ZigBee is being established as the leading wireless self-organising mesh networked, sensing and control standard for use in consumer electronics, energy, health care, home, commercial and industrial areas. Embedded into our Emerald range of products it is able to create a wireless grid communication network between all our lights and other Zigbee compliant consumer products. Scene settings and lighting fixture assignments to switches/ dimmers do not need any physical wiring as this is assigned wirelessly through the Zigbee system. In addition our Zigbee network will provide low level energy monitoring data so that users can make more responsible decisions about their energy usage.
