The Green Power feature of Zigbee PRO allows battery-less Zigbee products such as sensors, switches, dimmers and many others to securely join Zigbee PRO networks. These devices can now be powered just by using widely available, but often missed sources of energy like motion, light, or vibration, to name a few. For example, Green Power takes advantage of the energy used to flip a typical light switch via common energy harvesting techniques, which is powerful enough send commands through a Zigbee PRO network.

How does Zigbee PRO Green Power feature work with Zigbee PRO networks?
By creating proxies in a Zigbee router device, each Zigbee PRO Green Power device is represented as always present on the Zigbee network – even when it is not powered on or present. These proxies forward and resend packets to ensure reliable communication, especially to destination devices, called sinks, that are not in the direct radio range of the Green Power device.
What makes devices using the Green Power feature of Zigbee PRO battery-less?
Zigbee PRO devices using the Green Power feature are able to complete communication with an average 100-500 ÂµJ (micro Joule) of energy. This energy is often created by capturing the energy used to flip a switch via common energy harvesting techniques including piezo-electric elements and dynamo/electro-mechanic converters.
What types of devices are ideal for the Green Power feature?
A variety of devices are well suited for lighting, HVAC, closures and energy management:
