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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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",

  ],
  "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。

    "1. 核心证据：日志显示在 03:16:00，`kitchen_smoke_alarm` 的 `SmokeState` 变为 1（通常表示检测到烟雾/火警），同时 `living_room_smoke_alarm` 的 `InterconnectSmokeAlarm` 变为 1，表明系统内其他烟雾探测器已联动响应。",
    "2. 状态确认：随后在 03:17:00，`living_room_smoke_alarm` 的 `ExpressedState` 变为 1，进一步确认了报警状态的持续和表达。",
    "3. 排除误报可能性：虽然凌晨 3 点属于深夜，但所有房间的运动传感器（Occupancy）均显示为 0，说明家中无人。这排除了因住户烹饪忘记关火导致的“未看管烹饪”场景（通常伴随人员活动），更倾向于设备故障、电气短路或外部因素引发的真实火情或误报。鉴于烟雾报警的高优先级，必须视为潜在的真实威胁处理。"

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
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",

    "1. 关键告警触发：日志显示在 2026-08-13T03:16:00，`kitchen_smoke_alarm` 的 `SmokeState` 变为 1（报警状态），同时 `living_room_smoke_alarm` 的 `InterconnectSmokeAlarm` 和 `ExpressedState` 也变为 1，表明系统已检测到烟雾并进行了联动广播。",
    "2. 温度异常趋势分析：从 01:20 到 04:55，所有房间的温度传感器读数均呈现明显的、持续的上升趋势。例如，客厅温度从 2298 (22.98°C) 升至 2441 (24.41°C)，厨房温度从 2334 (23.34°C) 升至 2411 (24.11°C)。虽然绝对值仍在舒适范围内，但在凌晨无人活动（Occupancy=0）的情况下，全屋温度同步且持续上升是不正常的，通常暗示供暖系统故障、门窗关闭导致的热量积聚，或者更严重的——火源产生的热量。",
    "3. 排除误报可能性：由于多个房间温度同步上升，且伴随烟雾报警，这不太可能是单个传感器的漂移或故障（sensor_drift）。如果是单纯的传感器故障，通常不会触发烟雾报警器的物理/化学感应机制。结合时间（凌晨3点，住户熟睡），这是最高优先级的安全威胁。"

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
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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": "厨房灶具关闭后温度传感器读数异常飙升，随后迅速回落，疑似发生干烧或局部高温事件，存在火灾隐患。",
  "reasoning": [
    "1. 识别关键时间窗口：在 19:20 左右，厨房灶具 (kitchen_cook_surface) 状态变为 False (关闭)，表明烹饪行为结束。",
    "2. 分析温度异常数据：在灶具关闭后的短时间内（19:25 - 19:35），厨房温度传感器 (kitchen_temp_sensor) 的读数从正常的 ~228°C (Matter协议通常以0.01度为单位，即22.8°C) 急剧飙升至 3050 (30.5°C) 和 3220 (32.2°C)。虽然绝对数值看似不高，但在短短10分钟内上升近10度且发生在热源刚熄灭时，符合余热积聚或局部热点的特征。",
    "3. 排除正常干扰并确认风险：19:24:30 厨房窗户传感器显示为 False (关闭)，排除了开窗散热导致温度骤降的可能；同时，烟雾报警器在此时段未触发报警，说明可能尚未产生大量烟雾，但高温本身已构成火灾前兆（如锅具干烧后余温过高引燃周边物品）。随后的温度回落（20:05回到22.6°C）可能是自然冷却或通风所致，但中间的高温峰值是明确的异常信号。"
