How to use Somfy IO blinds

Hi,
I have Somfy Oximo Blind motors and Somfy Smoove IO remote controls. Actually these controls can control only one motor. I want to control all motors of a room and all motors of the whole house at once.

I want to control all blinds of a room or of the whole house by Home Assistant and by the hardware remote controls.

Is it possbile somehow to achieve this by using Home Assistant?

if you can find them in this manual, you can control them with RfxTrx

It’s the newer Somfy IO which is using 868 MHz. Seems not to work with RfxTrx.
