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

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.

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.

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!

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

The YoLink hub and sensors work great! A strong solid connection with the hub is maintained by all sensors, and all sensor data is readily viewable in the app. So far, this temperature and humidity monitoring system is superior to anything else I've seen on the market.

Purchased this sensor to monitor the temp and humidity in a 5'X5' outdoor pump house housing a pressure tank and water well head for a water system for a home in extremely rural Northern WI. Pump House is heated with resistance heating on an internal thermostat to prevent freezing, and is well insulated. Sensor detected temperature drop in building when thermostat failure shut down heat - 45-55 degree limit. Outside temp 7Degrees F. Monitor via smart phone app from 257 Miles away via internet connection, provided plenty of time to respond and restore heat. Saved 2-4 Thousand dollars damage had well head frozen, and it would have in planned week absence. Not to mention water running uncontrollably for a week straight. Good sensor, Great system. Great customer support. Have other sensors for this system. All work well and stay functional. If you need and alarm or reporting system this system covers, don't even look elsewhere, just buy this system!! It is that good!!. The company actually calls you back if a tech is not available and you have questions, and they remember who you are over several days. What a Concept!! Refreshing in the chaos of the present day !!!
