I have a Nextion Display, Photon and a 4 relay board. I want to be able to push a button on the Display and turn on one of the relays and then push again to turn off the relay.I have Particle.Fuction working and I can control the relay from console.particle.io but i have 8 separate functions.
here is the code
#include <Particle_SI7021.h>
#include <ITEADLIB_Nextion.h>
