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",

    "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。

  "confidence": "high",

  "threat_description": "客厅温度传感器在14:05报告了-500的异常数值，随后读数迅速恢复并呈现符合环境规律的下降趋势，表明该次读数极大概率为传感器硬件故障或通信错误导致的无效数据。",
  "reasoning": [
    "数据分析：日志显示客厅温度传感器（living_room_temp_sensor）在14:05时报告的测量值为 -500。",
    "合理性检查：根据Matter协议及常规智能家居传感器标准，室内环境温度通常在-20°C至60°C之间。-500显然超出了物理合理范围，属于典型的无效数据或溢出值（如未初始化的默认值、通信丢包后的占位符或ADC转换错误）。",
    "趋势对比：在-500出现之前（14:00），读数为2430（即24.30°C）；在-500出现之后（14:10），读数恢复为2440（即24.40°C）。且从08:00到16:50的整体趋势中，其他房间（主卧、儿童房、厨房）的温度变化曲线平滑且相互关联（均在23-25°C区间波动），唯独客厅在此刻出现极端离群点。",
    "排除法：由于后续读数立即恢复正常且符合整体室温下降的趋势（从早晨的~25°C降至下午的~23.6°C），可以排除是真实的环境突变（如空调故障或窗户打开导致瞬间极寒/极热），因此判定为传感器本身的故障或单次传输错误。"

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",

    "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。

  "confidence": "medium",
  "threat_type": "sensor_stuck",

  "reasoning": [

    "推理步骤 3: 尽管有人员活动记录（entrance_occupancy, dining_room_occupancy），但厨房温度并未随人员离开而下降，反而呈现持续上升趋势，且未触发烟雾报警器（smoke_co_alarm）报告，表明可能存在设备故障或燃气泄漏导致的过热隐患，构成高置信度的火灾风险。"

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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器出现异常读数跳变及数据丢失，疑似硬件故障或通信干扰。",
  "reasoning": [
    "1. 分析厨房温度传感器日志：在12:05时读数为2556 (约25.5°C)，随后在12:25骤升至2909 (约29.1°C)，紧接着在12:29变为None（无数据/断连），12:30又恢复为2928 (约29.3°C)。这种剧烈的数值波动伴随数据中断是典型的传感器故障特征。",
    "2. 排除烹饪影响：虽然12:10灶具开启，但通常灶具产生的热量会使温度缓慢上升，不会导致传感器瞬间“失联”后读数反而更高且不稳定。此外，其他房间（客厅、卧室）温度保持相对稳定（24-25°C左右），说明并非全屋环境突变。",
    "3. 对比其他设备：同一时间段内，客厅和卧室的温度传感器读数变化平缓，符合正常热力学规律，进一步证实问题仅局限于厨房温度传感器本身或其与网关的通信链路。"

  ],
  "recommended_actions": [
    "检查厨房温度传感器的电池电量或供电状态，尝试更换电池或重新上电。",
    "若问题持续，建议重置该传感器或联系厂家进行硬件检测，以排除传感器内部元件损坏的可能性。"
  ]
}
```

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "这些变化仍可视为正常波动。",
  "reasoning": [
    "推理步骤1: 没有看到必须报警的直接证据。"

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。

    "2. 观察后续数据恢复情况：在故障发生后的 5 分钟（14:10:00），该传感器读数恢复至 2440（24.40°C），这与同一时间段内客厅（24.67°C）和厨房（24.68°C）的温度读数趋势一致，说明环境温度并未发生剧烈变化，进一步证实了之前的 -500 读数是设备端的异常而非真实环境变化。",

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。

## 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",

    "2. 识别异常数据点：在[2026-08-25T14:05:00]时刻，living_room_temp_sensor报告了MeasuredValue = -500。转换为摄氏度为-5.00°C。考虑到此前一刻（14:00）读数为24.30°C，且同一时间段内其他房间（如厨房、儿童房）温度均在23-24°C左右，-5°C的骤降极不符合物理规律，属于典型的传感器故障或数据包损坏。",
    "3. 观察后续行为：在异常读数后，传感器在14:10恢复至24.40°C，随后读数逐渐下降至23.73°C（16:50），这与室外气温降低或空调运行的趋势一致，说明传感器并未完全失效，而是出现了间歇性的严重错误读数。这种非线性的、超出合理范围的跳变是典型的传感器 malfunction 特征。"

## 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",

}
```

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。
