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

Easy wifi setup with hub. Add more in seconds. Very durable and accurate. I use these to monitor my freezers, fridge, and basement humidity. Will buy more as needed.

Works great. I can now monitor the temperature in my house wherever I am as long as I have internet.

I was very surprised how easy this was to set up. It worked in honestly about 2 minutes. The long battery life is a huge plus, and its quite accurate after testing it against known conditions. About 10 minutes after opening the box Id already bought more. My only VERY small complaint is no dark-mode in the App. This works great with Google assistant. I use it so I can ask what the temp is outside and get a real answer, not one for my area code. It integrates into IFTTT quite nicely. The temperature sensors are -not- wifi connected, to be clear. The hub takes Ethernet or links to Wi-Fi, but, the sensors dont.

Bought this to monitor the because it had a better range than other options. I needed to monitor the temperature/humidity in a coldfrrame in my garden. It’s down the hill from my house so I wasn’t sure if it would have the range I needed. Just pugged it in and set it in the cold frame. It works great! I think I will buy another for my small greenhouse in the same location!

I have 7 of these that I use. All but one seem to function with good accuracy. I have one that seems to be off from other thermometers by almost 5 degrees at times. Overall a good product with pretty good reliability.

These temp/humidity sensors took the place of my old Acurite hydrometers/thermometers. They were more accurate and now I have alerting through Yolink. Absolutely no issues with connection or distance. Have one in my gun safe too and the signal is very strong.

When used with YoLink smart hub this temperature and humidity sensor sends you alerts when your set limits are exceeded. Very easy to set up with YoLink ap and shows all device data on the ap. I place one sensor in my freezer and one in the house to monitor temperature at a glance from anywhere. Excellent system for peace of mind!

I am using this product to monitor the temperature in my chicken coop. I really only care about cold temperature to prevent frozen pollo. I was able to set up a cold temperature alert that goes to my phone. There is no history though, in that if you lose WiFi to the device it registers no temperature until your WiFi is back. I thought it would record the temperature at the sensor and update the app when it came back online. It is great for the price. It only updates in hour intervals so if you want to monitor something more often I would suggest another product or possibly another app could poll the sensor more frequently.

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.

Great trends in the app.
