==== Info ====

[[https://de.elv.com/elv-usb-wetterdaten-empfaenger-usb-wde1-2-104656?fs=1640358625|ELV-Shop -> USB-WDE]]

==== Installation ====

On the Pi you simply need to activate the drivers. Check if it is already activated with <code bash>lsmod | grep cp210x</code>
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//"
<code bash>lunetikk@weather:~# dmesg | grep WDE
[   45.750999] usb 1-1.3: Product: ELV USB-WDE1 Wetterdatenempf\xffffffc3\xffffffa4nger
</code>

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

<code bash>sudo apt-get install socat
sudo socat /dev/ttyUSB0,b9600 STDOUT

Output:
$1;1;;25,8;53,2;;;28,1;;;;53;;;;53;;;;;;;;;0
$1;1;;25,8;53,2;;;28,0;;;;53;;;;51;;;;;;;;;0
</code>

Remove the USB-WDE and plug it in after the boot is done.
