Looking for audio advise. The townhouse I just purchased was a model and the builder installed speakers in the ceilings and the hookup in a closet.Looking for audio advise. The townhouse I just purchased was a model and the builder installed speakers in the ceilings and the hookup in a closet. The sound is great but you can only turn volume up/down in each zone by physically walking to each wall switch. I’m looking for a way to be able to control the switches from an app (currently you have to manually turn the volume up/down). I had a company come out and tell me I would have to rewire the entire system. Does anyone have suggestions on switches I can install that would hook up wirelessly? I don’t know the type of system but I thought he said “Ross. ” Any help is appreciated!
