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.

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.

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.

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.

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.

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.

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.

I needed multiple temp/humidity sensors for indoor rooms, outdoors, and for 3 freezers. After much deliberation, I went with YoLink hub + 3 freezer sensors + 5 indoor sensors (the outdoor one is in a protected area). They have only arrived today, but it was all extremely easy to set up, and connect to the app. I used the included Ethernet cable, be warned the power adapter is American, but does have USB-A so can be slotted into Aussie power point. Both cords are short, and I’ll need to get longer Ethernet. It was a little time consuming to go in to each separate device (in the app) to set alarm limits, etc, but now it’s all set up and running beautifully. It says to give an hour for the sensors to stabilise, but it is taking longer for the freezer ones. However, they are performing wonderfully and I’ve been watching the temps drop. They have been sending me alerts about the temp being too high, which is reassuring that they will function correctly once stabilised. Unfortunately, the hub has no battery backup. In a power failure, the sensors will be unable to tell me what temp my freezers are at. So I will have to also get a battery backup for that, but if I was not monitoring freezers this would not be an issue as the room sensors all have displays. Bonus: I have shared the whole set-up to my spouse, and they have joined my “home” and will not need to do set up of the sensors! This is great as they are not “techie.” I recommend this, it’s exactly what I was looking for.

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

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.
