This is a good round up of what’s currently available as far as smart films/glass ( check the comments as well) but I haven’t looked at the individual ones to see if it would be possible to make any of them compatible with SmartThings. None of them are Z wave, though, it’s going to be a cloud to cloud integration if it is possible.
updated to add @AnotherUser makes a very good point below: if just turning the power on/off will change the film/glass the way you want it, then that’s easy to integrate with SmartThings. If it’s a plug-in, plug it into a networked pocket socket. If it gets hard wired, use an in wall microswitch or relay.
