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

These work great! Even inside my fridge and freezer! The display is big enough to se, and they work in the cold temps! Great to know when one of the kids leaves the basement fridge open!!!

I got 2 of these and 1, as you can see, has a bad display. Its not worth the effort to send it back so I hope they improve their quality control/packaging. Not the only yolink issue Ive had either. UPDATE: I made contact with YoLink and they made it right. They sent me a replacement, at no cost, without having to return the bad one. While they may be experiencing some growing pains they do stand behind their products which I appreciate. I do wish the history could be deleted and that reporting times could be adjusted but overall its a good sensor and company.

When used with YoLink smart hub this temperature and humidity sensor sends you alerts when your set limits are exceeded. Very easy to set up with YoLink ap and shows all device data on the ap. I place one sensor in my freezer and one in the house to monitor temperature at a glance from anywhere. Excellent system for peace of mind!

I had a plug in a remote corner of my home that had a competators WiFi controlled plug. I would lose connectivity. I cant blame the wifi plug, but had very little options to improve the sub-prime location of my wireless router other than costly investment in MESH or other solutions. So, I repurposed that plug to another location and used this product from YoLink. Once I set up the LoRa hub (REQUIRED!) and the plug, it works wonderfully. It was easy and quick to set up and when I went to Alexa I was smiling what I found that the YoLink SKILL actually had a positive rating unlike many others. After this great experience, Ive added 4 of their water sensors, an indoor and outdoor thermometer, and got 2 of the FlexFobs. All accessories were similarly easy to set up to connect to the same HUB and very quick to set up and get into my Alexa routines. Literally 20 seconds to set up using the scan QR code in the App. It took longer to open the boxes! What I have set up (so far) • YoLink Hub • 4x Water Leak Detector • 2x Flex Fob (one wall mounted, one to carry) • Indoor Thermometer/Humidity • Outdoor Thermometer/Humidity Pros: • Easy to set up • Good range (at least better than WiFi) • Integration with Alexa • Extra credit for making use of minimal packaging. • The FlexFob can be used in any Alexa routine not just other YoLink devices (under Smart Home each of the 4 buttons is treated like a motion detector) • The FlexFob even included a wall mounting bracket, which was a pleasant surprise for me! Cons: • Basically none. • If I had to complain about something, I guess the mobile app could use some refinement (You need a few clicks to go into settings to change something as a favorite, etc. which maybe could have alternate way, such as a click and hold)

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.

First used to monitor our garage fridge, but stupidly didnt setup the alarm strategy. The fridge failed and we lost tons of food. After the repair, bought 2 more for the house fridge and set them up properly. The house fridge revealed a performance problem that Im working to fix. Its fancy digital settings & display mislead you to expect its controlling properly, but the Yolink temperature graph seems to show otherwise.

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!

I have several of these for cigar humidor. I have calibrated time and again. Every time I get two to match temp and humidity I then put both in humidor and they are then way off from each others by several points. Huge fluctuations and dies not stay calibrated stable-wise. What is the +- accuracy??? Is it low like +- 4% or????

My kids keep leaving the fridge open. Not everyday, but every few months. I am very happy with YoLink’s flood/water and temperature sensors, which have been super reliable and also trigger Alexa routines I can set up. I ordered these last morning. They arrived in the evening. I literally had to open the box and scan the barcode at the back with the YoLink app and I was all set. I stuck one in my basement freezer and one in the basement fridge. It took several hours for the temperature reading to equalize to the actual temperature - there’s a bit of inertia to the temperature detection. Once it stabilized, it matched the reading on my infrared thermometer and my digital probe that I use for grilling. Likes: Easy to set up, very good range. Stores historical readings in the device which are viewable on the app. Useful to see the peaks and dips in fridge temps or house temps. The YoLInk app lets you trigger alerts (from the app) when the temperature deviates from a specified range. It also sends you emails (lets say you are traveling - you could have a friend or neighbor get an email!) Dislikes: Alexa will not let you trigger a routine based on temperature alone. I had my flood sensors set up to announce to my Echos that I had a flood in a specific area of the house.

Heard a lot of negatives about the refrigerator I just bought freezing food in the fridge compartment when they set the dial to Recommended. I had the same problem and decided to get the temperature sensors from Yolink (I already own a number of their products). After installing it, the manufactures recommended settings was way off. I turned the fridge settings much lower and the freezer higher and after playing with the temperature controls, I got the temperatures to be perfect. Fridge stays between 34 and 38 degrees and the freezer between 0 and 5 degrees according the sensors and app. I even got a text one day when the temperature in the fridge went to 33 degrees since my app was set to notify when it gets below 34. I highly recommend these sensors
