FYI, I just cobbled together a working weewx driver interface for the WeatherFlow UDP broadcast protocol. It ignores the sensor addresses for now, so it will get confused if there are more than one sensor unit of a given type attached to the Hub.
I still plan to implement the tuple sensor names and mappings like the SDR driver does to allow multiple sensor units, but will have to dig around that driver to see how it works. As I said, Python might as well be Klingon to me. I'll throw it up on Github once I have seen it run for a few days without problems. If anyone wants to live dangerous, reply here and I'll upload what I'm testing.....
