The situation when a standard remote control from Android TV a set-top box breaks, gets lost or simply stops responding to presses is familiar to many users. At such moments, the TV screen turns into useless black glass, and access to your favorite movies and applications is blocked. Fortunately, modern technologies can quickly solve this problem using a device that is always at hand - your smartphone.
Turning a phone into a full-fledged remote control opens up not only the possibility of emergency control recovery, but also provides a number of advanced functions that are not available to conventional infrared remote controls. You get a virtual keyboard for quickly entering passwords, voice control through your smartphone's microphone, and even a touchpad function for more precise menu navigation. Let's consider in detail how to set up this interaction and what tools are required for this.
Network preparation and basic requirements
The foundation for a successful connection between a smartphone and a set-top box is the correct configuration of the local network. Both devices, the phone and TV boxmust be connected to the same Wi-Fi access point. This is critical because the communication protocols used by remote applications operate exclusively within the same subnet. If your router distributes networks at 2.4 GHz and 5 GHz frequencies with different names, make sure that the gadgets are connected to the same SSID.
In some cases, especially when using complex corporate networks or guest modes of routers, direct communication between devices may be blocked by security settings. You need to check that the Client Isolation feature is disabled in your router settings. Without this, even if there is a shared Internet, the devices will not “see” each other on the local network.
It is also worth paying attention to IP addresses. For stable operation, it is advisable that your set-top box receives a permanent IP address from the router, or you know its current value for manual entry in the application. Dynamically changing the address after rebooting the router may lead to loss of connection, and the setup procedure will have to be repeated again.
⚠️ Attention: If you are using a mobile hotspot (distributing the Internet from your phone), make sure that the set-top box itself supports connection to this type of network. Some older models Android TV may not work correctly with frequencies or encryption protocols used by smartphones in modem mode.
☑️ Check the network before connecting
Official applications from Google and manufacturers
The most reliable and simplest way to manage is to use certified software. Google has developed a special application Google TV (formerly known as Android TV Remote Control), which provides deep integration with the operating system of the set-top box. For it to work, Google Play Services must be activated on the TV and logged in to your account.
The pairing process in the official application is as automated as possible. After launching the app on your smartphone, it scans the network and displays available devices. All you have to do is select your set-top box from the list and confirm the appearance of a special code on the TV screen. This method guarantees support for all functions, including voice input and media player control.
However, if you have a set-top box from a specific Chinese brand, for example Xiaomi Mi Box or Beelink, it is also worth checking the proprietary utilities. Manufacturers often include proprietary protocols in their devices that work better with their native apps than with Google's standard solutions. In such cases, the official application from the brand may offer additional functions, such as screen casting or file management.

- 🔍 Mi Remote: A specialized application for the Xiaomi ecosystem, which also works via IR.
- 🎮 Vendor Specific Apps: Applications from manufacturers like Nvidia or Amazon Fire TV for advanced control.
If the official application does not find the set-top box, try to forcefully stop the Google Play Services on the TV through the developer menu and start it again - this often solves the problem of visibility on the network.
Third-party universal remotes
When standard methods do not work or the interface of the official application seems inconvenient, third-party developments come to the rescue. The store Google Play offers dozens of alternatives, which often have more flexible settings and support devices without Google certification. The leaders in this niche are applications like CetusPlay, Send Files to TV (which also has remote control functions) and TV Remote Control.
The main advantage of such apps is their ability to work with a wide range of devices, including budget Chinese boxes on pure Android that do not have a full-fledged TV shell. They often emulate keystrokes at the system level, which allows you to control even those menus that do not respond to standard commands.
Some advanced users prefer to use open source applications such as KDE Connect. Although this project was originally created to integrate a PC and a smartphone, its functionality fits perfectly into the task of managing media centers. You get not just a remote control, but a full-fledged clipboard exchange, file transfer and notifications between devices.
| Application name | Connection type | Voice input support | Setting complexity |
|---|---|---|---|
| Google TV | Wi-Fi / Bluetooth | Yes | Low |
| CetusPlay | Wi-Fi | Partly | Average |
| KDE Connect | Wi-Fi | No | High |
| Yatse | Wi-Fi / ADB | Yes (plugins) | Average |
Advanced control via ADB
For those who want to gain full control over their system, there is a method of connecting through the debug bridge ADB (Android Debug Bridge). This method requires prior activation of the developer mode on the console itself. Go to Settings → About device → Build number and click on this item 7 times until a message appears saying that you have become a developer.
