Astronomy Weather

Astronomy Weather is a cross-platform application that provides real-time weather data from Open Meteo stations. Built with Avalonia UI, it runs on a single .NET codebase, making it compatible with desktop systems on Windows and macOS, as well as low-power devices like the Raspberry Pi. The app delivers accurate and timely weather information across a variety of platforms.

The application demonstrates Avalonia UI’s flexibility, offering a consistent experience across desktops, embedded systems, and mobile devices. Users can access detailed weather information through a straightforward interface that balances functionality with clarity, making it suitable for both hobbyists and technical users who need reliable, real-time data.

Releases

1.0.5

• Adjusted Current Forecast to handle longer status text without strangely scaling the window.
• Mac: Updated configuration to refer to Astronomy Weather correctly in the Application manager vs “Avalonia Application”.
• Various code improvements.
• A few minor UI tweaks.

1.0.4

• Corrected Support and Help URL’s for Windows installation.
• Added a message to the locations lookup screen when the API key is invalid.
• Removed preferences.json by default. Only create if it doesn’t exist. Should avoid overwrite on upgrade.
• AQI: Reduced description length.
• AQI: Added color coding to each pollutant to give more indication why the AQI level is where it is.
• Preferences: Refresh no longer allows a more aggressive update time than 10 minutes to avoid capping out API usage requirements.
• Performance: API’s now load asynchronously, improving load times.
• Reliability: In situations where certain views do not get data in time, the previous data remains instead of appearing blank.

1.0.3

• Temperature Values: Changed “-0” readings to appear as “0”.
• Pressure: Changed “Normal” to “Norm” to take up less space on the view which can force truncation of the graphic.
• Hourly Forecast: Fix consistencies with AM / PM text in ARM mode.
• Sun/Moon: Align 6AM, 6PM to be closer to graphic when stretching horizontally.
• Preferences: Fix formatting to match “Locations” and “About Us”.
• Multiple Views: Hide Text-based ToolTips in Pi mode. They are more distracting than helpful.

1.0.2

• Official Production Release for Windows, Linux x64, Linux ARM, and Mac OS.
