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

I bought this because we have a stand alone freezer in our basement. We had an instance where the door was somehow not closed all the way and we lost a lot of food. I had been searching for a device to alarm us if the temperature dropped in the future. Im an old guy and did have a couple of snags in initial setup, totally my inability toread directions. I attribute that to being a man! Thankfully the support I received from YoLink was the best support I have ever received for anything I have ever bought. Thanks to the guys at YoLink, I have an up and running unit connected to Alexa as well! Thank you!

We have a lot of meat in our freezer and this is a great tool to monitor and be alerted if the temp gets too high.Sometimes those kids forget to close it all the way or if the power goes out in the garage and we dont know it. Plus if you are out of town, someone could come by and save all your frozen stuff for you. Set up was easy as long as you plug it straight into the router. Did not try the wifi method.

Easy to install. Alert works.

I bought this because my freezer got left open and I had to throw away several hundred dollars worth of food since it spoiled. Today the freezer got left open yet again (I think the magnets are going bad) and I was notified within 40 minutes of it being left open. We had just completely restocked our freezer and would have probably had to throw away close to $800 worth of food. This system was insanely easy to setup and was probably the easiest thing Ive setup in years, the temperature readings are accurate to 1 degree or closer, and for the cost its just a no-brainer. The thousands of dollars this system is probably going to save me over the years is worth the cost 10 times over and then some. I couldnt recommend this system more and if youve ever left your refrigerator or freezer open and wasted food I wouldnt even hesitate to buy this system!

We needed these for years, didn’t even know they existed until after we had bought a wireless cooking thermometer. We have had so many items get thawed out because someone didn’t completely shut the door on the freezer in the basement and even though it has an alarm it is so soft we can’t hear it. The only one who seems to be able to hear it is my daughter. It can be going off and she’ll hear it but I can’t. This system actually hooks up to your Wi-Fi and will alert you via text if your temperature falls outside of the ranges you program for it. At first we were getting alerts a lot but since then were able to adjust the range to where we haven’t had an alert since we first got it. You are also able to monitor the temperature using the app. Very happy with purchase.

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?

I have 4 of these devices in my house. I’ve had a few issues setting these up. Customer Service has been exceptional in guiding me through the process of completing the setup. I highly recommend this product and company.

The product is easy to install. Long range and communicates well with app and hub even though the sensor is in the garage in a freezer. Awesome

Very impressed with this product. Super easy to set up, slick app, sensors are accurate. If anything goes wrong will update but happy at the moment.

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.
