@mfalkvidd Is there a tutorial on how to accomplish this? When I go to the MQTT tutorial, it says to build an Ethernet setup first, followed by setting up either a DNS or static IPs, along with using ESP8266 libraries.
My Arduino modules will initially be Nano's. The only WiFi or Ethernet will be the ones built into the Rpi, used solely for accessing NodeRed. I'm wanting all communications in the system itself to be via the RS485 network if possible.
