About

ČEZ HDO is a Marketplace integration that shows the ČEZ low and high tariff (HDO) schedule in Home Assistant. It reads the data from the vendor's cloud and is set up in the UI by entering an EAN number, a code from a CAPTCHA image and the HDO signal to follow. Binary sensors report whether the low tariff or the high tariff is active and whether the data is valid. Sensors give the start, end and remaining time of each tariff period, the current price, the schedule, the raw data, and how old the data is and how long it stays valid. Prices for the low and high tariff can be entered in CZK per kWh, and automatic data refresh can be switched on. Actions refresh the data, list available signals, reload the frontend card and set tariff prices, and a diagnostics download is available for bug reports.
