Primary z-wave controller

Community Playground General Discussions

Hi,

Since I am new to this z-wave stuff, here’s a general question: why does the z-wave network need primary and secondary controllers (a.k.a. what’s one and what’s the second)? Next, can Vera function as a secondary controller or (a) it must be primary (b) while not necessary, it is recommended to be primary controller?

Thank you,

George

Check http://zwaveworld.com, the site has few very well written articles on z-wave basics.

Definitions:

Primary Controller:

This is a device that contains a description of the Z-Wave network and is used for:

  • Inclusion -adding new devices to the network
  • Exclusion- removing devices from the network
  • Association - creating links between two or more devices so they can exchange information or commands
  • Replication - receiving and transferring network information from or to other controllers.
  • Other functions depending upon model of control

Secondary Controller:

A controller that has the functionality of a primary controller but with one limitation; it cannot include or exclude nodes from the Z-Wave system.

Vera(Z-Stick/Dongle) can function as primary controller or secondary controller as primary the system has more capabilities.
