## Features

- DON'T TRY THIS WITH WiFi! Our unique LoRa-based sensors are different from WiFi, Zigbee, Z-Wave and most other wireless smart sensors in that they are extreme long-range (up to 1/4 mile open-air), low-power (years between battery changes), and work outdoors*, on other floors, and even in a metal box (like a fridge or mailbox)!
- MONITOR & MANAGE your temperature and humidity concerns, whether it's a fridge or freezer, a barn or bedroom, a chicken coop or a dog kennel, a plant nursery or your child's nursery - anywhere! *Consider one of our weatherproof sensors, designed for outdoor use
- ECONOMICAL SMART FRIDGE! Save thousands when you make ANY fridge smart (or smarter) with YoLink smart sensors. Start with temperature sensors, then add door/lid sensors, leak sensors and a Power Fail Alarm.
- PLUG, PLUG & PLAY! Take advantage of direct ethernet connection and be online almost instantly when you plug your Hub into your router or network switch. Or, use hot spot mode to connect to your WiFi network in moments. Add devices in seconds using our Scan & Play QR code scanner in the app! Set your notification preferences, test your new sensors, then enjoy years of trouble-free operation!
- KNOW NOW! You have many options for being notified of device activity! Receive a text, receive an email, receive a phone push notification (including Apple phone "Critical Alert" severe weather/Amber alert type notifications that will activate your phone even if in silent mode. Android phones offer similar functionality, depending on phone manufacturer). SMS messages are limited to the total of 5 times each device plus 5. A hub and two sensors provides you with 20 free SMS per month.
