rhjbarney so is it just a matter of plug to SSR? Nothing in between them? Then the Fireboard to trigger the SSR?

Assume you complete the circuit for the SSR. Do you have an earth on the cabinet itself?

Any more info on this? I’m hoping to do the same thing but I know I’m missing a step. Unsure how to wire up an SSR to the heating element. I get how the Fireboard drive cable can switch the SSR, but most diagrams are using an Auber PID that handles the main voltage.

Do you have another device that handles the main voltage from the plug to the heating element?
