pollenprognos-card

A Lovelace card that shows pollen forecasts from several integrations. The card supports Home Assistant's visual editor and works with six adapters:

• Pollenprognos
• DWD Pollenflug
• Polleninformation EU
• SILAM Pollen Allergy Sensor
• Kleenex Pollen Radar
• Pollen.lu

Two card instances combined, both using integration `polleninformation`. The top card shows `allergy_risk` in mode `daily`.	Three card instances combined, all using integration `silam_pollen`. The top-most card uses mode `minimal`. The middle card `twice_daily`, and the bottom card `hourly`.

Requirements

Install one of the supported integrations above. The card auto-detects which adapter to use based on your sensors.

Features

• Multi-Integration Support: Works with 6 different pollen data sources (Pollenprognos, DWD Pollenflug, Polleninformation EU, SILAM, Kleenex Pollen Radar, Pollen.lu)
• Auto-Detection: Automatically detects which integration to use based on your available sensors
• Visual Editor: Full Home Assistant UI configuration support - no manual YAML editing required
• Scalable SVG Icons: 24+ allergen icons rendered as lightweight, customizable SVG graphics
• Multiple Display Modes: Support for minimal, daily, hourly, and twice-daily forecast layouts
• Full Localization: Dynamic language support with 13 translations following Home Assistant's language setting
• Extensive Customization: Configure colors, layouts, text size, sorting, and display options through the visual editor
• HACS Integration: Official HACS repository with automatic updates and easy installation

Installation

Add https://github.com/krissen/pollenprognos-card as a custom repository in HACS and install the card. Reload your browser cache after installation.
