# DWD Pollenflug Binding
|
|
|
|
The "Deutsche Wetterdienst" (DWD) reports the current pollen count index for Germany on a daily base and a forecast for tomorrow and the day after tomorrow.
|
|
This binding allows you to retrieve this data for your region or partregion.
|
|
You can find a map of the data [here](https://isabel.dwd.de/DE/leistungen/gefahrenindizespollen/gefahrenindexpollen.html)
|
|
|
|
## Supported Things
|
|
|
|
This binding supports a bridge thing (`bridge`), which polls the dataset for Germany in an adjustable interval.
|
|
And it supports a region thing (`region`), representing the data for all pollen types of a region or partregion.
|
|
|
|
## Discovery
|
|
|
|
This binding adds a default `bridge` thing to the Inbox.
|
|
This can be used for `region` things you may add manually.
|
|
|
|
