Smartd version? Platform?

If state persistence is used, only one mail per day will be sent by 
default, even if smartd is restarted. See '-s' command line option on 
smartd man page and '-M daily' directive on smartd.conf man page.

Please check smartd syslog output for related messages ("Temperature ... 
reached critical limit ...").

Remove the .state file.
Or temporarily set e.g. '-W 0,0,50' to reset the email warning counter.

190 is used if 194 does not exist. A possible drive database should 
specify '-v 190,tempminmax,...'.
If 194 exists but does not return temperature, try to add '-v 
194,Unknown' to smartd.conf entry.

Sorry, no. Feel free to suggest an enhancement in our Trac:
