We are wiring a new home with Sonos ceiling speakers in each room powered by Sonos Amps. We would like to have in the wall rotary volume knobs to control the volume for each Room/Amp. We have used Sonos products since Gen 1, this is our first whole home speaker setup and my wife prefers  to control the volume from a wall switch than going to the app each time. Thanks For Your Help & Have Great Day !
