Ah, thanks! I wanted to use a map, but couldn’t find the proper search incantation. The solution below seems to be working (note newHashMap not createHashMap 
). To be clear, if I actually wanted the global scope of sharedCache to make a value available between rules, I would need to run a nightly, move to another scripting engine, or wait for a release that includes it for Xtend? No other workaround for global scope?
import java.util.Map
val Map<String, Timer> timers = newHashMap
rule "Motion to Presence"
when
Member of gIndoor_Motion_Sensors changed
then
val triggeringItem = ScriptServiceUtil.getItemRegistry.getItem(triggeringItemName)
val actionItemName = triggeringItem.name.toString.replace("_Motion","_Presence")
if (ScriptServiceUtil.getItemRegistry.getItems(actionItemName).length < 1) return
var actionItem = ScriptServiceUtil.getItemRegistry.getItem( actionItemName )
var newValue = if (triggeringItem.state == OPEN) ON else OFF
logWarn("security", "transforming {}={} to {}={}", triggeringItem.name, triggeringItem.state, actionItem.name, newValue)
var presenceTimer = timers.get(actionItem.name.toString)
if (newValue == ON) {
actionItem.sendCommand(newValue)
if (presenceTimer === null) timers.put(actionItem.name.toString,
createTimer(now.plusSeconds(30)) [|
logWarn("presence", "{} timeout", actionItem.name.toString)
actionItem.sendCommand(OFF)
timers.remove(actionItem.name.toString)
]
) else presenceTimer.reschedule(now.plusSeconds(30))
}
end
