Node-RED自动化场景帮助你快速上手并打造个性化的智能车库系统。准备工作ratgdo与Node-RED的连接在开始之前确保你已经完成ratgdo的硬件安装和Node-RED的配置。首先需要通过MQTT协议将ratgdo与Node-RED连接这是实现所有自动化场景的基础。图1ratgdo干接点接线示意图正确的接线是确保设备正常工作的关键连接步骤确保ratgdo已正确连接到电源和车库门 opener在Node-RED中安装MQTT节点node-red-contrib-mqtt配置MQTT连接连接到你的MQTT broker导入ratgdo的Node-RED示例流程场景一智能车库门状态监控与通知这个场景将实现对车库门状态的实时监控并在门状态变化时发送通知。实现代码[{id:7b4a2c42db6452c9,type:mqtt
