Epever offer a
wifi adapter that may be worth considering depending how hard it will be to run a cable.
I explicitly wanted to run cable, so I went down that path.
Also, I wasn't sure if the OEM device might be 'too smart' and prevent me talking to multiple SCC's. And they only talk about their mobile App which I didn't want to use.
Anyway, the difficulty will be running the cable. Once you've done that, the setup is easy(ish).
I couldn't find any reference online to the required settings, so I fumbled around until it came to life - I can save you some time there!
I'm doubt I selected 'the best' RS485-Ethernet bridge, but it was cheap enough and it does work. I selected this one based on their support offering the required Virtual COM port driver (just easier than kludging random parts together).
In terms of cost: 30~50usd depending on what is already in your junk box.