After activating the mode, a new section “For Developers” will appear in the settings menu. In it you need to find the “USB Debugging” item (or “Network Debugging” in new versions of Android TV 11+) and switch it to the active state. This will open port 5555 for external connections, allowing system commands to be sent directly.
Using ADB client applications for a smartphone such as ADB Connect or Termux, you can not only emulate button presses, but also install applications, remove system software and change hidden system parameters. The command for emulating pressing the “Home” button is as follows:
adb shell input keyevent 3This approach is indispensable if the set-top box interface is frozen so badly that a regular remote application cannot send a command. The ADB protocol operates at a lower level and is often able to “reach” the system even in critical situations.
⚠️ Attention: Be extremely careful when using ADB commands. Incorrect entry of commands, especially those related to removing packages (
pm uninstall), can lead to system inoperability and the need for a complete flashing of the device.

Using the IR port smartphone
If your Wi-Fi network is unstable or the set-top box is not connected to the Internet, the only option is to use the infrared port. Many smartphones, especially models from Xiaomi, Huawei and Honor, are still equipped with a built-in IR transmitter. This turns the phone into a universal remote control that does not require any network setup.
To work, you will need an application like Peel Smart Remote or the built-in utility “Mi Remote”. The database of such apps contains codes for thousands of equipment models. You will need to choose the manufacturer of your set-top box and test several proposed button configurations until the TV begins to respond to presses.
The main disadvantage of this method is the need for line of sight. Unlike Wi-Fi, the infrared signal does not bend around obstacles or pass through walls. You will have to point the top of the smartphone directly at the receiver of the set-top box, which is not always convenient if the device is hidden behind the TV.
The IR port is the only solution that works completely autonomously, without depending on the router, drivers and network settings, which makes it an ideal emergency tool.
Solving problems with connection and visibility
Even after following all the instructions, users often encounter the fact that applications do not see the set-top box. One common cause is a firewall at the router level or antivirus software on a smartphone that blocks local connections. Try temporarily disabling protection or adding the application to the exclusion list.
Another common problem is “putting to sleep” the Wi-Fi module on the set-top box itself to save energy. In the TV's energy saving settings, find the item that controls the network in standby mode and turn it off. If the Wi-Fi module turns off when the screen goes dark, the phone will physically not be able to establish a connection.
In cases where all else fails, try static binding. Find out the IP address of the set-top box (in the “About the device” → “Status” section) and enter it manually in the remote control application, if such a function is provided. Often, automatic search (Broadcast) does not work due to routing features, and direct access to the address solves the problem instantly.
Why does the application write “Device not found” even though Wi-Fi is working?
Most often the problem lies in the router settings, where AP Isolation is enabled. In this mode, devices connected to Wi-Fi can access the Internet, but cannot see each other within the local network. Disable this function in the admin panel of the router.
Is it possible to control the set-top box if it is frozen on the splash screen?
If the system is completely frozen at the kernel level, Wi-Fi software remotes will not help, since the network stack does not process requests. In this case, only the infrared port (if it emulates a hardware shutdown) or a physical reconnection of the power will save you. However, if only the interface (launcher) is frozen, ADB commands can reboot the shell.
Does control via Bluetooth work without Wi-Fi?
The official Google TV app uses a combination of Wi-Fi for data transfer and Bluetooth for initial pairing and voice input. Full control without Wi-Fi is impossible, since the bandwidth and Bluetooth protocols are not enough to transmit the video stream of settings and complex interface commands.
How to enter the Wi-Fi password on a set-top box without a remote control?
Use the Google TV application on your smartphone. After connecting in remote control mode, click on the keyboard icon. Whatever you type on your phone screen will automatically appear in the input field on your TV. This is the fastest way to set up a network in the absence of a physical remote control.
