Sending Messages over MQTT using Node RED
Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.
It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click.
JavaScript functions can be created within the editor using a rich text editor.
A built-in library allows you to save useful functions, templates or flows for re-use.
