My (admittedly limited) knowledge on the subject of Polling – and, yes, it has been a perennial problem for users since at least 2011! – is that there are TWO parallel mechanisms by which Z-Wave devices get polled.
One is by the Z-Wave chip itself, at the protocol level, a function which cannot be disabled.
The other is by the Vera controller, at the OS level, a function which can be disabled by setting ‘PollSettings’ to 0 (recommended, esp. for battery-operated devices). Disabling this feature does not stop the Z-Wave chip from doing its thing, nor from those dratted red flags appearing.
