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. 人员活动轨迹：运动传感器显示人员在卧室、客厅、卫生间之间有规律的活动记录（Occupancy=1/0切换），符合晚间休息前的洗漱、休闲习惯。卫生间传感器多次归零（0）表示无人进入，符合逻辑。",
    "4. 环境数据稳定性：各房间温度传感器读数在合理范围内波动（卧室~21-22°C，客厅~22-23°C，厨房因烹饪略高），无突变或异常漂移。夜间21:46后窗帘关闭，门锁再次锁定（LockOperationType=0），符合睡前安防设置。",

    "推理步骤 2: 对比其他房间，卧室和客厅的温度传感器在整个时间段内持续稳定地报告数值（例如卧室从 2220 降至 2147，符合夜间降温规律），证明网络连通性和传感器供电基本正常。厨房传感器的间歇性 'None' 排除了全屋网络故障的可能性。",

    "3. 排除异常风险：所有关键安全设备（烟雾报警器、燃气/灶具、门锁）均无告警记录；门窗传感器状态未在日志中显示异常开启；时间处于晚间休息时段，活动范围集中在生活区，符合常规生活习惯，无入侵或火灾迹象。"

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。

## 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": [

    "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",

    "1. **入户门操作分析**：在 22:10:15-22:10:16，记录到入户门传感器状态变为 True（开启），紧接着门锁执行了 Manual 锁定操作（LockState=1）。这一序列符合住户回家开门后随即反锁或离开时锁门的正常行为逻辑，且发生在晚间时段，无异常闯入迹象。",
    "2. **人员活动模式分析**：运动传感器（Occupancy）在客厅、玄关、餐厅、主卧、儿童房等多个区域频繁触发（值为1），表明家庭成员在晚间进行正常的居家活动（如走动、休息）。次卧和主卫的运动传感器间歇性归零，符合无人居住或短暂离开的特征，整体活动轨迹连贯且合理。",
    "3. **环境与设备状态分析**：温度读数在 22.4°C - 22.6°C 之间波动，属于室内舒适温度范围，无火灾或极端环境风险。客厅空调在 22:10:04 关闭，随后灯光也陆续关闭（22:10:00, 22:10:20），窗帘位置固定，显示住户正在执行睡前关灯、关空调的常规就寝程序。",
    "4. **排除其他风险**：未发现烟雾报警器触发、漏水传感器报警、灶具长时间未关闭等危险信号；门锁操作来源标记为 Manual，非远程强制解锁，排除了凭证泄露导致的远程入侵风险。"

## 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",

    "关键证据2"
  ],
  "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。

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. 逻辑推理：在深夜时段，家庭成员通常处于睡眠或静止状态，运动传感器检测不到活动是预期内的正常现象。没有检测到异常入侵迹象（如非休息时间有人移动）或设备故障（如传感器持续报错），因此判定为安全状态。"

## 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"

}
```

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
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: ...",

    "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。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在设备状态变更（灶具关闭、洗碗机开启）期间出现数据丢失和异常跳变，表明传感器可能发生故障或通信中断。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-01T18:04:00，厨房温度传感器报告了 None 值，这通常表示传感器未响应、电池耗尽或连接断开。",
    "推理步骤 2: 随后在 18:10:00 和 18:15:00，传感器读数从正常的 23xx (约 23°C) 突然跳变为 2323 和 2308，虽然数值看似合理，但紧接着在 18:41:00 灶具关闭后，读数开始持续缓慢下降且波动异常（2287 -> 2283 -> 2278...），这种下降速率与室温自然变化不完全匹配，且中间穿插了多次无明确触发源的微小波动。",
    "推理步骤 3: 结合上下文，当用户操作厨房电器（关闭灶具、开启洗碗机）时，温度传感器未能提供连续稳定的监测数据（特别是 18:04 的 None），这属于典型的传感器故障（Sensor Malfunction），可能导致无法准确监控厨房过热风险或火灾预警失效。"
  ],
  "key_evidence": [
    "[2026-08-01T18:04:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None",
    "[2026-08-01T18:41:00] kitchen_cook_surface | OnOff.OnOff = False 之后温度读数出现非线性的快速下降趋势"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理连接和电池状态。",
    "尝试重启该传感器设备以恢复通信。",
    "在修复前，建议人工定期手动检查厨房环境温度，以防发生火灾等安全隐患。"

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：

  "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。

    "3. 门禁与入侵检查：入户门传感器（front_door_contact）仅在20:49:12触发一次（True），随后无持续开启或反复开关记录，结合玄关运动传感器在该时段前后均有活动，推测为住户正常的进出或取物行为，而非非法入侵。",
    "4. 设备功能验证：卧室灯在20:49短暂开启后关闭，属于正常的照明操作；温度传感器读数随时间缓慢变化（如卧室从22.15°C降至21.44°C），符合夜间自然降温规律，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。
