By the looks of it, they only support a web interface so you could tackle this from a couple of angles. First option would be to to a bit of digging into the sort of web requests that are sent to the relay to carry out certain actions, and use one of the UDFs here that allow you to easily send POST/GET requests as per a web browser. Or, you could create a "hidden" IE instance and sort of "click" the links to make it do what you want. (Check out the _IELinkGetCollection and _IELinkClickByIndex functions).
