YoLink Smart Wireless Temperature/Humidity Sensor Wide Range for Freezer Fridge Monitoring Pet Cage/Tank Monitoring, App Alerts, Text/SMS, Email Alerts, Works with Alexa IFTTT, 2 Pack - Hub Included

Yolink sensors are the best. I use them to keep track of everything from inside and outside temps to reptile enclosures and hotspots, even my koi pond temps. Pair them with some yolink plugs to automate everything. Then add some door sensors to know everything is locked up.

We bought this to track temperature when the power is out. We had an 8 hour power outage recently while we were out of town. Even though our WiFi was also out it was storing temperatures. I was able to see the history once power was restored and knew we hadn't lost anything in the freezer and probably just some of the dairy in the fridge. It was very helpful determining what needed to be thrown away. It also gave me peace of mind to be able to see the data on the app when it would be several more days before we were home.

fairly easy to set up. it appears to be accurate, and easy to monitor on my Android. The one issue is the hub is not super friendly to hook up wirelessly. I ended up plugging it directly into my router.

Product is very easy to set up and easy to use. Our Honeywell smart thermostat started giving very high humidity readings. I got this product to use along the smart thermostat to test it. It appears the smart thermostat is starting fail. I like that fact this product can be acceased via a mobile app via the internet. Other products only worked via bluetooth and a mobile app.

The device accurately reports the temperature from inside the freezer of my garage refrigerator to my phone in the house. I don't know yet if it will report when away from my home. However it can send text, email, and app notifications to any location based on set alert parameters. The installation is not difficult, but requires some time to set everything up.

i bought this because my freezer was left open and everything was sopiled afterfilling it I thought I should monitor the temp. once it was set up, I found that the freezer was set way too cold. now I can make sure it is at the correct temperarure. it will send me notifications it the temp gets above degrees.

Set up was quick and easy. Had zero issues connecting to wifi. I was notified when the sensor went offline, so I was able to move the hub closer, and it has not happened again. I can now breathe easier knowing that I'll be notified if my outdoor freezer trips the circuit again. No more losing hundreds of dollars of frozen foods!

I bought this because my freezer has started freezing up every so often. Unfortunately, by the time I notice there's a problem, some of the food has already begun to thaw. I wanted something that would alert me before that happened again. When the package arrived, it came in a small, plain cardboard box. Inside were the hub, two sensors, and the USB power adapter. However, the USB cable and Ethernet cable needed for power and internet connection were missing. I contacted customer service, and I was pleasantly surprised. There was no wait time on the phone, and the representative was very helpful. I explained that the cables were missing, and she took my information and said the shipping department would either email or text me with an update. The whole process was quick and hassle-free. After dealing with other companies' customer service in the past, I was expecting it to be a frustrating experience, but it wasn't at all. The very next day I received a text letting me know the missing items had been shipped. A couple of days later, the package arrived with everything I needed. I downloaded the app, and the setup was simple. Within a short time I was monitoring the temperatures in both my freezer and refrigerator. I was able to set custom temperature and humidity alert ranges to match my preferences. There are a lot of additional settings and features that I haven't explored yet, but so far it has done exactly what I wanted it to do. I would definitely recommend this product if you want some peace of mind and protection against losing hundreds of dollars' worth of food due to a freezer or refrigerator failure. I also like that you can expand the system with additional sensors, such as water leak detectors, security sensors, and other smart home devices.

Works well. Setup could have been better explained. Good for monitoring temperature when you're away provvided you have wifi.

Overall great product and easy to set up. However one of the temperature sensors arrived with the app telling me the battery is already at half used so that is frustrating. Hopefully it still lasts a year or so without needing to be replaced.
