As far as I know, the only model which is currently available is the Bluetooth version, and that one will not work with SmartThings.
The V2 version which worked with SmartThings was the Z wave one. I would expect the V3 zwave version to also work, but again, as far as I know that model has not yet been released. Also, it will have to be on the same frequency as your SmartThings hub, as the UK and US frequencies are different.
The V3 is intended to be released in 4 models:
US zwave and bluetooth
UK zwave and bluetooth
So which exact model did you get? And which version of the SmartThings hub do you have?
