I can program scenes on buttons 1-4 (short press) no problem but cant get the long press or 5-8 to run a scene, what am I missing?
Just figured it out. I will answer myself for the sake of other simpletons like me. Scenes 5-8 are achieved by re-using button numbers 1-4 with “a scene is deactivated” (duh!) 
See also the wiki page; although it could be stated more clearly. Feel free to update the wiki, anyone…
