HTTP commands

Hi Guys!

Great equipment this one from velleman! Anyway, i don’t know if you guys are familiar with iRule but its an iOs app that allows to link http commands to a button on this application.

I can get the first relay to change it’s status, for example: through this command:

(VM201ip/cgi/leds.cgi?led=0

but I need to create a button (and for that I need a http command) to turn off ALL relays.

I can attached multiple commands to a button so, using this command I can change the status of all the relays. But I’ll not be sure that all of them are OFF. Is there a command for that?
a http line that makes sure the one’s that are OFF remains OFF and the other one’s change it’s status?

Thanks in advance,
Joao
