I recently changed to openhab2 and am struggling with getting my presence detection back to work.
I am followed the instruction on
https://docs.openhab.org/addons/bindings/network/readme.html#binding-configuration and installed
apt-get install iputils-arping
and gave it elevated access rights by
chmod u+s /usr/bin/arping
thus in the item properties I still see
uses_dhcp_listen no
dhcp_state No access right for port 67. Bound to port 6767 instead. Port forwarding necessary!
presence_detection_type ARP_PING, ICMP_PING
arp_state IPUTILS_ARPING
uses_ios_wakeup On
icmp_state IPUTILS_LINUX_PING
uses_arp_pings no
and i don’t know what else to do
