An ignore list sounds useful.  I noticed that when I was querying particular
groups like Temperature, there were some I knew I'd never care about
(e.g. HSC SCSI BP Temp) so it would be nice to just eliminate these up front.

Actually this makes me wonder if there is a better solution namely 
can't you differentiate between sensors that are truly out of range
(ALERT) versus the ones that appear out of range due to a component
not being present?  If you can tell the difference, it would be
nice if you could give these a different tag like maybe "N/A" 
instead of ALERT.
