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",

    "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。

    "无异常入侵迹象：虽然厨房窗户传感器在 19:10 报告打开（False），但此时厨房灯已开，灶具随后开启，且后续没有检测到其他房间（如客厅、主卧）出现非预期的频繁进出或长时间无人值守的开窗行为，结合整体高频率的人员活动记录，极可能是住户正常开窗通风。",
    "关键安全设备工作正常：烟雾报警器、漏水传感器等未在日志中触发报警事件；门锁操作为手动且逻辑连贯；所有运动传感器和接触传感器的状态变化均与人员移动轨迹吻合，无传感器卡死或漂移现象。"
  ],
  "key_evidence": [
    "入户门锁于 18:09 执行手动上锁操作，随后室内各区域活动正常展开。",
    "温度数据随空调启动（18:19 OnOff=True）呈现持续、平滑的下降趋势，表明温控系统响应正常。",
    "厨房窗户在 19:10 打开时，伴随有灯光开启和随后的烹饪活动，符合居家生活场景。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期检查厨房窗户密封性，以防极端天气下的安全隐患。"

## 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": [
    "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。

  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：住户在卧室锁门并开启主灯后，前门被从外部打开（接触传感器状态翻转），随后门锁被手动解锁，且客厅无人但温度异常升高。",
  "reasoning": [
    "时间线分析：2026-07-13T07:23:17 主卧灯光关闭，紧接着在 07:23:38 入户门接触传感器 (front_door_contact) 状态变为 False（表示门被打开）。",
    "逻辑矛盾：此时主卧运动传感器显示有人 (Occupancy=1)，且用户刚刚关灯准备休息或离开卧室，正常情况下不应有人去开门。更可疑的是，如果这是住户自己开门，通常会有相应的出门动作记录，但随后立即发生了门锁操作。",
    "关键证据链：07:23:38 门被打开 -> 07:23:39 门锁执行了 'LockOperationType=0' (通常为 Unlock/开锁) 且来源为 'Manual'。这种‘先开门再手动开锁’的顺序极不自然，暗示可能有人尾随进入后试图重新上锁失败，或者是在门外通过某种方式触发了开门信号并尝试控制门锁。",
    "环境异常佐证：日志中大量出现温度传感器读数（如 living_room_temp_sensor 在 07:55 达到 2556 mK 即 22.8°C，后续持续高位），结合 occupancy 传感器在白天大部分时间显示为 0（无人），可能存在非正常居住模式或设备被干扰导致误报，但最直接的威胁是门口的物理安全突破。",
    "排除误报：虽然温度数据存在漂移（Matter 协议中常以毫开尔文 mK 为单位，2500mK=21.85°C，数值本身合理），但门口传感器的状态变化与门锁操作的紧密时序关联构成了明确的入侵特征。"

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",

    "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。

  "reasoning": [
    "时间线分析：日志显示从早晨到傍晚（07:16-18:50），入户门传感器和门锁状态变化规律，伴随玄关灯开启和客厅空调/灯光自动启动，符合住户下班回家的正常生活模式。",

    " occupancy 逻辑一致：各房间运动传感器报告与人员进出记录（entrance_occupancy）高度吻合，例如 18:18 进入后客厅和主卧随后检测到有人，18:30 离开后检测为空，无幽灵占用或长时间无人却开门的异常情况。"
  ],
  "key_evidence": [
    "18:18:00 入户门锁手动上锁 (LockOperationType=1) 且随后门传感器变为 False (打开)，紧接着玄关灯亮起，符合回家流程。",
    "18:18:24 客厅空调开启并设定模式为 Cooling (SystemMode=3)，随后室内温度读数呈现持续下降趋势，表明温控系统工作正常。",
    "全时段内无烟雾报警器、漏水传感器或窗户非法开启等安全类设备的异常报警事件。"
  ],
  "recommended_actions": [

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

    "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。

  "reasoning": [
    "入住与离开时间高度一致：每天早晨约 07:10-07:20 玄关传感器检测到进入，随后厨房和客厅温度上升（表明开始烹饪/开启空调），晚上约 15:25 后客厅再次有人但无后续夜间活动记录，符合独居老人白天外出或居家休息的常规作息。",
    "多房间 occupancy 状态逻辑自洽：当卧室 occupancy 为 1 时，卧室温度传感器持续报告数据；当客厅 occupancy 变为 1 时，客厅温度随之变化且灯光开启，不存在‘人在某处但传感器未响应’或‘无人却频繁触发’的矛盾现象。",
    "关键安全设备工作正常：入户门锁在 08:26 被锁定（LockState=2），窗户接触传感器、烟雾报警器等未出现异常跳变或长时间离线，漏水传感器也未触发警报，排除了 sensor_malfunction 或 safety_device_failure 的可能性。"
  ],
  "key_evidence": [
    "每日固定时段（~07:15）entrance_occupancy 从 0 变为 1，紧接着 kitchen_temp_sensor 数值上升，表明正常的起床和早餐准备流程。",
    "living_room_light 在 08:26:13 被打开，此时 living_room_occupancy 也为 1，动作与状态同步，无延迟或冲突。",
    "连续三天 bedroom_occupancy 和 living_room_occupancy 的变化曲线平滑，无突然的长时间空置后瞬间多人进入等可疑模式。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期（如每周）人工核对一次门锁电池电量及烟雾报警器功能，作为预防性维护。"

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",

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。

## 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",
  "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": "behavioral_anomaly",
  "threat_description": "连续多天不使用厨房",
  "reasoning": [
    "推理步骤1: 多天都有居家活动",
    "推理步骤2: 却始终没有厨房使用线索",
    "推理步骤3: 可能反映生活能力或情绪异常"
  ],
  "key_evidence": [
    "多天都有居家活动",
    "却始终没有厨房使用线索",
    "可能反映生活能力或情绪异常"
  ],
  "recommended_actions": [
    "判定为连续行为缺失异常，建议结合住户状态评估。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示住户活动规律正常，设备运行符合预期，未发现安全威胁或异常模式。",
  "reasoning": [
    "温度数据验证：所有温度传感器（living_room, kitchen, bedroom）报告的数值均在 2406-2558 范围内。考虑到 Matter 协议中温度通常以 0.01°C 为单位存储，这些数值对应 24.06°C - 25.58°C，属于夏季室内正常的室温波动范围，排除了传感器故障或漂移（sensor_drift/sensor_malfunction）。",
    " occupancy 行为分析：卧室和客厅的占用状态变化与时间戳高度吻合。例如，早晨 06:30-07:00 期间卧室有人且随后离开，紧接着 07:16 门锁被手动解锁并开门，随后厨房开始有温度读数（暗示烹饪或电器使用），这构成了完整的‘起床 - 出门/准备早餐’逻辑链条，符合正常生活作息。",
    " 设备联动逻辑：日志中未出现违反物理常识的冲突事件。例如，当检测到窗户打开（contact_sensor=False）时，并未伴随烟雾报警或异常高温；门锁操作（LockOperation）前后接触传感器状态变化合理。夜间及清晨无长时间无人但高能耗或异常活动的迹象。"
  ],
  "key_evidence": [
    "温度读数稳定在 24-26°C 区间，无极端高温或低温异常。",
    " 07:16 门锁解锁事件与随后的厨房温度上升、卧室人员离开事件在时间线上形成合理的因果序列。",
    " 跨天活动摘要显示各房间占用次数分布均匀，无异常的长时间静止或频繁闯入迹象。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期校准温度传感器以确保长期精度，尽管目前读数正常。"
  ]
