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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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": [

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. 人员活动分析：玄关、客厅、主卧的运动传感器在18:09至22:30期间频繁触发（Occupancy=1），表明住户在家中进行正常的晚间活动（如做饭、休息、走动）。次卧和卫生间长时间显示无人（Occupancy=0），符合正常作息规律。",
    "3. 设备操作分析：厨房灶具在18:10开启，随后洗碗机在19:27开启，这些是典型的晚餐后家务行为。窗户传感器在19:06关闭，可能是为了保温或防虫，属于正常交互。",
    "4. 安全状态检查：烟雾报警器、漏水传感器、入户门锁等关键安全设备在日志中未报告任何报警状态（如SmokeDetected、WaterLeak、LockJammed等）。入户门传感器仅在玄关运动传感器触发时作为背景存在，无非法入侵迹象。"

    "2. 设备操作行为正常：22:40左右，客厅主灯和空调被关闭，主卧窗帘完全闭合（CurrentPositionLiftPercent100ths = 10000 表示关闭/遮挡），主卧灯光关闭。这些是典型的睡前准备动作，旨在营造睡眠环境并节约能源。",

    "4. 后续活动持续正常：22:46之后，儿童房、客厅、玄关等区域再次检测到人体存在，可能是其他家庭成员仍在活动或之前的人员在房间内轻微移动，整体时间序列连贯，无异常中断或危险信号。"

## 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": [

}
```

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. **人员活动模式合理**：运动传感器（Occupancy）在客厅、餐厅、主卧、儿童房和玄关之间频繁切换且数值为1，表明家庭成员在晚间活跃于公共区域和卧室，符合正常生活作息。次卧和主卫偶尔显示无人（0），也符合预期。",
    "3. **环境数据稳定**：温度传感器读数在22.4°C至22.6°C之间波动，属于室内舒适温度范围，无剧烈变化暗示设备故障或极端环境事件（如火灾导致的温度骤升）。",
    "4. **无危险设备异常**：厨房烟雾报警器、漏水传感器、灶具等关键安全设备在日志期间未触发任何告警或异常状态。空调和灯光的开关操作与人员活动位置基本对应，无长时间无人却开启高能耗设备的异常情况。"

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。

  "threat_description": "检测到夜间家庭成员在卧室、卫生间及公共区域的活动轨迹，符合正常的睡前洗漱或起夜行为模式，未发现安全威胁。",
  "reasoning": [
    "1. 活动路径分析：日志显示从22:25开始，主卧（master_bedroom）有人活动，随后约2分钟后主卫（master_bathroom）检测到人员进入，接着玄关、客厅、餐厅、儿童房等区域相继检测到人员存在。这种‘卧室->卫生间->其他房间’的流动顺序符合典型的睡前洗漱、喝水或查看家中情况的行为逻辑。",
    "2. 时间窗口合理性：所有活动集中在22:25至23:09之间，属于正常的晚间休息前时段。次卧（second_bedroom）传感器显示Occupancy=0，表明该房间无人，符合预期。",
    "3. 重复性验证：日志中出现了三组高度相似的时间序列（22:25-22:30, 22:45-22:50, 23:05-23:10），每组间隔约20分钟。这可能表示住户在睡前进行了多次短暂活动（如检查门窗、调整空调、再次确认孩子情况等），或者是智能家居系统对持续存在的 occupancy 状态进行的周期性心跳/刷新上报。无论哪种情况，均未表现出入侵者快速移动或异常滞留的特征。",
    "4. 排除入侵特征：入侵通常表现为深夜突然出现在非居住区（如阳台、厨房窗户）或长时间在无人房间徘徊。此处活动主要集中在居住核心区（卧室、卫浴）及连接通道，且无门锁异常开启记录，故判定为正常家庭内部活动。"

## 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",

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。

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",

  ],
  "recommended_actions": [

```

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。

    "3. 环境数据稳定：温度读数在合理范围内波动（客厅约22.4-22.8°C，卧室约21.4-21.8°C），且随时间缓慢变化，无剧烈跳变，表明传感器工作正常，未发生漂移或故障。",
    "4. 关键安全设备无报警：日志中未出现烟雾报警器、漏水传感器、门窗非法开启或门锁异常操作等事件，厨房灶具和洗碗机也无相关状态变更，排除火灾、水患及入侵风险。"

## 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，日志显示为正常的晚间家庭活动及环境监控数据。",
  "reasoning": [
    "1. **门锁状态分析**：22:17:24 记录了一次入户门的“手动上锁”操作（LockOperationType=0），且随后门传感器显示关闭（StateValue=True）。这符合住户在夜间或离家前检查门锁的安全习惯，属于正常行为，非非法入侵迹象。",
    "2. **人员活动模式**：运动传感器（Occupancy Sensor）在客厅、玄关和主卧之间频繁切换（如21:58-23:18期间多次触发），表明家中有人员在正常走动。次卧和卫生间长时间无活动（Occupancy=0），符合夜间休息时的分布规律。",
    "3. **环境参数稳定性**：温度传感器读数在22.4°C至22.7°C之间波动，变化幅度极小且符合室内恒温特征，未发现火灾（烟雾报警器未报警）或设备故障导致的异常温升。",
    "4. **无危险设备操作**：厨房灶具、烟雾报警器、漏水传感器等关键安全设备在日志时段内无任何告警或异常触发记录。"
  ],
  "key_evidence": [
    "front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Manual) - 确认是用户主动上锁",
    "entrance_occupancy / living_room_occupancy 周期性触发 - 证明有人在家正常活动",
    "kitchen_smoke_co_alarm 无报警事件 - 排除火灾风险",
    "Temperature values stable around 22.5C - 排除环境异常"
  ],
  "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，确保夜间自动布防功能正常开启。"
  ]
}
```

{
  "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。"
  ]
