One of the best features of Google Home when it comes to audio is one that I suspect many have not heard of or used. It is called Home Grouping and it allows you to put your Home and Chromecast audio devices into a logical group inside the Home app. Once done, you can give the command to play music on that group and it will play across all of your Home devices. It is a great feature and is easy to setup.
First, make sure you have the latest Google Home app on your phone. Next, make sure that your phone and the Home, and the Chromecast devices you want to add to your group are all on the same network. In other words, you can’t do this while you are on a business trip or on holiday. You have to be home to do it. Finally, make sure all of your Home device and Chromecast devices are turned on so they can be found. With that, let’s get to the How To.
