This add-on allows you to log in to your Hass.io Home Assistant instance using SSH or by using the Web Terminal.
This add-on allows you to log in to your Hass.io Home Assistant instance using SSH or a Web Terminal, giving you to access your Hass.io folders and also includes a command-line tool to do things like restart, update, and check your instance.
This is an enhanced version of the provided SSH add-on by Home Assistant and focusses on security, usability, flexibility and also provides access using a web interface.
The SSH & Web Terminal add-on is a really powerful and gives you virtually access to all tools and almost all hardware of your system.
While this add-on is created and maintained with care and with security in mind, in the wrong or inexperienced hands, it could damage your system.
This add-on, of course, provides an SSH server, based on OpenSSH and a web-based Terminal (which can be included in your Home Assistant frontend) as well. Additionally, it comes out of the box with the following:
- Access your command line right from the Home Assistant frontend!
- A secure default configuration of SSH:
- Only allows login by the configured user, even if more users are created.
- Only uses known secure ciphers and algorithms.
- Limits login attempts to hold off brute-force attacks better.
- Many more security tweaks, this addon passes all ssh-audit checks
without warnings!
- Passwords are checked with HaveIBeenPwned using K-anonymity.
- Comes with an SSH compatibility mode option to allow older clients to connect.
- Support for Mosh allowing roaming and supports intermittent connectivity.
- SFTP support is disabled by default but is user configurable.
- Compatible if Hass.io was installed via the generic Linux installer.
- Username is configurable, so
root
is no longer mandatory. - Persists custom SSH client settings & keys between add-on restarts
- Hardware access to your audio, uart/serial devices and GPIO pins.
- Runs with more privileges, allowing you to debug and test more situations.
- Has access to the dbus of the host system.
- Has the option to access the Docker instance running Hass.io host system.
- Runs on host level network, allowing you to open ports or run little daemons.
- Have custom Alpine packages installed on start. This allows you to install your favorite tools, which will be available every single time you log in.
- Execute custom commands on add-on start so that you can customize the shell to your likings.
- ZSH as its default shell. Easier to use for the beginner, more advanced for the more experienced user. It even comes preloaded with "Oh My ZSH", with some plugins enabled as well.
- Contains a sensible set of tools right out of the box: curl, Wget, RSync, GIT, Nmap, Mosquitto client, MariaDB/MySQL client, Awake (“wake on LAN”), Nano, Vim, tmux, and a bunch commonly used networking tools.
- Has the Home Assistant CLI (
hass-cli
) commandline tool pre-installed and pre-configured. - Support executing commands inside using a Home Assistant service call, e.g., for use with automations.
The installation of this add-on is pretty straightforward and not different in comparison to installing any other Hass.io add-on.
- Add our Hass.io add-ons repository to your Hass.io instance.
- Install the "SSH & Web Terminal" add-on.
- Configure the
username
andpassword
/authorized_keys
options. - Start the "SSH & Web Terminal" add-on.
- Check the logs of the "SSH & Web Terminal" add-on to see if everything went well.
NOTE: Do not add this repository to Hass.io, please use:

The log_level
option controls the level of log output by the addon and can
be changed to be more or less verbose, which might be useful when you are
dealing with an unknown issue. Possible values are:
trace
: Show every detail, like all called internal functions.debug
: Shows detailed debug information.info
: Normal (usually) interesting events.warning
: Exceptional occurrences that are not errors.error
: Runtime errors that do not require immediate action.fatal
: Something went terribly wrong. Add-on becomes unusable.
Please note that each level automatically includes log messages from a
more severe level, e.g., debug
also shows info
messages. By default,
the log_level
is set to info
, which is the recommended setting unless
you are troubleshooting.
Using trace
or debug
log levels puts the SSH and Terminal daemons into
debug mode. While SSH is running in debug mode, it will be only able to
accept one single connection at the time.
The following options are for the option group: ssh
. These settings
only apply to the SSH daemon.
This option allows you to change to username the use when you log in via SSH.
It is only utilized for the authentication; you will be the root
user after
you have authenticated. Using root
as the username is possible, but not
recommended.
Note: Due to limitations, you will need to set this option to root
in
order to be able to enable the SFTP capabilities.
