Modularity always helps when it comes to the maintenance of complex systems, and so it should help when it comes to managing Home Assistant. A while back, I stumbled across Frenck’s GitHub profile, where he was showcasing his Home Assistant config - https://github.com/frenck/home-assistant-config. I found the idea of splitting each entry into it’s own dedicated file, rather then having one huge config file, much more intuitive and easier to manage.

Setup

Navigate to your data folder

103:43:35 vivaan@ultimate ~ → cd /clstr/homeassistant/data

Create a new integrations folder

This will be where all the entries for Home Assistant’s config will be stored.

103:55:50 vivaan@ultimate data → mkdir integrations
203:56:53 vivaan@ultimate data → ls integrations/
303:57:02 vivaan@ultimate data →

Configure configuration.yaml to look in the integrations folder

Add the following to the bottom of your configuration file:

1homeassistant:
2  packages: !include_dir_named integrations

Restart Home Assistant

Examples

Say if you want to move your default_config section to this new modular structure:

• First, create a file named default_config.yaml

• Add the following

  1default_config:
  

• and remove that line from configuration.yaml

Notes

• Make sure you don’t have any duplicate keys in your configuration.yaml file - i.e. you should only have one homeassistant:
• Home Assistant should validate the configuration before restarting, so as long as it pass that check you should be good to go

Final Thoughts

Overall, the introduction of a modular structure should make it easier to maintain and change things, as it’ll be pretty simple to work out the location of where something is. As well as this, it should mean that your configuration.yaml file remains pretty small and readable.
