Home Assistant: Pollen Information EU
Hello, dear fellow pollen sufferers! 
Tired of sneezing your way through spring? Now you can track Europe’s pollen levels without turning your sofa into a tissue graveyard:
- 14 European countries supported (Austria → United Kingdom)
- Per-allergen sensors (birch, grass, ragweed…)*
- Air-quality metrics: ozone (O₃), PM₂.₅/PM₁₀, NO₂, SO₂, temperature & more*
- Multi-day forecast to plan your antihistamine doses
- Auto-updates every 8 hours—because pollen never sleeps
(Sensor availability varies by country.)
Pair it with the pollenprognos-card for a sneeze-proof Lovelace UI:
https://github.com/krissen/pollenprognos-card
Note, you need v2.2.0 of the card for compatibility with the integration! This version is still in pre-release. Still testing to make sure I’m not interrupting the current users, of other integrations, before I release this one. 
So try it out and let me know!
