@nestor89 in UIFlow2 you have to click on the square icon above the core that looks like 4 spall arrows expanding outwards to open the gui element options. If it’s for hardware/unints, you need to click on the + as if you were going to select another set of options
That is because the PIR sensor is a port B device (black connection and by default is assigned to PortB, however, when you select the Unit In Uiflow2, you have the option to change the port.
