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": "检测到客厅和厨房温度持续异常升高，且伴随窗户开启但室内无人，存在严重的火灾风险或设备过热隐患。",
  "reasoning": [
    "推理步骤 1: 分析温度数据趋势。从 03:10 到 11:10，客厅温度传感器读数从 23.65°C (2365/100) 持续上升至 25.41°C (2541/100)，其中在 09:30 达到峰值 25.59°C。虽然绝对值看似不高，但需结合上下文判断。更关键的是，厨房温度在同一时间段内也呈现同步上升趋势，从 24.79°C 升至 25.57°C。",
    "推理步骤 2: 关联 occupancy（占用）状态。日志显示，在温度显著上升的整个时段（03:10 - 11:10），living_room_occupancy 和 kitchen_temp_sensor 附近的区域均报告 Occupancy = 0（无人）。这意味着房间处于无人看管状态，而温度却在持续攀升，这不符合正常自然降温或恒温逻辑，暗示有热源持续工作。",
    "推理步骤 3: 检查安全设备与物理环境。尽管温度升高，但 living_room_window_contact 在 09:10 变为 False（打开），随后在 09:20 又变为 True（关闭）。如果是因为开窗散热导致温度变化，通常会有明显的通风气流特征，且不会在关窗后温度继续维持高位。更重要的是，厨房烟雾报警器 (smoke_co_alarm) 在此期间的日志中完全缺失，而在高温且无人的情况下，若存在电气故障或燃气泄漏引发小火苗，烟雾报警器应已触发报警。这种‘高温 + 无人 + 无烟雾报警’的组合是典型的传感器失效或早期火灾被掩盖的迹象。此外，卧室灯在 06:22 开启，但随后所有房间 occupancy 均为 0，说明住户并未在室内活动，排除了人为开空调取暖的可能性。",
    "推理步骤 4: 综合判断。在无人员活动的情况下，厨房和客厅温度持续非自然上升，且关键的烟雾探测设备未响应，极有可能是厨房灶具 (cook_surface) 或其他电器发生过热、短路等故障，或者烟雾传感器本身发生故障未能检测危险。考虑到 Matter 协议下设备报告的连续性，这种长时间的高温累积是一个高危信号。"

  "key_evidence": [
    "living_room_temp_sensor 和 kitchen_temp_sensor 在无人 (Occupancy=0) 的情况下持续升温，最高达 25.59°C 和 25.57°C。",
    "在温度异常升高的整个过程中，厨房烟雾报警器 (smoke_co_alarm) 没有任何事件记录，存在安全隐患。",
    "住户行为模式异常：卧室灯开启后，所有房间长期无人，排除了正常生活场景下的温度波动。"
  ],
  "recommended_actions": [
    "立即远程通知住户家中存在高温异常，并建议其尽快回家检查厨房及客厅情况。",

## 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",

  "reasoning": [
    "推理步骤 1: 在 2026-08-20T13:00:00，系统检测到客厅空调 (living_room_ac) 被开启 (OnOff.OnOff = True)，此时客厅温度传感器读数约为 25.0°C (2501 mK)，符合常理。",
    "推理步骤 2: 随后在 2026-08-20T13:15:00，即空调开启仅 15 分钟后，温度传感器读数突然飙升至 28.4°C (2840 mK)。考虑到空调正在运行且其他房间温度正常下降或持平，这种瞬间剧烈升温不符合物理规律（除非是极端的局部热源，但无相关日志支持）。",
    "推理步骤 3: 更关键的异常发生在 2026-08-20T13:35:00，当空调已运行一段时间，理论上室内应开始降温时，温度传感器读数再次异常跳变至 27.2°C (2720 mK)，而同一时刻厨房、次卧、主卧的温度均在 24.8°C - 24.9°C 之间稳步下降。这表明传感器数据与其他环境数据严重背离，存在明显的漂移或故障。",
    "推理步骤 4: 尽管后续数据有所回落，但在空调运行期间出现的多次非单调、大幅度的数值波动（如从 24.8 跳到 28.4 再跳回 24.8），强烈暗示传感器硬件故障、校准失效或通信干扰，属于典型的 sensor_malfunction。"

