Iβll try to answer without looking it up:
When in normal mode (tiny torch off) if the signal entering the side is stronger than in the back than it releases no signal, otherwise it releases signal if the is signal entering the back.
When in subtract mode (tiny torch on) it will subtract the strength of the side signal from the strength of the back signal.
Also it can detect fullness of containers and states of multi-state things to emit a signal proportionately.

sorry
too relatable
I’ve learned just enough to sort of use it for automatic crafting benches.

As far as I understand it, maybe, is that it counts container values.
Ive been playing for 10 years and i also dont know and ik too scared to try
“how’s does” dude’s grammar is cooked
I like how nobody’s actually explaining how it works.

I hope I got this correct
