sorry, I'm not fully understand it.
anyway, is this possible to merge if self.hass.is_stopping and if not self.hass ?
if not possible, maybe we still can add a error or warning debug log in self.hass.is_stopping

I do agree with @wuwentao
You need to check self.hass first

[chemelli74]

update is called by core, so hass is there at the time of invocation. It cannot happen it's not

No, I can certainly confirm that:

if not self.hass:
            _LOGGER.error(
                "Midea entity update_state for %s [%s] with status %s",

it has been matched in my device error log,
but I'm not enable the debug log, only one line error log exist, so I can't find out the root cause when this error exist.

[chemelli74]

There must be a issue, probably a thread issue, as update cannot be called if hass is None.

I'll add a check, but with a note that we need to investigate.
