Since the Inputs A1 to A4 have an internal pull up resistor the analog voltage should read 3V when the input is open. For some reason I am unable to read the voltage of a open input and it returns 0.075V.
Am I correct that the reading should read around 3V because of the internal Pull-up resistor?
The input config is:
sensor:
- platform: adc
pin: GPIO14
name: "Analog Input A1"
update_interval: 5s
What am I doing wrong?
