Nodes, Controllers and Home Control Groups
Nodes are controllers or slaves based on their Role Type.
The term U nknown device refers to:
1) Devices that belong to a Home Control Group but are not supported by an eZLO Hub.
2) Devices that do not fit into any of the Home Control Groups managed by the eZLO Hub.
As a Universal Controller, eZLO Hub supports Basic Command Class and thus it can send Basic ON/OFF
commands to turn ON/OFF every individual Unknown Device.
Note: Unknown Devices can only be controlled with Basic ON/OFF commands.
Note: Controller devices can also be handled as Unknown Devices if they do not fit into any of the Home
Control Groups managed by eZLO Hub.
Home Control Groups (HCG) are logical groups with various Z-Wave Plus Device Types mapped in
them.
Controllers are designed to control one or more Home Control Groups. They are classified as either
Dedicated or Universal.
●
A Dedicated Controller must only control one Home Control Group. It may control Unknown
Devices via the Basic Command Class, and the optional implemented controlled command
classes in the controller.
●
A Universal Controller controls multiple Home Control Groups. It MUST be able to control
Unknown Devices with the Basic Command Class together with the optional implemented
controlled command classes. It MUST provide individual control of Unknown Devices that have
been included in the network.
Note : All controls for sending Controlled Commands are displayed in the eZLO Hub web interface
according to the type/role the device reports to the eZLO Hub. For example, for Switch devices the
"Switch" control graphic is displayed, and for thermostats - the "Temperature Setpoint" graphic is
displayed etc.
By their enabled properties, controllers can also be P rimary , I nclusion, SIS a nd Secondary .
The P rimary Static Controller (SC) will automatically update a SUC (Static Update Controller) if present
in the Z-Wave network. Only one Primary controller is allowed in the Z-Wave network.
If the SC is the first node in a network it will automatically be configured to act as P rimary SC .
If the SC is not the first node in a network it will automatically be configured to act as S econdary SC .
Several Secondary SCs are allowed in the Z-Wave network.
The S tatic Inclusion Server (SIS) enables other controllers to include/exclude nodes in the network on
its behalf. The SIS is the Primary controller in the network because it has the latest update of the network
topology and capability to include/exclude nodes in the network. When including additional controllers to
the network they become Inclusion controllers because they have the capability to include/exclude nodes
in the network on behalf of the SIS. The SIS cannot shift its primary role to other controllers in the
network.
Note: eZLO Hub automatically assing SIS role to itself if it's the first SC in the network.
