Repurposing old hardware can breathe new life into devices that might otherwise be discarded. An old Android tablet, for instance, can be transformed into a functional Home Assistant control panel, serving as both a monitoring dashboard and a voice control interface.
Setting Up the Control Panel
To begin, the Home Assistant Companion App is essential for creating this makeshift control panel. It provides the necessary tools to manage smart home devices effectively. However, maintaining battery health is crucial, as keeping the tablet plugged in continuously can lead to battery swelling and potential hazards.
To mitigate this, a smart plug can be used in conjunction with automation rules. The automation monitors the tablet’s battery level, powering off the smart plug when the battery reaches 80% and turning it back on when it drops below 10%. This setup allows for safe operation while keeping the tablet functional.
Optimizing the User Interface
While the tablet’s larger screen is advantageous for managing smart home dashboards, the original desktop-oriented designs can be cumbersome. The Bubble Card integration within Home Assistant addresses this issue by allowing users to group related devices under single headers. When tapped, these headers open pop-up windows that provide controls for each device, streamlining the user experience.
Although configuring the visual elements in Bubble Card may take time, it significantly enhances the usability of the tablet as a control panel.
Voice Control Capabilities
The tablet can also function as a voice assistant, thanks to the recent addition of wake word detection in the Home Assistant Companion App. This feature enables the tablet to recognize activation phrases, triggering the Assist functionality without manual input.
For a more advanced setup, the tablet can be connected to AI models hosted on local servers, allowing for a fully functional voice assistant. Utilizing models like Gemma-4-26B-A4B for conversation and faster-whisper for speech recognition enhances the tablet’s capabilities, making it a reliable smart home control panel.
Alternative Uses for Old Tablets
If Home Assistant is not your preference, there are various other projects for repurposing an old Android tablet. It can serve as a dedicated touchscreen monitor for security camera feeds or be transformed into an eBook reader using specific applications. Additionally, using tools like Termux allows for running various distributions and open-source applications directly on the tablet.
