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，日志显示为正常的家庭晚间活动模式（回家、开灯、开空调、烹饪准备）。",
  "reasoning": [
    "1. **入户行为分析**：在 18:04:00，入户门锁执行了手动上锁操作 (LockState=2)，紧接着入户门传感器显示关闭 (False)，玄关和客厅运动传感器随即激活。这符合住户下班回家后反锁大门并进入室内的正常行为逻辑。",
    "2. **环境控制响应**：入户后不久 (18:04:17)，客厅灯光开启，且空调启动并设置为制冷模式 (SystemMode=3)。结合此时段室内温度约为 23-24°C (Matter协议中通常单位为0.01摄氏度，即23.77°C左右)，开启空调降温是合理的舒适性生活行为。",
    "3. **厨房活动关联**：在 18:24:00，厨房灯开启，随后餐厅和厨房区域出现人员活动迹象。这与傍晚时分准备晚餐的时间点吻合，属于正常的家庭生活节奏。",
    "4. **无异常指标**：未检测到烟雾报警、漏水报警或非法入侵尝试（如多次开锁失败）。所有设备状态变化均有对应的人员活动或环境调节需求支撑，不存在孤立的异常状态。"
  ],
  "key_evidence": [
    "[18:04:00] front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) - 确认住户手动反锁，表明有人在家。",
    "[18:04:17] living_room_ac | Thermostat.SystemMode = 3 - 空调启动制冷，符合晚间回家后的舒适度调节。",
    "[18:24:00] kitchen_light | OnOff.OnOff = True - 厨房亮灯，预示晚餐准备开始，与时间线一致。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持常规监控，确保门窗传感器电池电量充足以维持准确的状态报告。"
  ]
}
```

{
  "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。"
  ]

## 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",

    "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. 温度数据分析：Matter协议中 TemperatureMeasurement.MeasuredValue 通常以厘氏度（celsius * 100）为单位。例如 2485 代表 24.85°C。日志中的温度值在 22.93°C 至 25.52°C 之间波动，处于舒适的室内环境温度范围内，无极端高温（火灾风险）或低温（管道冻结风险）。温度变化平缓，符合自然热惯性，无传感器漂移或故障迹象。",
    "3. 安全设备状态：入户门传感器（front_door_contact）和门锁（front_door_lock）仅在早晨07:23左右有短暂的开关和锁定操作，之后全天保持关闭/锁定状态（隐含在后续无开门事件中），未发现非法入侵、尾随或锁具故障迹象。烟雾报警器、漏水传感器等安全设备在日志期间未触发任何警报事件。"

  "key_evidence": [
    "8月13-14日早晨07:00-09:00期间，主卧和客厅 occupancy 为 1，随后变为 0，符合居民起床后外出的正常作息。",
    "8月15日所有房间 occupancy 均为 0，且温度稳定下降，表明房屋处于无人且封闭状态，无异常闯入。",
    "所有温度读数（如 2485, 2516, 2326 等）换算后均在 23-25°C 舒适区间，无火灾或设备过热风险。",
    "门锁仅在早晨有一次手动解锁/上锁记录，无多次失败尝试或非授权时间段的开启记录。"
  ],

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。

  "reasoning": [
    "1. **活动模式符合常理**：从17:00开始，客厅 occupancy 传感器持续检测到有人（Occupancy=1），随后卧室、厨房、玄关等区域也陆续出现人员活动迹象。这符合独居老人在傍晚回家、准备晚餐、休息的日常作息规律。",
    "2. **设备状态逻辑自洽**：客厅灯在19:00开启，20:24调暗（LevelControl.CurrentLevel = 18），21:30关闭。这种‘开灯-调暗-关灯’的操作序列是典型的睡前准备行为，表明住户意识清醒且能正常操作智能家居设备。",
    "3. **环境数据稳定**：各房间温度传感器读数在合理范围内波动（如客厅22-23°C，卧室21-22°C），未见剧烈跳变或异常高温/低温，排除了火灾或极端天气导致的设备故障风险。",
