+1 for the Anthem
I used it for a few months when I got the first 520 for my living room system and it worked well. However I added a second 520 for my basement system and the app doesn't distinguish well between the 2, even though you can designate different AVRs in the app, so I have stopped using it. Presumably that wouldn't be an issue if he only has 1 unit. I don't really do the Home House thing much anymore anyway.
