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

Transmits from my shop building about 120 ft away from house and alerts me if temperature is getting close to freezing.

It was easy to setup and work really well, even from outside the house. The app is simple and straightforward. I was using it to monitor the inside of an egg incubator and it even kept working after the cat knocked the incubator over and it got covered in egg yolks. I am pretty upset but definitely impressed by this for the money. Hoping I can get the yolk out.

Easy to set up with yo-link, works as expected. Good range and quality

I started out using YoLink water sensors September 2020 (4 sensors w/ hub). Installed them in my finished basement and laundry and didnt really give them much thought until I received my first notification/alert, I was doubtful but immediately went to check and low and behold, I had a slow leak in a slop sink. These sensors saved me from a HUGE headache. I went and bought another 4 pack and have these sensors EVERYWHERE. Now that I have the water issues under control, I have started to work on humidity & temperature in my home with their sensors. Temp & humidity sensors are just as easy and accurate! These are great products and I look forward to what new products will be released next.

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.

Im usually skeptical with low cost devices, but I was in a situation to see if I needed to buy a new fridge, but wanted to know what was going on with it since it was starting to give me issues. So I purchased the temp/humidity sensor. Let me tell you, this system is awesome! The set-up was amazingly easy, and it was true to its word that it has a long distance connection. I have the fridge on opposite ends of my 2k sq ft home. It goes through walls and sends a signal to the (dedicated, sold separately wifi base) and provides me with notifications on my cell phone as I pre-set the qualifying conditions in which to notify me. Ive been talking to my friends about this unit. Highly recommend it.

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!!!

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!

Easy to instal - includes downloadable manuals and videos.

The YoLink temp sensors are great. They work well, are accurate and are super easy to install.
