I have a property that is very difficult for wireless (1m thick walls) but also very difficult to retrofit wired so I've had to divide it into several wireless networks. Whilst not all wireless receivers on a network are within range of each other (eg some switches) the wireless gateway I believe can hear all devices as it is more centrally located. All switches that need to control each other are in range . Is this actually OK in terms of topology (it seems to work fine) ? What would be much easier however is a C-Bus repeater or if the gateway could act as a repeater so that switch ranges could be near doubled... maybe even dual gateways used. I understand that the US range of switches / gateways do have repeater capability .. any solutions on offer for 230V 50Hz ? K
