The Dashboard Problem
Home Assistant is incredible. But controlling it means opening an app, finding the right dashboard, tapping the right entity. What if you could just text your house?
“Turn off all the lights downstairs.” “What’s the temperature in the garage?” “Set the thermostat to 20°C when I leave.”
That’s what OpenClaw + Home Assistant gives you.

Step 1: Create a Long-Lived Access Token in HA
Go to your Home Assistant profile → Security → Long-Lived Access Tokens → Create Token.
Step 2: Configure OpenClaw
# openclaw.yaml
tools:
home-assistant:
type: rest-api
baseUrl: http://homeassistant.local:8123
headers:
Authorization: "Bearer YOUR_HA_TOKEN"Step 3: Create a Home Assistant Skill
# skills/home-assistant/SKILL.md
## Home Assistant Control
When the user asks to control home devices:
1. Query HA API for entity states: GET /api/states
2. Match natural language to entity IDs
3. Call services: POST /api/services/{domain}/{service}
Common mappings:
- "lights" → light.* entities
- "temperature" → sensor.*_temperature
- "thermostat" → climate.* entities
- "lock/unlock" → lock.* entitiesReal-World Examples
Me: “Good night” OpenClaw: Turns off all lights, locks front door, sets thermostat to 18°C, arms alarm system.
Me: “Is the garage door open?” OpenClaw: Checks cover.garage_door state → “Yes, the garage door has been open for 2 hours. Want me to close it?”
Me: “Too warm in the office” OpenClaw: Checks sensor.office_temperature (26°C), turns on fan.office, adjusts climate.office to 22°C.
Automations That Talk Back
The real power is bidirectional. Home Assistant can trigger OpenClaw messages:
# HA automation: notify via OpenClaw when washing machine finishes
automation:
- alias: "Washing Machine Done"
trigger:
- platform: state
entity_id: sensor.washing_machine_power
to: "0"
for: "00:05:00"
action:
- service: rest_command.openclaw_notify
data:
message: "Washing machine finished 5 minutes ago"OpenClaw receives this and forwards to your Discord/WhatsApp with context.
