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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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。

  "reasoning": [
    "推理步骤 1: 日志显示在 2026-07-01T18:06:00 时，厨房温度传感器报告了 2960 (约 29.6°C)，随后在 18:13:00 和 19:31:00 连续两次返回 None (无数据)。",
    "推理步骤 2: 结合上下文，18:12:00 厨房灯开启，且此前有灶具活动迹象（虽然未直接看到灶具状态变化，但温度波动剧烈），此时传感器突然断连或报错，不符合正常的热惯性变化规律。",
    "推理步骤 3: 这种间歇性的数据丢失（None）以及极端的数值跳变（从 ~23°C 瞬间跳到 29.6°C 再恢复正常范围），强烈暗示传感器硬件故障、连接中断或被物理遮挡/损坏，而非真实的环境温度变化。"

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "多个房间温度同时异常上升",
  "reasoning": [
    "推理步骤1: 客厅和卧室温度同时异常上升",
    "推理步骤2: 厨房也同步升温",
    "推理步骤3: 不是单一热源可解释的局部变化"
  ],
  "key_evidence": [
    "客厅和卧室温度同时异常上升",

  "threat_description": "厨房和客厅温度传感器在傍晚时段出现严重的数据跳变（漂移），且与周围房间及物理环境逻辑不符，疑似传感器故障或受到强电磁干扰。",
  "reasoning": [
    "推理步骤 1: 数据单位分析。日志中的温度值（如 2273, 2840）明显超出了常规摄氏度范围，结合 Matter 协议常见实现，这些数值极有可能是以 0.1°C 为单位的原始读数（即实际温度为 22.73°C - 28.40°C）。",
    "推理步骤 2: 异常模式识别。在 18:02 至 18:06 期间，living_room_temp_sensor 和 kitchen_temp_sensor 报告了高达 2840 (28.4°C) 和 2960 (29.6°C) 的极端高温值。然而，同一时间点的 master_bedroom、second_bedroom 和 bathroom 的温度读数稳定在 2300-2350 (23.0-23.5°C) 之间，且所有运动传感器均显示无人活动（Occupancy=0）。",
    "推理步骤 3: 逻辑矛盾排除。如果发生真实火灾或高温事件，卧室和卫生间的温度应同步上升，且会有人员活动记录。由于其他区域温度正常且无人员活动，厨房和客厅的瞬时高温读数无法用真实热源解释，判定为传感器硬件故障、校准丢失或通信数据包损坏导致的读数漂移（Sensor Drift/Malfunction）。",
    "推理步骤 4: 恢复情况。异常发生后约 2 分钟（18:06 之后），两个传感器的读数迅速回落并稳定在与其他房间一致的 23°C 左右水平，进一步证实这是瞬时的设备故障而非持续的环境变化。"

    "在温度异常飙升期间，所有房间的运动传感器（occupancy_sensor）均报告 Occupancy = 0，且无其他热相关设备（如空调、灶具）的状态变更记录。",
    "异常读数在 18:06 后迅速恢复正常，表现出典型的传感器瞬时故障特征。"
  ],
  "recommended_actions": [
    "立即检查厨房和客厅的温度传感器硬件连接及供电状态，确认是否存在接触不良或过热损坏。",
    "建议重置这两个温度传感器，并在 Matter 网络中重新校准其基准温度。",
    "暂时将这两个传感器标记为“不可靠”，依赖其他房间的温度数据进行全屋温控决策，直到故障修复。",
    "检查该时间段内是否有强电磁干扰源（如大功率电器启动）导致无线信号噪声，但鉴于数值的极端性，硬件故障可能性更大。"

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "灶具关闭后温度仍持续上升",
  "reasoning": [
    "推理步骤1: 灶具已关闭",
    "推理步骤2: 厨房温度没有回落反而继续升高",
    "推理步骤3: 升温趋势持续超过一个采样点"
  ],
  "key_evidence": [
    "灶具已关闭",
    "厨房温度没有回落反而继续升高",

