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.
Temperature Monitoring: Accurately track temperature levels with consistent updates to the YoLink app. Easily manage conditions in your home, greenhouse, fridge or freezer, barn, bedroom, chicken coop, dog kennel, plant nursery, or child’s nursery—anywhere you need reliable temperature awareness. Perfect for maintaining 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.
