About

Polleninformation EU is an integration that creates pollen and allergy risk sensors from the Austrian Pollen Information Service. It covers countries across Europe, including Austria, Germany, France, Sweden and Spain, and adds an individual sensor for each allergen detected at the chosen location. Each sensor shows the current pollen level as text, with the numeric value and a multi-day forecast in its attributes. Two allergy risk sensors report risk by day and by hour, with the API's 0 to 10 value scaled to the same 0 to 4 range as the allergen sensors and the raw value kept as an attribute. Data comes from the vendor's cloud and needs a personal API key. The update interval can be set in the options, and an option lets the risk sensors take the integration language for their names. Setup is done in the UI by choosing a country, a location on the map and a language.
