ZigBee - a stable network for a smart home
ZigBee is an energy-efficient wireless communication standard that works well in smart home systems. ZigBee devices can create a mesh network , allowing network-powered components to transmit signals further and extend the range of the entire installation. The SLZB-06mg24 adapter can act as a ZigBee coordinator, the central point of the network responsible for communication with sensors, relays, lighting, thermostats, and other automation devices. Support for Zigbee2MQTT and ZHA allows you to easily integrate multiple devices from different manufacturers into a single Home Assistant system.
