Xiaomi’s modern smartphones come with a host of useful features, including its built-in infrared port, which turns your mobile device into a universal remote control that can replace dozens of plastic petals from TVs, air conditioners and audio systems, and users often underestimate this module, even though it allows them to control household appliances without having to search for original remote controls or buy new ones.
The principle of operation is based on the transmission of encoded light signals, invisible to the human eye, but readable by consumer electronics receivers. To start using the IR port, you do not need complex technical knowledge or additional equipment. All the necessary tools are already built into the shell of MIUI or HyperOS. All you need is to properly configure the software and make sure that your smartphone is physically equipped with the appropriate emitter, which is usually located on the upper end of the case.
In this article, we will discuss in detail the process of activating, configuring and optimizing the operation of an infrared transmitter, how to add new equipment, what to do if the remote does not work, and what hidden features the standard Mi Remote application provides. We will also look at alternative solutions for hardware-free models and answer the frequently asked questions that arise from owners of Redmi and POCO equipment.
Checking for an IR emitter on your device
The first step before you start setting up is to physically check for the module on your gadget. Not all budget and mid-range models have this feature, so it's important to make sure it's there so you don't waste time installing broken software. Usually, the infrared port looks like a small black glass on the top of the smartphone next to a noise-canceling microphone or headphone jack.
For visual diagnostics, you can use the camera of another phone. Turn on the camera on the second device, point the top of your Xiaomi to the lens, and press the IR port button in the remote app. If you see a purple or white glow on the screen of the second phone, then the module is healthy and ready to go. Lack of glow may indicate a breakage or lack of hardware.
You should also check the specifications of your model on the manufacturer's official website, which is often referred to as Consumer Infrared or simply IR Blaster on the specifications, and if there is no such item on the list of characteristics, software methods will not help to add a physical transmitter, and you will have to consider external solutions.
⚠️ Note: Do not confuse the IR port with a proximity sensor or notification indicator. the IR emitter usually has a darker, almost black glass and is located strictly on the end face, rather than on the front panel.
Installation and initial configuration of the Mi Remote application
The main tool for managing the app is the Mi Remote app, which is already built into the system in most regions and is located in the Tools folder. If you didn't find the icon on the desktop, it may have been deleted accidentally and can be restored through the GetApps app store or Google Play by searching for "Mi Remote."
Once the app is launched, it needs permissions, the system will request location access, which is required to determine your region and select the current codes for home appliances, and permission to use Bluetooth to search for devices in the neighborhood may also be required, although the IR port itself operates independently of wireless networks.
To add a new device, click on the big plus icon in the program interface. You will be asked to choose the type of equipment: TV, air conditioner, console, fan or projector. After choosing the type, the system will ask you to specify the manufacturer's brand. If your brand is not on the list, you can use the Search function to find compatible profiles by model name.
☑️ Primary remote setting
The key is the code testing phase, and the app will offer a few configuration options for your brand. The IR port setting requires care: press the switch on the smartphone screen, pointing it at the hardware until the device responds. Only after a successful test can you save the profile and give it a name, such as "TV in the living room."
The process of adding and calibrating devices
Adding new techniques often goes automatically, but sometimes manual calibration is required to accurately work all the buttons. Once a brand is selected, the app may suggest a series of tests to check volume, channel switching and menus. If standard codes don't fit, use Manual Search or Auto Search mode, which sifts through thousands of signal combinations.
It is important to consider the distance and angle of inclination when pairing. The optimal distance between the smartphone and the receiver of equipment is from 1 to 3 meters. Direct visibility is mandatory: infrared light does not pass through walls and does not reflect poorly from surfaces, so point the upper end of the phone strictly to the receiving window of the device.
| Type of device | Required data | Difficulty setting up | Frequency of use |
|---|---|---|---|
| Television | Brand, model (optional) | Low. | Tall. |
| Air conditioner | Brand, sometimes model. | Medium | seasonal |
| TV-box | Brand, type of connection | Low. | Tall. |
| Projector | Brand | Tall. | Medium |
For complex devices such as air conditioners, you may need to adjust additional features such as changing the temperature or fan mode. If the buttons are not working correctly (for example, instead of increasing the volume, changing the channel), try to select another code from the list or update the application database through the settings.
Use of additional functions and widgets
The Mi Remote app offers not just button emulation, but advanced use cases. You can create desktop widgets for quick access to frequently used features, such as turning on your TV and switching to your desired one. HDMI-It's especially convenient for the elderly or for children who have a hard time understanding the interface.
Translation allows you to use your smartphone as a touchpad, and by swiping your finger across your phone, you can control your cursor on your Smart TV screen or select content from your menu, which makes typing with your virtual keyboard into a simple, fast action that you can do on a large, user-friendly smartphone screen.
Control of the IR port also includes the ability to create macros. A macro is a sequence of commands executed at a single click. For example, the Kino command can simultaneously turn on the TV, switch the signal source to the console and reduce the brightness of the projector, if your technique supports such commands.
Remedial malfunctions and problems
Despite the reliability of the technology, users can face situations where the remote stops responding. Often the problem lies in the software failure of the application itself. In this case, it is recommended to clear the program cache through the Android settings menu or reinstall the application clean. Sometimes it helps to simply restart the smartphone, which resets temporary driver errors.
If the IR port doesn't work after the system update, check the access rights. In newer versions of MIUI or HyperOS, permissions may have been reset. Go to Settings → Applications → All Applications → Mi Remote → Access rights and make sure that access to the IR port and geolocation is activated. It's also worth checking if the power saving mode is turned on, which can block the background operation of the module.
⚠️ Note: If the IR port stopped working after the phone fell or moisture got in, the problem may be hardware, in which case the software methods are powerless, and a plume or module replacement at the service center is required.
Another cause of failure is third-party remote applications that can conflict with the system driver. If you installed alternative software, uninstall it and check the regular application. In rare cases, resetting network settings, which does not affect personal data, but updates the configuration of system communication modules, helps.
Alternative solutions for smartphones without an IR port
Owners of models that don't have an integrated emitter can also operate the equipment using external adapters, which connect via a USB Type-C or Lightning connector and are relatively inexpensive, operate on the same principle, but require an adapter and can take up a charging port, which is not always convenient.
The alternative is to use a smart home, where if your appliances support Wi-Fi or Bluetooth, you can control it through the Mi Home or Google Home app, in which case the signal is transmitted via the router, not through the IR port, but this method requires that both the phone and the controlled appliances are on the same network or have access to a cloud server.
For those who want versatility, there are universal IR hubs for smart homes, small devices that sit in a room and broadcast IR signals on command from a smartphone over the Internet, which allows you to control the air conditioner or TV even when you're away from home, which is not possible with a built-in IR port of the phone.
