How to control a Xiaomi projector without a remote: the complete guide

The situation of a remote from a smart device being lost, sat down or simply stopped responding at the most inopportune moment is familiar to many owners of modern technology. For Xiaomi projectors, which are often used for home theater or presentations, the lack of remote control can be a serious problem, since physical buttons on the case are often absent or hidden. However, it is early to panic: the Android TV ecosystem, on which most Mijia and Xiaomi Laser Projector models are based, provides several alternative ways of navigation.

In this article, we will take a look at all the possible ways to regain control of a device using only a smartphone, computer peripheral or connected appliance. You will learn how to activate debugging mode, which applications best emulate the original remote, and how to use HDMI-CEC to control via a TV or receiver. Even if the battery is dead, you can start a movie or change the brightness settings.

The challenge is that the projector interface is not always customized to control the mouse, and some features can be hidden in the depths of the menu. We'll look at both Google's standard solutions and specialized utilities that will turn your phone into a full-fledged voice-enabled remote. It's important to understand that some methods require pre-tuning, so check them out beforehand.

Using a Smartphone as a Universal Remote

The most affordable and functional way to control is to turn a smartphone into a remote control. Because Xiaomi projectors are based on Android, they support standard Bluetooth and Wi-Fi protocols, which allows you to use the mobile device as a full-fledged controller.

The first step is to install a dedicated app. The official Google Home app is often pre-installed on Android smartphones and allows basic management, but for advanced functionality, it is better to use specialized solutions. One of the most popular is Projector Remote Control or universal remotes like Mi Remote (if the phone has an infrared port), but for network models, applications that work over Wi-Fi are more effective.

⚠️ Warning: Make sure your smartphone and projector are connected to the same Wi-Fi network (the same as your Wi-Fi). SSID). If the phone is working via mobile internet (4G/5G), a projector via Wi-Fi router, the connection will not be established.

The pairing process usually takes no more than a minute. Once the application is launched, the smartphone screen will start searching for available devices on the local network. Once you see the name of your projector (for example, Xiaomi Laser Projector 1S), click on it. The projector screen may have a request for permission to connect, which you need to confirm. If the screen is not visible, try the blind input method described below.

• 📱 Android TV Remote Control – Google’s official app that works perfectly with Android TV, Supporting voice input and keyboard.
• 🎮 Projector Remote is a third-party application with button emulation specifically for projectors, including focus and zoom buttons.
• 🌐 Mi Home – If the projector is integrated into the smart home ecosystem, the basic functions (include, source selection) are available through the main hub.
• 🔌 IR blasters – Peel Remote apps only work if your smartphone has a built-in infrared port.

Using a smartphone offers the advantage of a virtual keyboard, which is critical for typing Wi-Fi passwords or finding content on YouTube. Text input from the projector's on-screen keyboard is extremely inconvenient, whereas from the phone you type a request in seconds. In addition, many applications allow you to stream an image or video directly from your smartphone to the projector, bypassing complex menus.

Connection USB-mouse and keyboard

If wireless methods are not available or the network is unstable, the most reliable hardware solution is to connect a conventional computer peripheral. Virtually all modern Xiaomi projector models are equipped with a single port. USB 2.0 or USB 3.0 that supports HID-This means that the system recognizes the mouse and keyboard immediately after you connect, without requiring driver installation.

To implement this method, you will need a standard wired or wireless mouse with a USB-Wireless mouse kits. + keyboard USB-And they do the most efficient job of using a dongle, taking up only one port, and when you connect, the cursor will appear on the projector screen, allowing you to navigate the tiles of the Android interface. TV. The left mouse button performs the function of “OK” or “Enter”, and the right button often emulates the “Back” button".

Keyboards are particularly useful for navigation, with arrow keys replacing the direction buttons on the remote, and Enter keys confirming the choice. In some cases, keyboard combinations can perform specific functions: for example, Alt + Tab can switch running applications if the projector supports multitasking, which turns the projector into a minicomputer.

