Looks like you're using an old version of the integration?

[richatnort]

Well this is strange, i thought i was on the latest version of the integration before i updated the core and then now i go onto the HACS UI & a new version appeared! Sorry for the panic, user error!

[canton7]

Yep, the version we released the fix in only works on the newer HA: it wasn't backwards compatible.
