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

We travel during the winter and want to insure our home is above freezing. So far the sensors and program are working well

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.

This could not have been any easier to set up. Took ten minutes from opening box to sensor in freezer sending readings. Signal from freezer sensor in garage to hub in living room is full strength. Highly recommend

I read the reviews for this and some of them were unfavorable. What I really wanted this for was just to keep a track of the temperature for my freezer chest and garage fridge. Humidity isn’t really my concern. It is great for the purpose I bought it for. Instructions were super easy, navigation of the app is easy and it alerts me if my freezers go above a certain temperature. I would recommend it.

Works good. Easy install

Moving into a new house and want it setup the way you want and with affordable and reliable products. This is the best way to go as far as I know. Many optional monitors and devices available and does not require allot of hubs. Very easy to add devices as you progress

I dont write a lot of reviews, but this one deserves my time to do so. We have a freezer in our garage, and for whatever reason, the door has been left slightly ajar a few times. And there we are with probably $75 of food that probably should be thrown out. So I went looking for a solution to let me know when thats happened. The YoLink is working great, and has already notified me twice that the freezer door was ajar (temperature rising). Our network router sits in a closet in the middle of the house, and the YoLink hub is plugged directly into that with the supplied ethernet cable. Then the YoLink sensor is in the freezer. It has no problem connecting with the hub through 4 walls and the freezer door. My only outstanding question is whether the sensor batteries will last very long. But still this product is well worth the money spent.

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 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.

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.
