Dynamic time trigger starting at random intervals

[msnapka]

Hi, thanks for all the good work around the project.

I have set up a notification containing the rank of the current hour whenever my automation starts the boiler based on the dynamic trigger. I am using 2,5 hour interval.

Sometimes the boiler is started even in the 22nd cheapest hour...which is a bit useless and counter-productive as it's actually doing quite the opposite of what it should be doing :)

I think the problems occur whenever:

1. negative prices appear (imho even for the following day)
2. Home Assistant is restarted

I will gather more data and add it here, but i had to already write something because the note is on my desk already for longer than a few months and i need to stop procrastinating... O:-)

I am using the prices for Austria.

Thanks.

Marek
