Use nmap and put something like this:
${color0}${font DroidSans:size=8}Devices on Studio-wifi:
${color0}${font DroidSans:size=8}${execpi 120 nmap -sP -oG - 10.42.0.0/24 | awk '/Host:/{ print $2," "," " substr($3, 2, length($3) - 2) }'}
in a conky and the ip numbers will show on your desktop, enter known devices in your hosts file and you get the full device names.
