I also bought a kit.
The bulb works fine with the "Generic Zigbee CT Bulb (dev)" driver.
The remote does pair, but I could not get any response out of it - having tried most of the Zigbee button controllers.
Having said that, there is another remote that looks exactly like it - the Aurora AOne Smart Remote. That supposedly works with Smartthings UK (see post #156), and the Ecosmart remote is supposed to work with Smartthings here in US.
