For this to work, you must enable the SSH server add-on and have done a snapshot before making any changes to Home Assistant. While not ideal, it will get you back to a previous working config without

From the Home Assistant GUI –

click on Hass.io

click on Snapshots

Snapshot can be restored from the GUI by clicking on an Available Snapshot

Best practice to do a config check before rebooting

From the Home Assistant GUI –

click on Configuration

click on General

click on Check Config

CLI commands

hassio snapshots list (lists the snapshots available)

core-ssh:~# hassio snapshots list

{

“result”: “ok”,

“data”: {

“snapshots”: [

{

“slug”: “9d170a1e”,

“name”: “12-29 Base Snapshot”,

“date”: “2018-12-29T22:47:26.966864+00:00”,

“type”: “full”,

“protected”: false

}

]

}

core-ssh:~# hassio snapshots restore –slug 9d170a1e

You will loose your SSH session after issuing the command. Home Assistant should come online shortly after that.

Command line option to do a snapshot – hassio snapshots new –name “test”. Replace test with what you want the name of the backup to bee.
