Best way to alert once for multiple sensors

I have a room with multiple temperature sensors that I am monitoring via
SNMP.  I would like to set Nagios up such that we only get one alert
about any of the sensors going out-of-range (since usually the others
will follow over time).

I have set a servicedependency chain from sensor 1 to 2 to ..., but that
only helps if #1 is the first to alert.  If #2 gets hot before #1, I'll
get an alert for #2 and then #1.  Right now, I've tried to "rank" them
in order of most-likely to overheat to least-likely, but that won't
really work.

Is there a good solution to this?
