A Zigbee network is made of many objects which act as routers. Each of them will allow to extend the network range and make it more reliable allowing dialog of hundreds of devices between them.
Zigbee 3.0 is a radio protocol which allows a universal language between the devices, it is used by more than 400 manufacturers’ members of Zigbee Alliance. Devices using Zibee 3.0 can control lighting, HVAC, alarms, etc. It is a radio protocol well-known by the market and used by all types of companies.
The Green Power feature allows to integrate the use of energy harvesting technologies (magneto-resistivity, photovoltaic…) to the Zigbee stack, allowing to create battery-free devices. This feature is available for all products: controllers (wall switches, remote), sensors (temperature/humidity, motion, door opening) and also actuators (relay switches, smart plugs).
