# Deutsche Bahn Binding
![](/logos/deutschebahn.png)
The Deutsche Bahn Binding provides the latest timetable information for all trains that arrive or depart at a specific train station, including live information for delays and changes in timetable. The information are requested from the timetable api of Deutsche Bahn developer portal, so you'll need a (free) developer account to use this binding.
# Supported Things
- timetable The timetable bridge connects to the timetable api and provides information for the next trains that will arrive or depart at the configured station.
- train The train thing represents one trains within the configured timetable. This may be an arrival or a departure.
# Thing Configuration
# Generate Access-Key for timetable API
To configure a timetable you first need to register at Deutsche Bahn developer portal and register for timetable API to get an access key.
- Go to Deutsche Bahn Developer (opens new window)
- Register new account or login with an existing one
- If no application is configured yet (check Tab "Meine Anwendungen") create a new application. Only the name is required, any other fields can be left blank.
- Go to APIs - Timetables v1 (may be displayed on second page)
- Choose your previously created application and hit "Abonnieren"
- In confirmation-dialog choose "Wechsel zu meine Abonnements"
- Create an access key for the production environment by hitting "Schlüssel Erstellen"
- Copy the "Zugangstoken". This is required to access the api from openHAB.
# Determine the EVA-No of your station
For the selection of the station within openHAB you need the eva no. of the station. You can look up the number within the csv file available at Haltestellendaten (opens new window).
# Configure timetable bridge
With access key for developer portal and eva no. of your station you're ready to configure a timetable (bridge) for this station. In addition you can configure if only arrivals, only departures or all trains should be contained within the timetable.
timetable parameters:
Property | Default | Required | Description |
---|---|---|---|
accessToken | Yes | The access token for the timetable api within the developer portal of Deutsche Bahn. | |
evaNo | Yes | The eva nr. of the train station for which the timetable will be requested. | |
trainFilter | Yes | Selects the trains that will be displayed in the timetable. Either only arrivals, only departures or all trains can be displayed. | |
additionalFilter | No | Specifies additional filters for trains, that should be displayed within the timetable. |
** Additional filter ** If you only want to display certain trains within your timetable, you can specify an additional filter. This will be evaluated when loading trains, and only trains that matches the given filter will be contained within the timetable.
To specify an advanced filter you can
- specify a filter for the value of a given channel. Therefore you must specify the channel name (with channel group) and specify a compare value like this:
departure#line="RE60"
this will select all trains with line RE60 - use regular expressions for expected channel values, for example:
departure#line="RE.*"
, this will match all lines starting with "RE". - combine multiple statements as "and" conjunction by using
&
. If used, both parts must match, for example:departure#line="RE60" & trip#category="WFB"
- combine multiple statements as "or" disjunction by using
|
. If used, one of the parts must match, for example:departure#line="RE60" | departure#line="RE60"
- use brackets to build more complex queries like
trip#category="RE" AND (departure#line="17" OR departure#line="57")
If a channel has multiple values, like the channels arrival#planned-path
and departure#planned-path
have a list of stations,
only one of the values must match the given expression. So you can specify a filter like departure#planned-path="Hannover Hbf"
to easily display only trains that will go to Hannover Hbf.
If the filtered value is not present for a train, for example if you filter a departure attribute but train ends at the selected station, the filter will not match.
# Configuring the trains
Once you've created the timetable you can add train-things that represent the trains within this timetable. Each train represents one position within the timetable. For example: If you configure a train with position 1 this will be the next train that arrives / departs at the given station. Position 2 will be the second one, and so on. If you want to show the next 4 trains for a station, create 4 things with positions 1 to 4.
Attention: The timetable api only provides data for the next 18 hours. If the timetable contains less train entries than you've created train things, the channels of these trains will be undefined.
train parameters:
Property | Default | Required | Description |
---|---|---|---|
position | Yes | The position of the train within the timetable. |
# Channels
Each train has a set of channels, that provides access to any information served by the timetable API. A detailed description of the values and their meaning can be found within the Timetables V1 API Description (opens new window). The information are grouped into three channel-groups: The first channel group (trip) contains all information for the trip of the train, for example the category (like ICE, RE, S). The second and third channel group contains information about the the arrival and the departure of the train at the given station. Both of the groups may provide an 'UNDEF' channel value, when the train does not arrive / depart at this station (due it starts or ends at the given station). If you have configured your timetable to contain only departures (with property trainFilter) the departure channel values will always be defined and if you have selected only arrivals the arrival channel values will always be defined. Channels will have a 'NULL' channel value, when the corresponding attribute is not set.
Basically most information are available as planned and changed value. This allows to easy display changed values (for example the delay or changed platform).
Channels for trip information
channel | type | description |
