Mi Remote Xiaomi: what it is and how to turn your phone into a universal remote

(see above)

The modern smartphone has long since ceased to be just a means of communication, becoming a universal center for managing digital life. Owners of devices from the Xiaomi brand often wonder: Mi Remote Xiaomi what it is and why this system component is needed? The answer lies in the hardware feature of many of its phones – the presence of an integrated infrared port (IR Blaster).

In fact, Mi Remote is a hardware and software package that emulates signals from normal IR remotes, but with advanced functionality. Unlike the classic remote, which simply transmits the code of the button you press, the application on your smartphone can remember settings, create scripts and even be controlled by voice through Google Assistant or Alice, which makes it not just convenient to control appliances in the home, but truly intelligent.

In this article, we will discuss the principle of this technology, look at compatibility with various brands of equipment and answer the most common questions of users. You will learn why your phone may not see the remote, how to set up air conditioning control and what to do if your TV model is not in the database. Infrared port is not in all Xiaomi models, so before setting up be sure to check the specifications of your device.

The principle of the IR emitter in smartphones

The technology behind Mi Remote has been around for decades, but in smartphones, it has been given a second life by the power of modern processors. At the top of the device, there is a miniature IR LED that emits light pulses in a spectrum invisible to the human eye, and these pulses are modulated in a certain way, creating code sequences that household electronics receivers can understand.

Mi Remote acts as a database and signal generator. When you select a TV brand (such as Samsung or LG) from the menu and press a button on the screen, the phone's processor forms the corresponding binary code. This code is converted into an electrical signal that causes the IR LED to flash at a high frequency. The receiver on the TV picks up these flashes, decodes them and executes a command.

The main advantage of the smartphone over the conventional remote is the versatility and ability to update. the code base in the application is constantly updated by developers, which allows you to manage even very old or, conversely, the newest technology. In addition, the phone can store hundreds of profiles, making it an ideal solution for hotels, conference rooms or just a large apartment with many devices from different manufacturers.

⚠️ Attention: Infrared signal only works within line of sight. If there is a vase between the phone and the appliances or you have hidden the phone in your pocket, the command will not be executed.

It's important to understand that IR is one-way. The phone fires signals, but it doesn't get confirmation that the command is accepted, which is why, after every test action (turning on, changing the volume), the system asks you, "Is the TV working?" This is necessary to calibrate and select the right code from the many available for one brand.

Device compatibility and supported brands

One of the key questions for users is whether their equipment is compatible with the Mi Remote app. Fortunately, the application database covers the vast majority of electronics manufacturers in the global market. The system supports the management of not only televisions, but also consoles, projectors, air conditioners and even some models of audio systems.

When you first set up, you'll be asked to choose the device type and the manufacturer. The code search algorithm works sequentially, checking the most popular signal combinations. If the automatic search didn't work, you can always use manual mode or code search, if known.

Below is a table of the main categories of devices and brands that Mi Remote works with:

It's worth noting that support for specific models may vary, like older TVs. LG buttoned «OK» In the center of the remote, you may need to calibrate separately, and some specific functions, such as: 3D-The mode or smart features of specific brands may not be available if their code is not entered in the application database.

If your manufacturer is not on the list, don't be too upset. Often, devices of little-known Chinese brands use standard codes from large companies. OEM-In this case, it makes sense to try to go through the codes from the brands Haier, Hisense or TCL — The probability of coincidence is very high.

Step-by-step instructions for setting up the remote

The Mi Remote setup process is as simple as possible and takes only a few minutes. First, make sure that your smartphone has an IR port (it looks like a small black glass on the upper end) and has the Mi Remote app installed on it (or Mi Remote in Russian localization).

Launch the app and click Add Device (usually the + icon in the corner of the screen). The system will prompt you to select a category of equipment. After selecting a category (such as TV), a list of brands will appear. Find your manufacturer's logo and click on it.

Then the testing process will begin. A virtual button will appear on the phone screen (usually "On/Off"). Point the top edge of the smartphone to the device receiver and press the button. The app will ask, "Is the TV working?" If the device reacts (turned off or turned on), say "Yes." If there is no reaction, select "No" and the system will suggest the next code.

