Home Assistant's New Gadget Makes Legacy Tech Smart
Nabu Casa's compact new bridge connects vintage hardware to modern smart home ecosystems.

Giving New Life to Legacy Tech
The technology sector is in a constant state of evolution, yet this progress often brings 'planned obsolescence.' Perfectly functional devices frequently become redundant simply because they lack modern smart features or because manufacturers have discontinued cloud service support. To address this, Nabu Casa, the creator of Home Assistant, has launched a new device: the Connect AUX-2.
Priced at $69, this compact unit allows users to bring vintage televisions, stereo systems, and amplifiers into a modern smart home ecosystem. According to Nabu Casa founder Paulus Schoutsen, the most sustainable device is the one you already own. The company's goal is to prevent users from discarding well-functioning hardware just because it is labelled as 'outdated.'
Technical Capabilities and Connectivity
Despite its compact size, the Connect AUX-2 is remarkably versatile. The device features an RS-232 serial port, enabling direct communication with legacy AV receivers and other equipment. This allows you to control older audio systems via a smartphone app or voice commands, without relying on the original manufacturer's servers.
Beyond the RS-232 port, the device supports a wide range of connectivity options, including:
- Bluetooth and Wi-Fi;
- The Z-Wave protocol;
- PoE (Power over Ethernet);
- USB ports for connecting additional adapters.

Users can place multiple AUX-2 devices throughout their home to create a unified, manageable network. For instance, it is possible to integrate an older stereo system into a modern multi-room audio setup, significantly simplifying the control of your home media environment.
Why This Matters
In today's market, smart home systems are often locked into specific manufacturer ecosystems. This Home Assistant initiative moves in the opposite direction by championing openness and integration. For users, this translates into cost savings, as it allows for the expansion of existing hardware functionality rather than requiring the purchase of expensive new 'smart' audio systems.
For users who value high-quality, durable audio equipment and prefer to maintain their hardware, solutions like the Connect AUX-2 offer a compelling path forward. This gadget acts not only as a technological bridge between the past and the future but also as a step toward responsible consumption, helping to reduce electronic waste.
