I have tried this:
Temperature of Hønsehus - temp (4.63) becomes > 2.0
Off: Høns - Varmeplade
Notify Henrik (hubitat): 'Varmeplade slukket'
However, then I get a massage every time the temperature device gets a reading above 2 degrees (about every hour).
I would like to ONLY activate the action when the temperature goes below 2 degrees ie. crosses the 2 degree line.
