Using self.async_update_ha_state() #99

[ercsey]

Fixes issue #99

Thanks for your contribution.

I would like to merge this in. Can you explain why line 319 was removed rather than replaced with a call to async_write_ha_state?

[snarky-snark]

And why remove the await?

[danielbrunt57]

I just checked my installed package and it did not have line 319: await self.async_update_ha_state(True)

        # Restore previous values on startup and reload
        if self._restore == True:
            state = await self.async_get_last_state()
            if state:
                self._value = state.state
                if state.attributes and self._attribute_templates:
                    if not hasattr(self,'_attr_extra_state_attributes'):
                        setattr(self, '_attr_extra_state_attributes', {})
                    for key, template in self._attribute_templates.items():
                        self._attr_extra_state_attributes[key] = state.attributes.get(key)

    async def async_will_remove_from_hass(self):
        # Remove event listeners when the entity is removed from hass (for instance when 'reload' is triggered by user)

I changed both occurences of await self.async_update_ha_state to await self.async_write_ha_state, restarted HA and now have a new error:

I'm not a python programmer but I do have oodles of other programming experience and my guess is...
await self.async_write_ha_state() needs to be self.async_write_ha_state() becase () is null
whereas the next await self.async_write_ha_state(true) is okay because (true) is not null?

[danielbrunt57]

I've restarted HA and my startup automations which reference var completed successfully and there are no other errors.

My installed package (0.15.0) is also missing that line. v0.15.0 (the latest release) was released 18th July, and line 319 was introduced 28th July.

@snarky-snark That change (and many others) seems to have been pushed after 18th July 2022.
