Modern Xiaomi and Redmi smartphones often come equipped with a built-in infrared port, which turns the device into a universal remote control. However, many users mistakenly believe that the app requires Mi Remote Controller A complex connection to the router's home network is required. In fact, the main functionality is based on a direct IR signal, but integration with Wi-Fi network Provides access to control smart TVs and Android TV set-top boxes.
Understanding the difference between infrared and wireless data transmission is critical to proper system operation. If your phone doesn't have an IR port, the app will automatically suggest using Wi-Fi to search for compatible devices on the local network. In this case, the smartphone and TV must be on the same subnet to ensure seamless command transmission.
In this article, we'll explore the technical nuances of setup, examine common connection errors, and explain how to get your universal remote working even in challenging network conditions. The key point is the presence of an IR port on the smartphone for working with classic equipment, while Wi-Fi is only necessary for Smart TVs and TV boxes.
Operating principles of the IR port and Wi-Fi module
The fundamental difference between the two control methods lies in the physics of the process. An infrared port (IR blaster) emits pulses of light that are invisible to the human eye but are detected by the TV's receiver. This method requires no network setup, pairing, or passwords. Simply point your phone at the device.
On the other hand, management through local network (Wi-Fi) uses TCP/IP protocols to transmit commands. This allows you to control devices even if they are in another room, provided both devices are connected to the same router. This approach is often used for Android TV Box or Smart TVs that do not have an IR receiver.
It is worth noting that the application Mi Remote Intelligently detects available interfaces. If you try to add a device that doesn't support IR control, the system will automatically offer to search for it over the network. However, for classic TVs, DVD players, and air conditioners, Wi-Fi is not used at all.
Sometimes users confuse the need to update the code database with a network connection. The app may request internet access to download new remote control profiles, but this is not the same as Wi-Fi control. The code database is updated periodically to ensure support for new appliance models.
Preparing your smartphone and checking compatibility
The first step before setup is to ensure your device is technically ready. Not all Xiaomi models are equipped with the necessary hardware. You can check for an IR port visually by looking at the top of your smartphone, or consult the specifications on the official website.
If you don't have an IR port, don't worry. You can still control your smart devices via Wi-Fi. In this case, make sure your smartphone and the target device (TV, set-top box) are connected to the same access point. Frequency differences 2.4 GHz And 5 GHz Usually it doesn't matter if the router is configured correctly to aggregate clients.
⚠️ Note: Some global versions of Xiaomi smartphones may have software limitations or missing drivers for the IR port, even if it's physically present. In such cases, flashing the device to the Chinese version of MIUI or installing third-party drivers may help.
You also need to check the application's permissions. When you first launch it Mi Remote The app will request permission to use geolocation and local network. Without Local Network permission on iOS or Android 10+, the app won't be able to find devices over Wi-Fi.
Step-by-step setup of Wi-Fi control
The process of adding a wirelessly controlled device differs from setting up an IR remote control. Here, we don't select signal encoding; instead, we search for the device on the local network. The steps are strictly defined by the app interface.
To get started, open the app and tap the add device icon (usually a plus sign in the corner or the "Add" button). Select the "TV" or "Box" category, then find your brand in the list of brands. If your brand isn't found, select "Generic" or "Android TV."
☑️ Connection Preparation Checklist
Next, follow the on-screen instructions. The system will attempt to find the device automatically. If the search fails, you may need to manually enter the IP address or activate pairing mode on the TV itself through its settings menu.
Settings → About TV → Assembly (7 times) → USB debugging (enable)After successful detection, the app will prompt you to test the buttons. This is a critical step, as different Android TV implementations may respond differently to standard commands. If the "OK" button works but the "Back" button doesn't, try changing the remote control profile in the device settings.
⚠️ Important: If your router separates your network into "Guest" and "Main" networks, make sure both devices are in the same zone. Guest networks are often isolated and block devices from discovering each other.
Setting up an IR remote control for classic equipment
For appliances without smart features, infrared radiation is used. Wi-Fi setup isn't required, but choosing the right model is important. In the app Mi Remote contains a huge code base covering tens of thousands of devices.
