Eve Room will determine a room’s air quality by contrasting a certain tVOC count against optimal conditions. Calibrating the sensor requires that you place Eve Room in different locations; one with ambient conditions and another that is exposed to fresh air. After the initial setup, place Eve Room in its future location for about 6 hours, then move it to a well-ventilated area for 30 minutes. Repeat this calibration process if you move the sensor to a different room.
If you want to restart the calibration process, you 1st need to remove the Eve Room from your home, hard reset it and pair it again to Eve app in order to start the calibration mode.
