aioesphomeapi ============= .. image:: https://github.com/esphome/aioesphomeapi/workflows/CI/badge.svg :target: https://github.com/esphome/aioesphomeapi?query=workflow%3ACI+branch%3Amain .. image:: https://img.shields.io/pypi/v/aioesphomeapi.svg :target: https://pypi.python.org/pypi/aioesphomeapi .. image:: https://codecov.io/gh/esphome/aioesphomeapi/branch/main/graph/badge.svg :target: https://app.codecov.io/gh/esphome/aioesphomeapi/tree/main ``aioesphomeapi`` allows you to interact with devices flashed with `ESPHome <https://esphome.io/>`_. Installation ------------ The module is available from the `Python Package Index <https://pypi.python.org/pypi>`_. .. code:: bash $ pip3 install aioesphomeapi An optional cython extension is available for better performance, and the module will try to build it automatically. The extension requires a C compiler and Python development headers. The module will fall back to the pure Python implementation if they are unavailable. Building the extension can be forcefully disabled by setting the environment variable ``SKIP_CYTHON`` to ``1``. Usage ----- It's required that you enable the `Native API <https://esphome.io/components/api.html>`_ component for the device. .. code:: yaml # Example configuration entry api: password: 'MyPassword' Check the output to get the local address of the device or use the ``name:``under ``esphome:`` from the device configuration. .. code:: bash [17:56:38][C][api:095]: API Server: [17:56:38][C][api:096]: Address: api_test.local:6053 The sample code below will connect to the device and retrieve details. .. code:: python import aioesphomeapi import asyncio async def main(): """Connect to an ESPHome device and get details.""" # Establish connection api = aioesphomeapi.APIClient("api_test.local", 6053, "MyPassword") await api.connect(login=True) # Get API version of the device's firmware print(api.api_version) # Show device details device_info = await api.device_info() print(device_info) # List all entities of the device entities = await api.list_entities_services() print(entities) loop = asyncio.get_event_loop() loop.run_until_complete(main()) Subscribe to state changes of an ESPHome device. .. code:: python import aioesphomeapi import asyncio async def main(): """Connect to an ESPHome device and wait for state changes.""" cli = aioesphomeapi.APIClient("api_test.local", 6053, "MyPassword") await cli.connect(login=True) def change_callback(state): """Print the state changes of the device..""" print(state) # Subscribe to the state changes await cli.subscribe_states(change_callback) loop = asyncio.get_event_loop() try: asyncio.ensure_future(main()) loop.run_forever() except KeyboardInterrupt: pass finally: loop.close() Other examples: - `Camera <https://gist.github.com/micw/202f9dee5c990f0b0f7e7c36b567d92b>`_ - `Async print <https://gist.github.com/fpletz/d071c72e45d17ba274fd61ca7a465033#file-esphome-print-async-py>`_ - `Simple print <https://gist.github.com/fpletz/d071c72e45d17ba274fd61ca7a465033#file-esphome-print-simple-py>`_ - `InfluxDB <https://gist.github.com/fpletz/d071c72e45d17ba274fd61ca7a465033#file-esphome-sensor-influxdb-py>`_ Development ----------- For development is recommended to use a Python virtual environment (``venv``). .. code:: bash # Setup virtualenv (optional) $ python3 -m venv . $ source bin/activate # Install aioesphomeapi and development depenencies $ pip3 install -e . $ pip3 install -r requirements_test.txt # Run linters & test $ script/lint # Update protobuf _pb2.py definitions (requires a protobuf compiler installation) $ script/gen-protoc A cli tool is also available for watching logs: .. code:: bash aioesphomeapi-logs --help A cli tool is also available to discover devices: .. code:: bash aioesphomeapi-discover License ------- ``aioesphomeapi`` is licensed under MIT, for more details check LICENSE.
