The situation when a smartphone with a pre-installed Mi Remote application refuses to detect a TV is familiar to many owners of the Xiaomi ecosystem. Users often face the fact that automatic search of devices on the local network does not bring results, or the phone’s IR port does not respond to commands, which causes natural irritation, because the universal remote is one of the key features of the MIUI and HyperOS shell.
The problem can be both the banal settings of the router and the hardware incompatibility of your smartphone’s infrared transmitter with the TV receiver. It is important to understand that modern Xiaomi TVs use two main communication channels: Wi-Fi for smart functions and an infrared port for basic control. If one channel does not work, this does not mean a complete system failure, but requires switching to an alternative method.
In this article, we will take a closer look at all possible causes of pairing failure, look at router settings, check application permissions, and address the technical details of IR ports, and get accurate diagnostics to help you regain full control of your multimedia system without having to buy a physical remote.
Problems with network connectivity and protocols
The most common reason an app doesn't see a TV is because of the network configuration. To work over Wi-Fi, both your smartphone and your TV must be on the same subnet. If your router is broadcasting at 2.4 GHz and 5 GHz with different network names (SSIDs), make sure the gadgets are connected to the same frequency. Smart Connect routers sometimes isolate devices from each other for security reasons.
It’s also worth checking the router’s API Isolation settings, which prevent devices connected to the same Wi-Fi network from sharing data with each other, and if it’s activated, the TV won’t be able to physically respond to a search request from the Mi Remote app.
Often, a simple restart of network equipment helps: pull the router power cord out of the socket for 10-15 seconds, then turn it back on and wait for all services to be fully loaded, and then reconnect the phone and TV to the network.
Remember that some antivirus programs or built-in firewalls on smartphones can block local traffic, and check if the Mi Remote app has a back-end or LAN restriction.
💡
For Mi Remote to work smoothly, both devices must be on the same subnet without customer isolation (AP Isolation).
IR port settings and frequency compatibility
If you use an infrared port to control, the problem may be that the frequency or angle of transmission is incompatible. Unlike Bluetooth or Wi-Fi, an infrared port requires a line of sight or a high-quality reflection of the signal from the walls. The infrared receiver on the TV must "see" the emitter of the phone.
Mi Remote uses a codebase that can contain errors for certain TV models. If automatic code selection fails, try manually selecting the model closest to yours. Sometimes codes from Redmi TVs work well with Mi TVs and vice versa.
⚠️ Warning: The IR port on the phone may be covered with a protective case or contaminated.Wash the top end of the smartphone with a soft cloth and remove the case to check the signal quality.
There's also the possibility that the IR emitter itself will fail, and check it by pointing the camera of another phone at the end of your smartphone and pressing any button in the remote app, and if you see a purple or white glow on the camera screen, the transmitter is working properly.

Application permissions and system limitations
Modern versions of Android (especially Android 10, 11, 12 and above) strictly control the access of applications to the local network and hardware modules. If the Mi Remote application is not granted the appropriate permissions, it simply will not be able to scan the network or use the IR port.
Go to your smartphone settings, select the Apps section, find Mi Remote (or Remote), and go to Permissions. Make sure Local Network, IR Port Device (if there is a separate item) and Geolocation are activated. The last item is often required by the system to run the Wi-Fi scanner.
- 📱 Local area network: allows the application to find devices in your Wi-Fi.
- 📡 Geolocation: necessary for the operation of the Wi-Fi module on Android.
- 🔋 Auto-Run: Allow the application to start automatically so it doesn’t fall asleep".
- 🔌 Background activity: Important to receive notifications about connection status.
In addition, the MIUI's aggressive energy-saving system can kill the remote process in the background, go to the battery settings, find the app, and set the "No Limits" mode, which will prevent sudden connection breakdowns.

Comparison of Connection Methods: Wi-Fi vs IR
Understanding the differences between the two main management methods will help diagnose the problem more quickly, each method has its own advantages, disadvantages and use cases. Below is a table to help determine which method is best used in your situation.
| Characteristics | Wi-Fi (Networked) | IR port (Infrared) |
|---|---|---|
| Direct visibility required | No. | Yes. |
| It works without the internet. | Yes (local area network) | Yes. |
| Additional functions | Voice input, keyboard | Just the remote buttons. |
| Router dependency | Tall. | Absent. |
If you only need basic functionality (on, off, volume), the IR port will be more reliable, because it does not depend on the settings of the router. However, to fully use the Smart TV, enter text through voice search and use the YouTube or Netflix application from your phone, you need to establish a connection via Wi-Fi.
In some cases, the TV may appear in the list of infrared devices but not respond to commands, which indicates that the model code is incorrect. Try the button test feature in the app to check the TV's response to different sets of codes.
💡
If the IR port doesn’t work, try using a Type-C to IR adapter that can be connected to the smartphone charging connector.
Failures in the operating system and application
Software errors are a common cause of instability. Mi Remote can accumulate cache, which over time leads to conflicts, and it is recommended to regularly clean the app cache through the memory management menu.
It’s also worth checking for updates to the app itself in the GetApps store or Google Play. Developers regularly release patches that fix compatibility bugs with new versions of Android and new TV models. An outdated version of the app may simply “not know” that your TV exists.
If the problem occurs after updating the TV firmware, try resetting the network settings on the TV itself. → Network and Internet, and select "Forget Network," then reconnect. IP-address and network protocols.
⚠️ Before resetting your network settings on your TV, make sure you know the password from your Wi-Fi, as it will have to be re-entered.
In rare cases, a complete reinstallation of the application helps: remove Mi Remote, restart your smartphone and download the application again, which ensures that all system files of the application are restored to their original, working state.
Hardware malfunctions and specific models
Not all Xiaomi smartphones are equipped with an IR port; budget models or versions for some regions may lose this module for the sake of saving space or cost. If your phone’s specifications do not mention InfraRed, controlling through an IR port is physically impossible.
There are also models of TVs that have a hidden or non-standard IR receiver. In some slim Mi TV Stick or Mi Box models, the receiver can be displayed on an extension, and make sure that you point the phone at the receiver, not at the logo or screen.
If none of these methods worked, the problem may be the TV's Wi-Fi module: If the TV is not connected to the network or permanently loses connection, the remote control over the Wi-Fi will not work, which requires diagnosing the TV's network card or using an external USB Wi-Fi adapter (if the model supports).
💡
The lack of an IR port in a smartphone makes it impossible to manage without the Internet, but network connectivity remains available.
