We should add a translation dict between the myq status and home assistant state constants. This will make sure we control the coupling, and avoid breakage if a constant changes.

I think I follow, something like this then?

MYQ_TO_HASS = {
    'closed': STATE_CLOSED,
    'closing': STATE_CLOSING,
    'opening': STATE_OPENING
}

    @property
    def is_closing(self):
        """Return if the cover is closing or not."""
        return MYQ_TO_HASS[self._status] == STATE_CLOSING

Exactly! 👍
