Nabu Casa launches Home Assistant Connect Aux-2 smart hub
Nabu Casa has launched the Home Assistant Connect Aux-2, a new multi-function box designed to expand smart home connectivity for users of the Home Assistant platform.
Device specifications and features
The new device is priced at $69 and measures about the size of a deck of cards. It includes 2.4GHz Wi-Fi, Bluetooth, Ethernet, USB-A, USB-C, and digital or analog audio jacks. The box also offers a Grove port for sensors and a pair of RS-232 serial ports. Users can bridge Bluetooth devices into their Home Assistant setup using this new hardware.
Audio and sensor integration
The unit allows users to connect an amplifier or powered speakers to stream music to older audio equipment. Its USB port lets owners plug in a Nabu Casa Z-Wave or Zigbee antenna for better signal range. The serial connector enables control of devices like TVs, AV receivers, and solar inverters via existing integrations.
Development background and context
The Aux-2 utilizes ESPHome, which serves as a free platform for building custom smart home gadgets using adaptable ESP boards. The audio-out feature is powered by Music Assistant and SendSpin, which the team is actively developing right now. The serial integration was developed earlier this year to support specific industrial and home automation needs.
User testing and practical use
Reviewers found the setup process surprisingly easy despite having a Home Assistant install for several years. One tester used the device to track garage fridge temperature after previous sensors frequently dropped connection in Texas heat. The new tool helped finally set up previously unused in-wall speakers without requiring analysis paralysis or complex choices.
