Seems like a breaking change in HA, needs investigation.

[epaulsen]

Not able to reproduce this in my development environment, energytariff loads without any issues after upgrading to 2023.6.0.
I have yet to upgrade my production environment to 2023.6.x, will try that later this week.

[ruant]

Yeah, not sure what happened here. Might just be a single error that happened to me. Sorry.

[ruant]

Not sure what I've done. But got this error again :/

Getting the same issue here, after newly starting to use energy tariff. HA 2023.7.2.

@epaulsen Any idea what could cause this?

[epaulsen]

Not sure. I am on vacation until sunday, so not able to investigate until then.

Might be some breaking changes in entity setup in the latest HA releases, I haven't updated HA since may.

[epaulsen]

Finally able to reproduce this in my setup. Race condition during startup. Should have a fix within an hour or so.

[epaulsen]

Fixed in release 0.2.3.

Sorry that it took so long to hunt down this bug!
