Hello,

I have a Issue with the BUS-Connection. I connect the Bus to the correct port but it have very much issues on the rx.

Can someone help me?

I'm using a esp32 "MH-ET Live 32" on a "https://github.com/rocksolidsr/esp-ems-board/tree/main" to a "Logamatic MC110"

It's 99% a wiring problem. Did you switch Tx/Rx? Is it compatible with the circuit board you built?
