I am getting the same log after HA restart, I'm still on 2024.12.5 and latest version of freeathome.

The problem originates in Slixmpp. Other Homeassistant integrations have the same warning. https://codeberg.org/poezio/slixmpp/issues/3582 contains a solution, now waiting for a new release of Slixmpp.
