ComfoConnect Pro

Hardware

Hi,
I am about to buy a Zehnder ComfoAir Q350 and I found ComfoConnect Pro for sale.
From some data sheets that seems to be alternative to ComfoConnect LAN C, so I think it is compatible with Home Assistant.
Have any of you tried it? Does the integration also work with ComfoConnect Pro?
Thank you.

The ComfoConnect Pro is a new interface replacing the LAN-C I think. It has more facilities to integrate with commercial Building Management Sytems as well as home environments with the Zehner App.

It’s expensive… There are open source projects that will give you an interface for Home Assistant for much less (about £20)

Can you suggest alternatives a to the comfoconnect pro? Thanks

Hi there @jrviz , I’m interested on the open source project to give an interface for Zehnder ComfoAir Q350 for £20. Could you please give me some info about this?

How did you do it finally @SikeyMael ?

Thanks!

I have had this running for about 6 months. In the summer I had some automations in the hot weather where the fan would be boosted night and morning when the outside air temperature was below the internal temperature and it was above a threshold.

So james, you have ComfoAir Q350 with just the ESP32 interface (like 20 bucks) and no confocconect interface, just the one you linked and you can control and monitorize almost everything? Is this right?
