If you need more then the eight relays for DLI or KMtronics, then I showed in the previous examples, I know both DLI and KMtronics have other models with more relays.? These devices are more expensive, but you get a very versatile?and proven system, that can be accessed?via multiple ethernet methods.
Also, you could use a GPIO based relay board (cheap) and control that with a Raspberry Pi 3 (affordable). ? Then use ethernet cable or WiFi to connect the remote Beverage Raspberry Pi to your network.? Then using an MQTT server, you can access the remote Beverage controller from a Node-Red Raspberry Pi in your station, which would hold your Flows and Dashboard.? I have flows for this sort of configuration.
