How to turn on and configure the remote on Xiaomi Redmi Note 9 Pro: full instructions with a photo

Xiaomi Redmi Note 9 Pro is one of the few mid-range smartphones that has retained an infrared port (IR port) for managing household appliances. However, many users face the problem: the remote in the menu does not display, does not respond to commands or is not at all in the firmware. In this article, we will discuss all ways to turn on the remote, from basic activation to restoring work through hidden settings.

It is important to understand that the functionality of the remote control depends on the version of MIUI and regional firmware. For example, in the global versions (MIUI Global), the Mi Remote application can be removed by default, and in the Chinese ones (MIUI China) it can require additional settings. We will consider solutions for all cases, including restoring the IR port after resetting or updating the firmware.

If you've never used a remote on your Redmi Note 9 Pro, first check if there's a small black window on the top of the device -- that's the IR transmitter -- and without it, you can't control the hardware, even if the software is configured correctly.

1. Check for the availability of an IR port on the Redmi Note 9 Pro

Before you set up the remote, make sure your smartphone supports this feature physically. On the Redmi Note 9 Pro (model number M2003J6A1G for the global version), the IR port is located to the right of the headphone jack. Here's how to identify it:

• 🔍 External inspection: On the upper edge of the body (near the speaker) there should be a small black glass the size of the body. ~2mm If it is not available, your modification does not support IR control.
• 📱 Check through Settings: Go to Settings → The phone. → The Sensors section should have an Infrared Port.
• 🛠️ Diagnostics via the Engineering Menu: Enter the code ##4636## in the phone application, select Phone Information and check the list of sensors.

If you have an IR port, but the remote doesn't work, the problem may be in the firmware or services that are disabled, and in the next section, we'll talk about how to activate the function software.

2. Activate the remote via the standard Mi Remote app

In most cases, the app is used to control the equipment, Mi Remote (formerly Mi Remote Controller), but after the MIUI updates, it may disappear from the menu.

1. Search the app menu: Scroll through all screens or search the system (guest down on the home screen). Enter the request for "remote" or "remote".
2. Installation from Mi App Store: If the app is removed, download it from Xiaomi's official store: Open the App Store. Search for Mi Remote. Install the app from developer Xiaomi Inc.

Activation through settings

Settings → Connected devices → remote control

Once installed, Mi Remote will require permission to use the IR port. Allow access to the Camera (required for scanning). QR-Device codes) and Warehouse (to save settings).

3. Adjustment of control equipment: step-by-step instructions

When Mi Remote is installed, you have to add control devices, and the interface is intuitive, but there are nuances for different types of technology.

1. Category Selection: Launch Mi Remote, press + Add device and select type (TV, air conditioner, projector, etc.).
2. Model Search: Type a brand name (such as Samsung) manually or select from a list. There are several protocol options available for popular brands.
3. Testing commands: After selecting a model, click the Test, the smartphone will send a signal to turn on. If the TV does not respond, try another protocol from the list.
4. Save settings: Save a successful protocol under a convenient name (for example, “TV Hall”).

For air conditioners and split systems, the process is more complicated: you will need to specify the mode (cooling/heating), temperature and fan speed. Some models (for example, Daikin or Mitsubishi) require manual code entry from the instructions.

💡

If your device is not found in Mi Remote, try choosing the closest model of the same brand to the next in functionality, for example, a rare Philips 2010 TV will fit the protocol from the 2015 model.

4. Problem Solving: The remote is not working or does not find the device

If Mi Remote is installed but commands are not sent, the reasons may be as follows:

Pay special attention to the energy saving mode. MIUI aggressively optimizes background processes, which causes the IR port to shut down after 5-10 minutes of inactivity.

1. Go to Settings → Battery → Battery Optimization.
2. Find Mi Remote in the list and select No Limits.
3. Activate the AutoRun option for the application.

Another common problem is the case conflict, and if you're using a bumper or a high-sided case, it can block the IR transmitter, and before setting up, remove the case or check if the port window is closed.

7. Update the device base in Mi Remote

The Mi Remote database of supported devices is updated online, and if your model is new (released less than a year ago), it may not be on the list.

1. Open Mi Remote and go to Settings → Update the device base.
2. Connect to Wi-Fi (update via mobile internet may not work).
3. Wait until the download is complete (it can take up to 5 minutes).
4. Restart the app.

If the update doesn’t help, try resetting Mi Remote:

1. Go to Settings → Applications → Application Management → Mi Remote.
2. Press Warehouse. → Clear the data.
3. Reboot your smartphone.

After reset, all stored devices will be deleted, but the protocol database will be updated to the latest version.
