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。

    "1. 分析重点设备日志：在 09:10:00 到 09:12:00 之间，客厅窗户传感器 `living_room_window_contact` 的状态发生了剧烈变化。",
    "2. 具体异常模式：09:10:00 时状态为 True (关闭/闭合)，仅2分钟后即 09:12:00 变为 False (打开/断开)。紧接着在 09:15:00，窗帘执行器 `living_room_window` 被操作至位置 0 (通常代表完全关闭)，但此时窗户传感器并未立即反馈为 True，或者在后续日志中未看到明确的稳定闭合确认（虽然日志截断，但之前的快速跳变已构成疑点）。",
    "3. 排除正常行为：用户不太可能在2分钟内反复开关窗户两次（开-关-开），且没有伴随其他明显的交互行为（如灯光开启、人员移动等）来佐证这一高频操作。这种短时间的状态不稳定（Flapping）是典型的传感器硬件故障、磁铁脱落或通信干扰特征。",
    "4. 结合上下文：同一时间段内温度传感器读数平稳上升，无火灾或极端环境迹象；门锁操作发生在早上7点多，与本次异常无关。因此，问题集中在窗户传感器本身的稳定性上。"

## 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",
    "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。

  "reasoning": [

    "推理步骤 2: 在 08:40 之前，厨房温度已从清晨的约 24.8°C (2480 mK) 攀升至 25.4°C (2543 mK)，并在后续时段维持在 25.3°C - 25.5°C 的高位区间，远超正常室温波动范围。",
    "推理步骤 3: 尽管日志中显示灶具在 11:31 关闭，但在关闭前长达数小时的持续高温表明可能存在未察觉的明火、燃气泄漏燃烧或设备故障导致的过热，对于独居老人而言这是严重的安全隐患。"
  ],
  "key_evidence": [

    "06:24 至 08:40 期间，kitchen_temp_sensor 数值从 2480 持续上升至 2543，呈现明显的升温趋势。",
    "整个上午（09:00-12:06）厨房温度始终维持在 2530-2558 的高位，未出现回落至正常水平的迹象。"

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",

  ],
  "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": "多个房间的温度传感器读数出现异常升高，且数值格式疑似存在单位换算错误或传感器故障（如将摄氏度误报为华氏度或内部计数值未转换），导致系统无法正确反映真实室温。",
  "reasoning": [
    "1. 分析温度数值范围：日志中所有温度传感器的 `MeasuredValue` 均在 2268 到 2559 之间。在 Matter 协议标准中，`TemperatureMeasurement` Cluster 的 `MeasuredValue` 通常以厘度（centi-degrees Celsius）为单位，即除以 100 得到摄氏度。若按此标准，2270 代表 22.7°C，这是非常正常的室内温度。然而，如果该设备固件实现有误，直接上报了华氏度（Fahrenheit）或未经缩放的原始 ADC 值，则 22-25°C 的范围完全不合理（相当于 70-77°F，虽然数值上接近，但整数部分差异巨大；或者如果是原始值，2200+ 对于任何常见温度单位都过高）。",
    "2. 观察变化趋势与逻辑矛盾：从凌晨 00:00 到上午 12:35，温度读数呈现持续、单调上升的趋势（从 ~2270 升至 ~2550）。在夜间至清晨时段，室外气温通常较低或保持平稳，室内温度不应在没有加热源开启的情况下持续线性上升超过 20-30 个单位。这种违背热力学常识的持续上升趋势表明传感器可能存在校准漂移、固件 Bug 或数据上报格式错误。",
    "3. 结合 occupancy 状态排除人为干扰：尽管主卧和卫生间有人员活动（Occupancy=1），但这些活动并未伴随空调或加热设备的明显控制日志（日志中主要展示的是传感器读数和简单的开关灯/门锁状态，未见 HVAC 调节日志）。即使考虑人体散热，如此大范围、全房间、长时间的温度同步异常升高更指向传感器本身的系统性问题，而非局部热源。"

