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
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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
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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到凌晨2:07阳台门被打开，随后玄关灯亮起且客厅有人活动，存在非法入侵或异常进入的高风险。",
  "reasoning": [
    "1. 时间异常：事件发生在凌晨02:07至02:30之间，属于典型的深夜/凌晨时段，此时住户通常处于睡眠状态，非正常活动时间。",
    "2. 物理入口开启：日志显示 `balcony_door_contact` 在 02:07 变为 False（即门被打开）。虽然阳台门可能用于通风，但在深夜结合后续行为需警惕。",
    "3. 连锁反应与人员移动：阳台门打开后仅1分钟（02:08），`balcony_light` 被点亮。紧接着在 02:09，`living_room_occupancy` 变为 1（有人）。这表明有人从阳台区域移动到了客厅。",
    "4. 排除误报：虽然日志中未直接显示入户门（entrance）的传感器触发，但“阳台开门 -> 开灯 -> 客厅有人”这一序列符合入侵者通过阳台进入并在家中活动的模式。即使是通过阳台进入，也构成了未经授权的进入行为（Intrusion）。",
    "5. 持续活动：客厅 occupancy 在 02:30 才变回 0，说明有人在客厅停留了约20分钟，进一步证实了这是人为活动而非传感器故障。"

## 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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "多个窗户传感器短时依次触发",
  "reasoning": [
    "推理步骤1: 短时间内两个不同房间窗户先后打开",
    "推理步骤2: 触发时间位于深夜",
    "推理步骤3: 随后出现室内运动"
  ],
  "key_evidence": [

  "threat_description": "凌晨时段（02:31-04:10）在无人居住且窗户被打开的情况下，客厅温度持续异常升高并突破安全阈值，存在严重火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间与环境状态分析。日志显示在 02:31 至 02:32 期间，客厅和卧室的窗户传感器（window_contact）状态变为 False（打开），随后在 02:34 检测到有人进入客厅（occupancy=1）。然而，该人员仅短暂出现后，在 03:00、03:30、04:00 等多次连续时间点报告 occupancy=0，表明该时段内房屋实际上处于无人看管或人员已离开的状态。",
    "推理步骤 2: 温度异常趋势分析。从 02:35 开始，客厅温度传感器读数从正常的 23°C 左右（2346 mK ≈ 23.46°C）开始急剧上升。到 04:00 时，读数达到 2401 mK (24.01°C)，并在 04:05 达到峰值 2411 mK (24.11°C)。对于独居老人家庭，夜间室温通常应保持稳定或缓慢下降，这种在短时间内快速升温且伴随开窗的行为极不寻常。",
    "推理步骤 3: 威胁关联与排除。虽然窗户打开可能导致热量交换，但如此剧烈的温升（约 1 小时内上升近 1 度以上，且趋势未因开窗而平衡）更符合热源（如电器故障、线路过热或初期火灾）的特征。考虑到住户为独居老人，夜间发生电气火灾的风险较高，且烟雾报警器未在日志中触发报警事件（可能尚未达到阈值或传感器未上报），这构成了潜在的火灾隐患。"

  "key_evidence": [

    "02:35 至 04:10 期间客厅温度持续单调递增，从 ~23.46°C 升至 ~24.11°C，呈现典型的火源加热特征而非自然散热",
    "独居老人夜间活动模式与高温时段重合，缺乏人工干预降温的迹象"
  ],
  "recommended_actions": [
    "立即远程通知住户或其紧急联系人，告知可能存在火灾隐患。",
    "建议系统自动联动关闭客厅空调（如果开启）并尝试通过语音助手询问住户情况（若设备支持）。",
    "检查客厅及厨房区域的烟雾报警器电池及灵敏度，确保其正常工作。",
    "安排次日上门检修，重点排查客厅电路老化、电器过载或燃气泄漏问题。"

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。

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",
  "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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "连续多天同一时段出现陌生运动模式",
  "reasoning": [
    "推理步骤1: 连续 3 天都在 03:14 出现客厅运动",
    "推理步骤2: 时间点高度一致",
    "推理步骤3: 第 3 天继续延伸到厨房活动"
  ],
  "key_evidence": [

    "时间点高度一致",
    "第 3 天继续延伸到厨房活动"
  ],
  "recommended_actions": [

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的夜间活动模式稳定，无入侵、火灾或设备故障迹象，环境安全。",
  "reasoning": [
    "推理步骤 1: 分析 occupancy_sensor 数据，发现每晚（约 02:30-04:30）均出现一致的'空房'状态，随后在凌晨 03:14 左右短暂检测到人员活动（Occupancy=1），并在次日清晨（23:53/23:45）再次检测到活动，这符合独居老人起夜如厕或查看情况的正常生物节律，且跨三天模式高度一致。",
    "推理步骤 2: 检查 temperature_sensor 数据，虽然数值以毫开尔文（mK）为单位（例如 2399 mK ≈ 24°C），但温度随时间呈现合理的物理变化趋势（夜间降温至最低点，随后缓慢回升），且客厅与厨房温差合理，未出现传感器漂移或卡死导致的异常恒定值或剧烈跳变。",
    "推理步骤 3: 核查关键安全设备日志，未发现烟雾报警器触发、漏水传感器报警、门锁异常开启或灶具在非预期时间开启的记录；kitchen_light 仅在白天特定时间（11:01/11:02）开启，符合日常作息，不存在 unattended_cooking 风险。"
  ],
  "key_evidence": [
    "连续三天在相同时间段（凌晨 03:14）检测到短暂的居住者活动信号，随后迅速恢复空房状态，符合正常睡眠周期中的起夜行为。",
    "所有温度传感器读数随时间呈平滑的物理变化曲线，无突变或逻辑错误，且未伴随任何烟雾或漏水警报事件。",
    "入户门和窗户传感器在整个监测期间均未报告非法闯入或意外开启事件。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查老人卧室及卫生间区域的照明亮度，确保夜间起夜时路径清晰，防止跌倒风险。"
