aioremootio - An asynchronous API client library for Remootio

aioremootio is an asynchronous API client library for Remootio written in Python 3 and based on asyncio and aiohttp.

Supported functionalities of the device

With this client library is currently possible to listen to state changes of a Remootio device, to listen to some events triggered by it, furthermore to operate the gate or garage door connected to it.

This client library supports currently the listening to following kind of events triggered by the device:

• STATE_CHANGE which is triggered by the device when its state changes
• RELAY_TRIGGER which is triggered by the device when its control output has been triggered to operate the connected gate or garage door
• LEFT_OPEN which is triggered by the device when the connected gate or garage door has been left open
• RESTART which is triggered by the device when it was restarted

Using the library

The following example demonstrates how you can use this library.

from typing import NoReturn
import logging
import asyncio
import aiohttp
import aioremootio


class ExampleStateListener(aioremootio.Listener[aioremootio.StateChange]):
    __logger: logging.Logger

    def __init__(self, logger: logging.Logger):
        self.__logger = logger

    async def execute(self, client: aioremootio.RemootioClient, subject: aioremootio.StateChange) -> NoReturn:
        self.__logger.info("State of the device has been changed. Host [%s] OldState [%s] NewState [%s]" %
                           (client.host, subject.old_state, subject.new_state))


async def main() -> NoReturn:
    logger = logging.getLogger(__name__)
    logger.setLevel(logging.INFO)

    handler: logging.Handler = logging.StreamHandler()
    handler.setFormatter(logging.Formatter(fmt="%(asctime)s [%(levelname)s] %(message)s"))
    logger.addHandler(handler)

    connection_options: aioremootio.ConnectionOptions = \
        aioremootio.ConnectionOptions("192.168.0.1", "API_SECRET_KEY", "API_AUTH_KEY")

    state_change_listener: aioremootio.Listener[aioremootio.StateChange] = ExampleStateListener(logger)

    remootio_client: aioremootio.RemootioClient
    
    async with aiohttp.ClientSession() as client_session:
        try:
            remootio_client = await aioremootio.RemootioClient(
                connection_options,
                client_session,
                aioremootio.LoggerConfiguration(logger=logger),
                [state_change_listener]
            )
        except aioremootio.RemootioClientConnectionEstablishmentError:
            logger.exception("The client has failed to establish connection to the Remootio device.")
        except aioremootio.RemootioClientAuthenticationError:
            logger.exception("The client has failed to authenticate with the Remootio device.")
        except aioremootio.RemootioError:
            logger.exception("Failed to create client because of an error.")
        else:
            logger.info("State of the device: %s", remootio_client.state)
    
            if remootio_client.state == aioremootio.State.NO_SENSOR_INSTALLED:
                await remootio_client.trigger()
            else:
                await remootio_client.trigger_open()
                await remootio_client.trigger_close()
    
        while True:
            await asyncio.sleep(0.1)

if __name__ == "__main__":
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        pass

To get the API Secret Key and API Auth Key of your Remootio device you must enable the API on it according to the Remootio Websocket API documentation.

Running the bundled examples

The project source does also contain two examples.

The example example.py demonstrates how you can use the client as a Python object.

The example example_mc.py demonstrates how you can use the client as a Python object where it does not establish a connection to the Remootio device automatically during its initialization.

The example example_acm.py demonstrates how you can use the client as an asynchronous context manager.

To run the bundled examples you must

1. also enable the API on your Remootio device to get the API Secret Key and API Auth Key of it, and
2. add the source folder /src of the repository to your PYTHONPATH.

After the two steps described above you can run the bundled examples with the argument --help to show the usage information. E.g.:

python example.py --help

Running the bundled tests

To run the bundled tests you must create the .\remootio_device.configuration.json file with a content according to the following template.

{
    "host": "IP-ADDRESS-OR-HOST-NAME-OF-YOUR-DEVICE",
    "api_secret_key": "API-SECRET-KEY-OF-YOUR-DEVICE",
    "api_auth_key": "API-AUTH-KEY-OF-YOUR-DEVICE",
    "api_version": API-VERSION-OF-YOUR-DEVICE
}
