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

  "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",

## 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"
  ],

}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在住户正常外出期间，入户门被非法开启（接触传感器触发），且随后有人员进入玄关并活动。",
  "reasoning": [
    "推理步骤 1: 分析 2026-08-04 和 2026-08-05 的时间线。在 08:25 (8/04) 和 08:29 (8/05)，front_door_contact 状态变为 False，表明有人打开了入户门。",
    "推理步骤 2: 结合上下文判断开门性质。此时卧室 occupancy 为 1 (有人)，但 living_room_occupancy 在开门瞬间及之后短时间内为 0 (例如 8/04 08:25 时客厅无人，8/05 08:30 时客厅无人)。如果是住户正常出门，通常会有离开卧室或前往玄关的动作导致客厅/卧室 occupancy 变化，或者开门后紧接着看到客厅有人活动。",
    "推理步骤 3: 关键异常点在于开门后的活动模式。在 8/04 08:25 开门后，entrance_occupancy 在 08:40 才变为 1，中间存在约 15 分钟的空白期；而在 8/05 08:29 开门后，entrance_occupancy 在 08:39 变为 1。更可疑的是，在 8/05 08:00 左右，living_room_occupancy 曾短暂归零，随后 08:29 开门，08:44 客厅再次有人。这种‘屋内有人 -> 门被打开 -> 屋内无人/状态不明 -> 外人进入’的模式，高度符合尾随 (tailgating) 或强行闯入后潜入的特征，尤其是对于独居老人家庭，非预期的门开启是最高风险事件。",
    "推理步骤 4: 排除误报。虽然可能是住户开门，但日志中缺乏明确的‘住户出门’序列（如先离开卧室再开灯出门），且两次事件发生在极短的时间窗口内（间隔不到 24 小时），增加了重复作案或持续威胁的可能性。"
  ],
  "key_evidence": [

    "2026-08-05T08:29:02 front_door_contact StateValue=False (门再次被打开)",
    "开门前后 living_room_occupancy 与 entrance_occupancy 的状态转换逻辑不符合常规住户出行习惯（如开门后无立即的室内人员移动记录）"
  ],
  "recommended_actions": [
    "立即联系独居老人确认其安全状况及是否遭遇入侵。",
    "检查入户门锁的物理状态，确认是否存在机械故障或被破坏的痕迹。",
    "建议升级门锁系统，启用防尾随功能或更换为带有远程监控和即时报警的智能锁。",
    "通知当地警方备案，特别是考虑到连续两天发生类似事件。"

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

    "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_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器出现严重数据漂移和丢失，导致无法准确监测烹饪安全及火灾风险。",
  "reasoning": [
    "推理步骤 1: 在 18:53 用户开启灶具后，厨房温度传感器读数从正常的约 23-24°C (x10) 开始异常波动，并在短时间内急剧上升至 2575、2694、2716 等数值。考虑到室内环境温度通常在 20-25°C 之间，这些读数（即 25.75°C - 27.16°C）虽然看似合理，但结合后续趋势看存在逻辑矛盾：通常灶具开启会导致局部高温，但传感器随后并未持续上升或报警，反而在 18:54 突然变为 None。",
    "推理步骤 2: 更关键的异常在于数据的非物理性跳跃和缺失。例如在 18:10 读数为 2525 (25.25°C)，18:15 跳至 2575，18:20 跳至 2648，这种阶梯式快速上升不符合热传导规律。最致命的是 18:54 在灶具开启且温度显示极高的情况下，传感器值突变为 `None`，表明设备可能死机、通信中断或电池耗尽，导致关键的安全监控盲区。",
    "推理步骤 3: 对比其他房间，卧室和客厅的温度传感器读数稳定且符合室温特征（~22-23°C），排除了全屋网络故障或环境突变的可能性。因此，问题锁定在厨房温度传感器本身的硬件故障或固件错误，这直接导致了在有人烹饪时无法有效触发烟雾报警器联动或向用户发送高温预警，构成了潜在的火险隐患。"

    "同期卧室和客厅温度传感器数据正常，排除了系统性网络故障。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的电池电量及物理连接状态。",
    "重置厨房温度传感器并重新校准，观察是否恢复正常。",
    "在修复前，建议用户在烹饪时保持人工留意，或暂时手动关闭自动联动功能以防误报/漏报。",

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。

    "作息规律性分析：日志显示住户在每日 06:20-07:00 左右起床（卧室 occupancy 变为 1），随后前往厨房（kitchen occupancy 变为 1）和客厅活动，晚上 23:49 后离开客厅，次日清晨再次进入，这种跨天重复的模式符合独居老人稳定的生活节奏，无异常徘徊或长时间滞留现象。",
    "温度数据合理性校验：所有温度传感器读数（如 living_room_temp_sensor 的 2504 代表 25.04°C）均在舒适且安全的范围内（约 24-26°C），且随时间推移有合理的波动，未出现高温预警或传感器漂移导致的数值突变。",
    "关键安全事件确认：入户门锁在 08:39 执行了手动上锁操作（LockOperationType=1），表明住户具备正常的安防意识；同时未检测到烟雾、漏水或门窗非法开启等报警信号，运动传感器仅在有人活动时触发，逻辑自洽。"
  ],
  "key_evidence": [
    "每日固定时间段内卧室、厨房、客厅的运动传感器触发序列与老人起床、做饭、活动的习惯完全吻合。",
    "入户门锁记录到明确的手动上锁事件，证明物理安防措施已正确执行。",

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：

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",
  "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，无安全威胁或异常行为。",
  "reasoning": [
    "时间线分析：事件发生在 2026-07-10 的傍晚至夜间（07:13 - 20:03），符合典型的下班回家、晚餐及休息时段。",
    "人员流动逻辑合理：入户门在 18:13 和 18:20 两次被打开并随后关闭，伴随玄关和客厅 occupancy 变为 1，表明住户正常进出。门锁状态在开门后保持解锁（LockState=2），符合有人在家场景。",
    "设备状态一致：温度传感器读数（约 23°C）处于舒适范围且波动正常；多个房间（客厅、儿童房、餐厅等）同时检测到 occupancy=1，表明家庭成员分布合理，不存在单人出现在多处的矛盾或入侵迹象。",
    "关键设备行为正常：前门接触传感器在关门后正确报告 False（未受干扰），空调和灯光按预期开启，未发现传感器卡死、数据漂移或恶意控制迹象。"
  ],
  "key_evidence": [
    "front_door_contact 在 18:13 和 18:20 随人员进出正常切换状态，且后续长时间保持关闭 (False)。",
    "living_room_occupancy 和 kids_room_occupancy 在晚间持续为 1，与 dining_room_light 开启等生活场景吻合。",
    "temperature_sensor 读数稳定在 2300K (23°C) 左右，无异常高温或低温报警。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议定期查看完整日志以确认长期模式的一致性。"
  ]
}
