I have a Lifx bulb that has been working for many years. Occasionally it will stop working in SmartThings, and to fix it I simply cycle the power and the bulb will start working again. It stopped responding this afternoon and I have been unable to get it to work in SmartThings.
I still use the Classic app. The bulb works fine in the Lifx app so it is connected properly. So far I have cycled power on the bulb many times, rebooted my router and ST hub (v1).
I really can’t remember how I set this up - it’s probably been 4-5 years. Initially I had a community developed app IIRC, but I believe ST and Lifx had a (semi) official integration. I see info about that on both Lifx and ST web sites. But the mechanism doesn’t seem to exist anymore when I tried to reconnect the cloud accounts. I found no reference to Lifx in the Classic app. (https://support.smartthings.com/hc/en-us/articles/205956530-How-to-connect-LIFX-light-bulbs).
Any ideas what I can try before contacting support?
