What I meant by controller range was the ea-1,3,5 range with the remote for the mesh network. I have had one dealer saying I need an ea-1 at every tv location. I know that would work but is it needed? I don’t care if I have the c4 GUI at every tv location I was hoping maybe 3 ea-1s spread out thru the house would work. One ea-1 going in the a/v rack where I don’t think 4 ir ports will be enough.
