Tom,
Since you select the brand in one location, is there any way to control two different brands? I have two doors and just replaced my right GDO with a Chamberlain. What happens if I get a good deal on a Craftsman or Liftmaster when I replace the other one? I am not sure you can have two occurrences of an app running on a Vera. Will the app recognize the other brands or am I locked into Chamberlain now?
