I'm bad with raspberry pi, I've read and read, and I've tried to figure out a way to do what I want and need to. Let me lay it out and maybe there are suggestions? I need to build a brew controller box to replace mine.
Currently my brew controller consists of:
-240v 40a input power to DPST relays
-Switchable between PID control and PWM controller for mash temp and boil rate respectively (only run one mode at a time)
-temp sensing input via PID
-power output to a 4500w heating element (via SSR for PID and standard relay for PWM)
-separate switched 110v output to run recirculation pump.
So I need raspberry pi to simply control a relay set, sense temp and adjust like a PID module would, and have a secondary PWM mode (which I know exists). Am I dreaming that I can do this with simple manual controls but pi can't?
