Smart plugs are handy devices for controlling your home appliances remotely. But can they turn on your TV? This question is common among smart home users looking to automate their entertainment systems. In this post, we’ll explain how smart plugs work with TVs, whether they can turn a TV on, and what alternatives exist if they can’t. We’ll also cover safety tips and how to check if your TV is compatible.
What is a Smart Plug?
A smart plug is a small device that plugs into a standard wall outlet. You can plug any appliance, like a TV, into the smart plug. Using a smartphone app or voice assistant, such as Amazon Alexa or Google Assistant, you can turn the appliance on or off remotely. Some smart plugs also let you set schedules or monitor energy use.
Smart plugs are easy to set up and affordable, making them popular for smart home beginners. They work by controlling the flow of electricity to the connected device. For example, you can turn off a lamp or fan with a tap on your phone.
How Do Smart Plugs Work with TVs?
Smart plugs can control the power supply to a TV, allowing you to turn it off by cutting the electricity. This is similar to unplugging the TV from the wall. However, turning the TV back on is not always possible with a smart plug alone.
The Standby Mode Issue
When you turn off a TV using its remote, it doesn’t fully power down. Instead, it enters standby mode, a low-power state where the TV waits for a signal to turn back on. In standby mode, the TV uses minimal electricity and can respond to the remote or power button.
A smart plug cuts all power to the TV, effectively shutting it down completely. When you use the smart plug to restore power, most TVs return to standby mode, not fully on. This means you’ll still need to press a button on the remote or TV to turn it on.
Why This Matters
For devices like fans or lamps, a smart plug works perfectly because they turn on immediately when power is restored. TVs, however, require an additional step to exit standby mode. This limitation makes smart plugs less effective for turning on most TVs.
Can Some TVs Be Turned On with a Smart Plug?
Yes, some TVs can be turned on with a smart plug, but it depends on the TV’s features. Certain models, especially those designed for commercial use or digital signage, have an auto power-on setting. This feature makes the TV turn on automatically when power is restored.
How to Check for Auto Power-On
To find out if your TV supports this feature, try these steps:
- Check the Manual: Look for terms like “Auto Power On,” “Power On Behavior,” or “Startup Settings” in your TV’s user manual.
- Explore Settings Menu: Navigate to the TV’s power or system settings. Look for options related to power management.
- Search Online: Search for your TV model plus “auto power on” to see if other users have discussed this feature. For example, some Samsung TVs support this via HDMI-CEC settings .
- Contact Support: Reach out to the TV manufacturer’s customer service for clarification.
Examples of TVs with Auto Power-On
While specific models vary, TVs used in public spaces, like lobbies or stores, often have this feature. For instance:
- Samsung Commercial Displays: Some models include auto power-on for signage purposes.
- Roku TVs: Certain Roku TVs may have auto power-on, though it’s not universal.
- Insignia Models: Some Insignia TVs support “TV Auto Power On” via HDMI-CEC.
If your TV has this feature, a smart plug can turn it on by restoring power. However, this is not common in most consumer TVs.

Alternatives to Using Smart Plugs for Controlling TVs
If your TV can’t be turned on with a smart plug, there are other ways to automate or control it remotely. Here are some effective alternatives:
HDMI-CEC Devices
HDMI-CEC (Consumer Electronics Control) allows devices connected via HDMI to control each other. For example:
- Chromecast with Google Home: If your TV supports HDMI-CEC (e.g., LG SimpLink or Samsung Anynet+), saying “Hey Google, play Netflix on TV” can turn on the TV and start playback.
- Amazon Fire Stick with Alexa: Similar to Chromecast, Alexa can control the TV via HDMI-CEC.
To use this, ensure HDMI-CEC is enabled in your TV’s settings and pair the device with a compatible voice assistant.
Smart Home Hubs
Smart home hubs like the Logitech Harmony Hub can control TVs using infrared (IR) signals or Wi-Fi. You can set up routines to turn the TV on or off with voice commands like “Alexa, turn on the TV” .
IR Blasters
IR blasters mimic a TV remote’s signals to turn the TV on or off. Devices like Broadlink or cheap smart IR blasters can be controlled via apps or voice assistants.
Smart TV Features
Many smart TVs have built-in scheduling or voice control options. For example:
- Samsung Smart TVs: Allow scheduling power on/off times.
- Roku TVs: Support voice control via Alexa or Google Assistant.
Check your TV’s settings or manual for these features. Learn more about smart TV capabilities at Teckwiki Smart TV Guide.
Safety Considerations
Using a smart plug with a TV is generally safe, as it’s similar to unplugging the device. However, keep these points in mind:
- Avoid Power Cuts During Updates: Cutting power during a firmware update could cause issues. Wait until updates are complete before using the smart plug.
- Check Wattage Compatibility: Ensure the TV’s power draw doesn’t exceed the smart plug’s capacity. Most smart plugs handle TV wattage, but check the plug’s specifications.
- Use Surge Protection: Pair the smart plug with a surge protector to safeguard your TV from power surges.
Research suggests that cutting power to a TV doesn’t cause significant harm, as TVs are designed to handle power interruptions.
How to Check if Your TV Can Be Controlled with a Smart Plug
To determine if a smart plug can turn on your TV, follow these steps:
- Review the Manual: Look for information on power settings or auto power-on features.
- Check Settings: Navigate to the TV’s power or system settings for “Auto Power On” or “Quick Start” options.
- Test with a Smart Plug: Plug the TV into a smart plug, cut power, and restore it to see if the TV turns on automatically.
- Research Online: Search for your TV model with terms like “auto power on” or “smart plug compatibility.”
- Contact Manufacturer: Ask customer support if your TV supports auto power-on.
If your TV doesn’t support this feature, consider the alternatives listed above. For troubleshooting TV power issues, see Teckwiki Samsung TV Fixes.
Conclusion
Smart plugs are great for turning off TVs by cutting power, but turning them on is usually not possible due to the standby mode. Some TVs with auto power-on features can work with smart plugs, but this is rare in consumer models. If your TV doesn’t support this, alternatives like HDMI-CEC devices, smart home hubs, or IR blasters offer better control. Always check your TV’s settings or manual to confirm compatibility, and ensure safe use by following wattage and surge protection guidelines.
By understanding your TV’s capabilities and exploring smart home options, you can create a convenient and automated entertainment setup.
