Somfy rts gateway for homeassistant

Hi
i am not skill in radio frequency
i would like to build a gateway between my homeautomation system (like homeassistant) and my somfy technology Radio Somfy RTS 433,42 MHz (like blinds, shutter, etc).
i can manage my somfy RTS equipments with my remote control but it should be great to manage with my homeautomation system

What is the best choice to build such gateway ?
Do you have links for my to start ?

thanks in advance

Here is one for you. It has all the radio comms and configuration built in for under $15. It also includes a Home Assistant integration.
