Talk To Everyone In Your Home (Broadcasts)
This next feature I thought was just a gimmick at first, but it's amazing. Google recently released a new "Broadcast" option where you can have every Google Home in the house say the same thing.
If you have more than one Google Home in your house simply say, " Ok Google, Broadcast it's time for bed" and every single Home device in your home will say that message out loud. Letting your kids downstairs know it's time for bed, time for school, or that you're running late from work and will be home in 15 minutes.
You can do this from home, or while you're out and about. This even works by typing a message into Assistant, if you'd like.
