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",

    "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。

  "threat_description": "儿童房温度传感器读数异常偏高（约 22.4°C-22.6°C，显示为 2243-2266），且数值波动剧烈，不符合正常室温特征，疑似传感器漂移或故障。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 21:40 至 23:25 期间频繁上报温度值，但数值均在 2243 到 2266 之间。根据 Matter 协议及常见传感器规范，TemperatureMeasurement.MeasuredValue 通常以 0.1°C 为单位，因此实际温度约为 22.43°C 至 22.66°C。虽然这个范围本身看似合理，但需结合上下文判断。",
    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据（如 living_room 22.58°C, master_bedroom 22.60°C, kitchen 22.48°C）。所有房间温度高度一致且处于舒适区间（约 22.5°C），这表明环境温度整体是稳定的，并非全屋过热。",
    "推理步骤 3: 关键疑点在于 kids_room 的读数变化模式。在 22:30 时读数为 2243 (22.43°C)，随后在 22:35 跳变为 2257 (22.57°C)，并在后续几分钟内在 2243-2266 之间无规律剧烈跳动。真实的物理环境在短时间内不会发生如此频繁的微小幅度和大幅度的随机波动，这种‘锯齿状’的高频噪声是典型的传感器漂移（Drift）或校准失效特征，而非真实的热源变化。",
    "推理步骤 4: 尽管 occupancy_sensor 显示有人存在，但温度传感器的异常行为与正常的热力学规律不符。如果是因为有人活动导致体温升高，温度应缓慢上升并稳定在一个略高的水平，而不是像电子噪声一样随机跳动。因此，判定为 sensor_drift。"

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
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",

    "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。

    "推理步骤 3: 连续三次的 Keypad 错误通常意味着密码被遗忘、键盘卡键、电池电量低导致信号传输不稳定，或者是有人正在尝试暴力破解/猜测密码（虽然频率较低，但需警惕）。考虑到这是智能家居安全分析，必须优先排除设备本身的硬件故障（malfunction）或潜在的入侵尝试。",
    "推理步骤 4: 尽管温度传感器读数（如 2380 mK = 23.8°C）看似合理，但门锁的连续错误是更直接的安全威胁指标，需要立即干预以防止住户被困或外部人员利用此机会进入。"

## 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",

    "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。

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": [

    "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": "儿童反复尝试打开受限区域",
  "reasoning": [

Rejected response:

  "threat_description": "入户门锁在住户离家时段连续三次出现键盘操作错误，且随后长时间无人员进出活动，存在门锁故障或潜在入侵风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线与 occupancy 状态。日志显示从 17:30 开始，包括 entrance、living_room、kids_room 等所有主要区域的运动传感器均报告 Occupancy = 0，表明住户已完全离开家中。",
    "推理步骤 2: 识别关键异常事件。在 18:05 至 18:07 期间（即确认无人后约 35-40 分钟），front_door_lock 连续三次上报 LockOperationError(source=Keypad)。这表明有人在尝试使用键盘开锁但失败，或者系统自身出现了严重的交互故障。",
    "推理步骤 3: 排除误报并评估风险。虽然可能是内部人员测试导致误报，但在‘全屋无人’的状态下发生多次连续的锁具操作错误，极大概率意味着：(1) 有外部人员在门外尝试非法进入；(2) 门锁固件/硬件严重故障导致无法正确响应合法指令。无论哪种情况，都构成了安全威胁。",
    "推理步骤 4: 结合环境数据。此时室内温度正常下降趋势符合夜间模式，无火灾或漏水迹象，进一步排除了其他类型的紧急事件，将焦点锁定在门锁安全上。"

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
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。

Rejected response:

  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在连续三次按键尝试后均报告操作错误，且此时门传感器显示门处于开启状态，存在门锁故障或遭暴力破坏的风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-07-08T17:48:00 时，用户手动锁门（LockOperationType=1），随后门接触传感器（front_door_contact）立即变为 False（False 通常代表门未闭合/开启），这表明门可能并未完全锁好，或者传感器检测到门缝。",
    "推理步骤 2: 紧接着在 18:05:00 至 18:07:00 之间，门锁连续三次收到来自 Keypad（键盘/密码盘）的 LockOperationError 事件。这种短时间内连续的失败尝试是典型的异常行为模式，可能是内部机械卡死、电池耗尽导致电机无法响应，或者是外部有人正在尝试破解密码但未能成功。",
    "推理步骤 3: 结合上下文，家庭其他区域（如客厅、主卧）仍有人员活动（Occupancy=1），说明并非全家外出后的无人看管场景。门锁在有人在家且刚进行过手动上锁操作的情况下出现连续报错，极大概率是设备本身的硬件故障（actuator_stuck 或 lock_malfunction），这直接威胁到家庭物理安全边界。"
