Home Assistant (REST) — Quick Use

Security first

• Prefer a dedicated Home Assistant user for this assistant.
• Use a Long-Lived Access Token (LLAT) from that user.
• Never commit tokens to git; store them in secrets/ (gitignored).
• If HA is exposed on the public internet, ensure HTTPS, strong auth, and ideally IP restrictions / VPN.

Setup (one-time)

1. Set your HA base URL (you have: https://ghar.nicolaischmid.de).
2. Save token to a local secret file:
   • mkdir -p /root/.openclaw/workspace/secrets
   • chmod 700 /root/.openclaw/workspace/secrets
   • write token to: /root/.openclaw/workspace/secrets/ha_token
   • chmod 600 /root/.openclaw/workspace/secrets/ha_token

Optional env overrides:

• HA_URL (default taken from secrets/ha_url if present)
• HA_TOKEN (default read from secrets/ha_token)

Inventory / context

• The current device/entity overview lives in:
  • skills/homeassistant/references/inventory-nice.md (most useful controls)
  • skills/homeassistant/references/inventory.md (broader controllable list)
• Refresh anytime by running:
  • node scripts/ha-refresh-context.mjs

Commands

Wrapper script (JSON by default):

• Ping:

  • node scripts/ha.mjs ping

• Get entity state:

  • node scripts/ha.mjs state light.living_room

• Call a service:

  • node scripts/ha.mjs call light turn_on '{"entity_id":"light.living_room","brightness_pct":50}'

• List entities (compact):

  • node scripts/ha.mjs list --domain light

REST endpoints (reference)

• GET /api/
• GET /api/states/<entity_id>
• POST /api/services/<domain>/<service> with JSON body
