Modern Xiaomi smartphones often feature a built-in infrared (IR) emitter that turns your device into a universal control center for home appliances. This feature allows you to forget about finding original remotes and combine control of the TV, air conditioner, audio system and even a projector in one application. Owners of Redmi and Xiaomi devices appreciate this option for convenience and functionality, but the initial setup can cause questions for beginners.
The configuration process takes only a few minutes and requires no technical knowledge. You will need only a stable Internet connection to initially download code databases and, of course, the smartphone itself with an IR module. In this article, we will discuss all the stages of configuration, discuss common errors and help you make your phone an indispensable assistant in managing a smart home.
It's worth noting that the quality of the infrared remote is directly dependent on the correct choice of the device model in the database. Don't rush to choose the first code you find if the equipment does not respond. The system offers several options for emulating signals, and finding the right one may require checking 2-3 profiles. This is normal practice, since home appliance manufacturers often change the signaling protocols in different product series.
Checking the presence of an IR port and preparing the device
The first step before installing the software is to make sure that your smartphone is physically equipped with the right module. Not all models in the budget segment have an infrared transmitter, so visual inspection or checking the specification on the official website is a mandatory procedure. Usually the sensor hole is located on the upper edge of the case, next to the noise-cancelling microphone, and looks like a small black dot.
If you are not sure about the hardware component, you can search the system settings or check the list of supported devices on the manufacturer's website. The absence of an IR port will not allow you to use the standard Mi Remote application in emulation mode, although Wi-Fi control will remain available for compatible equipment. For owners of phones without an "infrared" there are external adapters that connect via a USB Type-C or 3.5 mm connector, but they require separate software.
⚠️ Warning: Do not attempt to clean the IR port hole with sharp objects or high-pressure compressed air, as this may damage the sensitive emitter inside the enclosure.
Once you have a module, check the battery power. Although the setup process is not energy intensive, a dead phone may suddenly shut down at a critical time of codebase updates. It is recommended to have a charge above 20% before starting work. Also make sure that the device is geolocated, as some of the functions of region determination and code selection depend on this parameter.
Installation and initial launch of the Mi Remote application
The main tool for managing the app is the Mi Remote (or Mi Remote) application, which is often already on the desktop or in the Tools folder in global versions of MIUI and HyperOS firmware. If you haven’t found the icon, it may have been removed or installed in your regional version of the software, in which case it can be downloaded through the GetApps store or the official Xiaomi website.
When you first start up, the system will ask for permission to access various functions of the phone. To properly operate the remote, you must provide permission to use geolocation (to determine the region and language) and, in some versions, access to storage to save device profiles. Without these permissions, the application may not work correctly or display a complete list of brands.
The interface is intuitive and divided into several tabs. At the top of the screen are usually switches between add modes, and in the center is a list of already configured remotes. Pressing the Add button (often marked with a plus) triggers a customizator that will guide you through all the stages of pairing. It is important to choose the right type of device from the proposed list: TV, Box, AC (air conditioner), Projector and others.
☑️ Checking before setting up
Step-by-step setting up the remote for the TV
Setting up your TV is the most common task. After choosing the type of TV device and the brand of your TV (for example, Samsung, LG, Sony), the system will offer to test the signal, and the phone will have a power button or volume control on the screen, which you need to press when watching the TV reaction.
If the TV responds to pressing (turns off, changes volume), you need to confirm this by selecting the "Yes" option. If there is no reaction, the application will prompt you to check the next code. The process can be repeated several times until a working protocol is found. In some cases, older TV models require manual code entry or use of Auto-match mode, which retrieves all available signals automatically.
Once tested successfully, the system will suggest giving the device a name (e.g., "Living room TV") for easy identification, especially if you have multiple remotes in the same app, and you can configure additional features such as voice search or macros to quickly launch applications if the TV supports Smart TV and is connected to the same Wi-Fi network.
| Type of device | Required module | Range of action | Features |
|---|---|---|---|
| Television | IR port/Wi-Fi | 10 meters | Direct visibility is required for the IR |
| Air conditioner | IR port | 8 meters | It is important to direct the receiver exactly. |
| TV Prefix | IR port / Bluetooth | 5 meters | Often requires conjugation |
| Projector | IR port | 7 meters | May require signal delay |
💡
If the TV doesn’t respond to any of the codes, try to choose a Generic or Outer brand and run a full automatic search of all known signals.
Setting up air conditioning and other household appliances
Controlling air conditioning via a smartphone is especially important in the summer, when the original remote can get lost or fail. The setup principle is similar to the TV: select the AC type, find the manufacturer and test the signals. But here is a caveat: the air conditioner must be on the network, but be in the off state (standby mode) in order to respond correctly to the on signal.
For other techniques, such as audio systems, DVD-And the key is that you have a line of sight between the phone and the receiver, and the infrared beam doesn't go through walls and furniture, so you have to keep the phone at a distance when you're setting up. 1-3 meters from the equipment, directing the upper end of the smartphone directly to the reception sensor.
⚠️ Warning: When setting up your air conditioner, make sure you are within range of the IR signal; if you step aside, testing may give a false negative result.
Some modern home appliances support hybrid control, which means that after initial configuration via an infrared port, the app can suggest switching to Wi-Fi control to expand functionality, allowing not only to turn the device on and off, but also to monitor its status, receive notifications and integrate the equipment into a single Mi Home ecosystem.
What to do if the brand is not on the list?
Using Wi-Fi Control for Smart TV
Owners of modern Smart TVs can use a more advanced method of control - through a local Wi-Fi network. This method does not require an infrared port in the phone and allows you to control the equipment even without direct visibility (for example, from around the corner or through one wall if the Wi-Fi signal passes).
When you add a device over Wi-Fi, Mi Remote automatically scans the network for compatible equipment. The pairing process may require confirmation on the TV screen (entering). PIN-This method provides two-way communication: you see the real state of the device (on or off) in the application interface, which is not possible with a conventional IR remote.
The advantage of Wi-Fi management is the ability to enter text from the keyboard of a smartphone, which is extremely convenient for searching for YouTube videos or entering passwords in applications. In addition, you can transfer files to the TV or broadcast the screen of a smartphone through the network. However, it is worth remembering that when communication with the router is cut off, control will disappear, while the IR port works autonomously.
💡
The combined approach (IC + Wi-Fi) gives maximum control: IR guarantees the device to be turned on, and Wi-Fi provides an advanced interface and text input.
Solution: If the remote is not working
Despite the ease of setting, users may face problems. One common cause is contamination of the IR emitter. Dust or a protective film covering the top end of the phone can block the signal. Wipe the top of the smartphone with a soft cloth and remove any protective accessories that may overlap the sensor.
Another common problem is that the application is not working properly because of energy saving. MIUI aggressively manages background processes and can "sleep" the remote application, which causes it to stop responding to presses. You need to go to the battery settings, find the Mi Remote application and set the Unlimited mode, and fix it in memory (lock in the menu of running applications).
If no code fits, your device may be using a non-standard protocol or frequency not supported by Xiaomi’s database, in which case you can try third-party apps from Google Play, such as ZaZa Remote or Anymote, which have their own codebases and matching algorithms. They often help where the standard solution is powerless.
⚠️ Warning: Third-party apps may request redundant permissions; use only proven high-ranking programs and read reviews carefully before installing.
