ok..

ok Xavier aswered with the solution!

I hadn't temp1_input (i also have the number inverted i.e. i have 
tempNUMBER_input instead of temp_inputNUMBER.. dunno why ;)) maybe this 
helps someone else too..

and so.. not having temp1_input in my sensors dir in sysfs I forced it 
with      i2c_sensors-path '/sys/bus/i2c/devices/1-6000/'
and everything went well..

I put also a      expression (i2c_sensors('temp3_input')*71)/73-72.41
line in my .conf and now the temperature gets read..

I think some doc of the .conf file would really help ;)
for instance i also dunno how to read for instance the cpu freq from 
/proc/cpuinfo with the function instead of doing a stupid system call to 
cat and grep it.. ;)
It would also be super if it would be possible to read smart tags from 
hard drives!! for instance I use now a small soft called hddtemp to read 
my temp of the hard drive via smart.. but also in this case i need to do 
a system call forking to ask temperature every when..

actually not.. I tried to get aout of the conf all this icon definitions 
because I thought they could redefine my chars off.. but it didn't 
help.. if I have a conf with also just one bar defined.. this bar can go 
either est or north no way to having it west or south.. even if it is 
the only bar defined.. uhm...

interesting feature! so i will try to recompile and see the difference 
in cpu usage.. just cant understand why i didn't have the .h file in the 
/usr/include/asm/ dir.. uhm.. and i have sources installed.. maybe it is 
just a link some script didn't put in place.. uhm...

ok, sure i will =)
maybe by holding the maximum value for some milliseconds after which it 
gets recaluclated from scratch.. uhm..

anyway real cool job with this program!
maybe if i have some time i would gladly help to contribute.. maybe with 
this thing about smart tag reading.. I'll look in the plugin creation 
instructions.. ;)
