The open source, privacy-focused voice assistant, built to work with Home Assistant

Home Assistant Voice Preview Edition is the open source, privacy-focused voice assistant built to seamlessly connect with Home Assistant, and preview the future of voice today. Its advanced audio processor and dual microphones allow it to hear your commands and control devices. Tactile controls, the injection-molded case and LED ring lend to its premium feel, allowing it to blend into the home.

Note: Voice Preview Edition requires Home Assistant to operate. Lower-performance Home Assistant hardware may result in slower speech processing. For optimal performance, we recommend offloading speech processing to Home Assistant Cloud if your hardware is less powerful. If you are experiencing issues please try to upgrade to the latest firmware by connecting your HA Voice PE to a computer via USB-C and using this tool "https://esphome.github.io/home-assistant-voice-pe/".

Great service & delivery as specified

Have yet to install & active my speaker but service to this point has been outstanding.

Great fast shipping

Great way to get started with Music Assistant

I have 3 of these connected to 3 different stereo systems and am using them to stream my music collection (all FLAC files) throughout the house using Music Assistant. The SendSpin protocol is working extremely well for me, allowing for synchronization of streams between players in different rooms.

This was the easiest way to get good quality audio support for Music Assistant since I didn't have any of the other supported players.

Very easy to onboard using my existing Home Assistant setup.

Highly recommend if you want to get started with Music Assistant.

Works as advertised

Easy to setup. Works well. Not Alexa but local option makes it appealing

Needs allot of polishing.

I finally after several hours of troubleshooting with the help of several AI's have this thing "working". The incredibly clunky setup process which caused a cascade of problems in my Home Assistant Green installation was problematic enough. The few commands I have given it have resulted in some comical misunderstandings. For example it will turn the lights on in one room then it will turn the lights off in another. I want to use my own wake word but cant stomach any more configuration in Home Assistant which is also proving to be allot less polished than I had hoped. I'm not giving this 1 star only because I assume that for some this can work great after enough effort. At earlier stages in my life I would have loved the challenge but I have other projects that need my attention and don't want to spend days messing around with this thing. I'm also frustrated to find that to really get the most of this I need to sign up for an HA cloud account for cloud voice processing. I came to HA because I didn't want cloud connected microphones spread through my house and I wanted true off the grid functionality. I didn't even know this was a "preview" product prior to purchase and wish its limitations had been made more clear to me. Right now I give myself a 25% chance of finding the time and motivation to get this working to anywhere near my original expectations of it.

Hi Ryan,

We're really sorry to hear about the frustrating experience you've had getting the Home Assistant Voice Preview Edition set up and running smoothly on your Home Assistant Green. We completely understand how time-consuming and discouraging troubleshooting can be, especially when you're juggling other projects and just want reliable voice control without cloud dependencies.

As far as I understand The 'Preview Edition' label refers to this being an early hardware release to help accelerate community-driven development of open-source voice features—it's not a reflection on the core functionality being incomplete, but rather that the hardware (mics, audio processing, etc.) and overall voice ecosystem are still evolving rapidly with community input. That said, your feedback about clearer upfront communication on limitations and setup complexity is valuable, we believe our product page has notes about these situations.

Regarding fully local (off-grid) operation: You're absolutely right that Home Assistant's strength is privacy-focused, local control, and you do not need Home Assistant Cloud for voice processing. However, advanced local speech-to-text (STT) and intent recognition can be resource-intensive. The Home Assistant Green is great for core automation but may experience slower processing or misunderstandings with demanding local voice pipelines (like Whisper for STT). Official recommendations suggest an Intel N100-based system (or higher) for the smoothest fully local experience (which is noted in the product description).

Some options to improve performance without cloud:

Offload voice processing to separate, more powerful local hardware: Run the heavier components (e.g., faster Whisper models or even a local LLM for smarter intent handling) on a mini-PC, old laptop, or dedicated server on your network. This keeps everything 100% local and offline while giving much faster, more accurate responses, I have been able to get my HA Voice PE to work without issues and run a small LLM using Ollama from my laptop using docker.

Run Home Assistant on a more Powerful hardware, Nabu Casa recommends a N100 or better CPU, we have tested using N97 or even with the Raspberry Pi CM5 on the HA Yellow and voice processing works without any issues.

If you'd like help troubleshooting your specific setup (e.g., pipeline recommendations or entity exposure tips), feel free to share more details or head over to the Home Assistant community forums—lots of users have overcome similar hurdles.

Thanks for giving it a shot and for the honest feedback. We hope you'll find the time to tweak it further—many users end up loving the privacy and flexibility once dialed in.

Best regards,
Brandon
