Xiaomi's remote control from a TV is not just a channel switching device; it's a multifunctional gadget with Bluetooth, IR transmitter and even voice control. But how does it interact with a TV? Why do buttons sometimes fail and other times the remote works 10+ meters? In this article, we'll go into detail the operation, technical features and hidden capabilities of the Mi TV remotes, and learn how to fix typical malfunctions.
Xiaomi remotes are structurally different from classic IR devices, combining several communication technologies that allow you to control not only the TV, but also other devices of the Mi Home ecosystem. For example, Mi TV Remote Pro or Mi TV Stick Remote models support two-way communication โ the TV can send notifications to the remote control about low battery charge or software updates. And in new versions (for example, for Xiaomi TV Q2 2023) an automatic search function is added โ if the remote is lost, it can be โcallโ through the TV menu.
But how does it work at the technical level? What protocols are used to transmit a signal, and why does the remote sometimes stop responding to pressing? Let's take a look at the basics to advanced features.
Device and technical characteristics of the Xiaomi TV remote
Xiaomi's TV remotes are split into generations, but the overall design remains similar.
- ๐ Rechargeable battery (lithium-polymer, capacity 300-500 mAh) with support for charging on USB-C or Micro-USB (old models).
- ๐ก Bluetooth module (version 4.2 or 5.0) for two-way communication with the TV.
- ๐ฆ Infrared transmitter (IR) for compatibility with other devices (air conditioners, audio systems).
- ๐ค Microphone (in voice-controlled models, such as the Mi TV Remote Pro).
- ๐ Gyroscope (in remotes with Air Mouse support - for controlling the cursor gestures).
The main difference from traditional remotes is the use of Bluetooth Low Energy (BLE) instead of the classic IR signal.
- ๐ถ Control the TV through walls (range up to 10-15 meters).
- ๐ Receive feedback (e.g. vibration when pressed or notified).
- ๐ Save battery power (BLE consumes 5-10 times less power than a classic Bluetooth).
But there are downsides to this solution, such as signal delays with BLEs of 50 to 100 milliseconds (versus 10 to 20 milliseconds for IR), which is noticeable when you switch channels quickly, and Xiaomi uses a proprietary protocol over BLE, making it difficult to be compatible with other brandsโ TVs.
How the remote controls communicate with the TV: protocols and paired codes
The process of connecting the remote to the Xiaomi TV consists of several stages:
- Detection: The TV scans the airwaves for available BLE devices named MiTV-Remote-XXXX (where XXXX is a unique identifier).
- The console and the TV exchange paired codes (similar to PIN- code for Bluetooth devices). In newer models, this process is automated, in older models (before 2020 years), sometimes it was required to enter the code manually.
- Authentication: The TV authenticates the remote with a digital signature (using the AES-128) algorithm.
- Synchronization: Devices communicate about supported functions (e.g., the presence of a microphone or gyroscope).
Once paired, the remote and the TV form a closed network with an encrypted channel, which protects against interception and random taps (for example, if a neighbor is also operating a Xiaomi TV), but if the remote is paired with several TVs, it can conflict - respond to commands from the wrong device, in which case resetting the connections helps (we will discuss this below).
Interesting fact: Xiaomi TV firmware had a bug in it until 2021 that allowed you to connect someone else's remote without confirmation, which was used to hack public TVs (such as hotels), and the new versions of the software have eliminated the vulnerability, but some models still support guest mode - limited control without full pairing.

Button functions and hidden capabilities
Keys on Xiaomi remotes are divided into three groups:
- The main ones are: power, volume control (Vol+/-), channel switching (CH+/-).
- Multimedia: launch Netflix, YouTube, Prime Video (configurable in the TV menu).
- System: Home (main screen), Back (back), Menu (settings), Google Assistant (voice assistant).
But there are also hidden functions that many people do not know about:
- ๐ Double-click Home: Opens a list of recently launched apps (similar to multitasking on a smartphone).
- ๐ฎ Hold OK + Vol-: activates Game Mode (reduces input latency for games).
- ๐ Triple press Menu: shows the battery level of the remote (does not work on all models).
- ๐ฑ Mi Button (Mie button): triggers Mi Share to transfer files from your smartphone to your TV.
In remotes with a gyroscope (for example, Mi TV Remote Pro), Air Mouse is available - gesture cursor control, like on a smartphone.
- Hold the OK button for 3 seconds.
- On the screen will appear cursor โ now you can โdriveโ remote in the air.
- To return to normal mode, press back.

If the remote buttons start to stick, wipe them with an alcohol napkin, often due to accumulated dust or grease. Do not use aggressive detergents!
Typical malfunctions and ways to eliminate them
Even the most reliable Xiaomi remotes sometimes fail, and letโs look at the most common problems and their solutions:
| Problem. | Possible cause | Decision |
|---|---|---|
| Remote is not responding to pressing | Battery discharged, coupling failure | Charge the remote, reconnect through Settings โ Bluetooth |
| Buttons are running with a delay | Weak Bluetooth signal, interference from other devices | Restart the TV, reduce the distance to the remote control |
| Multimedia buttons (Netflix, YouTube) are not working. | Resetting application settings | Reconfigure the buttons in Settings โ Remote โ Configure the keys |
| The remote controls someone else's TV | Conjugation conflict (the remote is tied to several TVs) | Reset connections: Settings โ Bluetooth โ Forget the device |
| The microphone is not working (voice search) | Contaminated microphone, disabled access in settings | Clean the microphone hole, check the permissions in Settings โ Privacy |
If the remote has stopped responding completely, try a hardware reset:
- Remove the battery (if removable) or hold the Power + Home for 10 seconds.
- Connect the remote to charge for 30 minutes (even if the indicator is not on).
- Reconnect via the TV menu: Settings โ Devices โ Add remote.

How to connect Xiaomi remote to another TV or device
Xiaomi remotes can be used not only with the TVs of this brand, for example, models with an infrared transmitter are compatible with air conditioners, audio systems and even some projectors.
- Hold Menu + Vol+ for 5 seconds until the indicator blinks.
- Direct the remote to the device and enter the manufacturer's code (the list of codes is in the instructions for the TV).
- Check the buttons โ if all is correct, the remote will save the settings.
To control TVs of other brands (such as Samsung or LG) you will need:
- ๐ฑ Install the Mi Remote app on your smartphone (available for Android and iOS).
- ๐ Connect the remote to your phone via Bluetooth.
- ๐ Select a TV model in the app and adjust the buttons.
Note: full work is possible only with TVs on Android TV or Google TV. For devices on Tizen (Samsung) or webOS (LG), only basic functions (on, volume, channel switching) are available.

Xiaomi remotes with Bluetooth 5.0 support simultaneous connection to two devices (for example, a TV and a soundbar), but to do this you need to activate Dual Mode mode in the settings.
Update of the remote firmware: why and how to do it
Like any gadget, Xiaomi remotes receive firmware updates.
- ๐ Fixing bugs (e.g. button hovers).
- ๐ Addressing security vulnerabilities.
- ๐ Add new features (e.g. gesture support in Air Mouse)
The update is automatic when you connect to the TV, but sometimes you need to manually install it.
- Download the latest firmware version from the official Xiaomi website (Support โ TV Accessories section).
- Unpack the archive and copy the remote_update.bin file to the flash drive (to the root directory).
- Insert the flash drive into the TV and go to Settings โ About the device โ Update the remote.
โ ๏ธ Warning: Don't turn off the TV during the upgrade! If the process stops, the remote may stop working, in which case you will need to restore through service mode (instruction below).
