And Apple has just released Intercom for the large HomePod devices:

We covered the new release here. Still need to do more testing with Intercom.
This Macrumours article has a good description of the new Intercom feature:
A couple of take-aways..
IPhones and iPads won’t work until iOS 14.2 is released
It won’t work if the Homepods are a stereo pair
Jason Snell has posted a review of the HomePod mini.
Our (well, mostly Tonya’s) experience so far is that it just works like our larger HomePods and sounds great.
