The Usage Report shows how many hours and minutes a location has been in use during a defined period. It does not show the specific times when people were present—only the total duration of use.
This function is useful, for example, when prioritizing cleaning tasks (such as in public restrooms or similar spaces).
The report is delivered by email, not as a PDF file.
If you're interested in knowing when during the day the location was used, please refer to the Indoor Climate Report instead.
