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
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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": "出门后家中连续多天规律性运动",
  "reasoning": [
    "推理步骤1: 住户出门后仍在固定时间出现室内运动",
    "推理步骤2: 连续三天模式重复",
    "推理步骤3: 缺少对应回家链路"
  ],

    "连续三天模式重复",
    "缺少对应回家链路"
  ],

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "系统日志显示正常的家庭日常活动模式，未发现入侵、设备故障或环境安全隐患。",
  "reasoning": [
    "推理步骤 1: 分析 occupancy_sensor（运动传感器）数据，发现 2026-08-24 中午时段（12:15 - 13:13），entrance, master_bedroom, dining_room, kids_room, living_room 等多个房间同时检测到人员活动，且时间连续，符合家庭成员回家后的正常生活轨迹。",
    "推理步骤 2: 检查 front_door_lock（门锁）事件，仅在 2026-08-24T07:45:27 记录了一次手动上锁操作，随后在白天活动期间未出现异常解锁或未授权访问尝试，符合正常出入习惯。",
    "推理步骤 3: 审查 temperature_sensor（温度传感器）数据，客厅温度在 24°C 至 26°C 之间波动，属于夏季室内正常环境温度范围，无过热或急剧变化迹象；同时未触发烟雾、漏水等安全报警设备的事件。",
    "推理步骤 4: 对比跨天摘要，8 月 24 日各房间活动频次显著高于前两天，这与日志中显示的多人同时在家活动一致，排除了传感器卡死或漂移导致的误报可能。"
  ],
  "key_evidence": [
    "2026-08-24T12:15:30 至 13:13:00 期间，多个房间（entrance, master_bedroom, dining_room, kids_room, living_room）连续报告 Occupancy = 1。",
    "front_door_lock 仅有一次 Manual LockOperation 记录，无异常解锁或强制开启事件。",
    "living_room_temp_sensor 读数稳定在 2459 (24.59°C) 到 2552 (25.52°C) 之间，无危险高温。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持对多房间联动活动的监控，以验证家庭成员的常规作息模式。"
  ]

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
{

  "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",

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",

    "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。

  "threat_description": "室内温度传感器读数异常偏高且数值格式疑似错误（显示为 2200+），导致系统误判环境温度，可能掩盖真实的火灾风险或造成空调/照明设备逻辑混乱。",
  "reasoning": [
    "推理步骤 1: 分析日志发现从 00:35 开始，所有房间的温度传感器（living_room, master_bedroom, second_bedroom, kitchen）报告的温度值均在 2276 至 2341 之间。",
    "推理步骤 2: 结合常识判断，该数值范围远超正常室温（通常为 20-30°C）。若单位为摄氏度则不可能，若单位为毫开尔文 (mK) 则换算后约为 2.2°C - 2.3°C，这不符合夏季（8 月）及有人员活动时的室内环境特征。这表明传感器数据存在严重的漂移、校准错误或固件 Bug。",
    "推理步骤 3: 这种异常的‘高温’读数会导致依赖温度的自动化逻辑失效。例如，厨房烟雾报警器可能在真实火情下因温度阈值判断错误而延迟报警；空调系统可能因认为室内极冷而拒绝启动制冷，或者灯光系统因温度逻辑触发而异常开启。此外，在凌晨时段（01:22）门锁解锁时，全屋温度读数依然处于这一异常高位，进一步证实是系统性数据问题而非局部热源。"
  ],
  "key_evidence": [
    "2026-08-26T00:35:00 至 02:10:00 期间，多个温度传感器连续报告 MeasuredValue > 2200。",

    "同一时间段内，不同房间的温度读数虽然略有波动但整体都偏离正常物理范围，呈现出一致性的数据异常模式。"
  ],
  "recommended_actions": [
    "立即检查并重置所有受影响的温度传感器设备，查看是否有固件更新或校准选项。",
    "暂时禁用依赖这些温度读数的自动化场景（如基于温度的空调控制、烟雾报警联动），改用人工监控或备用传感器。",
    "联系 Matter 协议网关或设备制造商技术支持，排查是否存在批量固件缺陷或通信协议解析错误。"

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。

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

## 任务
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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": "出门后家中连续多天规律性运动",
  "reasoning": [
    "推理步骤1: 住户出门后仍在固定时间出现室内运动",
    "推理步骤2: 连续三天模式重复",
    "推理步骤3: 缺少对应回家链路"
  ],
  "key_evidence": [
    "住户出门后仍在固定时间出现室内运动",
    "连续三天模式重复",
    "缺少对应回家链路"
  ],
  "recommended_actions": [
    "判定为空置期间异常活动，建议按入侵事件处理。"
  ]
}

```json

  "reasoning": [
    "时间线分析：日志记录了从清晨 (06:50) 到下午 (14:26) 的活动。门锁在 07:19 锁定 (LockState=2)，随后在 08:05 解锁 (LockState=1)，符合住户出门上班/外出的正常行为；傍晚 18:06 再次锁定，符合回家后的正常操作。",
    " occupancy 模式验证：客厅运动传感器 (living_room_occupancy) 在 12:00 和 14:00 短暂变为 0，随后在 13:00 恢复为 1，且卧室和卫生间也有相应的进出记录，这表明住户在家内不同房间间移动，而非长时间离家或异常滞留。",
    "环境数据合理性：温度传感器读数在 24.69°C 至 25.50°C 之间波动，属于夏季室内正常室温范围，无过热或骤冷迹象；厨房灶具在 12:26 关闭，与午餐时段吻合，无未attended cooking 风险。",
    "跨天一致性：对比 7-24 至 7-26 的摘要数据，各房间事件计数稳定，未见突增（可能暗示入侵）或突降（可能暗示设备离线），整体行为模式具有高度一致性。"
  ],
  "key_evidence": [
    "DoorLock.LockState 序列 (2 -> 1 -> 2) 符合标准的‘出门 - 回家’循环。",
    "OccupancySensing.Occupancy 在白天呈现间歇性 0 值，但迅速恢复为 1，且伴随其他房间的活动记录，证明是人员移动而非空房。",
    "TemperatureMeasurement 数值稳定在舒适区间，无火灾或极端天气导致的异常波动。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议继续保持对门锁状态和运动传感器的实时监控，以维持现有的安全基线。"
  ]
