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。

    "2. 温度数据合理性分析：厨房温度传感器数值在 2467-2559 之间波动。根据 Matter 协议标准，TemperatureMeasurement.MeasuredValue 的单位是厘氏度（cHmdegC，即 0.01°C）。因此，2467 代表 24.67°C，2559 代表 25.59°C。这些数值处于舒适的室内环境温度范围内，无异常高温（如火灾导致的急剧升温）或低温故障。",
    "3. 人员活动与门锁逻辑一致性：07:35 左右，入户门经历了解锁、开门、关门、上锁的完整流程，且此时卧室和卫生间有短暂的人员占用信号，符合住户早晨出门或整理后外出的行为模式。后续时间段内，虽然部分房间（如客厅） occupancy 为 0，但卧室仍有活动迹象，整体行为符合正常居家节奏，无长时间无人却发生异常事件的情况。"

## 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",

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。

    "2. 厨房温度传感器读数从 12:50 的 25.09°C 缓慢下降至 15:45 的 24.07°C。这种线性且平缓的温度变化符合夏季午后室内自然降温或空调调节后的环境特征，不存在因火灾或设备故障导致的急剧升温。",
    "3. 运动传感器（entrance, dining_room, kids_room, master_bedroom）在 13:27 至 15:27 期间频繁触发，表明家中有多名住户在不同房间活动。这种多点位的人员流动与家庭日常起居（如午休后起床、准备晚餐前活动等）相符，未发现长时间无人活动的异常静默或非法入侵迹象。"

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
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",

    "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。

  "confidence": "medium",
  "threat_type": "none",

    "推理步骤 1: 时间线分析显示，用户在 09:18 首次开启灶具，并在 09:36 关闭；随后在 12:05 再次开启灶具。",
    "推理步骤 2: 关键异常发生在 12:05 之后。灶具于 12:05 开启，但在 12:10 时，客厅运动传感器检测到有人（Occupancy=1），而卧室也检测到有人。然而，从 11:46 到 12:16 期间，厨房区域本身没有明确的‘有人’活动记录（如厨房灯未开，且无厨房占用报告），或者更严重的是，用户可能在操作后离开了厨房区域。",
    "推理步骤 3: 最致命的证据是温度数据。在 12:05 开启灶具后，厨房温度传感器读数从正常的 ~2700K (约 24°C) 急剧飙升至 2920K (约 26.8°C) 甚至更高（之前曾达到 2936K）。这种在高温烹饪设备开启时的快速升温，结合可能的无人看管（Unattended Cooking）场景，是典型的火灾隐患前兆。此外，11:47 出现的 'None' 温度读数可能暗示传感器故障或信号中断，增加了不确定性，但随后的持续高温读数确认了热积聚现象。",
    "推理步骤 4: 综合判断，灶具开启后温度持续攀升且未见及时关闭或降温迹象，符合‘无人看管烹饪’导致的火灾风险特征。"

## 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。

## 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：

  "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 1: 日志显示在 2026-07-11T11:06:30 和 12:05:00 有明确的灶具开启事件 (OnOff.OnOff = True)，表明厨房正在进行正常的烹饪活动。",
    "推理步骤 2: 在 11:41:00 至 12:05:00 期间，厨房温度传感器读数稳定在 25°C 左右，符合室温预期；但在 12:12:00 突然飙升至 29.2°C (2920 mK)，随后在 12:15:00 又回落至 25.26°C。这种在短时间内无外部热源介入下的剧烈波动不符合物理规律。",
    "推理步骤 3: 最关键的是，在 11:23:00 该传感器报告了 `MeasuredValue = None`，这通常意味着设备离线、电池耗尽、信号干扰或硬件损坏。对于一个独居老人家庭，烟雾/温度报警器的失效是严重的安全隐患，可能导致真实火灾发生时无法报警。",
    "推理步骤 4: 虽然 12:12:00 的 2920 读数可能让人联想到高温，但考虑到前后数值的稳定性以及之前的 `None` 状态，更可能是传感器校准错误、固件 Bug 或瞬时通信丢包导致的脏数据，而非真实的火灾升温（如果是火灾，温度应持续上升且伴随其他传感器如烟雾报警器的触发）。"
