Ooo, think is an interesting and good point.
I’m not sure what the entity filter is on the person entity
Edit: it seems that it is filtered for device_trackers only and I’m not sure of a built-in way I could optionally turn the Bayesian sensor into a device tracker.
In the meantime there is some discussion of doing this with an automation here that you might find helpful:
It relies on a little know action device_tracker.see which allows one to manually change the state of a device_tracker.
If you find a simple, elegant and ideally blueprint able way of doing this then I could add it to the Bayesian Docs.
