How to bring data from MySQL to Node red in a dashboard

I already have the database ready and it registers everything but I want it to be shown on my dashboard

Hi 22JES, welcome to the forum.

Node-red dashboard is not installed by default. You can install it via the hamburger menu, Manage Palette.

It has lots of ways of displaying data, eg text, gauges, graphs...

You will need a SELECT statement to retrieve the data and some sort of idea how you want to display it.
