Fantastic monitoring solution
I really like this set. It is easy to set up, works exactly as advertised and does an excellent of monitoring both my humidor and my wine cabinet. Humidity and temperature readings appear to be very accurate and sensors are very easy to read. I highly recommend this product at a great value/cost ratio.

Reliable, easy, customizable
Easy set up, reliable function. Excellent wireless connectivity between the hub and sensors. App works fine, lets you calibrate device temperature setting. Reasonably easy data history export to csv. Battery life is great so far and totally reliable!!Minor notes: Only two months back of history is saved, and you need to use the app since there is no online interface from a computer browser.Excellent value!

Works great. Long range. Easy setup.
These work great. Have one sensor in the garage and one sensor in the basement and the base unit upstairs. The signal is strong for both sensors. The announcements are loud and clear from the base unit and the email and text messages to my phone are instantaneous with the announcement.The app info works great from anywhere. Great product.

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.

Works fine
I have a half dozen Yolink lead detectors around the house and they work great, so I wanted to stay with the Yolink brand. I like the app and quick notifications. These sensors are fine but not great, so just 4 stars.These replaced stand-alone temp sensors in both of my fridges. Compared to the old sensors, one of them is reading a couple deg too high, and one too low (I’ve also swapped them to confirm). The third one I’m using to monitor a room. Not that the old sensors are calibrated, but they are much closer to the temp setting of the fridge.I do like the history feature you get on the app. I can see at a glance the high/low points and how long the run time of the fridge is, just wish the high/low temp were displayed. Another “would be nice to have” is a mounting option, like mag backing or hook. Interesting fact I noticed is that my 30+ yo fridge can maintain a much tighter range than my 1 yo “Pro” series fridge.

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!!!

YoLink thermostats & Hub work better than expected – highly reliable for monitoring temp & humidity.
At first I didn’t like that LoRa communications, thinking that WIFI would be better. Now I see it is significantly better for the YoLink having it’s own network using LoRa. 1. consumes less electricity (batteries have lasted more than a month with almost 100% charge left); 2. not subjected to any wifi communication loss (never seen any device lost connection and communication link goes further than wifi); 3.Highly reliable in bathrooms and even outdoors (as long as sheltered from direct rain – can see humidity rise after showers, see when a room is too cold risking freezing pipes); 4. Alerting is fantastic – emails and text message when remote laundry room gets too cold. 5. Thermostats can be placed anywhere, left with little concerns.So far, the YoLink hub and thermostat have exceeded my expectations. I have it directly connected to the network using ethernet which is simpler – just plug and play. Adding thermostats to the hub is super easy using the app.

Grundsätzlich funktioniert das Produkt sicher gut aber das Problem ist das es aus Amerika kommt und über den US Server läuft.Zusätzliche Geräte bekommt man nur sehr schwer über die Amerikanische Seite und dort wuchern die Preise wegen des Versandes + Zollgebühren.Ein anderer Anbieter aus England auf Amazon hat nur Sensor ohne Hub verkauft, hab den dann aber nicht mit diesen Hub verbinden können, da der Sensor Plötzlich eine andere Typennummer hatte, und der dann auf dem EU Server laufen sollte.Für EU habe ich aber keinen anderen Anbieter mehr gefunden und schließlich alles wieder zurück geschickt.

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.

The hub is an absolute pig to set up but once you have done then it’s a great piece of kit for ensuring that I’m notified if the freezer out in the garage fails. I’m using the other sensor to keep an eye on the temperature in the freezer in the house.* important to note that it will initially tell you that no internet has been found – just ignore it and carry on with the set up*
