将Homegraph api集成到我的smarthome

from google.oauth2 import service_account
from googleapiclient.discovery import build

# 设置API密钥和范围
SCOPES = ['https://www.googleapis.com/auth/homegraph']
SERVICE_ACCOUNT_FILE = 'path/to/service-account-file.json'

credentials = service_account.Credentials.from_service_account_file(
    SERVICE_ACCOUNT_FILE, scopes=SCOPES)

service = build('homegraph', 'v1', credentials=credentials)

# 查询设备状态
def query_devices():
    response = service.devices().query(body={}).execute()
    return response

# 发送控制命令
def send_command(device_id, command):
    body = {
        "agentUserId": "user-id",
        "devices": [
            {
                "id": device_id,
                "command": command
            }
        ]
    }
    response = service.devices().execute(body=body).execute()
    return response

# 示例调用
devices = query_devices()
print(devices)

command_response = send_command('device-id', {'turnOn': {}})
print(command_response)
