WeeWX

WeeWX is an open source weather station system written in Python. It collects data from many supported weather stations and sensors, stores it locally, and generates graphs, reports, and HTML pages that can be published to a website or uploaded to online weather services.

Key Features

• Broad hardware support through drivers for many popular weather stations and sensors
• Generates plots, HTML pages, and monthly/yearly summary reports
• Database-backed storage with built-in support for SQLite and MySQL
• Upload/publish outputs to web servers (including rsync-based publishing) and to multiple weather services
• Extensible architecture with a large ecosystem of third-party extensions and skins
• Localization support (language, date/time formats, units)
• Data quality features such as calibration corrections and filtering of anomalous values

Use Cases

• Run a home weather station on a Raspberry Pi and publish a personal weather website
• Collect and archive long-term weather observations with automated summary reporting
• Forward station data to public aggregation services and dashboards

Limitations and Considerations

• Hardware compatibility depends on available drivers for a given station model and connection method
• Windows support exists but is not widely supported compared to Unix-like platforms

WeeWX is a practical choice for enthusiasts and operators who want reliable local collection, flexible reporting, and multiple publishing options. Its modular design and skin/extension ecosystem make it well-suited to customized weather data sites and integrations.
