Energy dashboard calculation and tariff derived from schedule helper

Good afternoon (o;

I’ve setup a schedule helper to change electricity tariff, so the correct price is set for low and high tariff.

The high tariff start at 7AM weekdays…and the energy dashboard is updated once every hour:

So what does this mean for the calculation?

Would it take the high tariff when at 7AM it calculates the energy costs for the past hour or the tariff set at 6AM?

thanks in advance
