GPIO binding problem with get GPIO state

Add-ons Bindings
1

Hello,
version OpenHab and GPIO:
openHAB 2.4.0 Build #1447
binding-gpio1 - 1.13.0.SNAPSHOT

i run GPIO binding on openhab2 and a have button in GPIO17 and 3,3V
my /etc/rc.local:

sudo usermod -a -G dialout openhab
echo 17 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio17/direction

echo 22 >/sys/class/gpio/export
echo out >/sys/class/gpio/gpio22/direction

when button is press (have state OPEN in openhab, in command line 1) led on gpio22 should by change state to ON in openhab, 1 in command line, sometimes its working, one time to 2-3 pressed button, where is the problem in openhab2 ?
this is OK, button press and led is on:

pi@raspberrypi:~ $ cat /sys/class/gpio/gpio17/value
1
pi@raspberrypi:~ $ cat /sys/class/gpio/gpio22/value
1

button is not press and led is off:

pi@raspberrypi:~ $ cat /sys/class/gpio/gpio17/value
0
pi@raspberrypi:~ $ cat /sys/class/gpio/gpio22/value
0

and sometimes when button is press led isnt OFF and i do not know why:

pi@raspberrypi:~ $ cat /sys/class/gpio/gpio17/value
1
pi@raspberrypi:~ $ cat /sys/class/gpio/gpio22/value
0

Button is connected to 3,3V GPIO and to GPIO17 by the 1K resistor and to GND by the 10K resistor

this is rules code but i thing isnt bed:

rule "Status door I"
when
Item DrzwiI changed from OPEN to CLOSED
or
Item DrzwiI changed from CLOSED to OPEN
then
if (DrzwiI.state == OPEN) {
LEDI.sendCommand(ON)
Alarm_DoorI.postUpdate(ON)
} else if (DrzwiI.state == CLOSED) {
LEDI.sendCommand(OFF)
Alarm_DoorI.postUpdate(OFF)
}
end

You didn’t post your Item definitions
remember that postUpdate does not send a command to the Item (and to its binding)
it just updates that state of the Item within OH2

My item definicion:


Contact DrzwiI "Drzwi I [%s]" { gpio="pin:17 debounce:10 activelow:yes" }
Contact DrzwiII "Drzwi II [%s]" { gpio="pin:27 debounce:10 activelow:yes" }

Switch LEDI "LED I" { gpio="pin:22" }
Switch LEDII "LED II" { gpio="pin:23" }

Switch Alarm_DoorI "Alarm I"
Switch Alarm_DoorII "Alarm II"

postupdate is only test to change state in Basic UI you can ignore it

First thing is to look in events.log to see what openHAB thinks is going on i.e. do you see change events,

No, i do not see in events.log change the state even button is press.
I thing problem is in communication betwen GPIO and Openhab2
