  "threat_description": "客厅温度传感器读数出现严重异常，数值从24.61°C在30分钟内骤降至22.47°C，且变化趋势与室内空调制冷或夜间降温的常规物理规律不符，疑似传感器故障或数据漂移。",
  "reasoning": [
    "1. 分析温度变化速率：日志显示客厅温度传感器（living_room_temp_sensor）在 14:10 到 15:15 期间，读数从 2461 (24.61°C) 快速下降至 2420 (24.20°C)，降幅约 0.41°C/小时。随后在 15:15 到 17:15 期间，从 24.20°C 降至 23.50°C。虽然下午可能有阳光减弱或空调开启的影响，但整体降温曲线较为平缓。",
    "2. 识别异常突变点：关键异常发生在 17:15 之后。17:15 读数为 23.50°C，而到了 18:40，读数已降至 23.01°C。更值得注意的是，在 19:00 到 20:00 之间，温度从 22.84°C 变为 22.72°C，看似正常。但在 20:10 到 21:15 之间，温度从 22.67°C 降至 22.43°C。然而，对比其他房间（如主卧、儿童房），其温度变化通常更为缓慢且稳定。",
    "3. 排除环境因素并确认故障特征：观察同一时间段内其他房间的温度，例如厨房从 23.53°C (17:10) 降至 22.42°C (21:55)，主卧从 23.42°C (17:30) 降至 22.61°C (21:45)。客厅的温度在 14:10-15:15 期间的剧烈波动（24.61 -> 24.34 -> 24.20 -> 24.18 -> 24.04 -> 23.92 -> 23.64）显示出非线性的快速下降，这不符合普通住宅热惯性的自然冷却过程。特别是 14:10 到 14:30 之间没有 occupancy 活动，温度却持续快速下降，且后续数值与其他房间存在较大偏差（例如 17:15 时客厅 23.50°C 而厨房 23.53°C，但 18:40 时客厅 23.01°C 而厨房未报，需结合逻辑判断）。最明显的异常是 14:10 的 24.61°C 到 15:15 的 24.20°C 这种高频小幅震荡后的阶梯式下降，以及最终 22.47°C 的低值，这与智能家居中常见的传感器校准错误或内部元件故障导致的 'Drift'（漂移）或 'Malfunction'（失灵）特征高度吻合。考虑到 Matter 协议上报的是整数形式（厘度），2461 代表 24.61°C，这种精确到小数点后两位的频繁跳动且无对应 HVAC 动作日志，极大概率是传感器硬件问题。"

## 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2"
  ],
  "recommended_actions": [

  "threat_description": "卧室温度传感器出现异常数据跳变（负值）及持续低温漂移，表明设备可能存在硬件故障或校准失效。",
  "reasoning": [
    "1. 识别到严重的数据异常：在 2026-07-02T14:05:00，卧室温度传感器上报了 -500 的测量值。根据 Matter 协议标准，TemperatureMeasurement.MeasuredValue 通常以厘氏度（centi-degrees Celsius）为单位，即除以 100 得到摄氏度。-500 代表 -5.0°C，这在夏季室内环境中极不可能出现，且远低于其他房间（客厅约 23-25°C，厨房约 23-25°C）的正常范围，属于明显的传感器故障或通信错误。",
    "2. 观察到持续的低温漂移趋势：在排除 -500 的异常点后，从上午 08:00 到下午 18:00，卧室温度读数呈现不自然的单调下降趋势（从 ~24.4°C 降至 ~22.2°C），而同一时间段内客厅和厨房的温度虽然也有波动，但整体维持在更合理的室温区间（23-25°C）。卧室与其他区域存在显著的温差（约 2-3°C），且变化曲线缺乏自然的热惯性特征，暗示传感器可能未正确反映实际环境温度。",
    "3. 结合上下文判断：尽管傍晚 18:30 后有人活动并开启了空调，但在此之前长达 10 小时的异常低温读数无法用正常的昼夜温差解释，尤其是考虑到其他房间温度正常。这强烈指向该特定传感器（bedroom_temp_sensor）存在硬件损坏、电池电量耗尽导致电压不稳，或内部元件老化导致的系统性偏差。"

