I use rssi to find my stuff regularly. There are a ton of android apps to do it. I also use it for room presence detection with homeassistant (using the BLE in my ESP32s and Shelly switches).

Bluetoothctl in Linux.

Have done exactly this 15 years ago to find my lost phone (:

Also wrote a cheap 30 line shell script to allow playing videos and music to “follow me” from one room to another with well placed raspberry pi’s, 11 years ago
