About

ČHMÚ Weather brings current outdoor weather data from Czech Hydrometeorological Institute stations into Home Assistant. It adds sensors for temperature, humidity, pressure, precipitation, wind speed and wind direction, limited to what the chosen station measures, plus a text weather description. A weather entity provides a per-station forecast taken from the ALADIN 1 km model. The station nearest to the Home location is pre-selected during setup, which is done in the UI. Each 10-minute reading is also kept as hourly statistics, so history can be shown in a statistics graph card, though precipitation is not included. It relies on cloud data, is aimed mainly at Czech users because of where the stations are, and is installed through the Marketplace.
