NOMWeather

NOMWeather (not open maemo weather) fetches weather data from Open-Meteo.com (FOSS Weather API) and uses IP-API.com for lat/lon discovery via network.

• Supports most locations on the planet
• Temperature in celcius or fahrenheit
• 7 day forecast
• Optional wind data (km/h) and precipitation
• Qt 17, CMake, CCache
• QtWidgets & QtQuick

The application is called not open maemo weather because during development people kept referring to OMWeather (a legacy maemo application).

Repository

On Maemo Leste, nomweather is availabe as a package in the repository:

sudo apt install -y nomweather

It registers a startup item and can be launched from the menu.

Compile

The following command assumes you satisfy the Qt5 depedencies neccesary:

cmake -Bbuild .
make -Cbuild -j2
./build/bin/nomweather

Notes

• Would be nice to support desktop widgets (like OMWeather). Currently unclear how to do this in a preferably Qt-oriented manner.
• When supporting desktop widgets, it is probably best to encapsulate this app's business logic (fetching of API data) in a daemon so both GUI (QtQuick) and the widgets can use that.
• This application works fine on desktop too (e.g: Ubuntu), the fonts are a bit big though.
• There is a config file located at ~/.config/nomweather/settings.json where it saves user preferences.
• This application was made fast (a week) and shortcuts were taken in the QML code.
• Currently only supports landscape mode
• Loading the graph takes 100ms on droid4, should be fine on n900 too. If more speed is needed, more logic related to the graph can be moved to C++.
• To-do: QML theming (other colors)
