Integration with Cron

*/30 * * * * bash /path/to/ha-toolkit.sh state cover.garage_door | grep -q "open" && echo "Garage is open!" | mail -s "Alert" you@example.com

Error Handling

The toolkit validates:

• HA_URL and HA_TOKEN are set before any API call
• HTTP response codes (401 unauthorized, 404 not found, etc.)
• JSON parsing with graceful fallback
• Network connectivity with timeout controls

Troubleshooting

"Connection refused" — Verify HA is running and the URL is correct. Check firewall rules.

"401 Unauthorized" — Your token may be expired or invalid. Generate a new one from the HA profile page.

"Entity not found" — Use entities command to list valid entity IDs. Check domain prefix (e.g., light. vs switch.).

Security Notes

• Tokens are read from environment variables only — never stored on disk by the script
• All API calls use HTTPS when your HA instance supports it
• Consider using a dedicated HA user with limited permissions for automation scripts
