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 bought the temp/humidity sensor to replace an older iHome sensor that I didnt have faith in anymore. The Yolink sensor shows similar readings to the iHome sensor, so maybe I didnt need to buy something new, but I had a great experience using Yolinks motion sensor to turn lights on in a bathroom that doesnt have wall switches so I decided to give another one of their devices a shot. Adding the Yolink sensor to the Yolink app is a breeze - you just scan the QR code and youre on your way. It appears to report the temp and humidity every few minutes (I noticed some older reviews mentioning it only updates once per hour) so that is a pleasant surprise. However, I use Alexa for all of my smart home needs, and this sensor only shows temperature in the Alexa app, and half of the display in the app is cut off. Im disappointed that the sensor doesnt send humidity data to Alexa, which means I cant trigger automations inside Alexa for alerts or turning the basement humidifier on and off outside of a set humidity range. There are only 2 data points that the sensor needs to report, and the fact that it only reports one outside of the native app (and the one I didnt really care about) really bums me out. Ill most likely stick this in the deep freezer in my garage and look for another option from another company for automation of the humidifier. I suppose I could get one of Yolinks smart outlets to handle this automation inside Yolinks app, but not being able to have my Alexa speakers produce a notification and not being able to ask Alexa what the basement humidity is leaves me wanting/expecting more.

The base unit and temp/humidity sensor were quick and easy to set-up . The creation of automations is not easy. The difference between an alarm and alert is unknown to me still. This needs to be explained better and the automations need to be much easier to understand and set-up.

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.

These work great! Even inside my fridge and freezer! The display is big enough to se, and they work in the cold temps! Great to know when one of the kids leaves the basement fridge open!!!

I got this to monitor the temperature in a storage shed. I wanted to link it with Alexa and set up a routine to turn on a vent blower at a certain temperature range. Turns out this links with Alexa fine, but only shows the temperature. Thats it. The humidity does not even show in Alexa. You cant even ask Alexa to state the temperature from it, you have to manually look at it. And Alexa will not recognize it to set up a routine like I wanted either for some reason. Well, at least I can monitor the temperature and get a notification from the Yolink app when the temperature gets too high. Keeping it because I might use it elsewhere, but Ill be buying something else to trigger the vent blower.

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

Transmits from my shop building about 120 ft away from house and alerts me if temperature is getting close to freezing.

The Yolink temperature sensor is essential in promptly detecting temperature excursions in any location. We use one on the refrigerator, and one in the freezer. While these sensors do not integrate with Alexa, the Yolnik app can be programmed to send email and text messages when temperature limits are exceeded.

Nice to be able to check it and get alerts in case power goes out so we don’t lose our frozen meat investment.

I have several of these units monitoring high and low temperatures. They work well, even when cold; they alert me when the freezer gets too warm. Alexa integration is lacking, however; you can’t trigger events in Alexa when the limits are exceeded. The in-app alerts work, but aren’t as flexible.
