ZigBee and ZigBee PRO networks are composed of several device types: ZigBee Coordinator, ZigBee Routers and ZigBee End Devices. Coordinators control the formation and security of networks. Routers extend the range of networks. End devices perform specific sensing or control functions. Manufacturers often create devices that perform multiple functions, for example a device controls a light fixture and also routes messages to the rest of the network.

This graphic illustrates an example ZigBee topology that includes one coordinator, five routing devices and, two end devices creating a control network. An example network in a smart home, the coordinator may be a home theater control system with advanced support for lighting and security. Devices such as light fixtures, thermostats and air conditioners could be configured as routing devices. Simple devices such as light switches and security sensors could be end devices.
