Points of interest

• Home-Assistant is running within a kubernetes cluster running the the home-assistant helm chart
• Automations are mostly performed via node-red with the node-red configuration hosted in this repo
• In addition to use git to control the configuration, an embeded instance of the VSCode server using the home-assistant config helper extension is leveraged to make live changes to the configuration files

Recent Refactoring (December 2024)

This configuration underwent a major refactoring to modernize deprecated syntax and reduce code duplication through blueprints.

Key Improvements

Code Reduction:

• automation/alarm.yaml: 403 → 229 lines (43% reduction)
• config/mqtt.yaml: 690 → 199 lines (71% reduction)
• Overall ~45% reduction in targeted files

Modernizations:

• Removed all deprecated data_template syntax (30 instances)
• Migrated from deprecated iOS notification actions to mobile_app events
• Modernized template sensors with unique IDs and null-safe checks
• Created custom blueprints for reusable automation patterns

New Features:

• Custom blueprints in blueprints/automation/custom/:
  • sensor_alert_when_away.yaml - Alerts when sensors trigger while nobody home
  • sensor_alert_timeout.yaml - Alerts when sensors stay open too long
• Better organization of Tesla MQTT sensors (grouped by category vs by car)

Rollback: Git tag pre-refactor-20241214 marks the pre-refactoring state for easy rollback if needed.
