Same issue for me, on Core Beta 2022.5.0b0.
Traced back to this breaking change made to the core for the beta: home-assistant/core#69643

Is there any plan to transition to the built-in event helpers? Sounds like a small change but I'm not a programmer:( "in most cases, a one-line drop-in replacement"

https://developers.home-assistant.io/blog/2022/04/20/saying-goodbye-to-event_time_changed/

[Hellowlol]

I haven't had time to investigate it. But I highly doubt we can just drop in and replace it, as I have modified the code to support other timezones.

[Klangen82]

I believe you when you say that, as I said not a programmer:/ It's just that the integration will not work when they release 2022-05 version. You have UTC time changes so I guess this should work with times zones, but again that do I know. Please let me know if there is anything I can do or help and I will try my best.

Anybody want to test #145 ? This should work with the latest dev version

Maybe I did something wrong, but I couldn't get it to work.

It would be easier for me to test this if it showed up as a beta version in HACS.

I manually copied the 4 changed files from 0.0.6 and got the same error as Skeletorjus.

[Klangen82]

Same here, I tested with HA version 2022.5.0b7.

[KennethSeiero]

Same here, this is no longer just the beta version. I'm on the official branch, and my nordpool just stopped working after 2022.5.0 update

[Hellowlol]

That's strange, that typing signature is copied directly from homeassistant and works fine in my dev docker. What python version are you running?

[Klangen82]

Thanks @Hellowlol for fixing this :)
