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.

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 ?
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.

Werk,
The config file is correct, I have model A and have powered it down many times to no avail.
I have tried to copy the serial monitor output but with no success. Could you please explain how this is achieved
Regards
Jim
