Hello everyone, I have the problem that the integration does not have access to the Recovair 260/4 ventilation system. What do I have to set so that it is also displayed in the Home Assistant? It is visible in the myVaillant app and I can make settings. Unfortunately, I can't make sense of the instructions.

Does the fact that I can't see the ventilation have anything to do with this error message?
