Autostart using init.d

Home Assistant can run as a daemon within init.d with the script below.

1. Copy script

Copy either the daemon script or the Python environment scrip at the end of this page to /etc/init.d/hass-daemon depending on your installation.

After that, set the script to be executable:

$ sudo chmod +x /etc/init.d/hass-daemon

2. Select a user.

Create or pick a user that the Home Assistant daemon will run under. Update script to set RUN_AS to the username that should be used to execute hass.

3. Change hass executable and other variables if required.

Some installation environments may require a change in the Home Assistant executable hass. Update script to set HASS_BIN to the appropriate hass executable path. Please also check the other variables for the appropriate value. In general the defaults should work

4. Install this service

$ sudo service hass-daemon install

5. Create logrotate rule

This logrotate script at /etc/logrotate.d/homeassistant will create an outage of a few seconds every week at night. If you do not want this add --log-rotate-days 7 to the FLAGS variable in the init script.

/var/log/homeassistant/home-assistant.log
{
        rotate 7
        daily
        missingok
        notifempty
        delaycompress
        compress
        postrotate
                invoke-rc.d hass-daemon restart > /dev/null
        endscript
}

6. Restart Machine

That’s it. Restart your machine and Home Assistant should start automatically.

If HA does not start, check the log file output for errors at /var/log/homeassistant/home-assistant.log

Extra: Running commands before hass executes

If any commands need to run before executing hass (like loading a virtual environment), put them in PRE_EXEC. This command must end with a semicolon.
