This is because I did not understood then that the software portion is threefold (I was looking in c, below):
a-> one part for controlling the transmission ("WeatherDuino Pro2 TX Software")
b-> one part for controlling the reception ("WeatherDuino Pro2 RX Software")
c-> one part to make data available by emulating a Davis ("WeatherDuino Pro2 WD Software")

I know nothing about Arduino compilation right now, but as I understand it it takes just one single Arduino to handle parts b and c and deliver data via USB. Correct?

WeatherDuino Pro2 TX Software - Software for the Arduino on the TX unit.

WeatherDuino Pro2 RX Software - Software for the Arduino on the RX unit. It also handles the Davis emulation.

WeatherDuino Pro2 WD Software - Sofware for the Arduino on the Wireless Display units. Think in this units as wireless consoles for your weather station. You may have as many as you wish anywhere in your house. They receives data directly from your main RX unit, that also have a small tx module

If you are now planing to build an WeatherDuino Pro 2 system, I'm gonna tell you a friend advice: despite the appeal of a color TFT display for the RX unit, build it with an 20x4 LCD! You will not regret.

As for our past acquaintance, yes, it's true we had the chance to exchange some thoughts while you were on the first early steps of this project. I guess almost a couple of years ago .

I have recognized your nickname!
Yes, all this started almost three years ago. The time flys
