Not every device needs replacing just because it missed the smart home revolution. That old stereo gathering dust might still sound better than your shiny new wireless speaker, while your TV or heating system could be perfectly capable of following commands without an internet connection. Home Assistant wants to bridge that gap with a new accessory that gives yesterday’s technology a place in today’s connected home.

The new Home Assistant Connect AUX-2 is a multi-purpose accessory from Nabu Casa, the company behind official Home Assistant hardware. Rather than adding yet another gadget to your home, Connect AUX-2 is designed to make better use of the ones you already own, bringing older audio systems, TVs, solar equipment, and more into an existing Home Assistant setup.

Music lovers have plenty to gain here. AUX-2 can stream lossless audio to compatible older amplifiers and receivers. Pair it with the free Music Assistant software, and that forgotten hi-fi can play music from Spotify, Tidal, or local files. You can even sync it with compatible modern speakers, including Sonos and Apple’s HomePod, for music throughout the house. Supported older equipment can also have its volume, input source, and power controlled through Home Assistant.

But the music doesn’t stop at speakers. Connect AUX-2 can also connect to compatible TVs, projectors, heating systems, solar inverters, and battery equipment, allowing them to communicate directly with Home Assistant without relying on manufacturer apps or cloud services.

For TVs, that could be particularly useful. AUX-2 lets you control compatible models locally, meaning you could disconnect your TV from the internet to limit data collection without giving up basic controls. You would, however, lose internet-dependent features such as built-in streaming apps.

Beyond older electronics, AUX-2 can serve as a Bluetooth hub for nearby smart devices. It also lets you connect Home Assistant’s separate Z-Wave adapter over the network, giving you more freedom to position it for better coverage.

Installation is flexible, too. The device supports Power over Ethernet or USB-C power and Wi-Fi, while automatic discovery and a setup wizard simplify getting started. It also runs open-source software, and Nabu Casa plans to release its circuit board design and 3D-print files for enthusiasts.

For anyone with a collection of perfectly good electronics that never learned the language of modern smart homes, AUX-2 offers a way to bring them into the conversation without sending them to the recycling pile.

Home Assistant Connect AUX-2 is available starting November 11, priced at $69 in the US and €59 in Europe.
