Owning a modern Smart TV from Xiaomi opens up a lot of multimedia options for the user, but sometimes the regular remote can get lost, discharge or simply fail at the most inopportune moment. It is in these situations that your smartphone comes to the rescue, which, thanks to built-in communication modules, can instantly turn into a full-fledged universal controller. This is not just a temporary solution, but also a way to get advanced functionality that is not available to the standard buttonbar.
Modern technology allows you to organize the interaction between the gadget and the screen in two main ways: through the infrared port (if you have it in the phone) or through the local Wi-Fi network. The first option emulates the operation of a conventional remote, sending light signals, the second uses a software protocol for data transfer, which allows you not only to switch channels, but also to enter text from the keyboard of the smartphone, manage files and even broadcast the image. It is important to understand what type of connection is available to your device to choose the best method of setting.
In this article, we’ll take a look at how your Android or iOS device can become a powerful home theater management tool, which apps are most reliable, how to set up syncs correctly, and what to do if devices don’t see each other. The key to Wi-Fi is to have both devices on the same router subnet, without guest networks or customer isolation.
Technical requirements and compatibility of devices
Before you start setting up, you need to make sure that your hardware is technically ready for interaction. For Xiaomi Mi TV and Redmi TV, remote control support is built into PatchWall or Android TV. However, the smartphone must meet certain criteria. If you plan to use an infrared port, having a transmitter in the phone is a requirement that is often found in Xiaomi, Redmi and Poco models, but rarely in other brands.
When using a wireless connection over Wi-Fi, the requirements are shifted to the software part. Both devices — and the phone and TV — must support DLNA standards or have pre-installed services Google Cast. Also worth considering the version of the operating system: for stable operation of modern applications remotes recommended Android 8.0 and higher or iOS 13 and later. Older versions of the software may not support the necessary encryption protocols.
⚠️ Attention: In the IR method, the TV and phone must be in line of sight. The infrared beam does not bend obstacles, so trying to switch the channel from around the corner or through a closed cabinet door will not be successful.
It’s also worth noting the power difference: a Wi-Fi module and a smartphone screen running continuously in remote mode can consume battery power faster than using a conventional IR transmitter. If you use your phone as a remote often, make sure you have access to charging or power saving mode enabled for background processes that are not related to control.
Official Mi Remote app: installation and configuration
The most reliable and functional tool for managing Xiaomi equipment is the Mi Remote app, which is designed with all the features of the manufacturer’s ecosystem in mind and ensures the best compatibility. For Xiaomi smartphone users, this application is often already built into the system, but owners of other Android devices and iPhones will need to download it from official Google Play stores or the App Store.
The installation process is simple, but it requires careful consideration when choosing the type of device. Once the program is launched, you need to click on the add button for a new device and select the category "TV". Then the system will suggest choosing a brand - in this case, it is Xiaomi or Mi. The application can automatically scan the network and find available TVs if they are connected to the same router, which greatly speeds up the pairing process.
If the automatic search didn't work, you can use manual mode, in which case virtual buttons will appear on the phone screen, and you will be asked to press one of them to check the reaction of the TV. This is the standard procedure for calibrating codes for the IR remote. For Wi-Fi connection, it is enough to confirm the request on the TV screen using the buttons on the TV itself or confirmation in the interface.
- 📱 Download the Mi Remote app from the official app store of your operating system.
- 📡 Make sure your smartphone and TV are connected to the same Wi-Fi network.
- 🔘 Select the type of device «TV» and the brand "Xiaomi" in the program interface.
- ✅ Confirm pairing by following the instructions on the screen, or test the buttons.
Once you have successfully set up, you can rename the remote for convenience, especially if you have multiple devices saved in the application, such as a TV in the living room and a projector in the bedroom. The app's functionality allows you not only to control playback, but also access the settings menu, run apps and use voice input.
☑️ Checking before connection
Alternative applications and third-party solutions
While Xiaomi’s official software is preferred, there are times when additional features are required or a standard app doesn’t work properly on a particular smartphone model, and third-party developers who have built powerful analogues come to the rescue, and one of the most popular solutions is Google’s Android TV Remote Control app, which is ideal for Android TVs.
Another strong player in the market is the TV Remote app - Universal Control, which is notable for supporting a huge number of brands and has very flexible interface settings. The user can place buttons on the screen, create macros to perform sequences of actions and even customize gesture control, which is especially true for advanced users who want to automate their use cases.
