Finally, to broadcast between Google Homedevices you need to ensure "Do Not Disturb" mode is disabled. That said the wait is now over and anyone who may have held off on a device like the Google Home or an ecobee thermostat can confidently purchase either or both knowing that they will work together. Google adds that the feature will roll out to other languages soon.
Starting today, you can broadcast your voice from your Assistant on your phone or voice-activated speaker, like Google Home. Now you can broadcast a message to your family throughout your house filled with Home devices.
Since introducing the world's first smart thermostat in 2009, ecobee has enabled consumers to control their home comfort any time and from anywhere while reducing energy use.
The message that you broadcast will play on all Google Homedevices that are signed into the same Google Account. It'll even ring a dinner bell if you say "OK Google, broadcast it's dinner time". In other words, you can only send a message through your phone.
Duong and Do says that if you are leaving the office and want to inform your family that you are coming to the home, then you can just say 'Ok Google, broadcast I'm on my way home!' to your phone's Assistant, and it will broadcast to your Google Homes.
See Google's help center for more examples on how to use this feature. The feature is rolling out to Google Assistant-enabled smartphones and smart speakers set to the English language in the US, Australia, Canada, and the UK.
