I don't have one, but your post got me interested in looking, as I am currently getting ready to add some smart switches. The price of these are great, your adding a motion sensor for just a few dollars more then a normal smart switch.

Anyways back to your question, I found this review on the dimmer version of the switch

So, it works. Well, stand alone it works fine. Wink does not fully support it. So you get a phantom sensor that you can't control in the app and you get two switches (both do the same thing) in the app. They are aware of the need to upgrade their app. The tech was surprised since they support the Zwave switch and dimmers from GE without a problem. I was too. So, it works, I am keeping it, but with Wink, it's a bit winky. I replaced a sensor and non-dimmer switch with this. I like it
