I'm not sure if I'm using this right, I'm trying to disable the power to the research labs (and all their beacons really...) when running research. I'm not seeing a way to differentiate "0% of current research" vs. "not researching". I separated 2 labs to always run so they get it to 1% "gray > 0" but for REALLY big research (think late upgrades...) getting to 1% of 12k with just a few labs just to turn on the "big guns" is pretty hard.

Am I not using this as intended, or could we get something like "no research = -1, any research => 0"?

0% of current research should still output the name, so Anything>0 should be true when a research is selected.

I've now tried anything > 0 and gray > 0, both only seem to trigger once 1% (as far as I can see from the progress bar) is reached. In the code (and I'm NOT a modder), I see a math.floor being used, would that not send out a 0 until at least 1.00... was reached? So it won't be > 0?

floor() is only applied to the progress, because circuit signals can't have fractional parts. The research name string should output (as a collection of letter signals) on the next refresh (about 1s) after the research changes, then the progress signal will follow it once it reaches a number that can be reported.
