Control roller shutter

Hi
I have finally successfully installed vera edge and the rfx controller for some comfy blinds and cloned the remote.
I was wondering if I can control a roller shutter now too. The shutter works on 433 frequency and I have cloned its remote to new Fobs in the past.
My questions are - how do I know which protocol it uses? how would I clone the commands to the rfx?

many thanks :slight_smile:
