> 3 dayI 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!

02-04-2025We 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.

> 3 dayThis 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.

> 3 dayMy immediate need was an alarm for a garage freezer, which is an older freezer and I had become aware that if we have a breakdown issue, could lose several dollars of food products. Simple audio alarms were not an option because of the distance of the de-attached garage from the house. Plus there are days when I do not even go out to the garage to hear an audio alarm. And I was concerned about relying on wi-fi shown on other systems. I was suspect about the quality from my router wi-fi signal to the garage and a sensor inside the freezer and then back to smartphone. The YoSmart and the Lora tech works extremely well, as advertised. I have a sensing unit in my garage freezer and get alerts on my email (text and Alexa are also options ) when the temp goes in/out of the range that I have set. As a new user I needed the YoSmart Hub as well and the package I ordered came with the Hub and two temp/humidity sensors. The second sensor is used in our inhouse frig. Since these worked so well, I have purchased a motion sensor and attached inside mailbox to alert to when postman opens and closes door, to alert me with an email when I have mail. And I purchased a third temp/humidity sensor and I am using it in the attic to monitor temperature and humidity. We have an automatic attic fan that comes on & off with a mechanical setting of temp and humidity. With the YoSmart sensor in the attic, I will be able to see the range of conditions in the attic as the weather changes. And with those changes I will then make setting adjustments on the automatic attic fan. In our area of the world, weather is full extremes in all Seasons and I believe the additional information provided by the sensor will help me make better adjustments on the fan and in turn keep the attic temp & humidity under control. Set up on the Hub and the sensors is a snap and instructions are very clear. Since the Hub is connected to the Internet, sensors can be monitored outside the home, via smartphone. Very pleased with this product - looking for other applications in and around our home.

> 3 dayFirst off I have another system I bought on Amazon that has no communicating Hub between the sensors like Yo-link does! What that means Is much longer range that I needed to reach my outdoor enclosed well pump house my ThermoPro sensor couldn’t stay on line kept loosing signal till I could physically get back to my lake cabin and unplug it to reset it then after I left it would go offline again within a day or so! The Yo-link reaches the pump house with ease! But better yet it also reports to my phone via the app when temperatures dip below or above the temp range I set to be notified about if that happens! Also the sensors use two Tripple AAA batteries it comes with alkaline, but I chose to instal lithium which I know lasts up to 5 years in the frozen tundra where I live in Wisconsin from my experience with other weather stations units I had which used an outdoor sensor but they were not WiFi capable just sensor to station which sets on a table in the house. Yo-link has its own WiFi hub that’s only about 5”X5” square and less than a inch high that connects to your router and is powered by a usb cable and plugs into any power outlet, this hub is the only part that plugs in and powerful long range communicates with as many sensors you want to place in and out side of your home! So you can put them anywhere no need for power for every sensor like the other brand has to have, and the other brand doesn’t have the hub to broadcast to and from the individual sensors that’s why you get the long range, the other brands sensors has to each connect to your WiFi individually and they are finicky as to where they pick up signal! To far away or inside another out building without WiFi and you don’t get connected! So I was really pleased and surprised with Yo-links performance, and it solved all my problems for about half the money of the other brands price!

> 3 dayTook 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!

> 3 dayOne is monitoring vegetable storage in the garage, one is in the chicken coop, both places where we need temperature and humidity monitored. We have the app on two phones, base station is in the middle of the house. Great buy.

> 3 dayI 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.
