My BTT Smart Filament Sensor 2.0 is cycling between "detected" and "empty" very fast. Result: Immediately after print start false positives for both sensors. Any Idea whats wrong?

I wired a BTT Smart Filament Sensor 2.0 to my BTT Octopus V1.1 @ PG12 & PG14 (Stop 4 & Stop 6). I configured the SFF Sensor according to BTTs manual:

[filament_switch_sensor switch_sensor]
switch_pin: ^PG12
event_delay: 3.0
pause_delay: 2.5
pause_on_runout: False
insert_gcode:
M117 Switch inserted
runout_gcode:
#PAUSE
M117 Switch runout
LCDRGB R=1 G=0 B=0 # Turn LCD red
BEEP I=12

[filament_motion_sensor encoder_sensor]
switch_pin: ^PG14
event_delay: 3.0
pause_delay: 2.5
detection_length: 30.0
extruder: extruder
pause_on_runout: False
insert_gcode:
M117 Encoder inserted
runout_gcode:
#PAUSE
M117 Encoder runout
LCDRGB R=1 G=0 B=0 # Turn LCD red
BEEP I=12

Did you switch the rotary encoder and the switch wiring.
A rotary encoder will close and open rapidly when it's turning.
