Current value of gain: 00h = low gain (1x), 10h = medium gain (25x), 20h = medium gain (428x), 30h = high gain (9876x).
To use the node in your project you should have the wayland/tsl2591-light-sensor library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
