"Comparisson" events

OK - a very specific question here. I want to add a “goes below” type event to a plugin - similar to the “temperature goes above” event on the thermostat device. It works as designed, but I only want it to fire a scene the first time that it goes below, not everytime the plugin reports a value below the comparison value. So in other words, if I creat a “goes below” 100 event, when the plugin report values 99, 98, 97, 96…, i only want to fire at 99, not at all values.
Anyone have any thoughts?

Bump… any thoughts here?

MCV, is what I’m experiencing here normal?
