If some or all of your sensor values are missing, then your sensor may be unreachable (this will be indicated in the app). Please check the sensor batteries and replace them if needed. If only your carbon dioxide (CO2) value is missing, but the humidity and temperature levels are displayed correctly, then wait for 5-10 minutes to see if a measurement appears. The CO2 level is only measured every 5 minutes, and this may occur after a battery replacement.
If none of these actions have made the sensor values appear, then your sensor needs to be replaced.
Note: CO2 measures will not be displayed up to 12 hours after initial installation due to calibration of the sensor.
