I don’t have a presence sensor in my living room and I don’t think I will ever put one there because of aesthetic reasons. I would like to be able to use my TV being “on” as a way to make a zone “active”. I already do this with my flows but it would be cool to make any device a “presence” device if it is on.
You can create a virtual motion- or presence sensor.
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
