You can connect the rain sensor to the appropriate input of the iX800 controller. IF you also have a weather station or Internet weather, then you need to select which element invokes “rain” in the system. Simply drag the box with the text “iX800” in the item rain to the first place (if more than one box is available) to be able to use the controller’s rain sensor input.

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