Weatherproof Fluid, Air, Surface Extreme High/Low Temperature Sensor with Probe, 1/4 Mile Long Range, YoLink 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.

I purchased and installed this on a small anchor a mostly hidden feature wall on my in-ground swimming pool. The box sits above the water level, hanging about 8 inches above the top edge of the pool surround, with the wire hanging down into the water. It tracks the pool temperature on an hourly basis, allowing me to see how the pool's temperature is swinging throughout the days. With the amazing range of the YoLink LoRa communication protocol, this thing has NO problems remaining connected with the YoLink hub that's on the other end of the house, on the second floor, in a closet. Beyond working great for tracking water temperature, this unit has proven quite durable and waterproof, surviving deluge level water, including the recent Hurrican Beryl, with no issues (and nicely tracked the roughly 10 deg. F drop in average water temperature brought about by the hurricane). The only downside is the continued requirement that all YoLink devices must have an Internet connection. This sensor will store values when the Internet is unavailable, and then transmit them when the connection is restored, but it would be nice if YoLink would come out with a solution that allows fully local sensor tracking.

I bought my first thermometer for my aquarium and it's been working like a charm since installation. The alerts are great especially when temperature is critical for the animals in my tank, I get notified immediately when temp is outside of the set parameters. Since the base unit is hooked up to Internet, I was notified of a connection loss when I had a power outage when I wouldn't have otherwise known while I was at work. I bought a 2nd one for a daphnia tank and just got my 3rd one today for a brine shrimp setup. The only annoying thing I'd say about this is that you need a password every time you open the app. Not a big deal since I use a fingerprint but it would be great to bypass that. Which brings another point, I wrote to customer service about this and they were very quick to respond which was amazing. I highly recommend these if knowing exact temperature is critical for you, and for the cost it's worth it (which I believe these are very inexpensive, I've seen higher priced devices that don't work as seamless as this).

I uses these in several location to monitor creek temps. They hold up well in hard exterior conditions. Great communication with hub as with all yolink equipment

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.

Setup was unbelievably easy. Works great for the hot tube, will have to see how long it lasts. Got the hub as well, also unbelievably easy to set up

I own several sensors and a hub . This is the best purchase I had made on Amazon . Phenomenal for what it does . I had placed it in wall next to pipes to measure temperature . Sets up in a second and provides accurate reading .

Working perfectly, concrete warehouse installation, setup with home assistant in an hour.

Constantly disconnects from YoLink hub. This is my 2nd unit and they both intermittently disconnect from the Yolink Hub. This type is the only one that does this. All my other YoLink thermometers work flawlessly. This model just doesn't cut it. I use it to monitor the temperature of my livestock water tanks and was trying to use HomeAssistant to turn on the tank heater when the temperature dropped in the tank but this thermometer is so unreliable that I had to use a timer instead.

Je suis satisfait du produit qui est très précis (utilisé environ trois semaines
