At its annual developers conference, Google expanded its line of Assistant home devices and renamed the entire family. The new Nest Hub Max is the 10-inch version of the existing Google Home Hub with some added features, and now the entire Assistant device family will fall under the Nest branding. So the Home Hub will now be called the Nest Hub, and so on.
