Why is my Activity list empty?
If you want to see what listed activity/events look like, we suggest that you Arm or Disarm your system, or bypass one of its sensors to create activity that will appear on the list. You can also go to Locations and select SYNC USERS or SYNC PANEL. These changes in the system's status will appear in the Activity log.
You might want to experiment with filtering and sorting options in the list. See the FAQ How can I Filter the Activities (events) logged by my system?
