⭐ ZigBee protocol

What distinguishes ZigBee from classic WiFi is a sufficiently long working time of battery-powered devices (unattainable with the classic WiFi protocol) and signal transmission through accessories powered by 230V.

In addition, selected ZigBee devices (230V mains powered) become part of the Mesh network. This means that if a module is unable to connect directly to the ZigBee gateway, it communicates with it through another closest accessory of this system. The repater in the ZigBee ecosystem are devices powered by 230V, such as PSMART, Aqara T1, OXT Zigbee relay, Sonoff ZBMINI, TUYA, 230V sockets or bulbs.

Thanks to this, you can create an extensive network that can operate over much longer distances than classic WiFi.
