The ZigBee protocol is a worldwide open standard providing low-power, wireless connectivity for a wide range of applications that perform monitoring or control functions.

The protocol is designed to allow devices to appear and disappear from the network, so devices can be put into a power-saving mode when not active. This means that many devices in a ZigBee network can be battery powered, making them self-contained and reducing installation costs.
