I have two networked MacBooks set up as Remotes. They see the Core (MacMini) and play the Core’s library. One is connected via ethernet. The other via wifi.
However, the iOS app does not see the Remotes. They also do not appear on the Core’s list of zones.
That’s the way it works at the moment. Remotes only see audio devices attached to the core, networked audio devices and local devices they cannot see devices attached to other remotes. IOs remotes cannot see/play local devices either.
I think this will change with RoonSpeakers which I understand is coming shortly.
Thanks @philr – some more info on what’s coming and what’s possible now is here @Andrew_Herrmann.
