Energy Price Forecast
Heat and charge when electricity is cheapest or the grid is greenest.
Plan flexible electricity use before all official day-ahead prices are available. Energy Price Forecast combines current electricity prices and grid CO2 with forecasts, then turns them into clear Homey Flow signals for EVs, heat pumps, boilers, batteries and other flexible loads. Choose the cheapest individual hours in a fixed planning block, a continuous price or CO2 window, or a weekend charging plan. My tariff calculates your own price as market price × factor + surcharge per kWh. Prices can also be sent to HomeFlux EMS through a PBTH-compatible Flow.
Without an API key, the app provides up to 48 hours of planning and a free Saturday-to-Monday weekend mode. An optional Energy Price Forecast Pro key extends planning to up to 120 hours and can start the weekend on Friday. Forecasts and estimated retail prices can differ from final prices; the app always shows the data source, effective horizon and freshness status. Available in English, Dutch, German, Swedish, Norwegian and Danish.
