About

IRM KMI Weather Belgium is a weather provider that uses data from the Belgian meteorological institute IRM KMI. It adds a weather entity with current conditions and hourly, daily and twice-daily forecasts, plus a camera showing the rain radar. A custom action returns short-term rain forecasts from the radar data, and only precipitation is available there. A binary sensor shows whether a weather warning is active, and a separate sensor gives the start time of the next warning. Further sensors report pollen levels, sunrise and sunset, temperature and wind speed. Data is only available for Belgium and Luxembourg, it comes from the vendor's cloud, and the integration is set up in the UI with a zone, radar style and language.
