Home Assistant Connect AUX-2: the smart home multi-tool
With Home Assistant Connect AUX-2, you can bring the devices you already own into your smart home. Stream CD-quality audio directly to your Hi-Fi system or AV amplifier, perfectly synchronized with the smart speakers in your home. Manage photovoltaic systems, TVs, UPSs, and much more via the USB port and two serial ports. Relocate your Z-Wave network to the best spot in the house and extend Bluetooth coverage with a dedicated antenna. Power over Ethernet (PoE) lets you install it cleanly with a single cable, with Wi-Fi and USB-C power ready when you need them. And every purchase helps fund the development of Home Assistant.
⚠️ Please note before purchasing

What you can do with Connect AUX-2
- Breathe new life into your old audio system: connect a stereo, amplifier, or active speakers to the 3.5 mm jack or optical S/PDIF output and play music in sync with other speakers in your home via Music Assistant (Sendspin).
- Control serial devices: TVs, amplifiers, projectors, and other devices with an RS-232 port; with the Waveshare USB-RS485 adapter, you can also control photovoltaic inverters, battery storage systems, UPSs, and other RS-485 devices.
- Optimize your Z-Wave network: connect a Connect ZWA-2 to the USB-A port and place it where coverage is best, even far from your Home Assistant server: all you need is a network cable.
- Extend Bluetooth: acts as a Bluetooth proxy for Home Assistant, with up to 3 active connections.
- Coming soon: Zigbee via PoE with Connect ZBT-2. Nabu Casa is about to release Zigbee via PoE support, starting with the Connect ZBT-2 connected to the USB-A port. It will be an initial experimental version, available with Home Assistant 2026.11 and the latest AUX-2 firmware: for now, Nabu Casa recommends not using it on your home's main Zigbee network.
