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。

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",

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。

请按以下 JSON 格式回答：

```json

## 任务
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

请按以下 JSON 格式回答：

  "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。

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": [

    "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": "credential_theft",
  "threat_description": "临时访客码在非预约时段使用",
  "reasoning": [
    "推理步骤1: 凌晨 02:11 门锁解锁并开门",
    "推理步骤2: 玄关灯随后开启",
    "推理步骤3: 紧接着出现室内活动，不像误触"
  ],
  "key_evidence": [

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的夜间无人值守状态及白天的常规出入活动，未发现安全威胁。",
  "reasoning": [
    "推理步骤 1: 分析夜间时段 (00:00 - 07:15)，所有房间运动传感器均报告 Occupancy=0，且门锁保持锁定状态 (LockState=2)，符合住户外出或睡眠时的正常无人模式。",
    "推理步骤 2: 检查 02:11 的异常事件序列：门锁解锁 (LockState=2) 和门接触传感器变 False 后，紧接着在 02:12 玄关灯自动开启，随后在 02:13 客厅检测到人员进入 (Occupancy=1)。这种'开门即亮灯、随即有人进入'的强时序关联表明这是住户回家并触发自动化场景的正常行为，而非入侵者试探。",
    "推理步骤 3: 验证白天时段 (07:15 - 21:47)，门锁操作记录显示标准的'手动解锁 -> 开门 -> 关门 -> 重新上锁'流程，且伴随正常的室内人员活动检测，最后以住户离家（门锁上锁、门关闭）结束，整体行为模式符合预期。"
  ],
  "key_evidence": [
    "02:11 门锁解锁后立即触发玄关灯开启，且 1 分钟后客厅检测到人员存在，证明是住户回家。",
    "整个监控周期内，所有房间在无人时均无非法闯入迹象，门锁操作逻辑完整且符合人工控制特征。"
  ],
  "recommended_actions": [
    "确认当前系统运行正常，无需采取紧急措施。",
    "建议继续监控后续日志，关注温度传感器读数是否出现非预期的剧烈波动。"

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",

    "推理步骤 1: 分析 occupancy_sensor 数据，发现住户在每日凌晨 03:14 左右有短暂的客厅活动记录（Occupancy=1），但仅持续约 2-3 分钟后即恢复为 0，且后续直到次日深夜 23:47/23:51 才再次检测到活动。这种‘短暂出现 - 消失 - 长时间静默’的模式符合独居老人夜间起夜如厕或饮水后的典型行为，但也可能是跌倒后无法移动导致的静止状态。",
    "推理步骤 2: 结合温度传感器数据分析，在老人最后一次被检测到活动（03:14）之后，客厅温度从正常的 23°C 左右开始持续攀升，至凌晨 04:50 达到 24.4°C（日志值 2441）。对于独居老人而言，若发生跌倒受伤，通常不会主动调节空调或进行其他产生热量的活动，导致室温随时间自然上升或空调误开升温，这与正常睡眠期间的恒温模式不符。",
    "推理步骤 3: 对比三天日志，该模式高度一致（均在 03:14 左右活动，随后室温持续爬升），表明这是一种重复发生的潜在风险场景。考虑到住户为独居老人，一旦在此时间段发生意外（如跌倒、中风），由于长时间无活动信号且环境变化未被及时干预，极易造成严重后果。"

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

## 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",

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。

    "4. 室内活动确认：02:09 `living_room_occupancy` 变为 1，表明有人进入了客厅主要活动区域。结合之前的阳台门开启和灯光操作，这构成了一个完整的‘进入-照明-活动’链条。",
    "5. 排除误报：虽然可能是住户起夜，但直接开启阳台灯并进入客厅的行为在深夜较为罕见，且没有看到卧室人员起床的对应记录（如主卧门开或主卧灯亮），增加了外人入侵或内部异常行为的可能性。"

## 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",

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": [
    "数据单位分析：日志中的温度值（如 2317, 2439）明显超出了摄氏度（°C）的合理物理范围（通常 -20 到 60）。结合 Matter 协议常见实现，这些数值极有可能是以 0.01°C 为单位的原始整数表示，即实际温度为 23.17°C 至 24.39°C。",
    "趋势异常识别：尽管换算后温度看似正常，但观察原始日志发现，从 01:40 (23.17) 到 04:50 (24.39)，客厅温度在短短 3 小时内呈现持续、线性的快速上升趋势（每小时上升约 0.4°C），而卧室和厨房在同一时间段内温度保持相对稳定或变化平缓。这种跨房间的不一致升温模式不符合自然热力学规律（除非有外部热源持续加热客厅，但日志中无空调开启记录）。",
    "设备行为矛盾：在 03:14 检测到有人进入客厅（Occupancy=1）后，温度读数并未出现人员活动常见的波动或稳定，而是继续单调递增。随后在 03:30 人员离开（Occupancy=0），温度依然继续上升直至凌晨 04:50 达到峰值。真实的 occupancy 事件通常不会导致环境温度在无其他干预下持续单向升高，这强烈暗示是传感器校准失效或硬件故障导致的读数漂移。"
