You are not making this any clearer unfortunately ....which is it
"The ESP reports 0-1023 to correspond with 0V to 3.3V." or
"The ESP reports 0-1023 to correspond with 0V to 1.0.


Sorry, my mistake.
The ESP reports 0-1023 to correspond with 0V to 1.0V.

Good O , that is unusual for me with only an Arduino background .
So now I'm tossing around the use of the ADC with the .readvdd33() function and what is actually being read there then.
