Saswell Ventilation HVAC controller

I’m considering purchasing a ventilation system and it appears to come with this controller/remote.


I’m guessing that I may be able to send command using an RF module but I don’t think it’s going to let me report the fan speed, mode etc back to OpenHAB.

Does anyone have any experience with these or similar systems?

Maybe there is a replacement controller I could use instead that would allow better integration of OH?
