Editing flows

Open

One can easily add further UI elements if needed. In the backend you will see flows, organized as interconnected nodes. There are various types of nodes provided by the community or Node-Red developers: javascript or python3 functions, HTML templates, shell commands, buttons, ROS publishers & subscribers and many more.
