Managing indoor temperature and humidity is key to creating a comfortable and healthy living space. The SMATRUL WiFi Temperature and Humidity Sensor offers a simple and affordable way to monitor these conditions in real-time. With a compact design and clear display, it fits easily into any home or office environment.
Unlike traditional monitors, this device also links to smart home systems like Amazon Alexa, Google Home, and Tuya Smart Life. Based on your home’s conditions, it can trigger other devices, like air conditioners and humidifiers. While it keeps things simple, it adds handy features like alarms and data recording.
Simple, flexible design that fits anywhere
The SMATRUL sensor keeps the design clean and simple. Its small square body measures just 5.6cm by 5.6cm and has a depth of 2.3cm. This makes it easy to fit on a shelf, desk, or bedside table without getting in the way. A built-in bracket on the back allows you to adjust the angle to tilt the display for better viewing, depending on where you place it.
The front features a clear LCD screen that shows the temperature, humidity, battery life, WiFi connection, and time. One thing that stands out is the wide viewing angle. Compared to similar models, the display remains readable even when viewed from the side, making it much more practical for daily use around the house.
The top of the unit houses a single button. This button is used to pair the device with your phone app and activate the backlight, which stays on for around 10 seconds once pressed. The button feels responsive and sturdy, offering a satisfying click when used.
Overall, the minimalistic, white exterior looks modern and blends well with most home interiors. The simple, compact design makes it suitable for all kinds of settings—whether a smart home setup, a child’s room, or even a small office.
Reliable performance with good measurement accuracy
The sensor delivers quick and accurate readings for both temperature and humidity. It supports a temperature range from -10°C to 55°C and a humidity range from 10% to 90%. It reacts quickly to changes in everyday use, with updates visible on the screen and through the app.
When placed beside Xiaomi and IKEA hygrometers, the SMATRUL sensor measured a difference of only around ±0.5°C for temperature and ±5% RH for humidity. This is acceptable for consumer-grade devices and shows that the readings are reliable enough for practical daily use.
The WiFi and Bluetooth dual-mode connection is a practical addition. It speeds up the initial pairing process and ensures the device remains connected and more stable. Once paired, the sensor regularly reports data, even if minor changes provide real-time tracking without noticeable delay.
One of its valuable features is scene linkage. Through the Smart Life or Tuya app, the sensor can trigger smart scenes when certain conditions are met. For example, if the room temperature exceeds 30°C, it can automatically switch on a linked air conditioner (with a separately bought WiFi IR remote). Similarly, it can activate a humidifier if the humidity drops below 68%.
Handy app support with alarms and offline reminders
The Smart Life app brings a lot of value to this little device. You can monitor real-time temperature and humidity readings remotely, even when you’re away from home. Historical data is recorded and displayed in simple charts, making spotting patterns over days or weeks easy.
Alarm management is another strong feature. You can set upper and lower thresholds for both temperature and humidity. When the readings go beyond your set limits, the device sends an alert to your phone. This is especially helpful if you look after sensitive items, like wine collections or musical instruments, where stable conditions matter.
If the device goes offline, the app will notify you after about 30 minutes so you can take action. This prevents long periods of lost monitoring, a thoughtful touch often missing from lower-end sensors.
Pairing the device with the app is simple. Turn on WiFi and Bluetooth on your phone, press the button on the sensor for about five seconds, and it will be detected automatically. The setup process usually takes less than two minutes, even for beginners.
Practical features that make a real difference
One of the small but handy features is the backlight function. Although it only stays lit 10 seconds after pressing the button, it makes it much easier to check the display at night without disturbing your sleep environment with a strong light.
The sensor also offers the ability to switch between Celsius and Fahrenheit. The app efficiently manages this, depending on your preference or regional habits. The switching is quick, although the refresh speed might vary slightly depending on the app settings. Another positive detail is the sharing function. You can share the device control with family members via the app so everyone can check the temperature or humidity and receive alerts. It is convenient for families where multiple people may need access to environmental information.
The verdict: SMATRUL WiFi Temperature and Humidity Sensor
The SMATRUL WiFi Temperature and Humidity Sensor is a compact and practical tool for anyone wanting better control over their indoor environment. Its real-time updates, innovative linkage capabilities, and easy integration with major smart home platforms stand out.
While it keeps things simple, it offers enough features to make it genuinely useful—from responsive alarms to app-based data logging and device sharing. Its small footprint and sleek design allow it to blend into any room, while the WiFi+Bluetooth dual mode ensures fast and stable connections.
You might wish the backlight lasted a little longer or included batteries out of the box, but these are small compromises considering its overall price and performance. If you are looking to improve your home’s comfort, monitor special collections, or simply want a smarter way to manage temperature and humidity, this sensor offers excellent value.
