solving calculus equations on the forearm but not able to fill in a simple table ... ?

if the below procedure is not basic, then what is ....
no script needed - just to click on two radio buttons and fill in four fields.
(and this is what the WiKi says).
But if you are happy with your solution, whatever that is, some Google app script, having to go via the ecowitt.net website etc., just be happy ...
by the way, when the Ecowitt server goes down, your solution will go down too - the console with the below configuration will not and will continue posting ...
even though the below procedure is far above your level of understanding as you state, just in case, because things can change, I write it still down, if not for you then for other users who might visit this thread
- get yourself a Windy account
- register your station:
https://stations.windy.com/stations- you will get an API key or ID (this will be needed below: [WindyAPIkey] = ID (no brackets !))
- open your web browser with
http://IP-address-of-your-console to access the WebUI of your WS3900
- go to Weather Services (left hand side menu) --> Customized
- enter the data shown in the WiKi into the respective fields
customized: Enabled
protocol same as: Wunderground
IP/hostname: stations.windy.com
path: /pws/update/[windyAPIkey]?
port: 80
interval: 300
the ? in the PATH behind the ID is important and not to be discarded !
