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

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.

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.

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.

Works great. I’ve been really impressed with the YoLink sensor for monitoring temperature in my crawl space and attic. I needed something reliable since I don’t want to be checking those areas often, and it’s been rock solid. Setup was easy, and it gives me peace of mind knowing I’ll get alerts if anything changes. Highly recommend for hard-to-access spaces.

We’ve been using this sensor set for about two months now, and it has already proven its value. We installed two of the sensors in our stand‑up freezers, mostly for peace of mind. A few weeks in, we got an alert that the temperature was rising in one of the freezers. It turned out the freezer door hadn’t fully closed, something we wouldn’t have noticed until it was too late. Because of the notification, we caught the problem early and saved all of our food. That alone made this purchase worth it. Setup was quick, the app notifications are fast, and the sensors have been consistently accurate.

They have worked well but I have issues with the app. I have several of these in different locations and I cannot tell which one I am looking at when I am looking at the app. It shows the temp of each separately and I have to open each one individually until I find the one I'm looking for. Also, the order they are in on the screen changes so I can't just remember that the first one is for the basement, as an example.

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.

I bought this after a freezer was accidentally unplugged and ended up ruining $100s worth of food. Setup was very easy. Downloaded the app, paired the base, then paired each sensor. It took all of 15 - 20 minutes. The signal seems strong enough for my use, there is about 20ft between my freezers and the base. So far the battery has stayed strong and the connection has been stable between both the sensors and to WIFI. A few days after setting the sensors up, I found that one of my freezers was not consistently getting to the deep freeze temperature range, I was able to adjust the thermostat and the food isn't burning as quickly in that freezer anymore. The device likely paid for itself with that single discovery. A bonus is that I found YoLink has an integration with Home Assistant. It allows me to double down on the alerts and get the freezer temperatures on my dashboards for additional ease of mind.

Great products. Simple set up and all working well. Very handy.

Excellent quality hardware, well packaged upon opening. Hub and sensors both seem solid, not cheaply made and great quality. Setup was very easy, less than 5 minutes. Recommended setup is to hardwire hub by ethernet cable to router or your home hub. Connected within 10 seconds. Lights easy to see for power and internet connection. Using smartphone to scan QR code simple and identified hub immediately. App on phone allowed hub to be assigned to a room. App simple to use and I linked the Yolink app to my Google Home without difficulty. Temperature sensors also worked right away, no issues with identification of product using QR code on devices. Converted from Farenheit to Celcius easily. Temperature readings instantly and calibrated perfectly to temperature measured by another device. Easy to set up warning temperature alerts and both unlimited email and limited SMS texting alerts (20/month) included as part of product purchase.

Produit bien fait. L'application est complète et bien faite. La configuration est simple et le processus efficace. Je suis très impressionné par ce produit que je recommande sans hésitation.

I was very pleased with this purchase. We live in a cold climate and travel a lot. A big fear is to be away and the furnace packs it in. We received these yesterday and I set them up. Really easy installation with no issues. Install a phone app, scan the hub and the sensors and you are ready to go. I looked at various alternatives before purchasing these but the advantage with this one is the options where you can connect the hub directly into your network using a network cable and it can be plugged into a power outlet. With wifi there is always a chance that it drops and I do not need to work about hub batteries failing. To test the unit we moved one of the sensors into our unheated garage and within minutes we received an alert to our phone and via email about the low temperature. Now we do not need to have someone go into our house regularly while we are away.

The system is very easy to setup and the software is relatively user friendly. I removed 1 star for 2 reasons. First, the system claims to be Alexa compatible, and it is - to a degree. Once you enable/connect your Alexa account in the YoLink app, you can ask Alexa the temperature for the device. What you can't do directly, is have Alexa notify you if the temperature sensor alarms! You have to use a combination of 2 other programs to make that work. The other thing that could/should be improved is how the sensor is mounted in a freezer, for example. It would be convenient to have an clothes-pin type clip on the back to enable the sensor to hang from the front portion of the freezer door.
