Hello,
I discovered in Home Assistant that my T310 (connected via H100) was reported as unavailable and upon investigating I found that python-kasa was throwing the attached error.
I ran the following command from inside the Home Assistant v2025.2.1 docker container kasa --username <username> --password <password> --host <host> --debug &> dump.txt.
python-kasa-v0.10.1-dump.txt
