Hey there @heythisisnate, mind taking a look at this issue as its been labeled with a integration (konnected) you are listed as a codeowner for? Thanks!

[davidbb]

I ran into this issue as well. Resolved it the same way as @TazUk with the manual install of netdisco. I think this could be resolved by adding netdisco to the install requirements of the konnected integration.

[heythisisnate]

This is possibly related to #27284 and #29020
netdisco and discovery are optional dependencies for Konnected (not needed if you manually specify IP address and port).

I'm not sure exactly how to address this right now without explicitly making those libraries a strict dependency.

I have netdisco installed, but still get same error: - Package konnected setup failed. Component konnected No module named 'netdisco'. Any hints how to solve this?

This should be fixed by #30894 as discovery now occurs via ssdp
