Weather reports like temperature, humidity and air pollution, based on data from local weather stations used in Luftdaten (German Webseite: http://luftdaten.info/ , English Webseite: https://en.airbg.info/ ) project. The skill uses the data collected from those weather stations and can be setup to use data from a specific station. You can use the data from your own weather station (if you have one) or from some other weather station close to you. The only thing you need is to know the weather station Chip ID and to set it up by saying "set Chip ID 581294"
