Hi Jim,
Can you please verify in your user configurable settings if the selected type of CO2 sensor is the right one for your sensor.
Have you tried to power off and power on again the AQM ?
Bear in mind that the new software only starts to try to read the sensor after an initial period of 3 minutes, and getting "wrong reply from sensor" on the first attempt of reading it may be normal.
If the problem will persist, please post a copy of the serial monitor output, it may help.

Code:
// --------------------------------------------------------------------------------------
// CO2 (MH-Z19) Settings
// Note: For outside use, the MH-Z19B model produces more accurate results
// --------------------------------------------------------------------------------------
#define Use_CO2 1 // 0= Not instaled, 1= Instaled
#define Z19_model 2 // 1= Model A, 2= Model B (ATTENTION: Make sure you select the correct model)Have you tried to power off and power on again the AQM ?
