Not compatible with Python 3.11

[syphernl]

After updating Python to 3.11 this component is failing:

Can you try to make a following change in the code (in __init__.py file) and check if it works?

...
-    @asyncio.coroutine
-    def async_added_to_hass(self):
-        state = yield from self.async_get_last_state()
+    async def async_added_to_hass(self):
+        state = await self.async_get_last_state()
         if state is not None \
                 and state.attributes is not None \
...

After changing that a new error popups up:

It looks like you haven't applied all changes from the fragment I have posted above. The updated code should look the following way:

    @property
    def state(self):
        return len(self._entities_db) + len(self._variables_db)

    async def async_added_to_hass(self):
        state = await self.async_get_last_state()
        if state is not None \
                and state.attributes is not None \
                and "variables" in state.attributes and not isinstance(state.attributes["entities"], list) \
                and "entities" in state.attributes and not isinstance(state.attributes["variables"], list):
            self._variables_db = state.attributes["variables"]
            self._entities_db = state.attributes["entities"]

[syphernl]

state = await self.async_get_last_state()

Ah you're right. I only changed the first part earlier today. The full change seems to work fine as entity saver.saver is now back.

[PiotrMachowski]

Great, thank you. I will adjust the integration 👍

Fixed in v1.1.5
