Get root SSH access to the Home Assistant root system remotely (no USB drive needed) ssh into the host system

There are detailed instructions on how to get “root” ssh access to the Home Assistant Operating System but it involves plugging in a USB Drive and importing the SSH keys from that one.

On this page

However: I’m 36 hours away from the system I want root SSH access to! So physical access is just not possible right now, but fear not! there is a solution!

• Install the port 22222 configurator addon
• Configure the addon
• Start the addon
• Done!

Adding a custom repository

and add the following repository

https://github.com/adamoutler/HassOSConfigurator

Now refresh the page you are on (F5 / CMD + R) and locate our new add-ons

Setting up the addon before starting it

before we start the addon we have to configure some things, head over to the configuration of the addon

Put in your public RSA key generated from your private key

(ignore me) personal note:

ssh-keygen -y -f hassio.pem > hassio.pub

Reboot HassOS / Home Assistant Operating System

Reboot your raspberry pi / reboot HassOS

Settings > System > Hardware > Reboot Host

Optional: upload/get your private key on home assistant

now you can SSH into the root system from inside Home Assistant

chmod 400 /config/certs/hassio
ssh -p 22222 -i config/certs/hassio localhost
