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",

    "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. 人员活动轨迹分析：从18:00开始，多个房间（主卧、儿童房、客厅）的运动传感器陆续触发，表明家庭成员正在家中活动。18:30厨房灶具开启，随后在18:53关闭，持续约23分钟，符合正常的晚餐烹饪时长，未发现无人看管烹饪的风险。",
    "3. 照明与设备控制：19:00客厅主灯开启，21:30关闭，符合晚间居家照明习惯。餐厅灯在18:53开启（可能伴随用餐），19:50关闭，逻辑连贯。入户门传感器在19:03、19:35等多次触发，结合室内人员活跃情况，推测为家人进出或查看门口，未见非法入侵特征（如深夜独自触发且无室内响应）。",
    "4. 综合判断：所有关键事件（烹饪、照明、人员移动、温控）均呈现合理的时序关联和行为逻辑，无冲突、无遗漏的安全警报（如烟雾报警未触发，漏水传感器无报警），整体环境安全。"
  ],
  "key_evidence": [
    "kitchen_cook_surface OnOff=True (18:30) 后于 18:53 变为 False，烹饪行为完整且有人看管。",

    "各房间温度传感器读数稳定在 22.4°C - 23.6°C 区间，无异常漂移。",
    "多房间 occupancy_sensor 频繁触发，显示家庭成员在客厅、餐厅、卧室间正常流动。"
  ],
  "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
请从下面 3 天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。

{
  "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: 正常样本仍有零星厨房活动；异常样本连续多天完全缺失相关使用。"
  ],
  "key_evidence": [
    "正常样本仍有零星厨房活动；异常样本连续多天完全缺失相关使用。"
  ],
  "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": [
    "正常样本仍有零星厨房活动；异常样本连续多天完全缺失相关使用。"
  ],
  "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
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": "未检测到安全威胁，日志显示为正常的夜间无人居住状态及偶发的灯光操作。",
  "reasoning": [
    "1. **人员活动分析**：从17:00到20:30，所有房间（客厅、主卧、次卧、卫生间、玄关）的运动传感器（Occupancy Sensor）持续报告值为0，表明房屋内无人活动。这符合傍晚至夜间家庭成员休息或外出的正常行为模式。",
    "2. **环境数据一致性**：温度传感器读数在22.6°C - 23.5°C之间波动（Matter协议中通常以0.01摄氏度为单位，即2355代表23.55°C），数值变化平缓且符合室内环境温度特征，无剧烈跳变，排除传感器故障或极端天气入侵风险。",
    "3. **设备状态逻辑**：仅在19:00有一次客厅主灯开启（OnOff=True），并在14分钟后于21:30关闭。虽然中间有长时间间隔，但考虑到全屋无人的背景，这可能是自动化场景触发（如定时开关）、误触或用户短暂进入后离开。由于没有伴随其他异常（如门锁开启、烟雾报警、漏水等），且最终状态回归平静，不构成即时威胁。",
    "4. **综合判断**：缺乏入侵迹象（门锁未异常开启、窗户未打开）、缺乏火灾/燃气风险（无烟雾/CO报警）、缺乏健康风险（无跌倒检测或长时间静止警报）。整体表现为安全的静态监控状态。"
  ],
  "key_evidence": [
    "所有区域运动传感器在17:00-20:30期间持续返回 Occupancy = 0",
    "温度读数稳定在舒适区间 (22.6-23.5°C)，无异常波动",
    "仅发生一次短暂的客厅灯光开启事件，随后系统恢复无人静止状态"
  ],
  "recommended_actions": [
    "无需立即干预，保持当前监控策略即可。",
    "若该灯光开启行为非用户预期，可检查是否配置了错误的自动化规则或存在智能音箱/语音助手的误唤醒情况。"
  ]
}
```

{
  "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": [
    "正常样本只是晚间一次开关灯；异常样本短时间内重复高频操作。"

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。

```json

    "1. **入侵检测分析**：入户门传感器（front_door_contact）在07:10和17:58显示关闭（BooleanState=False），对应门锁上锁（LockState=1）及玄关运动传感器激活，符合住户离家和回家的正常行为模式。未发现非授权时段的异常开启记录。",
    "2. **烹饪安全分析**：厨房灶具（kitchen_cook_surface）仅在18:53有一次短暂的关闭记录，且此前无长时间开启导致过热或烟雾报警器的触发日志。结合厨房温度传感器读数平稳（约23°C-25°C），排除火灾或未看管烹饪风险。",
    "3. **传感器数据合理性**：温度传感器数值（如2472, 2505等）呈现典型的Matter协议原始值特征（通常为0.01°C单位，即24.72°C, 25.05°C），数值随时间缓慢变化，符合室内环境温度波动规律，无传感器卡死或漂移迹象。",
    "4. **人员活动逻辑**：客厅、主卧、玄关的运动传感器激活时间与灯光开关、空调启动等行为高度关联（如17:58回家开空调，18:40开厨房灯），表明系统运行正常，无异常静默或突发异常活动。"
  ],
  "key_evidence": [

    "温度传感器读数在合理范围内（约23-25°C）平滑变化，无突变或停滞。",
    "各房间运动传感器与灯光/家电操作存在合理的因果时序关系。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期校准温度传感器以确保读数精度（虽然目前看来工作正常）。"

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 3 天的设备活动记录。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": "未检测到安全威胁或异常行为，所有设备活动符合正常的家庭作息规律。",
  "reasoning": [
    "1. **入侵风险排除**：入户门锁（front_door_lock）仅在早晨07:31和傍晚18:27出现手动解锁记录，且伴随门磁传感器（front_door_contact）状态变为False（开门），随后在合理时间内关闭。这符合典型的“离家”和“回家”模式，无非法闯入迹象。",
    "2. **人员活动正常**：客厅运动传感器（living_room_occupancy）在夜间（如23:48、23:35）偶尔触发为1，可能是住户在客厅短暂活动或设备误报，但随后很快恢复为0，且白天有持续的 occupancy=1 记录，表明住户在家活动正常，无长时间静止不动导致的健康担忧。",
    "3. **烹饪与火灾风险低**：厨房灯（kitchen_light）在清晨06:47开启，晚间18:48/19:03开启，符合做饭时间。日志中未检测到烟雾报警器（smoke_co_alarm）报警，也未发现灶具（cook_surface）长时间无人看管（通过 occupancy 和灯光结合判断，厨房区域有人活动）。",
    "4. **环境数据稳定**：温度传感器读数随时间缓慢变化，符合昼夜温差规律（白天约24-25°C，夜间降至22-23°C左右），无突变或传感器故障迹象。"
  ],
  "key_evidence": [
    "入户门锁仅在07:31和18:27手动解锁，对应正常的出门和回家时间。",
    "客厅运动传感器在夜间偶发触发后迅速复位，且白天有持续活动记录，符合正常居家生活。",
    "厨房灯光开启时间与常规晚餐/早餐准备时间吻合，且无烟雾报警。",
    "室内温度变化平缓，无异常波动。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则，继续监控夜间长时间无活动的情况以防跌倒等意外，但目前数据未见明显异常。"
  ]
}
