Wireless data transmission protocol used for two-way communication between devices. Two-way communication means that each device can receive and send a signal. The system was created in 2002 by the ZigBee Alliance, which continues to be involved in its development and promotion. The main feature of the new communication standard is low power consumption and simple construction at low cost. This has been achieved and is now a fact. It has a range of approximately 15 meters.
The Zigbee Bridge gateway supports the Zigbee 3.0 protocol and uses the same eWeLink application and eWeLink cloud as other Sonoff and SmartWise devices based on WiFi and RF, making it a practical device for connecting Zigbee sensors with other smart WiFi relays and switches in a smart home or smart office system.
