## 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：

  "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",

    "3. 结合独居老人的背景，这种“灶具开启但无人在场”的情况极有可能是老人忘记关火或中途离开去处理其他事务，属于典型的无人看管烹饪场景。",

## 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",

  ],
  "recommended_actions": [

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": [
    "时间线分析：在 2026-07-02T14:00:00 洗碗机启动后，家庭内部活动正常。但在 16:22:02 发生关键事件序列。",
    "门锁状态异常：16:22:02 入户门传感器 (front_door_contact) 状态变为 False，表示门被打开。此时日志中未显示正常的开门授权操作（如用户主动解锁记录）。",
    "关联行为异常：紧随门打开之后（16:22:06），儿童房灯光突然开启。考虑到当时儿童房运动传感器显示有人（16:52:04 确认有人，但中间时段需结合上下文），更可疑的是，如果这是家庭成员回家，通常会先经过玄关/客厅，直接触发儿童房灯光且伴随无人看管下的洗碗机运行结束倒计时减少，存在非授权人员进入并试图寻找目标或干扰的风险。",
    "排除误报：虽然 16:12:33 和 16:47:03 有 entrance_occupancy=1 的记录，但这通常指门口区域有人移动。然而，16:22:02 的 contact_sensor=False 是明确的物理开门动作。结合随后儿童房灯光的突兀变化，这不符合常规的家庭作息模式（例如父母下班回家通常会先去客厅或主卧，而非直接开儿童房灯，除非家里有孩子且刚起床，但此时已是下午 4 点多，且之前 occupancy 显示稳定）。最合理的推断是有人通过某种方式（可能是钥匙、密码或技术开锁）打开了门，或者发生了尾随，并进入了室内。",
    "设备状态佐证：洗碗机在 16:00 仍有 5400 秒（90 分钟）倒计时，到 17:05 仅剩 5200 秒，说明机器一直在运行。如果入侵者进入时家中无人（除了可能正在睡觉的孩子，但儿童房灯开了），则构成了对居住安全的直接威胁。"

System:
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",
  "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: ...",

    "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。

  "threat_description": "厨房烟雾报警器触发，且全屋温度在凌晨时段呈现异常持续上升趋势，存在火灾或高温隐患。",
  "reasoning": [
    "1. 关键告警触发：日志显示在 2026-07-15T03:16:00，厨房烟雾报警器（kitchen_smoke_alarm）的 SmokeState 变为 1（报警状态），同时客厅烟雾报警器（living_room_smoke_alarm）的 InterconnectSmokeAlarm 和 ExpressedState 也变为 1，表明系统已检测到烟雾并联动报警。",
    "2. 温度异常趋势：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 23.11°C 升至 24.41°C，厨房从 23.32°C 升至 24.10°C（中间有波动但整体高位）。虽然绝对数值尚未达到极端高温，但在凌晨无人活动（Occupancy=0）的情况下，室内温度持续攀升是不正常的，通常暗示有热源未关闭或环境失控。",
    "3. 排除误报可能性：结合温度持续上升的趋势和烟雾报警的同时发生，这极大概率不是单纯的传感器故障或误报，而是真实的火情初期或过热现象。凌晨时段住户均处于睡眠状态（无 occupancy 信号），无法及时察觉危险。"
