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 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",

  ],
  "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。

    "1. 时间异常：日志显示在连续三天（7月1日、2日、3日）的凌晨 03:14 左右，客厅运动传感器（living_room_occupancy）均从 0 变为 1，表明有人在深夜/凌晨进入客厅。这通常不属于正常的睡眠或休息时间段。",
    "2. 关联行为异常：在 7月3日 03:15，紧随客厅人员出现后，厨房灯（kitchen_light）被开启（OnOff = True）。虽然前两天的同一时间点未记录到厨房灯动作（可能因日志筛选或设备未触发），但“深夜起床+开灯”的组合增加了可疑性。特别是7月3日的联动更为明显。",
    "3. 排除误报：所有卧室和玄关的运动传感器在凌晨 03:00-04:00 期间均保持为 0（无人），说明该活动并非家庭成员起夜经过走廊，而是直接出现在客厅区域。结合温度传感器数据平稳，无火灾或极端天气迹象，排除了环境因素导致的传感器误触。",
    "4. 模式一致性：这种每天凌晨固定时间出现的活动具有高度规律性，若住户无特殊夜班习惯，极有可能是非法入侵者或智能家居系统受到恶意控制/干扰。"

## 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：

```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: 07:28 记录到一次手动解锁和开门操作，紧接着在 16:29 和 18:19 分别记录了两次手动上锁操作。这些时间点（早晨出门、下午回家/短暂外出、傍晚回家）与典型的家庭作息高度吻合，且均为手动操作，排除了远程恶意控制或自动故障的可能性。",
    "推理步骤 3: 整个日志片段中，所有房间的运动传感器状态逻辑自洽（无人时灯亮可能是预设场景或误触但无持续占用信号，有人时未出现矛盾），且关键安防设备（门锁、传感器）工作正常，未检测到尾随、非法闯入或设备故障等异常模式。"

    "04:09 开门后仅 1 分钟即打开客厅灯，符合起床开灯习惯。",
    "07:28 的开门操作发生在早晨，且后续有正常的日间上锁记录。",

    "无需采取紧急措施，系统运行正常。",

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
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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: 综合评估跨天摘要与设备状态：全天各房间 occupancy 计数分布均匀，无长时间无人但门窗开着的异常情况，也无传感器数据冲突（如门开着但锁是锁上的）。对于独居老人而言，这种规律的夜间短暂外出和白天的正常往返属于健康的行为模式，而非异常。"

## 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
{

  "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 2: 环境数据关联。在此期间，客厅温度传感器读数从约 23°C (2299mK) 持续上升至超过 24°C (2411mK)。虽然空调可能开启，但结合无人状态，这种升温可能是由于缺乏人员调节（如忘记关窗、忘记开空调或空调故障），或者是为了掩盖某种情况（如火灾初期烟雾导致传感器误报或真实升温）。",
    "推理步骤 3: 关键事件触发。在 T02:31:00 和 T02:32:00，客厅和卧室的窗户接触传感器状态变为 False (打开)。此时屋内无人，窗户被打开可能导致热量流失或进入，但也可能是有人试图通风后离开，或者更危险的是，有人在夜间开窗透气后未返回，增加了老人独自暴露在极端天气或发生意外的风险。随后直到早上 09:48 才检测到有人活动，中间间隔过长。",
    "推理步骤 4: 综合判断。独居老人 + 整夜无活动 + 窗户异常开启 + 温度变化，高度疑似老人夜间突发疾病昏迷、跌倒无法移动，或是发生了其他意外导致无法进行正常活动。这不仅仅是简单的'不在家'，而是需要紧急干预的'健康关注'信号。"

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

  "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。
