Weather Widget for Dashing

##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.

You may not have noticed if this worked straight off the bat for you, but the job is set to run every 1s - you might want to change that to save any web proxies you sit behind being smashed...

Also related to the comment by @davestephens, the Yahoo APIs generally have a limit for public usage of 2000 requests per hour, which would be exceeded at 1 request per second (3600 requests per hour). I'm not 100% sure if the weather API is included in that limit or not, but it wouldn't be insane to have a default of once every 10 seconds:

SCHEDULER.every '10s', :first_in => 0 do |job|

Actually looking around I think that's a symptom of your post 4 days ago and the need to get some sort of credential. Now to work out how to do that and where to plug it in.

I get the following error since a few days. The widget worked wonderful before:

Hi,

Couldnt plug in the authentication yet, but have a small workaround which works for me, may be it helps.
Please adjust the variables (city, widget url, authentication token etc)

URL='http://www.accuweather.com/en/se/stockholm/314929/weather-forecast/314929'
city="Stockholm"

result=( $(wget -q -O- "$URL" | grep acm_RecentLocationsCarousel.push | grep ${city} | awk -F\' '{printf("%s %s %s",$(NF-5),$(NF-3),$(NF-1));}') )

dStamp=$(date +'%s')
state=${result[@]:2}
temp=${result[0]}
feel=${result[1]}

cmd="curl -d '{ \"auth_token\": \"YOUR_AUTH_TOKEN\", \"temp\":\"${temp}&deg;C (${feel}&deg;C)\",\"condition\":\"${state}\",\"title\":\"${city}\",\"climacon\":\"$( echo ${state} | tr '[:upper:]' '[:lower:]')\",\"id\":\"weather\",\"updatedAt\":${dStamp} }' http://localhost:3030/widgets/weather"

eval $cmd

As noted above Yahoo API is not working properly, on top of that they've added Oauth so it requires more complex implementation. I've made changes to weather.rb now it uses Open Weather API and also repackaged this widget in my own solution here https://github.com/hkraji/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
