Weather Widget for Dashing

README.md

##Preview

Description

Simple Dashing widget (and associated job) to display weather info. Uses Yahoo's weather API.

##Dependencies

xml-simple

Add it to dashing's gemfile:

gem 'xml-simple'

and run bundle install. Everything should work now :)

##Usage

To use this widget, copy weather.html, weather.coffee, and weather.scss into the /widgets/weather directory. Put the weather.rb file in your /jobs folder.

You'll also need the Climacons Webfont. Download it, and put the .eot, .ttf, and .woff files in your /assets/fonts folder

To include the widget in a dashboard, add the following snippet to the dashboard layout file:

<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
  <div data-id="weather" data-view="Weather"></div>
</li>

##Settings

You'll need to add the WOEID for your desired location to the job (you'll get Ottawa's weather by default). Find your WOEID here.

Temperatures are fetched and displayed in Centigrade, but you can change it to Fahrenheit by replacing format = 'c' to format = 'f' at the top of the job file.

Weather is fetched every 15 minutes, but you can change that by editing the job schedule.

@hkraji: Any idea how to add weather forecast (over n days) to yours?

here's a fixed and improved version: https://github.com/Montaxx/weather-widget

Hi @Montaxx,

I am getting an issue on my dashboard where the box is just appearing blue ? not sure if anyone else has had this issue. I have followed the steps in the new version and put everything in place: https://github.com/Montaxx/weather-widget

Not sure how to troubleshoot as the next steps because the thin.log file doesn't show any issues either..

Any idea ?

Thanks

Update - I fixed this don't worry, appears that there was a binding left in a

tag so alls good!

I keep getting this error

scheduler caught exception:

can someone assist me? Or is this widget out of date and the yahooweatherapis are no longer being used

Yahoo discontinued their APIs. Switch to another Widget for weather.

Thanks @hkraji ! Your project works!

The site listed for getting WOEID doesn't works anymore, I have found an amazing alternative. Find Your WOEID here: https://nations24.com. Make change in the gist if possible.

Yahoo discontinued their APIs. Switch to another Widget for weather.

Check out https://weathercodes.nations24.com/

Here is an up-to-date version of this widget working with OpenWeatherMap API.
I made also some customisations concerning the icons : https://github.com/aymanebarka/Weather-Dashing
