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",

    "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": [

  ],

  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"

Rejected response:

    "推理步骤 1: 日志显示在 2026-07-25T13:00:00 时，客厅空调 (living_room_ac) 被开启 (OnOff.OnOff = True)。",
    "推理步骤 2: 在空调开启前 (13:14:03)，客厅温度传感器报告值为 28.4°C (2840/100)，随后在 13:20:00 降至 24.87°C，这符合空调制冷的正常物理规律。",
    "推理步骤 3: 然而，在 13:35:00 和 13:55:00，该传感器再次报告异常高温值 (27.2°C 和 26.1°C)，且数值波动剧烈（如 13:55:00 两次上报分别为 24.82°C 和 26.10°C），这与空调持续运行导致室温应逐渐下降的趋势完全相反。",
    "推理步骤 4: 考虑到住户为独居老人，若真实环境温度如此之高且空调无法降温，将构成严重的健康威胁；但结合其他房间（卧室、厨房）温度读数稳定且合理（约 22-24°C），可推断客厅温度传感器本身存在硬件故障、校准漂移或通信干扰，而非真实环境过热。"

    "2026-07-25T13:55:00 living_room_temp_sensor MeasuredValue 先报 2482 后报 2610 (同一时刻数据剧烈跳变)"
  ],
  "recommended_actions": [
    "立即检查并重新校准客厅温度传感器，或将其从 Matter 网络中移除以防误报触发火灾报警。",
    "安排技术人员上门检修该传感器硬件，确认是否存在元件损坏或供电不稳问题。",

## 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:

  "threat_description": "客厅温度传感器在下午 17:00 出现严重数据跳变，从约 23°C 瞬间跳升至 25.2°C，随后卧室传感器也出现异常高值，且厨房传感器在 16:59 报告无数据，表明存在设备故障或通信中断。",
  "reasoning": [

    "推理步骤 3: 同时刻卧室温度传感器 (bedroom_temp_sensor) 也报告了异常高的数值 25.80°C (2580 mK)，随后迅速回落至正常范围 (22.49°C)。多个传感器在同一时间点出现非自然的数值跳跃或丢失，极大概率是传感器硬件故障、固件崩溃或网络重连导致的瞬态错误，而非真实的环境变化。",

System:
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。

    "1.  occupancy_sensor (运动传感器) 状态分析：日志显示客厅、次卧、玄关等区域的 OccupancySensing.Occupancy 持续为 0。结合时间戳（14:00 - 21:05），这符合家庭成员外出或处于非活动区域的状态，属于正常的空闲模式，并非传感器故障（若故障通常表现为固定值但伴随其他逻辑冲突，此处无冲突）。",
    "2.  temperature_sensor (温度传感器) 数据分析：客厅温度从 14:10 的 24.74°C 逐渐下降至 21:05 的 22.59°C。这种缓慢且平滑的温度变化趋势符合夏季傍晚自然降温或空调运行后的热平衡过程，数据波动在合理范围内，未发现跳变、停滞或极端值，排除 sensor_stuck 或 sensor_drift。",
    "3.  living_room_light_1 (主灯) 行为分析：在 20:10 开启并调光至 Level 180，随后在 20:18 调暗至 Level 30。这一系列操作发生在晚间时段，且此时所有运动传感器均为 0（无人）。虽然有人时开灯更常见，但在智能家居场景中，用户可能通过手机 App 远程控制灯光，或者设置了定时/自动化场景（如‘离家模式’下的氛围灯）。由于没有伴随入侵迹象（门锁未异常开启、窗户未打开）或其他危险信号，此行为判定为正常的远程操控或预设场景执行，而非异常入侵。"
  ],
  "key_evidence": [
    "OccupancySensing.Occupancy 在 14:00-21:05 期间持续为 0，表明房屋处于无人或低活动状态。",

    "living_room_light_1 在 20:10 开启并在 20:18 调暗，符合晚间远程控制或自动化场景特征，且无其他入侵证据。"

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。

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。

    "推理步骤 1: 分析温度数据趋势。从凌晨 03:10 到上午 09:50，客厅 (living_room) 温度从约 23.7°C (2368/100) 持续上升至 25.6°C (2556/100)，厨房 (kitchen) 温度也从 24.8°C 上升至 25.6°C。虽然绝对值看似不高，但在无人员活动的情况下，这种持续且显著的升温速率（尤其是厨房区域）不符合自然散热规律，暗示有热源产生。",
    "推理步骤 2: 结合 occupancy 状态进行交叉验证。日志显示在温度急剧上升期间（07:15 - 09:50），客厅运动传感器 (living_room_occupancy) 多次报告为 0（无人）。这意味着高温并非由住户活动引起，而是环境本身的问题。",
    "推理步骤 3: 关联窗户状态与热力学逻辑。09:10 时客厅窗户被打开 (CurrentPositionLiftPercent100ths = 5000)，随后接触传感器变为 False（开启）。通常开窗会加速散热导致降温，但在此之后，厨房温度仍在高位徘徊甚至微升，且客厅温度并未出现预期的快速下降，这表明内部可能存在持续的热源（如灶具未关、电器故障或线路过热），或者窗户开启是试图缓解但未成功掩盖了核心问题。考虑到厨房温度长期维持在 25.5°C+ 且无人看管，极有可能是灶具 (cook_surface) 处于意外开启状态或发生了电气故障。",
    "推理步骤 4: 排除其他因素。卧室有人活动但温度正常波动，排除了全屋空调失效的可能性；入户门锁操作发生在 07:33，属于正常离家流程，非入侵迹象。综合来看，最合理的解释是厨房区域存在未察觉的火灾隐患。"

## 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",

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。

## 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": "洗衣机运行状态正常，符合典型的家庭洗衣流程（启动-倒计时结束-停止），未检测到安全威胁或设备故障。",
  "reasoning": [
    "1. 分析目标设备 'balcony_laundry_washer' 的状态变化：在 10:00:00 时，OperationalState 变为 1 (Running/Active)，表明洗衣机开始工作。",
    "2. 观察倒计时逻辑：10:20:00 时 CountdownTime 为 2400秒 (40分钟)，10:40:00 时 CountdownTime 为 1200秒 (20分钟)。这表明设备正在按预期进行倒计时，且时间流逝与倒计时减少量一致（20分钟内减少了20分钟的剩余时间），证明设备内部计时器工作正常。",
    "3. 确认任务完成：11:00:00 时，OperationalState 变为 0 (Idle/Stopped)，此时距离启动已过去60分钟。虽然中间显示的剩余时间是20分钟，但考虑到洗衣机可能包含脱水、烘干等阶段，或者日志采样间隔导致的显示差异，最终状态归零表明一个完整的洗涤周期已结束。",
    "4. 结合环境上下文：在此期间（10:00-11:00），家中其他区域（如主卧、儿童房）有人员活动迹象（Occupancy=1），且温度传感器读数在合理范围内波动，没有火灾、漏水或入侵的迹象。"
