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 used the thermometers in my fridge, freezer, chest freezer, top floor, and basement. I like being able to get alerts and keep track of temperatures and humidity to make sure everything is in working order. After almost a year the hub would like to disconnect fairly often, but I sent a message to yolink and they were able to send out a new one for me. They seem to be very easy to deal with and their products overall have been nice to have around.

We buy meat in bulk from a friend that has a connection to the farm. We store the bulk meat in a freezer in the garage. My problem was my children were opening the freezer to get something, a popsicle or something and occasionally the freezer door was loosely shut. This allowed the heat from the garage to come in and defrost the meat. On one occasion the meats blood was leaking out of some of the meat packages, ice cream was destroyed etc. So I purchased to put inside the freezer. You have to buy that hub, but is the easiest thing to install. I downloaded the app, created a login, took a picture of the bar code on hub by the app, hooked the hub up to the router, its done. Set up the thermometer by taking a picture of bar code in the app, its done.

I dont write a lot of reviews, but this one deserves my time to do so. We have a freezer in our garage, and for whatever reason, the door has been left slightly ajar a few times. And there we are with probably $75 of food that probably should be thrown out. So I went looking for a solution to let me know when thats happened. The YoLink is working great, and has already notified me twice that the freezer door was ajar (temperature rising). Our network router sits in a closet in the middle of the house, and the YoLink hub is plugged directly into that with the supplied ethernet cable. Then the YoLink sensor is in the freezer. It has no problem connecting with the hub through 4 walls and the freezer door. My only outstanding question is whether the sensor batteries will last very long. But still this product is well worth the money spent.

I use one sensor in our fridge and the other in our beer fridge. They work beautifully and accurately. I simply check the app when I want to know how cold they are. I also set up alerts if they get above a certain temperature guaranteeing no spoiled food or warm beer. Its extremely easy to set up ythe app is user friendly. I highly recommend this product.

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?

Got two temperature/humidity sensors for a second home to alert us if Temp gets too low. Easy to set up. Batteries last a very long time. Smart phone alert system notifies me if Temp is too low. Product support is great. Works over long distances. I use this system in two locations in two different states, both operating through the same app, no problem. A+ rating!

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.

The YoLink app is simple, easy to use, and very straight forward. Pairing new devices is easy, and the information is easy to read. The hub was also easy to connect with my Google Assistant. In general I would recommend the YoLink system to anyone setting up a smart home. HOWEVER... My primary focus when buying this base set which included the YoLink Hub, and 2 Temperature / Humidity Sensors was to have my Google Assistant (and IFTTT) read information from these sensors and preform automated actions. Much to my disappointment, these sensors are among the few YoLink devices that are NOT directly compatible with Google Assistant and Amazon Alexa. There is an alarm feature that CAN be linked with IFTTT, but it is extremely limited. Once again, The YoLink system itself is genuinely nice and easy to use / connect with other services. My only complaint is that SOME devices are not compatible with all features. While the sensors I have don’t do exactly what I needed, I am keeping them and the YoLink hub as I will use it for other sensors I plan to purchase in the future.

I read the reviews for this and some of them were unfavorable. What I really wanted this for was just to keep a track of the temperature for my freezer chest and garage fridge. Humidity isn’t really my concern. It is great for the purpose I bought it for. Instructions were super easy, navigation of the app is easy and it alerts me if my freezers go above a certain temperature. I would recommend it.

I was hoping to use at our freezers in our buildings. Its less than a tenth of a mile away and it doesnt pick up.
