There is probably another process listening on the port, can you a) restart Kodi and try again b) disable addons/services which might use the same ports... Doesn't seem like addon error, more like your local config.

 Indeed, not getting an error in kodi log after uninstalling Addon, restarting kodi and reconfiguring. But there is no response from Yeelight strip when starting a video. Testing it works normally.
