## 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。

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

  "reasoning": [
    "1. **入侵风险排除**：入户门传感器（front_door_contact）在07:38显示关闭（False），同时门锁执行了手动解锁操作（LockOperationType=0），且玄关运动传感器（entrance_occupancy）随后检测到有人进入。这符合住户早晨出门或回家的正常行为模式，无强行闯入迹象。",
    "2. **烹饪与火灾风险排除**：厨房灯（kitchen_light）在晚间开启，但日志中未出现灶具（cook_surface）被激活的记录，也未触发烟雾报警器（smoke_co_alarm）。虽然任务描述重点提及kitchen_light，但缺乏伴随的烹饪设备活动或高温/烟雾报警，因此不构成无人看管烹饪或火灾风险。",
    "3. **传感器数据合理性**：温度传感器读数（如2484-2556等）呈现随时间缓慢变化的趋势，符合室内环境温度自然波动特征，无突变或停滞现象，排除了传感器故障（sensor_stuck/malfunction）。",
    "4. **人员活动逻辑一致**：客厅、卧室的运动传感器在夜间大部分时间为0（无人），白天有间歇性活动记录，且各房间活动存在时间差（如先玄关后客厅），符合多人口家庭的正常生活轨迹，无异常静止（abnormal_inactivity）或跌倒（possible_fall）迹象。"
  ],
  "key_evidence": [
    "07:38:22 front_door_contact = False (门关闭) 配合 07:38:24 LockOperation(LockOperationType=0) (手动解锁)，表明是受控的进出行为。",
    "全天无 smoke_co_alarm 触发，且 cook_surface 无激活日志。",
    "TemperatureMeasurement.MeasuredValue 随时间平滑变化，无异常跳变。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的智能家居自动化规则，确保夜间安防模式正常运行。"
  ]
}
```

{

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

## 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",

    "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。

    "2. **室内活动轨迹**：紧随入户动作后，客厅运动传感器在18:25:17触发（Occupancy = 1），客厅主灯和落地灯相继开启，空调启动并设定为制冷模式（System Mode 3）。这表明住户进入客厅区域并进行常规的环境调节，行为连贯且合理。",
    "3. **环境数据一致性**：温度传感器读数在2300-2400之间波动（对应约23.0°C-24.0°C），处于舒适区间，且随空调开启呈现缓慢下降趋势，无异常突变或设备故障迹象。所有卧室传感器均显示无人状态，与主要活动集中在客厅的情况相符。",
    "4. **排除异常模式**：未发现非法入侵特征（如门锁异常开启、非授权时间段的闯入）、火灾风险（烟雾报警器未触发）或设备故障（传感器读数稳定，执行器响应及时）。"

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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": "日志显示为正常的晚间家庭活动模式，包括烹饪、清洁和人员移动，未检测到安全威胁或设备异常。",
  "reasoning": [
    "1. **烹饪行为正常**：厨房灯在17:59开启，灶具(cook_surface)在17:59开启，并在18:40关闭。这符合典型的晚餐准备流程（约40分钟），且结束后灶具已关闭，无未关火风险。",
    "2. **清洁活动正常**：洗碗机(dishwasher)在18:40启动，紧随烹饪结束时间，符合饭后清洗习惯。同时厨房窗户传感器在18:30报告关闭(False)，表明门窗处于安全闭合状态。",
    "3. **人员活动逻辑一致**：客厅运动传感器(living_room_occupancy)在16:22至18:42期间多次报告有人(1)，与灯光开启时间和烹饪/休闲活动吻合。卧室和玄关传感器报告无人(0)，符合家庭成员集中在客厅和厨房的常态分布。",
    "4. **数据完整性检查**：虽然部分温度传感器在特定时间点返回None值（如18:00和18:41的厨房温度），但这通常是由于设备上报间隔或瞬时通信丢包导致的，随后数值恢复正常，不构成传感器故障或漂移的持续证据。"
  ],
  "key_evidence": [
    "kitchen_cook_surface OnOff=True (17:59) -> False (18:40): 烹饪时长合理且已关闭。",
    "kitchen_dishwasher OnOff=True (18:40): 饭后正常启动清洁程序。",
    "living_room_occupancy=1 (16:22-18:42): 客厅持续有人活动，与灯光和电器使用同步。",
    "kitchen_window_contact=False (18:30): 窗户保持关闭，排除入侵或天气风险。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议定期检查温度传感器None值的频率，若频繁出现可考虑更换电池或检查网络信号。"
  ]
}
```

