Recently i managed to change a file in the Home Assistant configuration and then i forgot about that change… a bit later i started the upgrade to the latest version of Home Assistant which doesn’t check if Home Assitant could be started with the current configuration … of course i had managed to break it and so home assistant “core” didn’t start. The solution was to logon either via SSH (if you have the addon installed and configured) or to have access to the console of the Home Assistant OS. Once you are logged on, follow these steps:

  • Enter login to switch from the ha tool to the commandline
  • Change to the home assistant directory via cd /mnt/data/supervisor/homeassistant
  • Edit the corresponding file via vi <filename>
  • Enter exit to go back to the ha tool.
  • Enter core restart to restart home assistant

Hopefully it should be able to start again :)
