Hi there!
First of all, thank you for this wonderful project!
I discovered it a while ago while searching for an ambilight-like setup with my kodi media center and the living room yeelights.
Since the current kodi addon is fairly old, I've updated it and made a PR to the official repository, but it seems that there's nobody there anymore.
Do you confirm that there's no interest/willpower to maintain the add-on anymore? If so, and if you don't mint, I will directly submit a PR to the official kodi add-on repository in order to make it available to as many people as possible.
Thanks for the attention, have a wonderful day!
