[mdegat01]

Just updated to 0.109 and found this issue in my log
Detected I/O inside the event loop. This is causing stability issues. Please report issue to the custom component author for o365 doing I/O at custom_components/o365/calendar.py, line 158: limit=self.limit, query=query, include_recurring=True

In the release notes of 0.109 (as well as the log) HA team asks any instance of this log entry be reported as an issue on the component.

I notice the setup in init.py isn't configured as async, (I think it should be async def async_setup...), but changing that didn't resolve the problem. So I think the issue is somewhere in the O365 module, which I'll try and do some debug against later. Not sure if it isn't just the fact of a problem with the way O365 queries work...

Last i checked the O365 module was not async at all.

I will investigate when i have the time. But considering my daughter just arrived in the world, i honestly do not know when that will be

I'm planning to take a look. On the asynchronous subject, a number of methods in calendar.py are marked as async, and they seem to get called. Just seems the setup routine isn't async, not sure if it matters. I keep having to google what is achievable, so not sure if I can tell if the thing that is erroring it is actually async or not, I think it gets called from a couple of places. Just spending quality time with family who are off work, whilst I am still full time at my desk.

Congratulations by the way. Sleepless nights ahead, so I understand...

I think the problem is that the calls to O365 are from inside an async routine, but possibly O365 is not async friendly. So I think you need to call them via a hass helper async_create_task as shown here https://developers.home-assistant.io/docs/asyncio_working_with_async. Not sure how many others items may need to be changed like that, I'm only using calendar.

Assuming you don't look at this overnight, I'll try to have a look tomorrow morning.
