KC-868-A4 0v-5v ADC no where near accurate
#1
Connecting the 0-5v generator to the A3 or A4 the ADC is reporting considerably lower voltages than what is physically generated and measured using a multimeter. 

Also if program an event using IFTTT using the ADC voltage to switch a Digital output it will not trigger the event?
E.G. IF AI3 is <=2.00v THEN DO1 to On  if I reduce the voltage to AI3 to less than 2.00v or even drop it down to zero volts DI1 output does not change state.

Dear Fleetz,

The ESP32's Analog to Digital Converter (ADC) has a resolution of 12 bits, which means it can detect 4096 analog levels. The ADC can convert input voltages between 0 and 3.3 volts into integer values between 0 and 4095.

You are using custom values, so there is no positive result.

Thanks for the reply.

Given the ADC is 12 bit with 0-4096 and accepting that the range is 0 to 3.3v which I was aware of at the time of posting I would expect the accuracy of the KSC monitor from my 0-3v would be extremely close. However it is not. The bit table to voltage therefore can not be accurate.

what KCS firmware version you are using?
after our new year holidays, i can test it.
