OSW WEATHER

How to install

  • Add the flag OSW_FEATURE_WEATHER to the file platformio.ini

Getting the API key

The weather updates are provided by openweathermap.org, so you need a valid API key.

  • Create an account here
  • Select a free plan
  • From your account select "my API keys" and generate a key.

Configuration

It's possible to configure the app from both the web UI and the configuration file config_defaults.h

Web UI

  • Paste your API key in the field API key for Openweathermap.org
  • Write the name of the location of your interest in the field City name
  • Write the two letters iso code of the country associated with your location in the field Country code. You can search the two letters code of a given country here selecting country codes.
  • Save

Without web UI

If you want to configure the app without using the web UI you can set the followings values in config_defaults.h:

  • OPENWEATHERMAP_APIKEY, the api key
  • OPENWEATHERMAP_CITY, city name
  • OPENWEATHERMAP__STATE_CODE, the two letter iso code of the country of your interest

If you are not sure about the geocoding you can perform a simple test. Type in the address bar of your browser: "https://api.openweathermap.org/data/2.5/forecast?q=CITY,STATE&appid=APIKEY&cnt=24 " substituting CITY, STATE and APIKEY with: city name, two letters code and api key. Beware not to past additional characters, the country code must be separated by a comma from the city name. If you get an answer like this: {"cod":"200" ... both api key and location are valid.
