Node-RED Programming

In this chapter, we will go over the Functions Tab of Playground


The Functions Tab uses the Node-RED tool for working with TOWER and other devices.

We can't cover everything about this tool in this tutorial so if you want to learn more, you can visit the Node-RED documentation.

Functions Tab

You should see a screen that looks like this


On the left side of the screen, there is a list of nodes that you can use for multiple actions in the Node-RED programming.


There are a lot of nodes available for Node-RED that you can install but you should be able to work with TOWER devices just with the available preinstalled nodes.

You can use nodes for multiple functions. As an example, there is a data visualization that is tightly connected with the Dashboard Tab.


To learn more about Node-RED flows please visit our projects on Each project that uses Node-RED has a lot of information about how to work with it.


To learn about the next tab visit Data Visualization.

Video Tutorial

If you prefer a video guide, you can watch this video for the older Playground version, but it works the same.
