Swiss Pollen integration for Home Assistant

A Home Assistant integration that provides pollen data for Switzerland from MeteoSchweiz. Data integration is done via swiss-pollen.

This integration is not officially developed, supported or endorsed by MeteoSchweiz.

Features

• Provides pollen concentration data for various plant types in Switzerland
• Data is sourced from MeteoSchweiz
• Supports multiple measurement stations across Switzerland
• Provides both numeric values (No/m³) and categorical levels (None, Low, Medium, Strong, Very Strong)

Installation

HACS (recommended)

You can install this component through HACS to easily receive updates. Once HACS is installed, click this link:

Manual Installation

1. Download the latest release from the releases page
2. Unpack the release and copy the custom_components/swiss_pollen directory into your Home Assistant's custom_components directory
3. Restart Home Assistant

Configuration

1. Go to Settings > Devices & Services
2. Click "Add Integration"
3. Search for "Swiss Pollen"
4. Follow the configuration flow to set up a service for a specific plant:
   • Select a plant of interest
   • Select one or more measurement stations to get sensors for these stations
5. You can repeat step 4) to set up multiple services, one for each plant you are interested in

Available Sensors

For each selected plant, the integration creates the following sensors:

1. Numeric concentration (sensor/location): Shows the pollen concentration in No/m³ (number per cubic meter)

   • Icon: mdi:flower-pollen

2. Level (sensor/location): Shows the categorical level of pollen concentration

   • Possible values: None, Low, Medium, Strong, Very Strong
   • Icon: mdi:flag

3. Plant season (binary sensor): Shows whether the plant has pollen season or not. The sensor is 'on' if at least one station in Switzerland reports a value greater than zero).

4. Backend version (diagnostic sensor): Shows the version of the backend providing the pollen data.
