A network is used to control Casambi enabled luminaires and share settings between them. Even if you have only one luminaire you need to add it to a network before you can control it with Casambi app. Later you can add new luminaires to the same network to control all your Casambi enabled luminaires easily from the ‘Luminaires’ tab in the Casambi app. The luminaires that are in a network form a mesh network which means that it is possible to control all of the luminaires in that network if you are in the range of even one of them.
