I recently bought 3 of the LZW42 color bulbs. I added them and used the default DTH they paired with (“RGBW Light”). I assumed this would let them run locally. Later on, I noticed a SmartLighting automation I added one of the bulbs to had moved to the cloud. That’s when I noticed the bulb itself was in the cloud.
Again, this is not using the DTH from github in InovelliUSA/SmartThingsInovelli
