Community Hass.io Add-ons: Node-RED

Flow-based programming for the Internet of Things.

About

Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.

It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single click.

Installation

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 "Node-RED" add-on.
Set a credential_secret, which is used to encrypt sensitive data. This is just a "password", which you should save in a secondary location.
Start the "Node-RED" add-on.
Check the logs of "Node-RED" to see if everything went well.
Click on the "OPEN WEB UI" button to jump into Node-RED.
The add-on works straight out the box! No need to configure a server!

Note: The add-on is pre-configured out of the box! There is no need to add/change/update the server connection settings!

Please read the rest of this document further instructions.

NOTE: Do not add this repository to Hass.io, please use: https://github.com/hassio-addons/repository.

Configuration

Note: Remember to restart the add-on when the configuration is changed.

Example add-on configuration:

{
  "log_level": "info",
  "credential_secret": "KJHhfdhiFRENCKfsdfdsDHFHDJS",
  "http_node": {
    "username": "MarryPoppins",
    "password": "Supercalifragilisticexpialidocious"
  },
  "http_static": {
    "username": "MarryPoppins",
    "password": "Supercalifragilisticexpialidocious"
  },
  "ssl": true,
  "certfile": "fullchain.pem",
  "keyfile": "privkey.pem",
  "require_ssl": true,
  "system_packages": [
    "ffmpeg"
  ],
  "npm_packages": [
    "node-red-admin"
  ],
  "init_commands": [
    "echo 'This is a test'",
    "echo 'So is this...'"
  ]
}

Note: This is just an example, don't copy and paste it! Create your own!

Option: `log_level`

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.

Option: `ssl`

Enables/Disables SSL (HTTPS) on the web interface. 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.

Option: `certfile`

The certificate file to use for SSL.

Note: The file MUST be stored in /ssl/, which is the default for Hass.io

Option: `keyfile`

The private key file to use for SSL.

Note: The file MUST be stored in /ssl/, which is the default for Hass.io

Option: `require_ssl`

This option can be used to cause insecure HTTP connections to be redirected to HTTPS. This is recommended when you have SSL enabled.

Option: `credential_secret`

Credentials are encrypted by Node-RED in storage, using a secret key. This option allows you to specify your secret key. This can be anything you like, it is just like a password. Be sure to store it somewhere safe. You might need it in the future! (e.g., When restoring a backup).

Note: Once you set this property, do not change it - doing so will prevent Node-RED from being able to decrypt your existing credentials and they will be lost.

Note: This option support secrets, e.g., !secret red_secret.

Option: `dark_mode`

When set to true, the Midnight Node-RED theme by Mauricio Bonani will be enabled. For more information and a glance at how it looks, see the GitHub repository of this theme:

https://github.com/bonanitech/node-red-contrib-theme-midnight-red

Option: `http_node`

To password protect the node-defined HTTP endpoints (httpNodeRoot), the following properties can be used:

username
password

Note: These options support secrets, e.g., !secret red_password.

Note: In order to use the http_node you will need to expose Node-RED using a network port in addition to ingress. The HTTP nodes will also be presented under /endpoint/ as shown in the UI. If using the node-red-dashboard module this will also be hosted under this path and will use any credentials set here.

Option: `http_static`

To password protect the static content (httpStatic), the following properties can be used:

username
password

Note: These options support secrets, e.g., !secret red_password.

Option: `system_packages`

Allows you to specify additional Alpine packages to be installed to your Node-RED setup (e.g., g++. make, ffmpeg).

Note: Adding many packages will result in a longer start-up time for the add-on.

Option: `npm_packages`

Allows you to specify additional NPM packages or Node-RED nodes to be installed to your Node-RED setup (e.g., node-red-dashboard, node-red-contrib-ccu).

Note: Adding many packages will result in a longer start-up time for the add-on.

Option: `init_commands`

Customize your Node-RED 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.

Option: `i_like_to_be_pwned`

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!

Option: `leave_front_door_open`

Adding this option to the add-on configuration allows you to disable authentication on the add-on 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!

Known issues and limitations

While this add-on ships with Node-RED Dashboard, it currently does not support accessing the dashboard via Hass.io Ingress. This is a technical limitation on the Node-RED Dashboard end.
Node-RED Dark theme does not play nice with Node-RED Dashboard. Therefore, it is strongly advised to disable dark_mode when using the Node-RED Dashboard.
If you cannot access HTTP nodes or Node-RED Dashboard, please check if you have enabled direct access mode by setting a port number in "Network" configuration section of the add-on.
If you cannot access HTTP nodes or Node-RED Dashboard, please check if you URL starts with /endpoint/, or else Home Assistant authentication will kick in.

Changelog & Releases
