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

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.

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.

Works well. Excellent customer service too.

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.

Using to monitor temperatures in Kitchen and Garage freezers. Also purchased YoLink Water Sensor 2 and that is working as expected. The hub and sensors have a nice look and feel. Tested high and low temperature alerts and can say they are working well so far. The YoLink app on the iPhone looks clean and works well for me. Dropped a star because setting up the hub to my WiFi network was a challenge. The hub only supports 2.4Ghz WiFi and apparently the iPhone must also be on 2.4GHz WiFi in order to set up the hub to work on a secure home WiFi network. The iPhone kept connecting to 5GHz by default and could not complete the hub setup step. Since 5GHz signals have a shorter range than 2.4GHz, I solved it by taking hub and phone to far end of house where I had a weak WiFi signal. Was then able to setup the hub to our WiFi.

Los estoy utilizando en mi heladería y tengo que decir que funcionan muy bien. Los sensores de movimiento, los 3 termómetros, los sensores de puertas el hub y el altavoz. Todo está trabajando muy bien. La aplicación es un poco complicada de configurar si necesitas que funcione específicamente en ciertos horarios y que tengan un alarma específico. Pero se puede lograr. El hub lo tengo conectado con cable ethernet y los varios sensores están en un local de 110 metros cuadrados con varias paredes. Recomendados.

I 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.

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.

After 6 weeks of use in our RV basement we are very pleased with the performance. We want to monitor the temp and humidity down there due to being in freezing temps. Love the phone app with the ability to set alarms.

Moving 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
