C-Bus users now have a possibility to build wireless network as well as a wired. It might be needed when existing system is expanded and you don’t want to put additional cables. Currently only wireless switches, dimmers, scene controls and remote controls are available. Unfortunately there are no any security sensors or thermostats yet.
The switches, dimmers and scene controls are available in two styles – Neo and Saturn. Switches and dimmers can have two or four buttons. Scene controls – only four. To integrate wireless devices into wired system the C-Bus RF Gateway should be used. It provides a C-Bus protocol communication bridge between a single C-Bus RF wireless system and a single C-Bus wired network.
Wireless C-Bus devices look nice but there are two big disadvantages which limit their usage. The first one is small choice of available devices. And the second one is a range of transmitting of the commands. If I’m not wrong a wireless C-Bus device cannot re-transmit command sent from the controller via gateway. So, to improve a signal coverage additional gateway should be added. Comparing with Z-Wave or ZigBee where each device in the network can re-transmit sent commands.
But in any case, for existing C-Bus users the wireless devices can help extend their network without breaking walls.
