Nevertheless if the encoder board you're using also has its own pull-up that are stronger than ESP32's ones (which is likely the case), then there will be crosstalk between gpio, so you must bring Vcc. Look at your board schematic and you'll understand that these board pull-up create a "winning" pull-down when any other pin is grounded. +See also the "IMPORTANT NOTE" on the "Buttons" section + ### Buttons Buttons are described using a JSON string with the following syntax ```
