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 Monitoring: Keep track of temperature 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 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. Triggering Alexa routines is not supported at this time.
  • Commercial-Grade Accuracy and Wide Environmental Range: Designed for precise environmental monitoring, YoLink Thermometer delivers temperature accuracy of ±0.36°F (32°F to 129°F) and ±0.72°F (-20°F to 32°F). It measures temperatures from -4°F to 129°F (-20°C to 54°C), 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.

Other sensors I tried did not have reception inside the freezer. Only outside with a wire breaking the seal to have antenna outside of freezer. Works very well in home assistant.
