In this age of cheap Chinese garbage, Amazon junk listings, fly-by-night companies, and generally low quality products, it was a REAL TREAT to come across this company and its products. In fact, this product exceeded my expectations by so much that I was half-expecting something terrible to happen, like it bursting on fire or something similar.Firstly, every one of the products I bought, (shut-off valve, hub, 3 water leak sensors, 2 outdoor temp sensors for freezers, and 2 indoor temp sensors for environmental control), are SOLIDLY MADE. You can feel it in your hand, and it's a feeling that's getting rarer and rarer these days for consumer goods. They're well-made and just SOLID, with absolutely nothing feeling cheap at all.All of the devices went into my freezers, attic, and garage without issue.When I got to the software, that's where I really expected there to be problems, since many of these "smart" companies aren't very smart at all, and they don't seem to test their apps for user-friendliness before releasing them. However I was amazed at how simple it all really was. Getting the hub online, adding devices to it, creating rooms, configuring alarms, etc, all of it was quick and absolutely painless. The only real quibble I could have, (and it isn't much of one at all), is that the alarm section took a moment to figure out. But within a ridiculously short time I had all the devices added and their operating parameters set. Perhaps another helpful note - when you turn on a device for the first time, give it a full minute to link up to the hub. If you don't, the device will add to the hub but it will show as offline, and won't appear to ever come online. After doing that twice, (adding the device within a few seconds of turning it on), I then waited a few for the rest and they added without issue.All of my testing, (temperatures turning on fans and heaters, water leaks activating the valve, etc), all passed with flying colors.All in all, this just feels like money well spent, and YoLink has become one of my favorite companies. Highly recommend.

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 recently purchased the YoLink Weatherproof Fluid, Air, Surface Extreme High/Low Temperature Sensor with Probe, and I couldn't be more satisfied with my decision! This sensor has exceeded my expectations in every way.First off, the installation was a breeze. The instructions were clear, and within minutes, I had it set up and running. The weatherproof design is a game-changer, allowing me to use it outdoors without worrying about the elements.What truly impresses me is the accuracy of the readings. Whether I'm monitoring the temperature of my outdoor equipment or checking the conditions in my greenhouse, this sensor provides real-time data that I can trust. The extreme high and low-temperature range is perfect for my needs, and the probe is incredibly sensitive, ensuring I get precise measurements every time.The YoLink app is user-friendly and allows me to monitor temperatures from anywhere. I love receiving alerts on my phone when temperatures reach critical levels, giving me peace of mind.Overall, I highly recommend the YoLink Weatherproof Temperature Sensor to anyone in need of a reliable and accurate temperature monitoring solution. It’s a fantastic investment that has made my life easier and more efficient!
