No. The graphing software does smooth out data if your looking at a larger sample size like a weeks worth of data.
What's happening is the leaves above the sensor are blocking all the heat from the lights.
I have a sensor above and below the canopy right now. I'll post the results once I have 24 hrs of data.
This is the “Graph” function. As loaded on my laptop, it does offer more robust options than the cell phone screen, predictably enough, including export to cvs. I didn’t see a 365 day graph option, but I’ll fart around with it some more.
On the financial end, I’ve recently been building some related spreadsheets to break down & track rolling / monthly nutrient expense adjusted by reservoir size. I mean variable field for gallons rez, adjusts all individual nutrients (that I’ve selected) appropriately. Electric & gas graphed, year over year, with significant equipment changes noted. (420w T5 off, 1kw HPS on).
Kinda trying to tighten things up, all around. And I don’t recall who said, “If you wish to improve, first you must measure.” Anyway, that’s what one comes up with if one’s mind is like a sack of angry cats.
