Run a development version

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

The dev branch is likely to be unstable. Potential consequences include loss of data and instance corruption.

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

1. Join the dev channel

   ha supervisor options --channel dev
   

2. Reload the supervisor

   ha supervisor reload
   

3. Update Home Assistant core to the latest dev version

   ha core update
   

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

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

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

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

1. Stop the Home Assistant service.

2. Switch to the user that is running Home Assistant

   sudo -u homeassistant -H -s
   

3. Activate the virtual environment that Home Assistant is running in

   source /srv/homeassistant/bin/activate
   

4. Download and install the version you want

   pip3 install --upgrade git+https://github.com/home-assistant/core.git@dev
   

5. When that is complete start the service again for it to use the new files.
