I'd like to see how to two paired up sound with movies in my living room. I use an Apple TV exclusively so I know it's possible to get working. I think I will wait for the HomePod mini next year before I start buying multiples for the house.
I purchased my 1st one for the living room, then 3 more for the bedroom, basement & kitchen. Im hoping ios12 will allow intercom capabilities before i put one in the kids room.
