What exactly is Z-Wave and Z-Wave Plus?
Z-Wave is an internationally recognised wireless standard that has been developed by Sigma Designs and the
Z-Wave Alliance for home automation and adjacent outdoor areas and has been licensed for smart home ap-
plications worldwide. This wireless communication is optimised for low energy consumption and high commu-
nication security.
All available devices are certified on the basis of their interoperability within the Z-Wave standard. This makes
it possible to operate devices from different manufacturers and scopes of application in one shared wireless
network. Installations such as light switches, electronic door closers, heating thermostats, blind controls and
other devices such as sensors, wall switches and smoke detectors can be controlled via smartphones, tablets
and/or Internet applications.
Z-Wave devices can be powered by batteries or supplied from the mains. All devices connected to the mains
act as routers for all the other devices. If a signal cannot be sent directly to a receiver due to physical obstruc-
tions, the signal is automatically rerouted over other nodes. Within buildings, individual devices can commu-
nicate with each other over a distance of up to 25 metres, increasing to 100 metres outdoors. One advantage
is the 868 MHz radio waves, which are able to pass through walls with relative ease.
Z-Wave Plus is an extension of the Z-Wave standard, which includes all current further developments of the
technology. Depending on the product, this may involve a longer battery service life, faster operation, larger
coverage of the range and/or easier device installation. Z-Wave Plus devices are compatible with devices of
the Z-Wave generation
