You probably need to refresh the Kodi repository via the slide menu on the left in the addons section.
Also make sure you have 'Wait for network' enabled for at least 30 seconds (Pi hardware is slow).
As mentioned above in the UPDATE line I had to download the kodinerd repository in this version - which I did not had to in the previous version for my Pi 3. I had no network problem, Pi Zero Wifi connection is instantly there cause the weather was updated.
It was a bit tricky to get behind cause in the past I always had to select weather service and city instead of download a repository.
The only question: has that been a change between 8.0 and 8.2 or is it a difference between the Pi 2 / 3 and Pi Zero built.
THANKS A LOT FOR YOUR QUICK + PROFOUND ANSWER !
