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1",
    "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: 分析时间线发现，用户在 2026-08-16T19:00:00 开启了灶具 (kitchen_cook_surface)，随后在 19:20:00 关闭。在此期间，正常的厨房温度应随加热上升并在关闭后缓慢下降。",
    "推理步骤 2: 观察日志发现，在 19:25:00 和 19:35:00，厨房温度传感器报告了异常高的数值 (3050 和 3220)。考虑到其他房间（如卧室约 2180-2200，客厅约 2270-2280）的温度读数均在合理范围（假设单位为 0.1°C，即室温约 22°C），3000+ 的读数明显不符合物理规律，极可能是传感器故障或通信错误导致的乱码/溢出。",
    "推理步骤 3: 这种传感器数据的剧烈波动和不可信读数属于典型的 sensor_malfunction。如果依赖此数据进行自动化报警（如高温触发烟雾报警器联动），可能导致误报；反之，若传感器因故障未能正确上报真实的高温，则存在漏报火灾的风险。此外，日志中还存在多次 `MeasuredValue = None` 的情况，进一步证实了该传感器状态不稳定。"
  ],
  "key_evidence": [

    "同一时间段内，卧室和客厅温度传感器读数稳定且相互接近，排除了全局环境突变的可能性"
  ],
  "recommended_actions": [
    "立即检查并更换厨房温度传感器硬件，或重启该设备以排除临时性通信故障。",
    "在修复前，建议用户手动关注厨房区域，避免完全依赖自动化的高温预警系统。",

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
{
  "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",

  "reasoning": [
    "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。"

## 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": "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
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "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。"

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

  "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。
