The ADC samples the Voltage from the potmeter and the "loading" can vary from mcu to mcu especially from brand to brand. If you like to have a steady reading, you must use a buffer circuit between the potmeter and the mcu to provide the Voltage to be meassured with a low impedance at the ADC input. ...

Hi I am fairly new to Arduino and ESP32. I want to have an AP running with an async Webserver, using Arduino, no problem, I found examples which are clear. Next, I would like to have the webserver to switch to an alternative page whenever a variable is set, e.g the ADC value is above a certain value...
