Weather sources

This is a user-end guide to weather sources available in climasense. If you are a developer looking to add a new source in climasense, have a look at contribute.

AccuWeather is the most complete source, although you may not need so much completeness (not many people cares about ceiling, for example).

Open-Meteo is the only free and open source weather source on this list, and probably also the most privacy-friendly. It is nearly as complete as AccuWeather, however lacks major features (alerts, realtime precipitations and reverse geocoding). Pollen is available and remains to be implemented.

When deciding about which source you want to use, accuracy of data is probably the most important criteria, however only you can know which one is the best for your country.

Ultimate goal of the app would be to modularize as to have a main weather source, and then being able to complete “precipitations in next hour” and “alerts” from one or more sources.
