Stop Fighting YAML — Write Your Home Assistant Automations in Typed Python 
Have you ever had automations break because of a YAML/Jinja typo? Or because an entity disappeared and your automations silently failed?
Do you fear editing automations because of the tooling and syntax?
That ends now.
Introducing: Home Assistant Python Typer
Leverage real software development tools to write and maintain your automations with confidence — just like any modern application.
Home Assistant Python Typer makes your code editor (like VSCode) fully aware of all the entities and services in your own Home Assistant instance. You get:
Auto-completion
Red error highlights when something is wrong
Type safety for services, arguments, and entity states
Actual Python, not fragile YAML/Jinja
Example (from VSCode):
Here you can see:
- Auto-complete for entity IDs and service names
- Argument validation (e.g., only certain colors are valid)
- Errors when using unavailable or incorrect entities or impossible states
