What is Z-Wave routing and how does it work?

Source routing

Source routing is a method of routing that allows for the Z-Wave controller to specify the path a signal will take on the network. The Z-Wave controller has a memory of the network topology (i.e., the layout of the network), so it can determine the best path for a command to take based on which node is the signal's intended destination.

Static mesh network 

In a mesh network, the nodes on the network are able to route commands to other nodes (i.e., nodes are able to act as repeaters for other nodes).

In a static mesh network, Z-Wave devices are expected to not move from their normal locations. Since the Z-Wave controller can remember the network layout and send signals based on node location, it is important that Z-Wave devices remain in the same place. If a node needs to be moved, perform a network rediscovery after the move.
