Extracting weather data from WeatherCat

Has anyone done any work to extract weather data from the Mac program WeatherCat? I’d like to include my personal Davis weather station data into my new HA setup.

There doesn’t seem to be any custom integration, so far as I know. Horrible options might include transfer via repeated CSV reports, or AppleScript → a custom Python compont, neither of which I want to get into unless there is really nothing better.

So, to answer my own question, rather than extracting data from WeatherCat it’s apparently possible to get it directly from the Davis datalogger. Thread here: Davis WeatherLink Integration
