This is a sample application that uses the Green Button gem to parse data collected from a server that responds to GET requests for Green Button usage points.

It is built using Sinatra and HighCharts, and is merely meant to provide a simple example of the Green Button parser library at work.

You will need Ruby installed.

To run locally, clone the repository, cd into the repo, and run $ bundle install. Then, $ ruby gbsample.rb to start a server. Visit http://localhost:4567/greenbutton to initiate a request to the sample Green Button data endpoint (in this case https://services.greenbuttondata.org/DataCustodian/espi/1_1/resource/Batch/RetailCustomer/1/UsagePoint). Once the file has been loaded from the server, it will be parsed and displayed on the chart.

The action happens in gbsample.rb.

The app, such as it is, is deployed on Heroku. You can test it by visiting http://gbsample.herokuapp.com/greenbutton.
