At the moment domes with a Velleman controller, mine included, can use only the LesveDome ASCOM controller. The problems with LesveDome is that the source code is unavailable, it is Windows only, and is ASCOM instead of the much more portable INDI.
I’ve written my own Dome controller using the ASCOM Alpaca standard. My code runs on a Raspberry Pi. The Alpaca initiative is fully portable as it uses a JSON/REST API and therefore is no longer Windows COM specific.
