RAPP Weather Reporter

RAPP Weather Reporter allows users to get details about current or future weather conditions. It provides two services; a) current weather conditions and b) weather forecast. The user has to provide his current city, which could be evaluated using RAPP Geolocator. The availability of weather services that rely on third party APIs such as YWeahter are restricted according to the APIs' rules and limitations. Thus, service call failures may exist.

Currently supported weather reporters:

• YWeather
• ForecastIO (default)

In order for the ForecastIO weather reporter to be deployed an API key is required. After obtaining the key via registration, the key should be stored in the following location:

${HOME}/.config/rapp_platform/api_keys/forecast.io
