How to control non motorized Hunter Douglas windows

I want to control about 15-30 windows which currently are non-motorized Hunter Douglas window treatments. There is a string loop which opens, closes, and tilts the shades. Is there a zwave motor adapter I could attach to the string loop to control these shades? Looking for something compatible with ZWave out of the box, nice looking and not too bulky, and of course cheap as possible due to the number of windows I plan on controlling.

There are not Z-Wave solutions for this that I know of. There is Add-A-Motor for drapery, but they are noisy and I think are controlled through an appliance module which could be Z-Wave. This would be a very bulky solution though.

If you have Silhouette shades depending on how old they are and what tube was used, they could be retrofitted with tubular motors fairly easily. The motors wouldn’t be Z-Wave, but Somfy RTS and you would use an interface between Vera and RTS, either a ZRTSI, or an URTSI, or a single channel RTS interface.
