I am new to particle. I want to enable light control with IFTTT. Came across the 4 channel photon relay board and the photon WIFI module. I wanted to know if I need anything else to program/communicate. Also, if there is any instructions on how to configure these two that would be helpful.
That’s a great Particle project! You shouldn’t need anything else as those hardware products are designed to work with one another.
