• Built for Home Assistant: The first voice hardware designed by the team driving the development of Home Assistant, and built from the ground up to work with Home Assistant. 
• Preview the future of voice today: Home Assistant is rapidly advancing their open source, privacy-focused voice assistant for the home. Preview Edition was built to help more people participate in development and allow anyone to preview the future of voice today.
• The easiest way to start with Assist: Just connect it to USB-C power (cable and power supply not included) and it will connect with Home Assistant via an intuitive installation wizard. No assembly required. 
• The private voice assistant: Pairing Voice Preview Edition with powerful Home Assistant hardware can allow it to run fully locally, or offload its audio processing to the privacy-focused Home Assistant Cloud - Home Assistant. It also includes a hardware mute switch that physically cuts power to the microphones.
• Language support: Assist aims to support more languages than other voice assistants, but this is still a work in progress, and Home Assistant needs your help. Check the Talking with Home Assistant - get your system up & running - Home Assistant in the Home Assistant’s Assist documentation.
• Advanced Audio Processing: Dual microphones and the XMOS audio processor cuts through noise to hear your voice clearly.
• Visual and audio feedback: The multicolored LED ring displays when it's listening, volume levels, and more. Get sensor readings, timers and other feedback via its speaker. Connect an external speaker for media playback via its 3.5mm headphone jack.
• Physical controls: The rotary dial lets you control volume and LED brightness, while the multifunction button can trigger Assist or be customized in Home Assistant.
• Blends into the home: Its small, unobtrusive design is injection-molded giving it a premium look, and its tactile controls give it a premium feel.
• Expandable: Built on ESPHome, sensors can be added via the included Grove port.
• Fully open and community-driven: Completely open software, firmware, and hardware lets you make it work the way you want.  All backed by a dedicated community customizing and adding functionality.

Fully open and customizable

We tried to make every aspect of Voice Preview Edition customizable, which is actually pretty easy when you’re working hand-in-hand with ESPHome and Home Assistant. It works great with the stock settings, but if you’re so inclined, you can customize the Assist software, ESP32 firmware, and XMOS firmware.

We also made the hardware easy to modify, inside and out. For instance, the included speaker is for alerts and voice prompts, but if you want to use it as a media player, connect a speaker to the included 3.5mm headphone jack and control it with software like Music Assistant. The included DAC is very clean and capable of streaming lossless audio. It can also be used as a very capable ESP32 device. On the bottom of the device is a Grove port (concealed under a cover that can be permanently removed), which allows you to connect a large ecosystem of sensors and accessories.

We’ve also made it quite painless to open, with easy-to-access screws and no clips. We even included exposed pads on the circuit board to make modifying it more straightforward. We’re providing all the 3D files so you can print your own components.
