Innovelli's button mapping uses presses for up and holds for down in their version of the driver. Use the built-in Innovelli Smart Scene Dimmer driver it uses more common sense buttons but doesn't support as many taps, and the advanced button controller app to map out the functions to the buttons.
If you need to make an adjustment to a function that the built-in driver doesn't support, then you can switch back to the Innovelli provided driver to make the change. Hit configure then move back to the built-in one.
In this use case I am using the button presses to control some smart bulbs but you can put whatever you want in there.
If you just want to control the load then make sure it's configured for that in the custom Innovelli driver then switch back to the built-in driver. You can forgo the ABC controller for local load control.
