I need to set up a sensor network for an hotel. Each room will have a central node + some RF sensors + some RF actuators.
I would like to do a point-to-point communication from the sensors to the central room node, a point-to-multipoint communications from the central node to each actuator, and a mesh among all the room nodes and the Internet gateway.
I know what modules I need to use to implement each of these topologies, but I don't know what to use for implementing all together.
For sensors and actuators, I would need a basic XBee module or XBee PRO.
For the Internet gateway I would need the CONNECTPORT X4.
But what do I need for the central room node? It is possible to implement this network using only one XBee module for the room node? Or do I need to use more than one?
Thanks in advanced,
