Comment Comment by emmanuel_1234 I unplugged my AirGradient a couple days ago. It's quite the useless piece.The CO2 sensor does not read CO2 levels, and recalibrates automagically. I have completely wacky readings from it, from 200ppm to 2000ppm.The VOC sensor also apparently does not read VOC levels, see discussion here: https://forum.airgradient.com/t/measurement-values-for-the-a....All in all, I'm frustrated I fell for the regular free advertising they get on HN. parent emmanuel_1234 2 years ago
