Improvement for gist https://gist.github.com/davefp/4990174 switching to Open Weather API

weather.rb

require 'net/http'

# you can find CITY_ID here http://bulk.openweathermap.org/sample/city.list.json.gz
CITY_ID = 2172517

# options: metric / imperial
UNITS   = 'metric'

# create free account on open weather map to get API key
API_KEY = ENV['WEATHER_KEY']

SCHEDULER.every '60s', :first_in => 0 do |job|

  http = Net::HTTP.new('api.openweathermap.org')
  response = http.request(Net::HTTP::Get.new("/data/2.5/weather?id=#{CITY_ID}&units=#{UNITS}&appid=#{API_KEY}"))

  next unless '200'.eql? response.code

  weather_data  = JSON.parse(response.body)
  detailed_info = weather_data['weather'].first

  send_event('weather', { :temp => "#{weather_data['main']['temp'].to_f.round} °#{temperature_units}",
                          :condition => detailed_info['main'],
                          :title => "#{weather_data['name']} Weather",
                          :climacon => climacon_class(detailed_info['id'])})
end


def temperature_units
  'metric'.eql?(UNITS) ? 'C' : 'K'
end

# fun times ;) legend: http://openweathermap.org/weather-conditions
def climacon_class(weather_code)
  case weather_code.to_s
  when /800/
    'sun'
  when /80./
    'cloud'
  when /2.*/
    'lightning'
  when /3.*/
    'drizzle'
  when /5.*/
    'rain'
  when /6.*/
    'snow'
  else
    'sun'
  end
end

Hey, thanks for the revision, it works well for me. The only update I'd have is that the climacons weren't all correct for me, I came up with this for the climacon_class function:

def climacon_class(weather_code)
  case weather_code.to_i
    when 200..232
      'lightning'
    when 300..321
      'drizzle'
    when 500..531
      'rain'
    when 600..602
      'snow'
    when 611..622
      'sleet'
    when 701..731
      'haze'
    when 741
      'fog'
    when 751..762
      'haze'
    when 771
      'rain'
    when 781
      'tornado'
    when 800
      'sun'
    when 801..803
      'cloud sun'
    when 804
      'cloud'
    when 900
      'tornado'
    when 901..902
      'lightning'
    when 903
      'thermometer low'
    when 904
      'thermometer full'
    when 905
      'wind'
    when 906
      'hail'
    when 951
      'sun'
    when 952..959
      'wind'
    when 960..962
      'lightning'
  end
end
