This is the OS Agent for Home Assistant. It is used for Home Assistant OS and Home Assistant Supervised installation types and it allows the Home Assistant Supervisor to communicate with the host operating system.

The OS Agent is pre-installed with the Home Assistant Operating System.

Updates are part of the Home Assistant Operating System updates, which the Home Assistant UI will offer to upgrade to when there is a new version available.

Download the latest Debian package from OS Agent GitHub release page at:

https://github.com/home-assistant/os-agent/releases/latest

Next, install (or update) the downloaded Debian package using:

sudo dpkg -i os-agent_1.0.0_linux_x86_64.deb

Note: Replace the deb file in the above example with the file you have downloaded from the releases page.

You can test if the installation was successful by running:

gdbus introspect --system --dest io.hass.os --object-path /io/hass/os

This should not return an error. If you get an object introspection with interface etc. OS Agent is working as expected.

You might need to install libglib2.0-bin to get the gdbus command.

To remove OS Agent from your system use the Debian packaging system:

sudo dpkg -r os-agent

go build -ldflags "-X main.version="

gdbus introspect --system --dest io.hass.os --object-path /io/hass/os
gdbus call --system --dest io.hass.os --object-path /io/hass/os/Boards/Yellow --method org.freedesktop.DBus.Properties.Set io.hass.os.Boards.Yellow PowerLED "<false>"
