Alan,
Wow!? That's going above and beyond!? I have only taken a quick look at it, and only see a minor issue.? It appears that once the AUX is turned on (Green) that there is no way to turn it off.? Granted, I'm only playing with it via the dashboard (and I'm operating my shack PC remotely, so there is no hardware, other the the RasPi connected).
