environment of the residential house.

Average communication distance between two nodes is 100 feet (30 meters), and with message ability to hop

up to four times between nodes, it gives enough coverage for most residential houses.

The Z-Wave

interface may be added to almost any electronic device in the house, including devices that

were not meant to be “intelligent” such as appliances, window shades, thermostats and home lighting.

All Z-Wave-certified products “speak the same language” to provide true Z-Wave

interoperability.

A given device must be added to the Z-Wave

network before it can be controlled via Z-Wave

controller. This

process (also known as “pairing” see Appendix G on page 289) is usually achieved by pressing a button on the

device, an operation which must be performed once, after which the device will always be recognized by the

controller.

Devices can also be removed from the Z-Wave

network through a similar process of button strokes.

peripheral devices, the WeR@Home

Z-Wave

Controller is classified as a

The Z-Wave

Controller is the WeR@Home

™

system interface to Z-Wave

approved Smart Home devices

allowing control of such devices via the WeR@Home

™

system thus expanding the WeR@Home

™

system’s

capabilities and devices’ portfolio beyond Essence ECOP RF protocol capabilities.

The dongle connects to the WeR@Home

™

Central Control Unit (CCU) as an add-on.
