System Update Guide for the Lite Xiaozhi AI Voice Speaker

There are two ways to update Xiaozhi: say a few words and let the voice assistant check and upgrade by itself, or open Home Assistant and click update on the device page. Both bring the firmware up to the latest version — pick whichever suits you.

What this guide covers

Check for a new version by voice
Upgrade the system by voice
Update manually in the Home Assistant backend

Check for updates by voice

The Xiaozhi voice assistant can handle updates on its own — no computer needed, just ask. Say the following in order and you can go from “is there an update” all the way to “what actually changed”.

Xiaozhi, is there a new version?

It reports the current version and the latest version.

Xiaozhi, check for updates

Same as the line above; “check for updates” is the shorter way to say it.

What’s new in the update?

Gives a brief summary of what this update changed.

Tell me more

Ask this when you want the details after the summary.

Say these in sequence so it keeps the context — ask “is there a new version” first, then “what’s new”, and finally “tell me more”. Otherwise it will not know which update you mean.

Upgrade the system by voice

Once you know there is a new version and you want it, say the following. Xiaozhi will not start right away — it asks you to confirm first.

Update the system

It first warns you: “The device restarts automatically during the update and the voice assistant goes offline for 1–2 minutes, please wait”, and only starts once you confirm.

Being offline for 1–2 minutes during the update is normal — do not cut the power and do not keep calling it. Once it has restarted, ask “check for updates” again to confirm the version number is the new one.

Update manually in the Home Assistant backend

Use this route when it is inconvenient to talk, or when you want to read the release notes with your own eyes. Everything happens in the Home Assistant web interface.

Open “Settings → Devices & Services”

In the Home Assistant sidebar click Settings at the very bottom, then find and click Devices & Services on the settings page.

Home Assistant settings page with Devices & Services highlighted — Go to “Settings → Devices & Services” and find the **LTCN AI** integration

Open LTCN AI and pick the speaker to upgrade

Under “Devices & Services” find the LTCN AI integration and open it — it lists every AI speaker already connected to this Home Assistant.

Device list under the LTCN AI integration with the white speaker highlighted — Inside LTCN AI, open the AI speaker you want to upgrade — the “white speaker” in this example

Open the one you want to upgrade (the example below is the white speaker) to reach its device page.

Click update under “Configuration” and confirm

The device page has a Configuration column on the right. If Update there shows Update available, click it.

Configuration column on the device page showing Update available — In the **Configuration** column on the right of the device page, click **Update** once it shows “Update available”

The dialog lists the installed version, the latest version and the release notes for this round — click Update at the bottom right to start.

Update dialog listing the installed version, latest version and release notes — The dialog shows what the new version changes — click **Update** at the bottom right to start

If the Update row says Up to date, there is no update available for this speaker right now. Do not close the Home Assistant page while the update runs; just wait for the progress to finish.

Next steps

To try what the new version can do right away, open Common Voice Commands and Feature Guide and read the commands out loud. If this speaker is not connected yet, start with Binding and Setup Guide for Lite Xiaozhi AI Voice Speaker to add it to Home Assistant.
