I keep looking for z-wave add on control for existing blinds but the choice here is close to zero. The nearest i have seen was a solar powered motor unit which fastened to the side of the window and could raise and lower roman blinds but this was only bluetooth controlled and not actually available yet.

Zwavemotors. Looked on your web site but cant see details of what is actually available and ideas of price.
Actually it’s gone past all it’s extended goals and they had to come up with a new one. It will now support some form of wire control that would allow it to interface with HA controllers. I’ll find out if and when they start shipping as I ordered 2.
