MMM-OpenWeatherMapForecast

This a module for MagicMirror².

A weather module that displays current, hourly and daily forecast information using data from the OpenWeather One Call API. This is a replacement module for MMM-MyWeather, now that Weather Underground no longer allows free API access. This a complete rewrite from scratch but maintains much of the same functionality.

gerjomarty reworked the module to use OpenWeatherMap after Dark Sky no longer accepts free API access.

NOTE: This module uses the Nunjucks templating system introduced in version 2.2.0 of MagicMirror. If you're seeing nothing on your display where you expect this module to appear, make sure your MagicMirror version is at least 2.2.0.

Installation

1. Execute the following commands to install the module:

cd ~/MagicMirror/modules # navigate to module folder
git clone https://github.com/MarcLandis/MMM-OpenWeatherMapForecast # clone this repository
cd MMM-OpenWeatherMapForecast
npm install # install dependencies

2. Then, add the following into the modules section of your config/config.js file:

{
    module: 'MMM-OpenWeatherMapForecast',
    position: 'top_left',
    config: {
        // See 'Configuration' for more information.
    }
},

Update

Execute the following commands to install the module:

cd ~/MagicMirror/modules/MMM-OpenWeatherMapForecast
git pull
npm install

Configuration

At a minimum you need to supply the following required configuration parameters:

• apikey
• latitude
• longitude

You can request an API key to access data here: https://openweathermap.org/api/one-call-api.

Free tier is fine -- this module will not make any where near 1000 request on one day.

Find out your latitude and longitude here: https://www.latlong.net/.

Other optional parameters

Option	Description
endpoint	The URL of the onecall api; v2.5 is free but deprecated, v3.0 requires a subscription with payment info and can be used with https://api.openweathermap.org/data/3.0/onecall. Type String Defaults to https://api.openweathermap.org/data/3.0/onecall
updateInterval	How frequently, in minutes, to poll for data. Be careful not to set this too frequent so that you don't exceed Dark Sky's 1000 free requests per day cap. Type Number Defaults to 10
requestDelay	In milliseconds, how long to delay the request. If you have multiple instances of the module running, set one of them to a delay of a second or two to keep the API calls from being too close together. Type Number Defaults to 250
updateFadeSpeed	How quickly in milliseconds to fade the module out and in upon data refresh. Set this to 0 for no fade. Type Number Defaults to 500 (i.e.: 1/2 second).
language	The language to be used for display. Type String Defaults to the language set for MagicMirror², but can be overridden with any of the language codes listed here: https://openweathermap.org/api/one-call-api#multi.
colored	Whether to present module in colour or black-and-white. Note, if set to false, the monochramtic version of your chosen icon set will be forced if it exist. Type Boolean Defaults to true
units	One of the following: imperial, metric, or [blank]. Type String Defaults to units set for MagicMirror². See https://openweathermap.org/api/one-call-api#data for details on units.
showCurrentConditions	Whether to show current temperaure and current conditions icon. Type Boolean Defaults to true
showExtraCurrentConditions	Whether to show additional current conditions such as high/low temperatures, precipitation and wind speed. Type Boolean Defaults to true
showSummary	Whether to show the forecast summary. Type Boolean Defaults to true
forecastHeaderText	Show a header above the forecast display. Type String Defaults to ""
showForecastTableColumnHeaderIcons	Whether to show icons column headers on the forecast table. Type Boolean Defaults to true
showHourlyForecast	Whether to show hourly forecast information. when set to true it works with the hourlyForecastInterval and maxHourliesToShow parameters. Type Boolean Defaults to true
hourlyForecastInterval	How many hours apart each listed hourly forecast is. Type Number Defaults to 3
maxHourliesToShow	How many hourly forecasts to list. Type Number Defaults to 3
showDailyForecast	Whether to show daily forecast information. when set to true it works with the maxDailiesToShow parameter. Type Boolean Defaults to true
maxDailiesToShow	How many daily forecasts to list. Type Number Defaults to 3
showPrecipitation	Whether to show precipitation information. This affects current conditions, hourly and daily forecasts Type Boolean Defaults to true
showWind	Whether to show wind information. This affects current conditions, hourly and daily forecasts Type Boolean Defaults to true
concise	When set to true, this presents less information. (e.g.: shorter summary, no precipitation accumulation, no wind gusts, etc.) Type Boolean Defaults to true
iconset	Which icon set to use. See below for previews of the icon sets. Type String Defaults to 1c
mainIconset	Which icon set to use for current weather. See below for previews of the icon sets. Type String Defaults to iconset value
useAnimatedIcons	*** LEGACY, please use icon set '6fa' or '6oa' for animated icons *** Whether to use the Dark Sky's own animated icon set. When set to true, this will override your choice for iconset. However, flat icons will still be used in some instances. For example if you set the animateMainIconOnly parameter to true, daily and hourly forecasts will not be animated and instead will use your choice for iconset. Inline icons (i.e. used to prefix precipitation and wind information) will always be flat. A good iconset match for the animated set is 1c. Type Boolean Defaults to true
animateMainIconOnly	When set to true, only the main current conditions icon is animated. The rest use your choice for iconset (1c is a good match for the animated icon). If you are running on a low-powered device like a Raspberry Pi, performance may suffer if you set this to false. In my testing on a Pi 3b, enabling this ramped up CPU temperature by 15° - 20°, and fade transitions were not smooth. Type Boolean Defaults to true
showInlineIcons	Whether to prefix wind and precipitation information with an icon. Only affects the tiled layout. Type Boolean Defaults to true
forecastLayout	Can be set to tiled or table. How to display hourly and forecast information. See below for screenshot examples of each. Type String Defaults to tiled
label_maximum	The label you wish to display for prefixing wind gusts. Type String Defaults to "max".
label_high	The label you wish to display for prefixing high temperature. Type String Defaults to "H".
label_low	The label you wish to display for prefixing low temperature. Type String Defaults to "L".
label_timeFormat	How you want the time formatted for hourly forecast display. Accepts any valid moment.js format (https://momentjs.com/docs/#/displaying/format/). For example, specify short 24h format with "k[h]" (e.g.: 14h) Type String Defaults to "h a" (e.g.: 9 am)
label_days	How you would like the days of the week displayed for daily forecasts. Assumes index 0 is Sunday. Type Array of Strings Defaults to ["Sun", "Mon", "Tue", "Wed", "Thur", "Fri", "Sat"]
label_ordinals	How you would like wind direction to be displayed. Assumes index 0 is North and proceeds clockwise. Type Array of Strings Defaults to ["N", "NNE", "NE", "ENE", "E", "ESE", "SE", "SSE", "S", "SSW", "SW", "WSW", "W", "WNW", "NW", "NNW"]
