When first pairing your Wave with your tablet or phone you will see your first measurements appear after approx. 1 hour.
The temperature and humidity sensors are ready to go! However, the radon sensor needs some time to calibrate and gather more measurements. The calibration period for the radon sensor is 7 days.
There is a countdown for the calibration period in the Airthings App as seen below:
+ 30 days recommendation
Although the calibration period lasts 7 days, we advise you to measure for at least 30 days, and ideally several months, before deciding whether any mitigation action is necessary. The radon sensor collects hourly air samples and is designed for long term measuring. This means the longer the measurement, the more data points, and the more accurate the long term average becomes.
