Modern Xiaomi and Redmi smartphones have features that completely eliminate traditional remote controls for home appliances. Built-in infrared port or Bluetooth connection support makes the device a universal controller for TVs, air conditioners, consoles and audio systems. However, many users face difficulties in the first run, not understanding why the application does not respond or how to activate signal transmission. Often the problem lies not in the breakdown, but in the lack of permissions or the correct settings of the system.
The activation process depends on your device’s specific model and the type of data technology you use. While older models rely solely on infrared, new flagships are increasingly using Bluetooth Low Energy to pair with smart technology. Understanding the differences between these protocols is key to successful customization. If you just upgraded your firmware or changed your phone, you’ll need to recalibrate and add devices to your database.
In this guide, we will take a detailed look at all the steps to turn on the remote, from checking the hardware to fine-tuning the Mi Remote software. You will learn how to bypass typical errors, why the proximity sensor may not work when controlling, and what hidden features are available in the engineering menu. The correct configuration will ensure that all your gadgets work smoothly through one interface.
Checking hardware compatibility and type of connection
The first step before you try to turn on the remote is to make sure that your Xiaomi or Redmi device is physically equipped with the necessary module. Not all smartphones support control of household appliances, and the lack of appropriate hardware makes installing third-party applications useless. Visually, the presence of an infrared port (IR-blaster) can be determined by looking at the upper end of the case: there must be a small black glass window.
If there is no characteristic blackout on the upper end, your device may be using Bluetooth technology to control smart appliances or not supporting remote control at all. In recent models, manufacturers sometimes abandon infrared ports in favor of more modern Wi-Fi Direct protocols or integration through the Mi Home ecosystem. Checking the specification on the official website or in the About Phone menu will help to dispel doubts.
- 🔍 Take a closer look at the top of your smartphone in bright light – the IR port looks like a small black dot.
- 📱 Check the device model in the settings: the presence of an IR port is often indicated in the characteristics on the manufacturer’s website.
- 📡 Make sure the Bluetooth module is on if you plan to control next-generation TV set-top boxes or sound panels.
- 🛠 Use another phone’s flashlight to illuminate the end – the IR port’s glass lens will be markedly different from the plastic body.
⚠️ Warning: Trying to use IR remote emulator apps on smartphones without a built-in transmitter will not work.
It is important to distinguish between types of connection, because the configuration method depends on it. Infrared port requires a line of sight between the phone and the receiver of equipment, whereas Bluetooth allows you to control devices even from another room if they are within range. For older TVs and air conditioners, only the infrared signal is relevant, while modern Smart TVs often support both protocols.
Configure the system application Mi Remote
The main tool for managing equipment in the shell MIUI and HyperOS is a pre-installed Mi Remote app (Mi Remote) if you uninstall it accidentally or it is missing from your regional firmware version (e.g. Global Remote). ROM Sometimes there is a lack of Chinese. ROM It is always there, you need to download it from the GetApps store or install it. APK-It's a file from a trusted source, and without that system component, you can't activate the remote.
Once the application is launched, the system will automatically request permissions, and it is critical to provide access to the camera (to scan codes), geolocation (to select devices by region), and, most importantly, permission to use the infrared port. Without these permissions, the application will run in limited mode or emit errors when trying to add a new device.
☑️ Preparation for Mi Remote
The interface allows you to create profiles for different rooms or types of equipment. You can add a TV, air conditioner, projector or console. When you first add the device, the customizer will suggest selecting a brand and testing the buttons. If the phone does not respond to presses during the test, check if the IR port is closed with a case or finger.
| Type of device | The port required | Whether a conjugation is required | Range of action |
|---|---|---|---|
| TV (old) | Infrared (IR) | No. | Up to 10 meters. |
| Smart TV (new) | Wi-Fi / Bluetooth | Yeah, (on the same network) | Up to 30 meters. |
| Air conditioner | Infrared (IR) | No. | Up to 8 meters. |
| TV Box (Mi Box) | Bluetooth | Yes. | Up to 10 meters. |
In some cases, manual signal frequency calibration may be required. If standard codes don't fit, the device profile settings can select the option "Manual Setup" or "Code Search" to start a brute force of all known signal combinations for the selected brand, which takes a few minutes, but is often the only way to "revive" a rare model of technology.
Activation of the IR port through the engineering menu
There is a scenario where the hardware is in good working order, the application is installed, but the remote is not turned on due to software lock or driver failure, in which case activation through the CIT (Customer Integration Test) engineering menu can help.
