[smartmontools-support] -W option of smartd version 5.38 doesn't work as it should

[FritzWare <tec...@fr...>]

Hi,
I'm using smartd from "smartmontools-5.38 released 2008/03/10 at  
10:44:07 GMT".

My configuration is: DEVICESCAN -a -I 194 -W 5,45,55 -R 5 -s (L/../../ 
1/07|S/../.././07)

So, smartd should report temperature changes of more than 5 degrees,  
but it also reports smaller changes.


Here some info from the logfile:

Does anyone know if there is a workaround to not report small  
temperature changes?
