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

This product a bit confusing to install. But the extra time it took my husband to install is worth confidence in our 2 freezers accurate operation. We freeze fresh garden veggies and our summer salmon catch and a new beef. A product we are very happy to have and satisfied with absolutely.

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.

Our power goes off quite often, this system works really well to notify me of a power outage, or a rise in the temp if someone left the freezer door ajar. Twice now since I got this system, our power has gone out and my app notified me almost immediately! I’ve had this system for about three months now, besides the two therms the pkg comes with, I added one more so each freezer & the fridge are covered. So far, I’m impressed!

I bought this over 6 months ago and the batteries in the sensor are still near 100%. Setup was fairly easy. I use it in a deep freeze set at -10 degrees. Every once in a while I will check the app and see that the temp in the freezer is being maintained. Well it finally happened. Was away from the house and received a text and email notification that the temp in the freezer had risen above my preset +10 degrees. When i arrived back home I saw the freezer door was not completely shut. So the sensor and alerts worked perfectly and saved me hundreds of dollars of spoiled food. Highly recommend for the piece of mind it provides.

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)

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.

I have tried them all. This actually works. The temperature displayed on most freezer or fridges is not the actual temperature inside. This will fix that problem. And if someone leaves the freezer door open in a hot garage….this will let you know before it all goes bad. Truly a great investment. I needed you years ago!

In AZ, barely open garage freezers can become very costly. We have had to refill our entire vertical storage freezer twice this year and with 2 cooks in the house, theres lots of opportunity for mishaps. This has been a welcome solution. Pros - Peace of mind. - Once setup, has worked reliably without hassle. - Has already paid for itself several times over in saved food. - Clean app interface (although some unnecessary backtracking involved). - Alerts trigger quickly and loudly on connected devices. Cons - Mobile apps only, no desktop application. - More customization would be desirable. Notes - My observations are all made using Mac devices (iPads, iPhone, Macbook) - This is not a quick setup, should allow at least 1.5hr for setup, testing and customization. - Recommend do not try to setup wirelessly, plug hub into router during setup process. - Installed on my own, but they offer assistance if needed. - I keep the alert range set @ -10F -- +18F to allow for freezers to be loaded/unloaded without alerts (temps can be adjusted to 1/10 of a degree). - May be a good low cost alternative for small business owners. Overall, very happy with this system, the 2 sensors are monitoring 2 freezers in our garage and I will be ordering more sensors soon for indoor fridge and perhaps for terrariums/vivariums.

I bought this remote thermostat for my freezer. I didnt to loose a freezer full of meat. The thermostat is nice and small and just hangs from one of the shelves. Signal is great and with the app, I know the moment the temp drops below the alarm level that I choose. I also put one in the office where we keep guitars. This one has an alarm for humidity.

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.
