Review: Great Alerts for Pool, Spa, and Equipment Monitoring - I use these in a couple of different ways and they have been extremely useful. For my pool and hot tub, I mount the sensor under the skimmer cover and let the probe dangle into the water. That lets me see the water temperature at a glance, and I can set alerts so when I am heating the hot tub, I get notified when it reaches the temperature I want. The sensors are not fully immersed, but they have held up well to outdoor exposure. I did have one instance where water got inside a sensor, but after cleaning it out, it started working again without issue. I also use one in my pool filter shed with the probe attached directly to the filter motor. After having a pump fail to prime once and overheat, this has been a great safeguard. I now get an alert if the motor temperature goes too high, giving me time to shut it down before damage occurs. For monitoring temperature and getting timely alerts, these have been very effective and reliable for my use cases.
Review: Only if you care about range, reliability, long life and accuracy! - 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.

### ⭐⭐⭐⭐⭐ Yolink hub and temp sensor
*by T***T on January 12, 2026*

I'm using this with a Yolink temperature sensor in a hot tub, so that I am alerted if power goes out during freezing temperatures. Very easy to set up, temperature sensor was easy to calibrate for accurate readings, works perfectly for this purpose.
