@bunjamin1982 I had the same error - I upgraded HA itself to latest (2024.5.3) and it's fixed it, maybe give that a spin?

[BottlecapDave]

Ah looks like the deprecation warning I was fixing had it's solution only added in 2023.5. I'll update the minimum version. I'm sorry that you encountered this. As @c235tgfer mentioned you can either upgrade HA or revert to an older version of the integration.

[BottlecapDave]

I've re-released v11.0.0 with the minimum HA version set to 2024.5.0.

Thank you all - I can confirm upgrading to a later HA version has fixed the issue
