I ran across this RSSI to Distance repo and tried it, it works fairly good and thought i’d post it here. I imagine i’m not the only one who has been banging my head trying to get a working and reliable room level presense detection. I’ve been using Espresense and it works fairly good but you have limited options if you want to make full use of your esp32 and add sensors and what not. One thing i’ve noticed is it works best if the beacon and esp32 are within line of sight because any barriers between the two will increase the distance. Here is the repo, you need to upload the 2 .h files into your config/esphome/custom_components directory and then change your esp32 config accordingly. Here is a sample I used for testing.

Also, If you are using BlueCharm Beacons this will create a sensor for your beacon battery.
