Count Events that are consecutively over a certain total time

I would like to know "how many visits to a location are over say 3 minutes" because that will say the person is definently there... I have a large table to sensors that tell where a person is, but need to count the total time for each location and then if( function and count function to see how many times a day a person is say "in the bathroom."

here's the PBIX file...

I can count if each sensor lasts longer than 3 minutes, but want to count if the consecutive events are larger than 3 or 5 minutes.

the hallway here would be the sum of the total duration for that time.  Maybe the date axis is then the min time for each segment of locations?
