Once in the Devices tab, you'll see a list of supported partners with a new entry for ecobee. At the time it was compatible with Amazon Alexa, and Google Assistant wasn't available until just this week, so there was certainly a little bit of a wait for those who wanted ecobee's thermostats but already had Google Assistant-powered products with which they would hope to use.
All devices must be signed onto the same Wi-Fi network, and at least one member of the household has to be signed in to each of the Google Home speakers. This rollout is specific to countries like the US, UK, Australia, and Canada.
The feature can be used whenever the user wants pass along a message to notify their friends or family. Now you can broadcast a message to your family throughout your house filled with Home devices.
Google Assistant is getting a new feature that will probably make moms and housewives all around the world very happy. This is especially useful for those that live in a big house with many rooms without intercoms and those that have a hard time to gather everyone for a meal.
This will let users broadcast messages through voice commands, no matter from where you access the Assistant. Once done, the message will be played on all the devices tied to the account. All one needs to do is say "Ok Google, broadcast" followed by the message, which will then broadcast on Assistant-enabled devices like Google Home. It'll even ring a dinner bell if you say "OK Google, broadcast it's dinner time".
The ecobee4, ecobee3 lite, and ecobee3 are all slated to receive Google Assistant support. The iPhone X, Apple's most recent flagship, includes Face ID, a feature that is expected to be incorporated into all of the company's 2018 iPhones.
