HomeAssistant

I use the following rest and template sensors in HA:

sensor:
  - platform: rest
    scan_interval: 3600
    name: "DWD Pollenbelastung"
    resource: https://opendata.dwd.de/climate_environment/health/alerts/s31fg.json
    json_attributes_path: "$..content[?(@.partregion_id==XXX)].Pollen"
    json_attributes:
      #- Erle

      - Graeser
      #- Roggen
    value_template: "{{ value_json.last_update }}"
  - platform: template
    sensors:

Notes

• As this card is mainly for the DWD pollen sensor, that is based in Germany and shows only german data, the only available language is "German". If you want another language added, please leave a message in the support thread.
