Success...  I've got the CumulusMX software up and running on the RasPi3, and connected to the WeatherDuinoPro2 RX station.  I'm using the built-in wireless adapter on the Pi3.  Stats and data is coming through on the USB, and I've had the Cumulus website (on the Pi) open in a browser on one of my PCs for a couple of hrs now, and all good so far, and no lock ups.  (Note that I don't have the solar sensors connected at this point in time, so those figures will look a little skewed (read: High) in the screenshot)  I've been making heaps of notes and I'll do up a quick "how to" guide sometime soon.

Hello Wizza,
Your posts are a few years old, but they're very interesting for my needs. 
Can my RADDY AG7-DCF weather station, which also transmits at 443 MHz, connect like your WeatherDuinoPro2 RX station?
Of course, I'd like to do it with the Raspberry Pi 4.
Thank you in advance for your help and tips.
