Product angle
The Aux-2 is presented as a smart home multi-tool that enhances Home Assistant’s capabilities by bridging different communication protocols and connecting otherwise incompatible devices. Its versatility allows integration of Bluetooth devices, legacy AV equipment, and sensors through serial ports and specialized connectors. The device builds on Home Assistant’s open-source foundation, using ESPHome firmware to enable customized and flexible smart home setups. The Verge’s hands-on review highlights how the Aux-2 addresses practical challenges in everyday smart home use through straightforward setup and broad connectivity.
This new hardware is part of Nabu Casa's ongoing effort to make Home Assistant more accessible and powerful for a wider range of users. The Aux-2’s ease of installation and configuration, via web and Home Assistant’s interface, lowers barriers for those who have mixed ecosystems or technical hurdles in smart home environments. These traits position it as a utility device poised to fill gaps between new smart devices and legacy equipment, thus extending the life and function of existing household technology.
Best for / avoid if
The Connect Aux-2 is best suited for smart home enthusiasts and DIY users who have a diverse array of older or non-IP smart devices that need to interface with Home Assistant. It's particularly helpful for those wanting to incorporate Bluetooth sensor data or control devices via serial connections without extensive rewiring or purchasing entirely new smart appliances. Users interested in open-source solutions and customization will also benefit from its ESPHome-based firmware and modular design.
Conversely, it may be less ideal for those relying exclusively on fully integrated ecosystems like Apple HomeKit or Google Home without using Home Assistant, since the device is focused on expanding Home Assistant’s feature set. Users without some existing technical familiarity or willingness to navigate setup via the Home Assistant platform might find the multi-step configuration process challenging, though it is made easier by the provided setup tools.
Pricing and alternatives to check
The Home Assistant Connect Aux-2 is priced at $69, which positions it as an affordable add-on for expanding smart home device compatibility without investing in multiple standalone hubs or replacement equipment. This cost includes hardware supporting Wi-Fi, Bluetooth, serial, and audio connections in a compact design tailored specifically for integration with Home Assistant installations.
Potential alternatives include purchasing dedicated smart hubs focused on Zigbee or Z-Wave connectivity, Bluetooth bridges from third-party vendors, or smart amplifiers for audio streaming. However, none may provide the same comprehensive multi-protocol bridging combined into a single device that leverages Home Assistant’s open framework. Prospective buyers might also compare solutions from other DIY platforms but should consider the ease of integration and support community that Home Assistant offers.
