Enable/Disable Occupancy Sensor via Intergration

I checked the integration protocol and I couldn't find a way to directly enable/disable an occupancy sensor via the integration commands.

Could I make two time clock event that is not enabled on any day. And then send the #TIMECLOCK,4,5,3,<CR><LF> command to be used to trigger the the commands?

You are on the right track if you want a third party to control the vacancy/occupancy setting.
