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

Im usually skeptical with low cost devices, but I was in a situation to see if I needed to buy a new fridge, but wanted to know what was going on with it since it was starting to give me issues. So I purchased the temp/humidity sensor. Let me tell you, this system is awesome! The set-up was amazingly easy, and it was true to its word that it has a long distance connection. I have the fridge on opposite ends of my 2k sq ft home. It goes through walls and sends a signal to the (dedicated, sold separately wifi base) and provides me with notifications on my cell phone as I pre-set the qualifying conditions in which to notify me. Ive been talking to my friends about this unit. Highly recommend it.

I already had a Yolink hub, and I added a couple of these to my system to monitor the temperature of my two freezers in the garage. I was skeptical about the signal getting out of a metal box, but it worked fine. In addition to preventing spoilage in the event of a power failure--I had a multi-tap power strip fail not long ago and almost lost a freezer full of food--the temperature monitors revealed that one of my freezers cycles between -2 deg. and -14 deg. I should probably replace that freezer soon since that wide a temperature swing suggests that the thermostat is not working well. I recommend this monitor. I have had good luck with all the Yolink products I have purchased.

Check your home temperature and humidity from your phone at any time. Works great in an apartment without a smart thermostat and I want to check the temperature when Im away. So simple to connect to the yolink hub.

Wow that was Easy press that button on the back to turn on sensor and setup in app. Of course setup the Hub first. Create and account after connecting Hub.. I connected my hub directly with network cable. Hub does support wifi connection to your network. Once Hub is powered up in app just click the Add icon upper right, enable app to use camera and scan QR. Next click the Add icon again to add your sensor scan QR on sensor and well did I say it was easy. Next go to your Alexa app and go to Skills and add Yolink and Enable and link your account. No need to scan for new devices in Alexa. Just say Alexa what is the temperature on the Themperarure and Humidity sensor you can change the name of the device but ha that was so easy. Did I say it was easy...

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.

Worked easily out of the box (I already owned the hub). Like many, I am using in a cold environment, my refrigerator. So the notification from the device occurs when the temperature goes DOWN. But in these applications, I am obviously concerned if the temperature goes UP, indicating a malfunction or power outage in my frig. UPDATE: I subsequently figured out that one can custom specify a normal range of temps, and be notified when the temp falls outside the range. Now 5 stars.

The Yolink temperature sensor is essential in promptly detecting temperature excursions in any location. We use one on the refrigerator, and one in the freezer. While these sensors do not integrate with Alexa, the Yolnik app can be programmed to send email and text messages when temperature limits are exceeded.

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

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.

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.
