The first step is to add a picture of your room where the lamps are. You can take a new picture by tapping ‘Take photo’ or add existing picture from the photos in your device by tapping ‘Choose existing’.
After adding the picture to Casambi gallery you need to add lamp controls to it by tapping the ‘+’ sign. Select a lamp control of a lamp that is in the picture and tap ‘Done’. Now you have a lamp control in the picture. You can move it to the right spot by dragging and dropping and you can change the size of the control by pinching it with two fingers.
If you have more than one lamp in the picture you can add more lamp controls by tapping the ‘+’ sign. After you have placed controls over all the lamps that are in the picture tap ‘Done’ and you can control the lamps visually from the photo.
