I've upgraded to Indigo 7 and am playing with the control pages. Now that I have a reflector I decided to look into them.
For the MyQ plugin I've got it set to use the "Light Garage Door Control 2x.png" for the image. It's displaying nicely. But as it's a single image I don't think I can use the two sides to Open or Close the door. So I thought I would overlay the single image with two transparent images and link them to the controls for Open (Unlock) and Close (Lock)
Before I dig into Gimp and make a set I wanted to check to see if 1. This is a viable idea, and 2. There isn't someone who has already done the work ...
If I end up making something up I'll post it here.
