Home Assistant Binary Sensor for Room Occupancy

[pkscout]

I've just got Room Assistant setup, so if this is already available, my apologies for not finding it in the documentation.

I have three devices I'm tracking, and each device will tell me in which room it is. The thing is, almost all my automation logic is based on the room being occupied or not occupied, not who's in it. I setup a template binary sensor in HA for each room that is on if any tracked device is in the room, but that means any time I add another tracker I have to update the sensor template.

To avoid all that, it would be nice if Room Assistant had a set of binary sensors for room occupancy (I'd even be OK with a regular sensor with a count if that's easier) that were published to HA.
