I think an integration on the TX unit of weatherduino would be easy possible, if the UART interface ist not used.
At the moment I simply send a scheduled request over uart to the device and poll the results from the uart rx buffer 5 seconds later. It would be better and more efficient to use an interrupt since the measurement takes accordiung to the outer condition a different amount of time. But this could be added easily.
I will give you more details in the evening.
Concerning the davis emulation using the Input of an "extra sensor" is OK because you can measure up to 255cm snow height. Think this is fairly enough in most cases. Moreover a scaling with factor 2 would be imagineable...
Actually I "stole" your davis emulation code to use it in my software at the moment to communicate with CumulusMX running on a PI. Moreover I use a second UART to send all the raw values with full precision as ASCII string to a Server. There I'm generating the graphs and debugging the stuff and evaluate the sensors.
PS. Somewhere is written, that the WeatherDuino supports different 433MHZ rx/tx modules. Is there anywhere a thread where I can see the supported modules? Because I want to set up a decentralized sensor Network and therefore I Need quite some transmission power. Moreover I will start new thread, maybe during the christmas holidays, introducing the sensors I'm using at the moment and my ideas
