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",

    "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。

    "推理步骤 1: 检查洗衣机状态日志。在 2026-07-10T10:00:00 时，洗衣机报告 OperationalState 为 1（运行中），随后在 10:20:00、10:40:00、11:00:00 多次报告 CountdownTime 为 2400 秒（40 分钟）。这表明设备正在按计划执行洗涤程序，且倒计时逻辑一致，未出现状态突变或卡死现象。",
    "推理步骤 2: 关联环境传感器数据。在洗衣机运行期间（10:00 - 11:35），厨房温度传感器读数稳定在 25°C 左右（如 10:30 时为 2548 mK = 25.48°C），儿童房和主卧温度也处于正常居住范围（约 24.8°C - 25.6°C）。没有检测到漏水传感器触发或烟雾报警信号，排除了因洗衣机故障导致的水浸或火灾风险。",
    "推理步骤 3: 分析住户行为模式。日志显示入户门传感器（front_door_contact）在 07:48 变为 False（开门），随后玄关和餐厅运动传感器频繁触发，表明住户正常进出和活动。阳台区域除洗衣机外无其他异常活动记录，符合早晨起床洗漱、准备早餐及洗衣的常规生活场景。"

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

## 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。

  "threat_description": "检测到客厅温度在无人状态下持续异常升高，且伴随窗户开启和烟雾报警器未触发（可能故障或阈值未达），存在严重火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，从 03:45 到 08:40，客厅温度传感器读数从 23.82°C (2382mK) 持续攀升至 25.33°C (2533mK)，并在随后几小时内维持在 25°C 以上的高温区间。对于独居老人家庭，这种长时间、无人员干预的温升模式不符合正常昼夜温差规律。",
    "推理步骤 2: 关键证据在于 09:10 分，当客厅温度达到约 25.5°C 时，日志记录显示 'living_room_window_contact' 状态变为 True (True 通常代表接触/闭合，但在某些传感器逻辑中需结合上下文，此处更可能是指窗户被打开导致接触断开，或者日志中的 True 代表‘非正常关闭’状态，但紧接着 09:12 又变回 False。然而，最关键的异常是：在 06:23 厨房灶具关闭后，客厅温度并未下降反而继续上升，且 09:10 分窗户状态发生剧烈变化（0% 开度 -> 0% 开度，但接触传感器翻转），暗示有人试图开窗通风或窗户意外开启，但此时室内已积聚大量热量。",
    "推理步骤 3: 尽管有窗户操作迹象，但直到 12:05 分，客厅温度仍高达 25.34°C，且日志中从未出现 'smoke_co_alarm' 的报警事件。考虑到温度已达到接近人体体温甚至更高的水平（取决于单位换算，若为毫开尔文则 2534mK=2.2K 显然不对，应为摄氏度*100 或类似比例，即 25.34°C），如此高的环境温度下若无烟雾报警，极有可能是烟雾报警器本身故障（sensor_malfunction/safety_device_failure）未能及时响应，或者是火情处于阴燃阶段尚未产生足够烟雾，但高温本身已是严重的火灾隐患。",
    "推理步骤 4: 住户为独居老人，反应能力可能受限。在高温环境下，若发生火灾，老人极易因缺氧或高温昏迷而无法逃生。当前的‘高温 + 疑似设备失效（无报警）+ 异常行为模式’构成了高置信度的火灾风险。"

    "03:45 至 08:40 期间，客厅温度持续单调递增，从 23.82 升至 25.33，且在此期间大部分时间 occupancy 为 0（无人）。",
    "在极高温度（>25°C）持续数小时后，烟雾报警器（smoke_co_alarm）未在日志中产生任何报警事件，提示可能存在设备故障或灵敏度问题。",
    "09:10 分窗户状态突变（CurrentPositionLiftPercent100ths = 0 且 ContactSensor 翻转），表明有人介入或窗户异常开启，但未能有效降低室内积聚的高温。"

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",

  ],
  "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。

    "发现异常点：在12:09记录为None后，12:10的读数突然变为2719（即27.19°C）。这一数值相较于前一时刻（25.26°C）出现了近2°C的剧烈跳跃，且该时间点前后无其他热源设备（如灶具、烤箱）开启的记录（灶具仅在08:59短暂开启并关闭）。",
    "排除环境因素：客厅和卧室的温度在同一时间段内保持平稳或缓慢下降趋势（客厅从25.41°C降至25.04°C），说明整个房屋并未经历整体升温。因此，厨房局部的急剧升温极不可能由外部环境引起。",
    "结论：这种孤立的、非物理性的数值突变最可能的原因是传感器硬件故障、电池电量不足导致信号干扰，或者是Matter协议层的数据解析/上报错误。"

