I believe the other comment is correct, there's 2 ways of adding Bluetooth presence, one is espresence which I'm using and the other is a less feature filled version in esphome.
I have done a lot of moving my esp boards around though to improve it. They seem to work better when they're in different locations.
So for example I had one at the top of my stairs but I've moved it across the room, further away from the one on the floor below which was at the bottom of the same stairs. I also moved that one into a room and higher up because it was interfering with the one on the floor below that.
And that one I moved to the other side of the room, and the one on my ground floor has been dropped to floor level instead of sitting at waist height.
Point being, if you're putting it onto already placed sensors, ymmv
