aioesphomeapi
|
|
=============
|
|
|
|
``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
|
|
|
|
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."""
|
|
loop = asyncio.get_running_loop()
|
|
cli = aioesphomeapi.APIClient(loop, "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()
|
|
|

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