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": [

}
```

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. 分析温度数据的合理性：Matter协议中TemperatureMeasurement.MeasuredValue通常以厘氏度（centi-degrees Celsius）为单位，即除以100得到摄氏度。日志中大部分读数为24xx-25xx，对应24.2°C-25.5°C，符合夏季室内舒适温度范围。",
    "2. 识别异常模式：在13:15、13:35和13:55三个时间点，living_room_temp_sensor分别报告了2920 (29.2°C)、2940 (29.4°C) 和 2960 (29.6°C)。",
    "3. 排除环境因素：在同一时间段（13:00-14:00），客厅空调已开启（OnOff=True），且同楼层的厨房温度传感器显示温度从24.99°C下降至24.70°C，主卧等其他房间温度也呈正常下降或稳定趋势（24.9°C-25.0°C左右）。如果客厅真的达到29°C+，厨房和其他区域不可能保持低温，除非存在极端局部热源，但这与空调开启状态矛盾。",
    "4. 结论：这种突发的、孤立的、且与其他所有传感器数据完全不一致的高温读数，极大概率是传感器硬件故障、校准漂移或通信数据包损坏导致的错误值，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
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": [

}
```

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. 分析温度数值格式：日志中的温度值（如2267, 2532等）明显不是摄氏度或华氏度的常规表示。在Matter协议中，TemperatureMeasurement Cluster的MeasuredValue通常以厘度（centi-degrees Celsius）为单位，即实际温度 = 测量值 / 100。例如，2532代表25.32°C，这符合家庭环境的正常室温范围。",
    "2. 识别异常数据点：在[2026-08-01T14:05:00]时刻，living_room_temp_sensor报告值为-500。根据单位换算，这代表-5.00°C。考虑到同一时间段其他房间（如主卧、厨房、儿童房）的温度均在24°C左右，且客厅此前温度为24.30°C，突然降至-5°C极不符合物理规律，除非发生极端灾难性事件（如爆炸导致瞬间冷却，但这通常会伴随烟雾报警）。",
    "3. 排除环境因素：检查关联设备状态，此时段内所有运动传感器均显示Occupancy=0（无人），门窗传感器无开启记录（虽然日志未直接列出门窗状态变化，但温度骤降通常伴随开窗，若开窗应有接触传感器触发或温度缓慢下降而非瞬间跳变至负值）。此外，-500是一个典型的传感器故障代码或通信丢包导致的默认/错误值（某些传感器在无法读取时会返回特定错误码，或者ADC采样错误）。",
    "4. 结论：该异常读数并非真实的环境温度变化，而是传感器本身或其数据传输链路出现了故障。"

    "同一时间点其他房间温度正常：master_bedroom ~24.65°C, kitchen ~24.59°C, kids_room ~24.73°C",
    "前后数据对比：14:00为2430 (24.30°C)，14:05突变为-500 (-5.00°C)，14:10恢复至2440 (24.40°C)"
  ],
  "recommended_actions": [
    "1. 检查客厅温度传感器的电池电量或电源连接，尝试重启设备。",

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": [
    "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": "客厅温度传感器出现严重读数异常，包括瞬间跳变至负值及数值剧烈波动，表明设备硬件故障或通信错误。",
  "reasoning": [
    "1. 分析温度数据趋势：从08:10到14:00，客厅温度在25°C左右缓慢下降，符合夏季午后室内自然降温规律，且与其他房间（如主卧、儿童房）的温度变化趋势基本一致，说明环境本身无突变。",
    "2. 识别关键异常点：在14:00:00记录中，客厅温度传感器突然上报值为2430（即24.3°C），紧接着在14:05:00上报-500（即-5.0°C）。-5.0°C对于夏季室内环境极不合理，属于典型的传感器故障或数据溢出/解析错误。",
    "3. 验证后续行为：在14:10:00，数值又跳回2469（24.69°C）和2440（24.4°C），随后继续缓慢下降。这种‘正常->极端异常->恢复正常’的锯齿状波动模式，排除了真实物理环境变化的可能性，确认为传感器自身故障。"
