Living Room Tech: TVs as Smart Home Hubs

Your television is no longer just for watching shows — it can now act as the central control panel for your entire smart home. By connecting to your Wi-Fi network and using built-in voice assistants and protocols like Matter, a modern smart TV lets you control lights, thermostats, cameras, and speakers from one screen or with your voice. This article explains how TVs became smart home hubs, what they can and can’t do, and how to set yours up effectively.

From Display to Dashboard: How We Got Here

For decades, the TV was a passive device — you turned it on, picked a channel, and watched. The shift began with internet-connected “smart TVs” in the late 2000s, which added streaming apps. But those early models were slow and had clunky interfaces. The real turning point came when TV operating systems (like Google TV, Roku OS, and Samsung Tizen) added voice assistants and support for smart home protocols.

Meanwhile, smart home devices themselves became more standardized. The introduction of Matter in 2022 — a unified connectivity standard backed by Apple, Google, Amazon, and Samsung — made it possible for a TV to talk to a light bulb from a different brand without needing a separate bridge. Today, many TVs ship with a built-in hub that can directly control Matter-compatible devices, even when the TV is in standby mode.

What a TV Hub Can Actually Do

A TV acting as a smart home hub means it can receive commands, process them, and send them to other devices — without requiring a separate hub like a smart speaker. Here are the core functions:

  • Voice control: Built-in microphones (or far-field mics on some models) let you say “Turn off the living room lights” or “Set the thermostat to 72 degrees.”
  • On-screen dashboard: Most smart TV platforms have a dedicated smart home panel showing all connected devices, with toggles and sliders for control.
  • Automation triggers: You can create routines like “When I turn on the TV, dim the lights” using the TV’s built-in automation engine.
  • Camera feeds: Many TVs can display live feeds from connected security cameras, either in a small window or full-screen.
  • Matter controller: If your TV supports Matter, it can serve as the controller for Matter devices, even when the screen is off (as long as it’s plugged in and connected to power).

However, a TV hub is not a full replacement for a dedicated hub like a HomePod or Echo. It typically lacks the same level of support for older Zigbee or Z-Wave devices, and it may not have the processing power to handle complex automations with many devices.

How the TV Connects to Your Smart Home

There are three main ways a TV communicates with smart devices:

  1. Wi-Fi: Most smart home devices (like Wi-Fi-enabled bulbs and plugs) connect directly to your router. The TV, also on Wi-Fi, can discover and control them via the cloud or locally using IP.
  2. Bluetooth: Some devices (like certain speakers and locks) use Bluetooth. The TV can pair with them for short-range control, though this is less common for whole-home automation.
  3. Matter over Thread or Wi-Fi: Matter devices can be controlled by the TV if the TV has a Thread border router (some models do) or if it supports Matter over Wi-Fi. This is the most interoperable method.

Most TVs do not have Zigbee or Z-Wave radios, so they cannot directly control those devices. If you have older smart home gear using those protocols, you’ll need a separate hub (like a smart speaker or a USB dongle) that bridges them to the TV.

Setting Up Your TV as a Hub

To turn your TV into a smart home hub, follow these general steps (exact menus vary by brand):

  1. Connect to Wi-Fi: Ensure the TV is connected to your home network and has a stable internet connection.
  2. Sign in to your smart home account: On the TV, go to Settings → Smart Home (or similar). Sign in with the same account you use for your smart home app (e.g., Google Home, Amazon Alexa, or SmartThings).
  3. Enable the hub feature: Look for a setting called “Smart Home Hub,” “Matter Hub,” or “Voice Assistant.” Turn it on.
  4. Add devices: Open the TV’s smart home app and scan for nearby devices. You may need to put your devices in pairing mode.
  5. Test voice control: Press the voice button on the remote (or say the wake word if the TV has far-field mics) and try a command like “Turn on the kitchen light.”

If you have a separate smart speaker, you can also link it to the TV so that both can control the same devices.

