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 have purchased around 15 of these now to monitor various temperatures and I love them. Very accurate, easy to use, and connect with no issue. Yolink has many great products and is a great way to give you piece of mind with home monitoring.

The device seems to work well in its app and is pretty accurate compared to other thermometers. I am having problems with Alexa integration and plan to call tech support later today. It shows up on the Alexa app and Alexa can tell me the temp if I ask. The problem Im having is that its not showing up under Smart home in the Alexa app so I cant setup a routine.

Had an issue with my outdoor fridge and wanted to monitor it. I can see the drastic swings in the freezer temp and humidity due to rising temps here in south Texas. Show just how hard your compressor is working in a hot garage. Also will save you a ton of money in ruined food.

These are a little complicated (for a simple mind like mine) to set up and get connected but overall, I like them and have ordered a couple more sensors since.

Bought this to monitor the because it had a better range than other options. I needed to monitor the temperature/humidity in a coldfrrame in my garden. It’s down the hill from my house so I wasn’t sure if it would have the range I needed. Just pugged it in and set it in the cold frame. It works great! I think I will buy another for my small greenhouse in the same location!

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.

I am using this product to monitor the temperature in my chicken coop. I really only care about cold temperature to prevent frozen pollo. I was able to set up a cold temperature alert that goes to my phone. There is no history though, in that if you lose WiFi to the device it registers no temperature until your WiFi is back. I thought it would record the temperature at the sensor and update the app when it came back online. It is great for the price. It only updates in hour intervals so if you want to monitor something more often I would suggest another product or possibly another app could poll the sensor more frequently.

I put one of these in each of my freezers. Even the one out in the garage gets a good signal! It is peace of mind to know I will be notified if there is an issue with the temperature before it is too late.

The thermometer itself alone doesnt connect to phone but besides that it works great

I have over 20 YoLink devices and have been using them for years. They extremely reliable and very reasonably priced. The set up is very easy and their customer service is available and outstanding. Bottom Line: GREAT PRODUCTS AND GREAT CUSTOMER SERVICE
