Since I don’t actually own a BrewPi yet, this may sound silly. Sorry in advance.
I’ve designed a mechanically automated system that has 14 mechanically controlled valves, 2 heating elements and 2 pumps (controlled by SSRs), and 8 temperature probes. Can a single BrewPi Spark 3 handle this?
I know that the valve and SSR expansion boards will allow me to expand what the BrewPi can control. Am I correct in assuming that for my setup configuration (above), I would use the 5 RJ12 connection ports in conjunction with the expansion boards, and the actuator controls for my SSRs?
Can the expansion boards be daisy-chained together?
Is my maximum valve control limited to 10 valves per BrewPi (excluding the actuators)?
Otherwise, it would seem that I have 18 devices to control, but only 15 ports to manage them with. Please set me straight.
I want to eventually add a fermentation chamber (hacked fridge) to the mix as well and would love to know if I have the ability to expand.
Thanks in advance!
