YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range (-22 to 158 Degree) for Freezer, Fridge, Green House, Pet Cage, Smartphone Alerts - Hub Required

Good quality products that are easy to setup and work properly right out of the box

The Yolink temperature sensor is essential in promptly detecting temperature excursions in any location. We use one on the refrigerator, and one in the freezer. While these sensors do not integrate with Alexa, the Yolnik app can be programmed to send email and text messages when temperature limits are exceeded.

Great trends in the app.

My freezer

Love having an App on my phone to check my stand up freezer temperature wherever I am at. Took a bit over 10 minutes to set up. Well worth the sense of security knowing that my food is safe

I was looking for a system to monitor my home while I was away. After doing hours of research I selected the YoLink solution because, for my needs, it offered the best combination of available functionality and simplicity/reliability. The system connects to the internet using a small hub device. The *many* available monitors and sensors connect wirelessly to the hub using LoRa wireless technology, The LoRa wireless operates on a different frequency than home wifi and offers greater range. It easily penetrates walls and floors. All of my monitor/sensor wireless connections located in 3 levels of my home and garage are rock-solid. Setup is unbelievably simple. First install the phone app. Then setup the hub which can be connected to your home network wireless or hard wired. To add devices to the system, simply scan the QR code label on each sensor using the app and it will be added to your homes system. Thats it! I am currently using this for temperature/humidity monitoring, water leak detection and garage door (open-closed) status right out of the box. I havent yet tried programming which can add additional functionality. Using the apps notification features I can get alerts,etc on my phone and even on my Apple watch over the cellular network. I get all of this for a reasonable price. BTW, for video monitoring, I use Blink cameras. Using both systems is not cumbersome or inconvenient.

I purchased three of the YoLink Humidistats to run 4 brand new humidifiers. I bought them to start this frigid, dry air, winter. Thats One YoLink Humidistat on Two Humidifiers in the Great Room (Living Rm, Dining Rm.) and they run better than I could have ever expected using the YoLink Humidity Meters. Im also running One YoLink Humidistat in the Kitchen and Master Bedroom, each Running one humidifier in each room. This takes total care of the first floor of my home. Its so comfortable now, I cant say enough. They start when humidity gets below 45% and shut off when humidity gets above 50%, restart at 45% and again stop at 50%, thats 24x7. Start and Stop humidity levels are up to you. So Good I bought and am waiting enough to do second floor. YoLink has been so easy to set up. All their devices are about two steps to get you on the YoLink app. Once you see them on the app, you may need a few tips with support because they do so much. Give them a call like I did on my first humidistat and Ive set up the rest by myself.

Pros: Easy to install, communicates with rest of Yolink integrated system, can provide voice warnings when used with a speaker hub. I purchased two thermometers that I wanted to integrate with the rest of my Yolink water leak detection and shutoff system along with my speaker hub. Installation was a breeze, scan the qr code, push the set button, and you are in. Because I have a Yolink speaker hub I was able to program the thermometers to issue a voice warning when the refrigerator temperature went above 42 deg. F (the high and low temperature limits are programmable). Programming is very easy and intuitive. Without a speaker hub, users will receive an email and notification and, optionally, a text message. Customer service is excellent. Batteries are supposed to last two years or more and the Yolink app shows the battery status of all components. When compared to a calibrated digital thermometer, the Yolink thermometers were well within one degree of accuracy. As a bonus, the thermometer keep a history of temperature and humidity. These thermometers are designed for indoor use. Very pleased with this product.

Wow that was Easy press that button on the back to turn on sensor and setup in app. Of course setup the Hub first. Create and account after connecting Hub.. I connected my hub directly with network cable. Hub does support wifi connection to your network. Once Hub is powered up in app just click the Add icon upper right, enable app to use camera and scan QR. Next click the Add icon again to add your sensor scan QR on sensor and well did I say it was easy. Next go to your Alexa app and go to Skills and add Yolink and Enable and link your account. No need to scan for new devices in Alexa. Just say Alexa what is the temperature on the Themperarure and Humidity sensor you can change the name of the device but ha that was so easy. Did I say it was easy...
