Seems the plugin stopped working after HAOS 2022.3.0 udpate. The entity becomes unavailable and cannot pass configuration check: "Platform error media_player.kef_connector - Requirements for kef_connector not found: ['pykefcontrol==0.5']."
Thanks @tjxism, I just release version 0.5.5 which resolves the issue.
Update to the last version and you should be good. Feel free to reopen the issue if it is not the case !
