   cd core
   

   Note: cd core is a convenient command to switch to the project folder in the command line.

3. Install Required Packages: Next, you’ll need to install the necessary dependencies to run the project. Use the following command:

   pip install -r requirements_all.txt
   

   Note: This command reads the list of dependencies in the file and installs them to ensure that the project runs smoothly!

Using Core 🌟

Once Core is installed, you’re ready to configure and start using it! Below are some sample configuration files to help you understand how to set up and personalize your environment.

Configuring Home Assistant 🏡

Here’s a basic configuration example for Home Assistant:

homeassistant:
  name: Home                     # This is the name you set for your Home Assistant
  latitude: 32.87336             # Latitude of your residence
  longitude: 117.22743           # Longitude of your residence
  elevation: 430                 # Elevation of your home
  radius: 100                    # Specify the monitoring radius around your home
  unit_system: metric            # Choose the metric unit system

    - "/usr/var/dumping-ground"  # Allowed external storage directory
    - "/tmp"                      # Allowed temporary directory
  allowlist_external_urls:       # Configure external URL allowlist
    - "http://images.com/image1.png" # URL for external images
  media_dirs:                    # Media file storage directories
    media: "/media"              # Directory for media files
    recordings: "/mnt/recordings" # Directory for saved recordings
  debug: false                   # Turn off debug mode

Note: This YAML configuration file defines essential information to ensure Home Assistant knows its environment and how to operate.

Customizing Devices and Entities 🔧

In this section, you can customize device settings! Here’s a configuration example for a thermostat and switches:

customize:
  thermostat.family_room:
    entity_picture: https://example.com/images/nest.jpg  # Link to the thermostat image
    friendly_name: Nest                                   # Set a friendly name for the thermostat
  switch.wemo_switch_1:
    friendly_name: Toaster                               # Assign an easy-to-recognize name to the switch
    entity_picture: /local/toaster.jpg                  # Path to the image
  switch.wemo_switch_2:
    friendly_name: Kitchen kettle                         # Friendly name for another switch
    icon: mdi:kettle                                     # Add an icon to the switch
  media_player.my_media_player:
    source_list:                                         # Available source list for the media player
      - Channel/input from my available sources         # Channel/input source

Note: Customization allows you to manage devices more easily, enhancing the user experience of your smart home!

Setting Up WebRTC 🌐

If you want to use WebRTC features for real-time communication, you can include the following configuration:

webrtc:
  ice_servers:
    - url:
      - "stun:stun.example.com:19302"                   # Set STUN server to obtain the public IP of the user
      - "stun:stun2.example.com:12345"                  # Backup STUN server
    - url: "turn:turn.domain.com"                        # TURN server for relay
      username: "username"                                # Username for the TURN server
      credential: "abc123"                               # Credential for the TURN server

Note: This configuration enables WebRTC to connect through STUN and TURN servers, enhancing real-time communication, allowing us to connect more smoothly!

Action Configuration ⚙️

You can define actions that can be executed! For example, here’s a simple example of setting a location:

actions:
  - action: homeassistant.set_location                    # Specify the action type
    data:
      latitude: 32.87336                                  # Define latitude
      longitude: 117.22743                                # Define longitude
      elevation: 120                                      # Define elevation

Note: This allows Home Assistant to understand and update the current location, making the smart home smarter!

Asynchronous Setup Example ⚡

If you want to use asynchronous methods in the code, you can refer to this example:

DOMAIN = "hello_state"                                     # Define the module name

async def async_setup(hass, config):                      # Asynchronous setup function
    hass.states.async_set("hello_state.world", "Paulus") # Set the initial state
    return True                                            # Return boolean to indicate success

Note: Using asynchronous programming can enhance your application’s efficiency, allowing non-blocking state settings.

JSON Configuration Example 🗄️

To add a module in the configuration file, you can refer to this JSON example:

{
  "domain": "hello_state",                                 # Module domain
  "name": "Hello, state!",                                 # Module name
  "version": "0.1.0"                                      # Module version
}

Note: This JSON code defines basic information about the module, including its name and version number, making it easier for the system to recognize and load.

With these steps and examples, you can easily install and start using Core and enjoy the fun and accomplishment of smart home development! 🎉 Let’s welcome the new era of smart homes together!
