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",

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。

  "reasoning": [
    "1. 识别到烹饪行为：19:00时厨房灯和灶具同时开启，表明住户开始做饭。",
    "2. 发现异常断电/离开迹象：19:20灶具关闭，但随后日志显示19:26再次出现灶具关闭状态（可能为重复上报或短暂重启），关键在于19:35温度传感器读数飙升至3220（约32.2°C），远高于之前的正常室温（~23°C）和刚开火时的升温速度。",
    "3. 确认无人看管：从19:20灶具关闭后，直到19:35高温记录期间，客厅运动传感器虽显示有人（19:35:14），但厨房区域无直接活动证据，且灶具已处于关闭状态。然而，更严重的信号是19:25-19:35之间温度的剧烈波动和最终的高值，这通常意味着余热积聚或小火未完全熄灭导致的持续加热，或者传感器本身故障。但结合'fire_risk'的严重性，必须假设最坏情况：即灶具并未真正安全关闭，或者残留热量导致局部过热。",
    "4. 综合判断：虽然灶具显示Off，但温度数据的异常峰值（3220）与正常环境温差过大，且发生在烹饪结束后不久，极有可能是因为灶具实际仍在释放热量（如燃气泄漏燃烧不完全、电磁炉散热异常或传感器被热源近距离烘烤）。考虑到智能家居安全原则，当检测到烹饪相关设备操作后伴随非正常的温度激增，应优先判定为火灾风险。"

  "reasoning": [
    "1. 分析时间线与设备状态：在19:20，厨房灶具(kitchen_cook_surface)被关闭(OnOff=False)。此时温度传感器读数为正常的22.78°C。",

    "3. 评估后续行为与恢复情况：紧接着在19:35，读数进一步升至32.20°C，但在19:40迅速回落至22.72°C，并在19:50稳定在22.67°C。这种‘尖峰’式的温度变化不符合正常烹饪加热后的自然冷却曲线（通常冷却较慢），也不符合环境温度变化的规律。",
    "4. 排除其他干扰因素：虽然19:33洗碗机启动，但洗碗机通常不会导致室温瞬间剧烈波动。更可能的解释是：灶具刚关闭时仍有极高表面温度，直接辐射或对流影响了近距离的温度传感器，或者传感器本身因靠近热源发生了短暂的测量漂移/故障。然而，考虑到Matter协议中温度传感器的精度和响应速度，如此剧烈的瞬时跳变且伴随灶具使用历史，首先应视为潜在的火灾隐患（如余烬未熄、线路短路发热）或传感器被遮挡/损坏导致的错误读数。鉴于安全优先原则，需标记为高风险。"

## 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

  "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 3: 排除误报可能性，该数值 (2960) 相对于之前的 23xx 系列读数发生了断崖式跳跃，不符合热力学规律，属于典型的传感器数据漂移、校准错误或通信丢包导致的乱码，而非真实火灾风险。"

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
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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",
    "厨房也同步升温",
    "不是单一热源可解释的局部变化"
  ],
  "recommended_actions": [
    "按全屋热异常处理，建议检查火源或电器过热。"

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在正常活动时段出现严重数据漂移和丢失，且卧室温度读数异常偏高，疑似传感器故障或受强干扰，存在误报火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-07-12T18:02:00 至 18:06:00 期间，住户处于活跃状态（厨房、入户门、客厅均有 occupancy=1），但厨房温度传感器读数从正常的 23xx (约 23°C) 瞬间跳变至 2840 (约 28.4°C)，随后在 18:06:00 再次跳变至 2960 (约 29.6°C)。这种在短时间内剧烈波动且远超物理可能性的数值变化，不符合烹饪升温的自然规律。",
    "推理步骤 2: 对比同一时间段的其他设备，卧室温度传感器在同一时刻也出现了异常飙升（从 2233 跳变至 2810），随后迅速回落。多个房间传感器同时出现非同步的极端数值跳变，强烈暗示是网络传输错误、传感器硬件故障或 Matter 协议下的数据包解析错误，而非真实的火灾事件。",
    "推理步骤 3: 关键证据在于 2026-07-12T17:22:00 厨房温度传感器报告了 `None` (数据丢失)，紧接着在 18:00 后出现乱码般的数值。结合独居老人场景，若系统误判为高温而触发警报，会造成不必要的恐慌；若不处理，可能导致真正的火灾隐患被掩盖或系统逻辑混乱。因此判定为传感器故障/数据漂移。"

  "key_evidence": [
    "2026-07-12T18:02:00 - 18:06:00 期间，厨房温度传感器数值从 ~23°C 瞬间跳变至 ~28-29°C，与周围环境和用户行为不符。",
    "2026-07-12T17:22:00 厨房温度传感器报告 `None`，显示通信中断或数据无效。",
    "2026-07-12T18:04:00 卧室温度传感器同步出现异常高值 (2810)，排除了单一设备局部过热导致的可能性。"
  ],
  "recommended_actions": [
    "立即通知住户或家属检查厨房和卧室的温度传感器是否工作正常，确认无真实火情。",
    "建议智能家居系统暂时屏蔽该传感器的报警功能，并安排技术人员上门校准或更换故障传感器。",
    "检查 Matter 网关日志，排查是否存在网络拥塞或固件 Bug 导致的数据包损坏。"
