Smart Wireless Temperature / Humidity Sensor Wide Range (-22 to 158 degrees) for Freezer Fridge Monitoring Pet Cage/Tank Monitoring Smartphone Alerts, Works with Alexa IFTTT, 2 Pack - Hub Included

I ordered the hub with 2 temperature sensors and ordered a third temperature monitor as we have 3 freezers wed like to manage. It took me a little bit to figure out how to set the settings to trigger an alert to my phone when the freezers hit a warmer temp but once I figured it out it was smooth sailing! We have 3 deep freezers and would be a bit devastated to not know a freezer failed before it was too late Our freezers are in a detached garage but we do have an ethernet cable in their so have the hub plugged in out there. So far these have been working great!!

I have one in a detached shed and one in the attached garage. They work great and were easy to set up.

I had recently placed a negative review of this product. However, after more attempts, we DID get it to work (via cable) and so far it is working well. I really WOULD recommend, though, that your modem has a free plug-in place. That was our problem before; getting it connected Wi-Fi can be a challenge. For now, I have freed up a place on my modem to plug in the hub, and getting the device set up and working took a little bit, but now it seems to be working fine.

Very solid construction and feels heavy/durable. I have only had for a month but battery life is expected to be very long. I use this to monitor my fridge and freezer temp because I was having issues. The temp monitoring isn’t real-time, but I believe it updates every 5 mins. Easy to connect to your router with supplied ethernet wire. I believe there is a wireless option but I havent tried it yet. I bought the one with the provided hub. You can monitor your temps and humidity from anywhere in the world using the app. Very happy with the product. Will buy again for future applications.

Was skeptical about battery operated sensors in the freezer but they work great. Tricky to set up

First, setup was very easy. After calibrating all of the sensors (I have 7 total) I put one in each room and one outside. I can now check the temperature in each room from anywhere. Theres only two issues Ive had so far. 1) after setting up the hub, it downloaded a couple hundred GB of data from the internet. I checked the firmware for all of the sensors and the hub but they were all up to date. Id like to know what all that data was for. 2) it works with Alexa... as long as you only want to know the temperature. It doesnt show the humidity and you cant use it as a trigger to turn on the dehumidifier when the basement humidity gets to 45% or to turn on the fan when the room gets to 74°F, for example.

I had to have my Nephews kids set up for me, as its too much hassle for. I got one sensor in basement freezer, and one in upstairs freezer, and they both get out. My problem is all the false alarms. I set mine to 20°, and my analog gagaes dont show that temp. Another more important thing is if its hooked up to wi-fi how much snooping is going on?

My fridge/freezer starting showing signs of failure so I bought this Yolink device to monitor them and get notified of issues. IT JUST WORKS! Simple to configure, works reliably, and does exactly what it’s designed to do. I especially like the flexibility in alarm settings and also alert settings. I would absolutely recommend this product to anyone. It’s worth every penny!

I have had 3 sensors for apx 30 days that I use in a fridge, a freezer and a basement where temps need to be monitored. They have been very accurate and compare with the analog sensors I left in place until I felt secure with these units. It saves me time and anxiety not having to worry that I’m losing a freezer full of food or very expensive meds in the fridge or pipes freezing in the basement.

I have tried them all. This actually works. The temperature displayed on most freezer or fridges is not the actual temperature inside. This will fix that problem. And if someone leaves the freezer door open in a hot garage….this will let you know before it all goes bad. Truly a great investment. I needed you years ago!
