Filament out Sensor with octoprint on raspberry drives me crazy...

Printing with octoprint everything works fine - everything BUT filament out sensor couses trouble.
Tested "Filament Sensor" & "Filame nt Sensor reloaded" plugins without any succes. Only "Filament Sensor NG" works - at least sometimes.
After adding pull up circut to switch (it´s a big switch with some spring that would do for a mouse trap) raspberry now is capable to sense switch state quite error free. The Problem if I do set plugin option for "Event Confirmations" on less than 10 the Gcode defined for "Pause" is triggered twice by plugin. And cause gcode lifts the print head relative 10 mm it ends up 20 mm lifted. So "Pause end" gcode with 10mm down won´t work as intended. And even with 10 Event confirmations it happens every now and then that Pause is triggered twice.
Any Idea how to prevent double triggering pause gcode? More confimations won´t work, for it causes too much filament beeing printed after leaving the sensor switch empty.
Another Idea would be not to lift the head, but park it on same level in leftmost back corner of printbed? Octolapse does something similar before taking a snapsnot. Could not find out how to go to corner and come back to last print position on same level. This only would work if the somehow stored last print position is not corrupted by a doubled back left command... but how to store the last printed position with gcode?
Any idea on any of those questions - or a reliable solution to get octoprint on raspberry handling filament out in a save way?
