Jim Dalrymple, writing for The Loop:
The short answer is no. You can’t make a stereo pair of a HomePod
and a HomePod mini. You can make a stereo pair of two HomePods or
two HomePod minis, but you can’t mix and match the two products.
Now, if you have a HomePod and a HomePod mini in your house, they
will work together so you can play music throughout the house or
use the intercom feature. So, they do work together.
This makes sense — to create a stereo pair, you need to pair two of the same HomePods. But for just playing the same audio in multiple rooms, all HomePods work together.
There is an update coming for HomePod that will add features
announced today as part of the HomePod mini launch. Those new
features include Intercom from one HomePod to another, personal
update, Maps continuity, multiuser support for Podcasts, support
for third-party music services as they become available.
No word from Apple on when we might expect these features, other than in the future. That might sound snarky but I don’t mean it to be. I think there’s a lot of coordination required for these features — updates to iOS, tvOS, and the HomePod’s OS — and “coming soon” is just an honest answer.