Sets the password to log in with. Leaving it empty would disable the possibility to authenticate with a password. We would highly recommend not to use this option from a security point of view.
Note: The password will be checked against HaveIBeenPwned. If it is listed, the add-on will not start.
Add one or more public keys to your SSH server to use with authentication. This is the recommended over setting a password.
Please take a look at the awesome documentation created by GitHub about using public/private key pairs and how to create them.
When set to true
the addon will enable SFTP support on the SSH daemon.
Please only enable it when you plan on using it.
Note: Due to limitations, you will need to set the username to root
in
order to be able to enable the SFTP capabilities.
This SSH add-on focusses on security and has therefore only enabled known
secure encryption methods. However, some older clients do not support these.
Setting this option to true
will enable the original default set of methods,
allowing those clients to connect.
Note: Enabling this option, lowers the security of your SSH server!
Specifies whether ssh-agent forwarding is permitted or not.
Note: Enabling this option, lowers the security of your SSH server! Nevertheless, this warning is debatable.
Specifies whether remote hosts are allowed to connect to ports forwarded for the client.
Note: Enabling this affects all remote forwardings, so think carefully before doing this.
Specifies whether TCP forwarding is permitted or not.
Note: Enabling this option, lowers the security of your SSH server! Nevertheless, this warning is debatable.
The following options are for the option group: web
. These settings
only apply to the Web Terminal.
Enables/Disables SSL (HTTPS) on the web terminal. Set it true
to enable it,
false
otherwise.
Note: The SSL settings only apply to direct access and has no effect on the Hass.io Ingress service.
The certificate file to use for SSL.
Note: The file MUST be stored in /ssl/
, which is default for Hass.io
The private key file to use for SSL.
Note: The file MUST be stored in /ssl/
, which is default for Hass.io
The following options are shared between both the SSH and the Web Terminal.
By default, the terminal session between the web client and SSH is shared. This allows you to pick up where you left your terminal from either of those.
This option allows you to disable this behavior by setting it to false
, which
effectively sets SSH to behave as it used to be.
Allows you to specify additional Alpine packages to be installed in your shell environment (e.g., Python, Joe, Irssi).
Note: Adding many packages will result in a longer start-up time for the add-on.
Customize your shell environment even more with the init_commands
option.
Add one or more shell commands to the list, and they will be executed every
single time this add-on starts.
Adding this option to the add-on configuration allows to you bypass the
HaveIBeenPwned password requirement by setting it to true
.
Note: We STRONGLY suggest picking a stronger/safer password instead of using this option! USE AT YOUR OWN RISK!
Adding this option to the add-on configuration allows you to disable
authentication on the Web Terminal by setting it to true
and leaving the
username and password empty.
Note: We STRONGLY suggest, not to use this, even if this add-on is only exposed to your internal network. USE AT YOUR OWN RISK!
It is possible to embed the Web Terminal directly into Home Assistant, allowing you to access your terminal through the Home Assistant frontend.
Home Assistant provides the panel_iframe
component, for these purposes.
Example configuration:
panel_iframe:
terminal:
title: Terminal
icon: mdi:console
url: https://addres.to.your.hass.io:7681
This add-on uses the hassio.addon_stdin
service to expose a shell interface
to Home Assistant. This allows you to execute commands and scripts within
the SSH & Web Terminal add-on, straight from Home Assistant.
This is particularly helpful when you want to execute custom scripts or commands from automations.
Example automation running my_command
:
automation:
- alias: 'Example my script'
trigger:
platform: state
entity_id: binary_sensor.motion_sensor
to: 'ON'
action:
service: hassio.addon_stdin
data:
addon: a0d7b954_ssh
input: "/config/scripts/my_command"
-
The add-on fails to start when a password that is listed by HaveIBeenPwned is used. This is actually not a limitation, but a security feature.
-
My browser throws an
ERR_SSL_PROTOCOL_ERROR
. The OPEN WEB UI button only works when SSL is enabled. -
When SFTP is enabled, the username MUST be set to
root
. -
The following error may occur in your add-on log, and can be safely ignored:
ERR: lws_context_init_server_ssl: SSL_CTX_load_verify_locations unhappy
