How to turn on and configure the remote on Xiaomi Redmi Note 7

Many Xiaomi smartphone owners face an underrated feature hidden right at the end of the case. The infrared port on the Redmi Note 7 makes it possible to turn your phone into a universal remote control for all household appliances in the house. It is not just a handy little thing, but a complete replacement for a dozen physical remotes that are forever lost between the pillows of the sofa.

Activating this feature does not require complex manipulation of the engineering menu or root rights. In the MIUI system, all the necessary drivers are already built in, and the user only has to run the pre-installed application or download its analogue. It is important to understand that the IR emitter does not need the Internet to work, unlike controlling through Wi-Fi, which makes the method reliable even in case of network failures.

In this guide, we will go into detail about the process of setting up, calibrating signals and solving typical problems. The infrared port on the Redmi Note 7 is located on the top end of the device, next to the noise reduction microphone. Make sure that this area is not covered with a case with high sides before you start setting up.

Technical features of the IR port on Redmi Note 7

The Redmi Note 7 is equipped with a full-fledged infrared transmitter that operates across a wide range of frequencies, allowing it to emulate the signals of thousands of models of TVs, air conditioners, consoles and audio systems. Unlike Bluetooth or Wi-Fi, infrared communication requires a line of sight between the phone's transmitter and the receiver of equipment, since IR rays do not bend obstacles.

The radiation power in Xiaomi is sufficient for confident reception of the signal at a distance of 7-10 meters. However, it is worth considering that bright sunlight can cause interference, since it also contains infrared spectrum. For stable operation in the daytime, try to keep the phone closer to the receiver or create artificial dimming in the transmission zone.

⚠️ Warning: Infrared port is an optical device. Do not glue the top end of the phone with opaque stickers or metallized cover elements, otherwise signal transmission will become impossible.

The software is implemented through the standard Android interface, where the application acts as a code generator. The frequency of signal modulation is automatically selected by the system depending on the type of device selected. The user does not need to manually adjust the hertzel, Mi Remote algorithms do this automatically when choosing a brand.

Installation and launch of the Mi Remote application

To control the equipment, the MIUI shell is pre-installed with the Mi Remote system application (in some regions it may be called the Mi Remote), and if you don't find it on the desktop, it may have been hidden in the Tools folder or removed during system cleanup, in which case it needs to be downloaded from the GetApps store or Google Play.

Once installed, run the application. When you first start, the system will ask permission to use the infrared port. You must agree to this requirement, otherwise the program will not gain access to the hardware module data, without this permission, all configuration attempts will end in error.

The interface is minimal and contains a button to add a new device. Click on the plus in the corner of the screen to begin the pairing process. The system will suggest you to choose a category of equipment: TV, air conditioner, projector, receiver or IPTV-Choosing the right category is critical, because it depends on the set of codes available for testing.

Step-by-step setting up the universal remote

The process of setting up is to consistently select the right code from the database. After selecting a category and a brand of equipment (for example, Samsung or LG), a test button will appear on the screen, usually "On / Off", you need to point the top of the phone to the device and click on the screen.

If the machine reacts (turns off or changes volume), press Yes. If there is no reaction, press No, and the system will suggest the following code, which can take anywhere from 10 seconds to a couple of minutes, depending on the rarity of your model and the quality of the IR receiver.

After a successful test, the system will ask you to name a remote, for example, "Living room TV" or "Bedroom Air Conditioning," which makes navigation easier if you add multiple devices, and you can also assign a remote control icon for quick visualization in the general list.

Solving problems with signal transmission

Sometimes the code seems to be matched, but the remote is unstable: it works every once or only from close range. First of all, check if the IR port on the end of the phone is contaminated. Dust and pile from your pocket can shield the radiation. Carefully wipe the end with a soft cloth.

The second common problem is code conflict: some universal codes can partially overlap the functions of other devices. If the TV remote suddenly starts to turn off the receiver, try changing the selected code to an alternative one in the Mi Remote app settings, even if the previous one worked fine, often solving the problem of crosstalk.

⚠️ Warning: If the phone is in a thick silicone or metal case, the range of the remote can be reduced to 1-2 Take off the case to check the performance.

Also worth checking is the power saving settings. In rare cases, MIUI Optimization can restrict the background operation of the IR module to save charge. Make sure that the Mi Remote application has a "No Limits" mode in the battery settings, which guarantees instantaneous response when you press the buttons.

Use of third-party applications and codes

If Xiaomi’s regular app doesn’t find your hardware or your codebase seems outdated, you can use alternatives from Google Play. Popular options like ZaZa Remote or Anymote often have more extensive codebases for specific or old hardware, and the way they work is similar: brand selection and code savvy.

Some advanced users prefer to manually enter HEX-Infrared signal codes found on specialized forums, and for this purpose, third-party applications have a "Add Manual" mode, which requires knowing the exact IR model of your equipment and the encoding format (NEC, RC5, Sony, etc.).

When using third-party software, it is important to give the necessary permissions. Android 10 and higher (relevant for updates to the Redmi Note 7) requires explicit permission to use the IR transmitter, without which the application will show hardware error, even if the port is physically healthy.

Expanded opportunities and use cases

The remote doesn't just turn on, you can set up macros in the Mi Remote app, for example, one button can turn on the TV in sequence, switch it to the TV. HDMI-Enter and run a media player, and this creates a smart home effect without having to buy expensive hubs.

Voice control is also available through Google Assistant, and when you set up the remote, you can say, "OK, Google, turn on the TV," and the phone will send the corresponding IR signal. To do this, you need to add a TV device in the Google Assistant settings and associate it with the remote.

💡

Save screenshots of successful remote codes in the cloud. If you reset your phone to factory settings, the code database in the app may clear up, and you'll have to reconfigure the remote.

For fans of Xiaomi and Mi Home, there is an opportunity to integrate IR remotes into a single ecosystem if you use intermediate gateways, but for the Redmi Note 7 itself, direct control through IR remains the fastest and most autonomous way.
