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",

  ],
  "recommended_actions": [

    "跨天活动模式稳定性：对比三天摘要，虽然 07-06 和 07-07 的 entrance 事件数显著高于 07-05（可能包含周末访客或外出归来多次），但各房间内部的 occupancy 变化与温度波动均呈现自然的昼夜节律（早晨升温、夜间无人），未出现设备长时间离线、误报或逻辑冲突（如门开着但人不在却持续报警）。",
    "关键设备状态正常：厨房灶具、烟雾报警器、漏水检测器等安全相关设备在日志中无异常触发记录；洗衣机、洗碗机等家电仅在预期时间段有少量交互或无交互，符合待机或正常使用状态。"

## 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": [
    "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": "回家后跳过常规过渡行为直接进卧室",
  "reasoning": [
    "推理步骤1: 入户后缺少常见过渡动作",
    "推理步骤2: 直接切到卧室活动",
    "推理步骤3: 偏离既往居家路径"
  ],
  "key_evidence": [
    "入户后缺少常见过渡动作",
    "直接切到卧室活动",
    "偏离既往居家路径"
  ],
  "recommended_actions": [
    "判定为行为模式异常，建议结合其他迹象评估状态。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭晚间活动模式，包括住户回家、开启灯光空调、准备晚餐及锁门，未发现安全威胁。",
  "reasoning": [
    "时间线分析：日志始于凌晨至清晨（00:00-08:25），随后在 16:40 开始密集上报温度数据，这符合傍晚时分环境传感器的高频采样或校准特征，而非异常入侵迹象。",
    "行为逻辑验证：17:30 左右玄关和客厅出现人员活动（Occupancy=1），紧接着在 18:11 发生入户门锁手动上锁操作，随后前门接触传感器状态变为 False（开门/未关严？需结合上下文，但紧接着 18:20 又显示 False，可能是开门取物或传感器抖动，但整体流程连贯）。更关键的是，18:11 之后住户开启了客厅灯、空调，并在 18:24 开启厨房灶具，这是典型的‘回家 - 开灯 - 做饭’的生活场景。",
    "设备状态一致性：所有温度读数（约 23°C）处于正常舒适范围，无过热或骤降；烟雾报警器未触发；漏水传感器无报警。虽然 18:25 厨房温度传感器短暂报空值 (None) 后恢复，但这属于常见的通信丢包或重启现象，且不影响后续读数，不构成故障。",
    "结论：整个序列展示了完整的‘归家 - 生活 - 烹饪’闭环，没有检测到尾随进入、非法闯入、火灾风险或设备卡死等异常模式。"
  ],
  "key_evidence": [
    "18:11 入户门锁执行手动上锁操作 (LockOperationType=1)，表明住户主动控制门禁。",
    "18:11 至 18:24 期间，客厅灯、空调、厨房灯及灶具依次开启，符合正常居家生活习惯。",
    "全时段室内温度维持在 23°C 左右，无极端异常波动，且烟雾/漏水传感器无报警事件。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议定期维护厨房温度传感器，防止因信号干扰导致的数据丢失（如 18:25 的 None 值）。"
  ]
}

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",
  "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": "behavioral_anomaly",
  "threat_description": "连续多天不使用厨房",
  "reasoning": [

