Xiaomi and RedmiMIUI, which allows you to replace physical remotes from TVs, air conditioners and consoles, but many users do not know that the infrared port is not always activated automatically when you first start the device.
The process of turning on depends on the model of your gadget and the version of the operating system installed. In some cases, you just need to start the application, and in others you need to activate the IR emitter through hidden settings. It is important to understand that not all phones have an infrared module, so before you start setting up, you should make sure that the appropriate equipment is on the upper edge of the case.
In this article, we will take a closer look at all the steps of activating, configuring codes, and solving common problems that users face, and learn how to turn your smartphone into a powerful home electronics management tool.
Check the presence of an infrared port on the device
The first step before you try to turn on the remote is to physically check the device. The infrared port (IR Blaster) looks like a small black window, usually located on the top of the smartphone next to the noise reduction microphone. If there is no such element on the top edge, it may not be provided with this feature in your model.
Modern flagship models Xiaomi often lose this module to save internal space, while budget and medium-sized models of the Redmi Note series are most often equipped with a full-fledged IR emitter. You can also check the presence of the module through the specifications on the official website or in the AIDA64 application, which displays a list of all sensors and components of the system.
If the physical port is present but the remote is not working, the problem may be software or contamination.Wash the top face with dry cloth, as fat or dust can block the signal.Also make sure that the device does not have third-party shells that block access to system functions.
Activation of the Mi Remote (Mi Remote) application
The main tool for managing the equipment is the Mi Remote app (or Mi Remote in Russian). To run it, find the corresponding icon in the application menu. If you can't find the program, search the system by typing the word "Remote" or "Remote" into the search bar.
When you first start up, the system will ask for permission to use geolocation and Bluetooth, which is necessary to determine your location and select the current codes for household appliances in your area, permissions are mandatory for the correct operation of the remote database.
Once you have accepted the user agreement, you will see a main screen that suggests adding a new device, click the Add Remote button or the Plus icon, and the system will suggest you choose the type of equipment: TV, air conditioner, projector, console or other equipment, and select the desired option to proceed to the next stage of setting.
Step-by-step setting up the universal remote
The process of setting up is to find the right digital code for your model of equipment. After choosing the type of device (for example, a TV) and the brand (for example, Samsung), a series of test buttons will appear on the phone screen. You need to point the phone at the equipment and press the power button.
If the device is turned off or has changed settings, say "Yes." If there is no response, press "No" and the system will suggest another code, a process that can take a few minutes, since the database contains thousands of combinations for different years of technology.
☑️ Checklist of successful setup
Once you've successfully selected the code, save the remote by giving it a clear name, like "Living room TV" or "Bedroom Air Conditioner," which will allow you to quickly switch between devices in the future. Now your smartphone is fully ready to work as a universal remote.
Use of IR emitter for control of equipment
The main advantage of using a smartphone instead of a regular remote is its versatility and additional features. You can control multiple devices at once, create scripts and even use the phone as a touchpad to input text on a Smart TV. To control, just open the application and select the desired remote.
Click on the on button to activate the technique. The Mi Remote application interface simulates a real remote, giving access to volume, channel switching and settings menu. Infrared signal is transmitted instantly, there is almost no latency if there are no obstacles between the phone and the receiver.
💡
Use the "Copy remote" feature if you have an old IR remote but don't know the TV model - the phone can read the signal from the old device.
It's worth noting that an IR port doesn't require an Internet connection after the initial code setup. However, if you're using Wi-Fi control (for Smart TVs), the phone and TV must be on the same network. In IR mode, the phone acts as a transmitter similar to a conventional remote.
Comparison of IR and Wi-Fi management
Xiaomi owners often confuse two types of control: through an infrared port and through a Wi-Fi network. Understanding the difference is critical for proper configuration. The IR port operates on the principle of line of sight and does not require network configuration, while Wi-Fi management allows you to control equipment from anywhere in the world where there is Internet.
Below is a table comparing the key characteristics of both methods:
| Characteristics | Infrared port (IR) | Wi-Fi / Bluetooth |
|---|---|---|
| Radio of action | Up to 10 metres (direct visibility) | Up to 30 metres (through walls) |
| Necessity of the network | Not required | Router required |
| Compatibility | Old and new techniques | Only smart devices |
| Energy consumption | Minimum | High. |
For air conditioners and older TVs, IR port is a non-allert option. For modern Smart TVs and Mi Box media consoles, it is more convenient to use Wi-Fi, as this opens up access to voice input and screen broadcast.
Troubleshooting and troubleshooting
Sometimes users are faced with a situation when the application is running, but the equipment does not respond. First of all, check whether the IR port is closed with a protective case or a bumper. Thick silicone or metal can completely block the signal. Remove the case and try again.
⚠️ Warning: If the IR port is closed with a dense material, the signal may be reflected inside the housing and damage the light sensor or proximity sensor.
The second common problem is the malfunction of the Mi Remote app itself. Try clearing the app's cache through the Settings menu → Apps → All Apps → Mi Remote → Clear the cache. If that doesn't work, delete the app's updates and install the current version from the GetApps store or Google Play.
What if my brand is not on the list?
Also make sure that the date and time settings are set to automatic mode. Some code protocols are time-tamped, and desynchronization of the clock can lead to signal errors.
Additional opportunities and use cases
Xiaomi's remote doesn't just have to switch channels. You can create macros, sequences of actions that can be done at a single click. For example, the Kino command can turn on the TV at the same time, switch it to the TV. HDMI-Enter the console and turn the light in the smart lamp.
For advanced users, integration with the Mi Home platform is available. By adding an IR remote to the smart home ecosystem, you can control voice technology through Google Assistant or Yandex Alice if they are connected to your Mi Account.
💡
Integration with a smart home turns a conventional IR remote into part of an automated system, allowing you to control the “stupid” technique with voice and scripts.
Use desktop widgets to quickly access frequently used features, and you can put the TV switch on or the air conditioner temperature adjustment directly onto the home screen without opening the app every time.
