Spot Forecast documentation

Spot Forecast is a Home Assistant integration that forecasts the day-ahead electricity price of the DE-LU, NL, DK1, DK2 or NO2 bidding zone, hour by hour, for the six days after the last published auction result. Per hour it gives an expected price, a peak-risk value (P90) and a low-price value (P10). It runs on open data from Energy-Charts and Open-Meteo, without an account or API key.
