trip_type should also be part of the event because trip_down/trip_up
for hot trip and cold trip have different meanings.
Or can we use some more generic names like trip_on/trip_off? trip_on
means the trip point is violated or actions need to be taken for the
specific trip points, for both hot and cold trips. I know
trip_on/trip_off doesn't represent what I mean clearly, but surely you
can find a better name.
thanks,
