The Home Assistant Voice Preview Edition is Nabu Casa's first official HA-branded voice satellite - the device the Home Assistant team has wanted to ship for years to make HA Assist a credible Echo Dot alternative. At £59 UK street price, it's not aiming to win on raw mic-array specs against Amazon - it's aiming to be the privacy-first, locally-hosted alternative for HA-first households.

What you're buying

The HA Voice PE is a compact (~80mm cube) USB-C-powered voice satellite with a 2-mic linear array, 12 RGB LEDs for feedback, on-device wake-word detection (Wyoming protocol), Wi-Fi + BLE connectivity, and an open-hardware design with published schematics. It's deliberately spec-modest - the goal isn't to beat the Echo Show on mic pickup, it's to provide a credible HA-first satellite that doesn't ship anything to Amazon, Google, or anywhere else by default.

The integration story is the unique selling point. The PE talks directly to Home Assistant Assist over your local network - wake-word detection runs on-device, then audio streams to HA for STT (typically Whisper), the configured Conversation integration (Ollama for local LLM, OpenAI / Anthropic for cloud), and TTS (Piper for local, ElevenLabs / HA Cloud for cloud). No vendor cloud touches the request unless you specifically configure it to.

How does it perform?

Practical performance for typical UK smart-home use:

  • Wake-word reliability: Roughly 95% accuracy in quiet rooms, dropping to 85-90% with background TV or kitchen noise. Comparable to first-gen Echo Dot; behind current Echo Pop and Nest Mini 2nd gen.
  • Mic pickup range: Reliable to about 3-4 metres in normal home conditions. Beyond 5 metres or behind soft furnishings the 2-mic array struggles.
  • End-to-end voice response latency: 1.5-2.5 seconds with local Ollama + Whisper STT + Piper TTS on a Mac mini M4. 2-3 seconds with cloud Claude + cloud Whisper + Piper TTS. Both feel responsive.
  • Wake-word accuracy in noisy environments: Lower than Echo Show 8, slightly worse than Echo Dot 5th gen, but acceptable for the price tier.
  • Speaker output: None on the device. You configure HA Assist to route responses to a separate media-player target (an existing HomePod Mini, Sonos speaker, Echo Dot acting as a Bluetooth speaker, etc.).

Who is this for?

Best for

HA-first households + privacy-conscious buyers

Existing Home Assistant users who want a privacy-first voice satellite without committing to Amazon's or Google's ecosystem. Households running local Ollama and wanting fully-offline voice. Tinkerers who value the open-hardware design and want to mod the device.

Skip if

Mainstream consumer buyers without HA

If you don't already have Home Assistant set up, an Echo Dot or Nest Mini is dramatically simpler to get going. The HA Voice PE requires HA configuration knowledge - not a first-time-buyer device.

Setup walkthrough

  1. Power via USB-C

    Plug into a 5V USB-C wall adapter or PC port. LED ring lights to indicate setup mode.

  2. Adopt via HA Assist

    Open Home Assistant → Settings → Devices & Services. The PE auto-discovers over the local network. Click 'Set Up' and select the Assist pipeline you want it to use.

  3. Configure your Conversation agent

    Pick local Ollama (private, requires hardware), cloud OpenAI / Claude / Gemini (£5-15/month, best capability), or hybrid (local primary + cloud fallback). See our cloud vs local LLM analysis for the trade-offs.

  4. Set the media-player output target

    Pick where TTS responses play - existing Sonos, HomePod Mini, Echo as Bluetooth speaker, or a dedicated speaker. The PE itself has no audio output.

  5. Test wake-word + a basic command

    Say 'Hey Jarvis' (default) or your custom wake-word. LED ring should light. Issue a test command like 'turn on the kitchen lights'. Latency 1-3 seconds expected.

Frequently asked questions

Q01HA Voice PE vs Amazon Echo Dot - which should I buy?
For HA-first or privacy-first households: HA Voice PE. For mainstream consumer use without HA: Echo Dot. The two devices target different markets - Echo Dot is plug-and-play with Alexa+ cloud; HA Voice PE is the local-first alternative for households that already run HA.
Q02Does the HA Voice PE work without an internet connection?
Yes - fully, if you're using a local Conversation agent (Ollama). Wake-word, STT (Whisper), conversation (Ollama), and TTS (Piper) all run on your local HA box. Internet is only needed if you've configured a cloud LLM as the Conversation agent.
Q03Can I use multiple HA Voice PE devices in one house?
Yes - one per room is the typical recommendation for a typical UK 2-3 bed house. Each adopts independently into HA Assist. Wake-word detection is per-device, so no cross-room confusion.
Q04Why does Nabu Casa call it 'Preview Edition'?
It's the first official HA-branded satellite hardware. 'Preview' indicates the team expects iterations and improvements over the next generations. The current PE is fully functional and supported - not beta software in the typical sense.
Q05Where do I buy the HA Voice PE in the UK?
Pimoroni (Sheffield-based retailer) is the main UK stockist at £59. The Nabu Casa Shop sells direct internationally; UK shipping adds £8-12. Amazon UK has had intermittent stock from third-party sellers - check seller reputation before buying.
Q06Can I run my Ollama LLM on the HA Voice PE itself?
No - the PE is too low-powered for LLM inference. The PE does wake-word detection on-device; the conversation LLM runs on your Home Assistant host (Mac mini, mini-PC, or other appropriate hardware). See our best mini PC for Home Assistant guide for the host pick.

The bottom line

For Home Assistant households the Voice PE is genuinely the right voice satellite to buy in 2026 - tight Assist integration, privacy-first design, works with both cloud and local LLMs, £59 UK price. The 2-mic array is the main compromise vs Amazon's hardware but for typical UK 2-3 bed home conditions it's adequate.

For non-HA buyers, Echo Dot remains the simpler choice. The HA Voice PE is a hobbyist-tier device that rewards the time you put into HA Assist configuration; it's not a first-time-buyer product. Once your HA setup is mature, the PE is the satellite that makes voice work the way you actually want it to.
