What should be done in Z2M?
Do you expect it to ignore / skip those values?

[pvvx]

I expect adequate values, taking into account specific values.
Preferably similar to ZHA.
Value: 0xffff -> Unknown

    def formatter(self, value: int) -> int | None:
        """Convert illumination data."""
        if self._is_non_value(value):
            return None
        if value == 0:
            return 0
        return round(pow(10, ((value - 1) / 10000)))
