YoLink X3 Temperature & Humidity Sensor, YS8006

Yolink products are rock solid. I started off with this single termperature/humidity sensor and quickly expanded to at least 20 other various kinds of sensors over the next few weeks. The sensors are easy to add to your network. You simply open the app, scan the QR code on the sensor, name it, assign a room and you’re done. Sensors are all hyper-responsive and battery life is incredible. The range is likewise great. My farthest sensor is in a chicken coup behind a huge barn several hundred feet away from the Yolink hub. Reception is still great. The automation options built-in are good. There’s room for improvement. For instance, I have a temperature sensor in my office that turns on an AC plug to my air conditioner. The only triggers I can use from my thermometer sensor are high and low temp alert. I define high temp as 75 and so AC kicks on at that threshold. That works well. But I want the air conditioning to turn off at another threshold, say 70 degrees. I would have to define my low temp alert as 70 in order to make that happen. That doesn’t really work for me for several reasons. I’d like to have a heater that kicks on at 55 degrees, for instance. I could do this with two sensors but that seems wasteful. So I’m looking to integrate with ITTT (If This Then That) service to do more finely grained automation. I think it’ll work. Even though the built-in automation isn’t quite there yet, the hardware is so rock solid and awesome that Yolink gets my highest recommendations.

I have several Yolink products and they all are functional and work flawlessly. I use this one in the garage where I have my RV stored and always know what the temperature and humidity is at just a glance on my phone. Hoping for a Yolink camera to be designed and built!

I am a big believer in Yolink products. I have several of 5 different devices, and they have never disappointed. They are connected to Home Assistant via the Yolink hub. Connecting the hub to Home Assistant is quick and easy using the built-in integration. Connecting the devices to the hub is even easier and quicker. The Android app is clean and very easy to use. This thermometer/humidity sensor is attractive with a large, easy to read display. Accuracy seems good and is almost identical across my other thermometers. Another great feature of Yolink products is their long range. I live in a cement block house with steel studs, and my outside YoLink whole house water mains shut-off valve has never lost connection. Add to this list of positives an incredible battery life, and you can see why I always check for a YoLink solution before any others.

Works fantastic. I have several of these in different rooms of the house. This is a large number of leak detectors in critical areas of the basement, AC condensation pump, etc. These YoLink products are affordable and do an incredible job.

Has worked perfectly for months and gives us peace of mind while away that the freezer is still working. The hub is actually pretty far from the freezer in the garage, so we were surprised how well it works. The app works as it should no complaints here

Scan with your phone/tablet camera and boom, added to your Yolink list. My only concern is its durability: We placed this sensor in our greenhouse because it offers ten-minute updates whereas the other Yolink sensor, which is rated for outdoor use, only updates once/hour. We hope this unit will stand the test of time...and heat...and humidity.

Yolink is a great product. My refrigerator/freezer does not give the current temperature, only what it is set at. After a few times of losing food, I decided to get an electronic thermometer that uses an app. After much research, Yolink was everything I was looking for. Connectivity was simple, I get constant monitoring of the fridge and freezer now. Very pleased. Yolink also provides YouTube videos and when you need more help, email or call and they are very responsive. Best of all, their products are affordable. You can link all your products to the their hub.

I use these X3 temperature / humdity sensors in my refrigerators. They track the temperature at a higher frequency (as frequently as once per 10 mins, or 6 times per hour) than the regular YoLink temp/humidity sensors (the regular sensors only track one data point per hour). These X3 sensors still only call home to the hub once per hour, even though they are tracking the intermediate data points every ten minutes. They do a great job contacting the hub reliably from inside the refrigerator cabinets. I also really like that they include LCD screens too, allowing a quick visual check when I open the fridge for normal purposes, without needing to necessarily open the app to also check the temperature and humidity levels. The LCD built into these is far superior to some others I've had in the fridge on non-smart temperature probes; it remains high contrast and easily readable, where those others would tend to fade and be sluggish to refresh. All in all, I really like these sensors. However, I think a more reasonable price would be in the $30-$35 range. $50 msrp / $40 sale price is a little steep for these IMHO.

These sensors are perfect for monitoring the temperature of a fridge freezer located in an outside garage. The YoLink hub is located inside the house some 10 metres away. Setup is quick and easy with one important caveat. Make sure your hub and sensor are set to the same region. I inadvertently bought a second sensor from Amazon UK which is of course set to EU region. My hub and other sensor were bought as a kit on the Amazon US site. You can guess the rest! The support from Yo-Link was excellent but ultimately the attempt to update software for the sensor failed. I gave up, did a return and bought another sensor from the US site.

A little expensive but useful if you wish to monitor the temperature of a room during a heat wave.

This is my fifth yolink device. It's really disappointing. It's the most expensive device I've purchased. I bought it for the ability to check temperatures realtime. When I use it that way, it always says that I can't detect the device. Definitely not worth the extra $. It still does the scheduled temperature check...but not as promised.

Bought this (Model YS8006) as it was advertised to be more accurate than their previous one (Model YS8003) and had less error (RH 2% vs 3%). However, when it arrived, the calibration was way off compared to my NIST certified hygrometer. Putting it through the pure salt + distilled water and damp cloth calibration, this X3 model performed worse than the non-X3 model. And the X3 cannot be calibrated as it exhibited non-linearity (lower than normal at high RH and higher than normal at low RH so no offset value can correct for this). Tech support did not understand the technical issue and offered a canned response which showed they did not read my question. Don't waste your cash on this more expensive version.

Not X3. Only one. It was expensive so I thought I'd be getting X3 of them. You can get 2 and a hub for this price. Pretty slippery dealing. Not worth it.
