access

Writes Home Assistant credentials to `~/.claude/channels/home-assistant/.env` and verifies the connection. Requires a Long-Lived Access Token (generated in HA under Profile → Security → Long-Lived Access Tokens).

<quick_start> Save credentials: /home-assistant:access url=http://homeassistant.local:8123 token=<TOKEN>

Check status: /home-assistant:access (no args)

Guided setup: /home-assistant:access setup </quick_start>

<credential_format> ~/.claude/channels/home-assistant/.env:

HA_URL=http://homeassistant.local:8123
HA_TOKEN=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...

Strip trailing slash from HA_URL before writing. Single-quote values containing special characters. chmod 600 after writing. </credential_format>

**No args — status check:**

Read ~/.claude/channels/home-assistant/.env (missing = not configured) and show:

1. Server URL — HA_URL: show value or "not set".
2. Token — HA_TOKEN: show "set (masked)" or "not set".
3. Connection test — if both are present:

   http --ignore-stdin -b GET "${HA_URL%/}/api/" \
     "Authorization: Bearer $HA_TOKEN"
   

   • Success ({"message": "API running."}): show "Connection OK".
   • Failure: show HTTP status and error, suggest checking URL and token.
4. What next — based on state:
   • Not configured → show save command syntax.
   • Connection failed → suggest re-running with corrected values.
   • All OK → list available skills.

setup — guided setup:

Explain each credential:

• HA_URL: Base URL of your HA instance (e.g. http://homeassistant.local:8123 or https://ha.yourdomain.com).
• HA_TOKEN: Long-Lived Access Token. Generate one in HA under Profile → Security → Long-Lived Access Tokens → Create Token.

Then ask the user to run:

/home-assistant:access url=<URL> token=<TOKEN>

Explicit save — url=<URL> token=<TOKEN>:

Parse key=value pairs from $ARGUMENTS. Accept both url=/HA_URL= and token=/HA_TOKEN= forms (case-insensitive, strip HA_ prefix).

Required: both url and token. List absent keys and stop if missing.

1. mkdir -p ~/.claude/channels/home-assistant
2. Read existing .env if present; update/add provided keys, preserve others.
3. Strip trailing slash from HA_URL before writing.
4. Write back as KEY=value (single-quote values with special characters).
5. chmod 600 ~/.claude/channels/home-assistant/.env
6. Test connection (same as status check above).
7. Show result and full status.

clear — remove credentials:

Delete ~/.claude/channels/home-assistant/.env. Confirm first: "This will remove all Home Assistant credentials. Are you sure?"

<security_checklist>

• Never display HA_TOKEN in full — show only "set (masked)" or first 8 chars + ...
• Always chmod 600 the .env file after writing
• Always strip trailing slashes from HA_URL
• If TLS error on connection test, suggest checking http:// vs https:// and certificate validity </security_checklist>

<success_criteria>

• Credentials written to ~/.claude/channels/home-assistant/.env with chmod 600
• Connection test returns {"message": "API running."}
• Token never fully exposed in output
• User knows exactly what to do next </success_criteria>
