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 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 like this little home automation device. I works stand alone (you can easily read it). It has a nice app with possible automations and it integrates easily with other systems

I have two of these sensors, purchased mostly to monitor the fridge sensor. The first one had a faulty antenna, it fell out, so the range is quite poor. The other goes through batteries very quickly, its faulty in some way. Other than those two flaws they seem to work quite well.

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.

Easy to set up with yo-link, works as expected. Good range and quality

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

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.

It seems like some of the complaints on these is that theyre not accurate so just to make sure I purchased several analog and digital temperature sensors to check them against their readings. I must say the temperature readings are spot on or at least within 1 degree of spot on which is pretty friggen accurate for such a small sensor. Overall these were probably the easiest things Ive setup in years and literally just scanned QR codes to get it to work; not a single problem the entire way! For something this affordable, adjustable, reliable, and accurate its one of the best investments Ive made in a long time! Hopefully this company does well because I cant wait to see what other sensors they can add to make my life easier! Ultimately you cant go wrong with these, there literally was zero downsides and I cant say enough good things about them!

The YoLink temperature sensor is fantastic. We purchased three YoLink temperature sensors. We put one in the freezer, a second in the freezer of the main fridge, and a third in the freezer of the smaller fridge. The devices are rugged, accurate, compact, and even nice looking. Setup was incredibly easy. The app is great. We get phone notifications and emails (depending on my setup) if the temperature or humidity is above or below the range I set. It is particularly helpful if we leave the freezer door slightly open. We purchased these temperature sensors because of their excellent ratings to protect our foods and refrigeration appliances at home. Once, before we had these devices, we were traveling for a couple of weeks, and the fridge stopped working. Because we did not have these temperature sensors then, we did not know until we got home. The food had rotted and stank horribly. The whole house was smelly for days. We cleaned the fridge and had it repaired, but the smell never went away from the fridge, and we had to dispose of the fridge and buy a new one, which was a big expense. Customer service is excellent. We are very pleased with the YoLink temperature sensors. Since purchasing them, we bought other YoLink devices, including leaks sensors and motion sensors, and we like them all.

I already have a hub and 3 sensors. Adding 2 more was as easy as scanning the QR and pressing the button. I added one to my shop and the other to my greenhouse. Setting the temperature alarms was just as easy! I tried other temperature sensors and they just didnt have the transmission range. Battery life is fantastic! If you need to monitor temperatures, Yolink is the way to go!
