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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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。

    "1. 分析重点设备状态：日志显示在 2026-07-19T08:00:00 至 08:05:00 期间，kitchen_smoke_alarm 的 SmokeCoAlarm.TestInProgress 属性由 True 变为 False，且随后 ContaminationState 为 0。这明确表明烟雾报警器正在执行自我测试程序（Self-test），这是智能家居安全设备的标准维护功能，用于验证传感器灵敏度和通信链路是否正常。",
    "2. 排除火灾风险：虽然设备处于“测试中”状态，但日志中并未出现 SmokeCoAlarm.AlarmState (如 Fire Alarm) 被触发的记录。同时，同一时间段内 kitchen_temp_sensor 的温度读数在 2530-2540 (即 25.3°C - 25.4°C) 之间波动，处于非常稳定的舒适室温范围，没有任何温度急剧升高的迹象，排除了因烹饪疏忽导致的火灾风险。",
    "3. 结合环境上下文：在测试发生的时间段（早上8点），所有房间的运动传感器（occupancy_sensor）均报告 Occupancy = 0，表明家中无人。在无人状态下进行设备自检是常见的自动化策略或用户远程操作的结果，符合正常行为模式，不存在入侵或异常活动。"

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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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",

    "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. 烟雾报警器状态分析：在 08:00-08:05 期间，kitchen_smoke_alarm 的 TestInProgress 属性由 True 变为 False，且 ContaminationState 为 0。这表明用户或系统执行了标准的烟雾报警器自检程序，而非火灾报警（通常伴随 AlarmState 变化），属于正常维护行为。",
    "2. 烹饪活动分析：09:02 厨房灯开启，09:03 灶具 (cook_surface) 开启，09:25 灶具关闭。整个烹饪过程持续约 22 分钟，符合正常的早餐或早午餐准备习惯。",
    "3. 环境与安全联动：在烹饪期间（09:03-09:25），虽然温度传感器读数有波动（受热源影响），但并未触发烟雾报警器的报警状态（TestInProgress 已复位）。09:25 灶具关闭后，后续日志中无异常高温或烟雾数据，表明烹饪过程安全可控。",

    "推理步骤 2: 在传感器恢复报告数值后（T09:05:00 起），厨房温度读数迅速攀升至 254°C - 255°C 区间。考虑到 Matter 协议中温度单位通常为 0.1°C，2549 代表 254.9°C，这对于普通家庭厨房是极不正常的物理状态，除非发生了严重火灾或传感器校准完全错误。",
    "推理步骤 3: 结合上下文，用户在 T09:02:34 开启了灶具 (cook_surface)，并在 T09:25:00 关闭。如果传感器真的检测到 250°C+ 的温度，烟雾报警器应在几分钟内触发警报并进入报警状态，但日志中仅显示了一次正常的自检 (TestInProgress)，未显示任何火灾报警事件。这表明传感器读数极可能是由于硬件故障导致的漂移或错误，而非真实的高温。",
    "推理步骤 4: 这种‘高温读数’与‘无火灾报警’的矛盾，加上中间出现的 'None' 数据点，强烈指向传感器本身出现了故障（Sensor Malfunction）或严重的信号漂移，导致无法准确监测厨房安全状况。"

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。

  "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",

    "4. 传感器数据稳定：温度传感器读数在24-25°C左右波动，符合夏季室内舒适温度范围；虽然09:03和09:49出现None值，但随即恢复，可能是网络延迟或瞬时丢包，未构成持续性故障。"

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。

系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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",

监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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 4: 结合上下文，虽然存在 unattended_cooking 的风险场景，但核心异常在于传感器数据的不可信，导致无法准确判断是否真的发生了过热或火灾风险，因此首要问题是传感器故障 (sensor_malfunction)。"

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。

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": "检测到洗碗机启动并进入倒计时运行状态，同时厨房温度传感器读数随设备运行出现合理波动，所有行为符合正常家电使用逻辑，未发现安全风险。",
  "reasoning": [
    "1. 分析核心事件：日志显示在 14:00 时，kitchen_dishwasher（洗碗机）的 OperationalState 变为 1（通常表示运行中或激活），并在 14:30 时出现了 CountdownTime = 1800（剩余时间30分钟）。这表明用户正在正常使用洗碗机进行清洗程序。",
    "2. 关联环境数据：在洗碗机运行期间（14:00 - 14:55），厨房温度传感器读数从 2471 下降至 2450 左右。虽然数值看似下降，但考虑到 Matter 协议中 TemperatureMeasurement 常以厘氏度（centi-degrees Celsius）为单位，24xx 可能代表 24.x°C 或特定编码下的相对值。即便假设单位为摄氏度（极不可能，因室温不会这么低且变化剧烈），这种小幅波动也可能是由于空调制冷、开窗通风或传感器自身精度误差导致，并非火灾或过热迹象（烟雾报警器无报警记录）。若单位为厘氏度，则 24.5-24.7°C 是舒适的室温，微小波动完全正常。",
    "3. 排除其他威胁：全屋运动传感器在 13:30 和 14:00 均报告 Occupancy = 0，说明家中无人或人员处于静止状态（如午睡）。在无人的情况下启动洗碗机是常见的自动化场景或定时任务，不属于“unattended_cooking”（无人看管烹饪，通常指灶具）风险。没有门锁异常、漏水报警或烟雾报警，因此不存在入侵、火灾或水患风险。"
