Tankerkönig Binding

The binding uses the Tankerkönig API (https://www.tankerkoenig.de) for collecting gas price data of german gas stations. Special thanks to the creators of Tankerkönig for providing an easy way to get data from the MTS-K (Markttransparenzstelle für Kraftstoffe).

Tankerkönig is providing this service for free, however they request to prevent overloading of their server by reducing the number of web-requests. This binding handles those requests (minimum Refresh Interval is 10 minutes, a webserver does handle maximum of 10 stations. The data will be updated for each Station individually after the initialization and after each Refresh Interval for all (open) stations (Note: changing the Webservice will cause the Refresh Interval to restart). Additionally one may select the mode Opening-Times in which only those Stations get polled which are actually open.


In order to use this binding one needs to prepare:

-a personal API-Key

Demand free Tankerkönig API key from: https://creativecommons.tankerkoenig.de/ Select the tab “API-Key”.

-LocationIDs of the selected gas stations

Search for the gas station IDs here: https://creativecommons.tankerkoenig.de/configurator/index.html Drag the red marker on the map to the rough location of desired gas stations. Select the gas stations and click “Tankstellen übernehmen” on the right. This will download a file holding the location IDs. For example: a7cdd9cf-b467-4aac-8eab-d662f082511e

Supported Things

This binding supports:

-Webservice (bridge)

-Station (thing)


The binding provides no discovery. The desired Webservice and Stations must be configured manually or via a things file.

Binding configuration

The binding has no configuration options itself, all configuration is done at ‘Bridge’ and ‘Things’ level.

Thing configuration

The Webservice (bridge) needs to be configured with the personal API-Key, the desired Refresh Interval (the time interval between price-updates, default 60 minutes, minimum 10 minutes) and the Opening-Times mode selection (in this mode price-updates are only requested from stations that are actually open). A single Webservice can handle up to 10 Stations.

Each Station needs to be configured with a LocationID and the Webservice to which it is linked.


The binding introduces the following channels:

Channel ID Channel Description Supported item type Advanced
e10 price of e10 Number False
e5 price of e5 Number False
diesel price of diesel Number False
