Best SmartThings Humidity Sensor for Your Smart Home in 2023
A quick Google search for the best SmartThings humidity sensor results in a lot of outdated information, and products that are no longer being made or supported. I’m looking at you, SmartSense temperature/humidity sensor.
After a bit of frustration, I decided to fill this void by doing some in-depth research of my own.
The reality is, there just aren’t that many truly compatible SmartThings humidity sensors out there.
But they do exist.

Best SmartThings Humidity Sensor
In short, the best SmartThings humidity sensor is the Aeotec Multisensor 6. But before I get into exactly why that is, let’s cover some basics.
Relative Humidity (RH)
Smart humidity sensors measure the amount of humidity in the air, compared to how much there could be. Temperature is what determines how much humidity there could be.
The ratio of moisture currently in the air, to the highest amount of moisture there could be at a particular air temperature, is called relative humidity, (or RH).
So RH is measured, and reported, as a percentage. 0% means the air is extremely dry. 100% means that the air is so moist that mist or dew is about to form. The ideal relative humidity in your home, for overall health and general comfort, is right around 40% (+/- 20%).
Too much or too little humidity can cause problems in your home and your health. For example, too much humidity will lead to mold growth. Too little humidity will cause your sinuses to suffer.
That’s why it’s important to constantly measure the humidity in your home and make any necessary adjustments.
1) Aeotec Multisensor 6
The best SmartThings humidity sensor for the job is the Aeotec Multisensor 6. This sensor uses Z-Wave Plus technology to monitor and report motion, temperature, humidity, light, UV, and vibration.
The humidity sensor has an RH range of 0% to 100% and an accuracy of +/- 5%. Based on reviews and the specs Aeotec provides, this is one of the most accurate SmartThings humidity sensors out there.
For even greater accuracy, this sensor can be calibrated for every room and every environment with manual calibrations wirelessly available for its temperature, humidity, light, and UV measurements.
The sensor itself is super small (just 1.8 inches across) and can be placed on a shelf or screwed into a wall. Because it’s so small, you won’t even notice it’s there.
MultiSensor 6 can be powered by its CR123A battery or a USB cable. If you chose to power it with batteries, the estimated battery life is about 2 years.
Ultimately you’ll pay a bit more for the Aeotec Multisensor 6, but with humidity sensors, you really do get what you pay for.
If you’re interested in purchasing the Aeotec Multisensor 6, SmartThings humidity sensor, you can buy it here on Amazon.
2) Centralite Temperature and Humidity Sensor
The Centralite Temperature and Humidity Sensor also uses ZigBee technology to measure both temperature and humidity.
While you don’t get the additional 4 sensor capabilities (motion, UV, light, vibration) the Aeotec Multisensor 6 offers, you do get the temperature sensor capability as a bonus!
A bit larger than the Aeotec Multisensor 6, this ‎3.5 x 3.46-inch sensor is still quite small and will likely blend in well.
When syncing with SmartThings, you shouldn’t have any major issues. SmartThings should pick this sensor up with no problem.
A complaint with these devices has been that Alexa doesn’t pick up the humidity readouts. If you’re using Alexa as your home automation “hub,” then this sensor might not be for you. If not, you should be fine.

3) ZOOZ 4-in-1 Sensor
Last is the ZOOZ 4-in-1 Sensor, which once again uses Z-Wave Plus technology. This time to measure motion, temperature, humidity, and light levels.
I’ll start by saying that this humidity sensor is last on my list simply because it isn’t compatible with SmartThings out-of-the-box.
It requires something called a custom device handler and from what I can tell if you’re tech-savvy enough and can follow basic instructions, this shouldn’t be too big of a deal. But for some, this might be a bit too complicated.
If I haven’t scared you off yet, this humidity sensor is actually quite solid. You can change up the reporting thresholds for temperature, humidity, light, and motion, to get precise and unique detection.
There were past complaints about this device’s battery life, but to ZOOZ’s credit, they changed out the AAA batteries of version 1.0 for a new CR123A battery, extending battery life significantly.
The device itself is compact and reliable.

Humidity Sensor Use Cases
Spaces in your home such as bathrooms, bedrooms, and kitchens can be too humid, while other environments are often not humid enough.
You can use your SmartThings humidity sensor for incremental monitoring of humidity, enabling the intelligent automation of fans, motorized windows, dehumidifiers, and humidifiers.
Imagine a scenario where your humidity sensor detects that your bedroom humidity has dropped to 10%. Your automation detects this low humidity reading and triggers a smart plug to turn on, which your humidifier is plugged into, effectively turning on your bedroom humidifier. Once the humidity rises to 35%, the sensor tells the smart plug to turn off.
With automations like this, you can constantly monitor and control the humidity levels in your home for maximum comfort with little to no effort.
Conclusion
Finding a quality-compatible SmartThings humidity sensor in 2023 can be a real challenge. A lot of the products out there are either out of commission or simply don’t work well with SmartThings.
If you’re looking for a hassle-free setup and a quality product, I’ve found the Aeotec Multisensor 6 to be the best all-around SmartThings humidity sensor on the market.
Good luck and thanks for reading!
