Thanks but I am not using Nefit Easy. How would I determine which of my integrations (presumably HACS) would be using it? Search the repositories one by one but for what??

Which one of these do you think I should focus on?

Did you resolve this? I have same issue, can’t figure out which custom component may be generating the warning.

I searched all of my add-ons and the only one with the path /usr/local/lib/python3.9/site-packages/slixmpp/stringprep.pyt was Supervisor. So for the hell of, I deleted my Harmony integration as I had found discussions about it triggering the warning. After removing it, the warning message stopped. Apparently the warning in built into the underlying python3.9 library which HA has no control over…

Right on. I deleted my Harmony integration long ago - maybe a ghost reference / leftover file somewhere in my environment. Will need to find time to hunt that snipe.
