Assuming you have the Firefly system.... here is the procedure.
When you go to the menu that shows you the wireless switch connections, you want to touch and hold the one with the red status for about 8 seconds and then release.
You will then see a menu appear that says pair. Touch the pair button on the screen and then you have 30 seconds to go to that specific switch and press and hold any two buttons simultaneously for 5 seconds.
The display should then say that switch is paired but it may take 10 minutes until the status turns green. Do this for all of the switches with a red status.
It is possible your batteries in the switch need to be replaced. Just remove the switch from the wall plate. They are 2032 batteries. I just ordered a 10-pack for $8 on Amazon to keep in the coach.
