## 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",

    "00:10 至 05:28 期间，客厅及厨房温度持续攀升至 24°C 以上，表明室内缺乏人员流动带来的热交换，且空调未有效运行（日志中未见空调控制指令），加剧了高温风险。",
    "05:28 再次开启卧室灯，距离上次开灯已超过 3 小时，说明老人醒来或有人进入，但中间长达数小时的静默期构成了高危窗口。"

## 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。

Chosen response:
{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],

Rejected response:

  "threat_description": "独居老人在凌晨时段出现长时间无活动且室内温度异常升高，存在健康风险或意外滞留的可能性。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析。日志显示在 2026-08-01T00:00:00 至 05:20:06 之间，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的运动传感器持续报告 Occupancy = 0，长达超过 5 小时无任何人员活动迹象。对于独居老人而言，整夜完全无活动属于极度异常的‘静默’模式。",
    "推理步骤 2: 环境状态关联。在此期间，客厅和厨房的温度传感器读数持续上升并达到极高水平（例如 living_room_temp_sensor 从 22.7°C 升至 23.9°C+，kitchen_temp_sensor 甚至达到 23.7°C+）。考虑到空调设备未出现在活跃控制列表中，且温度呈单向上升趋势，这暗示可能缺乏有效降温措施，或者有人体热源但未被运动传感器检测到（如老人静止不动、跌倒或昏迷）。",
    "推理步骤 3: 关键事件缺失。直到 T05:20:06 卧室灯才被打开，此时距离上次任何活动记录已过去 5 个多小时。这种‘长时无人 + 高温累积 + 延迟唤醒’的组合模式，强烈指向老人可能在夜间发生了跌倒、突发疾病导致无法移动，或是因睡眠障碍/意识模糊而长时间未进行正常活动，而非正常的深度睡眠（通常会有翻身等微小动作触发传感器或温度波动）。"

    "卧室灯光在 T05:20:06 才首次被开启，表明该时段内住户处于完全无响应状态。"

    "立即通过家庭自动化系统拨打紧急联系人电话或发送警报通知家属/监护人。",
    "若配备远程视频门铃或室内摄像头，尝试查看实时画面确认老人状态。",

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。

    "2. 关键时间窗行为验证：在早晨07:30-09:30的关键起床和准备时段，厨房(kitchen)和客厅(living_room)的运动传感器均检测到持续的人体存在(Occupancy=1)，且温度传感器读数随人体活动和可能的烹饪/洗漱略有上升，符合正常生活逻辑。",
    "3. 门锁与安防状态：入户门(entrance)仅在早晨短暂开启后关闭，且随后玄关灯亮起，符合老人出门买菜或散步后返回的正常流程。全天无深夜非法入侵迹象，也无多次无效开锁尝试。",
    "4. 环境安全指标：所有烟雾报警器、漏水传感器在提供的日志片段中未触发报警事件，温度读数处于舒适范围（24-25°C左右），未发现火灾、燃气泄漏或水患风险。"

