Implementation of the VRC720 Vaillant system

[tbazire]

Good morning,
I am trying as best I can to first retrieve the information from my heat pump.

I started to test the HEMS example, I recover the possibilities of my heat pump and options appear on my vaillant application following this link in particular by testing "https://github.com/enbility/eebus-go/blob /feature/experiment-heatpump/cmd/hems/main.go"

only I can't understand the programming logic (I'm "tinkering" but I'm not a developer) I try to help me with GPT but I'm stuck in a loop.

here is what the pump tells me:

Do you have a clue so that I can create a method/interface?
I would ultimately like to be able to export it to integrate it into homeassistant

Thank you in advance for your answers

Hi there :)

This repository does not provide everything you need. Functionalities to support heatpumps are not done yet. Also you would need to implement your own energy management system that uses these (yet) missing functionalities. So without development skills, I fear that you won't be able to do much of this.

Ok, thanks for your feedback :)
