Hello @taunushexe
as @ajb2k3 mentioned only one GPIO (the second one) is used for the RGB unit. So the other GPIO can still be used as input. I created an example which uses GPIO1 as input to control the color of the three RGB LEDs in the RGB unit.
See UIFlow2 Project Zone : M5Dial_RGBUnit_GPIO1_as_input_UIFlow2.0.4
Thanks
