# Pollen DK (Astma-Allergi Danmark)

> Pollen DK (Astma-Allergi Danmark) is a Marketplace integration for Home Assistant. It has 77 installs sharing analytics, needs the vendor's cloud and was last updated October 27, 2026.

Pollen DK (Astma-Allergi Danmark) is an integration that brings live Danish pollen and spore data into Home Assistant. It reads the JSON feed of Astma-Allergi Danmark through the vendor's cloud and covers two measurement stations, København for eastern Denmark and Viborg for western Denmark. Each of the eight pollen and spore types gets a count sensor with a severity attribute, and each region also gets an overall severity sensor showing the worst level across all types. A five-day forecast is included, with daily counts per allergen and a worst-severity summary for each day. The integration also ships a custom dashboard card that shows the forecast as a grid of severity dots, with a detail popup for each row and Danish and English labels. Setup is done in the UI by choosing a region.
