How to turn off Xiaomi projector from your phone: the full guide

Xiaomi’s digital projectors are no longer just bulky display devices, becoming full-fledged multimedia centers that can be controlled remotely. Often, users are faced with a situation where the physical remote is lost, discharged or simply out of reach, and the question arises about how to turn the projector off the phone. Fortunately, the Android ecosystem and the Chinese giant’s proprietary software provide several effective ways to solve this problem without having to get out of the couch.

In this article, we will take a look at all the available remote shutdown methods, from standard smartphone features to specialized smart home apps. You will learn how to turn your Xiaomi smartphone or a device based on another version of Android into a universal remote control, and also look at the nuances of working with Mijia and Wanmo series projectors. Understanding these processes will allow you not only to comfortably complete your movie viewing, but also to customize automatic scripts for your home theater.

Before we get to specific instructions, it’s important to note that the success of the operation depends on the type of connection and the version of the operating system installed on the projector itself. Most modern models run a modified version of Android TV, which opens up wide possibilities for integration with mobile gadgets. However, there are simpler models that require an infrared port on the phone or the use of third-party emulators.

Use of the Mi Remote Infrared Port

The most reliable and versatile way to work even without a Wi-Fi connection is to use an integrated infrared transmitter. Many Xiaomi, Redmi and POCO smartphones feature an IR Blaster module located on the upper end of the case. The standard Mi Remote app is already pre-installed on most devices and contains databases for thousands of models of equipment, including projectors.

To get started, you need to launch the app and click on the add button for a new device. In the category list, you should choose Projector or TV, as many projectors use the same codes as TVs. After that, the system will prompt you to choose a brand; if Xiaomi or Wanmo is not on the list, you can try universal codes or choose the nearest optics manufacturer, such as BenQ or Epson, since protocols often overlap.

⚠️ Attention: Infrared signal requires direct visibility between the phone and the projector receiver. Make sure there are no obstacles between the top edge of the smartphone and the front panel of the device, otherwise the shutdown command will not be executed.

The pairing process involves checking multiple buttons on the phone screen, you'll need to confirm if the projector is responding to virtual keystrokes. Once the connection is established, you get full control of the device, including the power, volume and navigation buttons, which is especially useful when you need to turn off the equipment urgently, and the main remote is lost in the bowels of the sofa.

Managing through the Mi Home app for smart home

If your projector is part of the Mijia smart device line, the most convenient way to manage it is the Mi Home app, which requires both the smartphone and the projector to be on the same local Wi-Fi network, and that the projector itself be logged into your Mi Account, making management a fully interactive process.

Once you add a projector to the device list in the Mi Home app, you get access to an advanced control interface, which not only has a switch off button, but also monitors the lamp status, system temperature and operating time. Pressing the power icon in the app sends a digital signal to the device, allowing all processes to be completed correctly before shutting down, which prolongs the life of the projector.

  • πŸ“± Open the Mi Home app and make sure the region in the settings matches the region of the projector account.
  • πŸ“‘ Check that your smartphone is connected to the same Wi-Fi network as the projector (important for 2.4GHz networks).
  • πŸ”Œ Click on the projector icon in the list of devices and select the off button in the lower control menu.
  • βš™οΈ When first connected, you may need to confirm on the projector screen via a virtual remote.

The thing about this method is that you can create automation, and you can set up a scenario where the projector turns off automatically at a certain time or when you're in a different situation, like when you leave your home (geolocation), which makes the system really smart and eliminates the need for manual intervention every time.

πŸ’‘

If the projector is not displayed in Mi Home, try resetting the network settings on the projector itself via the System -> Network menu and re-doing the pairing procedure by holding the buttons on the remote (or virtual remote in Mi Home).

Remote Emulator Apps for Android TV

Since most of the advanced Xiaomi Projector models are based on the Android TV operating system or its modifications, they support standard remote control protocols. For owners of smartphones without an infrared port, third-party applications from the Google Play store, such as Google TV, Android TV Remote Control or universal remotes like Universal TV Remote, will be an excellent solution.