  ],

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在灶具关闭后出现严重数据漂移和跳变，导致读数远超物理可能范围（>30°C），疑似传感器故障或校准错误。",
  "reasoning": [
    "1. 时间线分析：2026-07-11T19:00:00 厨房灶具 (kitchen_cook_surface) 被开启，随后温度从约 23°C 缓慢上升至 28°C (2281)，符合正常烹饪加热逻辑。",
    "2. 异常触发点：2026-07-11T19:20:00 灶具被关闭 (OnOff = False)。按照热力学规律，灶具关闭后温度应开始下降或维持高位一段时间，但不应瞬间剧烈波动。",
    "3. 数据异常特征：在灶具关闭后的短时间内 (19:25:00 - 19:40:00)，温度传感器报告了多次极端数值 (3050, 3220)。考虑到 Matter 协议中温度通常以 0.1°C 为单位，3050 代表 305.0°C，这在家庭厨房环境中是物理上不可能的（会导致火灾报警立即触发且设备损坏）。",
    "4. 排除误报：虽然存在偶发的单点跳变 (如 19:25:00 的 3050)，但紧接着在 19:30:00 又出现了另一个更高的跳变 (3220)，且周围其他房间的温度传感器数据稳定正常，排除了环境温度突变的可能性。这种非单调、大幅度的随机跳变是典型的传感器硬件故障或固件逻辑错误。",
    "5. 风险评估：尽管烟雾报警器未在此日志片段中报警，但如此高的虚假读数可能导致系统误判为火灾风险而切断电源，或者掩盖真实的温度变化趋势，属于严重的传感器失效 (Sensor Malfunction)。"
  ],
  "key_evidence": [

    "2026-07-11T19:25:00 温度传感器报告 MeasuredValue = 3050 (即 305.0°C)",
    "2026-07-11T19:35:00 温度传感器再次报告 MeasuredValue = 3220 (即 322.0°C)"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理连接及供电情况，确认是否松动或受潮。",
    "联系设备制造商进行固件更新或申请更换该传感器，因为软件层面的校准无法修复此类极端跳变。",
    "在维修期间，建议人工定期目视检查灶具区域是否有过热迹象，并暂时依赖烟雾报警器作为主要监控手段。",
    "审查 Matter 设备日志配置，确保未来能捕获更细粒度的传感器健康状态指标（如信号强度、电池电压等）以便提前预警。"

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。

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。

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

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. 排除真实火灾或高浓度烟雾风险：如果存在真实的火灾或大量烹饪油烟，通常会触发 SmokeCoAlarm.AlarmState（声光报警），但日志中未出现 AlarmState 的变化。此外，厨房温度传感器（kitchen_temp_sensor）的数据非常平稳，仅在 24.9°C - 25.5°C 之间微小波动，没有出现火灾或高温烹饪时常见的温度急剧上升现象。",
    "3. 结合住户活动模式判断：虽然早晨有人员活动（如门锁操作、运动传感器触发），但没有证据表明有人在厨房进行产生大量烟雾的剧烈烹饪活动。ContaminationState 的线性递增更倾向于灰尘积累、传感器老化或硬件故障，而非突发的外部烟雾事件。因此，判定为传感器自身功能异常。"

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。

  "reasoning": [

    "3. 排除环境干扰：在同一时间段内，其他房间（如卧室、客厅）的运动传感器活跃，表明住户在家且正常活动，但并未提及全屋高温。更重要的是，在 19:35 之后，温度读数迅速恢复正常范围（2274-2288），这种‘尖峰-回落’的模式不符合自然散热曲线（通常缓慢下降），也不符合正常的室温波动。",
    "4. 结合独居老人背景：对于独居老人，灶具使用后未及时清理残留火源、油锅过热或传感器故障导致误报是主要风险。虽然最终温度未持续升高，但这种瞬间的高温尖峰极有可能是灶具附近发生了短暂的剧烈放热（如余烬复燃、油脂滴落燃烧）或传感器受到热源直接辐射导致的瞬时高读。考虑到安全原则，这被视为潜在的火灾风险信号。"
