• Configurable temperature units. (US, SI, UK)
• Default schedule set to fetch weather every 5 minutes but can be changed from within forcast.rb.

@adityai that might happen if you didn't include the widget in the dashboard template (see "Usage")

Thank you. It worked. I had saved the forecast.coffee file as forecast.coffee.txt and didn't realize till I saw your message.

Firstly, Thankyou this is awesome.

For some reason this was "minutely" as the top level key, Was causing exception on line 24.

Needs to be hourly to match json from forecast.io

forecast_hour_summary = forecast["hourly"]["summary"]

Hey, I've been playing around with your widget and made some changes to better support and handle the forecast.io API. I'd appreciate any comments, and it would be nice to see those changes incorporated here.

Hi, I downloaded the files and added my api key and location. However, all I can see on my dashboard is this. Any ideas how I can fix this?

Edit: I have no idea what I did, but now it works. Maybe I needed to run bundle install.

I'm having the same problem, but bundle install doesn't seem to be the solution.
