Hi,
these devices seem be barely in use, which i dont understand since they are really handy devices when it comes to ModBUS in no WIFI areas.
They are simply esp32 units in a DIN rail case. Since the documentation is very…lets say…basic you have to take the adventure on your own. I spoke to the Heltec guys about a paylaod decoder but they where out of clue, so i took the chance to write my own. Now we have a up- and download decoder fully working.
I released a github repo with some basic info:
I hope it can be usefull for somebody…
