Hi,
For anybody interested in presence detection using BLE devices, I was able to have this kind of detection working for eedomus.
However you have to setup a dedicated tool on a linux (raspberry for instance) managin BLE interface, because eedomus isn't compatible with BLE for the time being.
Nevertheless installation is not so complicated.
Everything is explained in this post :
