Nest Presence Device Has Many Events

I recently enabled the Nest Presence Device on my hub. I have two thermostats and seven Protects. The presence device works correctly, following the Nest home / away status.

I'm concerned because I took a look at the Events for the Nest Presence Device (on the device page). I found the presence changes, as expected, but I also found many more events named "lastUpdatedDt". These seem to happen at the rate of approximately one per second, and sometimes faster.

Is this expected?

Thanks for any insights.


More of the bugs I have found and fixed.

Still need to figure out how to get updates into HE team.
