On the Pi you simply need to activate the drivers. Check if it is already activated with

lsmod | grep cp210x
You should now see nothing or else it might already be activated. Insert “cp210x” into “/etc/modules” and execute “modprobe cp210x”.
After a reboot you should be able to see the WDE listed with “dmesg
lunetikk@weather:~# dmesg | grep WDE
[   45.750999] usb 1-1.3: Product: ELV USB-WDE1 Wetterdatenempf\xffffffc3\xffffffa4nger

With the Software “Socat” you can do a testrun to check if your WDE finds your device and receives data.

sudo apt-get install socat
sudo socat /dev/ttyUSB0,b9600 STDOUT
