YoLink Yolink Smart Wireless Temperature/humidity Sensor Wide Range For Freezer Fridge Monitoring Pet Cage/tank Monitoring, App Alerts, Text/sms, Email Alerts, Works with Alexa Ifttt, 2 Pack- Hub Included

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.
