# Supported Things

# Station selection

Stations can be selected with an Universally Unique Identifier (uuid). It's automatically added by the Discovery. Configure a station manually using list of all available stations (opens new window) or stations.json (opens new window) and choose the uuid of your desired measurement station.

# Warning Levels

Each station has specific warning levels

  • Warning Levels 1 (lowest) to 3 (highest)
  • Flooding Levels

Unfortunately these levels cannot be queried automatically. Please select your federal state (opens new window) and check if which levels they provide. The picture shows the levels of measurement station Marburg of federal state Hesse (opens new window)

If you cannot evaluate warning or flooding levels leave the parameter empty.
