Description

This module shows live public transport information in Germany for all stations known to the Deutsche Bahn system. Most public transportation providers in Germany providing information for that system so the coverage should be quite good. The data is provided by the fantastic hafas-client. Even in other european countries this module should work as HAFAS is widely used throughout Europe.

You can very easy adapt the shapes and line colors of your local transport companies. See Providing a custom CSS file.

How it works

After you installed MMM-PublicTransportHafas you just configure it to your needs and that’s it. The only config you really need to set is the stationID property. This determines the station you want to display. Everything else is covered by defaults but can be configured by you anyway. For instance you can enter a time you need to get to the station (timeToStation in config). The module then only shows departures you can reach respecting the set time.

For more information see the Configuration section.

Installation

Just clone the module into your modules directory and install the dependencies:

cd ~/MagicMirror/modules
git clone https://github.com/KristjanESPERANTO/MMM-PublicTransportHafas
cd MMM-PublicTransportHafas
npm ci

Update

Just enter the module's directory, pull the update and install the dependencies:

cd ~/MagicMirror/modules/MMM-PublicTransportHafas
git pull
npm ci

How to get the `stationID`

You need the stationId for the station whose departures should be displayed.

Here's how to find out the stationId:

You have to be in the modules directory (~/MagicMirror/modules/MMM-PublicTransportHafas).
Then run the following command: npm run query.
Enter a station name. It is useful to enter a city name too since the system knows a lot of stations even outside Germany.
The result could contain one or more possible stations with valid IDs.
Use the appropriate ID as stationId in the configuration of the module.

The following example shows a query for "Leipzig, Wilhelm-Leuschner-Platz". This station is included two times in the result. You have to experiment which ID gives the best results.

Enter an address or station name: Leipzig, Wilhelm-Leuschner-Platz

Stops found for 'Leipzig, Wilhelm-Leuschner-Platz':

 > Stop: Leipzig Wilhelm-Leuschner-Platz
   ID: 8012202
   Transport product(s): Regio, S-Bahn, Bus, Tram

 > Stop: Wilhelm-Leuschner-Platz, Leipzig
   ID: 955252
   Transport product(s): Regio, S-Bahn, Bus, Tram

 > Stop: Wilhelm-Leuschner-Platz, Weiterstadt
   ID: 115849
   Transport product(s): Regio, Bus

 > Stop: Wilhelm-Liebknecht-Platz, Leipzig
   ID: 956558
   Transport product(s): Bus, Tram

By default, the module uses the db profile of the hafas-client. In some cases it can be advantageous to use a different profile - e.g. the default profile often does not provide platform information from local transport companies. Here you can find the name of all supported interfaces. Just add the name as a parameter to the command. Like sbb for the profile of Swiss Railways.

npm run query sbb

Configuration

Configuration options

The module is quite configurable. The only option you really have to set is stationID - all other options are optional.

Option Description

hafasProfile

The name of the hafas profile.

Type: string
Example: "insa"
Default value: "db"

Note: In most cases you don't need to change the value. You can find supported profiles and there names here.

Each profile uses its own StationIDs. So if you change the profile, you have to find out the StationID again.

stationID

The ID you want to display departures for.

REQUIRED
Type: string
Example: "8012202"
Default value: none

Note: How to get the ID is described here.

stationName

The name of the station as it should appear on the display.

Type: string
Example: "Wilhelm-Leuschner-Platz"
Default value: none

Note: If you leave this setting, headerPrefix and headerAppendix blank the module will show an empty header.

headerPrefix

The text to be prepended to the stationName.

Type: string
Example: "von" (Will result in “von Wilhelm-Leuschner-Platz” being displayed.)
Default value: ""

Note: A blank between headerPrefix and stationName is automatically inserted.

headerAppendix

The text to be prepended to the stationName.

Type: string
Example: "(Richtung HBF)"
Default value: ""

Note: A blank between headerAppendix and stationName is automatically inserted.

updatesEvery

The time in seconds when the displayed departures should be updated.

Type: integer
Example: 60 (The departures will be refreshed every minute.)
Default value: 120
Unit: seconds

Note: The minimal refresh time is 30 seconds.

direction

An ID of a station. It is used to display only those departures heading to this station.

