Weatherproof Temperature and Humidity Sensor, Hub Required!

haven’t used it yet

Great Addition to My Yolink Hub

I started with Yolink for the leak detection and main water shut off in my house. It was by far the best solution out there. I have since added temperature and humidity sensors to various areas of my house. This was the latest addition, and it works flawlessly, even with the doors closed. Great job Yolink!!

Very Pleased

I was really pleased with the Temperature and Humidity Sensors. They are very accurate and responsive. I have only had to restart the app a couple of times to get the readings. They were also very easy to install and use. I am now thinking of combining these with other YoLink devices to automate my operation.

Monitor Temperature and Humidity Anywhere

YoLink’s industry-leading long range communication allows for placing the sensor

in your out-buildings, separate garage building, barns, greenhouse, etc.

Phone that shows a garage freezer high temperature alert.

Monitor Temperatures

Place one in each room your wish to keep an eye on the temperature and humidity. Monitor the temperature of rooms or buildings without temperature control, for example, receive a low-temp alert before water pipes freeze.

Preventive maintenance

Place the sensor in a basement or other area subject to mold and mildew growth due to high humidity levels. Identify problem areas before expensive repairs are required

Smart Control

Use the sensor and app automation features to automatically turn on the exhaust fan in your bathroom during hot showers and baths or turn the humidifier or dehumidifier on or off based on sensor levels.

What Our Customers Think!

I love these temp sensors and have them all around my home and property…even the dog house!

What I love about Yolink

1. Does not bog down your internet because only the base goes online

2. Amazing wall penetration and signal range

3. Super easy to set up devices

4. The software is relative, easy to understand and use

5. Dependable actions and alerts

6. No monitoring fees

7. Great customer service

I have an underground root cellar and a steel out building about 75 ft from my home which I thought there was no way the motion and temp sensors inside those buildings would be able to communicate with a base inside my home. But to my surprise they did. I was sold. I have since purchased several more motion sensors (interior and exterior), sirens, water leak sensors, thermostats, smoke alarms and some other devices. I purchased these several months ago and so far I am extremely pleased. The devices have been dependable and are not running through batteries quickly. I feel like I have an expensive system, but it was not expensive. Moreover, the customer service is exceptional. I had a question and was able to call and speak to someone knowledgeable and helpful immediately. I am so impressed I have recommended yolink to my family and friends

I studied all the systems out there, THIS is the one you want

I use this inside my dual walk in cooler and freezer. What sets this apart from other similar temp monitors is that you don't need to run a wire out the door to transmit to the base. The signal can travel through the aluminum cooler box walls. It's been running without any issues for many months now, so amazing battery life. Installation and setup was a breeze. The app works great and shows 24 hours history. It can be set to alert via SMS text. No monthly service either. Temp reading seems accurate since they match up to the cooler gauges. When you have thousands of $s in food product at risk, you need 24x7 monitoring. Great value and small price to pay for peace of mind.

Easy set-up and works great!

I bought the YoLink Temperature and Humidity Sensor to automate my whole house fan, in combination with a YoLink mini plug and a new YoLink hub. Setup for all three devices was easy, the instructions were clear and the devices were immediately recognized by the app.

I created an automation to turn on the fan based on time and the high temperature alert on the temp sensor, and a second automation to turn the fan back off. Both have worked reliably so far.

The choices for a temperature monitor (sensor) that can trigger actions, even through IFTTT, is very limited. I was happy to find one that could not only do that, but also included a display AND was very economical. I will definitely order more temp/humidity sensors and wall plugs to further automate my home.
