As @brad mentioned, now that I've added more esp32 proxies for using in my #HomeAssistant Bermuda BLE Room Presence, I'm finding that the detection of the correct room is becoming a problem. Mostly because the position of the proxies is not great.
The bedroom one is behind a mirror (where there is an outlet) and the living room one is not far behind a wall, but there are windows to the yard where the RF from my phone could easily be stronger to the living room than to the bedroom one.
The ideal location of these esp32 proxies would be the ceiling, where the RF performance would be best, but not easy to do when you're dealing with wired power in a home where running wires isn't the easiest.
I've spent some time with calibration and it's pretty tricky getting values right when physical obstacles and line of sight issues are part of the challenge of where to put them.