Type: string
Example: "954609"
Default value: ""

Note: It is not necessary to find the ID of the end station. Just use the next station which is on the route you are after.
It is not possible to list multiple IDs. If you want to display different directions for one station use multiple instances of this module.

ignoredLines

An array of strings describing the lines you want to exclude from the displayed departures.

Type: array
Example: [ "STR 11", "STR 10" ] (Displays all lines except tram 10 and 11.)
Default value: []

Note: You need to provide the line names exactly as they are otherwise displayed. This setting is case sensitive. Blanks need to be exactly as they are display. If a line is usually displays as BUS 89 (two blanks) you need to type exactly that into the array.

ignoreRelatedStations

Ignore departures from related stations or not.

Type: boolean
Default value: false
Possible values: true and false

Note: Usually you don't need to touch this option.

excludedTransportationTypes

An array of strings describing the transportation types you want to exclude from the displayed departures.

Type: array
Example: [ "suburban", "bus" ]
Default value: []
Possible values:

Type	Use in Germany
`"bus"`	bus
`"ferry"`	Fähre
`"express"`	?
`"national"`	IC trains
`"nationalExpress"`	ICE trains
`"regional"`	RB or RE
`"suburban"`	S-Bahn
`"subway"`	U-Bahn
`"tram"`	Tram
`"taxi"`	Taxi

timeToStation

An integer indicating how long it takes you to get to the station.

Type: integer
Example: 5
Default value: 10
Unit: minutes

timeInFuture

An integer indicating how far in the future a departure can be to be still included in the shown departures.

Type: integer
Example: 60 (Show departures for the next hour.)
Default value: 40
Unit: minutes

Note: Use this setting on stations where there is a big time gap between departures. This way you will see more than one or two departures. Don’t use this setting to limit the amount of displayed departures! The module will set this value to be at least timeToStation + 30 anyway. Use the option maxReachableDepartures to limit the displayed departures.

marqueeLongDirections

A boolean value indicating whether you want scrolling long destination name or not.

Type: boolean
Default value: true
Possible values: true and false

Note: If set to true destination names longer than 24 characters will scroll through the display. If set to false names will be truncated at 24 characters.

replaceInDirections

An object defining strings which are to be replaced in the displayed directions.

Type: object
Example: { "Leipzig": "LE", "\\(Saale\\)": "", "Hbf": "" }
Default value: {}

Note: The strings which appear as the keys of the object will be replaced by their values. Given a direction "Leipzig, Hbf" and the above mentioned example setting the displayed direction will be "LE,". "Leipzig" was replaced by "LE" and "Hbf" was replaced by the empty string. If you want to replace special symbols like "(", ")" or "-" you must escape these characters by placing two "\" in front of the character (see example above).

showColoredLineSymbols

A boolean value indicating whether the line symbols should be colored or black and white.

Type: boolean
Default value: true
Possible values: true and false

Note: If set to true it is possible to decorate the line labels with the colors which are used in your town. This module comes with decorations for Leipzig. To provide your own colors see Providing a custom CSS file.

useColorForRealtimeInfo

A boolean value indicating whether delays should be displayed in color.

Type: booleanDefault value: true
Possible values: true and false

Note: If set to true a delay will be displayed in red. Values <= 0 (transport arrives in time or early) will be displayed in green. If you want to customize that see Providing a custom CSS file.

showAbsoluteTime

A boolean indicating whether the departure time should be displayed as an absolute value or not.

Type: boolean
Default value: true
Possible values: true and false

Note: If set to true the departure time would be displayed as “10:15+0”. If set to false the departure time would be displayed in a relative manner like so: in 5 minutes. The displayed string is determined by your locale. If your locale is set to de the string would be in 5 Minuten.

noRealtimeDelayString

The string that is displayed as delay if no real-time departure time data is available.

Type: String
Default value: "+?"

Note: Set it to "" if you don't want to display a delay string if there is no real-time data. Use an emoji like "⚠" if you want mark departures without real-time data with a symbol.
This is only relevant if showAbsoluteTime is set to true.

showRelativeTimeOnlyUnder

Display the time only relatively if the departure takes place in less than 10 minutes (600000 milliseconds).

