Alongside the HomePod mini, Apple introduced a new Intercom feature that’s designed to let Apple device owners communicate with one another throughout the home, sending messages to specific rooms, areas, or people.
Intercom works with the HomePod, HomePod mini, iPhone, iPad, Apple Watch, AirPods, and even CarPlay, so you can dictate a voice message on any of your devices that you can have delivered to a single person in the family or all family members.
How to Set Up Intercom
After updating to HomePod software 14.1 and iOS 14.2, which is still in beta testing at this time, Intercom can be set up in the Home app. Intercom works if you have a HomePod or another compatible device, and there is no dedicated interface on the iPhone for using Intercom outside of the Home app.
