OK, I looked at the manual.
It’s a very cool device, and I like that it does double-click, but I don’t think it’s going to work with SmartThings at all.
You could probably set it up for direct association so that pressing a button on this device would cause some other Z wave devices in the same room to go on or off. But you won’t be able to control any zigbee devices or devices more than one hop away or change modes or run routines. and SmartThings will not know what the switch did, so the status in your mobile app will be out of sync with what is actually happening in your home.
Again, no problem in getting one and trying it as long as you get it from a place with a good return policy. But I think you’re going to run into the same stuff that the people who tried the Leviton multibutton controllers ran into. SmartThings just does not support the Z-wave command classes that this device requires.
But I’d be delighted to be wrong on this so if anyone has a different experience, let us know.
