Well I got the Big Red.
When you push the button momentarily it sends an "A5" (my unit code for it) then a "A on" as you keep the button down it sends a " A bright 5%", followed by "A dim 5%", followed by a "A bright 5%", followed by "A dim 5%", followed by a "A bright 5% ". From then on it sends "A5" "A on" every second or so. I'm going to try and figure out what to do with those. At any rate it will work for leaving and coming. I need to think about the emergency part.
