Best SmartThings Humidity Sensor for Your Smart Home in 2022

Trying to find the finest SmartThings humidity sensor on Google yields outdated information and devices that are no longer supported. The SmartSense temperature/humidity sensor has my attention.

In the face of frustration, I resolved to do my own study in order to fill the hole in my knowledge.

In truth, there aren’t many SmartThings humidity sensors that are actually compatible.

But there are some.

Humidity sensor for SmartThings

The Aeotec Multisensor 6 is the finest SmartThings humidity sensor.

If you don’t know what I’m referring about, let me explain.

Relative Humidity (RH)

Smart humidity sensors compare the actual quantity of moisture in the air with the maximum amount that might be present in the environment.

Humidity levels are influenced by temperature.

Relative humidity is a measure of the quantity of moisture in the air compared to the maximum amount of moisture that might exist at a given temperature (or RH).

Because of this, the relative humidity (RH) reading is expressed in percentages. If the percentage of moisture in the air drops to zero, it signifies that it is exceedingly dry. It signifies that the air is saturated to the point that mist or dew is imminent. The optimal level of humidity in your house for overall health and comfort is roughly 40% (with a margin of error of around 20%).

Source: Having too much or too little humidity in your house may have negative effects on both your health and your property. Mold and mildew may form if there is too much moisture in the air. Your sinuses will be affected if the air is too dry.

Keeping a close eye on the humidity levels in your house is essential to ensuring that your family is comfortable.

1) Aeotec Multisensor 6

The Aeotec Multisensor 6 is the ideal SmartThings humidity sensor for this application. This sensor, which utilizes Z-Wave Plus technology, monitors and reports on motion, humidity, temperature, light, ultraviolet light, and vibration.

In terms of precision, the humidity sensor can measure from 0% to 100% RH. Based on Aeotec’s evaluations and specifications, this SmartThings humidity sensor is one of the most accurate out there.

With wireless manual calibrations for temperature, humidity, light, and UV readings, this sensor may be calibrated in any environment for even higher precision.

Just 1.8in wide, the sensor may be mounted on a shelf or bolted into the wall. You won’t even see it since it’s so little.

The CR123A battery in MultiSensor 6 or a USB connection may power the device. The projected battery life is roughly two years if you use batteries.

In the long run, the Aeotec Multisensor 6 is more expensive, but humidity sensors are worth the extra cost.

Aeotec Multisensor 6 SmartThings humidity sensor may be purchased on Amazon if you are interested.

2) NSG-AB-03 Smart 2-in-1

Temperature and humidity are both measured by the NSG-AB-03 Smart 2-in-1 Sensor, which also employs Z-Wave Plus technology.

While the Aeotec Multisensor 6 has four extra sensors (motion, UV, light, and vibration), you get two distinct sensors that you may position in various parts of your house.

The Aeotec Multisensor 6 is somewhat larger, but this 31 inch slim sensor is rather compact and will probably blend in nicely.

Syncing with SmartThings should not cause any serious problems. ‘ SmartThings recognizes this sensor as the Aeotec Multisensor 6, which is a little annoyance. SmartThings will continue to report temperature and humidity even if something occurs.

The range of these gadgets has been a common gripe. Any restricted range concerns you may have may be solved if you have additional Z-Wave devices nearby.

The NSG-AB-03 2-in-1 SmartThings humidity sensor is available for purchase on Amazon.

3) The ZOOZ 4-in-1 Sensor is available.

The ZOOZ 4-in-1 Sensor is the last Z-Wave Plus-enabled sensor on our list. Temperature and humidity are also being monitored this time around.

Because SmartThings doesn’t support this sensor out-of-the-box, I’ll put it at the bottom of my list.

If you’re tech-savvy enough and can follow simple instructions, this shouldn’t be a problem if you have a device handler. This may be a step too far for others.

As long as I haven’t put you off, this humidity sensor will be really pretty reliable. The reporting criteria for humidity, temperature, light and motion may be adjusted to meet your specific requirements.

To ZOOZ’s credit, they replaced the AAA batteries of ver 1.0 with a new CR123A, improving the device’s battery life by a substantial amount.

Despite its little size, the gadget is quite durable.

SmartThings humidity sensor, ZOOZ 4-in-1 Sensor may be purchased on Amazon if you are interested.

Uses for humidity sensors

Humidity levels in certain areas of your house, such as bathrooms, bedrooms, and kitchens, are typically too high, while others are too low.

It is possible to automate dehumidifiers and humidifiers with your SmartThings humidity sensor by monitoring the humidity level incrementally.

Suppose that your humidity sensor indicates that the level of humidity in your bedroom has decreased to 10%. Your smart plug, which is hooked into your humidifier, is activated when your automation senses this low humidity measurement. The humidity sensor informs the smart plug to switch off when the humidity level reaches, say, 35%.

For ultimate comfort, you can monitor and manage the humidity levels in your house using automations like these.


In 2021, finding a SmartThings-compatible humidity sensor might be a struggle. There are a number of things that don’t function well with SmartThings out there.

For those searching for a hassle-free setup and a quality device, the Aeotec Multisensor 6 is the best SmartThings humidity sensor available.

We’d want to know which humidity sensor you prefer.
