Hi guys . i’m new on the openhab and i have some problems.i want to automate my lights but at a button press i wanna change light state ( ON-Off and reverse) :)) . i wrote the code but is not working .

this is my items tab :

//Relays
Switch channela “Bec Interior” { gpio=“pin:26 activelow:yes initialValue:high” }
Switch channel2 “Bec Exterior” { gpio=“pin:19 activelow:yes initialValue:high” }
Switch channel3 “Channel 3” { gpio=“pin:13 activelow:yes initialValue:high”}
Switch channel4 “Channel 4” { gpio=“pin:6 activelow:yes initialValue:high”}

Contact DoorSensor “Door Sensor [%s]” { gpio=“pin:16 debounce:10 activelow:yes” }
Contact contact_interior { gpio=“pin:24 debounce:30 activelow:yes” }

and this is my rules tab:

rule “Update light when button pressed”
when
Item contact_interior changed from OPEN to CLOSED
then
if(channela.state == ON){sendCommand(channela,OFF)
//LogInfo(“interior”,“Switching to OFF”)
}
else{ sendCommand(channela,OFF)
//LogInfo(“interior”,“Switching to OFF”)
}
end

and this is my sitemap tab:

sitemap home label=“Andy’s House”
{

   Switch item=channela
   Switch item=channel2
   Switch item=channel3
   Switch item=channel4

   Text item=contact_interior
   Text item=DoorSensor

idk what i’m doing wrong . when the button is pressed . nothing happens

You are setting it to OFF in both cases!

rule “Update light when button pressed”
when
    Item contact_interior changed from OPEN to CLOSED
then
    if(channela.state == ON) {
        channela.sendCommand(OFF)
        //logInfo(“interior”,“Switching to OFF”)
    } else {
        channela.sendCommand(ON)
        //logInfo(“interior”,“Switching to ON”)
    }
end

What happens in the log when you press the button?

Please note the syntax item.sendCommand(COMMAND) instead of sendCommand(Item, COMMAND)

It is recommended to use the first one and only use the second one for group commands and the like.
