All great observations. Haven't gotten to the chore yet, with holiday wrappings taking priority on the buss. I might also look at the MKR ETH and MKR ZERO but I'll need to find a way to host a web page on the board if I can. This was cool: https://forum.wiznet.io/t/topic/6563.
Nice part of the YUN (and maybe the shields) like this:
GitHub - SapientHetero/Ethernet: Ethernet Library for Arduino
The Yun can run PHP as it handles all my data display just fine. Happy Holiday.
