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
{
  "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: ..."

    "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。

    "环境数据一致性：全屋温度传感器读数波动范围小（约 23.7°C - 24.5°C），无火灾风险的高温报警或烟雾报警器触发记录。",
    "结论：所有设备状态变化均能由合理的住户行为解释，未发现入侵、尾随、设备故障或安全隐患。"
  ],
  "key_evidence": [
    "kids_room_occupancy 在白天多次报告为 1，且温度正常，排除空房隐患。",
    "front_door_lock 操作源为 Manual，且后续伴随正常的室内人员流动。",

## 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: ...",
    "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。

Chosen response:

  "is_anomaly": true,

  ]
}

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示为正常的家庭晚间降温过程及次卫灯光误报/定时开启，无安全威胁。",
  "reasoning": [
    "推理步骤 1: 温度数据分析。所有房间的温度传感器读数（如 kids_room_temp_sensor）均在 23°C - 24°C 之间波动，且数值随时间推移呈现缓慢下降趋势（从约 24.4°C 降至 23.3°C），这符合傍晚关闭空调或自然散热的正常物理规律。Matter 协议中温度通常以 0.1°C 为单位，因此读取值需除以 10，当前数值完全在舒适居住范围内，不存在过热或设备故障导致的漂移。",
    "推理步骤 2: 占用状态分析。虽然儿童房 (kids_room) 和客厅等区域在 15:00 至 17:40 期间持续报告无人 (Occupancy = 0)，但这与跨天摘要中显示的各房间活动量一致，且考虑到这是下午晚些时候，住户可能已离开该区域或处于休息状态，属于正常的生活作息模式，未检测到入侵迹象（因为门窗传感器未触发异常报警逻辑，且全屋无其他闯入特征）。",
    "推理步骤 3: 异常事件关联分析。日志中出现的 `second_bathroom_light` 在 16:30、16:45、17:00 多次变为 True，而该房间此时无人且非活动时间。然而，结合上下文，这可能是智能照明系统的定时任务、场景联动（如离家模式下的安防灯测试）或用户远程控制的误操作记录。由于没有伴随漏水、烟雾或其他危险信号，且温度正常，此行为被判定为非恶意或无害的自动化行为，不构成安全威胁。"
  ],
  "key_evidence": [
    "儿童房温度从 24.44°C 稳定下降至 23.39°C，符合环境散热规律，无异常高温。",
    "全屋运动传感器长时间为 0 但未触发入侵警报，且无门窗接触传感器异常开启记录。",
    "次卫灯光频繁开启但无相关危险事件（如漏水、烟雾）伴随，推测为自动化控制而非人为入侵。"
  ],
  "recommended_actions": [
    "无需紧急干预，系统运行正常。",
    "建议检查智能家居 App 中的次卫灯光设置，确认是否为预期的定时任务或场景联动，若非预期可调整配置。"

System:
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。

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
{
  "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。

Chosen response:

  "threat_description": "未检测到安全威胁或异常模式，所有设备状态变化符合正常家庭活动规律。",
  "reasoning": [
    "1. 儿童房活动分析：日志显示儿童房 occupancy 传感器在 08:20 至 16:36 期间持续报告占用状态（Occupancy=1），中间虽有短暂的时间间隔，但整体呈现为白天的正常居家活动。温度传感器数据在 24.1°C - 24.5°C 之间波动，属于舒适且稳定的室内温度范围，无剧烈变化暗示设备故障或环境异常。",
    "2. 厨房与卫生间灯光逻辑：厨房灯在 06:35 开启并于 07:19 关闭，符合早晨起床后的常规使用习惯。次卫灯在 16:30 开启，结合此时段其他房间（如主卧、主卫）的占用情况，推测为家庭成员正常的洗漱或清洁活动，无长时间无人亮灯的异常情况。",
    "3. 入户门与安防状态：16:22 记录到入户门锁手动上锁（LockState=2）及门磁关闭（StateValue=False），随后玄关运动传感器在 16:27 再次触发。这一序列表明有人在家中进行日常出入或检查门窗，且门锁状态正常，未出现非法入侵迹象（如强行开锁或门未关严）。",
    "4. 多房间协同活动：下午时段（15:40-16:30），客厅、主卧、主卫、餐厅等多个区域相继出现占用信号，随后部分区域（如客厅、次卧）在 16:00/16:30 变为空闲。这种分散且随时间推移的人员流动模式符合典型的多人口家庭在白天的生活节奏，不存在单一人员长时间静止不动（可能跌倒）或完全无活动的反常情况。"
  ],
  "key_evidence": [
    "kids_room_occupancy 在 08:20-16:36 期间持续为 1，配合稳定的温度读数，确认为正常居家活动。",
    "kitchen_light 06:35 On -> 07:19 Off，符合早晨作息。",
    "front_door_lock LockState=2 (Locked) 且 front_door_contact StateValue=False (Closed)，安防状态正常。",
    "多个房间 occupancy 传感器的交替触发反映了正常的家庭内部人员移动。"
  ],
  "recommended_actions": [
    "无需采取任何紧急措施。",

Rejected response:

System:
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",

    "关键证据1",
    "关键证据2"
  ],
  "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。

  "reasoning": [
    "1.  occupancy传感器分析：儿童房（kids_room）的运动传感器在大部分时间显示为0（无人），仅在16:36短暂变为1后迅速恢复为0。这种短暂的触发通常对应于宠物活动、灰尘干扰或人员快速经过，且没有伴随其他房间（如客厅、主卧）的持续占用信号，不符合入侵者长时间潜伏的特征。",
    "2.  温度数据分析：所有房间的温度传感器读数在23°C-24°C之间波动，数值呈现自然的缓慢下降趋势（从约24.4°C降至23.4°C左右）。这符合夏季傍晚自然降温或空调运行的正常物理规律，没有出现急剧升温（火灾风险）或异常低温。",
    "3.  设备状态分析：厨房灯（kitchen_light）在16:40开启，次卫灯（second_bathroom_light）在16:30开启。这些是常见的日常行为。虽然厨房灯开启时厨房运动传感器未明确记录（可能因采样间隔或传感器盲区），但结合温度正常且无烟雾报警器触发，排除未看管烹饪引发火灾的风险。",
    "4.  综合判断：整个时间段内没有门锁异常操作、漏水报警、烟雾报警或持续的非法占用迹象。所有事件均在智能家居系统的正常预期范围内。"

    "推理步骤 2: 然而，对比同一时间段内 living_room、master_bedroom、kitchen 等其他房间的温度传感器数据，其数值均在 2338 到 2422 之间（即 23.3°C - 24.2°C）。虽然数值区间有重叠，但 kids_room 的读数普遍偏高且呈现无规律的剧烈跳变（如 14:50 的 2436 vs 15:15 的 2422），而实际物理环境在同一建筑内不应出现如此显著的温差差异。",
    "推理步骤 3: 结合 occupancy_sensor 显示该房间长期无人（Occupancy=0），排除了人体热源导致局部升温的可能性。这种单一传感器持续输出偏离物理常识的高位数值（可能是单位错误导致的 2400 而非 24.00，或是硬件漂移），被归类为 sensor_malfunction（传感器故障/漂移），可能导致错误的空调控制或火灾误报风险。"

System:
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。
