Whenever the command queue service is restarted, the events are re-queried and the command queue entries are rebuilt. If you have any active events occurring in the rooms for which you have previously defined equipment, you should see scheduled commands show up in the Active tab of the Command Queue Viewer.
Open the Command Queue window:
Click on the Equipment à Command Queue menu item.
Click on the Active Tab:
This list shows all of the scheduled commands that are waiting to be executed in the next 24 hours.
As commands get executed, they are moved to the History tab of the window.
