Running a development version

If you want to stay on the bleeding-edge Home Assistant Core development branch, you can upgrade to dev.

{% caution %} The dev branch is likely to be unstable. Potential consequences include loss of data and instance corruption. {% endcaution %}

{% if page.installation == "os" %}

1. Join the dev channel.

   ha supervisor options --channel dev
   

2. Reload the {% term "Home Assistant Supervisor" %}.

   ha supervisor reload
   

3. Update {% term "Home Assistant Core" %} to the latest dev version.

   ha core update --backup
   

   The --backup flag here ensures that you have a partial backup of your current setup incase you need to downgrade.

{% elsif page.installation == "container" %}

docker pull {{ site.installation.container }}:dev

You then need to recreate the container with the new image.
