Looking to set up a small conference room, I will be using a projector that will lower from a lift, 4 blinds, 2 banks of recessed lighting and a motorized screen. I was planning to use an EA-1 with IO extenders to operate the blinds, screen and projector lift via relay contact. Lights I will be using lutron switches with a hub. My question is, will an EA-1 be sufficient for this application? Im not sure how many extenders I can add before I start to bog down the system.
