I have found documentation on modbus from my inverter. I’m trying to connect to modbus and read data online (eventually I want to use ESPHOME + TTL/RS485) Initially I use the modbus pool program and test the connection. Unfortunately all my attempts turn out to be wrong, I get CRC ERROR or time out.
Can any of you verify from the documentation that the correct values are entered in the Modbus Poll?
Maybe there is another way to test communication? Do you have a proven solution?
