I have a Zehnder ComfoAir Flex 350 MVHR unit that I’d like to integrate into HA. I know there is an integration for the ComfoAir Q, but the Flex is a newer model, which is more compact, and so I don’t think it has the ComfoConnect LAN C bridge needed. It only connects via wi-fi as far as I’m aware - though I might be wrong. Has anyone had success with integrating this unit into HA?