It is important to keep security in mind when installing third-party software. Apps that require suspicious permissions, such as accessing contacts or a microphone without an obvious need, are best avoided. Controlling a TV does not require deep access to a user's personal data. Always check the app's rating and other users' reviews before installing.
⚠️ Note: Some free remote applications may contain intrusive advertising that overlaps the control interface. Carefully study the terms of use and consider buying a Pro version for comfortable work without interruptions.
For iOS users, the Remote for Android TV app will be a great option. It provides a stable connection and supports keyboard function, which is extremely convenient for finding content on YouTube or Netflix. The interface of such applications is often adapted to the horizontal position of the smartphone, turning it into a full-fledged control panel with a touchpad.
Using an IR port against Wi-Fi: Comparison of methods
The choice between infrared and wireless depends on your specific needs and operating conditions. The infrared port provides versatility and independence from the TV's software. In fact, the phone becomes an exact replica of the physical remote, which means that you can turn off the TV even if the PatchWall system is getting stuck and does not respond to network commands.
Wi-Fi, in turn, provides a much broader range of capabilities. In addition to basic control, you get a full-fledged keyboard for text input, the ability to stream photos and videos from your smartphone to the big screen, and voice control. Response speeds on Wi-Fi connections are usually higher, and you don't have to aim your phone at the TV receiver.
Let’s look at the main differences in the form of a table for clarity:
| Characteristics | Infrared port (IR) | Wi-Fi connection |
|---|---|---|
| The need for direct visibility | I'll be sure. | Not required |
| Work without TV | Possible (on/off) | Active OS required |
| Keyboard function | Absent. | Full support |
| Phone battery consumption | Minimum | Medium/High |
| Additional functions | Just the remote buttons. | Broadcast, files, voice |
The ideal scenario is that both methods are available, in which case the IR port is used as an emergency option or for basic operations such as turning on and adjusting volume, and Wi-Fi is used to navigate menus and enter queries. Many modern remote applications automatically switch between these modes, choosing the most suitable one at the moment.
Secrets of the IR blaster
Advanced functions: keyboard, voice and broadcast
One of the most annoying things about using a Smart TV is typing text with buttons on the remote. Using a smartphone as a virtual keyboard solves this problem dramatically. Remote apps have a feature that automatically opens the input field on the phone screen whenever a text request appears on the TV, which allows you to type YouTube searches, logins and passwords for streaming services at the usual speed.
Voice control is another powerful feature available through a mobile app. A smartphone microphone often has better noise reduction quality than a TV's built-in microphone, especially if the remote is far away. You can dictate the commands "Find 90s comedy" or "Enable Netflix," and the phone will transmit that audio stream or text command to the TV for performance.
The Cast feature allows you to display the contents of the phone screen or individual media files on a large screen, which is especially convenient for viewing photos from the gallery or videos stored in the device’s memory. The remote application interface often has a separate Cast button that opens a list of available media files and allows you to send them to play.
💡
Use the Touchpad feature in the pod app to control the mouse cursor on your TV, which is especially convenient in the browser or when navigating in applications that are not adapted for the remote.
And don't forget the ability to control volume and multimedia. Unlike the IR remote, Wi-Fi allows you to see the playback status (pause, current time, track name) right on the smartphone screen, which allows you to quickly switch the composition or pause the video without breaking away from communication in messengers, if the application supports work in the background.
Solution: TV can't see remote
Despite the ease of setting up, users often face a problem when the phone and TV can’t find each other.The most common reason is using different Wi-Fi networks. Make sure both devices are connected to the main range (such as 2.4 GHz) rather than guest access, which often has customer isolation.
A second common problem is setting up a firewall or antivirus on a smartphone that can block local connections. Try temporarily disabling protection or adding a remote app to exceptions. Some routers also require the inclusion of UPnP or DLNA protocol to detect devices on the network.
If nothing works, try restarting the router. Often a temporary glitch in the table ARP-The router's addresses prevent devices from "seeing" each other. Simply turning off and on the router can solve the problem in a few minutes. Also make sure that the TV has the "Mobile Device Management" option on the network settings.
⚠️ Note: If you use a dual-band router with the same network names for 2.4 GHz and 5 GHz, try temporarily splitting them.Some older Xiaomi TV models may not work properly in automatic range switching mode.
In extreme cases, you can try static settings. IP-The problem is that both devices are on the LAN, although this is rarely necessary for home use, and most often the problem is simply desynchronizing the network stack, which is treated by rebooting both devices.
💡
90% of connection problems are solved by checking that the phone and TV are on the same subnet (the same number of connections). IP-router address, for example, 192.168.1.x).
