• Vertex group is more than one Vertex. Vertexes in a group communicate with each other without disturbing other groups. Vertex group sees other Vertex groups (routing table) but commands from other Vertex Groups are not received. Using groups you can separate communication between floors, areas, etc.

• Vertex cluster is a system of up to 25 Vertex controllers. Vertexes in the cluster can be connected into groups. All Vertexes in one cluster share the same cluster ID - CUID (a Node.js based identifier with collision-resistant communication). Vertexes in a cluster can be divided into groups.

Vertex Cluster is a system which allows sending information between devices connected to controller(s) and enables you to create a bigger lighting management system.

Some important definitions:

• Vertex Group - is a part of Vertex Cluster. You can separate gateways into Vertex Groups in your cluster. Inside Vertex Group, gateways are communicating each other and send commands. Vertex Group can see other Vertex Groups (routing table), but commands from other Vertex Groups are not received.

• CUID (Cluster Unique Identifier) - is a Node.js based identifier with collision-resistant communication.

To manage your cluster you should enter netconfig NetConfig: http://VERTEX_IP/netconfig/home

...

After that, you will see all units which you want to configure as groups. Vertex group in netconfig it is NOT the same as vertex group in GUI/Node-RED. You have available 15 Vertex groups in one network, so you can create up to 15 stand alone Vertex groups. (recommended limit of Vertex controllers in one cluster is 25.)

Vertex group in netconfig is NOT the same as vertex group in GUI/Node-RED.

...

The last step od netconfig is sending new the configuration to Vertexes with CUID. We You can choose sending to send the configuration with the old CUID or generate a new one (default). It is important when you are replacing one Vertex and don't want to change the setup of a network . (generating a new CUID for Vertexes causes creating a new routing table).

...

For better understanding we can consider all options as examples. We can have, consider these two examples:

1. Vertex controllers in one Vertex group in one cluster in one network

2. 

   Vertex controllers in different Vertex group in one cluster in one network

   

Hardware explanation of clusters

You can see See below the structure diagram of vertex Vertex communication in the cluster. Prosody XMPP server due to routing table is able to trasmit transmit and receive commands or messages to other Vertex prosody XMPP server by ethernet connection.
