Velleman vm201

[dari]

I would like to switch the relays of the vm201 module from velleman on and off with buttons from the demopad
The relays can be switched on and off individually via the internet (toggle) by following command
http://192.168.2.150/cgi/leds.cgi?led=4
(led = 0 t/m 7depending on which relay must be switched)
8 relays can be switched with the VM 201 module
How can I do this with a demopad button?
