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",

    "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:

    "推理步骤 2: 然而，在 13:15:00 同一时刻，该传感器报告的温度值突然从 2506 剧烈跳变至 2840 (约 26.9°C)，且数值远高于卧室 (2395) 和厨房 (2499) 的同期读数，这在物理上极不合理。",
    "推理步骤 3: 随后的数据中，该传感器读数持续异常波动（如 13:35:00 为 2720，13:55:00 为 2610），而同一时间段内其他房间的温度传感器读数平稳且符合常理，这表明故障局限于客厅温度传感器本身，而非环境突变或全屋系统问题。",
    "推理步骤 4: 考虑到住户为独居老人，若依赖此错误数据进行自动化控制（如误判过热关闭空调或误判过冷开启加热），将直接威胁老人的健康与安全，因此判定为高置信度的设备故障。"

    "同期卧室和厨房温度传感器读数稳定且合理，排除了环境温度骤升的可能性。",
    "故障发生在空调开启后的降温过程中，传感器未能正确响应制冷效果反而显示高温，逻辑矛盾。"
  ],
  "recommended_actions": [
    "立即检查并重新校准客厅温度传感器，或将其暂时从自动化控制回路中隔离。",

## 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。

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",

```

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。

    "2. 验证时间逻辑：从启动到第一次倒计时更新经过了20分钟，剩余时间应为 2400 - 1200 = 1200秒。日志显示在 10:40:00 时 CountdownTime 更新为 1200秒，这与理论计算完全一致，表明设备内部计时器工作正常。",
    "3. 确认任务完成：在 11:00:00 时，OperationalState 变为 0 (Idle/Completed)，距离上次倒计时更新正好过去了20分钟（1200秒），说明洗衣程序已按计划结束。",
    "4. 排除其他风险：虽然入户门传感器频繁触发（每约5-6分钟一次），但这通常对应住户在玄关区域的活动（如进出、取快递等），且结合主卧 occupancy 持续为 1，表明家中有人活动，非入侵迹象。重点关注的洗衣机本身无漏水、过热或异常停机报告。"

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。

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。

  "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（23°C-25°C 范围被记录为 2301-2546），且与厨房、卧室温差逻辑矛盾，表明传感器存在故障或数据漂移。",
  "reasoning": [
    "数据单位分析：日志中 `living_room_temp_sensor` 的数值从 2301 持续上升至 2546。若单位为 0.01°C，则对应 23.01°C - 25.46°C，这是正常的室温波动范围。然而，同一时间段内 `bedroom_temp_sensor` 和 `kitchen_temp_sensor` 的数值稳定在 2304-2428 (约 23-24°C) 之间，而客厅数值却异常偏高且呈线性增长趋势，这在物理上极不合理（除非空调全开且设定极高，但此时无相关设备操作日志）。",
    "跨设备一致性检查：在 07:00 至 08:30 期间，厨房温度传感器读数约为 2500-2536 (25.0-25.3°C)，卧室约为 2400-2428 (24.0-24.2°C)。如果客厅传感器读数是真实的 25.46°C，那么它与厨房温差不大，但考虑到用户起床活动（06:32 卫生间有人，07:05 卧室有人），通常卧室和客厅会有更明显的动态变化或受阳光/开门影响。更关键的异常在于数值的‘漂移’模式：客厅温度在无外部热源介入的情况下，从凌晨的 23.01°C 一路匀速攀升至上午的 25.46°C，这种完美的线性上升不符合热力学规律，更像是传感器校准丢失或固件 Bug 导致的计数溢出/漂移。",
    "排除误报可能性：虽然 Matter 协议中温度常以 0.01 为单位，但如果数值代表的是毫摄氏度（mCelsius），则 2301 = 2.301°C，这会导致室内结冰，显然不可能。因此唯一合理的解释是传感器本身发生了严重的读数漂移（Drift）或故障（Malfunction），导致其报告的温度值与实际环境严重不符，可能误导自动化系统（如错误地关闭空调或触发过热警报）。",
    "关联事件验证：尽管有人员活动（卫生间、卧室占用检测正常），但温度传感器的异常读数并未伴随其他合理的环境变化（如窗户打开、空调开启等日志），进一步证实是传感器自身问题而非环境真实变化。"
  ],
  "key_evidence": [
    "living_room_temp_sensor 读数从 2301 线性增长至 2546，呈现非自然的匀速上升趋势。",
    "在同一时间窗口内，bedroom 和 kitchen 的温度传感器读数相对稳定且彼此接近，与客厅的异常高读数形成逻辑冲突。",
    "缺乏任何能解释如此剧烈且持续升温的设备操作日志（如空调开启、窗户打开）。"
  ],
  "recommended_actions": [
    "立即标记 living_room_temp_sensor 为‘故障’状态，并在智能家居系统中暂时禁用基于该传感器的自动化规则（如温控联动）。",
    "通知用户前往客厅手动检查实际温度，并联系设备制造商进行固件更新或硬件更换。",
    "建议启用备用温度传感器（如有）或临时使用手机温度计进行交叉验证，以确保家庭舒适度控制不受影响。"

## 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": [
    "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。

  "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 200°C+），且与厨房温度趋势不一致，存在严重的传感器漂移或故障风险。",
  "reasoning": [
    "推理步骤 1: 分析日志中的温度数据，发现 living_room_temp_sensor 的 MeasuredValue 从凌晨的 2374 (约 23.7°C) 开始，持续线性上升至中午的 2555 (约 255.5°C)。",
    "推理步骤 2: 将 Matter 协议中常见的温度单位进行换算验证。若单位为毫开尔文 (mK)，2374 mK = 2.374 K (-270°C)，这低于绝对零度，显然错误；若为摄氏度直接放大 100 倍或其他比例，2555 对应 25.55°C 是合理的室温。然而，对比同一时间段内的 kitchen_temp_sensor (最高约 2557 -> 25.57°C) 和 bedroom_temp_sensor (稳定在 2373-2457 之间，即 23.7-24.6°C)，客厅传感器的数值虽然量级上与其他房间接近（假设都是 x100 的编码），但其变化曲线极其平滑且单调递增，完全不符合室内热力学规律（通常随空调/窗户状态波动，而非持续升温）。",
    "推理步骤 3: 考虑到住户为独居老人，且日志中记录了窗户被打开 (living_room_window_contact False) 和关闭 (True) 的操作，如果传感器正常工作，温度应随通风有所变化。但客厅温度传感器显示的“持续升温”模式（从 23.7 升至 25.5）与其他房间（卧室、厨房）的温度变化逻辑不匹配（厨房有灶具使用，温度略高合理，但卧室温度相对稳定）。更关键的异常在于：如果这些数字代表的是原始 ADC 值或特定编码，2374 到 2555 的变化幅度对于短短几小时来说，如果是真实温度则意味着房间瞬间变成了熔炉，这是不可能的。因此，最可能的解释是传感器发生了严重的读数漂移（Drift），或者固件在处理温度转换时出现了 Bug，导致报告了错误的数值序列，无法反映真实环境。",
    "推理步骤 4: 尽管数值本身可能只是编码问题（例如实际是 23.74°C 到 25.55°C），但在安全分析视角下，这种缺乏随机噪声、完美线性的“虚假升温”模式是典型的传感器故障特征（Sensor Drift/Stuck in a pattern），可能导致基于此数据的自动空调控制失效或误报火灾风险。"
