DWD Pollenflug

This component adds pollen forecasts from Deutscher Wetterdienst (DWD) to Home Assistant.

The DWD provides forecasts for 27 regions in Germany. The data will be updated daily (currently at 11am) and the forecasts include the data for today and tomorrow (and the day after tomorrow on Friday).

A forecast is provided for the following grass and tree pollen:

• Alder (Erle)
• Ambrosia (Ambrosia)
• Ash (Esche)
• Birch (Birke)
• Hazel (Hasel)
• Grass (Gräser)
• Mugwort (Beifuss)
• Rye (Roggen)

This component fetches data every hour from DWD (although the data is updated only once per day).

If you like this component, please give it a star on github.

Installation

1. Ensure that HACS is installed.

2. Install DWD Pollenflug integration via HACS.

3. Add DWD Pollenflug integration to Home Assistant (one per region):

   

In case you would like to install manually:

1. Copy the folder custom_components/dwd_pollenflug to custom_components in your Home Assistant config folder.

2. Add DWD Pollenflug integration to Home Assistant (one per region):

   

One instance of DWD Pollenflug covers one region. If you want to get the data from multiple regions, just add multiple instance of the DWD Pollenflug integration.

Sensors

This integration provides one sensor per pollen type. The sensor is named according to the pollen type.

Sensor State

The sensor state represents an index of the pollen count. DWD is using the following index range:

Index	Description (in German)
0	keine Belastung
0.5	keine bis geringe Belastung
1	geringe Belastung
1.5	geringe bis mittlere Belastung
2	mittlere Belastung
2.5	mittlere bis hohe Belastung
3	hohe Belastung

Sensor Attributes

Each sensor provides the following attributes (not including default attributes):

Attribute	Example	Description
state_tomorrow	1	Forecast for tomorrow.
state_in_2_days	1	Forecast for the day after tomorrow.
state_today_desc	geringe Belastung	Human readable description of the forecast for today [in German].
state_tomorrow_desc	geringe Belastung	Human readable description of the forecast for tomorrow [in German].
state_in_2_days_desc	geringe Belastung	Human readable description of the forecast for the day after tomorrow [in German].
last_update	2021-09-28T11:00:00+02:00	Timestamp representing the last update of the data by DWD.
next_update	2021-09-29T11:00:00+02:00	Timestamp representing the next update of the data by DWD.

Examples

A minimalistic example in combination with Lovelace-Mushroom-Cards can look like this:

To configure:

• Edit your dashboard
• Add a new Mushroom-Template-Card and copy/paste:

square: true

You can also add the description / forecast:

Code:

square: true
type: grid
columns: 2
cards:
  - type: custom:mushroom-template-card
    entity: sensor.pollenflug_graeser_124
    primary: Gras
    secondary: >-
      Today: {{ state_attr('sensor.pollenflug_graeser_124', 'state_today_desc') }}

      Tomorrow: {{ state_attr('sensor.pollenflug_graeser_124', 'state_tomorrow_desc') }}
    icon: mdi:grass
    layout: vertical
    icon_color: |-
      {% if states(config.entity) | int <= 1 %}
        green
      {% elif states(config.entity) | int <= 2 %}
        orange
      {% elif states(config.entity) | int <= 3 %}
        red
      {% endif %}
    tap_action:
      action: more-info

Use of auto-entities:

Code:

type: custom:auto-entities
card:
  type: grid
  columns: 2
  square: false
card_param: cards
filter:
  include:
    - name: Pollenflug*
      state: '>0'
      options:
        type: custom:mushroom-template-card
        primary: '{{state_attr(''this.entity_id'', ''friendly_name'')}}'
        secondary: morgen {{state_attr('this.entity_id', 'state_tomorrow_desc')}}
        icon: '{{state_attr(''this.entity_id'', ''icon'')}}'
        layout: horizontal
        icon_color: |-
          {% if states(config.entity) | float <= 1 %}
            green
          {% elif states(config.entity) | float <= 2 %}
            orange
          {% else %}
            red
          {% endif %}
        tap_action:
          action: more-info
        hold_action:
          action: none
        double_tap_action:
          action: none
        multiline_secondary: true
  exclude: []
