    I must be honest and say I was a bit skeptical about this product at first (placing a wifi device inside a sealed metal box), but let me tell you, it really works! Once you get the thresholds set it will send you a notification directly to your phone (via email) when the temperature or humidity has exceeded your setting. Be mindful of your defrost cycle. It will send false readings if you have your threshold set to low. Once I got that figured out, it has worked flawlessly. You can monitor it in real-time via a graph in the app. Super impressed with this little device. It definitely gives peace of mind that my freezer packed with venison will be safe and sound on my next hunting trip.

    I had to have my Nephews kids set up for me, as its too much hassle for. I got one sensor in basement freezer, and one in upstairs freezer, and they both get out. My problem is all the false alarms. I set mine to 20°, and my analog gagaes dont show that temp. Another more important thing is if its hooked up to wi-fi how much snooping is going on?

    We have one in each freezer and our refrigerator. The app works great, very user friendly. The hub has a good distance for the sensors. We have our freezers in a separate building behind our house and it reaches no problem. The peace of mind being able to check your freezers while on the road is worth it.

    Temp/Humidity sensor easy to set up. Had no real trouble getting system up and running. Took another thermometer and placed it next to the YoLink T&H sensor in my refrigerator and the YoLink is off by about 2 degrees. With all that said the 2 degrees calls an alarm because the range of temps for the fridge is 34 to 38 degrees F I even dropped the operating temperature and increased the alarm high a degree or 2 and I still get a lot of notifications. Next I tried to calibrate the sensor in the app, changed the calibration by 2 degrees and saw not change in the reading. I really wanted the sensors so I can monitor the temperatures the warning is a bonus...if I can get it to calibrate.

    We buy meat in bulk from a friend that has a connection to the farm. We store the bulk meat in a freezer in the garage. My problem was my children were opening the freezer to get something, a popsicle or something and occasionally the freezer door was loosely shut. This allowed the heat from the garage to come in and defrost the meat. On one occasion the meats blood was leaking out of some of the meat packages, ice cream was destroyed etc. So I purchased to put inside the freezer. You have to buy that hub, but is the easiest thing to install. I downloaded the app, created a login, took a picture of the bar code on hub by the app, hooked the hub up to the router, its done. Set up the thermometer by taking a picture of bar code in the app, its done.

    My fridge/freezer starting showing signs of failure so I bought this Yolink device to monitor them and get notified of issues. IT JUST WORKS! Simple to configure, works reliably, and does exactly what it’s designed to do. I especially like the flexibility in alarm settings and also alert settings. I would absolutely recommend this product to anyone. It’s worth every penny!

    Using these in my Samsung refrigerator/freezer, and what a wealth of information. now I can see when it goes into defrost mode, how often it does, and even how much of a temperature drop occurs in order to make ice. excellent devices for monitoring fridge and freezers. Will be ordering more devices for other needs. New fan here.

    Excellent range and performance. I had spent over $150 for another sensor and even bought a range extender to try to get temp from a freezer downstairs but it still couldnt pick up signal. Returned those items and ordered Smart Wireless Themometer and water sensor for much less money and was surprised to see that all those great reviews were correct. It has great range and works flawlessly. I even bout a second system for my second home. It even picked up the signal when I tried the sensor in my next door neighbors freezer. Both systems, plus 3 extra water sensor, were still cheaper than the orignal system and extender I had returned

    I bought these to monitor the temperature in my pump house and in the freezer in my office. This device works perfectly, and exactly as I hoped it would. I had to call customer service for some assistance in setting it up, and they were very helpful.
