Theoretically it should be possible as anything is. How many turns do you need to set them from full close to full open? just one? If so than a “servo” and a shutter z-wave module should do the think… [url=http://www.ebay.com/itm/390708498593]http://www.ebay.com/itm/390708498593[/url]
This is just a rough sketch off what is necessary … Probably you need a stronger servo with more torque
I think your link is the best bet in price and performance. When I read you first post it was the link I was thinking of, then I saw you had already found it. There might be a few solutions on the market, but they are expensive and probably wouldn’t retrofit to your existing shutters (sold as new shutters). You can play around with where you place the servo maybe, but that method seems like the best option for you.
