I find this really great what you can do everything.
I have recently started to deal with it and therefore I do not know it well.
My plan is to install an esp32 with openmqttgateway in each room.
About Bluetooth should be recognized who is in the house / room.
How can I make it so that only certain mac addresses are scanned and only those are transmitted via mqtt.
I use iobroker and would like to check the presence.
can someone help me ?
