Hopefully you’ll get a lot of answers.
I did just want to mention that if you find any you like that work with the Logitech Harmony hub, that’s another way to get integration. You can have the harmony control The curtains or blinds in the same way that the remote that comes with them does, but smarthings can talk to harmony. In fact, harmony has an IFTTT channel, so you can also go that way.
This may introduce a little lag, but that’s usually not an issue for window coverings the way it is for lights. People are OK with waiting even 15 or 20 seconds for the curtains to change, where that would typically be unacceptable for lights.
Harmony has a database on their website of everything they work with so you can just look up models there.
