- 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. 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 supported languages 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.
