Hello,
i try to use the Networkbinding and my iPhone for a presence detection.
The Problem is that after a few minutes the Networkbinding cant find my iPhone.
In found a part in Manuel for iphone dectection: Link
my Thing:
Anyone have an idea what i can do?
Do you have arping installed, configured, and verify that it works?
Sometimes I had the same problems. I think that there are problems with Bonjour and the iPhone simply can not be awakened and thus can not be pinged. But this is not a problem of the Network Binding, but a general network problem. I often had the same problems with the Bonjour Sleep Proxy. That my Apple TV could not access the private share. As a router, I use a Fritzbox, probably there is the ZeroConf integration buggy 
Of course, this does not help you much
I have now switched to a Bluetooth presence detection, which is very reliable 
Raspberry PI Zero W + Gigaset G-Tag (or other BT Tags) + Little Script
If you are interested or have questions write me a PN … I have not written any README.
PS: I speak German, if you write me a PN and even speak German
