“YoLink” is a proprietary wireless technology provided by YoSmart. which is based on the Semtech's LoRa wireless technology combined with the YoSmart smart home/buiding protocol, to provide the most advanced smart home/buidling devices solution. Compared to WIFI, Bluetooth, ZigBee, Z-Wave, and other smart home protocols, it has the advantages of low-power consumption, long-distance coverage (wall penetration), and anti-interference. It is the first smart building/home protocol that can be very easily setup and is a very low cost but creates a reliable, robust and more secure IoT network.