Type: integer
Default value: 10*60*1000 (10 minutes)

Note: The value is only relevant if showAbsoluteTime: false.

showTableHeaders

A boolean indicating whether a table header should be shown or not.

Type: boolean
Default value: true
Possible values: true and false

Note: If set to false no table headings like “time” or “direction” will be shown. Also no symbols are shown.

showTableHeadersAsSymbols

A boolean value indicating whether table headers should be shown as symbols or text.

Type: boolean
Default value: true
Possible values: true and false

Note: If set to true table headers will use symbols, else text will be shown. This setting is only effective if showTableHeaders is set to true. The shown text is available in English and German. Feel free to add translations to this project.

showWarningRemarks

A boolean value indicating whether warnings attached to a trip should be shown.

Type: boolean
Default value: true
Possible values: true and false

Note: If set to true and a warning is attached to a trip it will be shown in a additional row. This default width of this row is 80ch, the whole table is then given this width. If you want to change that, set a different value in your custom.css such as: .mmm-pth-warning-remarks { width: 70ch; }.

tableHeaderOrder

An array determining the order of the table headers.

Type: array
Example: [ "line", "direction", "time", "platform" ]
Default value: [ "time", "line", "direction", "platform" ]

Note 1: If the HAFAS API does not provide information about the platforms of your station, you can remove the column here by removing "platform".

Note 2: Sort the table headings as you like it. Please keep in mind that you can only use the values "line", "time", "direction" and "platform".

maxUnreachableDepartures

An integer value denoting how many unreachable departures should be displayed.

Type: integer
Example: 3
Default value: 0

Note: A departure is unreachable if you can't reach the station in time for the departure with respect to your timeToStation setting.
Sometimes it is useful to set this option to a value greater than 0 if you are the type of person which walks really fast. Maybe other users of the mirror usually take 10 minutes to the station but you take only 5. So you’ll see also departures the other users couldn’t reach.

maxReachableDepartures

An integer value denoting how many reachable departures should be displayed.

Type: integer
Example: 5
Default value: 7

Note: A departure is reachable if you can make it to the station in time for the departure with respect to your timeToStation setting.

fadeUnreachableDepartures

A boolean value indicating whether unreachable departures should be dimmed.

Type: boolean
Example: false
Default value: true

fadeReachableDepartures

A boolean value indicating whether reachable departures should be faded out.

Type: boolean
Default value: true
Possible values: true and false

Note: If set to true departures after fadePointForReachableDepartures will be gradually faded out so that the last departure is barely visible.

fadePointForReachableDepartures

A floating point value indicating where to start the fading of departure rows.

Type: float
Example: 0.5 (Start fading after half of the rows.)
Default value: 0.25

Note: This value is actually a percentage. The Default value of 0.25 denotes that after a quarter of the visible rows set by maxReachableDepartures the fading should start. This setting is only effective if fadeReachableDepartures is set to true.

customLineStyles

A string value describing the name of a custom CSS file.

Type: string
Example: "dresden"
Default value: "leipzig"

Note: If the setting showColoredLineSymbols is true the module will try to use colored labels for the line name. Per default it uses the colors used in Leipzig. This style works best if showOnlyLineNumbers is set to true. If it doesn’t suit your taste you can provide your own settings. See Providing a custom CSS file.

showOnlyLineNumbers

A boolean value denoting whether the line name should be displayed as a number only or the full name should be used.

Type: boolean
Default value: false
Possible values: true and false

Note: If set to true the module will try to separate line numbers from the line name and display only these. If the line name is “STR 11” only “11” will be displayed. This only works if there are blanks present in the line name. This setting is only tested with departures in Leipzig. If you encounter problems let me know.

displayLastUpdate

If true this will display the last update time at the end of the task list. See screenshot above

Type: boolean
Default value: true
Possible values: true and false

displayLastUpdateFormat

Format to use for the time display if displayLastUpdate:true

Type: string
Example: 'HH:mm:ss'
Default value: 'dd - HH:mm:ss'

See dayjs.js formats for the other format possibilities.

animationSpeed

Speed of the update animation.