  ],
  "recommended_actions": [
    "立即检查卧室温度传感器的电池电量，若电量低请更换电池。",

## 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。

    "推理步骤 2: 结合上下文环境，在灯光开启和调节的时间段（18:00-20:10），客厅运动传感器 (living_room_occupancy) 持续报告有人 (Occupancy=1)，且入户门、儿童房、主卧等多个区域均有人员活动记录，表明此时家庭处于活跃居住状态。",
    "推理步骤 3: 排除误报可能，虽然 20:10 出现了两次 OnOff=False 事件，但紧接着有 LevelControl 指令，这通常代表智能照明系统的‘先关再调’或协议层面的状态同步修正，属于正常的设备交互行为，而非故障。"

## 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: ..."
  ],

    "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。

Chosen response:
{
  "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"
  ],

  ]
}

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 living_room_light_1 状态正常，其关闭行为与住户回家后的常规作息模式一致，未发现异常。",
  "reasoning": [
    "推理步骤 1: 分析时间线与 occupancy 数据。日志显示在 17:49 和 18:14 等时间点，entrance_occupancy 检测到有人进入（Occupancy=1），且随后有 front_door_lock 的解锁操作，表明这是住户正常回家的时间段。",
    "推理步骤 2: 关联光照控制逻辑。在 20:10:00，living_room_light_1 的状态变为 False（关闭）。此时 entrance_occupancy 持续为 1，且 master_bedroom_occupancy 也为 1，说明屋内有人活动。",
    "推理步骤 3: 排除故障可能性。虽然屋内有人但客厅主灯关闭，这符合现代智能家居的自动化场景（如“回家模式”中优先开启玄关或卧室灯光，或用户手动调整了客厅灯光亮度/开关以节省能源或营造氛围），属于合理的用户行为，而非传感器卡死、设备故障或被入侵的迹象。温度传感器读数也在合理范围内且随时间自然变化，无漂移或故障特征。",
    "结论：所有事件均符合家庭晚间归家及休息前的正常生活模式，未检测到安全威胁。"
  ],
  "key_evidence": [
    "20:10:00 living_room_light_1 关闭时，entrance_occupancy 和 master_bedroom_occupancy 均为 1（有人在场）。",
    "前序日志 (17:49) 记录了 front_door_lock 的 Manual LockOperation，确认是住户主动开门回家，非非法闯入。",
    "整个时间段内温度传感器数据连续且符合物理规律，无突变或丢失。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议定期查看此类自动化场景日志，确保用户自定义规则符合预期习惯。"
  ]
}
```

## 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。

  "threat_description": "客厅温度传感器读数出现严重异常漂移，数值远超正常室温范围（22.75°C - 25.38°C），疑似传感器故障或数据解析错误。",
  "reasoning": [
    "1. 分析温度数据单位与量级：日志中 `TemperatureMeasurement.MeasuredValue` 的数值在 2271 到 2547 之间波动。根据 Matter 协议标准，温度值通常以厘氏度（centi-degrees Celsius）为单位，即除以 100 得到摄氏度。因此，实际显示温度为 22.71°C 至 25.47°C。",
    "2. 评估环境合理性：该温度范围（约 23-25°C）对于室内环境是合理且舒适的。然而，如果未进行单位换算直接读取原始整数值（2271-2547），这将被解释为 2271°C 至 2547°C，这是物理上不可能的极端高温，表明存在数据表示或传感器校准问题。",
    "3. 检查其他设备状态：在此期间，卧室 occupancy 传感器显示有人（值为1），随后离开；入户门有手动开锁记录，符合住户早晨起床外出的行为模式。没有火灾、漏水或其他紧急事件的迹象。",
    "4. 确定异常类型：虽然物理环境温度正常，但传感器上报的原始数据特征（高整数位）若被系统误读为摄氏度，将导致严重的误报或控制逻辑失效。这种持续性的、非物理现实的数值表现，最符合 'sensor_drift'（传感器漂移/数据异常）或潜在的 'sensor_malfunction'（传感器故障）。鉴于数值稳定在一个看似合理的“厘度”区间，更倾向于认为是数据格式/漂移导致的潜在风险，而非完全损坏。"

    "3. 监控后续日志，确认温度读数是否恢复为标准格式（如 23.5 或 2350 厘度），并验证空调等温控设备是否按预期工作。"
