MQTT Rule send another MQTT Message

I am trying to forward a message if I state change to 0 (OFF) or 1 (ON).

My item:

Switch SwitchDoo_Switch "SwitchDoo" ["Lighting"] {mqtt=">[broker:/switch/gpio/5:command:ON:1],>[broker:/switch/gpio/5:command:OFF:0],<[broker:/switch/door/state:command:OFF:0],<[broker:/switch/door/state:command:ON:1]", autoupdate="false"}
String VT_Notify_Alarm { mqtt=">[broker:/openhab/notification/alarm:state:*:default]" }

My rule:

rule "SwitchDoo"
when
	Item SwitchDoo changed
then
    if (SwitchDoo.state == 1) {
        VT_Notify_Alarm.postUpdate("Haustor offen")
    } else {
        VT_Notify_Alarm.postUpdate("Haustor geschlossen")
    }
end

MQTT output:

/switch/gpio/5
0
/switch/gpio/5
1

How can I post VT_Notify_Alarm.postUpdate("Haustor offen") if state is 1 ?

I checked this Using MQTT command for Switch Item and this [SOLVED] Switch and icon update via MQTT but none of them worked.

I think you have to change :

String VT_Notify_Alarm { mqtt=">[broker:/openhab/notification/alarm:command:*:default]" }

change state to command and in rules if it’s not working with postUpdate try with sendCommand, at least this is working for me.

Thanks
