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

Ive got these temperature sensors scattered about. There are a couple places I worry about freezing in the winter, and its great to have a sensor in my greenhouse. The alarm went off the other day: it was 95 deg out and the temp in the greenhouse reached 105. Got a notification on my phone and went and opened a skylight. Nice to know I have those sensors watching over things! Also interesting to track humidity in my basement, particularly now that Ive added a dehumidifier. The whole system (hub, etc) works great -- really happy with it.

I already have a hub and 3 sensors. Adding 2 more was as easy as scanning the QR and pressing the button. I added one to my shop and the other to my greenhouse. Setting the temperature alarms was just as easy! I tried other temperature sensors and they just didnt have the transmission range. Battery life is fantastic! If you need to monitor temperatures, Yolink is the way to go!

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.

I bought this to place in the storage compartment of my trailer which I live in during the freeze in Texas (Dec 2022) so I would know I needed to turn on the heater to prevent my pipes from freezing. Worked perfectly. I would recommend this to everyone who needs to monitor any temperature. Easy to set up and easy to use. Yo link has the sensors needed for various items as well all controlled in one app.

This device saved me a lot of grief. I put it in the refrigerator and discovered the temperature was going up into the 40’s overnight. The digital fridge temp always said it was 37, so I wouldn’t have know there was an issue until the fridge conked out. I got the fridge fixed before it was a huge hassle. This device is worth every penny!

I have 2 sensors that track temperature and humidity. One is in our garage (tropical climate) and the other is in our refrigerator. I rely on the sensors when I am off premises. They are accurate and reliable. They have a strong connection to the WiFi despite one sensor being quite far from the hub (100+ feet). I have owned one over a year and the battery is holding up fine. Highly recommended product.

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!

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.

I did not have high hopes since I am expecting a device to communicate through block walls AND metal shed walls....BUT it is actually picking up a good signal! I am super impressed so far and I will continue to monitor and tinker with it this weekend. This device may have found a new home! Now I wish YoLink would make security cameras! You listening YoLink? Give us cameras! edited to add: This wifi hygrometer is amazing. It only lost signal one time, and thats when some guys installing a new fence for me cut my cable on accident. I was immediately alerted that connection was lost. I left work and pulled up to my house and asked why they cut the cable...they were baffled how I knew. lol I also sent an in app message to the developers and surprisingly received an email back within 12 hours.

These work great! Even inside my fridge and freezer! The display is big enough to se, and they work in the cold temps! Great to know when one of the kids leaves the basement fridge open!!!
