The secret is not caring it's 4m away as long as it says you're closest to that one. It's not accurate, it's a guess made with software.
As I've said I've sat at my PC on the front room and watched it say I'm in my bedroom and kitchen.
So for example my front room lights are based around an input boolean. They're triggered on by motion but back off by whether the TV is on, my wife's laptop is connected to the WiFi, the pc is switched off, and everyone's presence is not in the front room. I already did all that and now I have presence as well.
It used to be that my wife would be sat there on her phone and the lights would go out, now because her phone is on her person they stay on.
Like I say, they're not perfect but they are better than not having them.
I don't think I'll ever have my music follow me around the house.
Oh also try instead of basing automations around whether you are in a room, instead use "is not"
So for example when I get out of bed and get up for work by bedroom lights come on with my alarm. When I go downstairs and make a brew I am no longer in the bedroom so my automations turn off the lights in there. Is not "bedroom"
It's triggered by the motion sensor outside my bedroom door, then it waits for my presence to be anything other than bedroom. Since I'm moving around the house it'll trigger at some point.
Similarly my sleep automation turns off when the bedroom is no longer occupied. But that's when my wife gets up 2 hours after me. It's also triggered by motion, but then waits until my bedroom presence sensor no longer reads anything
