WeeWX in a nutshell

See the top-level Weewx Home Page description

How is the software written

Other than a few system startup configuration files, WeeWX is written in pure python, with python3 preferred and python2 still supported as of this writing. Given that python2 is past end-of-life, it can be expected that python2 compatibility will be dropped in some future version of WeeWX.

How is WeeWX architected

The best description is in the Introduction section of the Customization Guide.

Some terminology you will see

• drivers - collect data from various primary sources
• extensions - add capabilities to a WeeWX installation
• services - collect and emit data
• skins - contain the templates for generating report
• uploaders - transfer data to online services

You may have 'one' driver per weewx installation, but multiple extensions/services/skins/uploaders per installation.

Prerequisite software

WeeWX relies on the python PIL image libraries and the Cheetah templating engine, and either sqlite3 or mysql/mariadb for its database. You may optionally add pyephem to get more accurate astronomical data (sunrise/sunset, phase of the moon etc.) in your reports
