Google Home is a voice-activated speaker powered by the Google Assistant. Ask it questions. Tell it to do things. It's your own Google, always ready to help. Just start by saying, "Ok Google" to enjoy music, get answers straight from Google, manage your everyday tasks, and easily control smart devices around the home. Google Home seamlessly connects with your Nest thermostat. With a simple voice command, Google Home can change the temperature without you needing to lift a finger.
