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.

My white house is smarty thanks to yolink from temperature of which I have an outdoor and an indoor

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.

I ordered an additional temperature sensor as I have a few already and I am happy with them. I also have some water leak sensors. I was having a little trouble setting it up and contacted customer service and they walked me through it as they always do -I am very happy with the product and the service!

Although YoLink does not support the major home automation protocols like Z-Wave, Zigbee, Matter or Thread, these devices have a major plus, they work, they work the first time and very easy to set up which cannot be said for the above protocols. Adjustment provided if you need to make an adjustment to temperature readings, mine were close enough that I did not bother. History display is excellent and alarms seem to work as intended. Note that it requires its own hub but the hub is inexpensive and only one is needed. I have not tried to get system to work with Google so can not speak to that. Excellent for use in freezers, work well through the steel box.

Well worth the money I paid, the health inspector loves this system. I can monitor my temps, get alerts or turn them off, I can look at history and see the refrigeration cycles and consistency of the units. Ive caught problems before they destroyed product twice now by just paying attention to patterns.

Good quality products that are easy to setup and work properly right out of the box

Love having an App on my phone to check my stand up freezer temperature wherever I am at. Took a bit over 10 minutes to set up. Well worth the sense of security knowing that my food is safe

These temp sensors work great. Phone app work will very east to set up.

I use several YoLink sensors to monitor for leaks and these for monitoring our refrigerators while we are traveling. I can check the condition of things around the house from anywhere on my phone. Gives me piece of mind along with my security cameras.
