3) What is the pin explanation of the wind and rain sockets? (i.e.
pin 1: power
pin2: digital data for wind direction
pin 3: ....)
Answer of third question wil be very useful to prepare DIY solutions.

Hi,

If you plan to implement some DIY solutions, it will be good take a look to the TX v2.50 board schematics and to the code too. Doing this, will give you some light.

RJ11 Pin1 and Pin2 goes to GND
RJ11 Pin3 goes to an Arduino digital pin
RJ11 Pin4 goes to an Arduino analog pin

So, RJ11 Pin3 is digital data from anemometer, and RJ11 Pin 4 is analog signal from wind vane.

There is no permanent power pin at the RJ11 connector. The power for the wind vane is switched on and off just before any reading, and is supplied to the wind vane through R8.

Of course, I can not give support, for any personal user modifications.