There are nuances when using wireless mice with receivers. Some cheap models may have a signal delay or conflict with a 2.4GHz Wi-Fi projector module. If the cursor is moving in jerks, try pushing back. USB-projector-body receiver by means of a short USB-This will reduce interference and improve responsiveness.

Control over HDMI-CEC from another device

HDMI-CEC (Consumer Electronics Control) technology allows devices connected via HDMI to control each other. If your Xiaomi projector is connected to a TV, receiver, or even a laptop that supports this feature, you can use the remote from this device to control the projector menu, which is especially convenient if the projector remote is lost, but there is a TV remote at hand.

This feature needs to be activated in both device settings. On Xiaomi projectors, this option is usually in Settings → Device → Managing HDMI devices. Since it is difficult to get into the menu without a remote, this method works best if the settings were made in advance or if the projector automatically picks up the signal. Some models activate the CEC by default.

⚠️ Note: Not all cables HDMI If this doesn't work, try replacing the cable with a High Speed certified Ethernet cable.

The advantage of this method is that you don't have to look for additional gadgets or install apps. You just take a remote from a Samsung TV (Anynet+), LG (SIMPLINK) or Sony (Bravia Sync) and control the projector. However, the functionality can be limited to basic commands: turn on, turn off, adjust volume and navigate the main menu items. Specific focus or light source settings through the CEC are usually not available.

If you use a projector in conjunction with an Apple TV or Android TV, make sure that their settings also include the option to control external devices. Sometimes the projector can perceive the console as a device and allow it to dictate its terms, which can lead to conflicts, in which case it is easier to temporarily disable the CEC in the settings of the consoles.

Use of USB Debugging Mode (ADB)

For advanced users who are not afraid of the command line, there is the most powerful management method – the protocol. ADB (Android Debug Bridge: This tool allows you to send commands to the projector directly through the projector. USB-It's a back door to Android, and it works even if the interface freezes, and it's a back door to the Android system.

To use this method, you first need to activate the developer mode. Go to Settings → About device and quickly click 7 times on the item "Build Number." After that, the "Developers" section will appear in the menu where you need to turn on "Debugging over USB." If you can't get to the menu due to the lack of a remote, this step, unfortunately, will have to be skipped, the mode was turned on earlier. However, if the projector is already connected to the PC before, the connection can be established automatically.

adb connect 192.168.1.55


adb shell input keyevent KEYCODE_HOME

The above is an example of a command that connects to a projector on IP-It emulates the press of the home button. There are many codes for different actions: KEYCODE_DPAD_UP (upward), KEYCODE_ENTER (input), KEYCODE_BACK (You can download pre-made scripts or use graphical shells. ADB, The Android Debug Bridge GUI, wherein the commands are represented as buttons.

This is a method that is indispensable if the projector interface is locked or not working properly. ADB You can even install a remote application directly on the projector, if it is available in the form of a APK-The main requirement is to have a PC or laptop at hand and knowledge IP-Projector addresses on the local network.

Emergency switching on and resetting settings

When the projector needs to be turned on or restarted urgently, and the remote and other methods are not available, there are still physical manipulations. Most Xiaomi and Mijia models have a hidden power button, which is often located on the back, near the ports, or combined with the focus button. A short press usually turns on the device, a long one turns off or puts it into standby mode.

If the system is stuck and doesn't respond to any commands, you need to force a reboot, which requires you to turn off the power cable from the outlet, wait 10-15 seconds for the capacitors to fully discharge, and turn on again. Some models have a small Reset hole where you press a clip for 5-10 seconds, which will return the device to factory settings, which can solve software errors, but delete your data.

💡

If the power button does not respond, try to pinch it simultaneously with the Back button (if it is on the case) when connecting the power - this can start Recovery mode.

It is worth noting that after resetting the projector may require initial setup, including language selection and Wi-Fi connection. Without the remote, this stage can become difficult, so prepare in advance. USB-In recovery mode, navigation is often done with volume buttons (if any) or simply a power button to select a point.

For models with a laser light source, it is important not to overload the device with frequent on-off cycles. Let the system complete the cooling processes of the fans before restarting. Ignoring this rule can shorten the life of an expensive laser module.
