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",
  "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，日志显示为正常的夜间家庭活动及传感器数据上报。",
  "reasoning": [
    "1. 门锁状态分析：22:20:30 入户门传感器显示开启（True），紧接着在 22:20:31 门锁执行了手动上锁操作（LockOperation Manual）并变为锁定状态（LockState=1）。这符合住户回家进门后随手反锁门的正常行为逻辑，且无非法入侵迹象。",
    "2. 人员活动模式分析：运动传感器在玄关、客厅和主卧之间交替触发（如 22:19 玄关/客厅有人，22:40 主卧有人），表明住户在夜间进行正常的居家走动（如从客厅去卧室休息）。次卧和卫生间长时间无人（Occupancy=0），符合睡眠或休息时的预期。",
    "3. 设备状态与数据合理性：空调和灯光的关闭操作（22:20）与人员进入卧室休息的行为一致。温度传感器数值（约 22.4°C - 22.7°C）处于合理的室内舒适温度范围，且变化平缓，无剧烈跳变，排除传感器故障或火灾风险。",
    "4. 综合判断：所有事件序列（进门-开灯/关灯-移动-睡觉）连贯且符合人类行为习惯，未发现异常入侵、设备故障或危险情况。"
  ],
  "key_evidence": [
    "22:20:30 front_door_contact = True 随后 22:20:31 front_door_lock LockState = 1 (Manual Lock)，符合回家反锁行为。",
    "22:19-23:40 期间 occupancy_sensor 在 entrance/living_room/master_bedroom 间有规律切换，次卧/bathroom 持续无人，符合夜间作息。",
    "TemperatureMeasurement 数值稳定在 22.4-22.7 度左右，无异常波动。"
  ],
  "recommended_actions": [
    "无需采取任何行动，系统运行正常。"
  ]
}
```

{
  "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": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "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
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",

    "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",

    "1. **入户门操作分析**：在 23:06:32-23:06:33，记录到入户门传感器状态变为 True（开启），紧接着门锁执行了 Manual 锁定操作并进入 Locked 状态。这符合住户深夜回家进门后反锁门的正常行为逻辑，且无异常闯入迹象（如多次失败尝试或非授权开锁）。",
    "2. **室内活动模式分析**：从 22:15 至 23:06，客厅和卧室的运动传感器持续报告 Occupancy=1，表明住户在客厅和卧室之间活动。23:06 左右，客厅主灯、空调关闭，卧室窗帘完全闭合（CurrentPositionLiftPercent100ths = 10000 表示全开/全关取决于具体实现，但结合关灯动作通常意味着拉上窗帘准备休息），随后卧室灯也关闭。这是一套连贯的“结束晚间活动、准备睡觉”的行为序列。",
    "3. **环境数据稳定性**：温度传感器读数在合理范围内波动（客厅约 22.5°C-22.7°C，卧室约 21.4°C-21.7°C），厨房温度略高（约 22.5°C-22.7°C）可能是由于设备散热或烹饪余热，但未触发烟雾报警器，且数值变化平缓，无突变风险。",
    "4. **卫生间活动**：卫生间运动传感器在 22:31、23:01、23:31 间歇性归零，暗示住户可能短暂进入卫生间，这与夜间居家作息相符，未发现长时间滞留或异常静止（跌倒风险低，因为有后续活动记录）。"

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。

```json

  "is_anomaly": false,
  "confidence": "high",

    "1.  occupancy传感器状态分析：在22:30、23:00和23:30三个时间点，客厅、餐厅、主卧、次卧、儿童房、主卫及玄关的运动传感器均报告 Occupancy = 0（无人）。这符合深夜时段家庭成员处于睡眠状态或静止休息的正常生活规律，不存在非法入侵迹象。",
    "2. 温度数据分析：各房间温度传感器读数在22.45°C至22.74°C之间波动（Matter协议中通常以厘摄氏度为单位，即2245-2274 mK = 22.45-22.74°C）。这种微小的波动属于室内环境温度自然变化范围，且所有数值均在舒适区间内，未出现导致火灾风险的急剧升温或设备故障导致的极端读数。",
    "3. 关键安全设备无告警：日志中未包含烟雾报警器、一氧化碳报警器、漏水传感器或门锁状态的异常事件。厨房灶具、空调等设备也未触发任何紧急停止或故障代码。"
  ],
  "key_evidence": [
    "多个房间运动传感器在深夜时段持续报告 Occupancy = 0，符合夜间休眠模式。",
    "所有温度传感器读数稳定在 22.45°C - 22.74°C 范围内，无剧烈波动或超限。",
    "无任何安防类设备（门锁、报警器等）的异常触发记录。"
  ],
  "recommended_actions": [

## 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。

    "2. 人员活动模式分析：卧室运动传感器在22:15、22:35、22:58等时间点多次触发Occupancy=1，随后在22:35:56、23:05:56、23:35:56变为0。这种高频的‘有人-无人’切换符合用户在床上翻身、起夜或调整睡姿的正常生理行为特征，而非入侵者徘徊（入侵者通常会有更长的持续停留或特定的移动轨迹）。",
    "3. 灯光与设备状态：卧室灯在22:35关闭，随后在22:44短暂开启并调光至Level 31（低亮度），这非常符合用户夜间起夜查看手机或短暂活动的习惯。之后灯光未再频繁开关，符合入睡后的状态。客厅和玄关无异常活动记录。",
    "4. 安全设备状态：厨房烟雾报警器、入户门锁、窗户传感器等关键安防设备在日志片段中未报告任何报警状态（如Tamper、Lock Failure、Smoke Detected等）。漏水传感器也无触发记录。"

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",
  "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，日志显示为正常的夜间居家活动及环境监控数据。",
  "reasoning": [
    "1. 活动模式分析：日志记录了22:15至23:55期间的活动。客厅和卧室的运动传感器多次触发（Occupancy=1），随后在几分钟后消失（Occupancy=0），这符合住户在睡前进行正常活动（如走动、准备休息）的行为模式。卫生间传感器偶尔触发后归零，也属于正常的短暂使用场景。",
    "2. 设备状态一致性：卧室灯在22:24开启（Level=29，低亮度），22:42关闭，这与卧室有人活动的时段吻合，且亮度设置合理，无异常操作。",
    "3. 环境数据稳定性：温度传感器读数在正常范围内波动（客厅约22.6°C-22.7°C，卧室约21.4°C-21.7°C，厨房约22.5°C-22.7°C）。数值变化平缓，无剧烈跳变，表明传感器工作正常，无故障或漂移迹象。",
    "4. 无危险事件迹象：日志中未出现烟雾报警器触发、漏水传感器报警、门窗异常开启或门锁异常操作等高危事件。所有关键安全设备均处于静默/正常状态。"
  ],
  "key_evidence": [
    "客厅和卧室运动传感器呈现典型的‘有人-无人’周期性变化，符合人类活动规律。",
    "卧室灯光在有人活动时开启，无人时关闭，逻辑一致。",
    "各房间温度读数稳定，无异常突变或超出合理范围的值。",
    "无任何火灾、入侵、漏水或设备故障相关的告警日志。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续常规监控，确保传感器电池电量充足以保持数据准确性。"
  ]
}
```

{

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

  "key_evidence": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
