I've been playing with it also. Here is a section for laptops that shows wifi and battery:
Code:
NETWORK ${hr 1}
${if_up eth0}
${alignc}eth0
Up: ${alignr}${upspeed eth0}KB/s
Total: ${alignr}${totalup eth0}
Down: ${alignr}${downspeed eth0}KB/s
Total: ${alignr}${totaldown eth0}
$endif${if_up eth1}
${alignc}eth1
ESSID: ${alignr}${wireless_essid eth1}
Bitrate: ${alignr}${wireless_bitrate eth1}
Signal: ${wireless_link_qual_perc eth1}% ${wireless_link_bar eth1}
Up: ${alignr}${upspeed eth1}KB/s
Total: ${alignr}${totalup eth1}
Down: ${alignr}${downspeed eth1}KB/s
Total: ${alignr}${totaldown eth1}
$endif
BATTERY ${hr 1}
Battery: ${battery_percent}% ${battery_bar}
Battery Time: ${alignr}${battery_time}
You will need to compile conky with --enable-wlan to get the wifi to work. Also note that on my laptop eth0 is wired and eth1 is wifi. If yours is different you will need to change it.
