In 2020, I posted here about my new weather station in Setting Up a Weather Station (Specifically, My Weather Station). The station is no longer new, and the software running it was no longer supported, so I upgraded it and added an improved (and supported) Bosch BMP280 pressure sensor in the bargain. The sensor had no service definition to make it work with WeeWX weather software, so I wrote one. I put this simple adapter on GitHub so that others could benefit from my educational process. The code and the documentation for it are at BMP280-WeeWX.
