生了窗户异常开启事件。考虑到前门在 07:19 已被打开过，若住户当时并未完全离开或处于非正常状态，那么 09:10 的窗户异常配合之前的开门记录，强烈暗示了有人利用前门进入后，试图通过窗户通风或逃离，或者是入侵者正在屋内活动。特别是窗户传感器在‘关闭’状态下瞬间变为‘打开’，符合暴力破窗或推窗的特征。",
    "推理步骤 4: 尽管后续温度数据波动较大（可能是空调或阳光影响），但核心的安全设备序列（开门 -> 锁状态变更 -> 窗户异常触发）构成了完整的入侵证据链。"

## 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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "sensor_drift",
  "threat_description": "相邻房间温度读数差异突然增大",
  "reasoning": [
    "推理步骤1: 初始两房间读数相近",
    "推理步骤2: 后续只有一侧突增",
    "推理步骤3: 差值异常扩大不符合同户环境"
  ],
  "key_evidence": [
    "初始两房间读数相近",
    "后续只有一侧突增",
    "差值异常扩大不符合同户环境"
  ],
  "recommended_actions": [
    "判断为传感器漂移或局部测量故障。"
  ]
}

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "这些变化仍可视为正常波动。",
  "reasoning": [
    "推理步骤1: 没有看到必须报警的直接证据。"
  ],
  "key_evidence": [

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。

```json

  "threat_description": "客厅温度传感器出现异常跳变，读数瞬间飙升至29.2°C-29.6°C后迅速回落至正常范围（约24-25°C），疑似传感器故障或数据上报错误。",
  "reasoning": [
    "1. 分析目标设备：重点关注 living_room_temp_sensor 的温度读数变化。",
    "2. 识别异常模式：在 13:15、13:35 和 13:55 三个时间点，该传感器的 MeasuredValue 分别突变为 2920 (29.2°C)、2940 (29.4°C) 和 2960 (29.6°C)。",
    "3. 对比环境背景：同一时间段内，其他房间（如厨房、卧室）的温度传感器读数均在 23°C-25°C 的正常范围内波动，且客厅空调已开启（13:00 OnOff=True），通常会导致室温下降而非剧烈上升。",
    "4. 验证持续性：异常读数仅持续了约10-15分钟即恢复正常（例如13:15报29.2°C，13:20即恢复为25.04°C），这种瞬时尖峰不符合物理热惯性规律，也不符合老人独居的常规活动导致的缓慢温升。",
    "5. 排除误报：虽然13:00开启了空调，但空调启动初期若门窗关闭，室温不会瞬间飙升近5度；且后续读数迅速回归基准线，排除了火灾等导致持续高温的风险。"

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
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: ..."
  ],

    "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": true,
  "confidence": "high",

  "threat_description": "厨房温度传感器出现数据丢失（None）及读数异常波动，疑似硬件故障或通信中断。",
  "reasoning": [
    "1. 分析重点设备日志：虽然任务指定关注阳台洗衣机，但提供的日志片段中并未包含阳台洗衣机的状态变化（如启动、停止、漏水等），仅包含其他房间的温度和 occupancy 数据。因此无法基于洗衣机判断异常。",
    "2. 检查其他关键传感器数据：在 07:11:10，厨房温度传感器（kitchen_temp_sensor）的 `TemperatureMeasurement.MeasuredValue` 变为 `None`。在智能家居系统中，温度传感器突然返回空值通常意味着设备掉线、电池耗尽或内部电路故障。",
    "3. 观察后续数据恢复情况：该传感器在 07:30:00 恢复了读数（2522），但在 13:30:00 附近，读数从 2492 骤降至 2481，且随后日志截止。结合之前的 `None` 事件，这种间歇性的数据丢失和可能的读数跳变符合传感器硬件不稳定或通信模块故障的特征。",
    "4. 排除环境因素：同一时间段内，客厅、主卧、次卧的温度传感器读数均在 24-25°C 之间平稳变化，符合夏季室内正常温度范围。厨房作为热源区域，温度通常略高或波动较大，但不会导致传感器直接返回 `None`。因此，判定为设备自身问题而非环境极端变化。"

    "日志中未检测到阳台洗衣机（balcony_laundry_washer）的任何 OperationalState 变化，无法评估其健康状态。"
  ],
  "recommended_actions": [
    "检查厨房温度传感器的网络连接状态，尝试重启设备或重新配网。",
    "若问题持续，建议更换厨房温度传感器，以确保持续的环境监控能力。",
    "由于任务重点关注阳台洗衣机，请单独检查阳台区域的网络覆盖及洗衣机本身的运行日志，当前日志未提供相关证据。"

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
{

  "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。

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。
