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",

    "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. 分析数据范围：Matter协议中TemperatureMeasurement.MeasuredValue通常以0.01°C为单位上报。日志中大部分数值在2358-2558之间，对应室温约23.6°C-25.6°C，符合正常家庭环境特征。",
    "2. 识别异常点：在[2026-08-08T14:05:00]时刻，living_room_temp_sensor上报值为-500，这在物理上是不可能的（除非极寒环境且传感器未校准，但结合前后文2430和2440来看，这显然是错误数据）。",
    "3. 观察趋势异常：在异常点前后，温度读数呈现非自然的剧烈波动。例如从14:00的2430骤降至14:05的-500，随后在14:10回升至2440，14:15又升至2475。这种短时间内的大幅震荡不符合热惯性规律，表明传感器可能存在间歇性故障、电池电量不足导致信号不稳定，或者内部ADC转换错误。",
    "4. 排除其他因素：同一时间段内，厨房和其他房间的温度传感器读数变化平缓且合理（如kitchen从2497降至2457），说明并非全屋环境突变，而是特定设备问题。"

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",

    "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
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",
  "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。

  "threat_type": "sensor_malfunction",
  "threat_description": "门窗传感器状态与窗帘位置矛盾",
  "reasoning": [

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：住户在离开卧室后，于无人状态下打开客厅窗户并关闭窗帘，随后门锁被手动操作且门传感器状态异常。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 07:40 左右，入户门锁 (front_door_lock) 发生了手动上锁操作 (LockOperationType=1)，紧接着 (31 秒后) 入户门接触传感器 (front_door_contact) 报告状态为 True (通常表示门已打开或处于非闭合安全状态，取决于具体定义，但结合上下文更可能是门被打开或传感器误报导致状态翻转)。",
    "推理步骤 2: 关键异常发生在 09:10-09:12。此时 living_room_occupancy 持续为 0 (无人)，living_room_window_contact 先变为 True (窗户打开)，随后仅过 9 秒 (09:12:09) 又变为 False (窗户关闭)。这种极短时间内‘开窗 - 关窗’的动作模式，在无人居住的情况下极不自然，不符合正常通风习惯，更像是有人进入室内操作后迅速撤离或试图掩盖痕迹。",
    "推理步骤 3: 结合 07:40 的出门记录和 09:10 的窗户异常动作，存在一种可能性：有人在住户出门后（或趁其不在时）进入了房屋，打开了窗户（可能为了制造噪音、通风或作为进出通道），并在短时间内关闭了窗户和窗帘 (09:15 窗帘位置仍为 0，即完全拉下/关闭)，试图恢复现场。虽然日志未直接显示窗户再次打开，但‘无人状态下快速开关窗’是典型的入侵前兆或入侵过程中的行为特征。",
    "推理步骤 4: 此外，厨房温度传感器读数极高 (约 254°C，实际应为 25.4°C 但单位缺失或漂移严重)，若确认为真实高温则伴随火灾风险；但考虑到所有房间温度同步偏高且变化趋势一致，更有可能是传感器校准问题或数据格式误解。然而，相比于温度数据的歧义，窗户和门锁的行为逻辑矛盾构成了明确的物理入侵证据链。"
  ],
  "key_evidence": [
    "09:10:00 至 09:12:00 期间，living_room_window_contact 在无人 (Occupancy=0) 状态下发生 'True -> False' 的快速翻转，暗示有人短暂开启并关闭了窗户。",
    "07:40:22 门锁手动上锁后，07:40:31 门传感器立即报告 StateValue=True，可能存在门未关严或非法开启后的状态重置。",
    "09:10:00 窗帘状态 CurrentPositionLiftPercent100ths = 0 (完全关闭)，配合窗户的快速开合，符合‘进入 - 操作 - 复原’的入侵模式。"
  ],
  "recommended_actions": [
    "立即通知住户家中可能有人闯入，建议其回家后立即检查门窗锁具及室内情况。",
    "联系物业或安保人员前往现场核实，特别是检查客厅窗户是否有强行开启的痕迹。",

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",

  ],
  "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。

    "对比其他传感器：同一时间段内，客厅、餐厅等其他区域的 occupancy 传感器也有波动，但玄关作为入户通道，其持续的高频“有人”信号若无法被其他设备佐证（如门磁未触发开锁），极大概率是传感器自身故障（Stuck-on）或误报。",

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": [
    "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。

## 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",
  "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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "actuator_stuck",
  "threat_description": "灯的 OnOff 与 Level 矛盾",
  "reasoning": [
    "推理步骤1: 同一时刻 OnOff=False 但亮度非零",
    "推理步骤2: 矛盾状态持续而非瞬时",
    "推理步骤3: 更像执行/上报故障"
  ],
  "key_evidence": [
    "同一时刻 OnOff=False 但亮度非零",
    "矛盾状态持续而非瞬时",
    "更像执行/上报故障"
  ],
  "recommended_actions": [
    "判断为灯具状态机异常，建议检查执行器或状态同步。"
  ]
}

    "温度数据合理性分析：日志中的温度值（如 2471, 2357）符合 Matter 协议中摄氏度乘以 10 的编码标准，换算后分别为 24.71°C 和 23.57°C，处于夏季室内正常舒适范围，无传感器漂移或故障迹象。",

    "设备状态联动正常：厨房洗碗机在 18:42 启动，随后厨房温度传感器短暂返回 None（可能因设备遮挡或重启），但在 18:50 后恢复正常读数；所有门窗接触传感器、烟雾报警器等关键安防设备在日志中未触发异常报警事件。"
