## Description

desertcart.com: YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range for Fridge, Green House, Pet Cage, App Alerts, Emails, Text/SMS alerts- Hub Required : Patio, Lawn & Garden

Review: Fantastic monitoring solution - I really like this set. It is easy to set up, works exactly as advertised and does an excellent of monitoring both my humidor and my wine cabinet. Humidity and temperature readings appear to be very accurate and sensors are very easy to read. I highly recommend this product at a great value/cost ratio.
Review: Gives me peace of mind - These sensors have been completely reliable in the five months I've had them. I've had a freezer door accidently left open by a kid before, which spoiled all of the food inside, wasting hundreds of dollars. With these affordable temp sensors, I have strong peace of mind knowing that I'll be alerted if something like that were to happen again! Battery life seems good so far. One of them appears full and the other close to it, so I believe them on their long battery life claims. They don't use some obscure battery size either, so that's nice. I use mine with the Home Assistant integration, which seems to be well supported. Being able to send customized notifications, toggle lights, or make smart home announcements based on these (and other YoLink) sensors is a major plus to me. Overall, I'm very satisfied. I'm not all-in on the YoLink system yet because I prefer to use Z-Wave/Zigbee for most things, but these seem to be a reliable alternative that is quite a bit cheaper, easier to pair, and has better battery life, while still not using WiFi for communication. The whole package is definitely enough to get me interested in investing more in their system.

## Features

- LORA > WIFI! 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. Put smart devices where you never could before: outdoors*, several floors away, in fridges, gun safes, and locations well beyond normal WiFi range! *Consider one of our weatherproof sensors, designed for outdoor use
- MONITOR & MANAGE your temperature and humidity concerns, whether it's a fridge, 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.
- IFTTT & Alexa Integration: trigger IFTTT applets based on high or low temperature set points reached (when device alerts). Voice query Alexa for the temperature (only; humidity not supported at this time). Triggering Alexa routines is not supported at this time.
- 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 one sensor provides you with 15 free SMS per month.
- 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. Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.
- BATTERIES INCLUDED! Two AAA batteries, good for 2+ years, are included!

## Questions & Answers

**Q: Can you have more than one temp/humidity sensor in the same house running on the hub and app?**
A: Yes, You can. One Yolink hub can support more than 200 YoLink devices in real test. YoLink Hub covers more than 300 feet indoor and 1000 feet in the open air. Normally one hub is enough for one house.
Hope this answer is helpful to you

**Q: How often does the sensor check the temp and humidity for automation?  Is the sensor only checked after a certain number of minutes?**
A: The sensor updates the app each hour, minimum, but also updates if any of the following occur:

At least 0.9 F degree change over a period longer than 1 minute

At least 3.6 F degree change within 1 minute

At least 5% humidity changes over a period longer than 1 minute

The device reaches a pre-set high or low alert level (set by the user)

Or the SET button on the device has been pressed

**Q: Does this work with smartthings and do i need the yolink hub?**
A: Sorry, YoLink system is not compatible with smarrthings now, YoLink uses LoRa protocol and YoLink Hub is required. Thanks!

**Q: I see the YoLink hub is required for all smart features.  Is there an alternate way to just connect wifi and monitor from ios without the hub?**
A: No, YoLink hub is required. YoLink smart devices use a special wireless technology based on LoRa, which can offer extreme long range (1000 feet compared to 100 for WiFi, outdoors, line-of-sight) and superior obstruction penetration including concrete and metal, but they do not use your WiFi. They need to wirelessly connect to one of our hubs. Thanks!

### ⭐⭐⭐⭐⭐ Works great. Long range. Easy setup.
*by G***M on January 18, 2026*

These work great. Have one sensor in the garage and one sensor in the basement and the base unit upstairs. The signal is strong for both sensors. The announcements are loud and clear from the base unit and the email and text messages to my phone are instantaneous with the announcement. The app info works great from anywhere. Great product.
