Hey Peter,
Having just completed setting up all my Somfy window blinds, I felt like I needed to chime in on your question. A few years ago Somfy introduced the Autoview and Easyview motors as a replacement for the RTS motors. Whereas you ordered you blinds about the same time as I ordered mine, you may not need an interface. The good news is Autoview are Z-Wave devices directly compatible with the ISY-994 (with the Z-wave option). There is the possibility that your blinds have the easyview motors, in which case they are not compatible with the ISY and Somfy isn't aware of any compatible hubs. Let me know if I can help you out any further.
