Just got my dashboard working - couple of live graphs and 2 thermometers all updating from data on a diff server - running via gunicorn - even looks great on my phone! I am confident this product will be getting used in as many of my future jobs as possible - even the ones that dont really need a dashboard 
Thanks all at Dash, especially Nicolas Kruchten - always nice to get speedy positive help.
Hope everyone enjoys their weekend. Finally I am off to my bed.
