I did a little packet sniffing on this device. It pairs to the bulb using ZLL Commissioning (touchlink) and sends all commands using it’s unique group number. It does not seem to support any endpoint binding, unfortunately. It would respond with success to a bind command, but it wouldn’t send anything other than a group multicast when a button is pushed.
I don’t think there’s any way right now to configure SmartThings to accept a group multicast packet.
