Looking for InVENTer easy control e16 HA integration

Hello forum,

I have several ventilation systems of type “AVIANT” from the company inVENTer in my house.

They are all connected with a central control unit mounted on my wall called “easy control e16” that uses rf 868 MHz to steer the ventilators.

There is a simple mobile app that communicates via bluetooth with that easy control unit e16.

I like to integrate that system to my home assistant.

Is there somebody who has similiar components (inVENTer Aviant with easy control e16) and was able to add it to HA?

I think it must be possible via the rf communication directly to the venilators or via bluetooth to the central unit if someone was able to reverse engineer the protocols.

Thanks for any input!
