init(self, single=True)
(Constructor)

source code

Initalizer

Parameters:

single (boolean) - collect from a single device?

Overrides: zenmodeler.ZenModeler.__init__

config(self)

source code

Get the DiscoverService

Returns: function: a DiscoverService from zenhub
Overrides: zenmodeler.ZenModeler.config

discoverIps(self, nets)

source code

Parameters:

nets (list) - list of networks to discover

Returns: Twisted deferred

successful result is a list of IPs that were added

discoverRanges(self, driver)

source code

Ping all IPs in the range and create devices for the ones that come back.

Parameters:
