Xiaomi has introduced the Smart Display Switch 2, a new smart home wall switch that combines a small color display with four physical and wireless control buttons. Announced on October 28, 2026, the device is now open for crowdfunding reservations in China, with the campaign scheduled to begin at 10:00 AM on November 4.
The Xiaomi Smart Display Switch 2 starts at 159 yuan and will be available in two finishes: white and Space Gray. Unlike Xiaomi’s larger smart home control panels, its display focuses on showing useful information rather than providing a touchscreen interface for controlling connected devices.
The new model is designed to make everyday lighting control more convenient while adding at-a-glance information and programmable smart home functions to a conventional wall switch.
Xiaomi Smart Display Switch 2 Features a Slim Design and Color Screen
The Xiaomi Smart Display Switch 2 adopts an ultra-thin 7.9mm front panel with a composite organic glass finish. Its minimalist appearance follows the design language of the Xiaomi Smart Switch 2 series, allowing multiple switches to be installed side by side without creating a visually inconsistent wall layout.
Buyers can choose between white and Space Gray to match different interior styles.
The built-in color display supports more than 10 themes, giving users several options for customizing its appearance. When paired with a compatible Bluetooth Mesh gateway, the screen can display information such as the time, date, and weather.
Users can also customize the names assigned to individual buttons and change them remotely. This makes it easier to identify each control, particularly when the switch manages several lighting circuits or smart home scenes.
One important distinction is that the screen serves as an information display rather than a touchscreen controller. Users cannot directly tap the display to operate connected smart home devices; control is handled through the physical buttons and configured wireless functions.
Xiaomi has previously introduced similar products through its smart home ecosystem, including the LineHope E8 smart screen display switch, which also features automatic screen activation and four-button controls.
24GHz Radar Automatically Activates the Display
To make the switch more convenient to use, Xiaomi has equipped it with a 24GHz millimeter-wave radar sensor and an ambient light sensor.
The radar supports a 90-degree wide-angle detection range, allowing the display to turn on automatically when someone approaches. This reduces the need to press a button simply to check the information shown on the screen.
The ambient light sensor adjusts screen brightness according to surrounding lighting conditions. In brighter environments, the display can remain easier to read, while lower brightness in darker rooms helps reduce unnecessary power consumption and visual disturbance.
These features allow the Xiaomi Smart Display Switch 2 to function as both a lighting controller and a small information panel without requiring the display to remain at full brightness continuously.
Four Buttons Combine Physical Lighting and Wireless Scene Controls
The four-button layout is one of the product’s main functional features. Xiaomi divides the controls into two sections, with different roles assigned to the upper and lower buttons.
Two Physical Buttons for Independent Lighting Control
The bottom two buttons are connected to physical relays and can independently control two lighting circuits.
This arrangement allows users to operate two sets of lights from one wall-mounted device. It also enables compatible conventional lighting to become part of the Xiaomi smart home ecosystem through the Mi Home app.
For households that want to introduce smart lighting without replacing every existing light fixture, this approach offers a practical way to add connected control while retaining familiar physical switches.
For users looking to upgrade their existing lighting setup, Xiaomi also offers other options, including its Xiaomi Smart Switch, which supports smart home integration and single-fire or neutral-wire installation.
Two Wireless Buttons for Smart Home Scenes
The upper two buttons work as wireless scene switches rather than conventional relay-based lighting controls.
Each button supports single-click, double-click, and long-press actions. Through the Mi Home app, users can assign these gestures to different automation routines.
For example, a configured button could activate a homecoming scene that turns on selected lights, or trigger an away mode that switches off designated lighting and runs other compatible smart home automations.
The wireless scene-control functions require a compatible Bluetooth Mesh gateway. Users should also confirm that their connected devices and automation settings support the actions they intend to configure.
Single-Fire and Neutral-Wire Compatibility Reduces Installation Limitations
A notable feature of the Xiaomi Smart Display Switch 2 is its support for both single-fire and neutral-wire installation configurations.
Traditional color-screen smart switches may require a neutral wire to supply power to their displays. That can complicate installation in homes where the existing wall wiring only provides a live wire at the switch location.
Xiaomi addresses this limitation with a built-in lithium battery-based energy storage system. In single-fire mode, the device collects energy while the lights are on and uses stored power to operate the color display.
According to Xiaomi’s calculations, keeping the lights on for more than 10 minutes per day should be sufficient to maintain the automatic screen-activation function under the stated operating conditions.
If the stored energy becomes insufficient in single-fire mode, the display functions may be affected. However, Xiaomi says the switch’s manual operation and smart control functions will continue to work.
This distinction is important for buyers considering the product for an existing home. Although the switch supports single-fire wiring, installation requirements and available functions should still be checked against the home’s electrical setup.
Xiaomi Mesh 2.0 Promises Faster Responses
The new switch incorporates Xiaomi’s Mesh 2.0 module. According to the company, the updated system improves response speed and reduces network setup time compared with the previous Mesh 1.0 generation.
For a smart home switch, these improvements could make interactions with connected devices and configured automation scenes feel more responsive.
However, actual performance will depend on the surrounding network environment, gateway compatibility, and the other devices involved in each automation routine.
Users planning to connect the switch to an existing Mi Home setup should check gateway compatibility before purchasing, especially if they intend to use the wireless scene buttons.
Magnetic Relay Rated for One Million Switching Cycles
Xiaomi has also focused on the switch’s mechanical and electrical design.
The Smart Display Switch 2 uses a latching relay combined with dynamic adaptive zero-crossing detection. The company rates the relay for up to one million switching cycles.
This rating provides an indication of the relay’s intended durability under the manufacturer’s test conditions. Actual service life can vary depending on electrical loads, installation quality, and operating conditions.
The combination of physical lighting controls, wireless scene buttons, and a customizable color display gives the device a broader role than a conventional wall switch while retaining familiar button-based operation.

Is the Xiaomi Smart Display Switch 2 Worth Watching?
The Xiaomi Smart Display Switch 2 takes a different approach from a full smart home control panel. Rather than relying on a large touchscreen, it combines a compact information display with physical lighting controls and programmable wireless buttons.
Its strongest selling points are the slim 7.9mm design, automatic screen activation, support for two independently controlled lighting circuits, customizable smart home scenes, and compatibility with single-fire wiring.
The energy storage system is particularly relevant for homes where adding a neutral wire would otherwise complicate installation. Meanwhile, the four-button arrangement gives users direct control over everyday lighting while keeping frequently used automations within easy reach.
At a starting price of 159 yuan, the device could appeal to Xiaomi smart home users who want more functionality from a wall switch without installing a separate control panel. Its overall value will depend on the final crowdfunding price, gateway requirements, wiring compatibility, and the availability of the product outside China.
