SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Write or modify bashio-based shell scripts for the Home Assistant add-on. Use when editing run.sh, adding new features to the entrypoint script, or debugging the add-on's runtime behavior.

Core Features & Use Cases

  • Read configuration values with bashio::config to drive add-on behavior.
  • Log runtime events with bashio::log.* to ensure structured, safe output.
  • Access the Home Assistant Supervisor API and info helpers via bashio functions to interact with the environment.
  • Implement a robust entrypoint workflow with a watchdog loop pattern and basic startup/shutdown handling.
  • Use the script structure pattern to guide creation of reliable run.sh files.

Quick Start

Create a minimal run.sh that reads configuration via bashio and starts a watchdog loop.
