About

Czech Energy Spot Prices is an integration that provides current Czech electricity and gas spot prices based on OTE. It adds sensors for current, cheapest and most expensive prices, plus binary sensors that flag the cheapest periods and whether data for tomorrow is available. Electricity can be tracked in 60-minute or 15-minute intervals, in EUR or CZK, and in kWh or MWh. Templates can turn the spot price into buy and sell costs that include VAT and distribution fees, and a sensor is only created when its template is entered. The integration can be added several times, for example one instance per commodity or interval, and each is configured separately. It uses a cloud connection, is set up in the UI, and keeps the last downloaded prices across restarts.
