The MyQ Smart Garage Hub is a simple, standalone WiFi hub that sits in your garage and communicates with your existing garage door opener (and an open/close sensor you stick on the door itself). If you have a wireless garage door opener in your car, the MyQ Hub works the same way--you use the Learn button on the main unit to "teach" the MyQ Hub how to communicate with the opener, allowing you to open the door without a hardwired connection. Only instead of a little button in your car, the MyQ hub gets its signal from your phone, using your home's WiFi connection. It supports Amazon Key for in-garage deliveries, as well as Google Assistant, IFTTT, and a few other smart home platforms. Here are the MyQ Smart Garage Hub's specs: Best of all, Amazon currently offers a $30 credit after your first in-garage delivery with Amazon Key--which means the Smart Garage Hub pays for itself after one in-garage delivery, provided you live in a supported area.
