xAll‑in‑one temperature intelligence for every space
YoLink’s Smart Wireless Thermometer uses a LoRa‑based wireless protocol instead of relying on your WiFi. This design reduces network traffic and lets you place sensors in places your router can’t reach—outdoors, across multiple floors, inside a freezer, or within a greenhouse. In open air, the signal can extend up to about a quarter mile, offering installation flexibility without sacrificing reliability.
With precise temperature sensing, the sensor feeds the YoLink app with steady updates so you can observe trends, compare conditions over time, and respond quickly when needed. Whether you’re safeguarding perishable items, maintaining greenhouse conditions, or monitoring animal habitats, you gain a clear view of how temperatures shift day and night.