To enter the diagnostic menu, open the Phone app and dial the combination ##6484##. If the code is correct, the list of tests will open. Find the item associated with Infrared or IR. Clicking on this item will start testing the transmitter. If the test is successful, the system will confirm the module's operability, which often resets software errors of the driver.
What if the code doesn't work?
Inside the IR port test, you may be asked to point your phone to the receiver (or use another phone's camera to see an invisible glow) and press the check button. If the diode is flashing purple light (visible through the camera), then the hardware is fully functional. If there is no glow even in the test, you may need to flash the device or repair it.
- 📞 Enter the code ##6484## in the dialing app to enter the CIT.
- 🧪 Select Infrared from the list of available checks.
- 👁 Point the end of the phone to another smartphone’s camera to visualize the IR signal.
- ✅ Make sure the test is completed successfully (pass status) before entering the main menu.
Connection of Bluetooth devices and TV Box
Mi Box, Mi TV Stick and modern TVs are often controlled via Bluetooth instead of the IR. To enable this feature, you need to go to the standard Android settings. Open Settings → Bluetooth and make sure the switch is activated. The phone will start searching for available devices within range.
To interface with TV-Xiaomi often doesn't require manual search, but you just need to turn on the console and bring it an unlocked smartphone with Bluetooth enabled and an active Mi Account account. MIUI It automatically recognizes the next device and offers a quick pairing through a pop-up, which is the most convenient way to avoid the need to enter codes.
⚠️ Note: When pairing a Bluetooth remote, make sure that the console or TV is not connected to a physical remote that can intercept control and block the connection of the smartphone.
If automatic detection fails, use the Add Device feature inside the Mi Remote app. Select the TV Box or Console device type, then press Search. The process can take up to 30 seconds. Once successfully connected, you can use the smartphone screen as a touchpad and keyboard, which is much more convenient than standard buttons.
💡
For stable operation of the Bluetooth remote, keep the smartphone unlocked. In sleep mode, the connection can break to save energy.
Solving problems with performance and updates
A common cause of a broken remote is the permissions that fly off after an Android or MIUI update. New versions of the operating system can automatically disable applications from sensitive modules, such as an IR port, for security reasons.
Switch to Settings → Applications → All apps → Mi Remote → Access rights. Make sure all switches, especially Infrared Port and AutoStart, are activated. Autostart lock can prevent the remote from running if you try to call it through a sidebar or widget rather than opening the main application.
It's also worth checking for updates to the Mi Remote app itself. Developers regularly update code databases for new TV and air conditioning models. Go to GetApps or Google Play, find the app and click Update if a new version is available. The old codebase may not contain drivers for your appliance.
In rare cases, a third-party antivirus or memory cleaner may cause conflict. If the remote still doesn't turn on after checking the permissions, try adding the Mi Remote app to the battery exception list (Settings → Battery → Activity Control). Select "No Limits" mode so that the system doesn't "kill" the remote process in the background.
Alternative solutions and third-party applications
If the regular Mi Remote app doesn't work or support your rare model, you can turn to third-party solutions. The market offers many alternatives that use the same hardware IR port. Popular options are Sure Universal Remote, ZaZa Remote and Lean Remote. They often have more flexible frequency settings and the ability to manually train signals.
Emulator apps like AnyMote can also be a lifeline, with a huge codebase that is updated by the community, and they work in a way similar to the system solution: you pick a device, test buttons, and save a profile, but it's worth remembering that third-party apps can contain ads or require subscriptions for advanced features.
- 📲 ZaZa Remote is an excellent solution for air conditioning and complex audio-video equipment with the possibility of training.
- 🎛 Sure Universal – Supports macro creation (one button triggers several actions).
- 🌐 Google Home – If your TV supports Chromecast, you can control it without an infrared port at all via Wi-Fi.
- 🔧 Lean Remote – a minimalist application without unnecessary advertising, ideal for quick access.
⚠️ Note: When installing third-party applications from unknown sources (APK-Be careful. download software only from proven resources to avoid the introduction of malicious code.
The use of alternative software is especially relevant for older Xiaomi models that have stopped receiving system application updates. In such cases, a third-party developer can provide support for new protocols, extending the life of your gadget as a universal remote.
💡
If the regular app doesn’t see the device, try third-party software (ZaZa, Sure) – they often have more complete codebases for rare equipment.
