Hi Zak,
Please check if the Temp / Hum sensor of the AQM board is working correctly, also make sure you are using latest software both in the RX and WD unit.
What AVR board version are you using?

All fixed
.The SHT31 temperature sensor was faulty and producing no output. Running the Adafruit SHT31 example code revealed the issue. I had not suspected it as the debug output of the CO2 sensor included a temperature value so I assumed it was working.

I really appreciate your speedy help and suggestions. Thanks.
