What to Do If Multiple SwitchBot CO2 Monitors Show Different CO2 Readings?

• Related Product: SwitchBot Meter Pro (CO2 Monitors)
• SwitchBot App Version：9.4 or newer

1. Position the CO2 monitors in the same location, ensuring there is at least 1 cm of space between each device. Avoid blocking the ventilation ports.

2. Leave the devices undisturbed for five minutes. Then, press the button on the top of each CO2 monitor once to update the display.

3. Check the measurement tolerance.

The CO2 Monitor’s measurement tolerance is ±(50 ppm + 5% of the reading). For example, if Monitor A shows a CO2 concentration of 800 ppm, the acceptable range for the other monitors would be 710–890 ppm. If all readings fall within this range, the devices function correctly.

4. If the readings are outside the acceptable range, use SwitchBot App to calibrate the CO2 monitors.
