Detecting offline Things in a less stupid way

I also believe there is a way to trigger a Rule when a Thing goes offline, though that would require you to add each Thing as a separate trigger to one rule or give each Thing its own rule.

Thanks for inspiring me with this discussion! I added some Thing monitoring to my rules and optimized logging to suppress some unavailable or unhelpful strings from getThingStatusInfo():

rule "TV"
when
    Thing 'samsungtv:tv:14dc9380_XXX' changed
then
    val ThingStatusInfo = getThingStatusInfo("samsungtv:tv:14dc9380_XXX")
    if(ThingStatusInfo===null) return;
    var String thingStatusInfo_Msg = ""
    if(ThingStatusInfo.statusDetail.toString!="NONE")	thingStatusInfo_Msg = thingStatusInfo_Msg + ThingStatusInfo.statusDetail
    if(ThingStatusInfo.description!==null)				thingStatusInfo_Msg = thingStatusInfo_Msg + ThingStatusInfo.description
    if(thingStatusInfo_Msg!="")	logInfo("RULE","@R TV: {} [{}]", ThingStatusInfo.status, thingStatusInfo_Msg)
    else						logInfo("RULE","@R TV: {}", ThingStatusInfo.status)
end

I agree with @rlkoshak that adding a rule for each Thing is suboptimal.
It would be easier if something like triggeringItem exists for Things as you may find in this non-working example:

rule "TV"
when
    Thing 'samsungtv:tv:livingroom' changed or
    Thing 'samsungtv:tv:bedroom' changed or
    Thing 'samsungtv:tv:kitchen' changed
then
    val TriggeredThing = triggeringThing
    val ThingStatusInfo = getThingStatusInfo(TriggeredThing)

Would it make sense to open an issue for this?
