By coincidence I have just posted with the exact same issue - mid air probing.
My probe is set up so that when the probe is deployed ie below the extruder M119 reports open. When the bed is hit M119 reports triggered. I assumed this was correct. Maybe not.
If anyone has the definitive answer I would be grateful. Btw the probe switch is wired Normally open so it's closed when the probe is deployed. It's connected to the Z min input on my Rumba (another coincidence ?)
