## 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": [
    "推理步骤1: 正常样本是一次性短暂重连；异常样本在短时间内反复抖动。"
  ],
  "key_evidence": [
    "正常样本是一次性短暂重连；异常样本在短时间内反复抖动。"
  ],
  "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": "厨房温度传感器出现严重数据漂移和丢失，读数异常飙升（最高达 2936）且随后中断，无法反映真实环境温度。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kitchen_temp_sensor 在正常范围内波动（约 2540-2550），但在 11:10 至 11:55 期间数值急剧异常上升，从 2542 飙升至 2936，这在物理上是不可能的（远超设备熔点或传感器量程）。",
    "推理步骤 2: 该异常读数发生在卧室有人活动且客厅空调重启后的时间段内，排除了外部极端热源导致的可能性，更符合传感器内部故障或通信干扰导致的乱码。",
    "推理步骤 3: 在 11:56:00，该传感器报告了 None 值，表明设备可能已完全离线、重置或因固件错误停止上报数据，进一步证实了硬件或软件层面的故障，而非环境变化。"
  ],
  "key_evidence": [
    "kitchen_temp_sensor 读数在 11:30 达到 2936 (单位通常为 0.01°C，即 29.36°C 或若单位为 mK 则高达 29360°C，均不合理)",
    "kitchen_temp_sensor 在 11:56:00 返回 None 值，显示数据流中断"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理状态，确认是否被遮挡、损坏或受到强电磁干扰。",
    "尝试重新配对或重启厨房温度传感器以恢复其 Matter 连接。",
    "在修复前，建议人工定期手动测量厨房温度，以防因传感器失效导致火灾风险误判或漏报。"
  ]

## 任务
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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。

    "推理步骤 2: 结合住户背景（独居老人），虽然夜间空调可能关闭，但室内温度通常不会在无人状态下以如此快的速度自然升高超过 1.5°C，且厨房和卧室温度相对平稳（约 22-23°C），排除了全屋普遍升温的可能性。",
    "推理步骤 3: 对比 Matter 协议标准及物理常识，该传感器数值（如 2403 对应约 24°C）看似合理，但在长达 3.5 小时内呈现单调递增且无波动趋势，不符合热力学平衡规律，符合传感器漂移（Drift）或校准失效的特征。若此数据被用于联动逻辑（如自动开窗或报警），将引发严重的安全误报或设备损坏风险。"

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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": "fire_risk",
  "threat_description": "独居老人家中客厅温度在夜间无人状态下持续异常升高，且伴随空调关闭，存在严重的火灾隐患。",
  "reasoning": [
    "1. 环境状态分析：日志显示从 00:30 开始，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的运动传感器均报告 Occupancy = 0，表明整栋房屋处于完全无人状态。",
    "2. 异常模式识别：在无人状态下，客厅温度传感器读数从凌晨 00:10 的约 22.8°C (2284mK) 持续攀升至 04:15 的约 24.2°C (2419mK)，温差超过 1.4°C。更严重的是，厨房温度也同步上升，最高达 23.78°C (2378mK)。",
    "3. 设备行为矛盾：通常夜间无人时，空调应开启以维持舒适温度或节能运行。然而，日志中未见空调控制指令，且温度呈现不受控的上升趋势，这不符合正常热力学规律（除非有外部热源）。",
    "4. 排除误报：虽然 02:10-02:16 期间灯光有短暂开关动作，但这可能是自动感应或误触，不足以解释长达数小时的持续升温。考虑到住户为独居老人，无法及时应对突发火情，此情况风险极高。",
    "5. 结论：在无人员活动、无空调调节的情况下，室内温度持续显著升高，极有可能是由未熄灭的电器、线路短路或燃气泄漏引发的早期火灾征兆。"

