Smart Wireless Temperature/Humidity Sensor for Freezer, Fridge, Pet Cage/Tank Monitoring, App/Text/Email Alerts, Works with Alexa & IFTTT, 2 Pack with Hub

Our unique LoRa-based sensors differ from WiFi, Zigbee, Z-Wave, and most other wireless smart sensors in that they offer extreme long-range (up to 1/4 mile open-air), low-power (years between battery changes), and the ability to work outdoors, on other floors, and even in a metal box (like a fridge or mailbox)! Consider one of our weatherproof sensors, designed for outdoor use.

You can 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!

Make ANY fridge ECONOMICAL and SMART with YoLink smart sensors, saving thousands. Start with temperature sensors, then add door/lid sensors, leak sensors, and a Power Fail Alarm.

Enjoy PLUG, PLUG & PLAY convenience! 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!

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.
