Raspberry Pi 4 Setup to controll Elero Shutters

Dear Community,

I’m to this forum and would like to know what Hardware do I need to make the Elero Shutters working and running with OpenHAB and aditional USB 868 Receiver if needed.

Do I need the Original Elero Transmitter Stick to be able to communicate with the Elero Shutters?

Thank you for your help and sorry if the questions seem stupid.
