Hi has anyone at least dealt with reading the values from this pump I have a USB converter to RS485, I was thinking and I can’t think of how to display the communication that takes place between the display and the heat pump, unfortunately I didn’t find either the documentation for the pump or how to help HA intercept the communication

I found this but I don’t know how to enter the reading
I’m interested in the register 40002,32005,32006,32004
