Terry,
When we were exploring the different Z-Wave device options, we had window blinds on the list as an option for its specific page and classification in the system. But we did not see that this was something that being supported well by manufacturers of Zwave devices, so we decided to not expand on it. I am interested in hearing more feedback. We can look at expanding the capibilites of the system around Zwave Window Coverings, if this is a viable need.
Again, early research appeared that it was not being supported well, but it is possible that has changed. I will take a look at the link you provided.
Thanks,
Mike
