Audit Home Assistant Config with Claude Code

Updated 5 November 2026 · Standard formula, shown below

This guide walks you through auditing your Home Assistant configuration using Claude Code, an AI coding assistant that can review your YAML files, detect errors, and suggest improvements. You’ll learn how to run a safe, read-only analysis of your configuration, fix issues, and avoid common pitfalls. Before starting, ensure you have Home Assistant installed and a basic understanding of your configuration directory structure.

What You’ll Need

A working Home Assistant installation (Home Assistant OS, Supervised, Container, or Core).
Access to your configuration directory (usually /config on HA OS or the path where your configuration.yaml resides).
Claude Code installed on your local machine (requires Node.js 18+ and an Anthropic API key).
A text editor or terminal to review the generated reports.
Basic familiarity with YAML syntax and Home Assistant’s core concepts (entities, automations, scripts).

Step-by-Step

Back up your configuration. Before any audit, create a full backup of your configuration.yaml, automations.yaml, scripts.yaml, secrets.yaml, and any other YAML files. You can use the Home Assistant backup feature or manually copy the folder.
Install Claude Code. If not already installed, open a terminal and run npm install -g @anthropic-ai/claude-code. Verify with claude --version.
Navigate to your configuration directory. In the terminal, change to the folder containing your configuration.yaml. For example: cd /path/to/homeassistant/config.
Start Claude Code in read-only mode. Run claude --read-only. This ensures Claude cannot modify any files during the audit, keeping your configuration safe.
Request a configuration audit. Type a prompt like: “Please audit my Home Assistant configuration for errors, deprecated features, and security issues. Focus on YAML syntax, duplicate entities, and common misconfigurations. Do not modify any files.”
Review the initial report. Claude will scan your files and produce a list of findings. Read through each item carefully. It may point out syntax errors, invalid entity references, or outdated integrations.
Ask for specific checks. You can drill down by asking: “Check my automations for trigger/condition errors” or “Validate all device IDs in my scripts.” This helps uncover logic issues that a general scan might miss.
Request a security review. Ask: “Review my configuration for security best practices, such as exposed secrets, weak passwords, or overly permissive network settings.” Claude will flag items like plaintext passwords in secrets.yaml or open ports.
Generate a fix list. Ask Claude to produce a prioritized list of recommended changes, from critical (breaking) to minor (style). For each, ask for the exact YAML snippet that would fix it.
Apply fixes manually. Exit Claude Code (exit). Edit your YAML files with a text editor, applying only the changes you understand and have verified. Do not let Claude auto-apply changes unless you are confident in the modifications.
Validate your configuration. After making changes, run python3 -m homeassistant --config /path/to/config --script check_config (or use the Developer Tools > YAML in the HA UI) to ensure the configuration is still valid.
Restart Home Assistant. Restart HA to load the changes. Monitor the logs for new errors. If something breaks, restore the backup and re-evaluate the changes.
Repeat the audit periodically. After major upgrades or configuration changes, run the audit again to catch new issues.

Common Mistakes

Letting Claude auto-fix files without review. AI suggestions can be wrong or incomplete. Always verify changes manually.
Ignoring warnings about deprecated integrations. Deprecated features may stop working in future updates, causing silent failures.
Not backing up before the audit. Even a read-only audit can reveal issues that tempt you to make changes without a safety net.
Using Claude Code on a live production system without testing. Always test changes in a staging environment if possible.
Overlooking secrets management. Claude may flag plaintext secrets, but you must manually move them to environment variables or the HA secrets system.

Tips

Use the --read-only flag every time you run Claude Code for auditing. It prevents accidental file modifications.
Break the audit into sections: YAML syntax, automations, scripts, integrations, and security. This makes the output more manageable.
Ask Claude to explain why a particular pattern is problematic. Understanding the reason helps you avoid similar issues in the future.
Keep your secrets.yaml out of the audit scope if you’re concerned about sensitive data being processed by an external AI. You can exclude it by asking Claude to skip that file.
After applying fixes, run the HA configuration check and review the logs for at least 24 hours to ensure stability.

Troubleshooting

Claude Code cannot access your configuration directory. Ensure you have the correct file permissions and that the path is correct. Try running claude from the directory directly.
The audit report is too generic. Provide more context in your prompt, such as “I’m using Home Assistant 2024.1” or “I have many Zigbee devices.” This helps Claude tailor the analysis.
Claude suggests changes that break your setup. If a fix causes errors, revert that specific change. Use version control (e.g., Git) to track changes and roll back easily.
Claude Code is slow or times out. Large configurations can take time. Try narrowing the scope to specific files or directories.
You’re unsure about a recommendation. Ask Claude to provide the official Home Assistant documentation reference for that pattern. Verify it before applying.
After applying fixes, Home Assistant won’t start. Restore your backup and re-apply changes one at a time, checking the config after each change.

Frequently Asked Questions

Is it safe to use Claude Code on my Home Assistant configuration?

Yes, if you use the --read-only flag and review all suggestions manually. The AI cannot modify files in read-only mode, so the risk is minimal.

Can Claude Code fix my configuration automatically?

It can, but it’s not recommended. Auto-fixes may introduce new errors or unintended changes. Manual application with review is safer.

What kinds of issues can the audit detect?

It can detect YAML syntax errors, duplicate entity IDs, invalid references, deprecated integrations, security concerns like exposed secrets, and logic errors in automations and scripts.

Will the audit work with encrypted secrets?

Claude Code reads plaintext files. If your secrets are encrypted (e.g., using a custom encryption layer), it cannot decrypt them. You may need to temporarily provide decrypted versions or skip those files.

How often should I audit my configuration?

After every major change or upgrade, and at least once a month as a routine check. Regular audits help catch issues before they cause downtime.

Does Claude Code require an internet connection?

Yes, it sends your configuration files to Anthropic’s servers for processing. If you’re concerned about privacy, avoid including sensitive files like secrets.yaml in the audit.
