YoLink Smart Outdoor Temperature Humidity Sensor Hygrometer Thermometer 1000 Long Range 2 Years Battery Life Emails Text SMS

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.

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. Read more

Yolink sensors are simple to use and network the software works very nice and is just what we were looking for when we leave home for mid winter vacations our house is fully monitored for water leaks, low temps and unintended motion...The yolink system is simple to set up on your smart phone... email or text messages are easy to set up so you get a notice if any sensor set goes out of range.

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. Read more

Bought 11 months ago, and has worked flawlessly up until now. Manual well written with troubleshooting guide. Tried everything and could not get it to work. Reached out via email to customer service. Within 15 minutes got return email asking for the unit id. Replied back about an hour later. 10 minutes after that, customer service explained they are shipping out a new unit today. No fuss. This is what customer service is all about and SO REFRESHING to deal with a company that cares and replies so quickly. They have a great variety of sensors a few I have bought. App layout very user friendly. Bravo! Read more

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. Read more

I purchased this heat sensor for my generator enclosure. I have heard horror stories about people's (including my neighbor generator) generators over heating and stop working due to the cooling/exhaust fan stopping working. The enclosure just requires a single cooling/exhaust fan. I had two installed. They both do not run at the same time. One is for a backup. Using this sensor, it monitors the temperature in the enclosure. If it start over heating (user adjustable). I get notified a high temperature warning for my generator enclosure on my phone. At the same time, the second/backup fan is automatically turn on. So I do not need to do anything. Please note that go be notified and for any type of automation, the Yolink hub is required. The pros of Yolink and their devices. 1) Easy setup, using the app, scan the QR code on the device and it is added. You can change the name of the device if needed (highly recommend) 2) The great customer service. Regardless if it is a question, issue (have not had any so far) or even a suggestion, a REAL, living/breathing person will respond to you. 3) The large variety of devices and sensors they offer. 4) The ability of the devices and sensors to interact with each other via the hub and with Alexa and the devices linked to Alexa, again via the Yolink hub. As far as any Cons: I have not found any yet. Read more
