## Description

desertcart.com: YoLink Weatherproof Fluid, Air, Surface Extreme High/Low Temperature Sensor with Probe, 1/4 Mile Long Range, YoLink Hub Required : Industrial & Scientific

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.
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.

## Features

- VERY VERSATILE: many applications, including pool/hot tub & fish tank water, wood boiler, fridge and deep freezer, livestock water trough, milk, beer, wine, water, steam and pipe temperature monitoring. Additional uses include composting, HVAC/heating/cooling/ventilation management (YoLink smart plugs and switches purchased separately).
- THAT WAS EASY! After the hub is set-up, adding new devices takes just a couple minutes with our app's convenient and lightning-fast Scan & Play QR code scanner. No more waiting for WiFi! Installation can be as simple as hanging the sensor on a nail or command hook, or by placing on or inside the box or enclosure to monitor.
- KNOW NOW: be informed immediately of off-normal conditions when you easily set up one or more optional notification methods, including SMS*, phone push notifications, emails, siren and/or SpeakerHub audible notifications for your home or business. *Each YoLink app account receives 5 free SMS per month per device plus five. Additional 200 or 500 SMS are available for 2 and 5 dollars per month, respectively. There are no required subscriptions and the app is always free.
- NO WIFI WORRIES! And no WiFi required! YoLink utilizes a unique wireless format very different from WiFi. Based on LoRa, our devices boast 1/4 mile open-air wireless range, long battery life, and superior obstruction penetration (allowing for placement inside freezers, etc.). Communication is two-way encrypted, protecting your network security and privacy.
- START SMART! A YoLink hub is REQUIRED for full functionality, including for the app to work, but your hub is compatible with a growing family of smart products for home and business, from smart locks to smart light switches and more! Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.

## Questions & Answers

**Q: Can the entire sensor unit be submerged in the pool? Not just the cable part?**
A: No, just the cable. We have plans to make a floating sensor for pools, but until then, you need to put the sensor where it will not be submerged. This is not a fully company-encouraged solution but some customers put these in a tupperware style sealed container, drill a hole for the probe, caulk that up, and leave it to float in the pool or hot tub. It's a little DIY and not the best solution but I wanted to share that with you in case that might be an option for you. 

Enjoy!

Eric with YoSmart

**Q: Can this be used to measure temp inside a chest freezer? Will signal get out of the chest freezer?**
A: I have this YoLink model inside my chest freezer and refrigerator:
Smart Wireless Temperature / Humidity Sensor Wide Range (-22 to 158 degrees) for Freezer Fridge Monitoring Pet Cage/Tank Monitoring Smartphone Alerts, Works with Alexa IFTTT, 2 Pack - Hub Included
The model you’re asking about, I have one outside and one in my garage. 
The model in my freezer and refrigerator works great. If you already have a hub, I don’t see why the model you’re asking about wouldn’t work inside a freezer.

**Q: How to replace the two AAA batteries?**
A: Remove 4 small rubber "pads" at the corners. Remove 4 small Phillips screws. Remove cover. Replace batteries. Reinstall.

**Q: Can I put this inside a water reservoir to detect when the water reaches a certain height?**
A: We actually have a Water Level Monitoring Sensor that would be much better for your application. It comes with a water-sensitive probe, and the sensor can also work with standard float switches. It's not available now, but before too long we'll also offer a float switch as an accessory.

### ⭐⭐⭐⭐⭐ 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.
