3. Click Add Device and select the category of equipment (TV, air conditioning, etc.).
4. Follow the on-screen instructions: The app will suggest selecting a device brand from a list or manually testing commands.

If the Remote app is not available, it means that your Redmi model does not support IR functions at the software level (even if you have a physical port), in which case try third-party solutions, which we will discuss below.

Ensure that the IR port is available (visually or through specifications)

Update MIUI to the latest version (Settings → About Phone → System Update)

Download the application "Remote" from MI App Store (if not available in the system)

7.Security and limitations when using an IR port

Despite the convenience, the use of an IR port has some nuances that are worth remembering:

Security vulnerabilities

The infrared signals are not encrypted, so in theory they can be intercepted with special equipment, but in practice this is unlikely in a domestic environment.

• 🔒 Do not use an IR port to manage smart locks or security systems.
• 📱 Disable access to the Remote app for third-party services (for example, in application resolution settings).

Range and angle restrictions

The infrared signal is only propagated in a straight line and blocked by obstacles.

• 📏 Maximum distance - 5-7 meters (depending on the model of technology).
• 🎯 The angle of deviation from a straight line shall not exceed 30 degrees.

Compatibility with technology

Not all devices support control via an IR port, for example:

• ❌ Modern Samsung TVs QLED (2020+) often used only Wi-Fi/Bluetooth.
• ❌ Mitsubishi Electric Air Conditioners Require Special Adapters.
• ✅ Most budget TVs (TCL, Hisense and air conditioners (Ballu, Electrolux) are fully compatible.
