The dusk sensor can be connected to the dusk input on the iX800 controller. If you also have a weather station or Internet weather, then you need to select which element invokes “dawn/dusk” in the system. Simply drag the box with the text “iX800” in the item dusk to the first position (if more than one box is available) to use the dusk input on the controller.

If you have connected your dusk sensor to a digital input, then you can select it via the button “add” and drag it to the first position.