After a successful turn on test, you will be asked to check other features: volume, channel switching, menus. This is an important step, since some codes may turn on the TV, but do not adjust the sound. After all the steps, give the new remote control a name (for example, "TV in the living room") for ease of use in the future.

⚠️ Warning: Keep your phone still 5-10 cm from the receiver during setup, hand tremors or too much distance can lead to misidentification of the code.

If automatic code brute force didn't work, use Search, which is a mode where the app will change codes quickly while you're holding your finger on the screen. Once the device responds, let go of your finger. This method is often more effective for older techniques that don't have a clear code branding.

Control of air conditioning and complex equipment

The air conditioner is particularly important to tune, as its interfaces are much more complex than those of TVs. Unlike TV, where channel and volume are important, air conditioning is critical to temperature and operating mode. Mi Remote app can display the current temperature on the phone screen, synchronizing it with the state of the real device (visually).

When you add air conditioning, the system can suggest calibrating the mode buttons (Cool, Heat, Fan, Auto), which is necessary because the logic of switching modes is different from different brands (Ballu, Electrolux, Haier), where the Mode button cyclically changes modes, and somewhere for each mode there is a separate button.

An important feature is the ability to create shortcuts on your desktop, so you can put the 22-degree "Air Conditioner" button directly on your lock screen or widget, which eliminates the need to open the app and search for the right remote control every time it gets hot.

For complex applications like projectors or audio receivers, the app provides an extended menu, and you can configure macros, which are command sequences, for example, a single button called "Cinema" can turn on the TV at the same time, switch it to the desired one. HDMI-However, such scenarios often require an IR gateway (e.g., Xiaomi Gateway) because the phone must send commands sequentially while the screen is on.

Using Mi Remote in the Smart Home Ecosystem

Integrating the IR remote into Xiaomi’s Smart Home ecosystem opens up possibilities for automation. Although the phone itself is a mobile device, it can be linked to other gadgets through scenarios in the Mi Home app (if the phone acts as a controller) or use IR gateways for remote control.

Imagine a scenario where you leave your house, and the phone geolocates you to the point where you've left a 100-meter radius, and automatically switches off the TV and air conditioner, even if you forgot to do it manually, or vice versa, 15 minutes before you arrive, the system turns on the air conditioner to keep the apartment at a comfortable temperature.

Voice control is another powerful feature. By connecting your Mi Home account to Google Home or Yandex.Alice, you can command the voice technique, "Alice, turn on the TV." A smartphone or smart speaker with an infrared port will transmit a signal to the device, which is especially convenient for people with disabilities or when the remote is physically lost under the couch.

💡

Use Mi Remote widgets on your Android desktop to quickly access frequently used buttons without opening the full app. This saves time and battery life.

The phone itself can only control the equipment directly, being in the same room.

Troubleshooting and troubleshooting

Despite the reliability of the system, users can face problems, and the most common is that the phone can't see the devices or the codes don't fit. First of all, check if the IR port is covered with a case. Dense silicone or metal bumpers with high sides can block the beam.

The second common problem is calibration discharge after the system update. If the remotes are gone or stopped working correctly, try removing the profile of the device and re-create it. The codebase may have been updated, and the old profile may have become irrelevant.

⚠️ Warning: Don't use third-party IR port apps from unknown developers. They may request redundant permissions and contain ads. The built-in Mi Remote app is optimized for Xiaomi's hardware and is more stable.

If the IR port stopped working completely (the LED does not flash, which can be checked through the camera of another phone), the sensor itself or the plume may be damaged, in this case, software methods will not help, and you will need to contact a service center to replace the module.

💡

In 90% of cases, the problem with the remote is solved by recalibrating the code or removing the protective cover covering the IR port.

Also worth mentioning is the effect of bright sunlight: the sun's infrared radiation can jam the remote signal, making it impossible to control in a brightly lit room, in which case it helps to approach the receiver of the device at a minimum distance.
