I don’t know in what category this question should be. I try here.
I have spot price tariff from my energy company, hour for hour the price is set. Nordpool SE3.
I would like to have a light bulb set ON when the price per kwh is in the lowest 30% for that day.
So I kan see, bulb i lit then it is time to start washing machine and EV charger.
Anyone looked at something like that?
