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 travel during the winter and want to insure our home is above freezing. So far the sensors and program are working well

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.

First 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!

After losing an entire freezer of meat, I wish I bought it before. I can see Temps any time and get an alert if it gets warm.

I must be honest and say I was a bit skeptical about this product at first (placing a wifi device inside a sealed metal box), but let me tell you, it really works! Once you get the thresholds set it will send you a notification directly to your phone (via email) when the temperature or humidity has exceeded your setting. Be mindful of your defrost cycle. It will send false readings if you have your threshold set to low. Once I got that figured out, it has worked flawlessly. You can monitor it in real-time via a graph in the app. Super impressed with this little device. It definitely gives peace of mind that my freezer packed with venison will be safe and sound on my next hunting trip.

Out of the box this had batteries installed on the remote sensors which was nice. I plugged in the hub via ethernet into the home router. I have one unit in a fridge and there are no signal issues reaching the sensor as well as the freezer in the garage. Range appears good....signal strength in fridge which is upstairs is still -77dBm). The signal strength for the other sensor directly upstairs from router is -52 dBm). No issues or concerns having these dispursed either in something or further away from the house router. Functionality is also easy to set up alerts or see charts with the data. knocked one star off for lack of ability to enable a push for an updated temp from the sensor. The booklet has the requirements for for a refresh based on one of 6 conditions...otherwise its 1 time per hour. I would prefer a SW update that enables a manual refresh.

humidity 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,

Great product that actually works for freezer in garage. Impressed with product and YoLink

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.

You cant go wrong with these sensors. They are easy to program and have a long range. Tech support is great too.
