QT OpenZwave - list node(s) "unavailable" / "unreacheable"

For the QT OpenZwave (beta) integration, is there an option to “list” devices that are not available anymore? Thus e.g. battery operated devices that drained (instantly) and/or defective devices?

I come from a “Vera” world and I was damned by the “can’t detect device” messages. Though they were helpful if they were only doing what they were made for.

Is there such a “feature” or “option” in QT OpenZwave?

Thus if a device has not reported or missed reporting back to the controller within the wake-up interval it is reported as “unreachable/unavailable”?
