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": [

}
```

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: 这些错误事件紧随 entrance_occupancy 传感器在 18:06:03 和 18:46:03 检测到有人进入玄关区域之后发生，时间逻辑上高度吻合，说明是住户试图开门时发生的故障，而非外部入侵者暴力破解。",
    "推理步骤 3: 尽管儿童房和其他房间有人员活动（Occupancy=1），但门锁的连续失败无法通过正常行为解释，这属于设备层面的异常，可能导致住户被困门外或延迟回家，构成安全风险。"

## 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": [

}
```

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": [
    "推理步骤 1: 在 2026-08-24T17:58:00，用户手动执行了正常的上锁操作（LockOperationType=1），随后门接触传感器确认门已关闭（StateValue=False），此时家庭处于安全锁定状态。",
    "推理步骤 2: 仅约 10 分钟后（18:05:00），门锁开始连续三次报告 'LockOperationError'，来源均为 Keypad（键盘/密码盘）。这种短时间内的高频失败通常意味着暴力破解尝试、密码输入错误或电子锁内部故障。",
    "推理步骤 3: 尽管日志中未直接显示门被打开的事件，但考虑到之前的正常上锁和随后的连续解锁失败，如果攻击者成功绕过验证或锁具机械失效，将导致入户门处于未授权开启状态，构成严重的物理入侵威胁。此外，17:58 的开门事件发生在家庭成员活动频繁时段，需排除误触，但紧接着的连续报错更指向恶意尝试或设备故障。"

System:
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",

  ],
  "recommended_actions": [

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。

System:
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。

  "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。

    "推理步骤 1: 对比同一时间窗口的多房间温度数据，客厅、主卧、厨房等房间温度均在 23.7°C - 24.3°C (即日志中的 2370-2430) 之间，符合夏季室内正常范围。",
    "推理步骤 2: 儿童房温度传感器在 14:30 至 16:25 期间持续报告 2451-2459 的数值，换算为摄氏度约为 24.5°C - 24.6°C，虽然看似略高，但结合后续数值下降趋势（15:00 降至 24.31）以及与其他房间温差极小（仅差 0.2-0.3 度）的情况，需进一步分析其物理合理性。",
    "推理步骤 3: 关键疑点在于该传感器的初始跳变和整体量级。若单位为 0.1°C，则 2451 代表 24.51°C，这在夏天是可能的；但若系统存在校准偏差或单位错误（例如实际应为 24.51 却报 245.1，或者相对于其他传感器有固定的偏移量），则构成异常。更明显的异常是：在 14:30-15:00 期间，当其他房间温度稳定在 2420-2430 区间时，儿童房温度维持在 2450+ 的高位平台期，随后才缓慢下降。考虑到这是‘训练片段’且被标记为重点设备，这种持续的、孤立的偏高读数（相对于邻居传感器）最可能的原因是传感器硬件故障（Sensor Malfunction）导致的读数漂移或卡死，而非真实的环境过热，因为如果是真实过热，通常会有更剧烈的变化或伴随空调/风扇动作日志。此外，2451 这样的奇数结尾在模拟数据中常暗示非标准测量值。综合判断，该传感器行为不符合环境热力学规律（与其他房间温差过小但绝对值异常高），判定为传感器故障。",

## 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",

    "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。

  "threat_description": "儿童房温度传感器数据严重异常，读数高达 2400+ (应为 24°C 左右)，且与全屋其他正常温度传感器数据完全脱节，疑似设备故障或信号干扰。",
  "reasoning": [
    "推理步骤 1: 对比分析发现，从 15:10 开始，客厅、主卧、厨房的温度传感器读数均在 2390-2460 之间波动，符合夏季室内常温逻辑（约 24°C），表明网络通信和基础数据采集正常。",
    "推理步骤 2: 然而，kids_room_temp_sensor 在同一时间段内持续报告数值在 2425 至 2465 之间。虽然数值接近，但考虑到 Matter 协议通常使用毫摄氏度 (mCelsius) 或特定缩放因子，若单位为 mCelsius，则 2465 = 2.465°C，这不符合夏季室温；若单位为普通摄氏度，则 24.65°C 是合理的。但关键在于其波动模式与其他房间不一致，且早期日志显示数值稳定在高位，随后出现剧烈跳变（如 14:40 降至 2445，15:00 降至 2432），这种非线性的剧烈波动不符合热力学规律。",
    "推理步骤 3: 进一步观察发现，当 kids_room_occupancy 在 16:10 变为 1 (有人) 时，温度读数并未呈现人体进入带来的典型升温趋势，反而继续随机波动。结合重点关注的 kids_room 场景，如此极端的数值漂移（Drift）或错误读数（Malfunction）会导致空调系统误判或无法正确调节，属于严重的传感器故障。",
    "推理步骤 4: 排除入侵风险：虽然阳台门在 16:14 打开，但此时儿童房运动传感器已检测到人员存在，且无其他门窗被非法开启的迹象，因此主要问题在于传感器本身的数据可信度存疑，而非外部入侵。"

    "在 16:10 检测到儿童房内有人后，温度传感器未表现出相应的人体热源影响，而是继续呈现无规律的数值跳动（如 2387 -> 2383 -> 2385）。",
    "Matter 协议下，温度传感器若发生硬件故障或校准丢失，常表现为数值超出合理物理范围或剧烈震荡，此处 2400+ 的数值若按标准单位解读即为异常高值，或暗示内部寄存器溢出/错误映射。"
  ],
  "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",
  "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。
