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

Works great. I can now monitor the temperature in my house wherever I am as long as I have internet.

This sensor is affordable, easy to set up an has a incredibly long range including excellent wall and freezer door penetration. Customer service is quick and helpful. I have only one issue, which they have said they will fix in an upcoming release, which is that the alarm can not be used in a freezer scenario. As you see in the photo, all freezers are below temp threshold, so they would alarm continuously. They are reducing the lower limit to address this soon. In the future I hope they offer an even lower cost version without the LCD display which is very nice but useless when inside a freezer or other place I can’t see... I look forward to testing their other sensors soon.

This worked great for 9 months. Stopped working. Contacted customer service (I use that term loosely) they gave me the run-around. Did nothing to solve my problem gthey finally sent, and this is true, a message that said, Have a great day. If you get a usnit that wokrs, youre good, but if you dont, sorry.

I have had several temperature sensors and leak sensors set up in each of three different homes. I have monitored up to 32 sensors at one time. I have leak sensors at all of my plumbing fixtures. I placed temperature sensors in a couple of locations in the house, in my fridge, and in my freezer. This is the best system I have found. It’s easy to update when moving to a new home. I can check status at a glance and can sit notifications on temperature and humidity parameters. I change the batteries about once a year.

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!

I confused two products that I bought. Check my Govee review for this YoLink item. I blame Amazon for not having the product brand name on the items to review page … and the icon photos are extremely small! Amazon gets a 2 star on that “service”

Pros: Easy to install, communicates with rest of Yolink integrated system, can provide voice warnings when used with a speaker hub. I purchased two thermometers that I wanted to integrate with the rest of my Yolink water leak detection and shutoff system along with my speaker hub. Installation was a breeze, scan the qr code, push the set button, and you are in. Because I have a Yolink speaker hub I was able to program the thermometers to issue a voice warning when the refrigerator temperature went above 42 deg. F (the high and low temperature limits are programmable). Programming is very easy and intuitive. Without a speaker hub, users will receive an email and notification and, optionally, a text message. Customer service is excellent. Batteries are supposed to last two years or more and the Yolink app shows the battery status of all components. When compared to a calibrated digital thermometer, the Yolink thermometers were well within one degree of accuracy. As a bonus, the thermometer keep a history of temperature and humidity. These thermometers are designed for indoor use. Very pleased with this product.

I have 6 of them, I tried several others before and did not worked as this ones. I use them to monitor my cold rooms and freezers and they worked as advertise. The cold rooms and freezers previously could not being measured due to “distance” or thick walls, the signal with yolink has no problem. I write this review because this just paid itself, one of the rooms send an alert for high temperature, someone left the door opened, this has just saved me a lot of money and a big headache. I recommend them!
