It has nothing to do with Kodi 18, you have something messed up. Your lat/lon is wrong Can you please post the output of this:

And this affects the operation of Yeelight for KODI?

EDIT:
So, at least I stepped forward, for another reason I gave back LibreElec 8.2.2.3 for S912 Amlogic. After installing the add-in, and either version 4.2 or 4.21 immediately reports an error, the same thing after rebooting KODI. I do not know how, but after one setting, Yeelight worked at the startup / shutdown of the movie, after restarting KODI no longer, it will only help uninstall the add-on, then re-install the add-on, find Yeelight, and then perhaps light will go at least at the start of the movie.

 Hold on, this is os independent and kodi version independent error, due to your location... My addon needs your location, in order to find the sunset/sunrise times, and seems your location is 49 without decimal point, and that crashes the addon. We'll fix that, just patience
