Today, let’s take a look at something drastically different. This is the Xiaomi Smart Sensor Set. It is made to work with the Mi Home app and comes with a few different sensors in the box itself. Let’s explore together in this review video.

Before we proceed, this sensor set is now available for sale for the price of RM329.

To talk about the Xiaomi Smart Sensor Set, we have to first start to talk about the contents of the box itself. You get two door/window sensors, two motion sensors, a button, and also a control hub. I should also mention that everything here – minus the control hub – comes with a piece of adhesive behind. That means you can stick it anywhere you like.

Those two pairs of sensors are pretty self-explanatory as they are just sensors on their own. The door/window sensor works by magnetically detecting if the other part is near the sensor or not.

Then, the motion sensors are pretty much as the name suggests – it detects motion. Throughout our test, the motion detection sensitivity is somewhat a hit or miss. In the video, we encountered a bit of an issue in its detection too. Rather intriguing, to say the least.

The main button that comes with this Xiaomi Smart Sensor Set is just a button on its own. It is obviously, programmable in the Mi Home app.

Last but definitely not the least, the Xiaomi Smart Sensor Set has a main control hub. Without this hub, the sensor kit just won’t work.

How the Xiaomi Smart Sensor Set works

As mentioned in the video, the entire sensor set works via Zigbee protocol. That means it needs to send data to a central hub to do al the communications with other devices via WiFi or the internet – hence the main hub’s necessity.

However, as we have reviewed in the Philips Hue light set, these sensors will only work if they are close enough with the main hub. Go too far off and the sensors stop communicating with the main hub, rendering them useless.

That also means everything will have to be in relatively close proximity, or perhaps in the same room. Going through a layer of concrete – maybe a wall or a floor – will degrade the connection strength and have an unreliable sensor.

All of the sensors here will show up in the Mi Home app when it is connected, so you can perform all the programming and monitoring of sensor logs on that app itself.

Programming the Xiaomi Smart Sensor Set

Coming to the software side of things, I feel like this is where Xiaomi needs to improve the most. The sensors themselves are great in terms of hardware – but its detections are not utilized properly through the software.

There are a total of two modes of operation for the Xiaomi Smart Sensor Set. There is an alarm which you can toggle on or off, and that changes the functionality of the sensors. By default, these are its features.

Alarm off (default) Alarm on
Button (single press) Toggles main hub ring light
Button (double press) Turns on alarm mode Turns off alarm mode
Motion sensor Sends notification to phone Rings the alarm
Door/window sensor Sends notification to phone Rings the alarm

These are the “triggers” that allow you to configure the Xiaomi Smart Sensor Set however you want. As shown in the video, I programmed the motion sensor to turn on the lights for 1 minute when motion is detected. Despite its reliability, the task did work.

They don’t always work…

But the biggest issue I have here is the lack of communication between the Mi Home and Yeelight app. As shown in the video, I can reprogram the button to do the tasks I want it to do – but I can’t change it to a specific color. I can either trigger a specific scene with the preset colors, or just turn then on or off upon sensor triggers.

It’s quite limited in a sense that all it can do now is run Yeelights off of specific scenes. It can’t even enter flow mode when the sensors are triggered.


Being a smart sensor kit, there is only one main control hub. This hub must be plugged into the power source. But, the sensors can’t be too far away from the control hub too, as the connection between the hub and sensors might be too weak and fail to send trigger pings.

That means the entire Xiaomi Smart Sensor Set will need to be in close proximity. Perhaps in a living room and that’s it.

Is it practical? Maybe. You could use two separate sensors on a single door to really make sure it sets off the alarm. Or maybe have the motion sensor trigger a night light to turn on so you don’t have to walk in the dark.

I have to mention one thing – I showed and demonstrated the Xiaomi Smart Sensor Set to a few visitors and they were all unfazed by the main hub’s alarm. It sounded like a child’s toy as it is too quiet and doesn’t sound serious at all. Also, anyone can disable this sensor set entirely by just cutting off the main power source. 🤷‍♂️

Wrapping up the Xiaomi Smart Sensor Set

For RM329, I still think smart home security is still too early in its infancy stage to adopt. While I can see the potential in the sensors included in the Xiaomi Smart Sensor Set, the limitation posed by the hub and the software are two major hurdles that Xiaomi has to somehow overcome.
