I'm so stupid I searched Bitcoin Forum to find how to get this AFAIK installed

I just clicked through all the menu pages in AntMiner S1 LuCi and I can't see how to "
configure it to allow API access from your IP."
But, I just realized that I can right-click on a Network device and Switch between its 3 internal pools. It list them as the text following the first dot. Be nice if the whole URL was listed. That's a great time saver, thanks

My pleasure! I do plan on adding more integration there. There's a lot of stuff you can do via the RPC API so pool switching is just the start.
