The Grainfather is much more than “insert a capsule and wait 2 weeks” though. You have to bring together your ingredients, set and monitor the mash, add your hop additions, chill, clean, properly aerate your wort, pitch the yeast, monitor fermentation temps, package your beer at the end, carbonate it etc etc. It’s completely different.
I’d even argue that machines like the Peco Brew are also home brewing because there’s the programming, bringing together the ingredients, aeration, yeast pitching etc.