    "4. **安防事件正常**：20:53左右入户门传感器和门锁状态变化（LockState=1通常表示已锁定，Contact=True可能表示门被触发或状态更新），结合后续卧室灯光关闭，推测为住户归家后锁门并回房休息，属于正常安防闭环。"

## 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",

  ],
  "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. **环境控制逻辑合理**：18:12 回家后不久（18:12:27）开启客厅空调，此时室内温度约 23°C 左右（传感器数值需除以100，即23.56°C->23.12°C），开启空调降温符合夏季傍晚的生活习惯。19:00 开启客厅主灯，符合夜间照明需求。",
    "3. **厨房与家务活动正常**：18:19 灶具开启，19:30 洗碗机启动，表明进行了晚餐烹饪和清洁工作。虽然灶具开启时间较长，但期间有人员在厨房附近活动（通过其他传感器间接推断或虽无直接厨房人感但结合生活常识判断），且未检测到烟雾报警，属于正常的无人值守烹饪场景（如炖煮），非危险状态。",
    "4. **数据解读正确**：温度传感器数值（如 2356）对应 Matter 协议中的厘度（centi-degrees），即 23.56°C，处于舒适室温范围，无过热或传感器故障迹象。"

    "19:00:00 living_room_light_1 OnOff=True: 晚间开灯，符合作息。",
    "19:30:05 kitchen_dishwasher OperationalState=1: 饭后清洗餐具，正常家务流程。"

## 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，日志显示为正常的傍晚家庭活动模式（烹饪、清洁、休闲）。",
  "reasoning": [
    "1. **烹饪行为分析**：厨房灶具 (kitchen_cook_surface) 在 17:45 开启，于 18:47 关闭，持续约1小时。随后洗碗机 (kitchen_dishwasher) 立即启动。这符合典型的晚餐准备及餐后清理流程，属于正常的人类行为习惯，不存在无人看管的风险。",
    "2. **环境与安全状态**：在烹饪期间，烟雾报警器 (smoke_co_alarm) 未触发任何报警事件；厨房窗户传感器 (kitchen_window_contact) 在 18:47 显示关闭状态（StateValue=False，通常Matter中False表示Closed/Secure），表明门窗处于安全闭合状态，无入侵迹象。",
    "3. **人员活动轨迹**：客厅运动传感器 (living_room_occupancy) 在 16:40-18:40 期间多次报告有人存在，与晚间居家活动时间吻合。卧室和玄关传感器均报告无人（Occupancy=0），符合家庭成员集中在客厅和厨房活动的逻辑。",
    "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`（如 17:46, 18:48），但这发生在设备操作（开火、启动洗碗机）或网络波动间隙，且后续读数恢复正常范围（22-23°C左右，注意Matter协议中温度值通常为摄氏度*100，即2300代表23.00°C），未见持续的传感器故障或漂移特征。"
  ],
  "key_evidence": [
    "kitchen_cook_surface OnOff=True (17:45) 后接 Off=False (18:47)，伴随 dishwasher 启动，形成完整的烹饪-清洁闭环。",
    "smoke_co_alarm 全程无报警记录。",
    "living_room_occupancy 在傍晚时段持续为 1，符合居家常态。",
    "temperature_sensor 数值在 2290-2370 (22.9-23.7°C) 之间波动，属正常室温范围。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议定期检查厨房烟雾报警器的电池状态以确保长期可靠性。"
  ]
}
```

{
  "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: ...",

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

    "推理步骤 2: 更关键的异常发生在 19:48，当用户关闭灶具后仅 2 分钟，厨房温度传感器的 MeasuredValue 变为 None（无数据）。这表明传感器可能已完全失效、通信中断或被遮挡，导致烟雾报警器失去关键的环境温度参考数据。",
    "推理步骤 3: 虽然窗户传感器在 19:47 检测到打开状态（可能是通风），但结合温度传感器的异常行为，系统无法确认厨房内部是否存在过热或烟雾积聚的风险，构成了潜在的安全盲区。"
