Go to ‘More’ tab and tap on the Switches to configure the four numbered preset buttons. Tap on the Xpress and the configuration page opens. You can assign a scene, a group, a lamp or all lamps to each of the four preset buttons. You can also rename the Xpress to make identification more easy.
Please note that a Xpress switch can only control Casambi-enabled luminaires. It is not compatible with other wireless luminaires.
