Pollen information for HA with DWD open data

Introduction

This guide will help you to integrate pollen information into Home Assistant using DWD open data. It is especially useful if you have allergies and want to know the pollen count in your area. Pollen

Prerequisites

Configuration

Needed Information

Name Description Where to find
PART_REGION_ID The ID of the region you want to get the pollen information from. DWD Open Data - Search Document for your region and take the ID. Don't use the ones with 0 at the end.

Sensor

sensors.yaml

What to change

Change the PART_REGION_ID to your region ID.

What it does

This will create two types of sensors.

  • The first one is a sensor to parse the json data from the DWD open data and only select the right region.
  • The second one is a template sensor that will create a sensor for each pollen type with the current pollen count for 0-6 for today and attribute for the value of today and tomorrow.

Restart

After adding the sensor to your configuration, restart Home Assistant. You should now have a sensor for the pollen count in your region.

Lovelace

Now you just could use any card to display the information but I recommend using the custom bar card. You can install it though HACS (Frontend) and is called Bar Card.
