Integrate Somfy Roller Shutters with HA

Hi all, I have multiple Somfy roller shutters with remote controls. I want to use Home Assistant to open/close them (so I no longer have to use 4 remote controls). I don’t have a Somfy/Tahoma hub. HA runs on a Raspberry Pi. How can I build this integration so it “records” what the open/close/pause (i.e., half way stop) buttons transmit?

What do you guys recommend?

Much appreciated!

Do you have RTS or IO devices?

RTS: GitHub - rstrouse/ESPSomfy-RTS: A controller for Somfy RTS shades and blinds

IO: buy a TaHoma Switch
