Z-Wave Poller
The Z-Wave poller app corrects a polling issue with certain Z-Wave devices that do not display their state properly. The only affects select non-plus Z-wave devices. To determine if your Z-Wave device is a candidate for Z-Wave poller, active your device manually and while you watch your logs. If the device does not register a change of stat in the logs, it is a candidate for Z-Wave Poller. If the device does register a change in the logs, there is no need to use the Poller.
If you activate the device physically and the device doesn't update the driver state, then it could be a candidate for polling.
If you activate the device physically and it updates the driver correctly, then do not poll it.
There are many many non plus devices that report correctly.
