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",

    "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. 人员活动分析：日志显示全天大部分时间（05:00-19:00）各房间运动传感器（Occupancy Sensor）均报告为 0（无人），这符合家庭成员外出工作或上学后的常态。仅在早晨 07:00 厨房灯开启，傍晚 18:30-18:40 客厅和厨房灯开启，这些时间点与典型的下班回家、准备晚餐或休息的作息高度吻合。",
    "2. 温度数据分析：室内温度从清晨约 24.4°C 逐渐上升至下午高峰约 25.5°C，随后在傍晚降至 22.8°C 左右。这种缓慢的自然升温降温曲线符合夏季白天房屋受热、傍晚散热的环境物理规律，且无剧烈波动，表明空调系统可能处于关闭或节能模式，或者房屋保温良好，不存在设备故障导致的异常温升。",
    "3. 关键设备状态检查：重点关注的厨房灶具（cook_surface）、烟雾报警器（smoke_co_alarm）、漏水传感器（water_leak_detector）在日志中均未触发任何告警或异常状态变化。入户门锁（door_lock）也未记录到非法开锁尝试。",
    "4. 结论：综合光照、温度及 occupancy 数据，未发现入侵、火灾、漏水或设备故障迹象，行为模式正常。"
  ],
  "key_evidence": [
    "全天 OccupancySensing.Occupancy 多为 0，仅早晚有短暂灯光操作，符合离家/归家模式。",
    "TemperatureMeasurement.MeasuredValue 呈现平滑的自然昼夜变化趋势（24.4°C -> 25.5°C -> 22.8°C），无突变。",
    "厨房 cook_surface 和 smoke_co_alarm 无任何异常触发记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则设置，确保夜间安防传感器正常工作。"

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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。

{
  "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: 日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "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": [
    "继续监测，无需立即处置。"
  ]
}

{
  "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。

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。

    "3. 排除异常指标：卫生间传感器仅在22:50和23:20显示无人（Occupancy=0），暗示之前有人使用过，符合夜间如厕习惯。没有发现门锁异常开启、烟雾报警、漏水或长时间静止（跌倒风险）等危险信号。所有设备状态均在正常逻辑范围内。"

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：

## 任务
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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2: ...",

    "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": "检测到独居老人在夜间频繁起夜，活动模式规律且符合正常生理行为，未发现安全威胁。",
  "reasoning": [
    "1. 分析时间窗口：所有事件发生在 2026-07-01 的 22:45 至 23:28 之间，属于深夜时段。对于独居老人而言，夜间起床（起夜）是常见的生理需求。",
    "2. 分析活动路径与频率：日志显示卧室、厨房、客厅、玄关的运动传感器在约每 15-20 分钟内被触发一次（22:45, 22:50, 23:05, 23:08...），且卫生间 occupancy 传感器先变为 1（隐含在之前的逻辑中，虽然日志只记录了离开为0的时刻，但结合其他房间活跃，可推断有人活动）。这种高频次的短距离移动（卧室->卫生间/厨房->返回）符合老年人夜间如厕或喝水的习惯。",
    "3. 排除异常风险：没有检测到入户门锁开启、窗户打开、烟雾报警或漏水等危险信号。老人的活动轨迹局限在室内主要生活区域，未出现长时间静止（跌倒风险低）或剧烈无序运动。这种规律的夜间活动模式在独居老人家庭中属于正常行为。"
  ],
  "key_evidence": [
    "22:45 - 23:28 期间，卧室、厨房、客厅、玄关等多个区域传感器交替触发，表明有人在室内持续活动。",
    "卫生间 occupancy 传感器在 22:50 和 23:20 记录到 'Occupancy = 0'，暗示之前有人进入并离开，符合如厕后离开的特征。",
    "活动时间间隔规律（约15-20分钟一次循环），无门锁异常开启或火灾/泄漏警报。"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议家属关注老人夜间睡眠质量及起夜频率，若频率过高可能涉及健康隐患（如前列腺问题或糖尿病），可考虑增加夜间地脚灯以预防跌倒。"
  ]
}
```

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

  ],
  "key_evidence": [

## 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",

  ],
  "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。

    "2. 检查关键安全设备状态：日志中仅包含温度传感器（TemperatureMeasurement）和运动传感器（OccupancySensing）的数据。未发现烟雾报警器（smoke_co_alarm）、一氧化碳报警器、漏水传感器（water_leak_detector）或门锁（door_lock）的异常触发记录（如报警值、非法开锁等）。",
    "3. 分析运动传感器模式：厨房、卧室、客厅、玄关的运动传感器在深夜频繁报告 Occupancy=1，这通常是因为 PIR 传感器的默认行为是周期性上报当前状态或存在微小移动（如呼吸、翻身、宠物走动），而非表示有人在进行剧烈活动。特别是卧室传感器持续在线，符合老人在床上休息的状态。",
    "4. 分析温度数据：各房间温度读数（约 21.5°C - 22.7°C）处于舒适且稳定的范围内，无急剧升温（火灾风险）或降温情况。温度数值以整数形式上报（如 2260 代表 22.60°C），符合 Matter 协议标准格式，无传感器漂移或故障迹象。",

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。

    "3. 排除异常特征：没有检测到入侵迹象（如门锁异常开启、窗户被打破）、没有火灾或燃气泄漏报警、没有长时间无活动的健康风险（客厅一直有人）。传感器状态变化逻辑自洽，未发现设备故障或恶意攻击痕迹。"
