MMM-pekavm

Station monitor for Poznań public transport bus and tram system.

This module is an extension of the amazing MagicMirror² project by MichMich.

It is heavily based upon excellent MMM-KVV module by yo-less. Even this README is 80% coming from there.

Languages

The basis language is Polish (pl) but due to almost identical code to MMM-KVV language support for German (de) and English (en) locales was already possible.

Prerequisite

A working installation of MagicMirror²

You need to add following line on top of ~/MagicMirror/js/app.js and ~/MagicMirror/js/electron.js:

process.binding('http_parser').HTTPParser = require('http-parser-js').HTTPParser;

This needed because PEKA server returns malformed responses that can't be handled by default node.js http parser.

Dependencies

• npm
• request
• http-parser-js

Installation

1. Navigate into your MagicMirror's modules folder.
2. Execute git clone https://github.com/ytmytm/MMM-pekavm.git.
3. Execute cd MMM-pekavm.
4. Execute npm install.

Module behavior

Please note that this module auto-creates a module header which displays the name of the chosen stop. It is therefore recommended not to add a 'header' entry to your config.js for this module.

This module automatically disappears from your mirror as soon as a station has stopped offering connections at night. It reappears as soon as your chosen station is scheduled to be served again.

This module has been programmed to allow for multiple instances. Simply add more MMM-pekavm config entries to your config.js file to display multiple stations and configure them according to your needs.

Configuration

Sample minimum configuration entry for your ~/MagicMirror/config/config.js:

    {
	module: 'MMM-pekavm',
	position: 'top_left',
	config: {
		stopID: 'RKAP46',		// Which stop would you like to have displayed?
	}
    }						// If this isn't your last module, add a comma after the bracket

Sample configuration entry for your ~/MagicMirror/config/config.js with optional parameters:

    {
        module: 'MMM-pekavm',
        position: 'top_left',
        config: {
			stopID: 'RKAP46',	// Which stop would you like to have displayed?
			maxConn: 6,		// How many connections would you like to see?
			lines: ["1","5","238"],	// Which lines to show
			alwaysShowTime: true,	// Always show time of departure? (as HH:MM)
			showMessages: true,	// Show ZTM notifications about canceled lines, reroutes etc.?
			labelRow: true,		// Show or hide column headers
			minTime: 180000,	// Filter out departures earlier than this (in milliseconds)
			reload: 60000		// How often should the information be updated? (in milliseconds)
	}
    }						// If this isn't your last module, add a comma after the bracket

Figuring out the correct stopID

1. Open your web browser and navigate to PEKA Wirtualny monitor.
2. Use the search field to find the stop you are interested in.
3. Once you can see the list of connections in your browser, click on the little text "Bezposredni link do przystanku" on the top right.
4. You will see something like www.peka.poznan.pl/vm/?przystanek=RKAP71
5. This string RKAP71 is the stopID you are looking for.

Or you can just write down this symbol from the physical departures table on your stop.

Or you can search ZTM website and check virtual image of a departures table with stop symbol this link leads to RSTA41.
