mobilus-client 0.2.1

Mobilus Cosmo GTW Client

This code provides a native Python client for the Mobilus Cosmo GTW. It connects directly to the gateway's MQTT broker and sends message commands to control the associated devices. The connection is established locally, so the client must be run on the same network as the gateway. Note: internet access is not required and can be disabled on the device.

In order to use the client, configuration and setup need to be done on the Mobilus Cosmo GTW side. This includes creating a user and pairing the devices with the gateway.

The story behind the reverse engineering of this device, covering both the motivation and the process, is described in this blog post.

Installation

Install the module with pip:

pip install mobilus-client

Usage

For convenience, the client can be run as a module:

python -m mobilus_client --host=GATEWAY_HOST --login=USER_LOGIN --password=USER_PASSWORD COMMANDS

Where:

• GATEWAY_HOST is the IP address of the gateway.
• USER_LOGIN and USER_PASSWORD are the user credentials to access the gateway.
• COMMANDS is a list of commands to be sent to the gateway.

Currently, the following commands are supported:

• current_state - Get the current state of the devices. Please note that in the case of shutters, the state may be delayed, especially when the shutter is controlled by a physical switch.

• devices_list - List all devices that are paired with the gateway.

• call_events:device_id=DEVICE_ID,value=VALUE - Send a command to the device. This can be used for actual control of the device (shutter).

  • DEVICE_ID - The ID of the device as returned from devices_list.
  • VALUE - The value to be sent to the device, currently one of "UP", "DOWN", "STOP", "ON", "OFF", a percentage value like "85%" or "DOWN:60$" (for shutters, with tilt control).

Multiple commands can be sent at once, separated by spaces:

python -m mobilus_client --host=192.168.2.1 --login=admin --password=my_password devices_list call_events:device_id=0,value=100% call_events:device_id=1,value=80%

Output is printed to the console in JSON format, and therefore the client command can be easily chained with jq for prettier output. For example:

python -m mobilus_client --host=192.168.2.1 --login=admin --password=my_password current_state | jq

Verbose mode can be enabled with the --verbose flag:

python -m mobilus_client --host=192.168.2.1 --login=admin --password=my_password --verbose current_state

Caveats

The client is tested with Mobilus Cosmo GTW and shutter devices only (COSMO 2WAY). However, it should also work with other devices supported by the Gateway (SENSO, COSMO, CMR, CGR, SWITCH, SWITCH_NP, COSMO_CZR, COSMO_MZR, SENSO_Z). The purpose of the client is to provide a simple way to control the devices without the need to use the official Mobilus Cosmo GTW web interface or app, and to integrate it with open-source systems like Home Assistant. I am not affiliated with Mobilus, and the client is provided as is.

Development

Clone the repository and navigate to the project directory. Install the package in editable mode with the following command:

pip install -e .[test]

Check mypy and ruff with the following commands:

mypy .
ruff check

The tests can be run with the following command:

python -m unittest -v

To generate a coverage report:

coverage run -m unittest discover
coverage report -m

To regenerate proto files

docker-compose up --build -f scripts/docker-compose.yml
