After power cycling my AirGradient ONE, I am no longer getting and PM, NOx, and VOC measurements. CO2, humidity, and temperature are fine. I saw a brief message on the screen as it booted up saying that the SGP41 was not found.
I’ve power cycled it several times, and I get the same results. I’m on the 3.6.0 firmware.
Any ideas, or did the sensor go bad?

I left it unplugged for a couple of hours and plugged it back in, and the error went away. I’ll keep monitoring this, and if it repeats again, I’ll send in the logs.
