Home Assistant Skill

Control your Home Assistant instance via REST API. Supports climate control, lights, switches, and sensor queries.

Purpose

This skill provides read and write access to your Home Assistant entities:

• Climate: Set temperature, HVAC mode, query current state
• Lights: Turn on/off, set brightness, color
• Switches: Toggle on/off
• Sensors: Query current values
• Services: Call any HA service

Setup

Credentials are stored in ~/.openclaw/credentials/homeassistant.json:

{
  "url": "http://192.168.2.82:8123",
  "token": "LONG_LIVED_ACCESS_TOKEN"
}

To generate a long-lived access token:

1. Open Home Assistant → Profile (bottom left)
2. Scroll to "Long-Lived Access Tokens"
3. Click "Create Token"
4. Name it "clawd" and copy the token

Commands

All commands use the HA REST API. Output is human-readable by default, add json for raw output.

Climate Control

Set thermostat temperature and mode:

# Set temperature (auto-selects cool/heat based on setpoint vs current)
bash scripts/climate.sh set <entity_id> <temperature>

# Set specific mode (cool, heat, auto, off)
bash scripts/climate.sh mode <entity_id> <mode>

# Get current climate state
bash scripts/climate.sh status <entity_id>
bash scripts/climate.sh status <entity_id> json

Examples:

# Set to 73°F cooling
bash scripts/climate.sh set climate.living_room 73 cool

# Turn off thermostat
bash scripts/climate.sh mode climate.living_room off

# Check current temperature
bash scripts/climate.sh status climate.living_room

List Entities

Find entity IDs for climate, lights, switches:

# List all climate entities
bash scripts/entities.sh climate

# List all light entities
bash scripts/entities.sh light

# List all switch entities
bash scripts/entities.sh switch

# List all entities of a domain
bash scripts/entities.sh all

Light Control

# Turn on
bash scripts/light.sh on light.living_room

# Turn off
bash scripts/light.sh off light.living_room

# Set brightness (0-255)
bash scripts/light.sh brightness light.living_room 128

# Set color (RGB)
bash scripts/light.sh color light.living_room 255 0 0

# Get state
bash scripts/light.sh status light.living_room

Switch Control

# Toggle switch
bash scripts/switch.sh toggle switch.bedroom_fan

# Turn on/off
bash scripts/switch.sh on switch.bedroom_fan
bash scripts/switch.sh off switch.bedroom_fan

Sensor Query

# Get sensor value
bash scripts/sensor.sh get sensor.temperature_outside
bash scripts/sensor.sh get sensor.humidity_living_room json

Call Service

Direct service call for advanced use:

# Generic service call
bash scripts/service.sh call <domain> <service> <entity_id> '[{"key": "value"}]'

# Example: Set temperature via climate.set_temperature
bash scripts/service.sh call climate set_temperature climate.living_room '{"temperature": 73}'

Entity Discovery

If you don't know the entity ID:

# Find all climate entities
bash scripts/entities.sh climate

# Find entities by name (fuzzy search)
bash scripts/entities.sh search thermostat
bash scripts/entities.sh search temperature

Common Workflows

1. "Make it cold" / "Turn on AC" → Find climate entity → Set to cool mode at desired temp
2. "Turn off the lights" → List light entities → Turn off specific or all
3. "What's the temperature?" → Query temperature sensor
4. "Set thermostat to 73" → Set climate entity to 73°F

Error Handling

If the command fails:

• Check HA is reachable: curl -s http://192.168.2.82:8123
• Verify token is valid (regenerate if needed)
• Confirm entity ID exists: bash scripts/entities.sh climate

Notes

• HA URL: http://192.168.2.82:8123 (from MEMORY.md)
• All calls use long-lived access token (no OAuth refresh needed)
• Climate mode mappings: cool, heat, auto, off, heat_cool
• Temperature unit follows HA configuration (°F for US)
