Smart Wireless Temperature / Humidity Sensor Wide Range (-22 to 158 degrees) for Freezer Fridge Monitoring Pet Cage/Tank Monitoring Smartphone Alerts, Works with Alexa IFTTT, 2 Pack - Hub Included

These sensors work amazingly well even inside your freezer. The supplied hub plugs into your router and receives a solid signal from each of the included sensors. Our freezers are in the garage. I have them packed with wild game and other expensive meats. Loss would be catastrophic. These sensors send a solid signal and alert me on my phone when the temps enter dangerous ranges. So far they have worked flawlessly. Cheap insurance.

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!

We have a refrigerator out in our uninsulated garage. I wanted to monitor the temperature for 2 reasons. ONE, during the winter I want to ensure temperatures are maintained. TWO, this is an old fridge, so I want to be alerted if it stops working altogether. I love that these monitors collect a history so that I can easily keep an eye on things. I found the setup to be very easy and quick. I connected directly to wifi using my Eero system. I love that there will be alerts sent directly to my phone so that I can take action ASAP. I just installed this today and I will absolutely update my review if anything changes.

I have two of these. One placed in each of my deep freezers. They have been online for a year in a zero-degree environment without an issue. Yolink is unique in that they have a long-range and each sensor doesnt add another wifi radio to my house. Yolink also provides the ability to receive text messages as well as notifications through their app.

This works well to monitor fridges or freezers. I set the range that I consider good and get alerted when it’s exceeded. Does exactly what I wanted as I don’t have to check on the freezer and can see temps and alerts even when not at home. The app could be much more intuitive than it is, but once you figure out where everything is, it’s fine.

I had recently placed a negative review of this product. However, after more attempts, we DID get it to work (via cable) and so far it is working well. I really WOULD recommend, though, that your modem has a free plug-in place. That was our problem before; getting it connected Wi-Fi can be a challenge. For now, I have freed up a place on my modem to plug in the hub, and getting the device set up and working took a little bit, but now it seems to be working fine.

We are currently using in a k-12 school system to monitor all our coolers and Freezers. Easy installment. App is easy to use. 24 hour monitoring with text, app alerts and email alerts. Economical! Highly recommend! Have not needed text support yet.

humidity readings are off, i can put the same unit side by side and 1 is 83.5 humidity the other 79.3. always 3-4 degrees off each other, temp off but by 0-1.5 degrees... i think humidity reading are higher than normal, since my other units read humidity 5-8 degrees lower constantly BUT i dont know which is the accurate reading! I dont get the email alerts when reading are above threshold which is cool, but still returning,

Love having these in the freezer for piece of mind. We have had freezers go bad before and lose everything. Decided to purchase these before we bought half a side of beef. Easy to hook up and install to router. App works great, easy to set temperature ranges. I get notifications if it goes above or below set temperatures. So glad they make these now.

You cant go wrong with these sensors. They are easy to program and have a long range. Tech support is great too.
