Home-Assistant-Matter-Hub

This project simulates bridges to publish your entities from Home Assistant to any Matter-compatible controller like Alexa, Apple Home or Google Home. Using Matter, those can be connected easily using local communication without the need of port forwarding etc.

1. Installation

This application can be installed in three different ways:

1. Home-Assistant AddOn for Home Assistant OS (preferred)
2. Ready to use Docker Image
3. Manual installation using npm

1.1 Native Home-Assistant AddOn

[!WARNING] Home Assistant AddOns can only be used with Home Assistant OS.

Simply add the following GitHub Repository URL to your Home Assistant AddOn Store.

https://github.com/t0bst4r/home-assistant-addons

1. Open the UI of your Home Assistant instance
2. Go to Settings -> Add-Ons -> Add-On Store
3. Click the three dots in the top-right corner and select Repositories
4. Paste the repository URL into the text-field and click "Add"
5. Refresh your Add-On Store and Install the Add-On
6. You can configure the log level and the port of the Web UI in the AddOn configuration page

1.2 Docker Image

This repository builds a docker image for every release. You can simply pull it with

docker pull ghcr.io/t0bst4r/home-assistant-matter-hub:latest

In the docker image the application stores its data in /data, so you can mount a volume there to persist it, but you could change that by setting the HAMH_STORAGE_LOCATION variable.

Additionally, you have to configure the container as follows:

docker run -d \
  # required: the address of your home assistant instance
  -e HAMH_HOME_ASSISTANT_URL="http://192.168.178.123:8123/" \
  # required: a long lived access token for your home assistant instance
  -e HAMH_HOME_ASSISTANT_ACCESS_TOKEN="eyJ.....dlc" \
  # optional: debug | info | warn | error
  # default: info
  -e HAMH_LOG_LEVEL="info" \
  # optional: the port to use for the web ui
  # default: 8482
  -e HAMH_WEB_PORT=8482 \
  # recommended: persist the configuration and application data
  -v $PWD/home-assistant-matter-hub:/data \
  # required due to restrictions in matter
  --network=host \
  ghcr.io/t0bst4r/home-assistant-matter-hub:latest

1.3 Manual installation using npm

If you want to install this application by hand, you simply need to run

npm install -g home-assistant-matter-hub

To start the application, run

home-assistant-matter-hub start \
  # required: the address of your home assistant instance
  # can be replaced with an environment variable: HAMH_HOME_ASSISTANT_URL
  --home-assistant-url="http://192.168.178.123:8123/" \
  # required: a long lived access token for your home assistant instance
  # can be replaced with an environment variable: HAMH_HOME_ASSISTANT_ACCESS_TOKEN
  --home-assistant-access-token="eyJ.....dlc" \
  # optional: debug | info | warn | error
  # default: info
  # can be replaced with an environment variable: HAMH_LOG_LEVEL
  --log-level=info \
  # optional: the port to use for the web ui
  # default: 8482
  # can be replaced with an environment variable: HAMH_WEB_PORT
  --web-port=8482

The application will store its data in $HOME/.home-assistant-matter-hub. You can configure the storage path by using the --storage-location=/path/to/storage option or HAMH_STORAGE_STORAGE environment variable.

2. Configuration

Due to its advanced configuration options it is not possible to simply configure everything with environment variables or command line parameters. Therefore, bridges are configured within the application itself. General app configuration is done using the CI or environment variables. The following parameters are available:

home-assistant-matter-hub start

start the application

Options:
  --help                         Show help                                                             [boolean]

  --config                       Provide the path to a configuration JSON file, which can include all of the
                                 following options. You can use kebabcase ("log-level") or camelcase ("logLevel").

  --log-level                    Set the log level                                                      [string]
                                 choices: "silly", "debug", "info", "warn", "error"
                                 default: "info"

  --disable-log-colors           Disable colors in the logs (default: false)                           [boolean]

  --storage-location             Path to a directory where the application should store its data.
                                 (default: ~/.home-assistant-matter-hub)                                [string]

  --web-port                     Port used by the web application (default: 8482)                       [number]

  --mdns-network-interface       Limit mDNS to this network interface                                   [string]

  --home-assistant-url           The HTTP-URL of your Home Assistant URL                     [string] [required]

  --home-assistant-access-token  A long-lived access token for your Home Assistant Instance  [string] [required]

Each of those configuration options can be configured via environment variables, too. Simply prefix them with HAMH_ and write them in capslock with underscores (e.g. HAMH_MDNS_NETWORK_INTERFACE).

Those configuration options are not needed for the Home Assistant Addon Installation type.

3. Bridge Configuration

Using the User Interface you can set up multiple bridges and configure each to use different filters for your entities. Each bridge will be completely independent of the others and uses its own port for matter.

[!NOTE] You can use one bridge to connect to multiple controllers.

[!WARNING] Alexa only supports port 5540. Therefore, you cannot create multiple bridges to connect with Alexa.

Every bridge has to have a name (string), port (number) and filter (object) property. The filter property has to include an include (array) and an exclude (array) property.

{
  "name": "My Hub",
  "port": 5540,
  "filter": {
    "include": [],
    "exclude": []
  }
}

A include- or exclude-item is an object having a type and a value property. The type can be one of:

• pattern - a pattern matching your entity ids
• domain - the domain you want to include or exclude
• platform - the integration you want to include or exclude
• label - the slug of a label you want to include or exclude

The value property is a string containg the corresponding value. You can add multiple include or exclude rules which are then combined. All entities which match one of the include-rules will be included, but all entities which match one of the exclude rules will be excluded.

{
  "name": "My Hub",
  "port": 5540,
  "filter": {
    "include": [
      {
        "type": "label",
        "value": "my_voice_assist"
      },
      {
        "type": "pattern",
        "value": "light.awesome*"
      }
    ],
    "exclude": [
      {
        "type": "platform",
        "value": "hue"
      },
      {
        "type": "domain",
        "value": "fan"
      }
    ]
  }
}
