Wrong example for sending a command

[farshidtz]

I find it hard to make sense of the example given for sending a command:

python-matter-server/README.md

Lines 270 to 280 in dd6acaa

	command = clusters.OnOff.Commands.On()
	payload = dataclass_to_dict(command)
	{
	"message_id": "device_command",
	"command": "device_command",
	"args": {
	"endpoint": int(self.attribute['endpoint']),
	"node_id": int(self.attribute['node_id']),
	"payload": payload
	}
	}

Are the message ID and command values correct? Endpoint and node ID values reference some missing code. Is the given dictionary meant to be a JSON example, outside the Python code?
How will the controller know which cluster command is being executed? In the given example, payload will be an empty object.

The JSON object for the On command should be, for example:

{
    "message_id": "4",
    "command": "device_command",
    "args": {
      "endpoint_id": 1,
      "node_id": 1,
      "payload": {},
      "cluster_id": 6,
      "command_name": "On"
    }
}

You can have a look at the included client for a reference implementation, together with Home Assistant.