Choosing a TV for Smart Home Duty

Not all TVs are equal as hubs. When shopping, consider these factors:

  • Matter support: Look for TVs that explicitly state “Matter controller” or “Matter hub” in the specs. This ensures future compatibility.
  • Voice assistant: Decide which assistant you prefer — Google Assistant, Alexa, or Bixby (Samsung). Some TVs support multiple.
  • Thread border router: If you plan to use Thread devices (like many Matter sensors), the TV must have a Thread radio. Not all do, so check the spec sheet.
  • Operating system: Google TV and Samsung Tizen have the most mature smart home integrations. Roku is simpler but less flexible.
  • Ethernet port: A wired connection is more reliable than Wi-Fi for a hub, especially if you have many devices.

Remember that the TV’s hub functionality is secondary to its picture quality. Don’t sacrifice a good panel for a slightly better smart home feature set — you can always buy a dedicated hub later.

Common Problems and How to Fix Them

TV hubs aren’t perfect. Here are typical issues and solutions:

  • Devices not discovered: Make sure the TV and the device are on the same Wi-Fi network (including the same band — 2.4GHz vs 5GHz). Some devices only work on 2.4GHz.
  • Voice commands not working: Check that the microphone is enabled and that the correct assistant is set as default. Also ensure the TV is not in “privacy mode” that disables mics.
  • Hub disconnects after TV sleeps: Some TVs turn off Wi-Fi when in standby to save power. Look for a setting like “Keep Wi-Fi on during standby” or “Network standby” and enable it.
  • Matter devices not pairing: Try restarting the TV and the device. Also, ensure the TV’s firmware is up to date, as Matter support is often added via updates.
  • Latency: Voice commands may take a second or two longer than a dedicated speaker. This is normal; the TV is processing more data.

Security and Privacy Considerations

Having a TV as a hub means it’s always listening (if you enable far-field mics) and always connected. Here are key points:

  • Microphone privacy: Most TVs have a physical switch or a setting to disable the mic. Use it when you don’t need voice control.
  • Network security: Keep your TV firmware updated to patch vulnerabilities. Don’t use the same password for your TV account as for your email.
  • Data collection: Smart TVs collect viewing data and voice commands. Review the privacy settings to limit what’s shared.
  • Local vs cloud: Matter supports local control, meaning commands don’t have to go to the cloud. Prefer devices that support local operation for faster response and better privacy.

Alternatives to a TV Hub

If your TV lacks hub features, or you want more robust control, consider these alternatives:

  • Smart speakers: Amazon Echo or Google Nest speakers are dedicated hubs with better microphones and support for more protocols (including Zigbee in some models).
  • Dedicated hub hardware: Devices like the Hubitat or Home Assistant (on a Raspberry Pi) offer advanced automation without cloud dependency.
  • Use your phone: Most smart home apps turn your phone into a remote control, though it’s not a hands-free hub.
  • Streaming stick with hub: Some streaming devices (like the Amazon Fire TV Cube) have built-in smart home hubs and can be plugged into any TV.

Ultimately, the best setup often combines a TV hub for visual control and a smart speaker for voice — they complement each other.

Frequently Asked Questions

Do all smart TVs work as smart home hubs?

No. Only TVs that explicitly support Matter or have a built-in smart home controller (like Samsung SmartThings or Google Home) can act as hubs. Many budget TVs only support streaming and have no hub functionality.

Can my TV control lights without a separate hub?

Yes, if the lights are Wi-Fi or Matter-compatible and the TV supports those protocols. You’ll need to pair them through the TV’s smart home app. For Zigbee/Z-Wave lights, you’ll need a separate hub.

Does the TV need to be on to control devices?

No, most TVs with hub functionality can process commands in standby mode as long as they’re plugged in and have network standby enabled. However, some TVs may wake up briefly, which can be annoying if you’re trying to sleep.

Will a TV hub work with Apple HomeKit?

Some TVs support HomeKit via Matter, but it’s not universal. Check if the TV is certified for “Works with Apple HomeKit.” If not, you can bridge it using a HomeKit-compatible hub.

Is it safe to leave my TV in standby mode all the time?

Yes, modern TVs are designed for that. They consume very little power (typically 0.5–3 watts) in standby. However, if you’re concerned about energy, you can turn off the network standby feature, but then you lose hub functionality.
