When will this be possible? The current adc example only reads ref/gnd and the library has no access to the 4th input. I am looking to use my analog co2 sensor with this.

Our ADS1015 library is very strongly (probably mistakenly so) biased toward our ADS1015 breakout which includes an onboard reference connected to input 3. Thus the name ref/gnd being erroneously used in the library.

ref is actually just AIN3, and on Enviro+ this is connected via a 330Ohm current limiting resistor to the ADC breakout pin.
