I have around 14 different Sonos speakers operating across one network controlled by the S1 controller. I want to add a SONOS Roam for the bathroom however I understand that it can’t be added to the S1 network (please someone confirm this or not). I have a two part question: a) Can I set up and operate both S1 and S2 on the same network and b) can i install and operate both S1 and S2 apps on the same IPhone?