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

  "threat_description": "独居老人家中客厅温度在夜间无人状态下持续异常升高，且伴随空调关闭，存在严重的火灾隐患。",
  "reasoning": [
    "1. 环境状态分析：日志显示从 00:30 开始，所有房间（包括客厅、卧室、厨房）的运动传感器均报告 Occupancy = 0，表明整栋房屋处于完全无人状态。",
    "2. 异常模式识别：在无人居住的情况下，客厅温度传感器读数从凌晨 00:10 的 22.68°C (2268mK) 持续单调上升至 04:00 的 24.10°C (2410mK)，并在随后几小时内继续攀升至 23.94°C-24.04°C 区间（注意：Matter 协议中温度常以毫开尔文 mK 为单位，2400mK ≈ 20.85°C + 偏移量，此处需结合上下文判断趋势。若原始数据为摄氏度直接乘以 10 或类似缩放，则 2268 代表 22.68°C。假设单位为 mK，2268mK=19.53°C, 2410mK=20.95°C。即使按摄氏度理解，温差也显著）。更关键的证据是温度呈现**持续单向上升**趋势，而非随环境温度自然波动。",
    "3. 设备行为矛盾：虽然日志中未明确显示空调关闭事件，但通常夜间无人时空调应处于节能或关闭状态。然而，如果空调仍在运行且设定温度高于当前室温，或者空调故障导致制热/制冷失效，会导致室内温度异常。考虑到独居老人的背景，最可能的情况是：**空调被误设为加热模式且无人干预，或者空调系统故障导致热量积聚**。",
    "4. 风险推导：对于独居老人，夜间长时间无人看管且室内温度持续异常升高，极易引发火灾（如电器过热、线路老化加速）或导致老人因高温醒来后无法及时应对。这种‘无人 + 持续升温’的组合是典型的火险前兆。",
    "5. 排除其他因素：光照变化符合昼夜规律（凌晨关灯，白天开灯），无入侵迹象（门窗传感器未触发），无漏水迹象。核心问题在于热环境的失控。"
  ],
  "key_evidence": [
    "00:30 - 04:00 期间所有房间运动传感器连续报告 Occupancy = 0（无人状态）。",
    "living_room_temp_sensor 读数在无人状态下从 2268 持续上升至 2410（约 1.4 度以上的温升），且趋势未出现回落。",
    "该时间段内无任何人员活动记录，排除了人为热源（如做饭、取暖器使用）的可能性。"
  ],
  "recommended_actions": [
    "立即远程检查并重置客厅空调设置，确保其处于关闭或自动模式，避免持续加热。",
    "联系住户或其紧急联系人，确认老人安全及家中实际状况。",
    "建议安装或启用智能温控器的‘离家模式’自动逻辑，当检测到全屋无人超过一定时间（如 2 小时）时自动关闭非必要加热设备。",

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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严重偏离物理现实，显示异常高温（约 230°C-240°C），而卧室和厨房温度正常，表明传感器故障或漂移。",
  "reasoning": [
    "数据合理性分析：日志中客厅温度传感器 (living_room_temp_sensor) 的 MeasuredValue 在 2279 到 2414 之间。Matter 协议通常将摄氏度乘以 10 进行传输，因此实际温度为 227.9°C 至 241.4°C。对于室内环境而言，这是不可能的物理状态。",
    "交叉验证失败：在同一时间段内，卧室 (bedroom_temp_sensor) 和厨房 (kitchen_temp_sensor) 的温度读数分别为 2198-2274 (约 22-23°C) 和 2306-2367 (约 23-23.7°C)。这些数值符合夏季夜间/清晨的正常室温范围，且三个房间之间的温差合理（厨房略高可能因电器散热）。",
    "设备行为关联：尽管温度传感器报告了极端的“高温”，但客厅空调 (air_conditioner) 并未在日志中出现开启制冷模式以应对这种极端高温的记录，且住户（独居老人）在凌晨时段未表现出任何因过热导致的异常活动（如频繁开关灯、移动等），直到天亮后灯光才正常开启。这表明高温是虚假读数而非真实热事件。",
    "结论：单一传感器持续输出超出物理极限的数值，而其他同类型传感器工作正常，确认为传感器漂移 (sensor_drift) 或硬件故障。"
