YoLink Smart Temp & Humidity Sensor, LoRa Long Range, 2 Year Battery, Indoor Monitoring for Wine Cellar, Bedroom, Nursery, Greenhouse, RV, with App, Email & SMS Alerts, Alexa IFTTT, 2 Pack + Hub

In my experience the YoLink Temperature and Humidity Sensors have been an extremely easy to install and configure and a very reliable product. I purchased my first three sensors at my home in Canada to monitor my deep freeze, my refrigerator and my kitchen air temperature and humidity. I installed them 2025-06-10 and as of today 2025-10-13 they have been in service for 4 mon 3 days. I used Amazon Basics Alkaline batteries and after 4 months all are at 100% charge! The product interface is extremely intuitive and the product provides a plethora of data with the option to download MS Excel or CSV history files for the past three months. The station hub is the "control center and brains" of the service through and to which the sensors communicate to the hub and to the internet. I now added my USA condo to its own hub with three sensors for deep freeze, refrigerator and family room and it is all configured under a second home in the YoLink software. It's EXACTLY the product I wanted and it lacks nothing. It's been designed beautifully and the product itself is flawless and an engineering work of quality. This is an exceptionally intuitive, capable, flexible and reliable product. It should be in your toolkit for home automation for properties outside your driving range. An exceptional product and as a design engineer myself, It's well done, especially for the extremely reasonable price.

Very easy set-up, up and running fast. Works flawlessly and is highly accurate. Easy to move around from place to place. Large display is easy to read. Compatible with Apple Iphone and app is easy to use and add additional products.

Very easy way to monitor and automate my home while away. Modules work well and are easy to set up. Put a temp sensor and smart plug in my utility room to keep it from going below 35 degrees by turning on a heater. Also monitor my freezer temp so no more spoiled beef when someone leaves the door open.

I have tried a variety of Temp sensors for around the house and outside. Some with a console, some internet linked. These sensors are very reliable and have really long range. I can tell if the pellet stove that we use is still running or needs to be reloaded by the temps near it. Very happy with the sensors. I initially purchased the hub and 2 sensors and then added 2 more sensors. great that the system is expandable. Very easy to configure and add more sensors to the app.

These sensors have been completely reliable in the five months I've had them. I've had a freezer door accidently left open by a kid before, which spoiled all of the food inside, wasting hundreds of dollars. With these affordable temp sensors, I have strong peace of mind knowing that I'll be alerted if something like that were to happen again! Battery life seems good so far. One of them appears full and the other close to it, so I believe them on their long battery life claims. They don't use some obscure battery size either, so that's nice. I use mine with the Home Assistant integration, which seems to be well supported. Being able to send customized notifications, toggle lights, or make smart home announcements based on these (and other YoLink) sensors is a major plus to me. Overall, I'm very satisfied. I'm not all-in on the YoLink system yet because I prefer to use Z-Wave/Zigbee for most things, but these seem to be a reliable alternative that is quite a bit cheaper, easier to pair, and has better battery life, while still not using WiFi for communication. The whole package is definitely enough to get me interested in investing more in their system.

These temperature monitoring devices were easy to set up and install. The only complaint is that they keep falling off the wall when held in place with Velcro strips. Probably will need to screw into wall. Nonetheless, they fully satisfied my insurance company requirements.

This is my latest YoLink device and it does what it’s supposed to, as advertised! It’s inside a freezer on my back porch and the hub is in an outbuilding but it’s still connected and working great. Their products are easy to get connected and they stay connected. I haven’t had any of them fall off my home wifi. Their app is simple and easy to use and their products are cost effective.

Got 2 sensors and the base for my cabin in northern Wisconsin to keep an eye on temps during the winter. Was easy to setup and worked great. Alerted me to cold temps within the cabin when if got down to -30 outside. App is easy to use and haven't had to replace the batteries yet on the sensors and it's been about 6 months. Also like that the sensors have a display so you can see the temp and humidity.
