YoLink devices don’t use your WiFi, ensuring no crowding or slowing down of your network. Instead, they operate with a unique LoRa-based, long-range, low-power wireless protocol. Place smart devices in areas WiFi can’t reach—outdoors, several floors away, in fridges, or beyond WiFi range! Using YoLink’s industry-leading technology, this sensor monitors up to 1/4 mile in open air.
