Core Infinity board

I dont see why you couldn't use the companion for that purpose. Even if the remote has to go back, you can still control it with the IOS  application. One should in theory just need to reconfigure it with the online Configurator. Of course this is all theoretical but that is what I was thinking of doing with it as well.

If the slave dont have the ethernet board how will it be able to connect to the network and be controlled by the app?

Ooops, good point....guess that shoots that idea down as I don't know of any other way to control the volume without a remote...

Well, as long as there was a sensible volume set (including startup/input select volume) before the remote got sent off, you could use software volume control as a stopgap. Source change might be an issue though.....
