Until a new 2.0 version of the binding is released I cannot recommend using the BT binding. I never was able to get it to work on Linux.
A couple options you have for BT presence detection are:
Use the above in conjunction with Network binding and you will have a pretty reliable solution.

@thete, I’ve found that Network is not very reliable with phones. A lot of phones, iPhone in particular, turn off their network when they go to sleep and stop responding to pings as a result. There are some approaches to overcome this using hping3 but over all they tend to be unsatisfactory.
Also, I didn’t know the Network binding now supports autodiscovery. That’s kind of cool.
