KNX PIR detection should execute url (WLED)

[MaGer]

Hello all,

I am currently struggling with the integration of my WLED environment.
https://github.com/Aircoookie/WLED

The goal is that when my KNX motion detectors detect a movement their group address jumps to 1, that then a URL is called which activates the preset provided in the WLED controller. At 0, the 2nd URL should be executed, which again deactivates the lights.
With the URLs no value must be given, but only the URL must be called.
How must the script look, or where do I have to store this, so that it does not require too much performance.
Scripting => Event-Controlled => Add new script????

Here is the final score of my futile attempts:

################## START ######################

PIR1 = grp.getvalue('1/1/19')
PIR2 = grp.getvalue('1/1/20')
WLEDon = 'http://192.168.178.128/win&T=1'
WLEDoff = 'http://192.168.178.128/win&T=0'

http = require('socket.http')

if PIR1 or PIR2 == 1 then
http = 'http://192.168.178.128/win&T=1'
else
url = 'http://192.168.178.128/win&T=0'
end
