Hi everyone,
I’ll try to explain my problem, sorry if I’m unclear.
as the title suggests I have an esp32 (to be exact wt32-eth01) and then I took two cards (R421B16) these cards communicate in RS485 and I only noticed now that they only communicate in HEX, now I haven’t found anything about it on how to do it, I connected them to esp32 via a MAX485 following some diagrams online and it seems to work,
but until I create the commands in HEX from esphome I can’t know, can you help me?
I also have the complete file with examples of the hex commands to give, only that I’m not at the PC now and I don’t know how much it would be useful!
