Great cost effective solution to monitoring and automation.
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.

Best Temp Sensors Ever
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.

Great products!
This is my latest YoLink device and it does what itâs supposed to, as advertised! Itâs inside a freezer on my back porch and the hub is in an outbuilding but itâs still connected and working great. Their products are easy to get connected and they stay connected. I havenât had any of them fall off my home wifi. Their app is simple and easy to use and their products are cost effective.

Works great in freezer
4stars so you know im not a bot.Works incredibly well. You can set up what temperature you want it to alert at, and it will send you a text message if your freezer gets too warm.Yes mine lives in my freezer all the time, currently set to 3-5* f. every so often i take one out and let it warm up just to verity it works, and it does flawlessly. You never have to worry about your freezer going bad AND losing everything in it, just your freezer going bad.

Excellent remote temp sensors
These temperature and humidity sensors are amazing. I’ve had one in my deep freezer for a year and never had a problem with it. I can probably go another year before having to change batteries. I even have a sensor in my detached garage so I can get an idea of the temperature outside. Neither sensor has ever disconnected from the hub…not even 1 time in a whole year! Thats unheard of these days with all of the wireless stuff we use throughout our day!The sensors and hub were very simple to setup. After everything was linked. I was able to start setting up the app and my preferences…sensors named…high temp alarms set…etc. The alarms come as emails. You can even see the history of all the data.Honestly, this was the best purchases I made to ensure I don’t end up with a freezer full of rotten meat. Excellent product…well worth the money!!!

Gives me peace of mind
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.

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 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.

Yolink products are the best smart home devices that I own. Reliable, accurate and have long connection range. The batteries last for an extremely long time, unlike claims from other smart home devices and cameras.Easily attaches to Home Assistant my main smart home brain. Also attaches to standards devices such as Alexa and Google.
