## 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: ...",

    "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": [
    "凌晨 02:11 门锁解锁并开门",
    "玄关灯随后开启",
    "紧接着出现室内活动，不像误触"
  ],
  "recommended_actions": [
    "标记为异常入户，建议检查临时访客码使用记录并立即重置。"
  ]
}

{
  "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。"
  ],

## 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

  "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。

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",

    "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。

  "reasoning": [
    "时间序列分析：所有异常事件均发生在凌晨 01:40 至 04:50 之间，且呈现高度规律性（每晚约 03:14 出现一次短暂的 Occupancy=1），这符合独居老人夜间起夜、使用卫生间后返回卧室的常规行为模式，而非入侵者特征。",
    "温度数据合理性：虽然温度传感器数值较大（如 2318-2440），但结合上下文推断单位应为毫开尔文 (mK) 或特定协议下的编码值，换算后约为 23°C - 24°C，属于夏季夜间正常的室内空调调节范围；且厨房与客厅温度同步上升，排除了单一传感器漂移或局部热源（如有人长时间在厨房烹饪）的可能性。",
    "设备状态一致性：入户门、窗户等接触传感器在夜间全程保持未触发状态（无开门/开窗事件），烟雾报警器无报警记录，漏水传感器无异常，门锁状态稳定，排除了入侵、火灾和漏水风险。",
    "跨天对比：三天（7 月 28 日 -30 日）的活动摘要和设备事件模式高度一致，表明这是住户的稳定习惯，不存在突发的行为异常或健康危机（如跌倒导致的长时间静止）。"
  ],
  "key_evidence": [

    "厨房灯光仅在白天（10:50, 10:50）开启，夜间无烹饪相关活动（灶具未触发，温度无异常飙升）。",
    "所有房间的门窗接触传感器在夜间连续数小时保持关闭状态，无非法闯入迹象。"
  ],
  "recommended_actions": [
    "确认当前系统运行正常，无需立即干预。",
    "建议定期复核温度传感器的原始单位配置，确保用户界面显示的温度直观准确（避免 mK 直接显示导致误解）。",
    "鉴于住户为独居老人，可考虑在夜间起夜时段（03:00-04:00）自动增强走廊或卫生间照明亮度，以辅助其行动安全。"

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 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

  "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: 对比卧室温度传感器数据（约 2240-2300），其数值变化趋势平缓且符合夜间降温后的回升规律（考虑到空调运行），而客厅温度在住户出现前（03:14 Occupancy=1）和出现后持续攀升至 2400+ 的异常高位，这种跨房间的巨大温差（>100 单位）不符合热力学常识。",
    "推理步骤 3: 结合独居老人场景，虽然不能直接断定是入侵者带来的热源，但传感器数据的剧烈漂移（Drift）会导致温控系统失效、能耗激增，甚至掩盖真实的火灾隐患（如真实火灾时传感器可能因故障无法上报正确数据），属于高优先级的设备可靠性问题。"

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：

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: 环境数据关联分析。在此期间，客厅温度传感器读数从约 22.9°C (2294mK) 持续上升至超过 24.0°C (2407mK)。虽然夏季夜间气温较高，但结合长达 10 小时的无人状态，这种温升趋势表明空调系统可能未开启或失效，或者房间密闭导致热量积聚。若老人因突发疾病卧床不起，高温环境将迅速加剧脱水或中暑风险。",
    "推理步骤 3: 排除误报与入侵。虽然窗户传感器在 T02:31 和 T02:32 变为 False（打开），但这发生在运动传感器已报告无人之后，且随后并未检测到新的进入事件（直到早上）。这更像是老人醒来后开窗通风，或者是之前遗留的状态变化，而非外部入侵者进入的迹象（因为入侵者通常会触发运动传感器或被摄像头/其他传感器捕捉到活动轨迹）。核心问题在于‘人’的消失而非‘外人’的进入。"

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。
