Helper Script

A nest CLI helper is included at scripts/nest:

# Make it available globally
ln -sf /Users/mitchellbernstein/clawd/skills/google-home/scripts/nest /usr/local/bin/nest

# List devices
nest list

# Get thermostat status
nest status "enterprises/PROJECT_ID/devices/DEVICE_ID"

# Set temperature (Celsius)
nest temp "enterprises/PROJECT_ID/devices/DEVICE_ID" 22

# Set mode
nest mode "enterprises/PROJECT_ID/devices/DEVICE_ID" HEAT

Configuration

Create ~/.config/google-home/config.json:

{
  "project_id": "your-google-cloud-project-id",
  "access_token": "your-oauth-access-token"
}

Notes

• Tokens expire; refresh them periodically
• Device names use full path: enterprises/PROJECT_ID/devices/DEVICE_ID
• Temperature is in Celsius (convert from Fahrenheit if needed)
• Camera streams require additional permissions
