Finally a use for my Pi. I am in the process of switching to an electric setup. Due to limited space this will just be a single kettle batch sparge setup in the basement. I think this might be the solution I have been looking for the ability to set some parameters and monitor remotely and come back when I have hit targets in the brew process.
I have determined that I will need a relay block either USB or GPIO to control the SSRs to drive the element and random pumps ect...
What I am not sure about is the temperature sensors.What is the general consensus for connecting the temperature sensors USB or GPIO?
Here are some ideas of parts I am considering
USB relay and input controller