}

```json

  "threat_type": "none",
  "threat_description": "日志显示住户活动规律，设备状态与时间戳逻辑一致，未发现安全威胁或异常模式。",
  "reasoning": [
    "入住/离家模式正常：日志清晰展示了典型的每日生活节奏（早晨起床、白天在客厅活动、晚上回卧室休息），且跨天数据摘要中各房间事件计数稳定，符合正常居住习惯。",
    "温度读数逻辑正确：所有温度传感器报告的值均在 2400-2560 范围内，对应实际温度约 24.0°C - 25.6°C，处于舒适且安全的家庭环境范围，无高温过热或低温异常迹象。",
    "门锁操作合规：入户门仅在早上 07:21 出现一次完整的‘解锁 - 开门 - 关门’序列，随后门接触传感器状态变为 False（门外），符合正常的出门行为，无非法入侵或锁具故障迹象。",
    " occupancy 状态连贯：运动传感器的状态变化（0 到 1）均发生在合理的活动时间段内，且没有检测到长时间无人但温度持续升高的异常情况（排除火灾风险）。"
  ],
  "key_evidence": [
    "2026-08-27T07:21:00 至 07:21:28 期间记录了标准的出门开锁和关门流程。",
    "全天温度读数稳定在 24°C-26°C 之间，未出现超出正常范围的波动。",
    "跨天活动摘要显示 living_room 和 bedroom 的事件数量在三天内保持相对稳定的日常水平。"
  ],
  "recommended_actions": [
    "继续保持当前的设备监控策略。",
    "定期校准温度传感器以确保长期准确性。"
  ]

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

    "数据合理性检查：温度传感器读数约为 23xx (即 23.x°C)，数值稳定且符合室内正常环境温度范围，排除了传感器漂移、故障或火灾风险；设备状态切换流畅，无卡死现象。",
    "综合判断：所有设备交互均遵循预期的因果关系，未发现异常模式、未授权访问尝试或环境安全隐患。"
  ],
  "key_evidence": [
    "18:20 front_door_contact 变为 False (关门) 后紧接着 18:21 living_room_light_1 开启和 18:22 master_bedroom_occupancy 变为 1，行为逻辑连贯。",
    "全时段各房间 occupancy 状态与时间戳匹配，无长时间无人却灯光常亮或门窗异常开启的情况。",
    "温度传感器数据稳定在 23°C 左右，无剧烈波动或超出合理范围的数值。"

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",

    "推理步骤 1: 分析日志发现，从 2026-07-12T16:40:00 开始，living_room_temp_sensor 报告的 MeasuredValue 在 2376 到 2350 之间。智能家居设备通常使用摄氏度 (°C) 或华氏度 (°F)，但即使是华氏度，2376°F 也意味着超过 1300°C 的极端高温，这在普通住宅环境中是不可能的；如果是摄氏度，则更是严重错误。",
    "推理步骤 2: 观察后续数据变化，数值并未稳定在一个合理的室温（如 20-25°C/68-77°F），而是呈现出不规则的下降趋势（2376 -> 2350 -> 2342...），并在 18:45 左右降至 2292。这种‘高位虚高后缓慢回落’的模式不符合真实环境温度随空调或自然散热变化的线性规律，更像是传感器读数溢出、校准错误或通信噪声导致的异常值。",
    "推理步骤 3: 结合上下文，同一时间段内其他房间（主卧、儿童房、厨房）的温度传感器读数均在 2300-2340 左右的区间波动（同样存在单位或基准偏移嫌疑，或者整体系统存在某种偏移），但客厅作为重点监控区域，其初始读数显著高于其他区域且逻辑上不合理。考虑到入户门在 18:20 打开，若为入侵者携带热源，温度应迅速上升并伴随运动传感器触发，但运动传感器全程显示无人（Occupancy=0），排除了人为热源导致的高温可能性。因此，最可能的原因是传感器硬件故障、固件 bug 或 Matter 协议传输中的数据类型解析错误。"

## 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": [
    "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": "回家后跳过常规过渡行为直接进卧室",
  "reasoning": [
    "推理步骤1: 入户后缺少常见过渡动作",
    "推理步骤2: 直接切到卧室活动",
    "推理步骤3: 偏离既往居家路径"
  ],
  "key_evidence": [
    "入户后缺少常见过渡动作",
    "直接切到卧室活动",
    "偏离既往居家路径"
  ],
  "recommended_actions": [
    "判定为行为模式异常，建议结合其他迹象评估状态。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭晚间活动模式，包括住户回家、开启灯光空调及多房间人员分布，未发现安全威胁。",
  "reasoning": [
    "时间线分析：日志始于清晨（07:33）入户门打开，随后在傍晚（16:30）再次打开，符合典型的‘离家 - 回家’日常作息。",
    "行为逻辑验证：18:17 入户门锁被手动上锁，紧接着（18:17:06）客厅运动传感器检测到有人进入，随后（18:17:15）用户主动开启客厅灯和空调，这一系列操作完全符合住户回家的正常行为逻辑。",
    "环境状态确认：虽然 16:40-18:25 期间温度传感器数值异常高（如 2378），但这极可能是 Matter 协议中单位换算错误（实际应为 23.78°C）或传感器校准漂移导致的读数偏差，而非真实的火灾风险；同时，所有房间（主卧、儿童房、厨房等）均检测到人员存在，且无烟雾报警触发，进一步排除了真实火情或入侵的可能性。"
  ],
  "key_evidence": [
    "18:17:00 前门手动上锁 (LockOperationType=1) 后，系统立即检测到室内有人活动并开启照明/空调，证明是合法住户返回。",
    "多个房间（master_bedroom, kids_room, kitchen, dining_room）在同一时间段内持续报告 Occupancy=1，表明家庭成员分散在各处正常活动，非单人潜入或异常聚集。"
  ],
  "recommended_actions": [
    "建议检查客厅温度传感器的固件版本或校准设置，以解决读数单位异常问题（例如将 2378 修正为 23.78）。",
    "无需采取紧急安全措施，当前环境处于受控的安全状态。"
  ]
