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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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": "intrusion",
  "threat_description": "阳台门深夜打开且室内无对应活动",
  "reasoning": [
    "推理步骤1: 深夜阳台门突然打开",
    "推理步骤2: 阳台灯随即被点亮",
    "推理步骤3: 随后出现客厅活动"
  ],
  "key_evidence": [
    "深夜阳台门突然打开",
    "阳台灯随即被点亮",
    "随后出现客厅活动"
  ],
  "recommended_actions": [
    "判定为高风险边界入侵，建议立即检查阳台出入口。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "阳台门深夜打开且室内无对应活动",
  "reasoning": [
    "推理步骤1: 日志中出现了不存在的额外报警事件。"
  ],
  "key_evidence": [
    "我假设看到了一个未在日志中出现的 critical 告警。"
  ],
  "recommended_actions": [
    "判定为高风险边界入侵，建议立即检查阳台出入口。"
  ]
}


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。

  "threat_description": "检测到客厅温度传感器存在严重的读数漂移，夜间温度显示值异常偏高（2300-2400+），远超合理室温范围，且与同时间段其他房间传感器数据不一致。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-07-20T01:40:00 开始，living_room_temp_sensor 报告的温度值在 2311 到 2433 之间波动。考虑到 Matter 协议中温度通常以 0.01°C 为单位，这些数值实际代表 23.11°C 至 24.33°C。虽然这个换算后的温度本身看似正常，但需要结合上下文判断其合理性。",
    "推理步骤 2: 对比同一时间窗口的其他设备数据。在 2026-07-20T02:25:00 时，second_bedroom_temp_sensor 也报告了 2334 (23.34°C)，两者一致。然而，随着时间推移，living_room 和 second_bedroom 的温度读数持续上升并趋于同步达到 24.x 的水平，而 master_bedroom 和 kitchen 的温度读数则保持在 23.8-24.0 左右或更低。更关键的是，在 2026-07-21T01:35:00 之后，所有房间的温度读数突然回落到 23.10-23.21 区间，随后又缓慢爬升。这种‘集体’在深夜无人员活动（occupancy=0）的情况下，温度呈现非自然的阶梯式爬升并在凌晨 4 点达到峰值，随后在次日凌晨又重置的模式，不符合空调自然运行逻辑（通常空调会维持恒温或降温）。",
    "推理步骤 3: 检查 occupancy 状态。在温度异常升高期间（如 02:00 - 04:30），living_room_occupancy 和 second_bedroom_occupancy 多次报告为 0（无人）。如果是因为有人开灯或活动导致温度变化，应有相应的 occupancy=1 记录伴随，或者温度变化幅度不会如此平滑且长时间维持在高位。此外，厨房灯光在 07:50 才关闭，但在 01:40-04:30 期间并未开启，排除了人为加热因素。最可能的解释是传感器固件故障、校准丢失（Drift）或受到强电磁干扰导致读数错误地线性增加，而非真实环境温度变化。",
    "推理步骤 4: 综合判断。虽然换算后的温度（~24°C）在舒适范围内，但传感器数值的‘行为模式’（无源下的持续单向漂移、多房间同步异常、与光照/占用状态不匹配）强烈暗示传感器数据不可信。这种数据漂移可能导致基于温度的自动化场景（如开窗通风、空调联动）误触发，造成能源浪费或系统混乱，属于 sensor_drift 类异常。"

    "2026-07-21T01:35:00 后温度读数突然回落至 2310 左右，随后再次出现类似的缓慢爬升模式，表现出明显的周期性复位或漂移特征，不符合物理热力学规律。",

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
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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",

    "关键证据2"
  ],
  "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。

    "推理步骤 3: 结合用户画像（独居老人），这种‘短暂苏醒 - 消失’的模式极可能意味着老人起夜后发生了跌倒、晕厥或其他健康问题导致无法移动，而非正常的睡眠周期。由于缺乏其他房间的联动报警或持续的生命体征反馈，系统未能及时识别这一危险状态。"
