devolo Home Control API in Python

devolo_home_control_api

This project implements parts of the devolo Home Control API in Python. It is based on reverse engineering and therefore may fail with any new devolo update. If you discover a breakage, please feel free to report an issue.

System requirements

Defining the system requirements with exact versions typically is difficult. But there is a tested environment:

• Linux
• Python 3.6.9
• pip 18.1
• requests 2.22.0
• websocket_client 0.56.0
• zeroconf 0.24.4

Other versions and even other operating systems might work. Feel free to tell us about your experience. If you want to run our unit tests, you also need:

• pytest 4.5.0
• pytest-mock 1.11.2

Versioning

In our versioning we follow Semantic Versioning.

Installing for development

First, you need to get the sources.

git clone [e-mail]:2Fake/devolo_home_control_api.git

Then you need to take care of the requirements.

pip install --user --requirement devolo_home_control_api/requirements.txt

If you want to run out tests, change to the tests directory and start pytest.

cd tests
pytest

Quick start

To see that basic functionality, please look at our small example. For this example, a working Home Control Central Unit must be attached to your my devolo account. After entering your my devolo username and password, simply run it:

python3 example.py

You will see changes to any BinarySwitch device (e.g. state or consumption) reported to your console. If the executing device is in the same LAN as the Home Control Central Unit, it will be discovered via Zeroconf. In this case, data will be collected from the Central Unit directly; otherwise data will be collected via cloud from my devolo.

Connecting to my devolo

If you do not know your gateway ID, you can ask my devolo. For now, no other functionality is implemented, that you would need to access directly. If you discover other use cases, feel free to file a feature request.

mydevolo = Mydevolo.get_instance()
mydevolo.user = "username"
mydevolo.password = "password"
for gateway_id in mydevolo.gateway_ids:
    print(gateway_id)

Collecting Home Control data

There are three ways of getting data:

1. Poll the gateway
2. Let the websocket push data into your object, but still poll the object
3. Subscribe to the publisher and let it push (preferred)

Poll the gateway

When polling the gateway, each property will be checked at the time of accessing it.

mprm = MprmRest(gateway_id=gateway_id)
for binary_switch in mprm.binary_switch_devices:
    for state in binary_switch.binary_switch_property:
        print (f"State of {binary_switch.name} ({binary_switch.binary_switch_property[state].element_uid}): {binary_switch.binary_switch_property[state].state}")

To execute this example, you need a configured instance of Mydevolo.

Using websockets

Your way of accessing the data is more or less the same. Websocket events will keep the object up to date. This method uses less resources on the devolo Home Control Central Unit.

mprm = MprmWebsocket(gateway_id=gateway_id)
for binary_switch in mprm.binary_switch_devices:
    for state in binary_switch.binary_switch_property:
        print (f"State of {binary_switch.name} ({binary_switch.binary_switch_property[state].element_uid}): {binary_switch.binary_switch_property[state].state}")

To execute this example, you again need a configured instance of Mydevolo.

Using subscriber

This preferred usage is shown in our small example. On every websocket event, update() will be called. That way you can react to changes right away.
