with Z-Wave-certified devices from other manufacturers. All
non-battery-operated nodes within the network will act as
repeaters regardless of manufacturer to increase the reliability
of the network. On delivery, the device does not belong to any
Z-Wave network. The device needs to be added to an existing
network to communicate with the other devices within it.
Devices may also be removed from a network. The add/
remove processes are initiated by the primary controller of the
Z-Wave network.
