Rather than notifying temp, would it make sense to notify
trip_pointX_temp when temperature crosses the trip point going up and
trip_pointX_hyst when temperature crosses the trip point going down?
That would allow userspace to watch for only a subset of events by
polling/selecting on the relevant nodes.

This looks vestigial. Remove it?
