I have a client that has a home C-Bus network, and they wish to extend to pool area - the problem is that there is next no chance of running a c-bus cable to the existing pool area. My question is what sort of range is a wireless gateway capable of?. The house is double brick, and the pool area is lower than the house and about 10m away. There is a lot of concrete between the pool equipment area and the house. Was thinking of using 2 wireless gateways (1 inside house and 1 in pool equipment area), but I have my doubts whether the wireless will have the range and/or the penetration to go through the concrete. Appreciate your advice...
