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:

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.
