Have it switched on or off by using a tv boolean capability like “Turned on”.
No flows 
In this example:
- TV device:
TV WebOS UJ630V - Virtual presence sensor:
TV V-Presence Sensor
The Virtual presence sensors’ “Presence switch” (Button 1) is used to activate the “Occupancy alarm”;
The TV’s “Turned On” capability is used with Button 1 to activate the virtual device.
And yes, it activates the zone it’s in
