How to get object identifier from Kivy language in Python code

I created a widget in the Kivy language, it has some properties that I use for some of them inside this widget's pictorial code. Since I use the id keyword in the .kv file, all of them have id. I need to use the same identifiers inside Python code. Here is a workaround:

CcaSwitch:
    id: out0_bit3
    name: "out0_bit3"

I use self.name instead of self.id in python code. How can I achieve the same goal without a “repeating” entry for each widget?

Thank.

Edit

I use the "name" variable inside Python code as follows:

class CcaSwitch(BoxLayout):

    name = StringProperty()

    def __init__(self, *args, **kwargs):
        # ...
        Clock.schedule_interval(self.refresh, 5)

    def refresh(self, dt):
        self.comm.publish(get_bool_status(self.name), self.routing_key)

So, I need a string that identifies this instance of the widget itself, in a dry way.

I would like to achieve something like this:

In the .kv file:

CcaSwitch:
    id: out0_bit3

In Python, I would like to use it like:

 class CcaSwitch(BoxLayout):

    def __init__(self, *args, **kwargs):
        # ...
        self.name = self.id.__name__
        Clock.schedule_interval(self.refresh, 5)

    def refresh(self, dt):
        self.comm.publish(get_bool_status(self.name), self.routing_key)
