Just to note, the bulbs do not support S2
Yes, trying to get the bulbs working with the switch at S2 level added some time to the overall troubleshooting process for me.
I’d suggest updating the spec sheet as it currently indicated that S2 Encryption is supported which sent me down a bit of a wild goose chase trying to get that to work properly 
Given the out of the box experience of the switch and bulb with Hubitat doesn’t work as expected, perhaps worth recording a short video to walk people through the setup so they don’t hit the same issues I encountered? Would be good to add to the excellent library of videos that have already been put together on other topics.