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: ...",

    "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。

Chosen response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示住户活动规律，门锁状态与传感器数据一致，符合独居老人的正常生活模式。",
  "reasoning": [
    "1. 门锁状态分析：重点关注的 front_door_contact 在三天内多次报告为 False（关闭/锁定）。在 2026-07-24T08:30:00 记录到 door_lock.LockState = 2 (Locked)，且此时 entrance_occupancy 为 1（有人），随后 living_room_occupancy 变为 0 又变为 1，表明住户可能在门口停留后进入室内并锁门，这是正常的离家或归家行为，未发现非法入侵迹象。",
    "2. 传感器一致性检查：门窗传感器（contact_sensor）与运动传感器（occupancy_sensor）的状态逻辑自洽。例如，当门窗关闭时，室内仍有人员活动（occupancy=1），说明是住户在屋内活动而非外人闯入；若门窗打开，通常伴随短暂的入口区域活动，未见长时间门窗开启且无人员活动的异常滞留情况。",
    "3. 活动模式稳定性：对比三天的跨天活动摘要，各房间的活动计数（如 living_room=209, bedroom=241等）保持高度稳定，温度读数也在合理范围内波动（25°C左右），没有突发的环境变化或长时间的人员静止（可能跌倒）迹象。"
  ],
  "key_evidence": [
    "front_door_contact 持续为 False，配合 door_lock.LockState = 2，确认门锁处于安全锁定状态。",
    "entrance_occupancy 在门锁操作前后有短暂激活，符合住户进出逻辑。",
    "连续三天各房间活动计数稳定，无剧烈波动，排除突发异常事件。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议定期校准门窗传感器以确保长期准确性。"
  ]
}
```

Rejected response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "正常样本仍保持日常出门；异常样本后续数天只剩室内活动。"

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
{
  "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。

Chosen response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示独居老人的日常活动模式稳定且符合预期。",
  "reasoning": [
    "1. 活动模式一致性分析：对比2026-08-16至08-18的跨天摘要数据，各房间的活动计数（如living_room约209-210次，bedroom约240-242次）保持高度稳定，表明住户的生活作息规律，无突发的长时间静止（可能暗示跌倒或昏迷）或异常的高频活动。",
    "2. 关键区域行为逻辑验证：日志显示厨房（kitchen）和客厅（living_room）在早晨7:30-10:00期间有持续的运动传感器触发（Occupancy=1），这符合老人起床、准备早餐及晨间活动的正常行为轨迹。没有发现无人时的烹饪设备开启或长时间滞留厨房等“unattended_cooking”迹象。",
    "3. 环境与安全状态检查：温度传感器读数在合理范围内波动（客厅约25°C，卧室约24°C），无极端高温提示火灾风险。入户门传感器仅在早晨短暂记录到状态变化（可能是开门/关门动作），随后恢复常态，无非法入侵特征。所有烟雾报警器和漏水传感器在提供的片段中未触发告警。"
  ],
  "key_evidence": [
    "连续三天（16-18日）各房间运动传感器触发次数统计高度一致（Living Room ~209, Bedroom ~241），证明生活规律稳定。",
    "早晨时段（07:30-10:00）Kitchen和Living Room Occupancy持续为1，符合正常的晨间活动流程，无异常中断。",
    "TemperatureMeasurement数值稳定在舒适区间（2400-2550对应24-25.5摄氏度），无火灾或设备故障导致的温度飙升。"

  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "客厅温度传感器报告的数据严重异常（数值在 2500-2560 之间），远超正常室温范围，表明传感器故障或校准错误。",
  "reasoning": [
    "1. 数据合理性分析：日志中 living_room_temp_sensor 报告的 MeasuredValue 持续在 2500 至 2560 之间波动。根据 Matter 协议标准及物理常识，环境温度通常在 -40°C 到 +85°C 之间，即 40000 到 85000 的毫开尔文 (mK) 单位，或者如果是摄氏度则应在 0-35 左右。当前数值若解读为摄氏度则不可能；若解读为 mK，则对应约 2.5°C 至 2.6°C，这与夏季（8 月）室内空调开启或自然升温的环境（日志显示卧室温度约 24°C/24000mK）完全不符。",
    "2. 跨设备对比验证：同一时间段内，bedroom_temp_sensor 和 kitchen_temp_sensor 报告的数值约为 2400-2500 (对应 24-25°C)，符合人体舒适区及夏季室内常态。唯独客厅传感器读数出现数量级偏差或单位混淆，导致其显示的“温度”比实际低约 20 多度（如果按 mK 算）或者是一个毫无意义的巨大数字（如果误读为 C）。",
    "3. 行为模式关联：尽管传感器读数异常，但 occupancy_sensor 显示老人有正常的活动轨迹（起床、去厨房、回卧室等），且其他房间温度正常，说明并非全屋断电或极端天气导致，而是单一设备故障。对于独居老人家庭，错误的温度反馈可能导致空调系统无法正确调节（例如因误报低温而不开启制冷，或因逻辑混乱频繁启停），存在健康隐患。"

    "该异常数值与 8 月份的季节特征及室内其他区域温度严重背离，不符合物理规律。"
