MyQ Smart Garage Opener/closer

MyQ Chamberlain Smart Garage Control, Wireless Garage Hub and sensor w/wifi and Bluetooth. This gadget has been a great and expensive buy. Worked super well for my pet sitter while I was out of town. She called to let me know that she was at my home and I let her in via the app on my phone! No extra keys or codes to remember. Brand new, never opened. ccidentally purchased 2 and never returned it.
