This an extension for MagicMirror that adds localized weather using the Dark Sky API (originally -- the same service that powers the Dark Sky App.

This module makes use of the geolocation API to determine the location of the mirror. This can be turned off by setting latitude and longitude in the module's config (see Configuration options below).

Unless running headless in a browser, Geolocation requires setting the GOOGLE_API_KEY environment variable.


Using the module

To use this module, add it to the modules array in the config/config.js file:

modules: [
    module: 'MMM-forecast-io',
    position: 'top_right',  // This can be any of the regions.
    config: {
      // See 'Configuration options' for more information.
      apiKey: 'abcde12345abcde12345abcde12345ab', // Dark Sky API key.
      // Only required if geolocation doesn't work:
      latitude:   16.77532,
      longitude: -3.008265

Configuration options

Option Description
apiKey The Dark Sky API key, which can be obtained by creating an Dark Sky API account.

This value is REQUIRED
units What units to use. Specified by config.js

Possible values: config.units = Specified by config.js, default = Kelvin, metric = Celsius, imperial =Fahrenheit
Default value: config.units
language The language of the weather text.

Possible values: en, nl, ru, etc ...
Default value: uses value of config.language
updateInterval How often does the content needs to be fetched? (Milliseconds) enforces a 1,000/day request limit, so if you run your mirror constantly, anything below 90,000 (every 1.5 minutes) may require payment information or be blocked.

Possible values: 1000 - 86400000
Default value: 300000 (5 minutes)
animationSpeed Speed of the update animation. (Milliseconds)

Possible values:0 - 5000
Default value: 2000 (2 seconds)
initialLoadDelay The initial delay before loading. If you have multiple modules that use the same API key, you might want to delay one of the requests. (Milliseconds)

Possible values: 1000 - 5000
Default value: 0
retryDelay The delay before retrying after a request failure. (Milliseconds)

Possible values: 1000 - 60000
Default value: 2500
latitude The latitude location in decimal. Set this (and longitude) as the location for the forecast. If this is not set, the module will attempt to approximate using browser geolocation.

Example value: 16.77532
Default value: null
longitude The longitude location in decimal. Set this (and latitude) as the location for the forecast. If this is not set, the module will attempt to approximate using browser geolocation.

Example value: -3.008265
Default value: null

Default value: true
apiBase The Dark Sky API base URL.

Default value: ''
showForecast Toggles display of the seven-day weather forecast.

Default value: true
showFeelsLike Toggles display of the local "feels like" temperature. Feels like is the ambient air temperature, adjusted for relative humidity and wind speed to determine how weather conditions feel to bare skin.

Default value: false
fadeForecast Toggles fading of last 2 forecast rows.

Default value: false
maxDaysForecast Limit how many days of weather forecast. Useful values 1-7

Default value: 7
showSunriseSunset Toggles display of sunrise and sunset times

enablePrecipitationGraph Toggles display of the precipitation graph.

Default value: true
alwaysShowPrecipitationGraph Force the precipition graph to always show, and not just when it's raining.

Default value: false
precipitationFillColor Choose the color of the precipitation graph. Will accept hex value or color names of Javascript-friendly colors. See this page for a list of colors. "dodgerblue" appears to best mimic the Dark Sky app.

Default value: white
precipitationGraphWidth Width of the precipitation graph element in pixels. Scales height to match.

Default value: 400
forecastTableFontSize Sets CSS font style for forecast table. Possible values: 'xsmall', 'small', 'medium', 'large', 'xlarge'

Default value: 'medium'
precipitationProbabilityThreshold Probability threshold at which rain is rendered onto the precipitation graph.
See the API documentation for more details.

Default value: 0.1
showDailyPrecipitationChance Toggles display of the precipitation probability for each day.

Default value: true
iconTable The conversion table to convert the weather conditions to weather-icons.

Default value:
iconTable: {
