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 after my last freezer up and died an snow I am paranoid about my brand new freezer doing the same. The sensors are tiny and accurate and the set up was extremely easy. However, the notifications dont seem to be 100% reliable and this is the only reason I am taking a point off. It does not always tell me when my gateway is offline and without that, the temperatures are not being recorded/alerted if out if range. I occassionally get an email that my gateway is connected again but did not know it was offline in the first place. That is the omw concerning thing for me. That said, when my freezers go out if range i do get the notifications and can monitor them accordingly. All in all, a great budget solution that doesnt require further subscription fees (unless you want to upgrade)

Purchased this for our garage refrigerator / freezer after reading some horror stories about food spoiling because of not knowing the refrigerator or freezer stopped working. This took only a few minutes to set up and install. Integrated with the phone app after only a couple of tries. Adding the Alexa skill was easy as well. Now if there are any temperature excursions I get push notifications on the app and an email. I can also ask Alexa what the temperature is at any given time. Also, the 2 sensors (1 in the fridge and 1 in the freezer) have great wireless communication with the base unit which is inside the home in another room. Would recommend.

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.

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.

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 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?

Using to monitor temperatures in Kitchen and Garage freezers. Also purchased YoLink Water Sensor 2 and that is working as expected. The hub and sensors have a nice look and feel. Tested high and low temperature alerts and can say they are working well so far. The YoLink app on the iPhone looks clean and works well for me. Dropped a star because setting up the hub to my WiFi network was a challenge. The hub only supports 2.4Ghz WiFi and apparently the iPhone must also be on 2.4GHz WiFi in order to set up the hub to work on a secure home WiFi network. The iPhone kept connecting to 5GHz by default and could not complete the hub setup step. Since 5GHz signals have a shorter range than 2.4GHz, I solved it by taking hub and phone to far end of house where I had a weak WiFi signal. Was then able to setup the hub to our WiFi.

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.

First, setup was very easy. After calibrating all of the sensors (I have 7 total) I put one in each room and one outside. I can now check the temperature in each room from anywhere. Theres only two issues Ive had so far. 1) after setting up the hub, it downloaded a couple hundred GB of data from the internet. I checked the firmware for all of the sensors and the hub but they were all up to date. Id like to know what all that data was for. 2) it works with Alexa... as long as you only want to know the temperature. It doesnt show the humidity and you cant use it as a trigger to turn on the dehumidifier when the basement humidity gets to 45% or to turn on the fan when the room gets to 74°F, for example.

Our Toddler turned our deep freezer off, and we didnt know because it was still plugged in and the light was on. But we lost alot of food and so we purchased these for both our deep freezers. They work great and I love it syncs up to our phones and we can monitor everything on there.
