It has been years since I setup my LIFX bulbs with Hubitat. But for the last 3 months they haven't been working. I looked at both the Apps Code: LIFX Master and the Drivers Code: LIFX Color, but there is not webpage given in the comments, so I really don't know where I got these from.
I am guessing there is probably a new version, but does anyone know where to find them. Or is LIFX just no longer supported
In Hubitat, click on Apps Code - use the New App button and paste in the code. Click Save
Then open Apps in Hubitat, click New User App and select Hubitat Package Manager
It should be fairly straightforward from there on in - I think it offers you the option of matching up with existing apps and drivers. That may not work if your LIFX drivers are quite old though.
