Scent delivery system scheduling

A scent delivery system comprising:

• one or more scent delivery units;
• and
• one or more computers and one or more storage devices storing instructions that are operable, if executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• maintaining one or more scheduled events, each scheduled event being associated with control logic that identifies the one or more scent delivery units to be activated during a first time period, the first time period being defined by an activation start time and an activation end time,
• maintaining one or more scheduled anti-events, each scheduled anti-event being associated with control logic that identifies the one or more scent delivery units to be deactivated during a second time period, the second time period being defined by a deactivation start time and a deactivation end time, and associated with at least one of a scent type and a location of the one or more scent delivery units, and
• generating, based on the one or more scheduled events and the one or more scheduled anti-events, command data to be communicated to the one or more scent delivery units to control activation and deactivation of the one or more scent delivery units,
• wherein generating the command data includes:
• identifying a conflicting period of time during which control specified by the one or more scheduled events for the one or more scent delivery units differs from control specified by the one or more scheduled anti-events for the one or more scent delivery units, and
• generating command data that gives priority to control specified by the one or more scheduled anti-events, control for the one or more scent delivery units being in accordance with the control logic of the one or more scheduled anti-events during the conflicting period of time and not in accordance with the control logic of the one or more scheduled events during the conflicting period of time.
