# Turn on the light
api.call_service(“light”, “turn_on”, {“entity_id”: light_entity_id})
Change the light color
api.call_service(“light”, “turn_on”, {“entity_id”: light_entity_id, “rgb_color”: [255, 0, 0]})
Turn off the light
api.call_service(“light”, “turn_off”, {“entity_id”: light_entity_id})
b. Automate Thermostat:
“`python
import homeassistant_api
api = homeassistant_api.HomeAssistantAPI(“http://your-home-assistant-url:8123”, “your-api-token”)
thermostat_entity_id = “climate.living_room”
# Set the thermostat to a specific temperature
api.call_service(“climate”, “set_temperature”, {“entity_id”: thermostat_entity_id, “temperature”: 72})
c. Monitor Motion Sensors:
import homeassistant_api
api = homeassistant_api.HomeAssistantAPI(“http://your-home-assistant-url:8123”, “your-api-token”)
motion_sensor_entity_id = “binary_sensor.motion_sensor”
def motion_detected(data):
if data[“entity_id”] == motion_sensor_entity_id:
print(“Motion detected!”)
api.listen_state(motion_detected)
