# 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 (opens new window)

# 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.

# Thing Configuration

# Bridge

Parameter Default Required Description
refresh 30 no Define the interval for polling the data from DWD in minutes. Minimum is 15 minutes.

# Region

Parameter Default Required Description
regionID - yes The id of the region. The available options are in the table below.

# Manual region or partregion selection

The region ID is the partregion_id or if there is no partregion the region_id from this json (opens new window) of DWD. You can refer to the following table.

For each of the eight pollen types reported by DWD the region thing has three channels for today, tomorrow and the day after tomorrow.
