I have speakers in every room currently controlled, sort of, by a CONTROL4 unit. I hate it. The interface is atrocious and tens of thousands in Control4 equipment doesn't accomplish what I could do with the flick of a switch. I have echo dots in many rooms of my home. I want to rip out the entire Control4 system and its horrible music software. I now have all my music on a PLEX system. What is the best interface for controlling all this? Reading some on the logitech harmony...would that do it? I just want to listen to a song in any particular room without jumping through hoops!
