Summary
$69 Home Assistant Connect AUX-2 is now on sale worldwide, letting users bring older speakers, TVs and other gear into Home Assistant instead of replacing them.
The compact hub streams music through analog or optical output, supports lossless CD-quality playback via Music Assistant, and can group legacy hi-fi systems with compatible smart speakers for multi-room audio.
Two RS-232 ports let it control compatible TVs and AV receivers locally—even with a smart TV disconnected from the internet—while Bluetooth proxy support extends nearby smart-home device connectivity.
PoE support allows power and networking over one Ethernet cable, but the device needs Home Assistant 2026.9 or later, ESPHome integration, supported hardware, and in some cases extra cables or adapters.
