Google calendar reliability

Configuration
1

During recent months it happens a few times that google calendar integration stopped working suddenly without any notification (no even in notification tab).

Every time it was caused by Google which was requesting new consent or so. Until fullfiled, integration were logging 403 errors.

The point is, I got informed about that fact only by automations which stopped working. Which obviously affect overal reliability.

Would be usefull to get know about that as soon as possible. For example being able to send mobile notification triggered by the calendar integration when fails connecting the data source api.

Is there something like that already available in HA? something like possibility to intercept particular errors reported by integration in order to send the notification to ha instance maintainer?

I had similar issues, but i gave up after just a few hours with google calendar.
It was too slow and I wasn’t sure it always worked.

I use microsoft 365 calendar now, using a custom component called tybritten/ical-sensor-homeassistant.
Perhaps you can use this and integrate google calendar with?
You just need the link to the calendar file.
