Have you got the relays defined under fpp?
They have to be set up under Channel outputs/ other outputs.
You have to assign a channel number that matches what you have an Xlights.
On your xlights setup you have them set as null and you have a few other things that need some help.
We have no idea how you plan on running this so it's hard to advise you without more information.
This is why I mentioned getting into Zoom.
