Smart Outdoor Temperature & Humidity Sensor, Hygrometer, Thermometer, 1000' Long Range, 2 Years Battery Life, Emails, Text/SMS, App Alerts, Alexa, IFTTT Integration. Hub Required!

I bought several of these Yolink temperature sensors and they all work fine and are very accurate. They work with or without the hub but they work much better with the hub. I unplugged the hub for awhile thinking I didn't need it but then i had sensor disconnecting randomly so I plugged the hub back in and all the problems disappeared. So yes, you need the hub to be happy with these. And the hub is cheap and tiotally plug and play so no worries. And they're so easy to set up even grandma can do it.

I've got lots of YoLink devices, including the water leak sensors, automatic water shut off, a temperature sensor for my pool, infrared remote controller, and more. The hardware and software is really good. Yes, you may think "why should I pay this much for a temperature sensor?" I learned the hard way. I wasted a lot of money on Govee ones with the worst battery life ever. Yes, I saved on the price up front but I have to replace the batteries every 2 or 3 months. And those ones aren't even connected to the internet! Instead, with YoLink, the batteries last for years and the devices are connected to the internet. If you want alerts for a specific temperature threshold you can do that easily, and no matter where in the world you are, as long as your phone has a signal, you'll get an alert. Great products and are priced fairly for what you get. In this picture you'll see the waterproof temp and humidity sensor. I have it hanging up in a spot outside my house, that doesn't get direct sun, or rain. The YoLink hub is necessary but you only need one of those for all your devices. That's the secret sauce and why the signal range is so good and the batteries last a long time, as they use "LoRa" protocol.

YoLink products are great. The range is far superior to anything else. Integrates with Alexa very easily--you can just ask her what the temperature is. I have several of these and none have failed...nor has any of their other products I've installed. Temperature seems accurate with other devices I've compared them with. Have to install their hub...which connects to the web via WiFi or Lan. Batteries last for quite a long time...some of my devices have been in use for over a year with plenty of battery life to go.

The YoLink Temperature & Humidity sensor has really met my needs well, allowing me to monitor temperature outside and in my greenhouse. Their app does a great job displaying current and historical data. And so far I've been pleased by the support from the company. When I first set up my greenhouse, I got a Meross sensor because I've liked other Meross products, but very quickly I had issues with the sensor disconnecting from the base unit, so I ended up returning it. I wanted a product that was reliable, but one that didn't cost a hundred bucks. I hadn't heard about YoLink and wasn't sure about the brand, but it seemed like a decent choice. Having got this initial base/sensor package, I've found it very reliable and have expanded the number of sensors reporting back. In my opinion the long battery life of AA batteries is better that a solar/non-replaceable battery other brands use. I will likely buy other YoLink products in the future.

I have both indoor and outdoor sensors! Easy to set up and I have not had one problem with it. Great app easy to use and sends me notifications based on my settings. Highly recommend Youlink!!

These are not “worthless” but they are of little worth and a terrible value. I bought a bunch of Yolink stuff a couple of years ago. The Hub works fine, the INDOOR camera, is acceptable. The switching out let has worked as well. These temp senders are a joke. The ones I have indoors work pretty well. Those outside are junk. The specs say they have a temp range of -22 to 130. They actually do pretty well in the summer but the cold side is WAY wonky. This morning it was 19f and these all red 8-9 degrees higher. Given that they are a couple of years old and near or at their end of battery life window, i decided to change those. Guess what? YOU CAN’T. The cases are sonic welded together. The amount of forc e required to get to the 2 aaa batteries causes so much stress on the unit it now reads 40 higher than ambient. And I was careful. This will also be the case with all the indoor units as well. Ohhh….and I am still waiting for the OUTDOOR cameras they have been promising for years. Buy someone else’s product.

The YoLink Temp and Humidity sensor works very well. Great reliability and set up was a breeze.

Good temperature range which is important in Phoenix. I'm somewhat disappointed in the accuracy. After measuring it against a calibrate thermometer, I find it is only accurate to + or - 5 degrees. But it is still good for relative temperature and will track a trend good enough for my use. The hub is very easy to set up and they have good customer support

Great product.

Comprei para acompanhar a temperatura na casa das montanhas. Perfeito!! Com o Hub da Yolink tenho em tempo real a informação, à distância. A interface me dá a temperatura, umidade e o ponto de orvalho. Toda a configuração foi fácil de ser feita. Se está querendo acompanhar essas informações à distância, RECOMENDO DEMAIS.

I bought this to monitor the temperature and humidity in our attic. I already have the YoLink hub so connecting this sensor to the system took less than a minute. I get live readouts on my phone wherever I am and I can set high/low temperature and humidity level alerts if I want. I've had door and window sensors for 2 years now and still on the original batteries. I can also monitor the remaining battery life of each sensor on my phone.

Very accurate and easy to setup. For now, it's outside at mild temperatures 3 C and works great. Also reports humidity levels. I placed it at a spot of my house (west side) so it does not get direct sunlight and provides "real" temperature readings.

Ce produit fonctionne comme décrit. Excellente qualité. Je recommande fortement.
