Is anyone using Fing for presence

Rather than drag a 2 year old post up from the dead, I thought it better to just start new. Is anyone using Fing (either just the apps or box) for presence? I've sorta been playing with it on an off for a few months, with the new update showing when users are home or not (I believe it s Wi-Fi presence) i was wondering if anyone is using Fing either by its self or as par of an aggregate presence app? If so how did you set it up?
