# PegelOnline Binding
|
||
|
|
|
||
|
|
Binding to observe water level from german rivers.
|
||
|
|
Data is provided by german **Water-Route and Shipping Agency** [WSV](https://www.pegelonline.wsv.de/).
|
||
|
|
Goal is to monitor actual water levels from rivers nearby your home.
|
||

|
In case of changing water levels the corresponding warning level is lowered or raised.
|
||
|
|
|

## Thing Configuration
|
||
|
|
|
||
|
|
Thing configuration contains 3 sections
|
||
|
|
|
||
|
|
* [Station selection](station_selection)
|
||
|
|
* [Warning Levels of selected station](warning_levels)
|
||
|
|
* [Refresh rate](configuration_parameters)
|
||
|
|
|
||
|
|
### 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](https://pegelonline.wsv.de/gast/pegeltabelle) or [stations.json](https://www.pegelonline.wsv.de/webservices/rest-api/v2/stations.json) and choose the uuid of your desired measurement station.
|
||
|
|
|
||
|
|
### Warning Levels
|
||
|
|
|
||
|
|
<img align="right" src="./doc/Marburg.png" width="450" height="500"/>
|
||
|
|
|
||
|
|
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](https://www.hochwasserzentralen.de/) and check if which levels they provide.
|
||
|
|
The picture shows the levels of [measurement station Marburg of federal state Hesse](https://www.hlnug.de/static/pegel/wiskiweb2/stations/25830056/station.html?v=20210802152952)
|
||
|
|
|
||
|
|
If you cannot evaluate warning or flooding levels leave the parameter empty.
