MMM-PublicTransportDB

MMM-PublicTransportDB is a module for the MagicMirror project by Michael Teeuw.

It shows live public transport information for Germany based on DB-Hafas data. MMM-PublicTransportDB uses the db-hafas library by derhuerst. It primarily displays data from the Deutsche Bahn, but also includes local networks that integrate their data into the DB network. Most, if not all, local transport networks in Germany should work. Following ones are tested:

• RMV (Rhein-Main/Hessen): missing delays for buses, trams and subway

Notes:

• The module is working fine. But I think some value combinations could still lead to strange behaviour. I'd appreciate any error report.
• Fading for departures with delay = 0 is not yet implemented

You can enter a delay time for "How long does it take to get to my station?". Then the module calculates the next reachable departures and draws a line between reachable and unreachable departures.

The module looks like this:

Installation

Just clone the module into your MagicMirror modules folder and execute npm install in the module directory:

git clone https://github.com/olexs/MMM-PublicTransportDB.git
cd MMM-PublicTransportDB
npm install

How to get the stationId

You will need a stationId for your module from the DB network. TODO Link full list or query target to get station IDs.

Configuration

The module quite configurable. These are the possible options:

Option	Description
name	The name of the module instance (if you want multiple modules). Type: string
stationId	The ID of the station. How to get the ID for your station is described below. Type: integer This value is Required.
ignoredStations	To allow appearance of multiple transportation methods, vbb-hafas returns departures of multiple stations in the area of the main station (including bus and tram stations for example). You can exclude those stations by adding them to this array. Usually, this can be empty. Type: integer array (comma separated integers in the array). Default value: <empty>
excludedTransportationTypes	Transportation types to be excluded from appearing on a module instance can be listed here. Type: string, comma-separated list Default vaule: <empty> Possible values: bus, tram, suburban, subway, regional, ferry
marqueeLongDirections	Makes a marquee/ticker text out of all direction descriptions with more than 25 characters. If this value is false, the descriptions are trimmed to the station names. You can see a video of it here (rendered by a regular computer). Note: The rendering on the mirror is not perfect, but it is OK in my opinion. If the movement is not fluent enough for you, you should turn it off. Type: boolean Default vaule: true
interval	How often the module should be updated. The value is given in milliseconds. Type: integer Default value: 120000 // 2 minutes
hidden	Visibility of the module. Type: boolean Default vaule: false
delay	How long does it take you to get from the mirror to the station? The value is given in minutes. Type: integer Default vaule: 10 // 10 minutes
departureMinutes	For how many minutes in the future should departures be fetched? If delay is set > 0, then this time will be added to now() + delay. (This could be obsolete in future versions but is needed for now.) Type: integer Default vaule: 10
showColoredLineSymbols	If you want the line colored and shaped or text only. Type: boolean Default vaule: true
useColorForRealtimeInfo	Set colors for realtime information Type: boolean Default vaule: true
showTableHeadersAsSymbols	Show the table headers as text or symbols. Type: boolean Default vaule: true
maxUnreachableDepartures	How many unreachable departures should be shown. Only necessary, of you set delay > 0 Type: integer Default vaule: 3
maxReachableDepartures	How many reachable departures should be shown. If your delay = 0, this is the value for the number of departures you want to see. Type: integer Default vaule: 7
fadeUnreachableDepartures	Activates/deactivates fading for unreachable departures. Type: boolean Default vaule: true
fadeReachableDepartures	Activates/deactivates fading for reachable departures. Type: boolean Default vaule: true
fadePointForReachableDepartures	Fading point for reachable departures. Type: float Default vaule: 0.5 Possible values: 0.0 - 1.0

TODO: Add new configuration values

Here is an example of an entry in config.js:

{
    module: 'MMM-PublicTransportBerlin',
    position: 'top_right',
    config: {
        name: "Alexanderplatz",
        stationId: 9160003,
        hidden: false,
        ignoredStations: [9100003,2342,1337], 
        excludedTransportationTypes: 'bus,suburban,subway',   
        delay: 10,
        interval: 120000,
        departureMinutes: 10,          
        maxDepartures: 15,
        marqueeLongDirections: true,
        showColoredLineSymbols: true,  
        useColorForRealtimeInfo: true,
        showTableHeadersAsSymbols: true,
        maxUnreachableDepartures: 3,    
        maxReachableDepartures: 7,
        fadeUnreachableDepartures: true,
        fadeReachableDepartures: true,
        fadePointForReachableDepartures: 0.25
    }
},

Multiple Modules

Multiple instances of this module are possible. Just add another entry of the MMM-PublicTransportBerlin module to the config.js of your mirror.
