Magic Mirror Module: mmm-weatherchart

This MagicMirror2 module allows you to show a weather diagram provided by http://www.yr.no

Installation

In your terminal, go to your MagicMirror's Module folder:

cd ~/MagicMirror/modules

Clone this repository:

git clone https://github.com/paphko/mmm-weatherchart.git

Install module:

cd mmm-weatherchart
npm install

Configure the module in your config.js file.

Using the module

To use this module, you must first determine country, area, and city:

1. go to http://www.yr.no
2. Search for the location you want forecast for
3. Navigate to the bottom of the table to find the link for "Forecast as SVG"
4. Click the link to open in it in a new tab, and copy the url., e.g.: /en/content/2-3196359/meteogram.svg

Now add the module to the modules array in the config/config.js file:

modules: [
	{
		module: 'mmm-weatherchart',
		position: 'bottom_left', // this can be any of the regions
		config: {
			locationPath: "/en/content/2-3196359/meteogram.svg",
			updateInterval: 60 * 60 * 1000, // update every hour
			hideBorder: true, // whether or not a border with city name should be shown
			negativeImage: true, // whether or not the default white image should be inverted
			hoursToShow: 24, // Cut the image down to show less than the full 48 hour forecast. -1 to show everything.
			// mmDirectory: "/home/pi/MagicMirror/" // required for caching; adjust if it differs
		}
	},
]

Configuration options

The following properties can be configured:

Option	Description
Location path	Your url link (after www.yr.no) which determines your location to be shown.
updateInterval	Update interval of the diagram. Default value: 60 * 60 * 1000 (once every hour)
hideBorder	Whether or not a border with city name should be shown. Default value: true
negativeImage	Whether or not the white image should be inverted. Default value: true
hoursToShow	Cut the forecast down to this many hours (for a narrower picture). Default value: -1 (show full forecast)
mmDirectory	To avoid the image to be cached by the browser (issue #5), it is downloaded into the magic mirror / modules / mmm-weatherchart / cache folder. I couldn't find a way to ask MM for this path, so I just hard-coded it here with the possibility to adjust it in case your installation looks different. Default value: /home/pi/MagicMirror/
