YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range (-22 to 158 Degree) for Freezer, Fridge, Green House, Pet Cage, Smartphone Alerts - Hub Required

I ordered the hub with 2 temperature sensors and ordered a third temperature monitor as we have 3 freezers wed like to manage. It took me a little bit to figure out how to set the settings to trigger an alert to my phone when the freezers hit a warmer temp but once I figured it out it was smooth sailing! We have 3 deep freezers and would be a bit devastated to not know a freezer failed before it was too late Our freezers are in a detached garage but we do have an ethernet cable in their so have the hub plugged in out there. So far these have been working great!!

I bought a temperature sensor/alarm just to see if this thing works. Now I have about a dozen devices and they are so easy to install and configure. Ive called support a few times and the support was quick to respond. I have a temperature sensor in a metal building 400 away and it works perfectly. Easy to recommend this product.

Very happy with this Yolink hub and freezer monitor. Easy to setup.

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.

My wife was complaining that the temperature measurement reported by alexa was off. So I moved the sensor to the thermostat to see the difference and the temperature did not change. So I checked yolink app only to see that all devices were reported offline. Two door sensor, three temperature sensors, two garage door sensors, a water spill sensor, and the hub. Well, must be the hub, I thought, so I rebooted it. The hub and one temperature sensor came back. All the rest are still not reporting... UPDATE: So all the devices slowly updated themselves with yolink hub. My fault was that I did not check in the app to be alarmed when yolink hub goes offline. Now it is ON. A bit disturbing that the hub can go bizzerk while I am away and I can do nothing because it requires hard reboot. Otherwise all these units work good and I am glad I bought them. I wish they had more features.

I bought this to place in the storage compartment of my trailer which I live in during the freeze in Texas (Dec 2022) so I would know I needed to turn on the heater to prevent my pipes from freezing. Worked perfectly. I would recommend this to everyone who needs to monitor any temperature. Easy to set up and easy to use. Yo link has the sensors needed for various items as well all controlled in one app.

Temperature device works great. However, I have my existing THERMOSTAT set to reduce the temperature to 71 degrees Fahrenheit ONLY during sleeping time at night. So I would need to have EITHER 2 different TIMES OF THE DAY and TWO different Temperature settings; One for the day time when I dont need that room at 71 degrees Fahrenheit and one for sleeping time at night when I DO keep the bedroom at 71 deg.fah. Currently I have the Alarm setting giving me a warning every hour of the day...annoying unless I manually turn the Alarm OFF during the day an back on again during the night. But that kind of defeats the purpose of automation.

I have 2 sensors that track temperature and humidity. One is in our garage (tropical climate) and the other is in our refrigerator. I rely on the sensors when I am off premises. They are accurate and reliable. They have a strong connection to the WiFi despite one sensor being quite far from the hub (100+ feet). I have owned one over a year and the battery is holding up fine. Highly recommended product.

I purchased three of the YoLink Humidistats to run 4 brand new humidifiers. I bought them to start this frigid, dry air, winter. Thats One YoLink Humidistat on Two Humidifiers in the Great Room (Living Rm, Dining Rm.) and they run better than I could have ever expected using the YoLink Humidity Meters. Im also running One YoLink Humidistat in the Kitchen and Master Bedroom, each Running one humidifier in each room. This takes total care of the first floor of my home. Its so comfortable now, I cant say enough. They start when humidity gets below 45% and shut off when humidity gets above 50%, restart at 45% and again stop at 50%, thats 24x7. Start and Stop humidity levels are up to you. So Good I bought and am waiting enough to do second floor. YoLink has been so easy to set up. All their devices are about two steps to get you on the YoLink app. Once you see them on the app, you may need a few tips with support because they do so much. Give them a call like I did on my first humidistat and Ive set up the rest by myself.

YoLink Smart Wireless Temperature & Humidity Sensor is really easy to setup. All I have to do is to launch the up, press on set, and scan the QR code.
