Jun 29, 2020· To change calibration modes and calibrate, go to Tasmota's Console and use the commands: Disable Automatic Baseline Calibration: sensor15 0. Enable ABC: sensor15 1. Calibrate in clean outside air: sensor15 2. This sets the baseline to 400 ( %), which sure isn't accurate but considered "good enough" for room air quality monitoring.
