You should see this at the top of the page:

import requests

# Home Assistant settings
BASE_URL = "http://(your HA server IP):8123/api"
TOKEN = "(your long-lived HA access token)"

# Headers for authentication
HEADERS = {
    "Authorization": f"Bearer {TOKEN}",
    "Content-Type": "application/json"
}

def toggle_light(entity_id):
    """Toggle a light entity in Home Assistant."""
    url = f"{BASE_URL}/services/light/toggle"
    data = {"entity_id": entity_id}
    
    response = requests.post(url, json=data, headers=HEADERS)
    
    if response.status_code == 200:
        print(f"Successfully toggled {entity_id}.")
    else:
        print(f"Failed to toggle {entity_id}. Status code: {response.status_code}, Response: {response.text}")

# Example usage
if __name__ == "__main__":
    light_entity_id = "switch.laptop_calculator"  # Replace with your entity ID
    toggle_light(light_entity_id)

The above script shows how to flip a switch, including the virtual switches you get from the official TRIGGERcmd integration.
