@gabba - Thanks for the reply and for the links to the instruction page for setting up WD on RPi. I followed your exact procedure and manged to get the WD run on my RPi, but facing some issues. I wanted to connect my old Acurite, but it seems the WD on Linux doesn't support Acurite stations, so I tried with a Tempest station and tried to upload data to Weather Underground, but it only transmits, temperature, dew point and pressure data correctly. The wind speed and wind direction data is not correct, also, when it comes to rain, UV and solar radiation data, it is not updated in WU. Any help would be much appreciated.
