> 24 hourThis 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.

> 24 hourUsing LoRa (long range wifi) this works very well. I have one sensor in my fridge and the signal easily gets through the fridge walls and to the hub 3 rooms away. The alerts are sent to email and/or phone by way of the hub. Set up was easy. The app assigns a widget to each sensor but oddly doesnt label each widget with the name that you assign to each sensor in the set up routine. But thats minor and you can see which sensor name is assigned by choosing a label in the app. Very cool. Now I can see when the fridge door is kept open too long by the wife, ha ha!

> 24 hourhumidity readings are off, i can put the same unit side by side and 1 is 83.5 humidity the other 79.3. always 3-4 degrees off each other, temp off but by 0-1.5 degrees... i think humidity reading are higher than normal, since my other units read humidity 5-8 degrees lower constantly BUT i dont know which is the accurate reading! I dont get the email alerts when reading are above threshold which is cool, but still returning,

> 24 hourOur 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!

> 24 hourMoving into a new house and want it setup the way you want and with affordable and reliable products. This is the best way to go as far as I know. Many optional monitors and devices available and does not require allot of hubs. Very easy to add devices as you progress

> 24 hourI got these for a deep freeze out in my detached garage. This setup quickly and without fuss. Its very accurate and has an impressive range. It was easy to setup custom parameters to alert me to extreme temperature changes sent directly to my phone.

> 24 hourFollowing a service call from on my 9 month old LG refrigerator to correct a sensor problem causing the food in the freezer to thaw I decided I needed a WIFI sensor. I wanted a device that would monitor the temperature and notify me when the temperature rose above my setting in the freezer and refrigerator. After reading the reviews on the various products available on Amazon, I decided to give the YouLink Wireless Temperature / Humidity Sensor a try. After installing the YoLink Android APP and creating a YoLink account, I was able to add the HUB, and the two sensors by scanning the QR Code on the back of each device. I plugged in and connected the hub via the provided Ethernet cable (WIFI connectivity is also available). The hub status changed to online in the APP. I pressed the SET button on each sensor and its APP screen status changed to online. Each sensor immediately began displaying the temperature and humidity matching the information display on the sensors. I placed each sensor in the refrigerator and freezer sections verifying their accuracy with a separate temperature sensor. The Alert setting for high/low temperature and humidity were easy to setup with the APP. I find that the Alert notifications are almost immediate. The documentation provided with the hub and sensors is very basic, easy to following and gets the setup done quickly. I received links from YoLink on the additional more advanced setup options via email. I called the tech support number with some questions on Saturday and was able to speak to a knowledgeable tech support person. So far, I am impressed with the YoLink Wireless Temperature / Humidity Sensor and highly recommend it.

> 24 hourBe 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.
