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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，所有事件符合正常家庭活动规律。",
  "reasoning": [
    "1. 人员活动轨迹合理：日志显示住户在下午时段（15:40-16:30）主要在主卧、儿童房和餐厅活动，随后有人离开家（入户门锁闭），这符合典型的居家生活节奏。",
    "2. 设备操作逻辑正常：入户门在16:33被手动锁闭（LockState=2, OperationSource=Manual），且门传感器状态变为False（关闭/锁定），这是标准的离家或夜间就寝前的行为。",
    "3. 灯光控制无异常：厨房灯在早晨开启后关闭，傍晚再次开启；儿童房灯在主人离家前开启，可能是为了照明或让孩子准备休息，属于正常的人为控制或自动化场景，未发现长时间无人亮灯等浪费或异常迹象。",
    "4. 环境数据稳定：温度传感器读数在23-24摄氏度之间波动，变化平缓，无剧烈跳变，表明传感器工作正常且室内环境舒适，无火灾或极端天气导致的异常。",
    "5. 无入侵迹象：虽然有人进出（通过运动传感器推断），但结合门锁的手动操作和正常的活动时间段，没有发现非法入侵、尾随或凭证窃取的特征。"
  ],
  "key_evidence": [
    "16:33:00 front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) - 确认是住户主动锁门",
    "16:33:02 front_door_contact | BooleanState.StateValue = False - 门已关闭并锁定",
    "15:41:00 - 16:30:00 多个房间（主卧、儿童房、餐厅）持续有 Occupancy=1 记录，显示住户在家活动",
    "Temperature readings remain stable between 2371 and 2451 (approx 23.7-24.5°C), indicating normal environmental conditions"
  ],
  "recommended_actions": [
    "无需采取任何紧急措施。",
    "建议继续保持当前的智能家居自动化规则，如离家自动布防。"
  ]
}
```

{
  "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": [
    "正常样本浴室活动后很快回到正常房间链路；异常样本长时间停留单一敏感区域。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]

## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",

  "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。",

    "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。"
  ],

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

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。",

    "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。"

## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，日志显示为正常的家庭日常活动及环境数据上报。",
  "reasoning": [
    "1. **人员活动符合常理**：06:34 次卫亮灯、07:10 厨房亮灯随后熄灭，符合早晨起床洗漱和准备早餐/咖啡的习惯。15:20-16:30 期间儿童房 occupancy 持续为 1，且温度传感器频繁上报（每5分钟一次），表明孩子在房间内活动，家长可能在附近监控或孩子正在玩耍/学习，属于正常行为。",
    "2. **门锁状态正常**：16:33 入户门执行了 Manual Lock 操作并关闭，这是典型的离家或归家后的上锁动作，无非法入侵迹象（如暴力开锁或异常时间段的反复尝试）。",
    "3. **设备状态无故障**：虽然儿童房温度传感器在 14:50-16:30 期间上报频率较高（约5分钟一次），但这通常是因为房间有人（Occupancy=1）触发了更密集的环境监测策略，或者是空调/新风系统在调节温度时的反馈，并非传感器卡死或漂移。其他房间的温度读数变化平缓，符合夏季室内环境温度特征。",
    "4. **无危险事件触发**：厨房烟雾报警器、漏水传感器、一氧化碳报警器均无报警记录；灶具虽在日志中提及但未显示异常开启后无人看管的情况（仅看到灯光开关）。"
  ],
  "key_evidence": [
    "06:34 second_bathroom_light OnOff=True (晨起活动)",
    "07:10 kitchen_light OnOff=True -> 07:22 Off (短暂使用)",
    "15:20-16:30 kids_room_occupancy=1 伴随高频温度上报 (儿童在房内活动)",
    "16:33 front_door_lock LockState=2 (手动上锁，正常安防操作)"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则，确保夜间门窗传感器联动正常即可。"
  ]
}
```

{
  "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": [
    "正常样本浴室活动后很快回到正常房间链路；异常样本长时间停留单一敏感区域。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}


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",

    "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。

    "1. 入户门操作分析：日志显示在 16:22:00 左右，入户门锁执行了手动解锁（LockOperationType=1）并关闭（LockState=2），同时门磁传感器状态变为 False（关闭）。这符合家庭成员回家开门进入室内的正常行为模式。",
    "2. 室内活动连贯性：紧随入户门开启后，玄关、餐厅、主卧等区域的运动传感器相继被触发（15:40-16:30期间多次出现 occupancy=1），且儿童房灯光在 16:27 开启，表明有人在家活动，与回家场景逻辑一致。",
    "3. 环境数据正常：温度传感器读数在 23.6°C - 24.4°C 之间波动，属于舒适的室内环境温度，无异常升温（火灾风险）或剧烈变化。",
    "4. 无异常留守或危险迹象：厨房灯虽在 16:40 开启，但此前已有人员活动轨迹，且未见灶具长时间无人看管或烟雾报警触发；卫生间漏水传感器无报警。整体行为模式呈现典型的“下班/放学回家”后的居家活动特征。"

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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "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晚间活动规律。",
  "reasoning": [
    "1.  occupancy传感器分析：儿童房运动传感器在16:36显示有人（Occupancy=1），随后在17:00变为无人（Occupancy=0）。这符合儿童短暂进入房间后离开的正常行为模式，且持续时间较短，无滞留风险。",
    "2.  温度数据分析：从14:50到17:35，各房间温度传感器读数呈现缓慢下降趋势（例如客厅从2419降至2346，即约24.2°C降至23.5°C）。这种平缓的降温曲线符合夏季傍晚自然散热或空调系统稳定运行的特征，未见剧烈波动或传感器故障迹象。",
    "3.  灯光与电器状态：次卫灯在16:30开启，厨房灯在16:40开启，这与人员活动（如准备晚餐或清洁）的时间点吻合。没有发现长时间无人却亮灯的情况，也没有发现灶具、烟雾报警器等高危设备的异常触发。",
    "4.  综合判断：日志中展示的是典型的傍晚时段家庭活动场景，包括人员短时移动、照明使用及环境温度自然调节，未发现入侵、火灾、漏水或设备故障等安全隐患。"
  ],
  "key_evidence": [
    "kids_room_occupancy 在 16:36 变为 1，17:00 变为 0，显示短时有人活动。",
    "所有温度传感器读数在 14:50-17:35 期间呈平稳下降趋势，无突变。",
    "kitchen_light 和 second_bathroom_light 的开启时间与人员活动逻辑一致。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控夜间睡眠时段的门窗传感器和运动传感器，以确保夜间安全。"
  ]
}
```

{

  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
