What needs to be measured and recorded, what needs to be controlled? Systems analysis first, decisions on hardware and software very much later.
And yes, how many gallons of aie, and what sort? IPA, winter warmer, mild - all good systems analysis questions I'd say.
Complex , but very acheivable . More complex if you want to fully automate than if you want to actually be around for the brew
Sensor in The HLT . Switch for the element ( set temp and Hold temp )
( If you are going to automate the mash in and the sparge you'll be adding a controlled valve , and possible a volume meter )
Sensor in the mash tun , switch for the element , ( Set temp , time at temp , hold and raise to next temp. )
( If you are going to automate the run to the Boiler , as above you'll want a control valve and a volume meter )
Sensor in the kettle , switch for the heat . ( switch on , Read Boil start , time boil )
If you want to automate hop additions that's another thing to add in .
Cooling to pitching temp ( are you going to do this in the Kettle ? if so the same sensor as was used in the boil )
Sensor in the Fermentor , switch for refrigeration , switch for heat ( set temp range and rules for when to kick either heating or cooling in )
As long as you know how to brew , and what you want to do on your system , the pieces you can automate will stand out to you .
I think the physical operation will be straight forward , but the front end UI will be where you can make it shine .
( it'd be nice to start the HLT an hour before work by logging in over the web , and then after you've mashed in , go off for breakfast and get an email at the start of the boil ...)