{
  "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": [
    "正常样本回家后有客厅/厨房过渡活动；异常样本直接进入卧室。"
  ],
  "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",

  ],
  "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，日志显示为正常的晚间回家、开灯、开启空调及准备晚餐的家庭活动。",

    "1. **入户与安防状态正常**：17:56 门锁执行手动解锁（LockOperationType=1），随后门磁传感器显示关闭（StateValue=False），表明住户正常开门进入并关门。18:20 门磁再次显示关闭，符合居家常态。无非法入侵迹象。",
    "2. **人员活动轨迹合理**：17:31 玄关运动传感器激活，17:56 客厅运动传感器激活，18:11/18:31 玄关再次有活动记录，结合主卧和次卧的 occupancy 变化，显示住户在客厅和卧室之间移动，符合晚间休息或活动的行为逻辑。",
    "3. **设备操作符合生活场景**：17:56 住户回家后打开客厅灯和空调（SystemMode=3 通常为制冷或制热，结合温度下降趋势推测为制冷或维持舒适温度）。18:23 厨房灯亮起，18:23:30 灶具开启，这是典型的准备晚餐行为。",
    "4. **烹饪安全性评估**：虽然灶具在 18:23 开启，但日志截止时间为 18:45，仅持续约 22 分钟。对于晚餐准备而言，这是一个非常短且合理的时长，尚未达到“无人看管烹饪”（unattended_cooking）通常定义的长时间离开阈值（通常需结合后续无活动或烟雾报警判断）。且期间厨房温度传感器读数波动（18:24 为 None，可能因高温或故障，但随即恢复），未见烟雾报警器触发。",
    "5. **环境数据一致性**：室内温度从 16:40 的 ~23.7°C 逐渐下降至 18:45 的 ~22.9°C，这与开启空调（17:56）后的降温趋势一致，设备运行正常。"

## 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",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"

  "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。"
  ]
}

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。

    "1. 入户门操作分析：22:30:24 门传感器显示开启 (True)，紧接着 22:30:25 门锁执行了手动上锁操作 (LockOperation Type=0, LockState=1)。这符合住户回家进门后反锁或离家前检查门锁的正常行为逻辑，且发生在深夜，属于常规安防动作。",
    "2. 人员活动模式分析：22:25-23:10 期间，儿童房、主卧、餐厅、玄关和客厅的运动传感器多次触发 (Occupancy=1)。这表明家庭成员在深夜仍在进行正常的居家活动（如洗漱、休息准备、走动等），并非异常入侵或长时间静止的异常情况。",
    "3. 设备状态一致性：客厅灯和空调在 22:30 关闭，与运动传感器的活跃状态结合看，可能是住户离开客厅区域去其他房间（如卧室）休息，符合夜间作息规律。没有发现烟雾报警、漏水或门窗异常开启未关等危险信号。"

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": [
    "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。

    "1. 温度数据解读：日志中的温度传感器数值（如2241, 2144等）符合Matter协议TemperatureMeasurement集群的编码格式（单位为0.01°C）。换算后分别为22.41°C、21.44°C等，处于人体舒适且正常的室内温度范围，无过热或过冷风险，排除火灾或极端环境隐患。",
    "2. 人员活动模式分析：在21:55至23:39期间，卧室、客厅、厨房、玄关及卫生间的运动传感器频繁触发（Occupancy=1），表明住户在家中多处走动。这种多房间的活动轨迹符合老年人晚间洗漱、休息前准备或轻微活动的正常行为特征。",
    "3. 卫生间异常值澄清：虽然卫生间运动传感器在22:15、22:45、23:15显示为0（无人），但这与整体活跃模式并不矛盾。考虑到时间间隔（约30分钟一次归零），这极可能是住户短暂离开卫生间返回其他房间，或者是传感器因老人动作幅度小导致的间歇性漏报/误报，而非长时间静止不动（跌倒风险通常伴随长时间无活动且无其他区域活动，此处其他区域活动频繁）。",
    "4. 无入侵迹象：入户门传感器和门锁未在日志中报告异常开启或非法操作，所有活动均发生在室内，且时间集中在晚间，符合居家作息。"

    "卫生间传感器周期性归零，结合其他房间持续有人活动，判断为正常的人员移动而非滞留或意外。"
  ],
  "recommended_actions": [
    "无需立即干预，继续保持常规监控。",
    "建议定期校准卫生间运动传感器的灵敏度，以减少因老人动作缓慢导致的误报或漏报，提高跌倒检测的准确性。"
