I installed the lift master 8500W earlier this year, and MyQ works very well with the iOS app available.
I am on Indigo 7.3.1, and have the latest MyQ plugin installed. I consistently get an error that indicates a username or password error. Have disabled and re-enabled the plug-in to no avail.
Am I wasting my time here trying to get MyQ to work? My experience with these types of issues with H.A. is that they just never get solved, and you just need to move on.