Select the device type (e.g., "Air Conditioner" or "TV"), then the brand. The app will prompt you to run a series of tests: "Is the sound working?" and "Has the volume changed?" Answer these questions honestly, as choosing the correct code depends on them. If none of the codes work, use the "Code Search" feature or enter them manually.
| Device type | The need for Wi-Fi | Range of action | Availability of feedback |
|---|---|---|---|
| Smart TV (Android/WebOS) | Yes (for full functionality) | Up to 15-20 meters | Yes |
| Regular LCD/LED TV | No (IR only) | Up to 8-10 meters | No |
| Air conditioner | No (IR only) | Up to 5-7 meters | No |
| TV Box (Mi Box) | Yes (Bluetooth/Wi-Fi) | Up to 10 meters | Yes |
It's important to understand that the IR signal requires a clear line of sight or good reflection from walls. If you put your phone in a case that covers the top, the signal may be blocked. Remove the case or use an external IR adapter that plugs into the port. 3.5 mm or USB-C.
Some complex devices, such as older receivers or projectors, may require remote learning. In this mode, you point the original remote at the phone and transmit button codes one by one. This allows you to clone the functionality of a lost remote.
What to do if the code base is empty?
If your brand isn't listed in the app, try selecting a universal profile or a generic (OEM) brand. Remote controls for different brands often have identical code tables. You can also try the "ZaZa Remote" app, which has a more extensive database and allows you to import codes into Mi Remote.
Solving common connection problems
Despite the simplicity of setup, users often encounter difficulties. The most common issue is "Device not found." This almost always indicates a network configuration error. Check if AP Isolation is enabled in your router settings.
Another common issue is command lag. If you press a button and the TV takes 2-3 seconds to respond, the Wi-Fi channel may be overloaded. Try switching devices to a less crowded frequency or changing the router's broadcast channel.
- 📡 Changing DNS: Sometimes it helps to enter static DNS (for example, 8.8.8.8) in the router settings or the TV itself.
- 🔄 Restarting the service: In the Android TV developer menu, you can find the "USB debugging" option - re-enabling it often resolves the visibility issue.
- 🛡️ Antiviruses: Third-party antivirus software on your router or network may block broadcast packets needed to locate devices.
If the IR port stopped working after a system update, check your power saving settings. The system may have limited background app activity or disabled the port to save battery. Mi Remote in exceptions.
Advanced capabilities and automation
Once successfully set up, the world of automation opens up. You can create scenarios where turning on the TV automatically turns off the lights in the room or closes smart curtains. To do this, Mi Remote integrates with the ecosystem Mi Home.
Using a voice assistant is also becoming available. By connecting to Google Assistant or Yandex Alice, you can control your devices with your voice, using your smartphone as an intermediary or an IR transmitter.
Advanced users can create macros. For example, a single "Movie" button can: turn on the TV, switch the input to HDMI 1, launch the YouTube app, and dim the screen. This requires careful adjustment of the time delays between commands.
⚠️ Note: App interfaces and menu item names may change with MIUI and HyperOS updates. If you don't find the feature described, use the search within your phone's settings or refer to the manufacturer's official support materials.
Can I use Mi Remote without internet?
Yes, you don't need an internet connection at all to control via IR. Wi-Fi control only requires an internet connection during the initial search and pairing process. After setup, commands are transmitted locally within your network.
Why doesn't the app detect my Samsung/LG TV?
Samsung and LG TVs use proprietary protocols. Make sure the "Remote Control" or "Mobile TV" feature is enabled on your TV. Also, try third-party apps if the default profile doesn't work.
Does Mi Remote work via Bluetooth?
The default app uses IR and Wi-Fi. However, some TV boxes (such as the Mi Box S) can connect via Bluetooth for voice transmission, but basic control is emulated via Wi-Fi Direct or a local network.
How do I add a button that isn't in the standard set?
In the remote control editing mode, you can add additional buttons from the extended list or use the "Learn" function if you have an original remote control with the required button.
