Free Disk Space

The possible sources of large disk space usage:

  • Backups
  • Home Assistant Database
  • Addons data cache (eg. ESPHome Addon)
  • Media or share (if not network attached storage)

If you are on Home Assistant OS and have access to a shell(eg. using the Terminal&SSH Addon), make sure to run

login

To get full access.

You can first try

du -h -d 1 /

You can play with variations of this, for example

du -ah -d4 / | sort -hr | head -n 20
