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。

  "confidence": "medium",
  "threat_type": "child_safety",

  "reasoning": [

  ],

```json
{

  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：住户在离开家并锁门后，阳台门被非法打开，且随后儿童房灯光被开启。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 16:05:00 入户门锁被手动上锁 (LockState=2) 且前门传感器状态变为 False (开门)，表明住户已正常离家。",
    "推理步骤 2: 仅 9 秒后 (16:05:09)，阳台门传感器 (balcony_door_contact) 状态变为 False (False 通常表示接触断开/门开)，而日志中未记录任何人员进入阳台的 occupancy 事件或阳台灯自动开启，这暗示有人通过非正常方式（如撬锁、窗户等）打开了阳台门。",
    "推理步骤 3: 更关键的异常发生在 16:11:00，此时屋内无人 (living_room_occupancy=0, kids_room_occupancy=1 但结合上下文可能是误报或短暂停留，且主人在外)，儿童房灯光 (kids_room_light) 突然被手动开启。考虑到儿童房是重点保护区域，且此时家中主要成员已外出，该操作极不寻常，符合入侵者试图确认室内情况或寻找目标的特征。"
  ],
  "key_evidence": [
    "16:05:00 入户门锁锁定且前门关闭，确认住户已离家。",
    "16:05:09 阳台门传感器状态突变 (False)，无伴随的人员进入记录。",
    "16:11:00 儿童房灯光在无明确触发源的情况下被开启，且此时客厅及主卧均无人。"
  ],
  "recommended_actions": [
    "立即通知住户返回家中，检查门窗安全状况。",
    "联系当地警方报告潜在的入室盗窃或非法侵入事件。",
    "检查阳台门锁具是否损坏或被破坏，并考虑更换为更高安全等级的锁芯。",
    "审查家庭安防系统日志，确认是否有其他设备（如摄像头）记录了入侵者的影像。"

## 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: ..."

    "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": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 儿童房活动后很快打开阳台门",
    "推理步骤2: 阳台灯被打开",
    "推理步骤3: 缺少明确陪同信号"
  ],
  "key_evidence": [
    "儿童房活动后很快打开阳台门",
    "阳台灯被打开",
    "缺少明确陪同信号"
  ],
  "recommended_actions": [
    "判定为儿童接近高处风险区域，建议立即干预。"
  ]
}

{
  "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。

## 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

  "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。

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",

## 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。

    "推理步骤 2: 紧随这些错误之后（18:02:02），front_door_contact 传感器状态变为 False（False 通常代表门已打开或未闭合），结合之前的手动上锁操作（17:40:00 LockState=2），说明门被打开但并未成功重新锁定，或者是在错误尝试后被迫/被他人打开。",
    "推理步骤 3: 考虑到这是针对重点房间 kids_room 的分析任务，且发生在傍晚时段（18:00+），连续的认证失败紧接着门状态异常，极有可能是外部攻击者尝试暴力破解密码，或者是内部人员试图绕过正常流程进入/离开，构成了明确的门禁系统失效和潜在入侵威胁。"

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：

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

  "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 21:40 开始，kids_room_temp_sensor 报告的温度值均为 22xx (如 2241, 2258)，换算后约为 22.4°C - 22.6°C。虽然夏季室温可能较高，但需结合上下文判断。",

    "推理步骤 3: 考虑到该设备位于儿童房，且住户习惯中儿童房通常有空调或恒温控制（虽日志未直接显示空调开启，但 22.5°C 对于有人的卧室略高，若无人则应更低）。更重要的是，传感器数值的‘噪声’特征（Sensor Drift/Malfunction）表现为数据点的不连续跳跃，而非平滑的物理升温/降温过程。这种异常模式可能导致错误的自动化触发（如误判过热关闭空调）或掩盖真实的安全隐患。",

## 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": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 儿童房活动后很快打开阳台门",
    "推理步骤2: 阳台灯被打开",
    "推理步骤3: 缺少明确陪同信号"
  ],
  "key_evidence": [
    "儿童房活动后很快打开阳台门",
    "阳台灯被打开",
    "缺少明确陪同信号"
  ],
  "recommended_actions": [
    "判定为儿童接近高处风险区域，建议立即干预。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭日间活动模式，无安全威胁或异常行为。",
  "reasoning": [
    "时间线分析：事件发生在 2026-07-09 的下午（08:28 - 16:22），符合典型的白天活动时间窗。",
    " occupancy 逻辑验证：儿童房 (kids_room) 在 08:28 被占用，随后持续有人活动直到 16:13，期间温度传感器读数稳定且与人体热源引起的微幅波动一致（约 24°C），表明有儿童在场且环境正常。",
    " 关键事件序列合理性：16:14 阳台门打开 (False)，紧接着 16:15 阳台灯开启，这是合理的离家/外出准备动作；随后 16:18 入户门锁手动上锁并检测到开门事件，最后 16:20 儿童房灯光开启（可能是家长进入房间整理物品或孩子仍在房内），整个流程逻辑连贯，未发现入侵、尾随或设备故障迹象。",
    " 数据一致性：所有温度传感器读数均在合理范围内（23.8°C - 24.6°C），未出现传感器漂移或卡死现象；运动传感器状态变化与人员移动轨迹吻合。"
  ],
  "key_evidence": [
    "16:14 balcony_door_contact 变为 False (打开) 后立即触发 16:15 balcony_light OnOff=True，符合用户操作习惯。",
    "16:18 front_door_lock 执行 LockOperation(Manual) 且 LockState=2 (锁定)，随后 front_door_contact 变为 False，确认了正常的出门上锁流程。",
    "kids_room_occupancy 在整个时间段内保持为 1，且温度读数稳定，排除了无人看管或异常高温风险。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议定期查看此类跨天活动摘要，以建立更精准的家庭行为基线模型。"
