I’m fond of the CO2 Gadget too, but the autocalibration function takes 7 days to kick in, during which it must be plugged in continuously. This makes it impractical for use as a travel CO2 sensor when moving between two locations at different elevations. E.G., I had my Gadget calibrated for CDMX (2050m), then travelled to SF (50m) where the Gadget read 800ppm outdoors. I left the Gadget plugged in outside for four days, but it never calibrated before I left. I corresponded with an engineer at Sensirion who said it may be possible to add manual calibration via software update, and created a ticket for their product team. I hope they implement that.