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",

  ],
  "recommended_actions": [

}
```

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。

  "reasoning": [
    "1. 分析温度数据趋势：在13:00客厅空调开启后，环境温度应逐渐下降或保持稳定。然而，living_room_temp_sensor在13:15、13:35和13:55分别上报了2920 (29.2°C)、2940 (29.4°C) 和 2960 (29.6°C) 的数值。",
    "2. 对比其他设备状态：同一时间段内，厨房温度传感器显示正常降温趋势（从2502降至2472），卧室温度也处于正常范围（约23-24°C）。这表明室内整体并未达到近30°C的高温，排除了全屋高温的可能性。",
    "3. 结合空调行为判断：虽然空调在13:00开启，但随后的高温读数并未导致空调关闭或持续高负荷运行以对抗极端热源（日志中未显示空调频繁启停或功率异常，仅显示OnOff=True）。且这些高温读数间隔出现（中间夹杂正常读数如2501, 2486），呈现典型的传感器信号干扰或硬件故障特征（Stuck/Malfunction），而非真实的环境变化。"

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

  "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。

    "1. 分析温度数据趋势：在2026-08-20的大部分时间里（07:05至13:15），客厅温度传感器读数在2500-2550之间波动（对应约25.0°C-25.5°C），与其他房间（厨房、卧室）的温度趋势一致，符合夏季室内正常升温规律。",
    "2. 识别异常点：在13:15、13:35和13:55三个时间点，客厅温度传感器突然上报了2920、2940、2960的数值（对应约29.2°C-29.6°C）。",
    "3. 排除环境因素：尽管空调在13:00开启，但随后其他所有房间的温度传感器均显示温度持续下降（从~25°C降至~23°C以下），表明整体环境温度正在降低。如果客厅真的升至近30°C，这与其他区域的热力学状态严重不符，且没有伴随门窗打开等导致局部高温的事件记录。",
    "4. 确认故障模式：异常读数呈现“尖峰”状，随后立即恢复正常值（如13:20回到2497），这种非物理性的瞬时跳变是典型的传感器电子故障、校准漂移或通信数据包损坏的特征，而非真实的环境变化。"

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_type": "sensor_malfunction",
  "threat_description": "客厅温度传感器读数异常偏高且数值格式疑似错误（单位或精度问题），导致系统记录的温度值远超正常室温范围。",
  "reasoning": [
    "1. 分析温度数据量级：日志中 `living_room_temp_sensor` 的 `MeasuredValue` 在 2375 到 2559 之间波动。根据 Matter 协议标准，TemperatureMeasurement Cluster 的 MeasuredValue 通常以厘氏度（centi-degrees Celsius）为单位，即实际温度 = 测量值 / 100。若按此标准，2375 代表 23.75°C，这是非常正常的室内温度。",
    "2. 识别潜在异常模式：然而，题目重点标记了 `living_room_window` 和 `living_room_window_contact`，暗示需关注环境变化对设备的影响。观察发现，当窗户状态发生变化时（如 09:10 打开，09:12 关闭），温度读数并未出现符合物理规律的剧烈波动（如开窗后迅速降温）。相反，温度读数呈现缓慢、线性的上升趋势（从早晨的 ~24°C 升至上午的 ~25.5°C），这符合夏季清晨自然升温的物理规律。",
    "3. 关键矛盾点与误报排除：虽然 2375-2559 的数值本身作为“厘氏度”是合理的，但结合任务类型 SQ1 和重点关注窗户传感器的设定，我们需要检查是否有其他解释。注意看 06:34 卧室窗帘打开，随后卧室温度稳定在 23-24°C 左右。而客厅温度持续上升。如果假设这些数值不是厘氏度而是直接摄氏度（即 2375°C），那显然是传感器故障。但在智能家居语境下，更常见的“异常”是指**传感器漂移**或**读数逻辑错误**。",
    "4. 重新审视数据一致性：对比厨房温度传感器，其读数也在 2475-2558 之间，与客厅高度同步。这表明全屋环境温度确实在升高。但是，请注意 09:10 时刻，`living_room_window` 被打开（CurrentPositionLiftPercent100ths = 0 表示完全打开，因为 LiftPercent 0 通常指全开，或者取决于具体实现，这里假设 0 为开，10000 为关，或者反之。通常 Window Covering 中 0% lift 是全开，100% lift 是全关。日志显示 06:34 卧室窗帘也是 0，随后有人起床活动，符合早晨场景）。",
    "5. 核心判断依据 - 传感器故障/漂移迹象：尽管温度数值在物理上可能合理（23-25°C），但题目要求评估“目标设备当前工作状态”。在许多智能安防场景中，如果温度传感器读数长期保持在一个非零的固定偏移量，或者读数更新频率异常（此处每10分钟一次，较稀疏），可能被判定为需要校准。然而，最明显的异常在于**数值本身的合理性存疑**。如果这是一个标准的 Matter 设备，2375 代表 23.75°C 是完全正常的。**但是**，如果我们仔细看 09:10 的窗户事件：`living_room_window` 位置变为 0（全开），紧接着 `living_room_window_contact` 变为 True（关闭？通常 Contact Sensor True 表示 Closed，False 表示 Open，或者反之，取决于配置。Matter Contact Sensor 通常 StateValue=True 表示 Closed/Secure，False 表示 Open/Insecure）。",
    "6. 修正推理路径：让我们看 09:10-09:12 的事件链。09:10 窗户打开（Lift=0），Contact=True。09:12 Contact=False。这意味着窗户在2秒内从“开”变为了“关”？或者接触传感器逻辑是反的？如果 Contact=True 是 Open（不常见），那么窗户开了2秒就关了。这种极短时间的开关操作，且没有伴随 occupancy 变化（客厅 occupancy 一直为 0），极有可能是**窗户接触传感器故障**或**误触发**。此外，如果 Contact Sensor 的逻辑是 True=Closed，那么 09:10 窗户开着（Lift=0）却报告 Closed (True)，这是典型的**传感器状态不一致/故障**。",
    "7. 综合结论：主要威胁并非温度本身（23-25度正常），而是窗户传感器在窗户物理开启（Lift=0）时报告了错误的接触状态（True，通常意为闭合/安全），且在短时间内状态跳变。这属于传感器故障。"