The way these applications work is by sending commands over a local network, and once you put the app on your phone, it scans the network for compatible devices, and when the projector is found, it can have a confirmation code that you want to type into your smartphone, and after a successful pair, the phone becomes a complete replacement for a physical touchpad and voice input remote.

Using third-party emulators gives the advantage of a keyboard, which is convenient for entering search queries on YouTube or Netflix running on the projector. However, it is worth considering that when you turn off the projector through such applications, the device can go into deep sleep mode, rather than turning off completely, if the corresponding function is not activated in the energy saving settings of the projector itself.

Why can't the app see the projector?
A common problem is is isolating customers on the router. If you have AP Isolation or guest network enabled, devices may not be able to see each other. Make sure that both gadgets are on the same main network.

Voice control via Google Assistant and Alice

Integration of the projector with voice assistants is the pinnacle of convenience in today’s smart home. If your Xiaomi Projector supports Google Assistant or, in the case of regional versions, Yandex Alice (through smart home skill), you can turn off the device with a simple voice command, which is especially true when your hands are busy or the room is dark.

To configure this feature, you need to link your Mi Home account to your voice assistant account. In the Google Home or Yandex application, you need to find the Smart Home section, select the addition of a device and find it in the Xiaomi list. After authorization, all compatible devices, including the projector, will appear in the general list of managed equipment.

The commands can sound different: "OK, Google, turn off the projector" or "Alice, turn off the theater." It's important that the name of the device in the smart home system is clear and unique. Voice control often works faster than finding an app on the phone, and creates a sense of magic when the technique is listened to at the first word.

⚠️ Attention: Voice control requires a stable internet connection.If the network is congested or the provider is experiencing problems, the command may not reach the server and be executed, so have a backup way to turn off.

Configuring automatic shutdown scenarios

One of the most useful features of Xiaomi's ecosystem is the ability to create complex automation scenarios, so you can set the system up so that the projector turns off automatically when certain conditions occur, which will save you from even having to pull out your phone, and this is done through the "Scenarios" tab in the Mi Home app.

For example, you can create a movie over scenario that turns off the projector at 23:00, mutes the smart lights, and closes the smart curtains, or a geolocation-activated scenario where your phone leaves the radius of your home Wi-Fi network, the projector shuts down, saving the lamp life and electricity.

You should also consider using a sleep timer if you have one in the interface of the projector itself or the app being broadcast (like YouTube Kids or online cinemas), which is often safer for the system than a sudden power cut, and allows you to complete all background processes.

πŸ’‘

Automation is not just a convenience, but also a way to extend the life of the device, eliminating the human factor and forgetting to turn off the equipment manually.

Solution and troubleshooting

Despite the convenience of digital control, users may face various technical problems, most often associated with device desynchronization or network failures, if the phone stops β€œseeing” the projector or the commands are not executed, the first thing to check the basic parameters of the connection.

It is a common mistake to operate devices across different frequency bands (2.4 GHz and 5 GHz), although modern routers usually combine them into a single network, and problems can arise after updating the router's firmware or the projector itself, in which case a simple restart of network equipment helps.

  • πŸ”„ Reboot the router and projector, disconnecting them from power on 10-15 seconds.
  • πŸ“‘ Check if the Mi Home app or the remote in the Google Play store has been updated.
  • πŸ”’ Make sure the projector does not have guest network mode or access restrictions on it.
  • πŸ“± On your phone, try to forget the Wi-Fi network and connect again by entering a password.

If nothing helps and the projector is frozen, emergency shutdown may be required, in which case, if software methods are not available, only the physical disconnection of the power cord or the use of a button on the device body (if available), however, regular use of this method is not recommended.

⚠️ Warning: Never use the forced power outage method regularly.This can damage the Android file system TV, installed on the projector, and will require complex firmware recovery.
