It's important to understand that a sleep timer is a one-time action, and when you turn off the TV, you reset the setting, and the next time you turn on the timer, you have to re-activate it, so that the device doesn't turn off spontaneously during normal daytime viewing.

Use of timer through Mi Remote app

If the built-in interface seems uncomfortable or hidden, you can use the official Mi Remote app on your smartphone. Remote control provides extended access to TV features, including power management and timers. This is especially convenient when the remote is far away or lost.

To get started, make sure your smartphone and Xiaomi Mi TV 4S are connected to the same Wi-Fi network. Launch the app, select your TV from the list of devices. The remote interface often has a button or menu that duplicates the physical remote, including calling the timer menu.

Some versions of the app allow you to create automation scenarios, so you can set a rule that will turn off the TV at certain times of the day, and it's more flexible than a standard countdown timer.

📱 Open the Mi Remote app and connect to TV.
⏱ Find the clock icon or the “Timer” menu in the application interface.
🔌 Select the “Switch Off” action and set the execution time.
✅ Save the script for automatic launch.

Using third-party remote apps is also possible if the official app doesn't support your model completely.Many Android remote emulators have timer widgets on the home screen, which speeds up access to the feature.

Use the timer widget on the smartphone’s home screen for quick access to the TV turn off feature without going into the deep settings menu.

Set up parental controls to limit time

An alternative way to limit TV hours is to use parental controls, and although this is not a classic countdown timer, it allows you to tightly regulate the time when the TV can run, which is useful if you want to limit the time of viewing for children.

In the Xiaomi Mi TV 4S settings, you can find the "Security" or "Parental Control" section, which creates a limited user profile, you can set a schedule, for example, allow viewing only from 18:00 to 21:00, outside of this time, the TV will either not turn on or block content.

To set limits often requires the creation of PIN-This will prevent children from changing their settings or accidentally resetting the timer, and the system will automatically block access to the interface after the allotted time has expired.

Function	Description	Where to find out.
Sleep timer	Countdown to shutdown	Settings → Preferences
Parental control	Scheduled limitation	Security → PIN-code
Eco-regime	Auto-Day Sleeping When Inactivity	Settings → Energy saving
Application timer	Time limit for a specific software	Digital well-being

It is worth noting that parental control settings can be reset when the TV is completely reset to factory settings. PIN-code or write it in a secure location.

Advanced method: timer through ADB commands

For users who want to gain full control of their Xiaomi Mi TV 4S, there is a method of using the ADB (Android Debug Bridge) debugging bridge, which allows you to send system commands directly, bypassing the GUI, and this is the most reliable way to create a custom timer.

To start, activate the developer mode on your TV. Go to Settings → About TV and quickly press 7 times on Build number. After you see a message about activating the developer mode, log in to the Developer menu and turn on ADB debugging.

Now you will need a computer with installed ADB installer ADB Directly to the phone. IP-The command to turn off the TV looks like input keyevent 26 (power button) or a softer option for sleep.

adb connect 192.168.1.XX


adb shell input keyevent 26

You can create a script that will execute this command at a given interval, for example, using the task scheduler on the PC or the script on the TV itself (if you have root rights or a terminal installed), which allows you to create a timer with an accuracy of a second.

⚠️ Attention: Misuse of the right ADB commands can cause system instability. Use only verified commands to control power.

Automation with Google Assistant and Smart Home

Integrating Xiaomi Mi TV 4S with the Google Home ecosystem opens up new possibilities for automation. If your TV supports Chromecast built-in (which is relevant for global versions), you can control its turn off by voice or through smart home scenarios.

You can create a "Goodnight" routine in the Google Home app, and you can add "Switch off the TV" to that routine, and by running that routine on a schedule or by voice command, you're guaranteed to turn off the device even if you forgot to manually do it.

There are also geo-responsive scenarios, for example, if all the smartphones in the house are geo-fenced, the TV can turn off automatically, which requires more complex adjustments, but provides maximum energy efficiency.

☑️ Checking before setting up ADB

Resolving timer and auto-switching problems

Sometimes users are faced with a situation when the timer does not work or the TV turns off prematurely, often due to energy saving settings that take precedence over user timers, check the settings of Eco Mode or Automatic Sleep Mode.

If the TV turns off itself after 4 hours of inactivity, this is a system restriction of Android TV, which protects against the burnout of the matrix. It can be turned off in the settings, but it is not recommended to do this, and the cause may be overheating of the device, which activates the emergency shutdown.

In case of a software failure, cleaning the cache of system applications can help. Go to Settings → Apps → Show System → Settings and select “Clear Cache.” This will not delete your data, but can correct the errors in the logic of the timers.

Hidden remote commands

On some Xiaomi remotes, prolonged retention of the “Menu” button or the combination “Back + Home” can cause hidden service menus, where there is also access to timers, but logging in there is at your own risk.
