Why does the driver need me to specify the zones being used?

The driver needs to properly poll each zone defined in the system separately. By specifying the exact zones that are used, it will allow the processor to ignore non-used zones and quickly get the needed information. Note that this is not intended to be a way to exclude zones from being monitored. If you do not want a zone to be monitored, then you’ll have to configure it as such on the Elk panel.