## 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": 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: 正常样本窗户/窗帘状态变化一致；异常样本存在重复矛盾读数。"
  ],
  "key_evidence": [
    "正常样本窗户/窗帘状态变化一致；异常样本存在重复矛盾读数。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房温度持续异常升高且伴随窗户关闭，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析厨房温度传感器数据，发现从 06:10 (2473) 开始，温度呈线性快速上升趋势，至 08:20 达到峰值 2545，并在后续时段维持在 2530-2560 的高位区间。",
    "推理步骤 2: 将温度值转换为摄氏度（Matter 协议通常以 0.1°C 为单位），计算得出厨房温度已超过 25°C，且上升速率极快（约 1.5°C/分钟），远超正常环境温度波动范围，表明有强热源持续工作。",
    "推理步骤 3: 结合上下文，虽然日志中未直接显示灶具开启事件，但如此剧烈的升温通常由灶具、烤箱或烘干机引起。关键风险点在于：在温度飙升期间（06:10 - 09:20），客厅窗户处于关闭状态（09:10 前为 False，09:20 才变为 True），导致热量无法自然散发，极易引发过热甚至火灾。此外，卧室和客厅温度也随时间推移缓慢上升，符合全屋积热特征。",
    "推理步骤 4: 尽管入户门锁在 07:20 被解锁并有人离开（门接触传感器变真），但这发生在高温开始后的初期，不能排除内部设备无人看管继续加热的情况。"
  ],
  "key_evidence": [
    "厨房温度在 2 小时内从 ~24.7°C 飙升至 ~25.5°C，且后期维持高位不降。",
    "在最高温出现时段（07:20-09:10），客厅窗户传感器显示为关闭状态（False）。",
    "温度变化曲线呈现典型的加热设备持续运行特征，而非环境自然波动。"
  ],
  "recommended_actions": [
    "立即远程通知住户家中厨房可能存在火灾隐患，要求检查灶具是否忘记关闭。",
    "若系统具备联动能力，尝试自动打开客厅及厨房窗户以增加通风散热。",
    "建议用户手动前往厨房确认烟雾报警器状态，并检查是否有焦糊味。"

## 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. 检查关联环境数据：洗衣机运行期间（10:00-11:00），厨房温度传感器读数在 2546-2553 之间波动，属于正常的室内环境温度范围，未出现因漏水或短路导致的异常高温。同时，厨房漏水传感器、烟雾报警器在日志片段中无报警记录。",
    "3. 检查住户活动模式：洗衣机运行时，玄关运动传感器多次触发（10:40, 11:00），表明有人在家活动，排除了设备无人看管导致潜在风险（如漏水未被及时发现）的情况，且整体行为符合日常家务习惯。"

## 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: ...",
    "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。

Chosen response:
{
  "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: 正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "key_evidence": [
    "正常样本两房间仍保持接近；异常样本差值突然扩大且只有一侧偏移。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在 17:28 报告了无效值 (None)，随后立即恢复，表明设备存在通信故障或硬件异常。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，厨房温度传感器 (kitchen_temp_sensor) 在 17:25 正常报告 2456 mK (约 24.5°C)，但在 17:28 突然报告 MeasuredValue = None。",
    "推理步骤 2: 该设备在 10 分钟后 (17:30) 又恢复了正常读数 (2343 mK)。这种‘有值 -> 无值 -> 有值’的瞬时中断模式是典型的传感器通信丢包、电源波动或内部固件崩溃特征，而非环境温度的真实突变。",
    "推理步骤 3: 考虑到住户为独居老人，且厨房涉及用火安全（灶具），关键安全传感器的间歇性失效属于高风险事件，可能导致火灾报警延迟或无法监测过热情况，因此判定为 sensor_malfunction。"
