About this item

  • LORA > WIFI! 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, gun safes, or beyond WiFi range! Using YoLink’s industry-leading technology, this sensor monitors up to 1/4 mile in open air.
  • Real-time Temperature & Humidity Monitoring: Keep track of temperature and humidity levels with high precision, continuously reporting real-time data to the YoLink app. Manage your environmental conditions whether it's in your home, greenhouse, fridge or freezer, barn, bedroom, chicken coop, dog kennel, plant nursery, or child's nursery—anywhere you need it! Perfect for ensuring optimal conditions across a wide range of locations and uses.
  • Customizable Alerts & Notifications: Stay informed with multiple alert options! Set custom thresholds for temperature and humidity, and choose to receive alerts via text, email, or push notifications. Apple users can bypass silent mode with "Critical Alerts," while Android offers similar options. SMS messages are limited to the total of 5 times each device plus 5. A hub and one sensor provides you with 15 free SMS per month.
  • Battery-Powered with Extended Lifespan: Powered by two AA batteries, the sensor delivers up to 5 years of continuous operation, depending on usage and environmental conditions. Receive real-time low battery alerts via the YoLink app, ensuring you're notified when it’s time for a replacement. Designed for convenience, its long-lasting battery life minimizes the need for frequent replacements, making it perfect for hard-to-reach areas and critical monitoring applications.
  • IFTTT & Alexa Integration: trigger IFTTT applets based on high or low temperature set points reached (when device alerts). Voice query Alexa for the temperature (only; humidity not supported at this time). Triggering Alexa routines is not supported at this time.
  • Commercial-Grade Accuracy and Wide Environmental Range: Designed for precise environmental monitoring, YoLink Thermometer Hygrometer delivers temperature accuracy of ±0.36°F (0°C to 54°C) and ±0.72°F (-20°C to 0°C), and humidity accuracy of ±3% (10%-90% range). It measures temperatures from -4°F to 129°F (-20°C to 54°C) and humidity from 0% to 100%, ensuring stable performance in various environments, whether in cooler temperatures or warmer conditions.
  • HUB REQUIRED for full functionality, including for the app to work, but your hub is compatible with a growing family of smart products for home and business! YoLink devices do not use your WiFi, they do not crowd or bog down your WiFi network, but instead they use a unique LoRa-based extreme long-range and low-power wireless protocol unique to most of the smart home industry. Search for B09FSS95G9 for a SpeakerHub, B07TQLKQLJ for the original Hub, B0DCBSPP7L for X3 Hub.

YoLink is far superior to all competing technologies (e.g. ZigBee). Built on LoRa technology, it has the best range and battery life of any alternative system. I am using dozens of sensors at multiple locations. I have also linked with Ring and Alexa for additional automation. Great system!!

Works great. One of these will live in the freezer, one of these will live in the refrigerator. So if we lose power while we are away we will know whether we need to throw everything away. These are perfect for that application because there's no display on it. Don't need one since it's going to be sitting in the dark in the freezer anyway. Very easy to set up.

Fast, easy integration into my Yolink group of devices - takes about 10 seconds if you already have a hub (needed) and maybe some devices deployed. Just scan the device's QR code from inside the app, give it a name, and you're done.Accurate and long range. I'm using it to monitor a basement fridge. As with all Yolink sensors, options for alerts and alarms. Well thought out system, I really like my setup using the Yolink infrastructure.

I had multiple Yolink X3 thermometers. One problem is that the refresh rate is very low, in order to prolong battery life. So the only reason I purchased it is because the real-time claim in the description: "Real-time Temperature & Humidity Monitoring: Keep track of temperature and humidity levels with high precision, continuously reporting real-time data to the YoLink app". Well, this is completely not true. In fact, just like all other Yolink Thermometers, its typical refresh frequency is 1 time/hour. It also refreshes based on how fast temperature/humidity changes. Perhaps what it means by saying real-time is that you could press the SET button to refresh temperature reading. But then this item is no different from other Yolink thermometers. All X3 thermometers have the SET button but their product description never mention real-time reporting.

I use the thermometer units to monitor a freezer and refrigerator. Quite accurate compared to a lab thermometer - within 1 degree. The products including their app are well thought-out, and tech service is best I’ve seen. I wish all companies were as good.
