DMI pollen integration for Home Assistant

This integration retrieves the pollen data for Danmarks Meteorologiske Institut (Denmark's governmental Weather provider).

[!] This implementation uses an unofficial API and it may change in the future

DMI is in the works of making all there data free via DMI open data project. This is not done yet.

Installation

1. Download zip file and extrat it into the custom_components folder in your config folder. If it does not exist, then create it.
2. Add dmi_pollenin your configuration.yaml file. See below:

sensor:
  - platform: dmi_pollen

3. Restart your HA installation.
4. Now you should see two different sensors. sensor.dmi_pollen_kobenhaven and sensor.dmi_pollen_viborg.

Note: There is only two measurement stations in denmark. One in Københaven(Copenhagen) and one in Viborg.
