I’m still learning about Helium, have a couple of gateways and experienced with Data Only and PoC’s ones. Recently I helped a relative to buy his S2120. I hope I can help him to configure it remotely, because he needs it for a small farm. I think there should be a way to edit the formulas/decoder. I remember I had to do that with another brand LoRaWAN tracker with Helium Legacy console (LNS) and Datacake.
That is a wonderful analogy about the issue!
