 The subtopic after `home/BTtoMQTT/` is the MAC address of the Bluetooth low energy beacon.  The rssi value is the [RSSI signal level](https://www.metageek.com/training/resources/understanding-rssi.html) from which you may deduce the relative distance to the device.
-Consider the distance as a beta featuer as currently we are not retrieving the emitting power of the beacon to make it more accurate.
