There are already a number of low cost and even “free” open source solutions for controlling mashing and fermenting processes - so 2/3 of the “problem” have already been solved. Many of these platforms can be easily used to allow for monitoring of the still as well. Plenty of folks here already using them.
You’ll find that many here, and in the industry in general, are strongly against remote still control, because it enables reckless behaviors, that when go bad, impact all of us from a liability, regulatory, and scrutiny perspective.
