To use the shading control, you have to add facades. A facade is an own control unit with controls its assigned blinds by cardinal directions.
You can add as many facades as you want under „settings“ - „shading control“. Preferably you add as many facades as outside walls you have. Usually there are 4 facades, which are configured with north, east, south, west or if the building is arranged diagonally the sun with northeast, southeast, southwest, northwest.
In the parameter panel of the facade, the direction can be set. Choose the best fitting of the 8 available directions. Assign your facade a name to order it easier later.
In addition to the direction you can choose a type. You can always add only blinds of the same type.
