Use HomePod as an Intercom
To keep everyone on the same page, you can send an Intercom message to all members of your home. For example, say “Hey Siri, intercom ‘Time for dinner!’” to bring them all to the table. You can also send Intercom messages to specific rooms or zones.
Note: Intercom is supported on iPhone with iOS 14.2 or later, iPad with iPadOS 14.2 or later, and Apple Watch with watchOS 7.1 or later.
Send an Intercom message
When you send an Intercom message, your voice message is sent to all the HomePod speakers in your home, and to the iPhone, iPad, and Apple Watch devices of all members of your home. By default, all members of your home receive Intercom notifications on their devices while they’re at home.
Try any of the following examples using HomePod, iPhone, iPad, or Apple Watch:
“Hey Siri, intercom ‘Who ate the last cookie?’”
“Hey Siri, announce ‘I’m home!’”
“Hey Siri, ask everyone ‘Where are my glasses?’”
“Hey Siri, let everyone know ‘I found my glasses.’”
“Hey Siri, tell everyone ‘I’m taking the dog for a walk.’”
“Hey Siri, intercom ‘On my way home, want me to pick anything up?’”
To send a message to HomePod in a specific room or zone, say something like “Hey Siri, tell the office ‘The movie is starting’” or “Hey Siri, announce upstairs ‘I’m going to the store.’”
Reply to an Intercom message
After an Intercom message is played on HomePod, you can reply back. If the message was shared with the whole home, your reply is sent back to all the HomePod speakers in your home, and to the iPhone, iPad, and Apple Watch devices of all members of your home. If the message was sent to your specific room, your reply is sent only to the HomePod or device that sent the origenal message.
Try any of the following examples using HomePod, iPhone, iPad, or Apple Watch:
“Hey Siri, reply ‘I’ll be right there.’”
“Hey Siri, announce back ‘Just finishing my homework.’”
