When I had a beer keg on a turkey burner, I had a wristwatch stopwatch and one thermometer. I measured the temp of the cooling water outflow to keep it below 140F.

There are several distilleries that I have been to, that after investing hundreds of thousands up to million on beautiful stills, went out and hired someone to run it. Or gave up and started buying commodity booze to bottle.
One, while they were building, asked me if I could run their $500,000 German still. I said, Sure, and by the second run we'll have a good estimate of the power, times to first drop, hearts, tails and quantity it will produce. By the tenth time you run it, you'll know everything necessary and it will be boring!"
I turn my power on. I learn what power it takes to get first drop in 1hour+45min
Start cooling water(s) at 1hour+30min
1+40 or I cut power to 60% and sneak up on first drop.
First drop, cut power to 45% and work through fores and heads at desired abv
COLLECT IN SMALL CONTAINERS
Adjust the power and cooling to get the desired abv as long as you can
COLLECT IN SMALL CONTAINERS
As the abv gets lower, and you can't maintain it, add power and collect the remainder as much/long as time allows. What turns out to not be drink can be rerun.

I have thermometers everywhere (boiler jacket, in the boiler submerged, in the boiler above liquid, at the top of the column above the dephlag and in the outflow of the product condenser water), because that's what came on a professional still. I had to plug the holes, so, yes, I put thermometers in them.
I rely one of them! Maintaining cooling water outflow below 140F is most important.
I have an old laptop on the wall. It has a stopwatch program running on it. I start stopwatch at power on and know within minutes what will happen.
The more automated you make the process, the more likely you'll try to ignore it, the more likely you won't know how or be ready to respond to anomalies!
I've had anomalies!
I've had a fire on top of a beer keg!
I blocked the bottom of a parrot, twice, and had product spewing out on the floor.
But, I was there watching.
After that, everything will depend on the quality of the ferment.
Remember, our ancestors did all this over a wood fire, by sticking their finger in stuff.
