+#### AVOID FLAPPING ####
+# For values slowly changing, like a server cabinet temperature, a lot of start/end alarm notifications
+# may be generated if the value is near the limit (e.g. alarm set to 30, temperature jumping between 30.1
+# and 29.9). To avoid this, a "grace" delta can be set with:
+# DELTA=0.5
+# In the previous example, this make the alarm fire at 30.5 and stop at 29.5.
+# If not specified, the delta is 0.
