The problem is exactly this.
I am already using two inputs for the same ADS1115 and this cause conflicts.
If you integrate all 4 ADS inputs in PH/EC would be better, i think.
But i can solve it by using another ADS.
it also not possible set the number of measurements to average in PH/EC inputs.
I have another big problem, i don’t know if i should open a new post for this.
Using PH/EC input i can’t calibrate the probes.
Here is the voltages…
I don’t know, is it normal?
