Inverter does not responde on modbus

[Jxhannes]

Hi!

I installed ESP Home successfully on my ESP and connected it accordingly to the wiring diagram with the Inverter RS485 Port. Sadly, no communictaion is happening as far as I understand.

There are many mesages in the log "Duplicate modbus command found: type=0x3 address=172 count=2" - is this okay?

Where could the problem be? What am I doing wrong?
Wiring shoudl be correct, I checked multiple times. Maybe do I use the wrong TTL to RS485 modules?

got the same issue. How to debug?

// I changed ESP->RS485max tx/rx and is everything fine :)
