YoLink Smart X3 Version Outdoor Temperature Data Logger with Probe, Thermometer, 1/4 Mile Range, 5+ Years Battery Life, Emails, Text, App Alerts, Alexa, IFTTT. Pool, Hot Tub, Fish Tank. Hub Required!

Getting reliable and accurate pool water temperature seems easy but most thermometers, especially digital ones are not very accurate or not calibrated properly from factory. In an effort to ensure the most accurate readings I’ve used multiple analog (alcohol and even mercury) thermometers with varying degrees of success. Getting all thermometers to agree seems impossible while most of the good ones do come very close to each other. Now using analog ones is great since they never need calibration, however they are not practical as you have to go to them rather than get remote readings, and of course there is no historical data. In my case I wanted accurate remote readings often and nothing floating around in the pool, so I took advantage of a water pit in the pool concrete deck, and installed multiple temperature sensors in the same spot and begun testing and gathering temperature data. Before getting the YoLink LoRa Temperature Sensor YS8014 X3 I had both several Aqara and YoLink YS8004 sensors. I had some connectivity issues with the other brands due to the “underground” location, however all the YoLink sensors connected perfectly and quickly, so I narrowed down my options to YoLink. While all YoLink sensors seemed to work very well, I was curious to see how much better the new YS8014 X3 sensor was and how it compared to the others. While the end results proved that all sensors were very close to each other, I really liked that the new YS8014 X3 allows for more samples more often, as low as 1 minute and as long as 1h. Interestingly 1h is the norm with most such sensors. The YS8014 X3 also has a convenient LCD display that will also automatically turn off at your choice timeout to save batter life. Just like the other YoLink temperature sensors the YS8014 X3 uses easily replaceable batteries but now there is a 2y and 5y battery option at purchase, so more flexibility and longer battery life overall. It also saves temperature data internally in case the hub us off-line then sends it once it re-connects so no data is lost! I will end up keeping the YoLink YS8014 X3 sensor in the pool water pit and move the others to my kitchen refrigerator and garage fridge, to keep an eye on them and get alerts should the cooling stop. I lost a full fridge of items a while ago due to a failure of the garage fridge, and at the time I had no sensor to monitor the inside as all I tried could not communicate from inside the fridge, except YoLink! Anyway, I am very pleased with ALL the YoLInk temperature sensors and would certainly recommend them for almost any need given the flexibility features, great support services and long range LoRa technology.

Best I could find but not perfect. Would be better to have faster app temperature update intervals (5 minutes would be fine instead of 30). Or at least it should update when I'm looking at the app. A backlight on it would be nice too, activated for 10 seconds by a motion sensor. Also would be better if the device itself had a beep of some kind so I know alert temperatures have been reached. I don't want the yolink siren or another echo device for the alarm. The alert phone notifications work (even with phone asleep) but what if my phone is muted or battery dies, or I'm asleep and my phone is in another room? Also on Alexa it only shows Celsius, no option for Farenheit. Overall the device works well enough and as intended, just hoped for more. I don't mind changing the battery every 6 months or so. No need for 5 year battery.

This Yolink smart X3 outdoor temperature sensor is just what I was looking for. I needed a way to see the water temperature of my outdoor wood furnace with out going outside to check on it. The best thing about this device is the long range Wi-Fi that Yolink is known for. I have several Yolink devices that don't disappoint and neither does this remote temperature device. The probe is a nice length and the display is clear and easy to read. The app is super easy to install and navigate. The only CON I would give this device is that you cannot update the temperature on your phone, on demand. Sometimes it updated immediately upon opening the app and other times it could take 10 minutes. It would be nice if you could poll the device to update actual temp on demand.

First of all, these sensors are fantastic and they work without worries of range limitations, mesh routers or repeaters. The manufacturer doesn't publish or include an Alexa Command example...funny and strange right?!?! Well for the temperature sensor...it is as follows... "ALEXA WHAT IS THE TEMPERATURE OF 《Sensor Name 》SENSOR. Don't try and short cut this to something lame like "yolink"....I found that won't work, its seemed to be a non performing reserved name. There is a section under Alert, Allows you to set high and low alarms and it works flawlessly. Allot of people complain, about Alexa integration, It's not enough for me to take even a half a star away. Range, Price, Function and Battery Life...all 5 stars Advice to Company...write some simple tech docs, or publish some you tube videos to make this simple stupid for non techies and I think it would be better recieved and hit a greater marketshare. Incredible Battery life, a huge plus that many items work off rechargeable AA batteries. Love your product line up...Great Stuff!!!

UPDATE ... I found a mounting hole on the back of the device! The hole was obscured by a metal plate with a stick pad on it. The metal plate is magnetic. So instead of there being no reasonable option for mounting, there are actually two! On that basis Im changing my review to 5 stars. Still a very trusted brand with me! :) I have many YoLink devices and I'm a huge fan of the brand. That said, this is the first device I've purchased that I'm disappointed with. The reason? It's an outdoors thermometer that has no means for hanging the device up. Instead of a mounting hole or a little loop of cord, they went with a sticky pad. Those don't work on brick ... in fact those don't work on many outdoors surfaces ... and even if they did, one doesn't always want to mount something in that way. The older model was much better designed in this regard. Hopefully this feedback gets to the YoLink team.
