Raspberry Relay not working

Hello folks,

I have a raspberry pi 2 and an 8 channel relay , the rasp is succefully added to cayenne and work however i connected the relay but doesn’t work

The gpio physics is 26 so the logic channel should be 25
I tried few gpio and different relay but same issue

Thanks !

the channel you select for the button is same number as the GPIO.

Got it thanks ! and my wiring was wrong
