A small script that polls the WITS Free to air service using gchan's wits gem, and emails electricity price alerts for New Zealand via mailgun. Note that you will need to know which (parent) grid exit point you are connected to.
Make sure you have modified the .env file to use your own mailgun details.
Modify .ruby-version as you wish.
bundle install
Best run in a screen session:
screen bundle exec ./main.rb

bundle exec ./main.rb --no-output &
