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

We have one in each freezer and our refrigerator. The app works great, very user friendly. The hub has a good distance for the sensors. We have our freezers in a separate building behind our house and it reaches no problem. The peace of mind being able to check your freezers while on the road is worth it.

Be aware of what you buy. An other brand I bought only works on Bluetooth so you only have phone/app readings when you are near them. But this product works on wifi, so you can access them anywhere thru an app on your phone AND get phone alerts for temperature or humidity. The charting/history granularity is one hour minimum however alerts can be set for a minimum of 10 minutes. That all said if you wants alerts because of a power outage, then your wifi may be out also so you would not get alerts or readings without some backup power source. The units are battery powered and with a battery status icon on the app. The hub unit plugs into ac power. It can be set up via cable to a router or via your wifi network.

Took me less than 5 minutes to install three sensors and a hub - start to finish. I have two leak sensor and a temp-humidity sensor. Next, I am going to get the garage door sensors and controllers for my three car garage. Absolutely impressed by having zero software or hardware glitches compared to hours of headaches with prior home automation devices. Should cost a lot more for this quality of product!

I can leave my house and know in an instant whether or not my heating system is working properly after having had problems in the past. Great product. Excellent price.

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.

This could not have been any easier to set up. Took ten minutes from opening box to sensor in freezer sending readings. Signal from freezer sensor in garage to hub in living room is full strength. Highly recommend

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!

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.

Very solid construction and feels heavy/durable. I have only had for a month but battery life is expected to be very long. I use this to monitor my fridge and freezer temp because I was having issues. The temp monitoring isn’t real-time, but I believe it updates every 5 mins. Easy to connect to your router with supplied ethernet wire. I believe there is a wireless option but I havent tried it yet. I bought the one with the provided hub. You can monitor your temps and humidity from anywhere in the world using the app. Very happy with the product. Will buy again for future applications.

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.
