A fork of the great work of leahoswald's work on a card, but not useable with HACS. Here is the custom card, you could use.

A Lovelace custom card for https://github.com/mampfes/hacs_dwd_pollenflug in Home Assistant based on the great work of https://github.com/isabellaalstrom/, https://github.com/isabellaalstrom/lovelace-pollenprognos-card and https://github.com/TekniskSupport.

Not now, maybe future:The easiest way to install it is through HACS (Home Assistant Community Store), search for Pollenprognose Card Ottes in the Frontend section and install it (or another fork?).

For fow: Install this repo as Custom repo and search for Pollen on the frontent

If you are NOT using HACS, you may download -ottes.js plus the images folder and put it into homeassistant_config_dir/www/community/lovelace-dwd-pollenprognose-card-ottes/ directory.

Pick the allergens you want to display.
