It's a compatibility issue with the newer sensor firmware changes - hope to have it fixed soon.

Does this affects the CO2 measurement? Because I am seeing a large variance among them a few days after calibration (around 370, 410, 430, 445) but a rather small standard deviation within each (around 5 ppm, 1000 measurements over from 0 to 3AM)

Only a year late, but this should have been fixed in 04a6f85.
