I have a proxy item and I want to update this item with the status changed by another item rule “PROXY state changed test” when Item DoorSensor18_TamperAlarm changed then Thread::sleep(10) postUpdate(DoorSensor18_TamperAlarm_PROXY, DoorSensor18_TamperAlarm.state) end If the item has the same…

I’m not sure where you got that code but it is all kinds of wrong. To call a transform from a rule use the transform action: transform("transform name", "transform argument", "string to transform") So in your case you would use: val trans = transform("MAP", "convert_contact_switch.map", DoorSens…

Ah, I understand, in my case? DoorSensor18_TamperAlarmProxy = transform(“MAP”, “convert_contact_switch.map”, DoorSensor18_TamperAlarm.state.toString)

Like I already said [image] rlkoshak: So in your case you would use: val trans = transform(“MAP”, “convert_contact_switch.map”, DoorSensor18_TamperAlarm.state.toString) Then postUpdate(trans)

It is not working: Rule ‘PROXY state changed test’: An error occured during the script execution: null

Ha now it is working without any changes. I only opened the map file once and closed it. looks like the map file was not read into openhab. Thanks, works perfect now.
