Is VRTstatus an Item or a variable? You use it as both.

I think you’re looking for something like…

rule "Vaillant_status"
when
    Item VaillantVRT39239200DisplayedRoomTempDisplayedRoomTemp received update
    or
    Item VaillantVRT39239200ActualRoomTempDesiredHc1ActualRoomTempDesiredHc1 received update
    or 
    Item VaillantVRT39239200Hc1OPModeHc1OPMode received update
then
    var newVRTstatus = "OFF"
    if (VaillantVRT39239200Hc1OPModeHc1OPMode.state == 2) {
        newVRTstatus = "AUTO"
    } else if (VaillantVRT39239200Hc1OPModeHc1OPMode.state == 1) {
        newVRTstatus = "MANUAL"
    }
    logInfo("FILE", "newVRTstatus: {}", newVRTstatus)
    VRTstatus.postUpdate(newVRTstatus)
    Vaillant_status.postUpdate(VaillantVRT39239200ActualRoomTempDesiredHc1ActualRoomTempDesiredHc1.state.toString + "°C/" + VaillantVRT39239200DisplayedRoomTempDisplayedRoomTemp.state.toString + "°C/" + newVRTstatus)
end

Thank you.

This is what i’m looking for

By way of explanation, the var exists only within the { } block, and vanishes at the closing }
By defining the var outside the block, it continues to exist before, during, and after the { } block.
