Chamberlain MyQ smart garage hub with door sensor. This allows you to turn any old garage opener into a smart opener that can be controlled and monitored via the free MyQ app. I had it briefly connected to an old opener and it worked great until we installed a new opener with this function built in. Therefore, I no longer need this remote which is in brand new condition and functions perfectly.
The items sells for $30 + tax. Get this like-new for $20.
