Problem with HA connection

[kirilldem]

Hi elupus,

Thanks for this awesome software! I have bought the lilygo rs485 device to connect to my F730. I can connect to it from a separately hosted nibepi but having issues with HA connection. It is probbaly due to my target and source settings. Any ideas what I can change to connect?

I get the following error in HA:

The model selected doesn't seem to support modbus40

It may well be that I have too much stuff in my ESP configuration as I combined your full configuration example and the lilygo example. This is my ESPhome configuration:

That error looks to be missing parameter definition for that model in the communication library we use: https://github.com/yozik04/nibe

You can test with pump model F1155 just to verify if that is the issue. It will give you wrong list of available parameters, but i dont think you should get that error.

Test with F750 it is closer and should work.

Choosing F750 worked! Thank you!
