Got 2 Lifx bulbs, set them up and worked for a few hours. Was able to change colours and do everything, including integrate with Smart Things. After some time, I find I can longer control with the Lifx app (and a question mark appears in the Smart Things app against the bulbs). I don’t want to have to set it up all over again., which I’m not sure will always work.
The router settings are all fine, got the bulbs on the 2.4 Ghz band, security setting is fine, and channel is 11.
