1.3 Technical Infomation
1.3.1 What is Z-Wave?
This device is equipped with wireless communication complying to the Z-Wave standard.
Z-Wave is the international standard for wireless communication in smart homes and
buildings. It realize a very stable and secure communication. Each message is
reconfirmed (two- way communication) and every mains powered node can act as a
repeater for other nodes (meshed network) in case the receiver is not in direct wireless
range of the transmitter.
Z-Wave differentiates between Controllers and Slaves. Slaves are either sensor (S)
transmitting metered or measured data or actuators (A) capable to execute an action.
Controllers are either static mains powered controllers (C) also referred to as gateways or
mobile battery operated remote controls (R). This results in a number of possible
communication patterns within a Z-Wave network that are partly or completely supported
by a specific device.
There are two different role a controller can have. There is always one single primary
controller that is managing the network and including/excluding devices. The controller
may have other function –like controllers don't manage the network itself but can control
other devices. They are called secondary controllers. The image also shows that its not
possible to operate a sensor just from a remote control. Sensors only communicate with
static controllers.
