Nabu Casa launches Home Assistant Connect AUX-2 worldwide for $69 / €59. The small box connects existing audio equipment, compatible serial devices and Bluetooth devices to the open home. One Ethernet cable can supply both its network connection and power; USB power and Wi-Fi are alternatives.
For an older hi-fi, AUX-2 supplies analog or optical digital audio through Music Assistant and Sendspin. A compatible amplifier’s serial connection can also control its volume, source and power. Two serial ports connect equipment such as televisions and climate systems, provided Home Assistant supports the device and the right cable is used.
AUX-2 also acts as a Bluetooth proxy and lets a USB-connected Z-Wave adapter sit somewhere with better coverage than the Home Assistant computer. In the launch post, Nabu Casa product manager Shay Redmond recommends a wired connection. Zigbee-over-network support is still being tested, and Thread is not supported over this connection.
The hardware is unlocked for custom firmware, and a Grove port accepts additional sensors with an ESPHome configuration. Four screws provide access to the inside; Nabu Casa says it will also publish the circuit-board and 3D-print files.
