My Home Assistant configuration
Not quite everything will be uploaded here, because some things should be kept private.
If you are going to put your config into a git repo, please bear this in mind.
As an example of what can happen, I've included an API key in one of my files - Openweathermap.
It took a couple days to be seen, and then my API key was being used in multiple places.
I have since invalidated this key.
Any time you are working with git, you should make use of a .gitignore file. Mine can be found here.
In essence, this file tells the git client what files not to push up to the repository.
Things that identify devices, things that keep a history (like the hass database) should be held back. Logging when you are and aren't home and posting it publicly is not good practice at all.
In order to still use git for things, HAss has the option for using a "secrets.yaml" file (in the /config directory).
Use this to define all the things that are needed for use but shouldn't be public - like API keys, passwords, UIDs etc.
I'm slowly changing things and working on ways to define people and locations through this sheet, just for security.
To use the secrets file, enter a corresponding key in the file for use elsewhere.
For example:
In configuration.yaml, where it says !secret trusted_proxy1, I then have an entry in secrets.yaml with the IP of one of my reverse proxy hosts (trusted_proxy1: 1.2.3.4)
Where it says !secret service_api_key in a sensor configuration file, I then have an entry in secrets.yaml with the API key of the relevant service (service_api_key: thisisnotanactualkey)
This allows me to use the configuration files without exposing passwords or access keys.
In order to allow me to roll back things, I'm using github. It's not a perfect example, nor is my code always clean, but if it helps someone else figure something out then so much the better.
