First off thank you for your support on this project!

I have a homeassistant installation running in docker using python-kasa for integration with one HS103 switch with firmware 1.0.3. After upgrading homeassistant from 2023.10 to 2023.11 which included an upgrade of python-kasa from 0.5.3 to 0.5.4 I am no longer able to discover or directly connect to my switch. The homeassistant upgrade was purely a version bump and the integration code had no changes, so I expect the regression is in the python-kasa library.

I'm technically adept so would be willing to help investigate what caused the regression, either through homeassistant or by running the cli in a docker container. The issue may be related to this feature request: #517
