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

This product a bit confusing to install. But the extra time it took my husband to install is worth confidence in our 2 freezers accurate operation. We freeze fresh garden veggies and our summer salmon catch and a new beef. A product we are very happy to have and satisfied with absolutely.

We buy meat in bulk from a friend that has a connection to the farm. We store the bulk meat in a freezer in the garage. My problem was my children were opening the freezer to get something, a popsicle or something and occasionally the freezer door was loosely shut. This allowed the heat from the garage to come in and defrost the meat. On one occasion the meats blood was leaking out of some of the meat packages, ice cream was destroyed etc. So I purchased to put inside the freezer. You have to buy that hub, but is the easiest thing to install. I downloaded the app, created a login, took a picture of the bar code on hub by the app, hooked the hub up to the router, its done. Set up the thermometer by taking a picture of bar code in the app, its done.

It works fine from the base station all the way inside a freezer on the other end of the house.

The YoLink app is simple, easy to use, and very straight forward. Pairing new devices is easy, and the information is easy to read. The hub was also easy to connect with my Google Assistant. In general I would recommend the YoLink system to anyone setting up a smart home. HOWEVER... My primary focus when buying this base set which included the YoLink Hub, and 2 Temperature / Humidity Sensors was to have my Google Assistant (and IFTTT) read information from these sensors and preform automated actions. Much to my disappointment, these sensors are among the few YoLink devices that are NOT directly compatible with Google Assistant and Amazon Alexa. There is an alarm feature that CAN be linked with IFTTT, but it is extremely limited. Once again, The YoLink system itself is genuinely nice and easy to use / connect with other services. My only complaint is that SOME devices are not compatible with all features. While the sensors I have don’t do exactly what I needed, I am keeping them and the YoLink hub as I will use it for other sensors I plan to purchase in the future.

Update; changed my rating to 4 stars for two reasons : First, and most importantly, was the level of customer service received after posting the original review. This company stands behind their products and is willing to make it right if something is wrong. Second, I was able to get the hub to stay online by whitelisting the wifi. Still cant get the ethernet to stay online which only 4 stars, but this might be due to my hardware firewall, still working on it. Overall, good products, GREAT company, I can now recommend them. Worthless ecosystem, Id give zero stars if possible. Hub will not stay online, either wifi or ethernet. When the hub drops, all the sensors start going offline and I start getting water leak alerts, power failure alerts, etc. Save your money and buy something else.

I have 4 of these devices in my house. I’ve had a few issues setting these up. Customer Service has been exceptional in guiding me through the process of completing the setup. I highly recommend this product and company.

The product is easy to install. Long range and communicates well with app and hub even though the sensor is in the garage in a freezer. Awesome

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 bought this because we have a stand alone freezer in our basement. We had an instance where the door was somehow not closed all the way and we lost a lot of food. I had been searching for a device to alarm us if the temperature dropped in the future. Im an old guy and did have a couple of snags in initial setup, totally my inability toread directions. I attribute that to being a man! Thankfully the support I received from YoLink was the best support I have ever received for anything I have ever bought. Thanks to the guys at YoLink, I have an up and running unit connected to Alexa as well! Thank you!

Love having these in the freezer for piece of mind. We have had freezers go bad before and lose everything. Decided to purchase these before we bought half a side of beef. Easy to hook up and install to router. App works great, easy to set temperature ranges. I get notifications if it goes above or below set temperatures. So glad they make these now.
