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

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.

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.