Type: integer
Possible values: 0 - 5000
Default value: 2000
Unit: milliseconds

Configuration example

Here is an example for an entry in the modules array in your config.js:

    {
      module: "MMM-PublicTransportHafas",
      position: "bottom_right",

      config: {
        // Departures options
        stationID: "8012202",                   // Replace with your stationID!
        stationName: "Wilhelm-Leuschner-Platz", // Replace with your station name!
        direction: "",                    // Show only departures heading to this station. (A station ID.)
        excludedTransportationTypes: [],  // Which transportation types should not be shown on the mirror? (comma-separated list of types) possible values: "tram", "bus", "suburban", "subway", "regional" and "national"
        ignoredLines: [],                 // Which lines should be ignored? (comma-separated list of line names)
        timeToStation: 10,                // How long do you need to walk to the next Station?

        // Look and Feel
        displayLastUpdate: true,          // Display the last time of module update.
        maxUnreachableDepartures: 0,      // How many unreachable departures should be shown?
        maxReachableDepartures: 7,        // How many reachable departures should be shown?
        showColoredLineSymbols: true,     // Want colored line symbols?
        customLineStyles: "",             // Prefix for the name of the custom css file. ex: Leipzig-lines.css (case sensitive)
        showOnlyLineNumbers: false,       // Display only the line number instead of the complete name, i. e. "11" instead of "STR 11"
        showTableHeadersAsSymbols: true,  // Table Headers as symbols or text?
        useColorForRealtimeInfo: true     // Want colored real time information (timeToStation, early)?
      }
    },

Multiple instances

It is possible to use multiple instances of this module just by adding another entry of the MMM-PublicTransportHafas module to the config.js of your mirror.

You can even use the same stationID in different instances. So you can display in one instance something like “main station heading eastbound” and in another instance “main station heading westbound”.

Providing a custom CSS file

Note: For some cities, separate CSS files have already been created that contain the local line colors. You can look them up in the css directory. If you create a file for another city, feel free to send it to us.

Colored line labels

If you set showColoredLineSymbols to true the module will try to colorize the line symbols. This is done by appending a CSS class to the line symbol. This class is named after the line name but blanks are left out and all letters are lower case. So if the line name is “STR 11” the appended CSS class name is .str11.

To provide your own classes create a CSS file in the css directory of the module. It must be named like <your custom name>-lines.css, where <your custom name> can be any valid filename but should not contain blanks or dots. The part <your custom name> is then used in the config file as value for the customLineStyles property.

In the example above “leipzig” is used as value for the customLineStyles property. Therefore there must be a file named leipzig-lines.css inside the css directory. If this is not the case the module won’t be started and it will not be visible. The browser’s console will show an error.

Basically you can set whatever you want in the CSS file but it is recommended to only set the foreground and background color and the width. In some cases it is useful to change the border radius too. See the file css/leipzig-lines.css for reference and as a guideline.

Example

In Leipzig the tram lines 2, 8 and 9 use a yellow color. Since the lines share the same settings the CSS class names are listed with commas so that the settings apply to each listed class.

.str2,
.str8,
.str9 {
  background-color: #f8c623; /* yellow background */
  color: black; /* text color black */
}

Some night buses in Leipzig use an orange-ish color.

.busn1,
.busn1e,
.busn5,
.busn5e,
.busn8,
.busn8e {
  background-color: #ee9f2e; /* orange-ish background */
  color: #164585; /* blue-ish text color */
}

Customizing the color for delays

Alongside the departure time a small figure displays the delay as reported by the transport provider.

Delays are displayed as red.

Time with delay

No delay or negative delays (the transport will arrive early) are displayed in green.

Time without delay

Sometimes there is no real-time data for a departure, in that case it is displayed with a question mark:

Time without real time data

If you want to customize that include the classes mmm-pth-has-delay and mmm-pth-to-early in your custom CSS file and make the appropriate settings.

Technical background details

To limit the server request only when the module is displayed and/or the user is present, the update will be stopped when no instance of the module are displayed (module hidden e.g. by a MMM-Carousel, MMM-Pages or MMM-Remote-Control). The update will also be stopped by the use of a PIR sensor using the module MMM-PIR-Sensor (that sends the notification 'USER_PRESENCE'). No special configuration is needed for this behavior.
