Understanding ZWave

What is ZWave

Z-Wave is a technology that uses radio signals to control compatible devices wirelessly.

From a controller (for instance a ZWave USB dongle), it is possible to control devices (such as switches, motors, bulbs…) and get datas from sensors (temperature, presence, contact…).

Look at the intro video in this web site: http://z-wave.sigmadesigns.com

Technical info

Z-Wave products are available in different frequencies.

Do NOT buy devices dedicated to another country!

The ZWave model

A ZWave network is a set of ZWave devices registered in a ZWave controller.

Get familiar with the terms below before starting:

  • Inclusion Add a Z-Wave enabled device (e.g. On/Off Module) to Z-Wave network.
  • Exclusion Delete a Z-Wave enabled device (e.g. On/Off Module) from the network.
  • Reset Restore On/Off Module to factory default.

Each ZWave device should be paired to the ZWave USB dongle. At this time, it gets a unique ID in this network called the node ID.

If 3 bulbs of the same type are paired, each will have a different unique node ID.

Up to 200 devices can be paired.

Each module is designed to act as a repeater. Repeaters will re-transmit the RF signal to ensure that the signal is received by its intended destination by routing the signal around obstacles and radio dead spots.

Direct association

A direct link can be made between a trigger (like a sensor) and a effector (like a switch). In this case, no smart behavior can be added between them.

ZWave devices

A Z-Wave USB Key is mandatory: The Z-Wave Aeotec Z-Stick Gen 5 USB Key

Then you can add Z-Wave devices.

Be aware that providing an easy to use experience needs dedicated code for each device. Thus, ONLY devices in the list below are integrated.
