4 Ways to Transform Your Older Smart TV Into a Home Automation Hub

If you have an aging smart TV gathering dust in a bedroom or spare room, don’t rush to replace it. Many older models can be repurposed into a central control point for your entire home automation system. With the right approach, that outdated display becomes a functional centerpiece for managing lights, sensors, thermostats, and other connected devices throughout your home.

Display Home Assistant Dashboards Through Your TV’s Built-in Browser

Most smart televisions include a web browser, even if they haven’t received software updates in years. While these browsers may struggle with modern, feature-heavy websites, they handle simple locally-hosted dashboards remarkably well. If you use Home Assistant for your automation system, you can create a custom dashboard and direct your TV’s browser to display it continuously.

This approach works best when you design your dashboard with a TV display in mind. Keep the interface clean and straightforward, avoiding complex interactive elements unless you’re willing to connect a keyboard and mouse to your television. The beauty of this method is its simplicity: once configured, your dashboard runs on your TV without requiring additional hardware or ongoing adjustments.

Cast Your Dashboards Wirelessly Using Chromecast Technology

If your TV has Chromecast built in, or if you own a Chromecast device, you unlock a more flexible option. Home Assistant Cast allows you to push your automation dashboards to your television screen wirelessly, eliminating the need to rely on your TV’s aging browser or internal apps. This is particularly valuable since many older smart TVs have sluggish processors and unreliable software that can cause display issues.

The wireless casting approach includes automation capabilities, meaning you can schedule dashboards to appear on your TV at specific times without manual intervention. Keep in mind that some advanced features do have limitations: custom dashboard cards may not display correctly, and live video streams aren’t currently supported through Home Assistant Cast. However, for most home automation displays, these restrictions won’t impact your setup. The best 4K webcams for streaming might complement your system if you want to add camera feeds through other methods.

Install Dedicated Home Automation Apps on Android TV or Google TV

If your older TV runs Android TV or Google TV, you can download specialized apps designed for home automation control. HA TV Dashboard, for example, was built specifically for television-sized displays and formats its interface to match the viewing distance and control scheme of a living room setup.

This method shines when you need to display multiple live video streams simultaneously, something the browser and casting approaches struggle with. If your current TV doesn’t have Google Play store access, the solution is straightforward: purchase an inexpensive Android TV streaming device or stick and connect it via HDMI. Used options cost very little and expand your TV’s capabilities without requiring you to upgrade the television itself. Portable power solutions can keep these smaller streaming devices running if you position them away from wall outlets.

Mount a Raspberry Pi Behind Your TV for Maximum Flexibility

For users comfortable with technical configurations, mounting a Raspberry Pi behind your television offers the most customizable solution. This single-board computer can run Home Assistant directly while simultaneously outputting dashboards to your TV through an HDMI connection. Unlike typical Home Assistant setups that operate headlessly on a network, the HAOS-kiosk project enables you to interact with your automation system using a mouse and keyboard connected to the same device running the software.

This approach removes the limitations of browser compatibility and casting protocols entirely. You gain the full power of a Linux-based system capable of running multiple smart home services simultaneously. The Raspberry Pi remains hidden behind the TV, creating a clean appearance while providing genuine computing capability. You can build elaborate custom dashboards, display information from various sources, and even expand functionality beyond basic home automation.

Different Raspberry Pi models offer varying performance levels, so your choice depends on how many services and dashboards you plan to run. Even the more affordable models provide sufficient power for most home automation scenarios. Smart rings for sleep tracking represent another category of connected devices that integrate seamlessly with Home Assistant systems built on Raspberry Pi hardware.

Choosing Your Approach

Each method works in different circumstances. Browser-based dashboards suit users who want zero additional hardware investment. Chromecast casting balances simplicity with wireless flexibility. Android TV apps provide the best experience for systems requiring live video displays. Raspberry Pi solutions appeal to advanced users seeking unlimited customization and integration possibilities.

Your choice depends on your technical comfort level, the specific capabilities of your current TV, and what features matter most for your home automation setup. Regardless of which option you select, your aging television transforms from an obsolete device into an active participant in your smart home ecosystem.
