Wish I had this before our spare fridge died. Would have saved about $1000 in food. Works absolutely fantastic and super easy to set up. Highly recommend!

Easy to set up, comes with excellent instructions and so far so good. One strange thing, I watched someone on YouTube reviewing the sensors and he said they came with alkaline batteries but better if you use lithium AAA if using in a freezer ( better at low temperatures). So I switched to lithium aaa and the sensors went offline. Back to the supplied alkaline batteries, sensors work great in a freezer. Not sure why the lithium did not work they were standard ever ready lithium non rechargeables.

This was easy to set up and the temps are virtually the same as my Thermapen which has a certified accuracy of 0.5 F, and both of them read the same 1/10 degree temperature. It alerted me to a door that was left open, and it tracks the refrigerator temp well.

Easy to install hub and add devices. Really nice app. Notifications work really well. Especially like the real-time charts. Have ordered a bunch of other devices from this company I like it so well.

Very easy to set up and works even in a freezer that’s in the garage. Small price to pay compared to what a full freezer of meat costs to replace!
I just ordered another two sensors, one for the fridge and one for our rental suite. I can’t wait for YoLink to unveil their security camera option!

Bought this to keep an eye on my freezer. Pleasantly surprised when it came in overnight for ~45 bucks! At first I thought it would be junk but it wasn’t. Everything worked as it should, followed the directions on the app to get the hub hooked up to my wifi, and the sensors are as easy as pressing a button and scanning a QR code. It did take a couple hours for it to acclimate to the actual temp (was reading high for ~2 or so hours), but once it got to the temps in the places I put it, it was pretty consistent with my laser temperature sensor. Liked it so much I bought extra sensors.

I loved how easy the Yolink Hub as to set up (used Ethernet connection), and the App was easy to understand. Had no problems pairing and binding the Thermostat/Humidity modules with the Hub. Just scan the code on the modules from the App, and your off and running. The modules also displayed accurate values. Will be getting more modules, now that I see how nice this system is. Great product, will be expanding the smart system.

Using these monitors in my stand alone freezer and the other is in the freezer within the refrigerator. Both work well at those cold temperatures and provide a good strong signal with the hub. Easy to setup and the phone app is handy as you can program in alarm setpoints.

The ease of use on the app is incredible. I don’t know that they could have made it much simpler. A quick login and connect, as long as it’s semi near a router, the range is incredible. The quality feels sturdy, not cheap. It’s small enough that it’s not in the way, but accurate enough that I have no doubt that we would know right away if our freezer was going out. Overall, in the short time that we’ve owned this product, I’m very impressed with its performance.

I bought this to monitor my breastmilk freezer and it works well once set up, but setup was definitely not user friendly in my opinion. Maybe I’m not tech savvy enough, but it tool me awhile to figure it out and instructions aren’t straight forward. It is discrete in size though and great reassurance for me as I don’t want to lose all my milk! I think it’s a good price for what you get, just need better instructions. It seems to have a good range, I haven’t had any issues!

Lora wireless signal is more reliable than traditional Wifi.
Hub can be used to add all kinds of sensors from YoLink.
Using the temperature sensor in the freezer to make sure freezer is cooling properly.

I got one for my refrigerator and freezer and 1 for my freezer. Chest down the basement. So far, I can confirm that my freezer down. The basement is working well and the temperature is remaining at almost a steady minus ten degrees. My refrigerator was fluctuating and getting up to 44°. So I had to turn it down so I could maintain a cooler temperature for the refrigerator. It also has given me a few warnings for my freezer upstairs. That it has gotten up to ten point two degrees. Come to find out that when it got to 10.2. an ice cube was stuck in the ice maker door and was allowing air to go through the door. This seems to work pretty well and I like how it alerts you to the high temps. You are able to set the warning degrees to whatever you want. This is a pretty handy device.
