@Iam Tobe I still need to do some documentation on Yeelight.
Nevertheless, after using the Wizard the Yeelights should work. Sometime you first need to restart hyperion...(for that we have an issue already logged).
As it looks like that the configuration did not work at your end automatically.
Would you mind activating the debug log mode (in the UI System->Log),
plus then start the yeelight wizard and do the config again?
Does the "Identify Light" button works for you? i.e. the respective Yeelight blinks red/blue?
Please share a screenshot of the wizard (see sample below) and the log-output with me, please.
I would like to explore, if it is a coding or documentation issue.
Thanks for your support!
