The velux equipment uses incontrol protocol that has revolving codes, so normal remote learning solutions won’t work. I use HomeAssistant as my main control software which controls my bond bridge. I am in the process of adding a Velux Netamo control hub for my Velux skylights. You can use the homeAssistant HomeKit integration to control it which would allow you to use Alexa, Google Home etc. The homeassistant documentation for the Velux integration discusses this option.
