Thanks, Felix
That has at least shifted my confusion. I need to figure where I need to back out of changes I made. I also need to tidy up the files on my laptop. It's getting pretty chaotic.
My RasPi-Gateway/LCD is working well as far as I can tell. It's installed in an enclosure similar to your Acrylic sheet affair only in two modules, one with RasPi and LCD, the other withATXRaspi and Moteino. I'll install GarageMote today and see how that works. It works on the Bench with info displayed on LCD from GarageMote and MailboxNotifier. Haven't really tested it in a browser but indications are that it'll work.
