		// Actually, integration tests usually invoke the method that handles the command.
		// BaseDeviceFeatures.command()? No, that's abstractish.

		// Let's verify via 'requestsHandler.sendRequest' by calling the feature's command method if exposed?
		// No, commands are registered in 'this.commands'.

		// Since we can't easily trigger the full adapter 'onStateChange' pipeline without more setup,
		// let's verify that the *intent* works by testing the underlying request logic directly or
