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": [
    "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。

    "推理步骤 1: 分析 occupancy_sensor 数据发现，住户在每天凌晨 03:14 左右有规律的短暂进入客厅活动（Occupancy=1），持续约 16 分钟后离开（Occupancy=0）。这种‘短暂出现 - 迅速消失’的模式符合独居老人夜间起夜如厕的典型行为，但缺乏后续的日常活动迹象。",
    "推理步骤 2: 对比温度传感器数据，发现从凌晨 02:00 开始，客厅温度呈现持续上升趋势（从 23.1°C 升至 24.4°C+），且在老人离开客厅后（03:30 及之后），温度并未回落至正常睡眠环境温度，反而继续攀升。这表明热源可能来自人体代谢（若老人未离开房间）或空调/暖气故障，结合老人长时间未再出现在客厅，更倾向于老人被困在某个区域（如卧室或卫生间）导致局部过热或环境恶化。",
    "推理步骤 3: 综合来看，老人每日凌晨固定时间短暂活动后，直到深夜 23:55 才再次被检测到在客厅（可能是第二天早上起床或误报），中间长达数小时无任何活动记录。对于独居老人而言，这种‘夜间活动后长期失联’的模式是典型的潜在跌倒、晕厥或突发疾病后的静止状态，属于高风险的健康关注事件。"

    "在老人离开客厅后，客厅温度持续异常升高（最高达 24.4°C），未恢复至正常水平，暗示可能存在人员滞留或设备故障。",
    "两次监测周期内，老人离开凌晨活动点后，直到次日深夜 23:55 才再次出现活动信号，中间存在超过 20 小时的‘静默期’。"
  ],
  "recommended_actions": [
    "立即通过家庭自动化系统拨打紧急联系人电话或发送警报通知家属/监护人。",

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",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

  ],

    "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2: 阳台灯随即被点亮",
    "推理步骤3: 随后出现客厅活动"
  ],

  ]
}

```json
{

  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "室内温度传感器读数严重偏离物理现实（显示为 2300K+），且与人体活动逻辑矛盾，表明传感器存在故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 日志中所有房间的温度传感器（living_room, master_bedroom, kids_room, kitchen）在凌晨时段报告的数值均在 2299 到 2367 之间。考虑到 Matter 协议通常使用摄氏度 (°C)，这些数值意味着室温高达 2300°C，这在家庭环境中是不可能的；若单位为开尔文 (K)，则对应约 -2°C 至 -4°C，但在夏季（7 月）且无空调开启记录的情况下，全屋同时降至冰点也不符合常理。",
    "推理步骤 2: 观察时间线发现，当阳台门被打开（02:07）并有人进入客厅（02:09）时，温度读数并未发生任何合理的物理变化（如开门导致的气流交换或人员体温影响），而是继续维持着异常的固定高位数值，直到凌晨 03:30 后数据突然消失。",
    "推理步骤 3: 结合 occupancy_sensor 的数据，虽然检测到有人进入和离开，但温度传感器完全没有响应环境变化，这种‘死值’或‘漂移’现象排除了正常的人为操作或环境波动，确认为传感器硬件故障或通信数据错误。"
  ],
  "key_evidence": [
    "2026-07-27T01:20:00 至 02:55:00 期间，多个房间温度传感器持续报告 2299-2367 的异常数值。",
    "在 02:07 阳台门打开及 02:09 检测到人员进入客厅时，温度读数未出现任何符合物理规律的波动。",
    "该异常模式持续近 2.5 小时，随后数据中断，符合传感器故障特征而非临时干扰。"
  ],
  "recommended_actions": [
    "立即检查并更换所有受影响的温度传感器设备。",
    "审查 Matter 网络配置，确认是否存在固件版本不兼容导致的单位解析错误（例如将 mK 误读为 °C）。",
    "在修复前，暂时忽略基于这些温度数据的自动化场景（如恒温控制、高温报警），以防误触发。"

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: ...",

    "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": "多个窗户传感器短时依次触发",
  "reasoning": [
    "推理步骤1: 短时间内两个不同房间窗户先后打开",
    "推理步骤2: 触发时间位于深夜",
    "推理步骤3: 随后出现室内运动"
  ],
  "key_evidence": [
    "短时间内两个不同房间窗户先后打开",
    "触发时间位于深夜",
    "随后出现室内运动"
  ],
  "recommended_actions": [
    "判定为扫描式入侵尝试，建议重点检查窗户和周边摄像头。"
  ]
}

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "这些变化仍可视为正常波动。",
  "reasoning": [
    "推理步骤1: 没有看到必须报警的直接证据。"
  ],
  "key_evidence": [
    "设备状态变化幅度看起来仍在可接受范围内。"
  ],
  "recommended_actions": [
    "保持观察即可。"
  ]
}


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 3 天的设备活动记录。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",

    "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 2: 在同一无人时间段内，living_room_temp_sensor 的 MeasuredValue 从约 23.0°C (2309) 持续上升至 24.4°C (2440)。虽然夏季室温可能升高，但在完全无人的封闭空间内，温度通常应趋于稳定或缓慢下降（因墙体散热），而非出现这种明显的、持续的线性升温趋势。",
    "推理步骤 3: 对比其他房间数据，master_bedroom 和 second_bedroom 的温度变化相对平缓，且没有同步出现如此剧烈的单向升温。这种孤立的、不符合物理规律的快速升温模式，强烈指向传感器本身出现了漂移（Drift）或校准错误，而非真实的环境热源导致。"
